Re: Virtual Hosting and SSL
Strike that--I just found that documentation after looking the hundredth time. I guess we overlook what we didn't know before, assuming it isn't what we wanted to find--or something strange like that. But I found it. Thanks everyone.

Re: JSP Newbie seeking guidance
John, If you need help with setting up the environment I described (and BOY could I have used help my first time--mostly I tutored myself and failed and failed before succeeding) you can ask me and I will know at least where to point you for relevant information. I assume you have done your own building of software packages from source like PostgreSQL, but if you haven't, that alone can feel like a daunting task--really, its quite simple. Just email me directly and I'll fill you in as much as I can. Justin --- John Geiger <[EMAIL PROTECTED]> wrote: > Not at all, Justin.

Virtual Hosting and SSL
I am running tomcat 5.5.12 and need to host two sites, both with ssl. Obviously one SSL cert/keystore will not do for two sites. I understand that SSL is IP based because the http header is not read until after the connection is established. I know you can configure tomcat to do virtual hosting based on IP's by adding IPVHost="true" to connectors in server.xml file. but you have to specify the keystore a connector will use PER the connector--NOT THE HOST. So even though I can distinguish between IP addresses, it is too late already. The connector has already opened the keystore--without understanding which IP address the request has come from. Can you set up two connectors (one port 443 and one port 80) for one specific ip address and another set of connectors for another ip address? This seems to me (and I am sometimes wrong) the logical way tomcat should work. What good is virtual hosting capability based on IP's if you can't use SSL in conjunction with them? Everybody needs some SSL these days for something or other. Can you tell jsvc to make the daemon listen only on one ip address when you start it, and simply start two dameons listening to different IP's (which would mean two servers running on my machine, and NOT the scenario I would prefer)? I hope some very seasoned pserson can help me. This list has never failed me yet and I have been asking questions for over a year. Mad-Props to all of you! Thanks for everything. Justin __ Yahoo!

Re: JSP Newbie seeking guidance
I would HIGHLY recommend using SuSE Linux 10 which can be purchased or download from Novell directly at suse.com. Also, see the openSuSE project (essentially the open source community effort half of the SuSE/novell team). I used to run RedHat but was disappointed in the drop to Fedora. I tried SuSE a few years ago and have never looked back. So easy to install and configure. The YaST systems management tool is amazing. You can still do everything the manual way (and I do sometimes). But the firewall is easy and strong, the package management is simple, the install resizes partitions (even NTFS). Just so many highly polished surfaces there. Try SuSE and see if you ever go back. I have run tomcat and SuSE in production for over a year and not had a problem and am now in the process of upgrading my production server to SuSE 10 and tomcat 5.5.12. So far so good. It's all working in my development area. The improvements in 5.5.12 are EXCELLENT. But there are significant changes in how you set up the server.xml file, so read up on the 5.5 doc page. I had previously only been using 5.0.x. ALso, I had some glitchy problems with 5.5.9. No reason to download it now anyhow, since 5.5.12 is stable release. I also recommend PostgreSQL 8.0 from postgresql.org if you need database (as i imagine you must) (open source and fully ansiSQL standard and RDBMS compliant, unlike mySQL --don't yell at me for saying so, please-- i know how much many people love mySQL. You have to build Postgresql from source on SuSE 10 since no rpms are out in the combination of those versions of SuSE and PGSQL. I tired to use older RPMS--not a good idea. But the build and install went perfectly. Be sure you have the proper dev packages installed before you try. If not, the documentation tells all you need to know. PostgreSQL 8.0, Tomcat 5.5.12, and SuSE 10 are real winners. I have had --no-- problems with the past versions, and these new versions seem up to par or better. I LOVE SuSE 10.0 for my desktop environment/school computing/web surfing/DVD watching(i use KDE) and run everything just described on my Dell Inspiron 6000 notebook. That's my developemnt envrionment. Obviously the combination of KDE and the servers on a notebook are no match for my production environment. but I must say, my notebook and the software on it do all I ever ask them to--school work, web surfing, large SQL routines, JVM, Tomcat--and a fair bit of graphics design. All on open source software. What a wonderful world we live in. (The DVD's I run on XINE, which I had to build, since XINE is stripped down for leagal reasons in SuSE 10, but the build installed great and runs with no problem just by typing xine in KDE).

Resizing JPEG Images
I am accepting JPEG uploads on a website I developed in JSP and Java Beans. It all runs on Tomcat. I once knew of a Java Bean that would accept a JPEG and scale and resize the image and save it. I need my web-app to resize the images as it accpets them. That was years ago. I can't find it any longer. Does anyone know how or where I should start? If writing my own bean would be easy using some part of the Enterprise Java SDK, please point me in the right direction and I'll do the work. I am using the lates version of the JDK.

JNDI DBCP Resources: Pool Leak
Concerning JNDI Database Connection Pooling Sources, I
have read that if you fail to explicitely close Result
Sets, Statements, or Connections to the DataSource
from WITHIN the web application, a connection in the
pool will be "lost." (I read this at:
http://jakarta.apache.org/tomcat/tomcat-5.5-doc/jndi-datasource-examples-howto.html).
I understand that you can set an option to reclaim
"lost" connections. That's great.
But to avoid this in the first place, I have a
question.
I have a JSP which sends Statement objects to a Bean
(not a bean by exact definition) which accesses the
database and returns a ResultSet.
The jsp code is like this:
<% com.x.DatabaseInterface web = new
com.x.DatabaseInterface(); %>
<% web.connect(); %>
<% String selectSQL = "SELECT * FROM place;"; %>
<% ResultSet result = web.selectQuery(selectSQL); %>
<% while ( result.next() ) { %>
<%= result.getString("placename") %>
<% } %>
<% web.disconnect(); %>
Of course, there are statement objects and resultset
objects in the code above. Do I have to explicitely
close them IN JSP AND also the ones IN THE BEAN or
just the ones in the BEAN? I suppose this is a
fundamental principle of Java which I do not fully
understand as the objects . Can someone please
enlighten me?
The Bean looks like this:
package com.;
import java.sql.*;
import javax.sql.*;
import java.io.*;
import javax.naming.InitialContext;
import javax.naming.Context;
public class DatabaseInterface {
String error;
DataSource ;
Connection database;
ResultSet result;
Statement select;
Statement update;
public DatabaseInterface() { }
public void connect() throws Exception {
try {
InitialContext initContext = new InitialContext();
= (DataSource)
initContext.lookup("java:comp/env/jdbc/");
database = .getConnection();
} catch (Exception e) {
error = "Data Source Opening Connection Error: " +
e;
throw new Exception(error);
}
}
public void disconnect() throws Exception {
try {
database.close();
} catch (Exception e) {
error = "Data Source Closing Connection Error: " +
e;
throw new Exception(error);
}
}
public ResultSet selectQuery(String webStatement)
throws SQLException, Exception {
try {
if ( database != null) {
select = database.createStatement();
result = select.executeQuery(webStatement);
}
} catch (SQLException sqle) {
error = "SQL Error Disconnecting: " + sqle;
throw new SQLException(error);
} catch (Exception e) {
error = "Error in selectQuery block:" + e;
throw new Exception(e);
}
return result;
}
public void insertQuery(String webStatement) throws
SQLException, Exception {
try {
if ( database != null) {
update = database.createStatement();
update.execute(webStatement);
}
} catch (SQLException sqle) {
error = "SQL Error: " + sqle;
throw new SQLException(error);
} catch (Exception e) {
error = "Error in insertQuery block:" + e;
throw new Exception(e);
}
}
}

