Package name conflicting with class name

[lukascz]

I found following problem in JBoss 7.1.1.Final. When I try to deploy following package

com.company.model.businessobjects.contest

and further I have class com.company.model.businessobjects.Contest

It fails on

Caused by: java.lang.NoClassDefFoundError: com/company/model/businessobjects/contest (wrong name: com/company/model/businessobjects/Contest)

It seems it's not able to handle class that has the same name as package

Is this a bug or expected behaviour?

Thanks.

I'm not sure, but if you use Windows it might be an issue that the filesystem does not respect uppercase.

I'm using MAC

See also https://community.jboss.org/message/743677#743677.  To that post, I attached a small sample app that demonstrates the issue.

Lukas,

Did you find a fix for your problem? I'm getting the same in JSP - The import .... cannot be resolved error. I too have a package and class with same name and looks

like JBoss 7.1.1 couldn't import the correct file.

I don't think it's an universal bug. JBVFS-170 appears closed (and included in 7.1.1.Final) and I just tried the same scenario (7.1.1.Final + Win + Java7) and had no problem deploying a WAR with a package name matching the name of a class...

Nicklas,

I created a simple web app and recreated that problem. I have attached that web application.

Environment:

OS: Windows7 64 bit

JRE: Java 1.6.0_34 64 bit

JBoss: 7.1.1.Final - Standalone

I just renamed the package...

[nickarls]

Ah yes, it deployed fine but I got the error when accessing the context root (thus triggering the compile)

[syau]

Can you please be more specific?

'.. I got the error when accessing the context root ..', are you saying when you accessed,

http://localhost:8080/webApp/ - you got the compilation error, later when you accessed,

http://localhost:8080/webApp/index.jsp , it was OK. For information, I still get that error.

[nickarls]

Only tried the context root, I assumed if it didn't compile it was never going to be available.

Both Windows and MacOS use case-insensitive/case-preserving based file systems.

It is not possible to have two objects in a directory whose names differ only by character case on these operating systems.

This is how its available in the current windows environment (folder - package & file - class with same name) in Production and it works fine in Weblogic. What would be the best solution in

JBoss to fix this? Issue JBVFS-170 says '...When using JSP a class name Toto.class may hide a package toto. In AS5/6 it is fixed using -Djboss.vfs.forceCaseSensitive=true ... ' .

I tried adding -Djboss.vfs.forceCaseSensitive=true in the standalone.bat, but doesn't seem to work.

I don't think it has anything to do with VFS.

If you deploy your example as an exploded WAR you get the same problem, and I don't think VFS is involved in this case (standalone/tmp/vfs is not touched at all).

Seems like a jasper problem (aka Apache Tomcat).

It works on WebLogic because it does not use Tomcat as far as I know.

We should be able to test it by cranking up a Tomcat distribution and testing your example in it...

[sfcoy]

Hmm.

Works fine in Tomcat 5.5.4 which I happened to have lying around.

Also works fine in Tomcat 7.0.30.

JBoss 7.1.1 appears to be using 7.0.3, but I suspect that theory has been blown out of the water.
