Not supported in managed environment
Hi,
I am using MySql database and I got "Not supported in managed environment'
exception when borker.beginTransaction() method. Does anybody knows what's
wrong?
Thanks.
Best regards,

How to get Transaction Manager Factory
Posted by Leon <le...@hotmail.com>.
Hi,
A quick question.
In order to find the transaction manager, I set up transaction manager
property to WeblogicTransactionManagerFactory. How can I get the instance of
it, like look up or just new an instance?

Hi Leon,
in managed environments the transaction demarcation
should be done by the container (cm-tx) or using
JTA-UserTransaction.
Hence OJB does not allow OJB-tx demarcation.
This behaviour is managed by the 'ConnectionFactoryClass'
attribute in OJB.properties

Armin

Re: How to handle SQLException in OJB?
Posted by Leon <le...@hotmail.com>.
Hi Michael,
I tried do that but pbx.getCause() is not PersistenceBrokerSQLException.
pbx.getSourceException() is instance of SQLException and the cause is
"Duplicate entry 'xxxxxx' for key2". I can use this message to do exception
handling. However, I was wandering if it is a generic way to find the
details of SQLException?
Thanks.

Hi Leon,
It looks like you're logging level is not set correctly - you need to set
the logging level of JdbcAccessImpl to FATAL because the printStackTrace
occurs when set to ERROR or below.
If you're using the default logger (PoorMansLoggerImpl), then you want to
change your logging levels in OJB.properties:
# Note that this is NOT JdbcAccess, but rather JdbcAccessImpl
org.apache.ojb.broker.accesslayer.JdbcAccessImpl.LogLevel=FATAL
After this, you can catch a PersistenceBrokerException and check whether it
is an SQL exception or not:
try
{
Collection allProducts = broker.getCollectionByQuery(query);
}
catch (PersistenceBrokerException pbx)
{
// The PersistenceBrokerSQLException is nested in pbx and the
// SQLException is nested in that (ie pbx.getCause().getCause())
if (pbx.getCause() instanceof PersistenceBrokerSQLException) {
System.out.println("SQL problem " + pbx.getCause());
}
}
Cheers,
Michael

It could be from the logger - have you disabled output from that? (or at
least set the log-level to something high-ish)
The default logger (PoorMansLoggerImpl) will print a stack trace if a
Throwable is logged (perhaps log4j does as well), so this may be your
problem.
Which code is causing the problem? Can you give a sample? Are you using
PersistenceBroker or ODMG or JDO?
Cheers,
Michael

I already tried that but it is unreachable catch block.
Thanx.

This doesn't work? :
try {
// DAO code here...
} catch (SQLException sx) {
throw new MyApplicationException("Had an SQL error.");
}
What have you tried already?

How to handle SQLException in OJB?
Posted by Leon <le...@hotmail.com>.
Hi,
In the case of inserting a record with same key value, a SQLException of
duplicate entry is thrown in implementation of OJB. How can I catch this
exception in my DAO object so that I can throw my application exception?
Thanks.
Best regards.
Leon
