[Wonder-disc] ERChangeNotification and exolab problem

[Simon M. <sim...@ma...>]

Hi Jean-Francois -

Many thanks for this. I checked my topic names and all seemed ok, but =20=

i've dug a bit further and think my problem is with exolab.

When i initially added the ERChangeNotification framework to my app =20
it wouldn't run due to a fatal exception =20
"java.lang.NoClassDefFoundError: org/exolab/core/util/URI=20
$MalformedURIException" (full stack trace below).

As this suggests the framework was looking for exolabcore-0.3.7.jar =20
and couldn't find it i dropped the exolab jar into my /library/java/=20
extensions and hey presto no error and everything loads fine.

However, with the exolab jar in my java extensions OpenJMS isn't =20
starting up properly (hence no notifications).

I can trick it all into starting up Ok by starting OpenJMS without =20
the exolab jar in my java extensions, and once OpenJMS is up and =20
running I can put the exoblab jar back in my java extensions and run =20
my webobjects app and all works fine - notifications are being sent =20
and received across different applications perfectly.

But this leaves me in a catch 22 as i want to run openjms on the same =20=

server as the apps.

Any suggestions on what I should do ?

Thanks, Simon
