Thread: glassfish ClassNotFoundException java.lang.ClassNotFoundException: ...

hi,

my eclipse is:
-------------------------------------------------------
Eclipse Java EE IDE for Web Developers.

Version: Indigo Service Release 2
Build id: 20120216-1857

--------------------------------------------------------
Glassfish 3.1.2
mysql-connector-java-5.1.18-bin.jar
--------------------------------------------------------

I wrote my own DAL.
I exported it as a jar file and added another java project.
Everything is ok and it works perfect. It can connect to mysql and gets data.

Now, I tried to write a simple dynamic web project (jsf) and published to glassfish.
When I called the start page, it gives me an error like tihs:

ClassNotFoundException java.lang.ClassNotFoundException: DAL.SqlClient.SqlKullTipProvider

I'm using this code for getting instance of classes.

_instance = (KullTipProvider)Class.forName("DAL.SqlClient.SqlKullTipProvider", true, ClassLoader.getSystemClassLoader()).newInstance();

Thanx...

server log is:
