Category: None >Group: v3.0 Rabbit Hole Status: Open Resolution: None Priority: 5 Submitted By: Giles Paterson (gpaterson) >Assigned to: Scott M Stark (starksm) Summary: EAR file class scoping problem Initial Comment: JBoss: 3.0.4 OS: Windows 2000 Server Java Version: java version "1.3.1_01" Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1_01) Java HotSpot(TM) Client VM (build 1.3.1_01, mixed mode) This bug report has been created at the request of Scott M Stark in response to my posting to the jboss-user mailing list Here is the content of the email I sent to the mailing list: --- For the full details, take a look at the following forum thread: http://www.jboss.org/forums/thread.jsp?forum=47&thread=24806 Basically, I have an EAR file that is structured like this: main.ear: some_ejbs.jar some_more_ejbs.jar a_web_app.war lib/ third_party_libs.jar common_code.jar META-INF/ application.xml This jar was working perfectly under Weblogic 6.1, but just doesn't want to play when ported to JBoss 3.0.4 (Yes, JBoss specific deployment descriptors have been added to the various EJB jars). It is worth noting that the MANIFEST.MF files for the EJB Jars and the War file reference various third party and common jars in the Class-Path element. Initially I was encountering all sorts of IllegalAccessErrors and NoClassDefFoundErrors, and adding a jboss-app.xml file to the Ear to scope the classes didn't help at all. I was making some progress by manually adding various jars to the JBoss start-up classpath but that wasn't a great solution. Finally I tried unpacking the EAR file into a subdirectory of the deploy directory and the application suddenly started working (with no additional jars in the JBoss start-up classpath). However, if I removed the jboss-app.xml file from the expanded directory, the application would stop working and give me IllegalAccessErrors again. This suggests to me that Class scoping doesn't always work in 3.0.4 if the application is packaged in an EAR file, but it does work if the EAR file is expanded out into a directory. After some further trawling of the mailing list archives, I believe this may be related to the fact that my EJB jars, reference the same common and third party jars in their MANIFEST.MF Class-Path entries (There was a thread concerning this back in August/September http://www.mail-archive.com/[email protected]/msg20584.html ), and possibly to bug #602828 Currently, I am satisfied with deploy my app as an expanded EAR directory, but I would prefer to use an EAR as it simplifies the deployment process. Does anyone have any comments or suggestions concerning this? I haven't had a chance to delve into the JBoss code yet, but I'm intrigued as to why the Class loading works differently for Ear files as compared to expanded directories. --- I have been unable, so far, to create a simple test ear that recreates the problem, so I have instead attached a UCL log file. I will attempt to create an example EAR file and upload that when I get a chance. ---------------------------------------------------------------------- >Comment By: Scott M Stark (starksm) Date: 2002-11-23 18:30 Message: Logged In: YES user_id=175228 The trace log shows no NoClassDefFoundErrors and will not show any IllegalAccessErrors so what are the corresponding stack traces seen in the server log so I know what classes are involved. ---------------------------------------------------------------------- Comment By: Giles Paterson (gpaterson) Date: 2002-11-20 03:21 Message: Logged In: YES user_id=124102 Well, the zipped UCL log was too large to attach here, so I've emailed it to Scott Stark instead. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=376685&aid=641155&group_id=22866 ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Jboss-development mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-development
