Re: error parsing repository.xml

[Armin Waibel]

Hi Larry,

hmm, stack trace says:

Caused by: org.apache.ojb.broker.metadata.MetadataException: Can not 
read repository class descriptor data, using repository: repository_user.xml

and

[org.apache.ojb.broker.metadata.RepositoryXmlHandler] DEBUG:   > 
class-descriptor
[org.apache.ojb.broker.metadata.RepositoryXmlHandler] DEBUG: 
isolation-level: null

Seems your parser returns 'null' when attribute is not set or do you set 
the class-descriptor 'isolation-level' attribute?

RepositoryXmlHandler does not check for 'null', seems other parser 
return an empty string instead of 'null'. Will check in a fix ASAP.

regards,
Armin

Please ignore the last posting, it was the same file by mistake :-(  The 
attached file contains the stack trace with debug information enabled.

Thanks.

I've got a very strange error cropping up when I try to run a simple 
test program for OJB.  Note that I can build and execute the JUnit 
tests using the distribution and things work fine.  However, when I 
construct a simple batch file to include all the jar files from the 
ojb "lib" directory and add in the directory that contains the 
properties files I get a NullPointer exception during the parse due to 
"isolation-level" being null.  Now this appears to be an internal 
table lookup, so I'm not sure how it can fail.  Also, I copied the 
repository.xml file from the OJB distribution as my starting point, so 
the isolation-level attribute is being properly specified.  I've 
attached the debug output and the exception trace below. Any help or 
insights would be appreciated.

Thanks.
