[jetty-users] "Absent code" errors while running embedded jetty app in e

[Kristian Rink <kawazu428@xxxxxxxxx>]

Folks;

unsure what to make of it: Meanwhile, my embedded jetty application 
builds and runs the way I want it, and the way it needs to do until I 
got rid of the embedded war container. However, there is one issue still 
confusing me: The project is a maven artifact developed and, at times, 
ran from within Eclipse. Situation:

- The project builds well in and outside Eclipse. Unzipping and running 
the outcome from the command line works perfectly well.

- Running the launcher class from within Eclipse, however, seems good at 
first but fails as soon as I try to access the webapp, in exceptions 
like this:


[...]
java.lang.ClassFormatError: Absent Code attribute in method that is not 
native or abstract in class file javax/servlet/jsp/jstl/core/Config

I have spent quite some time messing with the Eclipse launch 
configuration but failed to find what might be messed up here. Ideas, 
anyone?

TIA and all the best,
Kristian
