Tomcat 5 - Datasource Connection Pooling
Finally after long struggle I could get the datasource things running. The things are working when i specified all into GlobalResources and GlobalContext inside server.xml My server.xml is something like below.. - GlobalNamingResources Resource auth=Container name=mspool type=javax.sql.DataSource/ ResourceParams name=mspool parameter nameurl/name valuejdbc:microsoft:sqlserver://localhost:1433;DatabaseName=sbcs/value /parameter parameter namemaxIdle/name value30/value /parameter parameter namemaxActive/name value100/value /parameter parameter namedriverClassName/name valuecom.microsoft.jdbc.sqlserver.SQLServerDriver/value /parameter parameter namemaxWait/name value1/value /parameter parameter nameusername/name valuemanisha/value /parameter parameter namefactory/name valueorg.apache.commons.dbcp.BasicDataSourceFactory/value /parameter parameter nameselectMethod/name valuecursor/value /parameter parameter namepassword/name valuemanisha/value /parameter parameter nameremoveAbandoned/name valuetrue/value /parameter parameter nameremoveAbandonedTimeout/name value60/value /parameter parameter namelogAbandoned/name valuetrue/value /parameter /ResourceParams /GlobalNamingResources ...

But i do not want it inside global naming resources / default context - but i want it only specific to my web application. i also understand that Context - should not be used for TomCat5.0 - but need to put inside /META-INF/context.xml. 1)My problem is my working directory is different. I use ant to create war file and then i manually stop the server - delete existing war file / existing directory (This is due to some Win TomCat problem .??..). Then i deploy it using TomCat Manager. It automatically creates META-INF file for me, i do not have META-INF inside my working directory. So where i can put my context.xml ? 2) What shall i put inside context.xml and what shall i put inside server.xml / web/xml ? I tried many different ways but when i use context and as there is no such application (because i delete and re-deploy it) - tomcat server does not run my application.

connection Pool leaking - how to detect it ?
I just shifted to DataSource Connection pooling. I followed http://jakarta.apache.org/tomcat/tomcat-5.0-doc/jndi-datasource-examples-howto.html Here they have given 3 parameters to specify to control leaking such as removeAbandoned, removeAbandonedTimeout, logAbandoned 1) Is there any way to detect in which program / connection, resultsets etc are not closed. I tried my best not to keep it open, but in case by mistake it happend to be then how i can detect it ? 2) Also what is the meaning of logAbandoned - where i can see the log of this ? regards Manisha __ Do You Yahoo!?

sharing webapplication
Hi to everybody, I need an idea. suppose I have some webapp that i need to share among some other webapplication. For example, suppose I have three customer website each that need the access to a reserved area. Suppose thet I want to use just on login webapp shared among all my customers; suppose I need that every login page need to by skinned as the rest of the website. The main issue I want to obtain is to manage just one shared webapp fot all customers to better menaging upgrades, bug fixing and so on. I think that skin the website is not a problem... I shoud use XML + XSL(T) to skin... the matter is how to share. What are the best way to do this?

