Hi
On my ZK Webpage I use zhe ZKHibernateUtil to access the session. It looks like everything works fine.
But after a day or a couple accesses from different sessions, the database access fails.
I run ZK 2.1.3, Hibenrate 3.2 on Tomcat 5.5.20.
The catalina log:

It seems that the hibernateUtil is providing me closed connections after a while.
My DAO looks like this:
public List getAllPhotosFromGroup(String grp) throws DatabaseException {
try
{
Criteria
c = HibernateUtil.currentSession().createCriteria(Photo.class);
c.add(Restrictions.eq("grp", grp));
c.add(Restrictions.eq("size", "s"));
c.addOrder(Order.asc("number"));
return c.list();
}
catch (HibernateException hibernateException)
{
throw new DatabaseException("Could not get photos by group: " + grp, hibernateException);
}
}
I do nothing like session open/close commit in my code.
Thanks for your help.

1. What is the log message after this?
"Caused by: com.mysql.jdbc.exceptions.MySQLNonTransientConnectionException: No operations allowed after connection closed.Connection was implicitly closed due to underlying exception/error:"
2. Do you use Spring framework in your application? If not, don't include the OpenSessionInViewListener. It is supposed to be used with Spring's OpenSessionInViewFilter.
3. You have to do the Hibernate commit and close in your code(Using the
HibernateUtil) if you are not using Spring's OpenSessionInViewFilter, or the connection pool will be run out. Please see Hibernate's example code as a hint.
ZK does not "ADD" anything on that. It simple "enable" the Hibernate to work seamlessly with ZK.

Thank you Henri
No I don't use the Spring framework.
I removed now the OpenSessionInViewListener, added Transaction begin / commit and session.close() (I read your ZK + Hibernate example but missed the part with Spring, that's why I was a bit confused.)
It seems to work as before (but hopefully without resource leaks). Time will tell. But I have a really good feeling know :-)
Thank you for the fast support. I'm also fine now with the CSS stuff that you answered in the other message.

The following statement I made is not correct. Sorry. I screw up this time :(
"2. Do you use Spring framework in your application? If not, don't include the OpenSessionInViewListener. It is supposed to be used with Spring's OpenSessionInViewFilter."
The above statement is not correct. The ZK's OpenSessionInViewListener is supposed to be used with the HibernateUtil.currentSession() thread strategy. It in fact plays the same role as Spring's OpenSessionInViewFilter.
That is, Andrea, there should be some issues in your original codes.
can you provide the log message after this?

Hi Henri
Yes here it is. Without the OpenSessionInViewListener it was also not working correctly.
Here the missing part of the exception:

Where did you deploy the zkplus.jar? In shared/lib, WEB-INF/lib, or both?

in shared/lib AND in WBE-INF/lib.

Hi, Andreas,
Can you run your program on Postgresql or Hsql to test if this is db related?
Or if you can send me your code (henrichen <at> potix <dot> com) that I can test it here.

Hi Henri
I switched to Datasource instead of a JDBC connection and it seems to work now as expected.
To me it looks like the OpenSessionInViewListener didn't handle the sessions correctly with jdbc.
I removed the connection.pool_size to 3 so I could easy reproduce the error with jdbc-connection by opening a browser for more than 3 times. But with Datasource it worked. I will do some more testing and keep my web-server up and running for a couple of days to see if it is stable over time.
So now I have the 3 listeners for Hibernate in the zk.xml, the resource definition for the Datasource in the web.xml and the context.xml for tomcat with the datasource resource configuration.
Thanks anyway.

OK. I will test the issue here. Thanks.

Andreas,
I have tested with my own example with the same configuration as yours but I cannot replicate the issue.
If possible, I would hope you can provide your testing codes to me ( henrichen <at> potix <dot> com ), so I can test it here.
