Hi Everyone,
I hope I am able to get an answer to this.
I am trying to tie a backend servlet process to a GWT servlet.
How do I map this to work properly
I am using Jetty 6
GWT 2.01
Eclipse Ganymeade
Here is the code
========================================================================================
package com.co.SSIS.server;
import com.co.SSISSERVER.users.User;
import com.co.SSISSERVER.users.UserService;
import com.co.SSISSERVER.users.UserServiceImpl;
import com.co.SSIS.client.LoginInfo;
import com.co.SSIS.client.LoginService;
import com.google.gwt.user.client.rpc.RemoteServiceRelativePath;
import com.google.gwt.user.server.rpc.RemoteServiceServlet;
@RemoteServiceRelativePath("/ssisajaxserver/User")
public class LoginServiceImpl extends RemoteServiceServlet implements
LoginService {
public LoginInfo login(String loginURL) {
UserService userService = UserServiceImpl.getUserService();
User user = userService.getCurrentUser();
LoginInfo loginInfo = new LoginInfo();
if (user != null) {
loginInfo.setLoggedIn(true);
loginInfo.setUserName(user.getUserName());
loginInfo.setAuthority(user.getAuthority());
loginInfo.setBuilding(user.getBuilding());
loginInfo.setTeacher(user.getTeacher());
} else {
loginInfo.setLoggedIn(false);
}
return loginInfo;
}
}
Here is the web.xml for the backend
=========================================================================================
<web-app>
<display-name>SSISJAXSERVER</display-name>
<description>SSIS Version 6 Web Appliction</description>
<!-- Servlets SSIS Processing -->
<servlet>
<servlet-name>SSISAJAXSERVER</servlet-name>
<servlet-class>com.co.SSISSERVER.server.SSISProducer</servlet-
class>
</servlet>
<servlet>
<servlet-name>UserServiceImpl</servlet-name>
<servlet-class>com.co.SSISSERVER.users.UserServiceImpl</servlet-
class>
</servlet>
<!-- SSISProducer for SSIS Processing -->
<servlet-mapping>
<servlet-name>SSISAJAXSERVER</servlet-name>
<url-pattern>/login.html</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>UserServiceImpl</servlet-name>
<url-pattern>/User</url-pattern>
</servlet-mapping>
Here is the servlet path
========================================================================================
/ssisajaxserver/User
Here the servlet path is answering to a get which of course does not
work
=======================================================================================
HTTP ERROR: 405
HTTP method GET is not supported by this URL
RequestURI=/ssisajaxserver/User
Here is gwt.xml
========================================================================================
<?xml version="1.0" encoding="UTF-8"?>
<module rename-to='ssisajax'>
<!-- Inherit the core Web Toolkit stuff. -->
<inherits name='com.google.gwt.user.User'/>
<!-- Inherit the default GWT style sheet. You can change -->
<!-- the theme of your GWT application by uncommenting -->
<!-- any one of the following lines. -->
<inherits name='com.google.gwt.user.theme.standard.Standard'/>
<!-- <inherits name='com.google.gwt.user.theme.chrome.Chrome'/> -->
<!-- <inherits name='com.google.gwt.user.theme.dark.Dark'/> -->
<!-- Other module inherits -->
<!-- Specify the app entry point class. -->
<entry-point class='com.co.SSIS.client.SSISAJAX'/>
<!-- Specify the paths for translatable code -->
<source path='client'/>
<source path='shared'/>
<servlet path='/ssisserver/User' class='com.co.SSISSERVER/users/
UserServiceImpl'/>
</module>
Here is the Stack Trace
