Hibernate version:3.3.1.GA

I'm using Tomcat 6.

I can compile my classes fine, but when I try to run the webapp, I get:

Code:
HTTP Status 500 -

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

Here's my classpath:
Code:
me@mycomputer:~$ echo $CLASSPATH
.:/home/me/tomcat6/lib/servlet-api.jar:/home/me/tomcat6/lib/jsp-api.jar:/home/me/tomcat6/webapps:/home/me/tomcat6/lib/mysql-connector-java-5.1.6.jar:/home/me/tomcat6/lib/hibernate3.jar:


I was able to test my classes before dumping them into Tomcat and they persisted my test objects into MySQL perfectly fine. I can't figure out why Tomcat can't find Hibernate. I don't see any spelling errors or missing colons or anything!

Hi Everyone

I found no replies to this topic and related topics of this..Why i donno ?? :(

http://forum.hibernate.org/viewtopic.php?t=994782


Please tell me how can i integrate hibernate with tomcat !!

Main problem i am facing is starting session from tomcat..
Please see the above post..I am searching in net and not getting
right guidelines to start it..

May i know how can i start my hibernate session from aar file which is deployed rather than doing it from outside aar file [like copying my configuration files of hibernate into web-inf/classes and all hibernate libs to webinf\lib ..I tried this tooo but not working ??

So hoping for replies this time...

You can also put the library in your tomcat lib ($CATALINA_HOME/common/lib), but this way is not recommended. It can cause conflict if this lib exists in other project with different version

Hi anudeep,

I don't have any experience with axis. So I don't know how to set up aar files.

But have you tried simple web app in tomcat. For a simple web app or war to work, you just need the hibernate and dependent libs in WEB-INF\lib folder of your war. Have you tried this? If so plz post the contents of your WEB-INF\lib dir.
