-------------------------------------

             Summary: bug org.apache.xmlrpc.common.TypeConverterFactoryImpl.java 
                 Key: XMLRPC-192
                 URL: https://issues.apache.org/jira/browse/XMLRPC-192
             Project: XML-RPC
          Issue Type: Bug
          Components: Source
    Affects Versions: 3.1.4
         Environment: Windows 7
            Reporter: Dang Quoc Hien


I found a bug in the code of TypeConverterFactoryImpl.java when trying to create a method
at server side, which accepts parameter with type Object ( public void myMethod(Object o)).
that means myMethod should accept any type of parameter.But the server will procedure an exception
everytime the client call this method with Boolean paramenter. 

SEVERE: No method matching arguments: java.lang.Boolean
org.apache.xmlrpc.XmlRpcException: No method matching arguments: java.lang.String, java.lang.String,
java.lang.String, java.lang.Boolean
	at org.apache.xmlrpc.server.ReflectiveXmlRpcHandler.execute(ReflectiveXmlRpcHandler.java:110)
	at org.apache.xmlrpc.server.XmlRpcServerWorker.execute(XmlRpcServerWorker.java:46)
	at org.apache.xmlrpc.server.XmlRpcServer.execute(XmlRpcServer.java:86)
	at org.apache.xmlrpc.server.XmlRpcStreamServer.execute(XmlRpcStreamServer.java:200)
	at org.apache.xmlrpc.webserver.Connection.run(Connection.java:208)
	at org.apache.xmlrpc.util.ThreadPool$Poolable$1.run(ThreadPool.java:68)
I also found where the problem is, and how to handle it:

In the function public TypeConverter getTypeConverter(Class pClass):
All the if-conditions like  pClass.isAssignableFrom(xxx.class) should be used the otherway
around : if(xxx.class.isAssignableFrom(pClass))...
and also a TypeConverter for Object.class should be added to this class
I have fixed this problem with my own implementation for TypeConverterFactoryImpl. if you
want, I could provide the code.

best regards
