Hi!
I have successfully deployed a web app on Virgo 2.1.0.
All my bundles are installed and started successfully and in my log I see the url mappings to my controller classes.
I have configured Spring Security 3.0.2.
When I access my application in my browser, I expect to be forwarded to the login page.
But I get a:

According to the JavaDoc: "LinkageError indicate that a class has some dependency on another class; however, the latter class has incompatibly changed after the compilation of the former class."

Do you have Spring binaries bundled in your web application? It seems so from the stacktrace (Spring security?).

I put the spring security binaries in the 'usr' folder.
Do you (or anyone??) have an example of spring security on virgo?

Now it works!
I added org.springframework.security.web;version="[3.0.1, 3.1)",
org.springframework.security.core;version="[3.0.1, 3.1)"
to the Import-Bundle list and dropped a couple of extra jars into the 'usr' folder (com.springsource.org.apache.log4j-1.2.15.jar and com.springsource.slf4j.log4j-1.5.10.jar).

Not quite sure what did the trick.
But I am not going to mess around with it to find out Razz

I'm glad the problem is solved. If you want to get to the bottom of the problem, read on.

The loader constraint violation shows that two bundles are picking up different versions of the class org.apache.commons.logging.Log. I haven't seen that issue before in Virgo. The crux of this issue is which class loaders are being used to load the different versions of the class. If you want to investigate with a debugger, try to find the defining class loaders for the two class instances, although you'll need a good understanding of class loading to make progress.

Alternatively, if you can package up a (simple) test that reproduces the problem, please raise a bug for us to look into.

Can this be caused by having different version of com.springsource.slf4j.org.apache.commons.logging in usr?

Perhaps, but I think this would need to be combined with something like a missing uses constraint as well.