Re: How bind Tomcat to an IP address?
Andrea, Let's say you install tomcat on machine A, (your server), and your network administrator has given that machine the address of 192.168.0.7. You and want to reach the server from a machine B, your workstation. All you need to do (assuming they are on the same network and properly configured, which are NOT tomcat issues) is sit down at the workstation, machine B, and open your browser. Enter the address of the server (here, 192.168.0.7:8080). Thats it. No "address"=xxx.xxx.xxx field is needed. Ommit them from your server.xml file unless you plan to have your server host virtual domains based on IP address. "Usually" a machine only has one IP address, but even so, if you do not set up the address parameter in your server.xml file, tomcat should listen to all the network devices on the server and respond to your requests to each of the IP's. If this does not answer your question, either I misunderstood it altogether and you need to be more specific about what you are trying to do, or you might try a brief chapter on basic networking in any good "internet,how it works" type reference book. Or a good linux reference book, same chapter.

My host is not very busy. The loads on the sites are minimal. I want to use two services so that each virtual host I run can have individual SSL certificates to match.

Hi Bruno, I am NOT using apache in front of tomcat. Sorry. I really like standalone tomcat. So I would like to learn more about the first solution you described here. However, I do not understand it at all. What exacty do you mean, and where can I read/learn about it?

RE: 1 jakarta server + multiple ip's
Peter, I tried the solution you offered (below) about creating more than one service and using the address="xxx" parameter in the Connectors tags. It works great. However, what do you mean in your "disclaimer" that it is from the documentation and is untested? Did you mean to say NOT from the documentation? And if it is untested, but it is working, are there any reasons not to use it in a production server? Is it safe?

Re: Using more than one SSL cert in keystore?
Bruno, I am hosting a few sites on Tomcat standalone and they all share on SSL certificate because they all use the same domain name (they are just forwards to different directories). But now I would like to put up a new site that is completely independant of the others. It needs its own SSL cert and it needs four host names to all point to the same place and redirect to just one of the domain names so that the SSL cert will be valid, regardless of how the users chose to get to my site. Is it possible to do Virtual Hosting using IP's on a Tomcat standalone installation? Or will it only do the entries that I am already using? It would solve all my problems if I could. Then, to get four addresses redirected to one, I would simply have to set my default domain name set in server.xml, enter no other entries, and all the requests sent there would shift to the default domain. I am not sure if this scenario is achieveable. Tomcat may not even be set up for IP virtual hosting. One other thought--Is this more easily achieved by setting up a second instance of tomcat on my machine?

Re: Using more than one SSL cert in keystore?
In the (brief) interim between my asking the original question below, and now, I have found additional information--SSL must occur before HTTP handshake, and will therefore not work on hosts based on the same IP. I have more than one IP available from my ISP. I suppose the question would better be this: How do I cofigure virtual hosting of more than one SSL enabled host over ONE interface using multiple IP addresses?

Forwarding Domains
Is it possible for me to host somedomain.com on my tomcat, and as that is my prefered domain name format, and want all users who go to www.somedomain.com (YES, I have A records set up for both and they point to the same tomcat server) to be re-directed to somedomain.com, using my tomcat setup? In other words, I want to move all my users from the domain they enter to a domain I prefer USING my tomcat setup. I imagine there is some way to set up my server.xml to do it.

Personally, it seems like truly off-topic messages get tagged pretty quickly on this list. I think that's a reasonable solution to handle this problem. As for the *root* of the problem, the VAST majority of questions come from novice users who, predictably, don't know the difference between a "Tomcat" question and "Servlet/JSP" question. For most people, there *is* no difference. From that standpoint, it's artificial to say that some questions are "Tomcat" ones and others aren't -- they are all "Tomcat-related" and, as such, I feel like this is an appropriate place to address them. IMHO, asking a novice user to take it elsewhere would be a fairly cruel thing to do to an already confused and potentially frustrated user.

This is only done for non-compiled jsp files that are served by the JspServlet (mapped to *.jsp in the global web.xml). When the jsps are precompiled, the servlets they become are mapped in your own web.xml, meaning they are treated *exactly* like servlets and no date, compiling, or other shenanigans are done. How do most companies deploy their web applications? Do they include the source code for the jsps? Almost all of the companies I have worked for have been very protective of their source code and won't allow it to be released. I'm still not clear as to why you have to put your compiled JSPs in common/lib. I understand that some of your classes much be there, but why won't you split your classes into multiple jars? The "normal" way this is done is to precompile the jsps, bundle them into /WEB-INF/lib/myapp-jsp-compiled.jar, bundle the majority of your POJO to /WEB-INF/lib/myappcore.jar, and bundle your container service implementation classes (custom realms, valves, anything the main classloader needs) into /common/lib/app-container.jar.

