Strange behavior of Tooltip when used with JComponent with in Applet
I have a problem with a JComboBox placed in an applet which is having a ToolTip text set on it.

realm in context in war file
Has any of you tried defining a realm inside the context.xml taken form META-INF file from inside the war file? I have the following context definition: context path=/test1 override=true docBase=webapps/test1 realm className=org.apache.catalina.realm.MemoryRealm debug= pathname=webapps/test1/META-INF/context-users.xml / /context but the realm definition is simply ignored by tomcat. Any idea why? Thanks in advance, Michal. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Automatic redeploy based on web.xml contents
I'm using Tomcat 5.5.9 with Tapestry and Spring. Given my usage of Spring, I've found that I need to reload my project on occasion to pick up new XML configurations. To this point, I've accomplished this by writing a simple Ant script that simply touches my web.xml file. The file update triggers Tomcat to reload my project. However, after doing some JNDI / JDBC setup in my server.xml, my update-the-web.xml-file method of reloading my project quit working. It still works when I manually reload the project through the Tomcat Manager, though. I back-tracked far enough to find that the mere presence of the Context node pointing to my web application causes the reload to stop working - even when I have reloadable=true set on my Context node. I remove that context node pointing to my web app, and the reloading starts working again when I touch my web.xml file. Can anyone fill me in on why this is so? Is there a setting whose default is getting wiped out when I use the Context node in the server.xml file for my web app? Am I doing something wrong to cause this behavior? Is there something far more sinister going on here? :) Thanks, Paul Kimbrel
Cannot build Tomcat 5.5 using Ant
Hello, when I tried to build Tomcat 5.5 using Ant 1.6.2 and the packaged build-file, an error occurred telling, that Ant was unable to expand file.zip and that there has been an error in the build-file. I have tried several versions of Tomcat 5.5, but it does not work. Anyone having the same problems?
Java 1.4.2_08 and up breaks Jstl
Hi All I have found a Bug in Java 1.4.2_08 and Java 1.4.2_09. Goto this address to read about it: http://forum.java.sun.com/thread.jspa?threadID=599301tstart=0 The new versions will break your jstl code and create errors in the log and create blank pages. I have tried a new Tomcat version, no luck. I had it running on another server but that server is running on Java 1.4.2_05. So just a tip. Dont install Java 1.4.2_08 or higher. It will kill your application if your using jstl. Martyn - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Has anyone used Tomcat 5.5.9 connecting to MS SQL Server usin g JNDI?
David, Thanks for the link. I have followed the instructions but unfortunately get similar errors to what I had previously I am afraid. In a situation like this I am sure I could get the company to pay for some support for this type of problem, but I am unsure who would be best to help with this. Without further help, I will have to sideline the upgrade to 5.5, until there is more info out there for the connecting using JNDI with a MS SQL Server example. In my opinion the people who develop Tomcat should provide an example of JNDI for ALL major databases. This is one of the things that makes the Tomcat offering lacking somewhat in maturity. It seems to me it is relatively easy to get the basic JSP / Servlet stuff up and running in no time, but it has always been a hassle to get JNDI to work in Tomcat.

Does Tomcat 5 support mod_JK?
Hi, I am trying load balancing with Tomcat 5, fornted with Apache's mod_jk connector. It is always the local one that serves my request. Cannot get my remote Tomcat to serve any. http://localhost/jkstatus also gives a error page Have workers.properties and all configured but ... Doing a search on google found Tomcat + mod_JK documentation take me to Tomcat 4.0.1 docs (http://jakarta.apache.org/tomcat/tomcat-4.1-doc/config/jk.html) Tomcat 5 docs has almost nothing on mod_JK (The page http://jakarta.apache.org/tomcat/tomcat-5.0-doc/config/jk.html is NON existant) Am I trying in vain. DOES TOMCAT 5.x.xx support mod_JK or vice versa. I am using Tomcat 5.0.28 and mod_JK binary - mod_jk-1.2.14-apache-2.0.54.so OS: Windows XP any clues will be appreciated. thx g1 _ Is your PC infected?

