Pls Help - ClassNotFoundException error - custom activity space and control

Question

I am encoutnering the following error when I deploy and run my custom
Login Activity Space and Control to the Java 5.0.2 Portal. I have created a custom Java project and built successfully(I think) using Ant and have modified the customactivityspaces.xml file appropriately. I have checked that the custom jar file is in the portal.war and PORTAL_HOME\lib\java\ folder. Any help with this would be extremely appreciated.
Please let me know if I can provide more info.
Thanks.

Answer 1

Thanks a lot for your help Julie! That worked.
I have a followup question. Now, I get the Login view even though I didn't include a login view in my custom activity space.
I am trying to develop the custom login activity space and don't want to display the default loginview and want to auto login. So I have created a custom activity space and a custom control. I am not sure if I have everything coded correctly yet. How do I make sure I don't display the login view if I go to my custom space directly?
What's the best way to do this? I am still trying to go through the PT code and understand it. Any pointers would be very helpful.
Additionally, for the custom activity space: do I need to extend PlumtreeAS or AActivitySpace ?
I have my code listed below:
