"org.hibernate.Session" ClassNotFoundException

Hello to all,

Despite I added all necessary .jar files to project, I always take boring exception warnings that say "class not found". I added the code and exception output below. I'll be so happy if someone can help me.

Thanx in advance..
With regards,
T

public JSONArray getAll() {

If that was true, you wouldn't get that error...

You need the Hibernate jar on your classpath (e.g. hibernate3.jar or hibernate-3xxx.jar).

Doing more things faster is no substitute for doing the right things...

Here's the link for my small test project. I'll be happy if you can try it on your computer.
Thanks in advance..
~~EDIT~~

No thanks.

Did adding the hibernate jar to your classpath work?

The value of a prototype is in the education it gives you, not in the code itself...

I just added all my external jar files into my server's (Apache Tomcat 6.0) "lib" folder. Eventually, this exception has gone.. But unfortunately now I take another exception: java.lang.ClassNotFoundException: org.apache.commons.lang.exception.NestableRuntimeException" I googled this expection and I added commons-lang-2.5.jar into my lib. Despite that it still gives exception..

I can only repeat that if the correct jar is on the classpath, you won't get the exception. Are you certain a jar containing the relevant class is on the server classpath (e.g. WEB-INF/lib/)?

Was it something I said (repeated) ?

If Java had true garbage collection, most programs would delete themselves upon execution...

yes, exactly. It was occured because of 'build path' mistake..
Thanks you so much again.

Wish I'd mentioned it...
