Automatic reloading of recompiled portlets?
Is automatic reloading of portlets implemented in jetspeed 1.3a1?
After recompiling a portlet und accessing it, I get following error message:

The problem comes if you change the whole jar, and turbine reloads. I'm not completely sure,
but I think it is due that the object stored in the Request is an "new" org.apache.turbine.util.RunData,
while you are casting it to a "old" org.apache.turbine.util.RunData, as jsp are not recompiled. It this
is the explanation, then it qualifies as a tomcat bug. Tomcat should force recompilation of all jsp classes
belonging to a context whenever any context jar is reloaded.
Two java classes are the same if they have the same qualified name AND the same classloader. When you change
the jar, tomcat creates a new classloader to reload turbine. So, the cast fails, as the jsp file is compiled
and loaded against the "old" jar.
I'm not sure on how to handle this.
