Hi Jean-Louis,
thanks! I tried this (with a simplified version of your regex) and now
weblogic.jar is in fact no longer loaded as client app. But the problem
is still there, because nevertheless weblogic.jar remains in the
classpath and so the SAXParser still interferes. The cause of the
exception now looks like this:
Caused by: org.xml.sax.SAXParseException: Premature end of file.

The OpenEJB startup has shown the following lines so you can see that
the regex has been applied:
....
INFO - Using 'openejb.deployments.classpath.exclude=.*/weblogic.*'
INFO - Using 'openejb.deployments.classpath.filter.descriptors=true'
INFO - Inspecting classpath for applications: 48 urls. Consider
adjusting your exclude/include. Current settings:
openejb.deployments.classpath.exclude='.*/weblogic.*',
openejb.deployments.classpath.include=''
....
I have already tried to start tailoring the weblogic.jar (removing the
SAXParser) but this lead to other errors. I think I would need a way to
define, that the OpenEJB XML Parsing classes come before the
weblogic.jar in the classpath. Is there a way to achieve this? Or are
there any other ideas?
Many thanks in advance,
Stephan

Hi Stephan,
Could you try excluding this jar?
Actually, OpenEJB looks for Java EE components for each jars.
I guess it's not required for weblogic.jar so you could exclude this jar
(bootstrap will also be faster).
Have a look to
http://openejb.apache.org/3.0/application-discovery-via-the-classpath.html
http://openejb.apache.org/3.0/application-discovery-via-the-classpath.html
openejb.deployments.classpath.exclude=.*/weblogic(-[\\d.]+)?.jar(!/)?
openejb.deployments.classpath.filter.descriptors=true
Can you give it a try?

Hi,
I am just wondering if anybody has ever had the same problem, that he
had to access a remote EJB deployed on a Weblogic (here 8.1.6) Server.
My problem is, that as soon as I put the evil weblogic.jar (which I need
for communicating with that remote EJB via the t3 protocol) into the
build path of my eclipse jee5 projects, then OpenEJB doesn't come up
anymore.
The problems seems to be, that there is a SAXParser in weblogic.jar that
comes into play when OpenEJB wants to read the persistence.xml from my
ejb/jpa module (see the cause of the stacktrace below).
Has anyone managed to get rid of that or an idea how it could be solved?