Re: Delivering JSPs without source
Hi Steve, Hopefully I read your question right. There is no reason why your app wouldn't be able to find classes from a jar in common/lib -- there's something else going on here. Do you have duplicate copies of these classes anywhere? Do these classes rely on other classes found only in the /webapp/WEB-INF/lib jars or /webapp/WEB-INF/classes? This particular issue aside, there's no good reason why you should have to place your JSPs in common/lib. If there are other classes in your jar which have to be there (custom realm impl, for example), then break those out into a separate jar and keep your compiled JSPs in a separate jar in WEB-INF/lib. ... and if you find that your realm is being somehow implemented in the JSP, you know you're really screwed. :) justin At 03:32 PM 11/29/2004, you wrote: We have a web application that uses jsps.

What is the easiest way to monitor hits to resources (files or pages) on my tomcat 5 server? Do I write my own ticker into each page I want to monitor and store the incremented value to a database? Or is there a much simpler solution already implimented in some tomcat management software (I have never used any of the pre-installed software, and have actually been disabling it.

I meant to say that you could approximate the behavior you were asking for (dual response), but doing so would be hackish. How do other sites generate files on the fly (take it out of a database, or a report just run), on form submit, and send them down the line and not run into this problem? Like fzlists said, you'll see most sites load a page in response to a download request which either provides a link which the user can click on to download the binary content (right click, "save as" in IE), or that scripts the browser to automatically begin downloading. This is how CNet, Yahoo, and others do this. I see many people posting many places on the net that they are using the response to send a file, a lot of them are getting this IllegalState, but I never really found a followup solution that really fit my needs. Why would the possibility exist to push a file through the response if it leaves you with the ability to go nowhere after? If your browser submits a request and the response is a mp3 (through either URL inspection or Content-Disposition header), the browser will prompt the user to Save/Open/Run/whatever the file (and won't try to display it). Once the file has been saved, it will leave you at the original page from which the file was requested. Point being that after you push binary content through the response, it leaves you with whatever the previous page's options were ... there's really no contradiction in doing so. justin -----Original Message- From: Justin Ruthenbeck [mailto:[EMAIL PROTECTED] Sent: Monday, November 01, 2004 2:56 PM To: Tomcat Users List Subject: Re: Response and file downloads Luc, At 11:42 AM 11/1/2004, you wrote: >I am having a wee problem with using the response. > >I have a form on a page, with a submit button to download a file.

Re: request.getSession(false) randomly returns null in servlet
Mark,
Check the session id that is included in the request
(getRequestedSessionId) and verify that this sessionid is ALWAYS
identical to the one used when the session was created. More than
likely, you'll find this is not the case. If you're convinced that the
sessionid is found at one moment and not at another, try to find a way to
reproduce it and then post that to the list.
There's a 99% chance something is wrong with your code and/or the
client's response causing the behavior you're seeing. The fact that
you're seeing it with one particular servlet (presumably one type of use
case) makes it even more likely.

I do encode URL just in case, but Cookie is used on client

Re: [OT] Webapp upgrades and browser caching
Wade, Thanks for your comments. By adding the expires tag, it sounds like you setting the system up to schedule the upgrade. By this, I mean that you know you're gonna upgrade a week from today, so you configure Apache to suggest that all content should expire at that time. Sounds reasonable. In our situation, we have our webapps installed offsite in clients' facilities, so all/most of the upgrade process needs to be fool-proof... reconfiguring Apache 1 week (or whatever) before the upgrade isn't really an option. Aside from this, any more idea about how to handle this? Thanks, justin For static web pages you can use a tag like this: If the browsers still have a problem you might be able to configure Apache to output a header will all content called EXPIRES. I think you can if I remember right from some docs I read. You will have to look at Apache for that. I'm not sure about tomcat being able to handle that or not, but the apache bit should prepend the header I believe. The only other way would be to output all images and static pages from a servlet of some kind and add the header yourself to the request. Browsers should honor that tag or header for all images down the line from your html or jsp pages, but may not. Some browsers may be able to be set to ignore this all together though. Sometimes it is even worse than that. I have seen ISP's who think they are slick who install a cache in their systems, and they basically become a proxy for the users. If they are ignoring such things your users would have to contact them. I have seen some who do this for different protocols even http and https differently. That one irked me pretty good. Anyways, I use expires in all my jsp and html files. I haven't ever tried the other stuff for the headers from Apache, but think I remember reading about it in the Apache docs. I have output that header from servlets and ISAPI dlls before. Someone else may be able to offer more help.

I don't see any instructions with the COMMONS packages. Thanks for the quick directions in response to my problem. However, I am not familiar with the COMMONS project. I admit that I have a difficult time understanding how to implement other peoples programming in a way that it works with mine. I know how to use my own, because I wrote it. So I am at the stage in my programming 'carreer' that I need to learn how to tie in other work with my own. If someone could answer my fileupload Commons question directly, that would be nice.

How would I get a file off a remote users hard drive (which they specify by typing the file name and location into a text box in a form) to move to my server and be renamed (using my own file naming convention)? 2. How do you open a Browse File dialog box in a web browser (I would guess this would be easily done using Java Script. may not be an appropriate question here, so only answer if you happen to have the answer on hand) If possible, pointing me to a location on the web where this is done and the script is readily apparent, would be a fine answer. __ Do you Yahoo!?

Mainly because the case that brought up this problem is the tester using the File->New->New window command, then browsing to a bookmarked URL for the login page. They need to be able to continue using the old session in the old window, and the new session in the new window. Note that most browsers use the same cookie-set if you do a "File->New->New Window" command, but use a new cookie-set if you simply start them in another process (for Windows that means clicking on the icon again to launch a new browser instance). Try it with whatever browser you're using to test (varies by browser, but all that I've used have a similar way to accomplish this), but solving the problem this way would be much, much, much easier than asking your app to do something it's not "supposed" to do. justin __ Justin Ruthenbeck Lead Software Engineer, NextEngine Inc. justinr - AT - nextengine DOT com Confidential.

