HI
I m new to GWT i would like to know how to HttpSession in the RemoteService
interface
I used solve the RPC services using GwtRpcController.java class
and used get the session
HttpSession httpSession = getThreadLocalRequest().getSession();
but it is run smmothely in GWT Hosted mode but when deployed in the Jboss it
getting null pointer exception
below i mentioned the controller class
import javax.servlet.ServletContext;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.context.ServletContextAware;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;
import com.google.gwt.user.client.rpc.IncompatibleRemoteServiceException;
import com.google.gwt.user.client.rpc.RemoteService;
import com.google.gwt.user.client.rpc.SerializationException;
import com.google.gwt.user.server.rpc.RPC;
import com.google.gwt.user.server.rpc.RPCRequest;
import com.google.gwt.user.server.rpc.RemoteServiceServlet;
public class GwtRpcController extends RemoteServiceServlet implements
Controller, ServletContextAware {
private ServletContext servletContext;
private RemoteService remoteService;
private HttpServletRequest httpServletRequest;
private HttpServletResponse httpServletResponse;
private Class remoteServiceClass;
public ModelAndView handleRequest(HttpServletRequest request,
HttpServletResponse response) throws Exception {
super.doPost(request, response);
httpServletRequest = request;
httpServletResponse = response;
return null;
}
@Override
public String processCall(String payload) throws SerializationException
{
try {
RPCRequest rpcRequest = RPC.decodeRequest(payload,
this.remoteServiceClass);
// delegate work to the spring injected service
return RPC.invokeAndEncodeResponse(this.remoteService,
rpcRequest
.getMethod(), rpcRequest.getParameters());
} catch (IncompatibleRemoteServiceException ex) {
getServletContext()
.log(
"An IncompatibleRemoteServiceException was
thrown while processing this call.",
ex);
return RPC.encodeResponseForFailure(null, ex);
}
}
public HttpServletRequest getHttpServletRequest() {
return httpServletRequest;
}
public void setHttpServletRequest(HttpServletRequest httpServletRequest)
{
this.httpServletRequest = httpServletRequest;
}
public HttpServletResponse getHttpServletResponse() {
return httpServletResponse;
}
public void setHttpServletResponse(HttpServletResponse
httpServletResponse) {
this.httpServletResponse = httpServletResponse;
}
@Override
public ServletContext getServletContext() {
return servletContext;
}
public void setServletContext(ServletContext servletContext) {
this.servletContext = servletContext;
}
public void setRemoteService(RemoteService remoteService) {
this.remoteService = remoteService;
this.remoteServiceClass = this.remoteService.getClass();
}
}
