[ http://issues.apache.org/jira/browse/XMLRPC-71?page=comments#action_12361422 ]
Jochen Wiedmann commented on XMLRPC-71: --------------------------------------- I was looking through the sources today, and I could not think of a way how this problem might arise. Here's what I do see: - The XmlRpcResponseProcessor's encodeResponse method is called. It fails, because of the invalid object in the Hashmap. An exception is being thrown. - Nothing is written to the output stream yet. - The exception is catched in the XmlRpcWorker's execute method. The XmlRpcResponseProcessor's encodeException is called. This should work fine and the error message is being written. > Trying to serialise an unserialisable class breaks XML format spec > ------------------------------------------------------------------ > > Key: XMLRPC-71 > URL: http://issues.apache.org/jira/browse/XMLRPC-71 > Project: XML-RPC > Type: Bug > Components: Source > Versions: 2.0 > Environment: Linux (FC2 server, Suse 9.1 client), Java 1.4 on server, 1.5 on > client, Tomcat 4.1 on server > Reporter: Chris Wilson > > I tried to make a method return a vector containing a Hashtable containing a > Long, and invoke that method via XML-RPC (Apache XML-RPC on both client and > server).