RE: Has anyone used Tomcat 5.5.9 connecting to MS SQL Server usin g JNDI?
Alistair,
For configuration purposes I attach the Context.xml, web.xml and
mininPCO-practise.xml - which is the web application file which resides in
TOMCAT_HOME\conf\Catalina\localhost directory.
The error message is basically Cannot create resource instance. (Full
Error message attached below.)
The Java code above works in 4.1.31, so I am not really worried about this,
unless Tomcat 5.5.9 works differently.
Here is the code snippet from the java class PortletHelper that is being
executed which produces the error at the end of this email.
Well I think that is all that anyone needs to check out my app.
If anyone can offer some good advice on this, it would be much appreciated.
Best Regards,
Ian

RE: Has anyone used Tomcat 5.5.9 connecting to MS SQL Server using JNDI?
Hi,
You can only configure a web application in 1 place. You can't use *both*
context.xml AND a webappname.xml. I think the
TOMCAT_HOME\conf\Catalina\localhost method is tried first, and because this
does not have any of your datasources in it you get your problems. Decide on
either TOMCAT_HOME\conf\Catalina\localhost\webappname.xml or
META-INF/context.xml and see if you get any further first.

RE: Has anyone used Tomcat 5.5.9 connecting to MS SQL Server using JNDI?
Hi,
A) First, can you clarify which method you have opted for now of;
1.
TOMCAT_HOME/webapps/webappname/META-INF/context.xml
or
2.
TOMCAT_HOME/conf/Catalina/localhost/webappname.xml
B) Ensure your database JAR(s) are in TOMCAT_HOME/common/lib (not in your
webapp lib).
C) Try something simpler ...
DataSource dataSource = null;
try {
Context ctx = new InitialContext();
dataSource = (DataSource) ctx.lookup(java:comp/env/jdbc/UKportalPool);
} catch (NamingException nE) {
log.error(nE.getMessage());
} catch (NullPointerException npE) {
log.error(npE.getMessage());
}

Alistair,
Well I have learned something that I was doing wrong, but
after removing the
webappname.xml I get the same error.
Any more ideas?

Hi,
You can only configure a web application in 1 place. You
can't use *both*
context.xml AND a webappname.xml. I think the
TOMCAT_HOME\conf\Catalina\localhost method is tried first,
and because this
does not have any of your datasources in it you get your
problems. Decide on
either TOMCAT_HOME\conf\Catalina\localhost\webappname.xml or
META-INF/context.xml and see if you get any further first.
Cheers, Allistair

Alistair,
For configuration purposes I attach the Context.xml, web.xml and
mininPCO-practise.xml - which is the web application file
which resides in
TOMCAT_HOME\conf\Catalina\localhost directory.
The error message is basically Cannot create resource
instance. (Full
Error message attached below.)
The Java code above works in 4.1.31, so I am not really
worried about this,
unless Tomcat 5.5.9 works differently.
Here is the code snippet from the java class PortletHelper
that is being
executed which produces the error at the end of this email.
Well I think that is all that anyone needs to check out my app.
If anyone can offer some good advice on this, it would be
much appreciated.
Best Regards,
Ian