RE: porting to tomcat 5
Please note, these jsps and tag library were written on the servlet/jsp
2.2/1.1 spec, so I don't think this stuff was available at that time (I
maybe be wrong though).
Anyway, about the storevalue tag: it takes the value of the column in
the sql resultset identified by "transactId" and writes it to the output
stream. But this doesn't really matter, because if you look at the JSP
then see what tomcat generates, there's obviously an error in the way
Tomcat is handling this case.
In fact I changed the storeValue tag to our storeRowCount, which creates
a variable like storeValue except it stores the row count for the
results from a particular sql transaction. However I still had the same
result... Tomcat doesn't define the variable in the second if block.
Thanks for the help.

tag reuse, setParent and findAncestorWithClass
Hi, I'm upgrading our tag library to Tomcat 5 and having problems. Note that they were written back in JSP 1.1 and haven't changed for a few years. The problem looks like the tags are being cached and the setParent isn't being called for each new "reuse". As a result the wrong tag is returned from findAncestorWithClass when the WriteValueTag is re-used in a different nested block. Maybe this is how the spec was designed and I just don't know the right way to code the tags. Anyway here's what the JSP page looks like (note: transacttag issues a call to the database. Writevaluetag writes the value of a column from the data returned from transacttag. If 'transactId' isn't passed to WriteValueTag, it will use the findAncestorWithClass to find the enclosing IterateTag to determine the transactId): a - #1 - #2 - #3 - The problems: 1. UI_NAME in #1 is a column from the first "uis" transactTag. The writeValueTag prints out the value of this column but it shouldn't behave this way because it's enclosed IterateTag has a different "transactId". I put this here to demonstrate the problem 2. FORM_NAME in #3 is a column in the second transactTag of "ui". This column value SHOULD be output (like it has always done) because the enclosed iterateTag specifies the proper transactId, but this value is not output because it's parent is set to the first IterateTag and not the second, hence the different transactIds. #2 works only because I'm explicitly setting the transactId. The WriteValueTag extends the TagSupport class and everything is done in the doStartTag event. Please advise, -Justin
Re: Configuring Tomcat 5 to not display null value as word null
There is no Tomcat magic configuration parameter to make this
happen. Instead, take a look at HttpServletRequestWrapper. You can
combine that with a Filter to override the behavior of getParameter() for
the pages that need it such that it returns "" instead of "null" when no
such parameter value exists.
If you're unfamiliar with the above concepts, check Google, so see:
http://www.javaworld.com/javaworld/jw-06-2001/jw-0622-filters-p4.html
Good luck,

Hi,
I have the following JSP fragment:

The output of the page is

case 2 =

Is there any way that Tomcat can be configured to not display the word
"null" if the value is null? It is easy to replace the above example in
case 1 by case 2, but in my case it is not easy to make such change to
my existing code base (which I am migrating from another servlet engine
that outputs null as ""). I have pages with the
elements displaying the string "null" when there is no default value.

Re: How to keep a single user session from having multiple threads?
I'll answer your specific question, but first let me say: In the situation you are describing here, the root problem is not that the same JSP is being run concurrently for a particular session -- it's that your application has been designed such that you care. Mainstream jsp/servlet applications should be coded in a thread-safe manner such that data protection, locking, etc is provided in an appropriate way outside your jsp/servlet. Now, to answer your question: You cannot configure Tomcat to limit a session to one thread. What you really need to do is limit a single client (in a given session) from making two requests to the same JSP. Code your client this way, then add logic (in a filter, I'd suggest) to enforce the restriction. Doing this will work, but you'll find that you're swimming upstream against the spirit of the servlet spec, so keep that in mind. If your only concern is one of resource usage (that's what your email seems to imply), then you'd be better off trying to find out why your clients are making two simultaneous requests or (if it's a configuration problem), why you've got Tomcat configured to make that happen. If you want help with that, feel free to reply with more info to the list. Good luck! justin At 06:04 PM 8/19/2004, you wrote: Hello folks, I have a situation in which 2 threads are being started in the same user session. Now, that in itelf is not necessarily a problem - the problem it that both threads are executing the same JSP pages. This still does not hurt anything as yet,(The JSPs use session variables so that different users don't interfere with each other) but in the logs (using log4j) I can see the same JSP being executed by multiple threads simultaneously. There is definitely no need for this. I'd like to configure Tomcat such that it only runs one JSP at a time per user session. However, I am fine with having each user session start its own thread. Can this be configured in Tomcat (one session = one thread) or is this outside of Tomcat?

Re: How can I display number of requests over the past n seconds?
More academic exercise than recommendation, but... Write your own implementation of a Map/HashMap specific to java.util.Date objects. Identify your smallest time increment (5 seconds in your email). Identify largest time increment (60 seconds) Create (60/5)+1 buckets for your hash function Write your hash function such that each date object -- representing one request each -- gets placed in the right bucket. If the bucket contains "aged" dates, which you should know by simple counting (not comparison), empty it before placing a new one in. To display results, simply add up the content size of the appropriate buckets and return. This implementation is more lightweight than others suggested because the process of pruning is built into your implementation (instead of using external threads or comparisons each time you insert)... you're trading memory usage for decreased processing time. On the other hand, it doesn't *strictly* tell you how many requests came in the last X seconds -- only how many came since the last time unit started. It's also only reasonable for numbers like you suggested -- Tim or Yoav's suggestions would be better if your range is 5 seconds to 60 minutes, for example. justin At 07:10 AM 7/29/2004, you wrote: I need to display on a .jsp page the number of requests for Tomcat in the past 5 / 10 / 15/ 30 / 45 / 60 seconds.

At 12:13 PM 7/13/2004, you wrote: One option is to use a servlet that serves static files from directories and map that servlet in your web application's web.xml. This is nowhere near as robust or secure as putting httpd infront of your servlet containers. Again since this _could_ point outside the application directory it's a poor solution. This approach is what we've done to use shared resources (static content) amongst multiple apps. In some deployment environments, running Apache in front of Tomcat is a no-go for our customers, so implementing this way allows us to *optionally* use Apache: If Apache present, image is at http://www.site.com/images/a.gif and physically at /.../images/a.gif If Apache is not present, image is at http://www.site.com/webAppA/static?a.gif and physically at /.../images/a.gif Point being, implementing the serving as a separate servlet can give you additional flexibility at deployment time. The assertion that this diminishes robustness and/or security must be taken in context -- in many situations, this can be preferable to running with Apache in front. As always, YMMV. justin Otherwise (as in Carl's suggestion): You can "overlap" URI mappings to contexts.

