Hi!

I know there's a VM parameter called EJBCmpMaxBlobSize that you can use to
set the max size of blobs for the CMP. But I'm almost sure the default max
was 10000 bytes and that the container would give a hint in the Exception
about
the EJBCmpMaxBlobSize if it had been exceeded. Well it probably doesn't hurt
to try EJBCmpMaxBlobSize to see if it helps.

If you are running the container in JBuilder you add it as a VM parameter
like this

-DEJBCmpMaxBlobSize=100000

These can be set it in the run configuration on the EJB tab or in project
properties in the Run -> EJB tab.

If you're running in the appserver then start the AppServer Console and
right click on your AppServer, chose Edit Properties and click on the
Configuration File
tab. You can now add a new line with

vmparam -DEJBCmpMaxBlobSize=100000

in the modifiable section of the configuration file.
