NOTE: For fastest resolution when reporting an issue, please provide attach
example project or file *with sources* that reproduces the problem.

What steps will reproduce the problem?
1. create app1 that doesn't use pretty-faces;

What is the expected output? What do you see instead?
The application is excepted to run with no problems. However, 
nullPointerException is thrown. It says it can't find the Pretty Filter; 
but this filter is not mapped in this application's web.xml because it does 
not uses pretty-faces.

The CSS problems were being caused by different versions of RichFaces in both 
sides.
I was using 3.3.2 in one of the apps, and 3.3.0 in the other.

However, I still have the issue about the filter and the "mixed" contexts.

Searching for an answer in the glassfish forum

Can you explain what you mean by "mixed contexts?", I think I have an idea 
about ServletContext being maintained in PrettyFilter, but I'm not sure it's 
the issue you're talking about.

Sure.

Each web application is supposed to have its own context, right? So, they do 
not see each other directly. In this case, jars and filters in one application 
are directly affecting the other app.

When I said "'mixed' context", I meant that it looks like both apps have the 
same context.

Does anyone know how to fix this problem?

Are there any news on this issue? Did somebody find a fix? I don't think it is 
a PrettyFaces problem as we don't work with any "dirty tricks" like static 
variable references, so it sounds like a Glassfish issue. It would be great to 
get any kind of feedback.
