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 -----Original Message----- From: Nicholas Hemley [mailto:nic.hem...@sidonis.com] Sent: 05 January 2010 11:07 To: xmlrpc-dev@ws.apache.org 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