Re: Tomcat 5 - Datasource Connection Pooling
Hi! 1)My problem is my working directory is different. I use ant to create war file and then i manually stop the server - delete existing war file / existing directory (This is due to some Win TomCat problem .??..). Then i deploy it using TomCat Manager. It automatically creates META-INF file for me, i do not have META-INF inside my working directory. So where i can put my context.xml ? You have already answered this yourself, META-INF/ directory of your war file. The only way to avoid the META-INF directory is to not use a war file, as a war file simply is a jar file, and the META-INF is part of the jar file specification. 2) What shall i put inside context.xml and what shall i put inside server.xml / web/xml ? The example pages: http://jakarta.apache.org/tomcat/tomcat-5.0-doc/jndi-datasource-examples-howto.html tells you exactly what to put in each file. You just have to read them one more time and keep focused. I'll give you some hints as well: - Leave server.xml the way it was before you started tampering with it. - Copy CATALINA_HOME/conf/enginename/servername/yourapp.xml, to your context.xml file, and add your resource specification inside the context as in the examples. Then include context.xml in your war file in the META-INF dir. Your app must be running for the yourapp.xml file to exist as it is deleted when you undeploy your app. - In web.xml you need to add a resource-ref as you can see from the examples Good luck Trond - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: What is it mean that Java code does not belong in well designed JSP pages?
I just read this thread and didn't quite understand it. If it means what it seems to mean on the surface, I'm doing everything wrong. I belong to the camp that thinks Java code in JSPs is evil. I happen to think that tag libraries are wonderful. JSPs are HTML documents that are empowered to retrieve information from Java objects. At least that's how I think of them. The focus in a JSP is HTML/CSS presentation and design - all the data should be retrieved, validated and prepared for presentation before you call the JSP. If you work on a large, complex project, you must approach it that way. If you're working on something simple, quick and dirty, then by all means do all your coding in JSPs - that's what makes them cool. Debugging code in JSPs is very painful. Debugging tag libraries is the same as debugging any ordinary Java object. HTH Harry Mantheakis - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
controlling and limiting threads launched by servelts
Hi situation: A tomcat instance where several independent webapps are hosted. (kind of shared hosting). scenario: A developer for one of this webapp is kind of lazy (or not that skilful) and launches a new thread during init(). but he does not terminates this thread during the destroy() of the servlet. effect: so when he reloads his webapp the thread keeps on running. further more his webapp could in developing state where this reload happen very often. so after some time I've a lot of orphaned threads running in my tomcat VM. When I notice this, or a Developer complains that something must be wrong on my system as his thread behaves weired (most often non-deterministic behaviour because of race conditions when more than one of these threads are running) I send information about correct launching and terminating threads from a servlet of course. But this solution leaves a unpleasant feeling. further more I'll have to restart tomcat to get rid of these threads. I would prefer a technical solution which prevents this. I know that I can't isolate webapps 100% against each other concerning system ressources (slugish servlet can allocate too much memory and cause an OutOfMemoryError etc.). I did had a look a java policy but you can't either prevent a thread from being started, nor have any fine grained control on threads. non the less here are my questions: is it possible to... - prevent a serlvet from launching threads at all? - limit the number of threads a webapp/servlet can launch simultaneously? - automatically terminates all threads a webapp/servlet has launched when stopping context? (kind of GC for threads) notice: all this should be possible without cooperative behavoiur of the serlvet developer and so implememented completely transparent to them. is this possible at all? any ideashow to implement? thanks in advance cu romeo -- Romeo Benzoni [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
precompilation and JSTL
Hello all!
I am trying to precompile my JSPs using org.apache.jasper.JspC.
Problem: The ones that use JSTL result in uncompilable Java code.
[Sorry for my english. Is it uncompilable or incompilable?]
Example:
%@ taglib uri=http://java.sun.com/jstl/core; prefix=c %
titleJSTL test/title
c:if test=${true}
c:out value=this is JSTL :) /
/c:if
The resulting Java file contains this line:
if (_jspx_meth_c_out_0(_jspx_th_c_if_0, _jspx_page_context))
return true;
The (Eclipse) compiler complains:
The method _jspx_meth_c_out_0(JspTag, PageContext) in the type
test_jsp is not applicable for the arguments (IfTag, PageContext)
IfTag is org.apache.taglibs.standard.tag.el.core.IfTag.
JspTag is javax.servlet.jsp.tagext.JspTag.
IfTag extends javax.servlet.jsp.jstl.core.ConditionalTagSupport.
ConditionalTagSupport extends javax.servlet.jsp.tagext.TagSupport.
TagSupport implements javax.servlet.jsp.tagext.JspTag.
So this looks right. Any idea what the problem is?
I am using JSTL 1.1.2 with Tomcat 5.0.26.
best wishes,
Marcus Beyer

