I'm using GWT and GAE for my project. I'm using data transfer objects and dozer to move data between client and server. Dozer had been working great, but I have some classes that need to store text that is over 500 characters, so I must use com.google.appengine.api.datastore.Text datatype in my server side object, but a regular String in my client side object. How do I map these two types using dozer? I know somehow I can specify an XML file, but how do I write that XML file?
