    Default 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:

    Have you included your DAL classes in your web application archive (war) under the WEB-INF/classes or if it was packed as jar file under the WEB-INF/lib?
