David Jencks commented on GERONIMO-2678:
----------------------------------------

It looks like Digester can't find the right classes.  I think all that Geronimo can do is assure that the thread context classloader is correctly set to include all the classes in your web app together with the dependencies you declare in your geronimo plan.

Can you:

1. find out what the TCCL is in your jsp page, either by debugging (perhaps in com.unizar.sql.DataSourceCollection) or by logging it.  It should have a name that is recognizably associated with your web app.  If this is not the classloader you find something may be wrong in geronimo.

2. Check that the TCCL can in fact load com.unizar.sql.DataSource.  If it can't there is probably something wrong in how you assembled your web app.

3. Find out what classloader Digester is using to try to load com.unizar.sql.DataSource.  If it's not the TCCL and there is no way to supply the correct classloader in code this might be considered a problem with Digester.

I think you might have trimmed off some of the stack trace.  If these suggestions don't help resolve the issue quickly please supply a more complete stack trace and the version of Digester you are using.  In particular the trace from the underlying exception that the SaxException wraps would be very useful.
