The reason is, that most things depend on the client and the HTTP headers, which are received by the client.
There is one very important property to configure, though:. Basic authentication is frequently used to authenticate and authorize users.
The handler receives an instance of XmlRpcRequest. This object has methods getBasicUserName , and getBasicPassword , which provide the necessary details. In other words: Your task is to provide your own instance of XmlRpcHandlerMapping , which creates your own handlers. And your own handlers are responsible to validate the basic authentication details. Here's an example servlet, which overrides the default PropertyHandlerMapping. Why this is the case, can hardly be explained, because the WebServer is at best a workaround, compared to full blown servlet engines like Tomcat or Jetty.
For example, under heavy load it will almost definitely be slower than a real servlet engine, because it does neither support proper keepalive multiple requests per physical connection nor chunked mode in other words, it cannot stream requests. If you still insist in using the WebServer, it is recommended to use its subclass, the ServletWebServer instead, which offers a minimal subset of the servlet API. In other words, you keep yourself the option to migrate to a real servlet engine later.
Use of the WebServer goes roughly like this: First of all, create a property file for example "MyHandlers. The property keys are handler names and the property values are the handler classes. Once that is done, create an instance of WebServer. The Calculator class can be found above.
The Adder and AdderImpl classes can be found in the proxy example. BindException: Permission denied Something went wrong while starting the server : java. BindException: Permission denied at java. BindException: Address already in use java. BindException: Address already in use at java. IOException: Unable to locate resource handler. Make sure that the web.

Code2care is an initiative to publish and share varied knowledge in programming and technical areas gathered during day-to-day learnings and development activities. Let's first look at how to register handler objects to tell an XML-RPC server how to map incoming requests to actual methods.
The org. XmlRpcServer and org. Depending on what kind of handler object you give to the server, it will do one of the following things:. Note that the execute method does not throw any exception, since all errors are encoded into the XML result that will be sent back to the client.
A full example servlet is included in the package. You can use it as a starting point for your own needs.
