I'm using JTA transaction
and try to manage my transactions myself (many independent updates)
using seam 2.0.0.ga
<core:init debug="@debug@" jndi-pattern="@jndiPattern@" transaction-management-enabled="false" />
conversation-timeout="12000000" -->
<core:manager concurrent-request-timeout="5000000"
conversation-timeout="200000000"
conversation-id-parameter="cid"/>
i use following code to start the transaction
UserTransaction tx=null;
tx=Transaction.instance();//get the UserTransaction from seam
// transaction handling
try {
if (tx!=null) tx.begin();
} catch (Exception er )
{errcod=er;
String errmsg=er.getClass().getSimpleName() +" err: "+ er.getMessage();
log.error(env+" starting transaction failed "+ errmsg);
}
try {
I'm handling the transaction here ;
try {
em.flush();
} catch (Exception er )
{errcod=er;
String errmsg=er.getClass().getSimpleName() +" err: "+ er.getMessage();
log.error(env+" Flushing the transaction transaction failed "+ errmsg);
}
try {
if (tx!=null) tx.commit();
} catch (Exception er )
{errcod=er;
String errmsg=er.getClass().getSimpleName() +" err: "+ er.getMessage();
log.error(env+" Commiting transaction failed "+ errmsg);
}
} catch (Exception er) {
String errmsg=er.getClass().getSimpleName() +" err: "+ er.getMessage();
log.error(env+" transaction error "+ errmsg);
try {//rollback cover
if (tx!=null) tx.rollback(); //if (!Transaction.instance().isActive())
else if (ses!=null) txn.rollback();
else em.getTransaction().rollback();
} catch (Exception erx)
{errcod=erx;
String erxmsg=erx.getClass().getSimpleName() +" err: "+ erx.getMessage();
log.error(env+" Rollback transaction failed "+ erxmsg +" From "+ errmsg);
}
}
if (ses==null)
{ if (!(em.isOpen())) log.info("em session closed !");
}
}
I'm trying to trap for every error
I'm failing on tx.begin();
how can I create the transaction ?
