[jira] Assigned: (XMLRPC-89) cannot use Vector, Hashtable, etc as
arguments of metheds in handler
[ http://issues.apache.org/jira/browse/XMLRPC-89?page=all ]
Jochen Wiedmann reassigned XMLRPC-89:
-------------------------------------
Assign To: Jochen Wiedmann
Preliminary inspection: This is a serious bug, because it will be a problem for backwards compatibility. We can handle it for parameters by automatically converting them. A possible solution for the return value might be to make the type of return value for arrays configurable.
A workaround is to use object arrays, rather than lists, or vectors. In other words, change the client code to
Object[] value = new Object[]{new Integer(0), "abc"};
Object[] parms = new Object[]{value};
Object[] result = (Object[]) client.execute(methodName, parms);
and the server methods signature to
public Object[] methodName(Object[] values) {
...
}
A fix should be available within the next days. I'll defer 3.0b1 until that.
