Sometimes ClassNotFoundException [SOLVED]

["Dirschnabel. Stefan" <s....@seeburger.de>]

Ok, I found the mistake at last. Problems were wrong servlet mappings (to not existing pre compiled jsp's) in the web.xml because of a mistake in the build script. Big thx for all help

No .... it would be very reproduceable if the jsp isn't compiling for 
some reason.  I've seen this error when importing jsps that don't 
compile/aren't found using the <c:import url="/InventoryStatus.jsp" /> 
tag.  Can you verify that InventoryStatus.jsp is in the webapp or 
optionally if using precompiled jsps that the Inventory_jsp.class is 
available in the webapp?
