Hello,

I have diagnosed this problem and it appears that void methods are turned on
if content extensions are turned on.

FYI the following code in the overridden Servlet is a workaround:

/** Creates a new instance of {@link PropertyHandlerMapping} by
	 * loading the property file from the given URL. Called from
	 * {@link #newXmlRpcHandlerMapping()}.
	 */
	@Override
	protected PropertyHandlerMapping newPropertyHandlerMapping(URL url)
throws IOException, XmlRpcException {
        PropertyHandlerMapping mapping = new PropertyHandlerMapping();
        mapping.setAuthenticationHandler(getAuthenticationHandler());
        if (getRequestProcessorFactoryFactory() != null) {
 
mapping.setRequestProcessorFactoryFactory(getRequestProcessorFactoryFactory(
));
        }
        if (getTypeConverterFactory() != null) {
            mapping.setTypeConverterFactory(getTypeConverterFactory());
        } else {
 
mapping.setTypeConverterFactory(getXmlRpcServletServer().getTypeConverterFac
tory());
        }
        mapping.setVoidMethodEnabled(false);
        mapping.load(Thread.currentThread().getContextClassLoader(), url);
        return mapping;
	}

Cheerio,
Nic

Subject: problem upgrading from 3.0 to 3.1.2

Hello,

 

I have recently installed the 3.1.2 jars in place of the 3.0 jars and have
encountered a problem.

 

None of my XmlRpcServlets work and when I connect, the following error is
reported:

 

java.lang.IllegalStateException: Invalid parameter or result type:

javax.servlet.ServletRequest

 

org.apache.xmlrpc.common.TypeConverterFactoryImpl.getTypeConverter(TypeConve

rterFactoryImpl.java:296)

 

This error occurs at the beginning of my overridden
newXmlRpcHandlerMapping() method

 

protected XmlRpcHandlerMapping newXmlRpcHandlerMapping() throws
XmlRpcException {

...

here >> PropertyHandlerMapping mapping = (PropertyHandlerMapping)
super.newXmlRpcHandlerMapping();

...

}

 

Please can anyone explain this problem? Is the XML-RPC documentation on the
website not up to date?

 

Cheerio,

Nic Hemley
