invokeHandler

protected static java.lang.Object invokeHandler(java.lang.Object handler,
                                                XmlRpcServerRequest request,
                                                XmlRpcContext context)
                                         throws java.lang.Exception

public byte[] execute(java.io.InputStream is,
                      java.lang.String user,
                      java.lang.String password)

Decode, process and encode the response or exception for an XML-RPC request. This method executes the handler method with the default context.

execute

public byte[] execute(java.io.InputStream is,
                      XmlRpcContext context)

Parameters:

is - the InputStream to read the request from.

context - the context for the request (may be null).

Returns:

byte[] the response.

Throws:

ParseFailed - if the request could not be parsed.

AuthenticationFailed - if the handler for the specific method required authentication and insufficient credentials were supplied.

                                       java.lang.String password)

Factory method to return a default context object for the execute() method. This method can be overridden to return a custom sub-class of XmlRpcContext.

Parameters:
