RE: Classpath issues when calling ejb services (from a custom task)
Hi,
Thanks for replying :)
I'm not actually using the xdoclet task - I am trying to make a "custom"
task of my own, which needs to call some functions on a remote stateless
ejb.
I've made some progress by setting a new classloader inside my task, however
I've now got a class cast exception when I narrow the remote object back to
the ejb interface... which is odd because the same calls made from a junit
test run from ant works fine.
I'll keep persevering for a bit yet.
Cheers
Andy

RE: Classpath issues when calling ejb services (from a custom task)
Posted by Andy Redhead <al...@btopenworld.com>.
Ok, I admit defeat...
if I change the class loader used in my custom task I get class cast
exceptions when I try to narrow remote object references - which I guess is
because things are going across multiple class loaders.
Everything works if I use a load of -lib statements on the command line that
starts ant and I don't use classpath or classpathref elements within my
build script.
I would be interested to know if anyone else manages to find a way of using
classpath elements in a custom task that calls remote ejb services.
Cheers
