Re: Way to reload struts Action classes in WebLogic8.1

[Michael McGrady]

Isn't the trick to load the classes with a classloader that does not 
require you to reload the entire webapp?  This is a combination question 
and statement.  I am interested in this issue and want to find a way to 
load classes in a webapp which will be workable.  I am thinking of the 
stuff that has been discussed in books on container programming in Java.

Hello,
Is there a way to reload Actions in Weblogic without redeploying the web

No.  Java provides no way to replace a class (loaded by a particular class 
loader) with a modified version, without throwing away the entire class 
loader.  That's what normally happens when you reload a webapp.

I have the servlet reloading enabled , but weblogic doesnt seem to recognize
the changes to the Action classes and throws a ClassCastException.
So every small change I make, I have to redeploy the Web app which makes the
whole development process slow.
I don't know about Weblogic, but Sun's app servers (and Tomcat) have 
"reload" options that are *much* faster than the undeploy/redeploy cycle 
it sounds like you are using.  Check the docs.
