Title: RE: Class Loaders and axis

Do you have any examples of ClassUtils usage.   sagar   -----Original Message----- From: Sagar Pidaparthi Sent: Thursday, July 29, 2004 4:51 PM To: [EMAIL PROTECTED] Subject: RE: Class Loaders and axis   Thanks for your message.  After reading the APIs in this class, I come to the conclusion that I need to do the following.  Please comment if this is right.   1.  Write  myjava2wsdl tool in which I first set the class loader to be myClassLoader, using setClassLoader Method. 2.  Then call java2wsdl program which will convert a java program to wsdl 3.  Similarly for wsdl2java follow the steps described above. Is this right? Secondly how do objects get instantiated during the run time. I am sure that there is a better mechanism then the one I described above.  If there is a configuration file that can be used to specify a class loader and a bunch of classes that need to be picked up by Axis, it should work with minimal work. I would appreciate your answer.  Is there an example of the usage of this class.

In the past we had a factory that used to vend the right MyService. However, with Axis we need to ensure that this trick of loading the CustomServiceClass should now be done inside a class loader that vends the right class, when ever MyService is requested using a default constructor. Question: I have two options, one to instantiate the class loader in the initialization and inspect each class and see if it needs to be loaded with customized classes. Or Use the class loader when ever Axis makes a call to load the classes. Does axis give me a mechanism to use the class loader whenever it tries to load classes to generate WSDLs or service the requests etc. i.e for all Axis work, I wish to use my class loader and not disturb any of my existing (mammoth) legacy application.   I would appreciate your help.
