TilesPlugin : factory already exists/no hot deploy

[Nicholas Grabowski <ni...@schwab.com>]

I am trying to "hot deploy" struts action classes, forms, etc. on a
running weblogic server 6.1 (compile the classes and use them without
restarting the server).  However, quite often (although not always) I
get the following error.  It seems that if I've already used the action
in question, and then change the code, recompile it, and test the same
scenario (a request for a page that causes an action to be used) then
the server throws this error.  Is what I'm trying to do even possible
with struts/tiles?  Or does it require a restart before it can use
changed class files?  Could this be a classloader issue?  THat would be
first guess since I doubt Tiles or struts decides when and if to rreload
a class?  But if this is the case, why is struts throwing the null
pointer exception?  

Thanks
Nick
