Transaction Timeout with session bean and JavaMail
James Lawless
Hello,
I am using a stateless session bean to send mails using JavaMail.
Every time the application needs to send a mail it calls this session bean which
looks up the mail properties from its environment entries and then sends using
static method Transport.send()
All was fine and dandy in test but since deploying to production I am getting
an exception, weblogic.transaction.internal.TimedOutException (full stack trace
below). I have another application deployed on the same app server which uses
JavaMail and the same mail server which seems to be working fine.
The other (non-EJB) mail application, which works, reads the mail properties from
a properties file rather then from environment entries.
I have read that I may change the transaction timeout attribute in the deployment
descriptors or on the console which I am about to try but even if that works I
would like to know why the transaction is timing out. Is it likely that looking
up the JNDI tree for the env-entries is the cause of the timeout?
Or could the problem be related to the mail itself?
And what's transactional about sending a mail anyway? Is there something I can
change there?
Thanks,
James