Re: Max thread/session timeouts
Peddireddy, how about your project? I have finally found a solution here ;-) If the database handles requests faster, the load on my Tomcat(s) are lower, because of the lower count of active threads. This does not resolve the problem induced by the apparent connection limit on Windows 2003 Standard Edition, especially in peak situations with ~3000 active Threads. I've got the computing centre to install Red Hat Enterprise 4 on one of the servers and voila, the errors are gone! Admittedly, it seems that Linux is a bit slower when getting into a high thread count, it's sufficiently fast for my project. Also, it seems faster on low thread counts (500). A simple servlet building a XML tree (without any database access or other 3rd party access) runs about 30% faster on Linux than on Windows on the same machine. I think the slower response of Linux with high thread counts is induced by a slower thread handling. An engineer from Red Hat will try to optimize that tomorrow.. -- Michael On Fri, Jul 22, 2005 at 11:23:24AM +0200, Michael Kleinhenz wrote: Peddireddy, your mail is very informative. we have a very similar set up (4 Xeon processors 3.5 GB Ram and WIn2003 Standard edition) and hardpart is that we cant change this setup and switch to Linux. same problem over here. The computing centre of our client can't provide Linux servers. I'm struggling with this problem for 3 weeks now. I heard about clustering on diferent boxes. Is the process of running multiple tomcats on a single machine will be same?? My experience was that with a single Tomcat on a large machine, you'll never use that box fully. Besides that you can't get the Sun JVM to accept a large amount of threads while giving them enough memory, Tomcat seems to have performance problems with 3000+ threads busy at the same time. The BEA JVM (JRockit) performs better in terms of memory and threads but is slower than the Sun JVM. If you have rather complex database operations performed by your webapp, this will get you into trouble, because if there is a single bottleneck in the whole system, the requests will pile up in the server, it hits its thread limit, and ceases operation. So, I have made good experiences with 4 Tomcats on a 2xXeon with 4GB. The server's load is somewhere between 70% and 100% while running with high load and can handle more concurrent requests than a single Tomcat. You talked about some workarounds using esoteric registry keys, can you eloborate on this or tell me where I can get details about it and the details about limitations placed by windows2003 on a single process in terms of number of threads, memory etc. We use 2003 Standard Edition and get the following limitations: . Windows only provides 2GB memory to all applications running, regardless of how much memory you have. All other memory is used for Windows itself. With a registry key, you can extend this to 3GB. I don't have the key handy, but it can be found in MSDN. . The somewhat larger problem is the crappy TCP stack on Windows. A single Tomcat easily handles 1000 concurrent connections, but if I start 4 Tomcats, I get a WSAENOBUFS error (An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full) at about 3300 concurrent connections. Because each Tomcat runs with his own instance of the JVM, I suppose the problem is Windows, the network or anything else that is used by all Tomcats at the same time. Even worse, after such a crash, there is a 10% chance, the Tomcats not resuming normal operation but crashes completely. . Windows has a default limit of 5000 ephemeral ports that can be used fo outgoing connections. This can be changed with the MaxUserPorts registry key. Also, the TcpTimedWaitDelay key is relevant for network performance. Both are described here: http://msdn.microsoft.com/library/en-us/randz/protocol/tcp_time-wait_delay.asp I'm now really irritated by this problem. I need a capacity of about 15000 concurrent connections for my project. I also have 3 2xXeon servers here, but windows (or anything else) doesn't allow more than ~8000 connections until it dies. -- Michael -- Dipl.-Technoinform. Michael Kleinhenz tarent GmbH .

Re: adding mime-type
If you are calling it though a servlet I believe you will still need the set the MIME type in the HttpResponse object with a call like response.setContentType(text/html); I am not sure how you would do it for a JSP page. Unless you just went for the inelegant option of % response.setContentType(text/html); % You would clearly need to replace text/html with the MIME type you set up already.

