Summary: Dynamic Class Loading issue
Initial Comment:
Problem Description:
----------------
Dynamically generated classes (while running jboss
server) that are placed under C:/classes/ directory
is not visible to the war file which is deployed
under server/default/deploy/ directory.
My Configuration:
--------------
Version: 3.2 RC 2.0 (with bundled Jetty)
Platform: Windows 2000
Jdk: 1.3.1_02
Steps to reproduce:
---------------
1. Create a classes directory under c:/
2. Add the classes directory to the conf/jboss-
service.xml <classpath>
<classpath codebase="file:/C:/classes/" />
3. Start the jboss server in default mode ( run.bat)
4. Put the attached myapp.war file in the
default/deploy directory
5. Copy and Paste the following content in
MyClass.java and compile it and put it under
c:/classes directory.
package com.mycom;
public class MyClass
{
private String data;
public MyClass()
{
data = "foooo";
}
public String getData( )
{
return data;
}
}
6. Try invoking the MyApp war like below
http://localhost:8080/myapp/
7. You will see ClassDefNotFound printStackTrace
on the dos shell.

If you want you can just copy the attached
MyClass.class to your c:/classes directory.
