Yup, just like the subject said.

Here's what I was trying to do and what happened.

I'm using jboss-4.0.3SP1

I need to configure a security domain to authenticate using a mysql database - this is another beast by itself that I am having some trouble with.

So first I want to make sure I have our datasource setup properly - so as many other examples do - I try to make a servlet to do so.  However, this exception is not datasource related - it occurs before we even try to establish a connection.  

So i wrote a little servlet that contained:

anonymous wrote : <%
  | javax.naming.InitialContext ctxt = new javax.naming.InitialContext();
  | javax.sql.DataSource ds = (javax.sql.DataSource) ctxt.lookup("java:MySqlDS");
  | java.sql.Connection con = ds.getConnection();
  | %>
  | 

I was getting this message with the exception:

javax.servlet.ServletException: Could not create connection; - nested throwable: (org.jboss.resource.JBossResourceException: Failed to register driver for: com.mysql.jdbc.Driver; - nested throwable: (java.lang.ClassNotFoundException: com.mysql.jdbc.Driver)); - nested throwable: (org.jboss.resource.JBossResourceException: Could not create connection; - nested throwable: (org.jboss.resource.JBossResourceException: Failed to register driver for: com.mysql.jdbc.Driver; - nested throwable: (java.lang.ClassNotFoundException: com.mysql.jdbc.Driver)))


so I tried adding:

        try {
            Class.forName("com.mysql.jdbc.Driver").newInstance();
        } catch (ClassNotFoundException cnfe) {
            out.println("Couldn't find the driver!");
            out.println("Let's print a stack trace, and exit.");
            cnfe.printStackTrace();
            System.exit(1);
        } catch(Exception e){
            e.printStackTrace();
        }

before trying to create the initialcontext

This is where the fun starts!

Now, when I try to load the servlet (through tomcat) when Class.forName is called - this happens...

Gotta Love it.  This very well may be because of a classloader issue on my own part - but I assume this is not intended behavior. 

If this is simply one of those dumb classloader issues - where do I need to put the appropriate mysql jar?
