Hi,
I have searched the mailing list for an answer on this one.
I noticed that several other entries, without any replies.
One thread suggests it has something to do with connection pooling
or an incorrect class loader....? Anyway here is what I did.
I had a neat little BMP entity bean, which worked fine with Oracle 7.
Then I switched over to Interbase 6.0 and everything seemed okay.
At least modifying en removing rows from the database table does work.
But when I tried to call the home.create() of this
bean. Al of a sudden I got an Exception throw at me. In the
log file the trace trace said:

[Bean Cache] Resized cache for bean Country: old size = 50, new size = 65
Country is the BMP bean, CountrySession is a stateless session bean from
which I am calling
the home.create() method of the BMP entity bean.
Another thing that puzzles me are the following lines in the log file. Are
they possibly related?
[Configuration] Detected JMX Bug: Server reports attribute 'JDBCUser' is not
writeable for MBean 'DefaultDomain:name=Interbase,service=XADataSource'
[Configuration] Detected JMX Bug: Server reports attribute 'TimestampUsed'
is not writeable for MBean
'DefaultDomain:name=Interbase,service=XADataSource'
[Configuration] Detected JMX Bug: Server reports attribute 'JDBCUser' is not
writeable for MBean 'DefaultDomain:name=InstantDB,service=XADataSource'
[Configuration] Detected JMX Bug: Server reports attribute 'TimestampUsed'

[Configuration] Detected JMX Bug: Server reports attribute 'JDBCUser' is not

I am lost...... Help :-(
