jsp exception shuts down jboss
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:
<%
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?