open Excel 2000 bug
Hi All, I have a JSP page that eventually opens Excel page. I got my content type set to be application/vnd.ms-excel I also work with FOP to serialize the Excel. I got this working for both Win 2000 and XP , and for Office XP and 2003, but for Office 2000 I got an Error generating the Ecxel. If i look at localhost access log, I see that the page is somehow been called 2 again times: GET /ExcelReportGenerationPage.jsp?reportName=ResourceExcelRep HTTP/1.1 200 5120 LOCK /ExcelReportGenerationPage.jsp?reportName%3DResourceExcelRep HTTP/1.1 500 2170 GET /eBopBrowser/jsp/ReportGenerationPage.jsp?reportName=ResourceExcelRep HTTP/1.1 200 5120 I know that 500 indicates an internal Error of the server, but i don't understand what is the lock doing here. I understand that it relates ot webDav - but why is it here? od i use WebDav without my knowledge? I use tomcat 5.027 How come in Excel 2000 i got this Error?

I am having problems with controlling the redirection of a website. http://www.acf.hhs.gov/programs/core/hsrc/ However, I was asked to change this the headstart website to redirect to this site instead, http://www.acf.hhs.gov/programs/opre/hsrc/ Well, I went into IIS and looked up the site's configuration, clicked on the Home Directory tab and set the radial option from Directory on this system to URL redirection because I thought this was the correct way. http://www.acf.hhs.gov/programs/opre/hsrc/ that link BACK to the headstartresearchconf.net... but as you would expect since I chose the radial option URL redirection the site simply loops back. http://www.acf.hhs.gov/programs/opre/hsrc/ http://www.acf.hhs.gov/programs/core/hsrc/. http://www.acf.hhs.gov/programs/core/hsrc/ http://www.acf.hhs.gov/programs/opre/hsrc/, but then the links on that site can't make it to the headstartresearchconf.net references they are trying to reach... because I removed the ISAPI filter named tomcat. I really need to fix this mess, because it is a heavily used site. http://www.acf.hhs.gov/programs/core/hsrc/ with the ISAPI filter in place, but I don't know what is generating the URL redirection. Could it be a jsp, I honestly don't know because I am not a java developer. If anyone could help me or guide me through this process it would be greatly appreciated.

Re: What is it mean that Java code does not belong in well designed JSP pages?
Debugging code in JSPs is very painful. Debugging tag libraries is the same as debugging any ordinary Java object. I pretty much agree with everything Harry says and I do so in spades as they say. You can, as a tip, make debugging JSP easier by putting the whole page in a try/catch exception trap.

Hi, I'd like to know how setting a custom TrustManager in Tomcat 4.1.31. I have my custom provider installed and working ok. I tried to override ssl.TrustManagerFactory.algorithm property with my custom TrustManagerAlgorithm but tomcat seems to ignore it ... The only thing i achieve is to set a custom TrustStore with javax.net properties ... But i want a dynamic (CRLs, OCSP, etc.) TrustStore, not a static one ... I can't find any information about TrustManagers in documentation. Any help would be greatly appreciated. BQ.

But still my pages do not work if I specify to use the jstl 1.1 taglib.

You can have the various application URLs point to the same webserver app, as Parsons pointed out. However, why don't you want them to share, except the skin, everything on the website?

