I downloaded the nightly snapshot from CVS and it seems to be able to handle Maps fine if I use "auto-complete='true'" in my mapping file and let Castor introspect my object.
However, I would like Castor to call my getters and setters. What attributes do I have to set in the Field element of my mapping file to do this? Specifically, what do I put for "type" -- the type of the key or the type of the value? I assume it wants the type of the value, so where do I specify the type of the key? Also, what signatures do the "get-method" and "set-method" expect? I could not find any documentation on this. If it already exists, I apologize for asking these questions -- please let me know where the documentation is instead.

If you can, you should try that version (by using either CVS or a nightly snapshot) and see if it fits your needs. The keys are now output by default. --Keith SUDHIR KULKARNI wrote: > > Hi > I am trying to Marshal java.util.Map by > implementing FieldHandler interface. > Problem: No exception thrown- Map is marshalled with > no keys but only values. > I am using castor 0.9.5.2 and marshalling Map object > on an event in web application which is > running on IBM Websphere.
