I am using OJB rc5. Everything is fine when I use it
for stand alone program. But when I try to use it in a
web application (applciation server is resin 2.1.10),
I got following error. From the log, we can see that
there is a NullPointerException at
org.apache.ojb.broker.metadata.RepositoryXmlHandler.getIsoLevel(Unknown
Source) and from the debug message we can see that
isolation-level: null.
If I manually add isolation-level attribute to each
class descriptor element in repository_internal.xml
and all included repository_user.xml's, then it works.
I don't think there is any document saying that we
need to change repository_internal.xml. I am wondering
whether anybody has ever had the same problem and
what's the real cause and the soultion for it.
Thanks in advance.