out of memory error with more than a few sites
Hi, I am getting an out of memory error when I start Tomcat. I read posts on this in the past and followed some instructions to increase by min and max memory settings in catalina.sh. I have 1028 MB on this server and so I increased the min to 128 and the max to 768. The server was working fine when I had a few test sites on it. I am currently using Apache httpd 2.0.52, Tomcat 5.0.28 and mod_jk2 configured with workers2.properties and so that tomcat can listen to apache requests. Apache httpd serves static files and Tomcat is set to work on jsp's with the directive: LocationMatch /*.jspJkUriSet worker ajp13:localhost:8009/LocationMatch The problem showed up when I started migrating some sites over and increased the number of hosts significantly. I created 80 VirtualHosts in httpd.conf and 80 hosts in server.xml. Then I created 80 corresponding directories in webapp, each with META-INF and WEB-INF subdirectories. Even though all these directories and subdirectories are empty, when I start up Tomcat, it tries to deploy them all and throws the out of memory error. If I remove most of the hosts in server.xml, everything runs fine again. My goal is to have these sites each with a large number of static pages and only a few jps's which are Lucene's search.jsp and results.jsp. After this I want to have these sites each has a portal component using Jetspeed 2. I know that if Tomcat was not in the picture this server would be able to handle many more sites, but is 80 hosts with only a few jsps in each too much for Tomcat on an average modern Web server? How can I optimize this? Below I have included code snippets of my httpd.conf and server.xml and workers2.properties.

Start Tomcat 5.5.4 in the Background with No Console (Windows)
Hi all, I'm wondering -- is there a way to start Tomcat 5.5.4 in the background on Windows, without seeing the console, and without running it as a service? Here's my situation: I have a webapp running that sometimes needs to access network folders that are only mapped when the user logs in to windows. If I use a service to launch Tomcat, it starts using the SYSTEM account, which doesn't have access to the network drives. Now, I know I can change the Log On As to user a local account, but that also means I have to change the local account's security privileges (to allow that account to run services), etc., which is not a viable solution for me. Instead, I was thinking that I could just start Tomcat in the background when the user logs in (by putting something in the Startup folder or something like that). That way, Tomcat would be launched by the user, and then it would be able to access network drives. But, I don't know if there is a way to start Tomcat without the console visible (so that Tomcat's execution is still transparent to the user, as it would be if it were run as a service). I guess I would also have to figure out a way to have the shutdown script called when the user logs out. That could be a pain as well, couldn't it? Does anyone have any thoughts on this? Thanks, Matt Mejaski

I have Tomcat 4.1.27 on a Linux box at a particular public IP address, and I want to make it forward ALL requests to a Tomcat on a Windows box at another public IP address. Over the weekend, we changed the DNS to the Linux box, but now we need to roll back to the Windows box, and we already changed the DNS through our ISP, and a lot of folks are hitting the Windows box, but some people are still hitting the Linux one. So, we want to turn on the Tomcat on the Linux box and somehow send all those folks to the Windows one. Is there any way to do this? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re-Post SSL and Tomcat
I would really appreciate any help on this. I have two applications running on a Tomcat server. One is the main webpage and the other is a shopping cart for that webpage. I would like to set up a secure checkout for the cart. Is it best to encrypt the whole cart or just part of the cart? Should the main website and the cart be on the same server? What eles should I look out for? Thanks - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Sending email with zip file attach problem

Re: precompilation and JSTL
Just a thought:
Last I knew using the j2ee jar w/ Tomcat == EVIL. You can either use
the j2ee distribution on Sun's site OR Jakarta Tomcat (w/ j2sdk, not
j2ee), but never j2ee and jakarta tomcat together. It'll create some
really ugly version conflicts. If you use jakarta tomcat from
jakarta.apache.org, use the jar files that have the specific functions
you need instead.
For jstl, that would be the standard-1.1 tag lib available here:
http://jakarta.apache.org/taglibs/index.html. D/L the standard taglibs,
drop the jars in your WEB-INF/lib directory, and include the taglibs in
your web.xml per the docs. Restart the context and your done.

Are you sure you want

and not
%@ taglib uri=http://java.sun.com/jsp/jstl/core; prefix=c %
But still my pages do not work if I specify to use the jstl 1.1 taglib.
Example: c:out value=1 + 2 = ${1 + 2} /
With 1.0 taglib I get 1 + 2 = 3.
With 1.1 taglib I get 1 + 2 = ${1 + 2}.
Any idea about this?

