Hi Dirk, Apparently the com.metaparadigm.jsonrpc code is no longer current, replaced by a newly-named JAbsorb package, available from Google Code:
http://code.google.com/p/jabsorb/ This looks to be written by the same author and represents a package name change and some minor changes. In looking into the hooks in JSPWiki it seems that the only requirement would be to alter the servlet package name in web.xml and change the imports in the JSONRPCManager from: import com.metaparadigm.jsonrpc.InvocationCallback; (API) import com.metaparadigm.jsonrpc.JSONRPCBridge; to import org.jabsorb.callback.InvocationCallback; import org.jabsorb.JSONRPCBridge; I've not been able to determine if the bridge has changed in any significant way from the JavaScript side of things, but ostensibily the method calls used seem the same, though the new implementation is missing the setDebug() method. registerCallback() and registerObject() are the same. I was just wondering if you already knew about this change and/or if you knew of any plans to update to this new package. Thanks, Ichiro [PS. and BTW, despite quite a bit of digging into the JSON RPC code, including a fair bit of debugging, I've not yet been able to successfully register a non JSPWiki object and get the bridge to respond with anything except a {"id":10000,"error":{"code":591,"msg":"method not found (session may have timed out)"}} But I keep digging... didn't think this would be so difficult...]
