Subject Security Manager, Embedded and Class Loading
Date Tue, 04 Sep 2001 17:27:10 GMT
I've a problem that I don't really understand.

I'm in the process of getting the security manager to work with an
Embedded setup and the bootstrap is virtually the same as Catalina's.

If I create, for example, a (Standard)Server and (Standard)Service, I
get objects generated. If I attempt to create an engine, the classloader
(catalinaLoader) finds the (Standard)Engine class, but is unable to
create a newInstance.

ie ...



    /**
     * Create a new server instance.
     */
    public void serverCreate() {
        try {
            Class serverClass =
catalinaClassLoader.loadClass("org.apache.catalina.core.StandardServer");
            Object server = serverClass.newInstance();
        } catch (Exception ex) {
        }
    }

... will create a : org.apache.catalina.core.StandardServer@5d56d5


but a 



    public void engineCreate() {
        try {
            Class engineClass =
catalinaClassLoader.loadClass("org.apache.catalina.core.StandardEngine");
            Object engine = engineClass.newInstance();
        } catch (Exception ex) {
        }
    }


will give a : StandardEngine[null]


..... note that the full package name is missing and that engineClass is
found.


If anybody can shed any light on this, I'd be very grateful for comment