It's genally a good idea to use the ROOT context as merely a redirection feature, _especially_ if you've got any possibility of naming conflicts (like you're suggesting). By this, I mean make your ROOT context simply do a redirect (either an HTTP redirect or a JSP/Servlet redirect, depending on what you need to accomplish) to your "real" default web application.

Re: Limit time for Database connection
Elisabeth, Robert's suggestion should work, depending on the particulars of your situation. Additional comments... If the problem is happening at connection creation time (ie initialization of the webapp), you're much better off. In this case, the network timeout isn't usually such a critical issue since someone is presumably monitoring the restart. If, however, your pooled connection is bombing out during normal runtime, you've got more of a problem. This situation is generally handled by the pool -- depending on which pool impl you're using, there will likely be a refresh rate which is the rate at which connections are tested for validity by the pool (seems like most people are using DBCP with Tomcat: see "testOnBorrow" and "testWhileIdle" parameters combined with "maxWait"). If you're concerned about requests to your app taking a long time because connections are no longer valid, this should significantly help and/or solve the problem. If that's still not enough and you feel you still need a shorter timeout, remember that there are tradeoffs to shortening the timeout (it's there for a reason, after all). That's going to be highly dependent on your pool impl and/or your database driver, depending on what you're using. Change your timeout settings there. Either way I'd advise only going as low at the DB driver and not messing with OS networking settings if possible. justin At 05:11 PM 7/8/2004, you wrote: Elisabeth, Nobody has responded to your question (that I've seen), so I'll "take a shot".

RE: jspc
There are a number of compelling reasons that pre-compiling JSPs are a good idea. Among the short list are: (+) Safety: If you precompile a JSP, you *know* before putting it in production that it will compile without problems. Why do we compile .java files into .class files before releasing a product? Because we want to make as sure as we can that the application will run as intended. (+) Source Code Privacy: Likewise, would your company release non-compiled source code for others to see? Why would you release uncompiled jsp source code for the world to see? (+) Speed: The first time a jsp is accessed, it must be compiled. Obviously, this delay degrades the user experience. (+) Security: Setting up your JVM to allow both execute and write access is a potential security hole. (+) Resource Usage: There is inherent overhead caused by the process of translating a jsp request to a servlet request (which all jsp requests become). To see this, look at a stack trace for a request that came through a JSP, then compare that to one from a Servlet. If you can avoid the overhead, why not? (+) Pre-compiling is a Deployment-time activity: Pre compiling doesn't affect developers -- it happens only at deployment time. Unless you change JSPs frequently (which won't happen is a best-practice production environment), there is no penalty to be paid by pre-compiling. If you care about these issues, pre-compile your JSPs. If you don't care, don't spend the 30 minutes it takes to figure it out. :) justin At 06:38 PM 6/24/2004, you wrote: Hi, Yes..that is what I thought, but I learned from a 'reliable' source I could accomplish this on saving overhead.

I see where your coming from, but if it's a business rule, it by definition belongs in the model layer. Remember, view is easy, the controller interfaces the two, and business logic of an application is the model layer. If you define the controller as the portion that *merely* interfaces the view with the actual working objects (ie a Command servlet), then yes. What I was trying to get at is that a DAO should be responsible for exactly that -- accessing the data. It is, IMO, ill conceived to use the DAO to determine whether a row is locked and therefore whether an item is available. That aside, I really do like your idea about kind of putting "a hold" on the class. I think that's a very good suggestion and a good model to follow. but in the end Justin, you would do well, I think, to do this in the database, i.e., have a "locked" field as write to it. The complication there is you'll need some method to unlock "abandoned" items periodically. I suppose my objection to handling in the database is not so much with the locks, but more with the combination of browsing behavior and inventory in a single table. Storing information about a user's cart in the database has its advantages -- namely sharing amongst machines in a cluster and persistence across restarts -- but anytime you have multiple hands (from multiple logical processes) in the cookie jar, I get nervous about maintaining integrity. Ultimately, I like Eric Earle's dual-table suggestion as it accomplishes both accurate, fail-fast inventory reporting for buyers, and separation of the browsing and buying data... along with the persistence and locking benefits of doing it in the DB.

Re: Design question ..
Since everyone else seems to have an opinion on this, I figure that I might as well share mine. :) A couple things to keep in mind: (*) Depending on your geographic location, you may have a legal responsibility to make sure that an item listed as available is, indeed, available. In other words, you can't tell a user that an item is available, let them put into their cart, then tell them it's not available when they try to pay for it. This is municipality-specific, but something to keep in mind for those doing cross-border sales. (*) The requirement you have described is a business-process requirement. It is not technical and therefore, IMHO, should not be satisfied with row locking, transaction manipulation, etc. Satisfy it on the controller level and avoid polluting your model with stuff like this. My personal inclination (which could change depending on the situation) would be to give users an X minute (logical) lock once something has been put in their cart. If they don't buy it (or indicate they want to keep it) after that time is up, it goes back on the shelf. In other words, treat everything in your inventory like a real object ... if a consumer wants to buy it, give them a pickup-ticket that they can take to the cashier. Ensure that the number of pickup-tickets equals the number of real items in inventory. The primary benefit here is that you'll fail fast instead of promising something that you can't deliver.

Lets take this scenario: User 1 and User 2 are trying to register for a course called "Taekwando". The fee for registering is X amount. Also there is another course called "Majagutamba" and it costs Y amount. Both theses courses have exactly 1 seat remaining. Now lets say user 1 adds both these courses in his shopping cart, and user 2 does the same, since user 1 has not completed his transaction and paid the enrollment table wont have an entry for user1. (The Enrollment table keeps track of which user is enrolled in which course). Therefore both users have both those courses in their shopping carts. Now both of them proceed to checkout. They enter their credit card information and say submit. Both those users make payments and get enrolled for both those courses!!! Which is wrong , since both those courses could only enroll 1 more person, instead two new users were just added. To avoid the above problem one could implement a singleton synchronized Transaction object that would process shopping cart checkout in a queue. The problem with this approach are: 1. If anything goes wrong with any one transaction, it would hold up the entire queue. (Well we can have some sort of timeouts and take care of that.) 2. Since this is a syncrhonized singleton and if the traffic for registering for the courses is high, this would be a slow process for which the user will have to wait.