Configuring webapps (or, bean access in ServletContext and JSP?)
Hi list! Long time lurker, first time poster. I've been trying to
figure out how to do this all day and it's driving me crazy. Any help
greatfully accepted! Also, apologies for this being slightly OT --
it's more about J2EE in general than Tomcat. If anyone knows a decent
J2EE mailing list they could point me to I'd be very happy, but I
couldn't find any after googling for a while, and you folks all seem
to know so /much/.
I have a webapp that has a single JSP page. The JSP page scrapes data
from two remote HTML pages and presents it. This scraping needs to
only happen on demand (i.e. when the page is loaded) and at most every
NNN seconds (it's a monitoring app and I don't want it to turn into an
accidental DoS!)
The scraping itself is done by one Bean object for each remote source.
These looks a bit like:
(Please forgive errors in my code snippets, I'm rewriting them in
Gmail's compose box so there might be small syntax problems)
===
abstract class Scraper() {
public abstract void doScrape();
protected URL url;
public void setUrl(String url) {
this.url = new URL(url);
}
protected scrapeIfNecessary() {
// check a timeout; if we haven't scraped in the last
// NNN seconds, then:
doScrape();
}
}
class ScraperOne() {
// ideally I'd like a one-arg constructor with the URL in, but I have to
// make this class a bean for the JSP page, so no-args it must be
public ScraperOne() {
super();
}
private String dataOne, dataTwo;
public void doScrape() {
// loads from this.url
// puts results in dataOne, dataTwo
}
public void getDataOne() { scrapeIfNecessary(); return this.dataOne;}
public void getDataTwo() { scrapeIfNecessary(); return this.dataTwo;}
}
// ScraperTwo is similar
===
Now, up until now, I had lines in the JSP that looked like this:
===
jsp:useBean id=data1 scope=application class=foo.ScraperOne
jsp:setProperty id=data1 name=url value=http://www.foo.com/foo.html/
/jsp:useBean
pI got data ${data1.dataOne}.
===
Now, however, I want to move that URL configuration out of the JSP and
into a config file. Thing is, I'm not really sure on how I'm supposed
to make a webapp read a configuration file on startup then make that
config available to all objects that need it. In the past I've done
this with a load-on-startup servlet and a Singleton to store the
config, but I know that's a bit of a kludge.
After some research and messing about, I've created an implementation
of ServletContextListener that can read an XML file, create an
instance of my ConfigurationBean class, then put it in the context
with:
ServletContext.setAttribute(config, myConfigurationBean)
My first problem with this is when I use it in my JSP:
jsp:useBean id=config scope=application class=foo.ConfigurationBean/
I get this error:
===
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: 10 in the jsp file: /index.jsp
Generated servlet error:
/usr/local/jakarta-tomcat-5.0.29/work/Catalina/localhost/foo/index_jsp.java:51:
config is already defined in
_jspService(javax.servlet.http.HttpServletRequest,javax.servlet.http.HttpServletResponse)
foo.ConfigurationBean config = null;
===
It looks like the jsp:useBean tag is trying to declare another
application-scoped ConfigurationBean. I would have expected it to read
in the one declared in the ServletContextListener instead. What have I
misunderstood?
My second problem: assuming that I get the ConfigurationBean correctly
set up in the JSP, what is the best way to pass the appropriate values
through from it into the DataOne scraper? Is it just with a Java
snippet in the JSP, or am I missing a trick? Something like this:
===
jsp:useBean id=data1 scope=application class=foo.ScraperOne
% data1.setUrl(config.getDataOneURL()); %
!-- or maybe --

With JSP2 though I thought we would be avoiding Java in JSPs like
this... is there a simple way to pass arbitrary values out of an
application-level bean and into arbitrary Java classes?
Sorry for this rather exhaustingly long post. Again, any suggestions
will be very greatfully received. I'm sure this whole configuring
webapps thing must be well discussed somewhere but I've been googling,
searching JavaWorld, developer.ibm.com, sun.com etc without ever
finding a clear, easy do this, then this type guide.

RE: tomcat and active directory
It looks like you are configured for anonymous bind.
By default, the AD LDAP implementation does not allow anonymous bind. You
have two ways of handling this:
1. Configure your AD tree to allow anonymous bind. Essentially, you will
need to create an ACL against the appropriate object (container) in the
tree.
2. Create a low powered user that has read access to the directory tree
and configure the realm to bind as that user..

OT: JSTL and JSF book recommendations
We're using Tomcat 5.5.9, and I'm looking for good books (or other resources) for learning JSTL and JSF. These will be for a person with a novice-level understanding of Java and Tomcat, so I'd like something that will take him from beginner to intermediate (or better). He'll be learning Java at the same time. Any suggestions you have are appreciated.
Re: OT: JSTL and JSF book recommendations
Starting out, I suggest the Core Servlets and JavaServer Pages by Marty Hall to gain an understanding of the Java EE web technologies. It's about as good of a book as I've seen on any technical subject matter, particularly for a beginner. I still reference it after several years. For JSF I have both the O'Reilly book and the Core JSF books. I wouldn't say one is particularly better than the other, but both need a working knowledge of underlying technologies to make total sense. I have the first editions of them both though, so they are a bit behind the game on the latest and I believe second editions on each are available. I also suggest going here http://forum.java.sun.com/forum.jspa?forumID=427 it's the official JSF forum, you'll get lots of information from it.

