Method Detail

resolveDispatchTarget

protected abstract Object resolveDispatchTarget(String servletContextPath)

Resolve the target impl that ultimately handles the GWT RPC request, provided a key.

Parameters:

servletContextPath - the portion of the http request path beyond the servlet context, used to uniquely identify the target impl

Returns:

the object that handles the request

Throws:

GwtRpcProxyException - if no target can be found

doUnexpectedFailure

protected void doUnexpectedFailure(Throwable e)

Overrides:

doUnexpectedFailure in class com.google.gwt.user.server.rpc.AbstractRemoteServiceServlet

getDispatchKey

protected String getDispatchKey()

Returns the dispatch key for this request. This name is the part of the request path beyond the servlet base path. I.e. if the GwtRpcPluginProxyServlet is mapped to the "/gwtrpc" context in web.xml, then this method will return "testservice" upon a request to "http://localhost:8080/pentaho/gwtrpc/testservice".

Returns:

the part of the request url used to dispatch the request

getServletContextPath

protected String getServletContextPath()

processCall

public String processCall(String payload)
                   throws com.google.gwt.user.client.rpc.SerializationException

Overrides:

processCall in class com.google.gwt.user.server.rpc.RemoteServiceServlet

Throws:

com.google.gwt.user.client.rpc.SerializationException
