Jetty can't seem to find an inner class

[Brady Diggs]

Hi All!
Thanks in advance for looking at this. If this is not the appropriate forum category, feel free to move it.

Basically what I'm doing is creating a .war file from a couple of classes - one of which is a servlet to post
to a workflow in our application.
Builds ok. Deploys ok. But when I try to browse to the servlet, I get an error saying Jetty can't find an inner class.
I've tweaked and debugged, but I still don't see why this would be happening. For sure, I'm not Jetty expert, and our
Architect has Jetty running as a web server in our application container - sort of a built in web server.
No one has had trouble with it before, so I don't think that's the issue. Anyway, here is the stack trace. If anyone can
help, I would be in your debt for a very long time...

Can you post your code / project tree? I couldn't understand what you meant.

It sounds like class / library version issue or some dependency issue (less likely). Maybe duplicated dependency making the class loader to get confused.

[Paul Clapham]

The most probable reason for that message is that the class that Jetty claims it can't find -- isn't there. You said the project "deploys OK" but that probably just means it deployed without issuing any error messages.

Anyway the JAASBasicAuthenticationFilter$HttpRequestWrapper.class file should be in the same directory as the JAASBasicAuthenticationFilter.class file -- you didn't say you had checked that. I suggest you check.

Thanks Jayr, thanks Paul. I appreciate both of you looking into this.
Paul, you were right. The class wasn't there. Thanks for pointing
this out to me.
