Hello,
Tomcat block with Hibernate on:

sessionFactory_ = new AnnotationConfiguration().configure().buildSessionFactory();

this is the log

--- HERE IT BLOCK , TIME OUT SET UP TO 500 SECONDS, BUT NOTHING !

why is it possible ?

My Best Regards

Hi,

please report the stacktraces of the blocked java process, so we can see exactly where the thread hangs.
The stacktraces of all java-threads can be extracted either by using the jstack utility, JConsole or send a kill -quit signal (on a Posix operating system).

Hy Thanks

I think it is blocking on the missing class (don't know why) AnnotationConfiguration
yet I added to the class path all the hibernate jars

sorry for the pics to the bottom of my image
but it is an advertising of its provider

found the TEXT way

So now I understand not anymore what's exactly your problem.
The ClassNotFoundException or the blocking thread?
Usually an Exception does not block a thread so this 2 things have nothing in common.
Also usually a ClassNotFoundException reports in the message which class was not found.

Please look also in the log files of tomcat, maybe there is the ClassNotFoundException wyith full stack-trace.

Sorry
it block this is the stack, hope usefull

HI
it seems it blocks on the connection !

We actually moved from XP to Windows 7 and using Tomcat 6
previuosly we used tomcat 5 and win Xp

and it from XP it is still working


best

I also update the jdbc to jdbc4

Infact I don't think it is the db, but the libraries
Even we the db down it blocks

Hi Fabio,

I think the problem stays in the JDBC parameters you use to connect to your MS-SQLDB.
As I understand you define the datasource in tomcat, which parameters do you use there?