Re: Sending email with zip file attach problem
It is an example of sending bulk mails with
attachment.
You have to write the uploaded file into a temporary
directory.
See the attachments. I hope the example could be
useful.

Re: precompilation and JSTL
Tim Funk schrieb:

Yes it is.
The problem has to do with precompilation, because it works if I deploy
the JSPs instead of the servlets.
Example: c:out value=1 + 2 = ${1 + 2} /
The precompiled Java code looks like this:
_jspx_th_c_out_1.setValue(new String(1 + 2 = ${1 + 2}));
Whereas the Java code compiled after deployment looks like this:
_jspx_th_c_out_1.setValue((java.lang.Object)
org.apache.jasper.runtime.PageContextImpl.proprietaryEvaluate(1 + 2 =
${1 + 2}, java.lang.Object.class, (PageContext)_jspx_page_context,
null, false));
Why is it different??

bizarre authentication problem
I have an Tomcat server on an internal network configured to require basic authentication. This works fine when I use IE or Java code to access a site, but when I try to access the site using Firefox, the user/password is never accepted. I have packet sniffed the GET calls from both IE and Firefox and the Authorization header is the same for both. I can access the Tomcat Manager using basic auth and external sites with auth so it's not entirely broken. Tomcat has maxKeepAliveRequests set to 1 (to deal with a .NET SOAP interop problem) - that's the only oddball config in Tomcat. I realize this is more likely a Firefox problem than a Tomcat one, but I'm wondering if anyone has seen behavior like this.

AW: Meaning of threads
Hi the number of threads will depend on the size of your machine, but to support many concurrent users, you will want to turn off keep alive connections, as these will have the opposite effect. Wouldn't it make more sense to enable keep alive connections and increase the thread count - if memory suffices? Even if not, the keep-alive timeout should be decreased instead of disabled all together. Additionally I'd like to see tomcat to be able to drop keep-alive connection exactly then, when all threads are busy and a new connection is to be etablished. That would give us the benefit of keep alive connections - faster data delivery for users - as well as optimal thread usage even on small thread pools. What is your opinion? Regards, Steffen smime.p7s Description: S/MIME cryptographic signature
Re: Meaning of threads
I would also consider turning of keepalive. Unfortunately tomcat (and apache) both setup one thread per connection.

Re: Meaning of threads
no, think about it a little bit longer, what does a keepalive connection do, it hogs one thread per client, not per concurrent user. so now other clients will be stuck waiting cause you have keepalive turned on, and a user is sitting idle doing nothing, but yet, taking up server resources Filip - Original Message - From: Dola Woolfe [EMAIL PROTECTED] To: Tomcat Users List tomcat-user@jakarta.apache.org Sent: Monday, January 24, 2005 3:50 PM Subject: Re: Meaning of threads That's counterintuitive, isn't it?

Wouldn't it make more sense to enable keep alive connections and increase the thread count - if memory suffices? Unfortunately not. IMHO threads are over used and over rated. Have a look at the reasons THTTPD and Zeus webserver were created. I was told that the 'Java Servlet Spec' (I think this was the one) requires one thread per connection. I can understand the reasoning behind this, as it makes the implementation much easier. In my experience however, this does NOT work well in a high traffic situation. It makes NO sense for a machine to need to deal with 1000+ threads. (Unless of course you have an E15000 in the basement with 1000 processors). I had major problems with Debian Woody as the supplied Glib C as I was unable to get java to start more than 250 threads. Sarge was better in that it supported the new linux threading library out of the box. I do not have any experience with Solaris or Windows when dealing with that many threads. You need to disable keep-alives, becuase if you don't you end up wasting a lot of threads that just sit waiting for the next request on that connection - meaning even more threads just hanging around. The scary thing is, imagine something hangs on the backend for 30 seconds, and then all your 1000 threads start trying to do something at once You will end up with a load of 1000 and ALL your requests will take a long time to return. It may be interesting to replace the http connector for tomcat with one that uses select and uses 'threads' as a type of worker pool. This way, you can deal with all the connections in the select loop (incl. keep-alive) and still have the advantage of not needing to remember state due to the worker threads to the back end...