RE: tomcat and active directory
In order to query the LDAP tree, you have to bind to it. Binding requires
that anonymous bind be enabled, or that you bind with a user id and
password. This is just how LDAP works.
The information that I sent you was information I learned while creating an
LDAP authentication module for our software.

Re: Knowing the line when the error happen
Fermin,
This information is usually recorded in your log files, or alternately
printed into the console window if Tomcat is running in windowed mode
(because you manually launched the tomcat5 executable).
Look in {Tomcat Home}/logs/ for a file like stdout_20050802.log
(stdout_MMDD.log). There are other places this file might live,
but that's the default.

Log.say(INTERNALE: [+d+] Dumping HTTP header START);
Enumeration e = req.getHeaderNames( );

String value = req.getHeader(name);

}

}
Should get the Referer
But it gets a null
Why would it get a null ? Every page has a referrer.

Re: Knowing the line when the error happen
Ah. Looks like I answered the wrong question. It's a two step process
to make a servlet from a .jsp file: first is translate it (make a .jsp
into a .java), the next is compile it.
When the jsp is made into a servlet it gets all of the stuff added to
it that makes it into a real java file (public final class jsp name
extends org.apache.jasper.runtime.HttpJspBase implements
org.apache.jasper.runtime.JspSourceDependent etc etc). The newly
created file is placed into a the work directory: by default, that's
something like:
{Tomcat Home}/work/Catalina/hostname/context/org/apache/jsp/,
which is the file that's referenced in the error above. You'll have to
look at the line number in *that* file (line 55 in the java file) and
see what code is at that line, then look and see where that code is in
the JSP.
For example, in the JSP you might see:
%= foo.toString() %
when in the java file it looks like:
out.print( foo.toString() );
It's really the same code, but it just looks different; read the java,
and refer back to the JSP and it will probably make sense. One thing
that can screw you up and be hard to track down is misplaced parens ()
or braces {} becuase the compiler matches up the braces in your jsp
code with the java code added at translation time and reports
seemingly nonsensical errors.
Hope this all helps.

Fermin,
This information is usually recorded in your log files, or alternately
printed into the console window if Tomcat is running in windowed mode
(because you manually launched the tomcat5 executable).
Look in {Tomcat Home}/logs/ for a file like stdout_20050802.log
(stdout_MMDD.log). There are other places this file might live,
but that's the default.

Re: Shall jdom be handled differently?
That import statement looks ok but the error is being reported for line 21 in SyndFeedInput. Looking at the code (link below) it's a common or garden import statement. https://rome.dev.java.net/source/browse/rome/src/java/com/sun/syndication/io/SyndFeedInput.java?rev=1.5view=autocontent-type=text/vnd.viewcvs-markup Not sure what is wrong so I would: 1) Check that the jdom jar is readable, non-corrupt and contains org.jdom.Document 2) Delete the work directory and restart tomcat. 3) Move the jsp out from under WEB-INF (tomcat shouldn't be directly serving pages from under there anyway) to see if that's the problem. 4) Tear hair out. etc, etc Jon Vernon wrote: Hi, Jon, Thank for your quick response.

