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). Here is the result (pasted from Ethereal, reformatted for readability):
<?xml version="1.0" encoding="UTF-8"?>
<methodResponse>
<params>
<param><value><array><data>
<value><struct>
<member>
<name>version</name>
<value><int>2</int></value>
</member>
<member>
<name>name</name>
<value>UsingTomcatAtAidWorld</value>
</member>
<member>
<name>size</name>
<value>
<?xml version="1.0" encoding="UTF-8"?>
<methodResponse>
<fault><value><struct>
<member>
<name>faultString</name>
<value>java.lang.RuntimeException: unsupported Java type: class
java.lang.Long</value>
</member>
<member>
<name>faultCode</name>
<value><int>0</int></value>
</member>
</struct></value></fault>
</methodResponse>
This is malformed XML, and the client understandably takes a dim view of it:

By the way, is this project dead? There are outstanding issues over 3 years old.
