We have recently faced some strange issue with Jboss EAP 7 when we deploy the changes which includes changes to one particular method argument.
After deployment when we're trying to access that method we're getting method not found error and its referring old code which has only one argument.
Can you any one help with this issue. Is this has anything to do with class unloading. Below is one issue referring to class unloading
https://issues.jboss.org/browse/JBEAP-4683
We have also faced same issue probably it could be due to class unloading

I came across problem of cyclic (deploy-undeploy) deployments to WebSphere 7, where uninstalled application leaves dirty workplace. IBM has a fix (PM20642)for it in cumulative updates starting from 7.0.15, but I see no difference. Orphaned folder for business level app and composition unit are still present after undeployment.I'm using JMX admin client for connectivity to the server.
Anyone has any experience in dealing with this issue?
If you're using IBM's fix and it still fails, I would say open a PMR with IBM to help you investigate. It could be their fix didn't work as they expected or maybe the fix pack was not applied correctly. In either scenario way I would say you may want IBM's support to resolve this issue.
If you only have remote access via JMX, then you could try to use $AdminConfig deleteDocument in wsadmin to remove the files/folders from the configuration repository.
I migrating someone else's EJB 2.X app from jboss 3 to jboss 5 (and then maybe onto AS7).
When I do a test deployment of one of the EJBs I am getting this error
org.jboss.deployment.DeploymentException: Could not load class:
at org.jboss.ejb.plugins.cmp.jdbc.metadata.JDBCEntityCommandMetaData.<init>
(JDBCEntityCommandMetaData.java:76)
at org.jboss.ejb.plugins.cmp.jdbc.metadata.JDBCEntityMetaData.<init>
(JDBCEntityMetaData.java:954)...
Googling this stack trace doesn't give me any leads I can work on. As far as I can tell this means that the entity-command in conf/standardjbosscmp-jdbc.xml is wrong but I have no idea what it should be. Looking at the jboss 3 conf/standardjbosscmp-jdbc.xml file doesn't even have an entity-command listed so I assume "default" should be ok, no? I am using Oracle 11g, if that is meaningful and otherwise seem to have no db connection issues. The Oracle datasource seems to be created without problems. This is the very first error in the output. Any clues as to what i should look a to resolve this?
Are you sure you build everything against JBoss 5 libs? This could be a build problem...
I have started working with ZK recently. I really like the framework but I am having a lot of problems in configuring it to work correctly with Websphere Application Server v8.0. Namely, I am developing an EJB application with accessing the database via JPA entities and using the ZK framework for GUI. I am developing the application using the Rational Software Architect 8.5.
When I start working on a fresh ZK project in a fresh workspace and server profile everything seems to be working correctly. However, after some time I start having strange problems. I think the problem occurs in the moment when ZK tries to initialize my ViewModel class. I do not get any exceptions or errors, but get the timeout message in my browser: "The page or component you request is no longer available. This is normally caused by timeout, opening too many Web pages, or rebooting
the server."
My ViewModel initializes by resolving the EJB bean I am using for business logic. That normally works, but as I said, after working for some time on the project, or after restarting my computer the ViewModel object cannot get initialized and the timeout error appears no matter what I do (when ZK tries to bind a variable or when I fire an event needed to be handled by my ViewModel. As before, I do not get any additional errors or exceptions.
Has anybody already had this problem? Is there a solution? Can I change the configuration of my server or ZK to avoid this problem?
Thank you.
Seems that I have solved the problem myself. I was using internal Rational Software Architect (Eclipse) browser which apparently has problems handling ZK sessions. When I switched to Firefox, the problems I explained stopped appearing.
I post this merely as a reference for others that might end up being in the same situation and since I spent almost 3 days trying to figure out the root cause of the problem, I thought it would be a good idea to post the solution here.
My situation was as follows:
I tried to build a deployment package for a .net application and got TypeLoadExceptions, FileNotFoundExceptions (regarding DLLs), Side-By-Side configuration errors, etc. once I tried to run it on a vanilla test machine.
[edit]: stackoverflow won't let me answer my own question within 8 hours of it being posted, the answer follows in ~8 hours ;)
The problem was that one of the dependency projects of my application was set to "Debug" build in the Visual Studio configuration manager, therefore the debug dll of the dependency ended up being used for release builds as well. On any development machine this was no problem after all since all debug runtimes were available.
On the vanilla test machine however only the release runtimes were present which caused so much trouble to me and gave me unmeaning exceptions that lead me to so many wrong directions via google, etc.
In my case it was SlimDX that was set to build a debug build in the VS configuration manager, even when doing release builds. Since SlimDX makes use of the VC runtimes I got the above problem, but this could happen with any .net assembly that uses the VC runtimes.
I hope this will eventually safe someone some hours ;)
I use the Hot Swap java debugging feature with web app on Tomcat. After some class signature change, I got "Hot Code Replace Fail" Eclipse dialog - I understand that.
What I want in such case is to republish the application (I can do that) and work with the newly deployed code. However the debugger stil complains, until I restart the server. Because other apps and long startup I don't want that.
Is there a way how to tell to the debugger, that there is the new class version already reloaded in a new webapp classloader and that it is save to continue?
Thanks.
Why don't you try with JRebel?
JRebel is a JVM Java Agent that integrates with application servers, making classes reloadable with existing class loaders. Only changed classes are recompiled and instantly reloaded in the running application.
JRebel plugs into IDEs and build systems. Classes and static resources are loaded straight from the workspace.

There is a old PHD project. The guy who made it was brought by Oracle but his work didnt made it to the Java 8 and hopefully will be seen in Java 9 but is more likely to be in Java 10. There is a new Version of this for Java 8 I guess. I havent tried it yet.
My Original Question for additional information: Advanced Code Hot Swapping in JDK 8?
And the Project page on Github: https://github.com/dcevm/dcevm
With this you can hot replace almost any class change freeing you from restarting the JDK ever after. (beside sideeffects for static objets and singletons but that would be logical)
Did you try Server Options - Serve modules without publishing along with Publishing?
Also not sure what you are saying about other apps.