Objet : Re: Knowing the line when the error happen
Ah. Looks like I answered the wrong question. It's a two step process
to make a servlet from a .jsp file: first is translate it (make a .jsp
into a .java), the next is compile it.
When the jsp is made into a servlet it gets all of the stuff added to
it that makes it into a real java file (public final class jsp name
extends org.apache.jasper.runtime.HttpJspBase implements
org.apache.jasper.runtime.JspSourceDependent etc etc). The newly
created file is placed into a the work directory: by default, that's
something like:
{Tomcat Home}/work/Catalina/hostname/context/org/apache/jsp/,
which is the file that's referenced in the error above. You'll have to
look at the line number in *that* file (line 55 in the java file) and
see what code is at that line, then look and see where that code is in
the JSP.
For example, in the JSP you might see:

Re: Java 1.4.2_08 and up breaks Jstl
Hi Do you have a link to a Sun Bugparade entry describing the problem? No I don't. I have performed a test of my own. I have installed j2sdk 1.4.2_05 and j2sdk 1.4.2_08 and j2sdk 1.4.2_09. I have installed these to the /opt directory. I have my JAVA_HOME pointed to /opt/java. First I point /opt/java to /opt/j2sdk1.4.2_09 and restart tomcat. The bug happens again. I then point /opt/java to /opt/j2sdk1.4.2_08. I restart tomcat and the same bug occures. I then point /opt/j2sdk1.4.2_05 to /opt/java, restart tomcat and BINGO no bug. Apparently versions java 2 sdk 1.4.2_09 and java 2 sdk 1.4.2_08 cause the bug to occure just as in the forum thread. I have tried a different tomcat version but no luck. Any ideas anybody? Maybe a configuration change that has occured in the new java versions? Martyn Hi, I'm not convinced by that forum thread.

Context reloading
I'm having a problem reloading / redeploying one of my web applications using
the ant tasks.
The target I am trying to run is this and it fails on when stopping the
application.
target name=redeploy description=Reinstall the existing web application
stop url=${url} username=${username}
password=${password} path=${path}/
delete dir=${base}/
copy todir=${base}
fileset dir=${content.base}/
/copy
start url=${url} username=${username}
password=${password} path=${path}/
/target
The error message given is removeAttribute: Session already invalidated
which seems to be exactly the same as this bug
http://issues.apache.org/bugzilla/show_bug.cgi?id=30489
Unfortunately I don't have a test case either but I am running tomcat 5.5.9.
Three other web applications deployed in the same instance of tomcat can be
redeployed with an essentially identical ant target just fine. It is just
this one application that fails. Annoyingly when it fails it takes out the
tomcat manager as well meaning the whole of tomcat needs to be restarted. Any
ideas what might be wrong?
TIA

Re: data push
From: Paul Wallace [EMAIL PROTECTED] Sent: Wednesday, August 10, 2005 6:38 PM Hi and thanks for that, That's the crux of my question! The data (I am unsure of the protocol it is delivered in) is sent at random points in time i.e not from any request. I wish to create particularly the client (server B) that listens for this data. I (mistakenly) mentioned server A to mimic the data pushes. I can write something to fire off data at intermittent times, but I am more interested in how to capture that data, when no request has been made. This is the reason why I first questioned on Sockets. Perhaps I should have been clearer from the off! Yea, that protocol detail is kind of important. As others have said, Tomcat is set up for HTTP requests, and pretty much ONLY HTTP requests. As much as it would be nice to extend GenericServlet to work with ANY protocol, in truth it just doesn't happen and is not really practical. The GenericServlet interface is still pretty heavily tainted by HTTP. If you want to listen to HTTP datastreams, then Tomcat is the hot tip. If not, then you can start with the Jakarta Avalon project (which is basically dead). Avalon was a lower level container designed to be the boiler plate so you can focus on implementing your own protocols. While the actual Avalon project is dead, the current project page shows you how it has forked into several other projects, so you can use that as a starting point to perhaps hunt down a framework to more easily handle your own protocol. Now, to be fair, if you don't have any real VOLUME of data (lots of connections, high load, vs just the occasional chit-chat), you may well be able to write a simple server in just plain Java. A simple server is not difficult, and there are no doubt several examples on the net. Listening to a socket is no longer the rocket science it once was. Just depends on your tolerance for getting it to work vs learning a framework. Finally, if you REALLY want to dig in to the Tomcat internals, you can break it into little pieces and bits and hammer to fit to support your protocol. Also, there's the book How Tomcat Works which is actually a pretty good book if you want to know how to write a network server in Java.

