hmm, really strange!
On the given persistent object obj.toString() was called,
could this be the problem?
Which logging implementation in OJB.properties do you use?
regards,
Armin

Hi Armin,
I have actually been analyzing it deeper it occurs in
org.apache.ojb.broker.accesslayer.JdbcAccessImpl class in the
executeInsert() method when the line
"logger.safeDebug("executeInsert",obj);" is called (line 193).
I can only assume that the safe debug is causing a thread deadlock (it
event makes the eclipse debugger go moggy).
I turned my logging back to info and not it works fine.
For background info I am using OJB from within Tomcat and the sample
code is
try
{
if ((db == null) ||
(!(db.isInTransaction()))||
(delegate = null) )
startOJB();
if (delegate == null)
db.store(object);
else
delegate.add(object);
}
catch (Exception e)
{
logger.error(e.getMessage());
throw createExceptionWithMessageHolder(e);
}
finally
{
if ((db != null)&&(!db.isInTransaction()))
releaseOJB();
}
Let me know if you need more info
Regards,
Julian

Hi Julian,
can you post more info?
do you use OJB standalone?- used environment?
do you tried run your test code in standalone OJB?
code snip of your test code.

Armin

Hi,
I am doing a 1:m insert of an object. When I step through the code using
the debugger it works fine, however if I just let it run normally OJB
hangs
This is how my repository.xml looks