Re: Tomcat Error: java.lang.NoClassDefFoundError:
Hi QM, Thanks for your response. In between Tomcat working and breaking, I had installed Cactus. I think that actually changed something, somewhere on the classpath which wasn't actually in tomcat's directory structure. When I reinstalled tomcat, I did completely remove it, then reinstall. I've managed to fix the problem now, by removing my Java SDK and reinstalling that. Not the world's greatest solution, but it worked. And, yes, that was the full stack trace from catalina.out.

Re: AW: Meaning of threads
In my experience however, this does NOT work well in a high traffic situation. I'm sure you're not saying that Tomcat does NOT work well in a high traffic situation. You are just saying that in a high traffic situation one should turn off keep alives. Am I guessing correctly that I have only a few persistent visitors (such as an office web application that is a front end to a database) then turning keep alives on will cause the data to be returned to the user more promptly. But if, say, you are running an eBay type site, keep alives should be turned off. Any single user will suffer a little but the traffic will be handled better. Aaron Fude __ Do you Yahoo!?

Hi, Since this doesn't appear to threads issue I'm taking it out into a separate thread. I'm running TC 5.4.4 on port 80 with no Apache on XP Pro.

When he then uses the browser to go to one of the pages served by the server he gets a page cannot be displayed. After about 2 min (we never really timed) things return to normal. Any suggestions?

Re: Does JDBCRealm close connections?
In a quick scan of the source (4.1.30). The realm does not use pools. It opens the connection upon authentication. Then closes it right after. All in the same method. There is a note about adding pooling, and this may be one reason why. If you have a limit on the number of connection your dbengine can support then this may be the cause. So for the last question, yes, it would keep opening the needed connections for logins. But it closes them promptly after retrieval of the data.

Re: Tomcat Bug?
As far as I know. Under IE options for the settings in the files section you can set that to check for a new page on each visit. Pressing F5 is suppose to do a new request. Also I remember some mention about file dates. Make sure date on new file is later than on original file. There have been several threads on this but each had a slightly different twist. Check the archives. If you delete the app does the page still respond or give you an error?

Deploying a Servlet to Tomcat 5.0
Hi,
I have been trying to deploy a simple servlet to
Tomcat 5.0. Tomcat is installed on WIndows XP.
This is what I did:
1. Created a directory structure under
$TOMCAT_HOME\webapps as follows:
ROOT\WEB-INF\classes
2. Moved the class(HelloServlet.class) to the
above created directory.
3. Bounced Tomcat.
4. Attempting to access the class as
http://localhost:8080/servlet/HelloServlet gives
me the error:
HTTP Status 404 - /servlet/HelloServlet
type Status report
message /servlet/HelloServlet
description The requested resource
(/servlet/HelloServlet) is not available.
Please advise on how I should be deploying this simple
servlet.
The servlet is code is given below:
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
/** Simple servlet used to test server.
* P
* Taken from Core Servlets and JavaServer Pages 2nd
Edition
* from Prentice Hall and Sun Microsystems Press,
* http://www.coreservlets.com/.
* copy; 2003 Marty Hall; may be freely used or

*/
public class HelloServlet extends HttpServlet {
public void doGet(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
response.setContentType(text/html);
PrintWriter out = response.getWriter();
String docType =
!DOCTYPE HTML PUBLIC \-//W3C//DTD HTML 4.0
+
Transitional//EN\\n;
out.println(docType +
HTML\n +
HEADTITLEHello/TITLE/HEAD\n
+
BODY BGCOLOR=\#FDF5E6\\n +
H1Hello/H1\n +
/BODY/HTML);
}
}
