Hi everyone:

I write some insert data transaction code into the action class of strue.
But the jsp page throw these Errors.

my application server is : Tomcat 5.0
my database is MySQL
and also using struts 1.1.

I have no ideal about that errors.
Please somebody help me.
Thanks a lot.

You don't have the jar with javax.transaction.synchronization in your classpath!

I'ts named jta.jar.

p.s. RTFJBGFCM! ;)

I've read your example server.xml and web.xml entries and I STRONGLY advise against modifying your server.xml and web.xml that way. I tried that under Tomcat and couldn't get it to work. I did find a very easy alternative solution. As long as your application creates the configuration, the SessionFactory can be automatically stored in the JNDI context.

You have to use a hibernate.cfg.xml file (I think there is an equivalent hibernate.properties entry but I don't recall it off-hand since I prefer to use a hibernate.cfg.xml file) and use a session-factory tag like so:

<session-factory name="SOMEJNDIURL">
...
</session-factory>

I use dgf:hibernate/SessionFactory and when I create my configuration, it is automatically put into that content (created automatically if it isn't there) by Hibernate. It worked in v2.0.3 and v2.1beta6 for me under tomcat v4.1.24 (and .27 and .29).

I have other posts that detail it plus give examples on how to retrieve it via example JNDI calls.

I'm using Hibernate (both v2.0.3 and v2.1beta6) with Struts (v1.0 and v1.1) without any problems. My configuration includes some transactions, cached queries, cached objects, named parameters, database pooling (DBCP), JNDI binding, facades to hide hibernate from the session, etc. No trouble so far. :)

David

I added the jta package into my appliction library .And adjusted my server.xml amd web.xml.
It's works very well.

^_^

Thanks a billion for your help.
