I wonder if someone has encountered this performance problem in using Castor in a J2EE container.
Castor 0.9.4.3: unmarshalling a large message (> 200 tags) using mapping files. Everything runs pretty fine in a standalone test app (main()) and performance is reasonable (66 ms) per call. After it is moved to a J2EE environment (WebSphere), the same method takes well over 500 ms. 8 times slower. I stepped through the Castor code and found that it is doing a lot of Class.forName() in ClassDescriptorResolverImpl.loadClass(). In my case, I only map a few tags in my mapping file (I only need a small part of the XML file) and Castor is trying to guess and load non-existing java classes (2 calls to Class.forName() for each tag). In J2EE containers, classloading is much slower and it resulted in a bad performance problem for me. Even if I create my own class resolver and setIntrospection(false), it is still doing these Class.forName(). Any ideas of working around this? Or may I suggest to add some code in ClassDescriptorResolverImpl.loadClass(), so that it won't do these Class.forName() when _useIntrospection is false? Or in general, is there a way to disable "Default Introspection" completely? Billy Lo. ===== __________________________________ Do you Yahoo!? SBC Yahoo!