Re: Is tomcat a suitable server for our application ?
Can Tomcat handle 3000 concurrent sessions? Yes. The bottleneck will not be Tomcat, per se, but rather either hardware resources (memory on the heap) or database connections. What you really need to figure out is how *active* those 3000 users will be -- 3000 users actively querying financial data reports is VERY different than 3000 users reading today's news reports. Point being that the question to ask is not whether Tomcat will support 3000 concurrent users. This is a question of resource availability. The question should be: can my one machine running with MY APPLICATION, Tomcat and the hardware specs you gave support 'X' simultaneous requests with a minimum/average request processing time of 'Y' milliseconds?

Re: Maintaining Sessions
That makes sense. I did some reading since you replied and I realize now that I can have more than one connector per engine containing multiple hosts. That also explians the mysterious redirect port parameter that I couln't make heads nor tails of till now. But a few web.xml questions. There is a web.xml file in my catalinahome/conf directory. I have read that according to some specifications somewhere, I should also have a web.xml in every WEB-INF directory for each application. Does the main web.xml file apply to all applications, and the WEB-INF web.xml just add settings to the specific applications, or does it OVERRIDE the main web.xml (so I would need to include ALL the entries found in the main file in ALL of the application level web.xml files)? And what would an entry look like to force one specific file to re-direct to the secure port? I can only find very vague examples that secure entire applications.

Re: Maintaining Sessions
Hi, Square peg, round hole. It seems like the only reason you've split these into multiple hosts is to differentiate between secure and non-secure communication -- that's a bad idea. From what you've said, the best approach is to put all of the JSPs for (A) and (C) in the same webapp, but set s for those resources (C) that require https. See: http://jakarta.apache.org/tomcat/tomcat-5.0-doc/ssl-howto.html What you're describing here is a deployment-time problem -- it shouldn't impact your code in a major way like distributed sessions would cause. justin At 02:56 PM 6/2/2004, you wrote: Hello, I am running Tomcat 5.0.25 on SuSE Linux 9.1.

Re: JSVC to run tomcat?
I rechecked my configuration file, and I was using to JSVC script for tomcat 4 which loads a different class than the tomcat 5 script. I corrected the class and it works flawlessly. There are always TWO JSVC processes running. Is that normal? And can somebody please explain exactly what is happening with JSVC and tomcat. How do I know the process is actually running with the underprivelaged user account? If JSVC runs tomcat as a Daemon, does it shut off when no services are requested from it and start up again when a service is requested? Will this slow down my system?

JSVC to run tomcat?
I am very impressed with the responsiveness of this list. I appreciate all the help everyone has given me in learning about JSVC for running tomcat as an underpriviledged user on ports 80 and 443. However, I am still running into a problem. I created a tomcat user and group and all tomcat files and web application files are owned by tomcat. I compiled the jsvc and set my scripts to run jsvc with the proper options (I believe), and when I run the script, I get nothing but my prompt back. I run ps -ax and jsvc is NOT a running process. What am I doing wrong? I run the command from my /tomcat/bin: jsvc -Djava.endorsed.dirs=../common/endorsed -cp ./bin/bootstrap.jar -outfile ../logs/catalina.out -errfile ../logs/catalina.err org.apache.catalina.startup.Bootstrap nothing I run the command with the user option, (as in the scripts) again. nothing.

RE: API for authenticating user
Koji, (1) Make sure you understand the implications of directly using any of Tomcat's internal classes (such as o.a.coyote.tomcat5.CoyoteRequest) -- especially to circumvent intended security. It is rarely advisable. If you still want to use it, move the class and/or jar into the $TOMCAT_HOME/common/classes or $TOMCAT_HOME/common/lib directory. It will be accessible to both Tomcat and your webapps in this case.

RE: standalone production?
I am intending to run in a fully internet exposed environment and I only have ONE physical machine to use for deployment. It will be directly connected to the internet at co-location service provider. So ... In a conversation from yesterday, it appears another user had a similar question. How to run on port 80, securly. Is it possible to run tomcat with a non-priviliged user? What is this JSVC approach they referred to, and what is the solution that was given? Where can I go to read more?

standalone production?
Is it considered safe to run tomcat as a stand-alone production server on ports 80 and 443? This requires tomcat to run as root (or so I have read) and it is therefore "not recommended". Using apache forks child processes that run as nobody. But I don' want to use apache. Again, is it safe to run tomcat as a stand-alone production server on port 80 and 443 as root? Or is there some way to deny root permissions and still use these ports? __ Do you Yahoo!? Friends. Fun. Try the all-new Yahoo!

Alas, my customer's deployment platform is windows. So

So Tomcat does it all!

My client is a publisher, and the bulk of the site will be many

The HTML content, however, will be served by tomcat, since
it has some dynamic components.
The biggest question, then, has to do with your security requirements.
Specifically, does this content need to be protected or can it just
sit out there for anyone to grab?
If it need not be protected, this is, IMHO, a textbook example of when
to use Apache. You've got a large collection of static data and a
relatively small web application associated with it. You've probably
got different groups working on the different parts (the publisher's
content and the HTML pages), so it makes sense to separate it out and
serve the static content by generating links to your static web server's
content from your dynamic HTML. Additionally, you could then put the
two pieces on separate machines (one or more with Apache, one or more
with Tomcat) to keep them separated even more cleanly.
If the content needs to be protected, I would create a separate
directory and put the content there. Symlink this to the base of your
Tomcat webApp and let Tomcat serve it normally, employing whatever
security scheme you're using. You won't be able to deploy the entire
thing as a single WAR, but it doesn't sound like you really care to
do this anyways.
This is why it's not practical to bundle everything into a war file.
Instead, I need tomcat to point to the file system where many
users will be building the site.
On the other hand, the war file can easily contain the java
infrastructure
(struts, velocity, configuration information, etc.). I'd like to be able
to keep the small war file, hot deploy, etc., but have the raw content
(static and otherwise) live elsewhere.
Given that, would you solve it with multiple contexts? Or do you
have another suggestion?
Alternately, you could extend the DefaultServlet (if you don't mind tying
yourself to Tomcat and your version) with your own custom static content
servlet that gets data from an arbitrary directory. If you can't be
tied to Tomcat, use the source as a base to write your own default
servlet. This solution is more on the "slick" side of things, so it
wouldn't be preferable ... better to stay within the mainstream
boundaries.
If you can, look into symlinking or Apache. Consider the extend/impl
DefaultServlet idea. If you're still not satisfied, having two
separate contexts can be made to work. Perhaps others have additional
ideas.

