I recommend using the Tomcat classloader instead (configured in the jboss-service.xml). This is a lot more "webapp friendly" than the JBoss classloader. I will properly implement the getURLs of the fake ENCLoader (your proposed patch is bad). http://www.jboss.org/index.html?module=bb&op=viewtopic&p=3825031#3825031";>View the original post http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=3825031>Reply to the post --- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.

[JBoss-user] [HTTPD, Servlets & JSP] - Re: Standard taglib with jboss 3.2.3, tomcat 5
After some analysis, we were able to locate the problem in the WebCtxLoader.java
(present in the tomcat/src/main/org/jboss/web/tomcat/tc5 directory) implementation.
The problem is in the setWarURL method. Here instead of adding the URLs to the
ENCLoader (ctxLoader), it has been added to the parent (UnifiedClassLoader) loader.
When I changed the implementation to add the URLs to the ENCLoader, things are working
fine now. I.e., the Tomcat is able to load the tlds present in the jar files now
properly. This is because, the TldLocator needs the getURLs() to return properly for
locating the .tld files. The UnifiedClassLoader by design ignores the getURLs() method
and returns a empty-array. So, changing the URL addition to the ENCLoader helps return
proper URL [] and thus the location of resources too!
I've given below the code-snippet of the change made:
public void setWarURL(URL warURL) throws MalformedURLException
{
//Add the URLs to the ctxLoader instead of the delegate!
//delegate.addURL(classesDir.toURL());
ctxLoader.addURL(classesDir.toURL());
//Add the URLs to the ctxLoader instead of the delegate!
//delegate.addURL(jars[j].toURL());
ctxLoader.addURL(jars[j].toURL());
}
Hope this is useful.

Suresh.K.V.

[JBoss-user] [HTTPD, Servlets & JSP] - Re: Standard taglib with jboss 3.2.3, tomcat 5
I ran into the same problem trying to deploy the JavaServer Faces 1.0 Beta samples on JBoss 3.2.3, with Tomcat 5. The suggested work-around (i.e. false) appears to solve the problem of locating the taglibs, but I found that it led to other classloader-related problems. For example, the first thing I ran into was that debug classes contained within jars in the sample war's WEB-INF/lib directory didn't match identical classes that had previously been loaded by the JBoss class loader. In order to deal with this problem, I experimented some more and found that if I copied all of the TLD files that were in any of the jars in the WEB-INF/lib directory into the WEB-INF directory, then I found that the system was able to find the TLD files, and I no longer needed to set the UseJBossWebLoader property to false. To make my life easier, I developed a small ant file to do the necessary conversion: Note that you need to specify the war-name (the name of the war file you want to convert) and the deploy-dir (the name of the directory to which you would like to deploy the war file). If you just want to modify the war file, you can just invoke the copyTlds target, and you don't need to specify a value for the deploy-dir in that case. Also note that I tried this with one of the the JSTL samples (standard-examples.war), and it appeared to work for that as well. So now we have two work-arounds to choose from: 1) set the UseJBossWebLoader property to false 2) copy the tlds into the WEB-INF directory The bottom line here is that the JBossWebLoader doesn't seem to be looking for TLD files within the jars in the WEB-INF/lib directory. Are there any plans to fix this?

[JBoss-user] [HTTPD, Servlets & JSP] - Re: Standard taglib with jboss 3.2.3, tomcat 5
Can someone tell me which module to download? I've downloaded and compiled the whole lot from CVS 3 times now and I'm not getting any further. I assumed that the module I needed is JBoss-3.2, looking at the list of modules in the jboss root. That wouldn't checkout though. I tried jboss-all, jboss and jboss-3.2, the last of which isn't in the list but I saw someone who'd left a message here about it. The only one that gave me a compilable end-result was jboss-3.2 with -r BRANCH_3_2, but the work-around doesn't work here. I tried jboss-3.2 -r HEAD but that won't compile due to an error with 'thirdparty/xdoclet-xdoclet/lib not found' I can't find any notices saying what I need. It would definitely save alot of time. I have also heard about 'snapshots' of the CVS tree referred to in an old forum msg, but I can't find them anywhere. Do they still exist?

Yes, I read the spec. Glad it works for you with Jetty. I might have to debug this tomorrow with extra logging statements in the TldConfig class, where the action is meant to happen. I can't see anything in the code that gives any hint why it would fail. If I compile the tomcat jars myself from source, can I use them? Or has JBoss modified anything in tomcat?

We're using JSTL 1.1 with JBoss 3.2.3 and Jetty 5 beta2 with no problems. We have jstl.jar in the server/default/lib directory and standard.jar in the WEB-INF/lib directory of each of our webapps. We used a similar configuration for JSTL 1.0 with Jetty 4. Servlet 2.4 containers (i.e. Jetty 5 & Tomcat 5) should pick up tld's in WEB-INF or jars in WEB-INF/lib without any declarations in web.xml - there's a bunch of stuff about this in the 2.4 spec.

my mistake, going on about dtds when I meant tlds. sorry. Anyway I discovered the tlds jboss needs are in the JSTL taglib jars jstl.jar and standard.jar. I've included these jars in both my project WAR and in the JBoss server/default/lib directory already anyway so they're not helping. "fmt" is the first of 8 taglib declarations I've got. Mostly JSTL and struts. I assume that this problem will crop up with all of them. I've been searching and googling like mad but havent found the solution. Would someone please give me a clue?

Ah OK. Thanks for the info. But that URL is not meant to be looked up - it's just meant to be unique and somehow the container can match it against the dtd in a jar somewhere. So it doesn't matter whether my machine is online or not. Or at least it shouldn't. The one that is causing me problems right now: http://java.sun.com/jsp/jstl/fmt has no .tld on the Sun website. It's just a problem because I don't know where the .tld is. The exception message says " http://java.sun.com/jsp/jstl/fmt cannot be resolved in either web.xml or the jar files deployed with this application" I used to have such an entry in the web.xml but about a year ago I removed it for some reason which I shall have to look up, since it's slipped my mind now. This was just with tomcat, not jboss obviously. And of course theoretically it would be nice to be able to specify something (if I have to specify anything) that is container-independent, as opposed to a declaration that points to an internal JBoss directory. After all, it is in my web.xml. I'll see if I can find anything out at jakarta.apache.org/taglibs/ Adam View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=3822650#3822650 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=3822650 --- SF.Net is sponsored by: Speed Start Your Linux Apps Now.

JBoss tries to get the locally from JBoss/docs/dtd, where they are delivered with the server. This is also an advantage for you, as the server can also be started / operated when the network is not up.
