Re: TOMCAT3.2 BUG
You're not alone with this problem. I was just involved in a couple of threads on this subject in the JBoss Users mailing list, but everyone who participated seems to have the same problem. Here's a link to one thread: http://www.mail-archive.com/jboss-user@list.working-dogs.com/msg09704.html I finally worked around the problem by putting everything that would normally be in WEB-INF/lib and WEB-INF/classes into the main Tomcat classpath. This works, but I'd still like to find out what the problem is...Tomcat? JBoss?, or something else. Possibly confounding factors in my setup include using JBuilder 4.0 to run both Tomcat and JBoss, and am using Struts. Don't know if these could be affecting the outcome at all because I haven't tried a different setup without them. Thanks for any help anyone can provide.

Re: TOMCAT3.2 BUG
I have tried to put a similar question in this newsgroup, without getting any answers. Also tried other places, like the discussiong forum at Sun. This is somewhat curious, because hopefully we are not the only ones trying to access EJB's from JSP-pages. Fact is: The classes (and other resources, like jndi.properties) needed when accessing remote objects like EJB's from JSP have to reside in the classpath used when Tomcat is started. It does not work if they are put under the web-application WEB-INF catalog. (BTW, this also applies eg. to the JRun 3.0 JSP-engine.) I think the problem is that different classloaders are involved here. If you put the class-definition for eg. an Enity Bean in a jar-file that is placed in WEB-INF/lib, an Exception is thrown from java.net.URLClassLoader when the remote object is received from the server (because the class defintion is not found). Putting it in Tomcat's lib-directory "solves" this problem. Similar problem is with the classes you mention. Question is: Where do the problem belong? Should it be posted as a bug in JDK 1.3? Or should JSP-engines like Tomcat and JRun handle the situation? I'm not sure, and it would be interesting to hear other opinions on this issue. erik --- shiva nand tripathi [EMAIL PROTECTED] skrev: I am integrating Apache Web server, Tomcat and Jboss (EJB container).

RE: TOMCAT3.2 BUG
Not having tried this since I don't use JBoss, here is my thought. The only difference between putting it in the main tomcat classpath and putting it in WEB-INF/lib is the class loader that is used (javas versus tomcats). Since I have quite successfully used tomcats in WEB-INF/lib, I am guessing that maybe there is something a little but different about the jar file. Maybe you should try to unjar the package, and then rejar it yourself using no compression and no fancy options (or just leave it unjarred in the WEB-INF/classes). Hope this helps, Paul -Original Message- From: Rick Horowitz [mailto:[EMAIL PROTECTED]] Sent: Saturday, January 27, 2001 1:00 PM To: [EMAIL PROTECTED] Subject: Re: TOMCAT3.2 BUG You're not alone with this problem.

RE: RE: TOMCAT3.2 BUG
Thats really unfortunate. You should post this in the bugtracker. It seems that this is a common problem. I'd post it in the jakarta/tomcat one as JBOSS seems to be a bit less communicative. On that subject (and somewhat off topic) what all exact files does one need to deploy an EJB. I keep getting some obnoxious error about deployment.cfg not existing (right after it deleted it). I had a jar and a ejb-jar.xml in its META-INF and no luck. -Original Message- From: shiva nand tripathi To: [EMAIL PROTECTED] Sent: 1/27/01 1:03 PM Subject: Re: RE: TOMCAT3.2 BUG Thanks for replying.