Problems with sendredirect
Hi. I just has beginning to use the Tomcat, for programming in JSP. I have the 5.0 version. I make a web app that uses, in some jsp's files, the command response.sendRedirect. When i execute the pages locally in my computer, works fine, but, i if try to test the pages from another computer, i get an error. This is the way i was executed the sendRedirect for test in another machine, and always get an error: response.sendRedirect(http://localhost:8080/activation/obligatorios.jsp;) response.sendRedirect(http://192.168.1.137:8080/activation/obligatorios.jsp ) response.sendRedirect(http://mycomputer:8080/activation/obligatorios.jsp;) response.sendRedirect(/obligatorios.jsp) response.sendRedirect(activation/obligatorios.jsp) I think that could be some context problems because, for make the webapp structure, i copied one example webapp that comes with the tomcat, then i deleted and renamed those files and directories that i dont use (off course, the web-inf still exist) What can i do ? Is there is some file where i must configure the context of the webapp ? Thanks !! - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Tomcat authentication with Kerberos
I have a standalone Tomcat 5.0 instance, and a third-party webapp that has support for authentication via LDAP. Of course, we don't have LDAP, we have Kerberos. It should be a simple matter to plug in a different Realm, right? I'm finding it hard to believe that no one has done this (Tomcat authentication with Kerberos) yet, but Google just isn't turning up anything. I started at the Realm HowTo [0] and found the JAASRealm section. From here it looks like I need to write my own LoginModule. Except... there is com.sun.security.auth.module.Krb5LoginModule [1]. Can I just use that? (I thought we weren't supposed to use com.sun.* classes, but it's not as though I can write my *own* Kerberos LoginModule!) After I (somehow) get the user authenticated with Kerberos, then I need to look in a [non-JDBC] database to get the Role information. For User and Role, it looks like I can extend AbstractUser and AbstractRole... but where does the code go that would create instances? In short, I'm confused. Can anyone offer advice on what I need to do to make this work? Or better yet, point to someone who has already done it? Thanks in advance!

Re: data push
Darryl, Your remark about POJOs being part of the API prompted me to chime in -- William pretty much gave you the general answer, that Tomcat doesn't seem to be the best way to go for this (because everything is passed via http). I would point out that just as you can serialize/stream objects to disk and read them back again, you can do the same over network sockets -- in fact the code is nearly identical. So you can load up an object with all sorts of instance data on this end, open a socket connection to some other listening server (not tomcat, just a raw listener -- but that's only maybe 100 lines of code) and write(...) the object to the stream, then read it out on the other end. The serializing/deserializing concept of java will automagically reconstitute the object on the receiving end. (Assuming they both have access to the class at runtime). I seem to recall there being a very nice tutorial for java sockets on the sun java website; you could probably work up the basic communication in under an hour.

Also, there's the book How Tomcat Works which is actually a pretty good book if you want to know how to write a network server in Java.

Tomcat and workers(2).properties files
Greetings, Does Tomcat itself ever use either the workers.properties or the worker2.properties files? My understanding is that these files are just example property files for the Apache2 mod_jk(2) modules and that Tomcat itself never references these files? Is this true?