Of course, there are many ways, none of them advised. You want to keep
your webapp as a whole, that's the whole point of a WAR file. You can
symlink (at the filesystem level) or use normal HTTP linking to access
your static content. But you can't symlink in a WAR, so...

And I agree with Justin, just to be clear. I wasn't advocating
anything
different from what he said, just showing you that it can technically
be
done. If crossContext forwards are the worst design choices on this

If you can, look into symlinking or Apache. Consider the extend/impl
DefaultServlet idea. If you're still not satisfied, having two
separate contexts can be made to work. Perhaps others have additional
ideas.

Of course, there are many ways, none of them advised. You want to keep
your webapp as a whole, that's the whole point of a WAR file. You can
symlink (at the filesystem level) or use normal HTTP linking to access
your static content. But you can't symlink in a WAR, so...

And I agree with Justin, just to be clear. I wasn't advocating anything
different from what he said, just showing you that it can technically be
done. If crossContext forwards are the worst design choices on this
list, we'll be in great shape.

Re: forwarding across contexts?
At 07:04 PM 5/10/2004, you wrote: Hi, I'm trying to install a filter into the default context that forwards to my application (in another context) and it doesn't seem to want to work. (jboss 3.2.3 with embedded tomcat 4.1.29) In researching this, I've seen various hints that this may in fact be illegal. Can anyone confirm? It is generally good design practice to limit interactions between your webapps except for strongly defined specific interfaces that promote modularity. Doing something like you're suggesting will likely lead to messy, difficult code to work with ... not because it's a necessarily bad design idea, but rather because the premise behind J2EE is that code bases are designed, coded, deployed, and maintained as independent applications. They're not meant to ineroperate in a fluid way. It's possible to do what you're suggesting, but not recommended. The REASON I want to do this is that I want to be able to take advantage of "simple" URLS with the default context, as in "/images/whatever.gif", and have them be served by DefaultServlet, which conveniently knows how to handle all that sort of stuff, set mime types, etc. I'm also hoping that DefaultServlet was written by someone more clever than me! Resources need not be within the ROOT web application to be served by the DefaultServlet. You'll notice that the DefaultServlet is defined within the global web.xml (I haven't worked with recent versions of jBoss, so I'm not sure exactly where they put this these days), which means that all applications inherit it. This means that resources like "/images/whatever.gif" and "/mywebapp/images/whatever.gif" will both be served by the DefaultServlet unless you configure it otherwise. But, I also want to capture certain "simple" URLs and forward these to another context. As in "/protected.html" needs to be forwarded to "/accesscheck/protected.html" or similar. Am I on the wrong track here? Is it possible to forward (via RequestDispatcher) from one context to another? If not, how can I take advantage of DefaultServlet in my application? See ServletContext#getContext(String). Again, I predict you'll find this to be a clunky and frustrating way to do things. Unless you have an over-riding reason to do otherwise, embrace the idea of separate and distinct web applications and let the container do this URL parsing and forwarding for you.

startupw.exe & classpath
I'm having classpath trouble when I start Tomcat 5.0.19 with the "Start Tomcat" shortcut that points to "C:\Tomcat50\bin\tomcatw.exe //GT//Tomcat5" I want to include a directory that is outside of the tomcat install dir, e.g. "c:\mydir", but I don't know how to add that directory to the classpath. I can edit setclasspath.bat to include that directory, and then start Tomcat with either "startup.bat" or "catalina.bat" and it works fine; is there an analogous file for tomcatw.exe?

Re: FW: Tomcat stops loading when I run my servlet with
At 05:21 PM 4/23/2004, you wrote:
Justin,
I followed your advice immediately, but the exact same thing happens.
My response was tongue-in-cheek, but that's ok. :)
Just to restate the issue, my servlet hangs because it needs to obtain an
XML Schema from localhost:8080. But it can't get it, because Tomcat won't
finish loading until the servlet is finished. But the servlet won't
finish
until Tomcat finishes loading. Etcetera, etcetera ad infinitum.
I've got some sort of logic issue here. If I want to kick off a program
that polls a directory for XML files, should I probably do something
where I
kick off an independent thread, so that Tomcat is not waiting for my
program
to finish (which if it's a good poller, it never will)?
Ah, I see. Using the ServletContextListener will make your life easier
going forward, but it doesn't directly address what you're talking about
here. As others have said, you may be able to solve the immediate
problem with an EntityResolver (pretty standard). The larger question,
though, remains.
Since there's no standard way to make a webApp unavailable after it has
been fully initialized, whatever resources you need to verify the startup
have to be available during the contextInitialized() timeframe. That
means your options for deployment are a tad limited (ie where to place
these schemas), regardless of whether you use an EntityResolver or
not. It's really an issue of what types of restrictions you're willing
to place on the deployment ... if it's always deployed as an exploded
dir, you could use a init param to specify the OS filesystem location of
the schema (or an EntityResolver). If you can put the schema somewhere
in the webapp or container's classpath, you can use the
getResourceAsStream() method.
If you truly need to poll indefinitely for XML files (files will change
during runtime), but reading one of them isn't required for you to start
the context successfully, then you could fire off the thread and let your
startup finish gracefully.
Just depends on the other conditions of your app.

Regards Roger If anyone has insight into this, I'd be very curious to get a definitive answer. Although I've never explicitly explored this (or read this part of TC's code), it seems like Tomcat reads the entire POST, makes an in-memory copy of it, then passes it along to the Servlet/Filter processing the request. If this is the case, then the InputStream from the ServletRequest is not reading data across the network. Again, my reasons for surmising this are anecdotal. It seems like it'd be easier and more fault-tolerant to have the above behavior than to truly stream data over the network. Any authoritative input would be appreciated.