HTTP Status 500
I have having problems with a servlet using Tomcat 5.0.25. In my research it appears to be associated with the Invoker. However, when I go through the Environmental and Container Dependencies everything checks out. I have my system set up to run both a Tomcat project and a JBoss project simultaneously. Up until now, I have had no problems with that configuration. The following is the display seen in the browser: * HTTP Status 500 - _ type Exception report message description The server encountered an internal error () that prevented it from fulfilling this request. exception javax.servlet.ServletException: Error instantiating servlet class com.ikano.wildblue.web.QueueServlet org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:117 ) org.apache.coyote.tomcat5.CoyoteAdapter.service(CoyoteAdapter.java:160) org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:793) org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.processConne ction(Http11Protocol.java:702) org.apache.tomcat.util.net.TcpWorkerThread.runIt(PoolTcpEndpoint.java:571) org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.jav a:644) java.lang.Thread.run(Thread.java:534) root cause java.lang.NoClassDefFoundError: com/ikano/wildblue/Queue java.lang.Class.getDeclaredConstructors0(Native Method) java.lang.Class.privateGetDeclaredConstructors(Class.java:1610) java.lang.Class.getConstructor0(Class.java:1922) java.lang.Class.newInstance0(Class.java:278) java.lang.Class.newInstance(Class.java:261) org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:117 ) org.apache.coyote.tomcat5.CoyoteAdapter.service(CoyoteAdapter.java:160) org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:793) org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.processConne ction(Http11Protocol.java:702) org.apache.tomcat.util.net.TcpWorkerThread.runIt(PoolTcpEndpoint.java:571) org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.jav a:644) java.lang.Thread.run(Thread.java:534) note The full stack trace of the root cause is available in the Apache Tomcat/5.0.25 logs. _ Apache Tomcat/5.0.25 * Here is the information from the Log file... # 2005-08-11 16:34:48 StandardContext[/jsp-examples]SessionListener: contextDestroyed() 2005-08-11 16:34:48 StandardContext[/jsp-examples]ContextListener: contextDestroyed() 2005-08-11 16:34:49 StandardContext[/servlets-examples]SessionListener: contextDestroyed() 2005-08-11 16:34:49 StandardContext[/servlets-examples]ContextListener: contextDestroyed() 2005-08-11 16:35:02 StandardContext[/balancer]org.apache.webapp.balancer.BalancerFilter: init(): ruleChain: [org.apache.webapp.balancer.RuleChain: [org.apache.webapp.balancer.rules.URLStringMatchRule: Target string: News / Redirect URL: http://www.cnn.com], [org.apache.webapp.balancer.rules.RequestParameterRule: Target param name: paramName / Target param value: paramValue / Redirect URL: http://www.yahoo.com], [org.apache.webapp.balancer.rules.AcceptEverythingRule: Redirect URL: http://jakarta.apache.org]] 2005-08-11 16:35:02 StandardContext[/jsp-examples]ContextListener: contextInitialized() 2005-08-11 16:35:02 StandardContext[/jsp-examples]SessionListener: contextInitialized() 2005-08-11 16:35:05 StandardContext[/servlets-examples]ContextListener: contextInitialized() 2005-08-11 16:35:05 StandardContext[/servlets-examples]SessionListener: contextInitialized() 2005-08-11 16:36:27 StandardContext[/jsp-examples]SessionListener: contextDestroyed() 2005-08-11 16:36:27 StandardContext[/jsp-examples]ContextListener: contextDestroyed() 2005-08-11 16:36:28 StandardContext[/servlets-examples]SessionListener: contextDestroyed() 2005-08-11 16:36:28 StandardContext[/servlets-examples]ContextListener: contextDestroyed() 2005-08-11 16:36:47 StandardContext[/balancer]org.apache.webapp.balancer.BalancerFilter: init(): ruleChain: [org.apache.webapp.balancer.RuleChain: [org.apache.webapp.balancer.rules.URLStringMatchRule: Target string: News / Redirect URL: http://www.cnn.com], [org.apache.webapp.balancer.rules.RequestParameterRule: Target param name: paramName / Target param value: paramValue / Redirect URL: http://www.yahoo.com], [org.apache.webapp.balancer.rules.AcceptEverythingRule: Redirect URL: http://jakarta.apache.org]] 2005-08-11 16:36:47 StandardContext[/jsp-examples]ContextListener: contextInitialized() 2005-08-11 16:36:47 StandardContext[/jsp-examples]SessionListener:

Tomcat 5.5 upgrade + logging problems
Hi. I have searched through archives and online for such solutions for the depreciated Logger element. We have a virtual host setup and requires separate logs for each host. We have followed the instructions such as this: jakarta.apache.org/tomcat/tomcat-5.5-doc/logging.html we've put log4j.properties file in each host's WEB-INF/classes folder, and log4j1.2.8.jar into WEB-INF/lib in each host still, nothing seems to work. there must be something we are missing.