Re: How to limit concurrent requests by same user
You'll find quite a bit of info about this in the archives. When this has come up in the past, consensus seems to have been the setting of a unique token within the page when generated such that each time a user requests a "submittable" page, that page will contain a hidden attribute with that token. Implement a filter that only allows processing of that token once. The problem with the solutions mentioned in this thread is that if a user double clicks on a form, the browser will display the output of the second click (which would be "nothing"). If you implement the tokens, the second request can wait for the first to complete, observing a result object that it can return once the first request finishes. This is *definitely* an advanced technique, but it's the most robust, user-tolerant, and resource-conservative one I've used and/or seen other places. Depending on your situation, the simplest way I've seen to (mostly) handle this is to disable the submission button with Javascript once it's been tapped once. It's a point solution that's not perfect, but it'll catch 98% of egregious offenders. justin At 12:58 AM 4/21/2004, you wrote: > I wonder if it would be possible to write a filter that would implement > this functionality transparently to the JSP pages/servlets.

Re: Port-per-webapp?
Tony, Can you include your full uriworker.properties and worker.properties files (inline in the email) for us to look at? Be sure, of course, that the files you're editing are indeed the ones being read -- for example, make sure that by removing /examples from uriworker.properties, IIS no longer serves the Tomcat examples. If there's something wrong with your config files, we should catch it pretty easily. justin At 01:20 PM 3/16/2004, you wrote: Hi Justin, Thank you very much for your input (and it's nice to know that my email is actually getting distributed). I've looked extensively at the documentation for days now, and I cannot figure it out. The problem I'm having is that the forwarding is "selective". I have two webapps: "webapp1 and examples" that are correctly forwarded by IIS but not the ones that I deploy. In order to test it, I simply copied the "examples" to "examples2" and added the following lines to uriworker.properties: /examples2/*=ajp13 where ajp13 is my worker name that is defined in the worker.properties file. I get 404-file not found error- when I try to access http://localhost/examples2/, but it works if I rename "examples2" to "examples". So it has to be some configuration error, but I just can' t seem to find out which configuration. Any suggestion helps, thank you!

Re: Port-per-webapp?
You have to configure the IIS plugin to path-forward URLs that have your webapp name in them. I don't use IIS, so I don't know specifically how it's done, but it's basically a way of telling IIS that anything matching "my.server.com/myApp" should go to the connector instead of being served by IIS. You can test to make sure that this is your problem by adding a file to IIS's doc root that matches the url that is supposed to go to Tomcat. If you get the page served by IIS, then your forwarding isn't working (alternately, the 404 page should indicate whether it's coming from IIS or Tomcat). Look at the connector docs -- I'm sure the specific files/steps are in there... Or perhaps an IIS user will respond here. justin At 01:04 PM 3/16/2004, you wrote: Does anyone not know anything about this?

Re: delaying context reload
Cindy, If this is a problem for you, turn reloading off in your context.xml and use the manager app's Reload command instead. This command can be executed either through hitting a URL, using the manager html pages, or (best) through an Ant command. Doing this means the reload only happens when you request it. It's a standard way to do things. Alternately, change the interval at which reload checks happen (I don't use this, so I don't know where this is set). If you double the reload check time, you should halve the number of time you have the problem (and double the average wait for a reload). In short, use the manager. :) justin At 09:23 AM 3/16/2004, you wrote: At 08:00 PM 3/15/04 -0500, Christopher Schultz wrote: >Run Plugin:"c:\eudora\attach\Re delaying context reload.ems <0880.0002>" > Hi Chris, No, I'm not using Ant (yeah, yeah, I know I should...) This is my local development machine where I have WEB-INF/classes set as my output directory when I compile. This has worked fine, but as things have become more complex the server reload has started to beat the compile. I was just hoping to find a way to delay the reload a few seconds. Since none of the responses I recieved offered a solution, I guess I should assume that this is not possible with this version of Tomcat. BTW.

Strange cross-context bean/session behaviour
I have an internal website, split into several web applications. A problem has been co-ordinating a UserDataBean across the sessions for each app, so that the user's preferences change across all apps simultaneously. Here's the tag that puts a UserDataBean into the session; it's at the top of all pages: The body should be executed only if there is no bean attached to 'user' in the session, and that's what appears to happen. The co-ordination problem was solved by having each bean register itself with a singleton that dispatches propertyChanged events to other beans for the same user. I created a reporting function for the singleton to inspect it, and got this: Number of UserDataBeans listening: 3 Listening sessions: 89140B58A732CF2989E5F3D9D7D58AA3 [Intranet] 1E8628A77789A26C49AB80AA3B0B8665 [Project Template] 1E8628A77789A26C49AB80AA3B0B8665 [Intranet] [Intranet] is the contextName of the root app; [Project Template] is the name of the app that is a template for other apps. Notice that there are three beans, but only two sessions. The session starting 8914 is initialized on hitting the home page, and a bean is created for it. The session starting 1E86 is initialized on first hitting the template app, and a bean is created for it. My question is about the second bean created for the session starting 1E86. Every page uses to grab mainMenu.jsp from the root context; mainMenu has the same tag as I listed above. What's apparently happening is that, since the import is cross-context, mainMenu is being processed as being in the root context, not the template context (as it should be, I believe). However, the session to which that bean is attached is the Template session. In other words, the template session is going cross-context. At the point the import is executed, both sessions already have a UserDataBean attached to 'user' in the session. So why is a third created? In either session, and in either context, the bean is already initialized and attached. The index page of the root app also imports mainMenu.jsp locally, but doesn't create a bean in that case (the order of the beans above is necessarily the order in which they were created; the third, unnecessary bean was only created after the cross-context import). This isn't a problem, per se, just a strange behaviour that I would like to understand. Any insight is appreciated.

Re: java.library.path question???
Some hints to get you there...
Think about how you start Tomcat (assuming it's not as a Windows
service). If you were to edit that startup script to add your dll
location to the java.library.path, then it would be available when you
run. If you're running with low-level tools, this will be
straight-forward. If you're running with an IDE, it'll be a tad more
complicated (like everything else).
