I build a simple contact manager app with simple service and it did work. Then I decided I want to use Guice for managing my services and implementations. I also use mvp4g plugin for MVP design pattern. I followed the exmaple of Eric Burke on his blog, and my code looks like that:
ContactService.java@RemoteServiceRelativePath("GWT.rpc")
public interface ContactService extends RemoteService {
public void saveContact(Contact c);
public List<Contact> listContacts();
}
ContactServletModule.java:
@Singleton
public class ContactServletModule extends ServletModule{
private static String SQL_MAP_CONFIG = "org/yuri/SqlMapConfig.xml";
private SqlSessionFactory factory = null;
@Provides
public SqlSessionFactory getSqlSessionFactory(){
if(this.factory == null){
try {
/*
* Create new factory
*/
Reader r = Resources.getResourceAsReader(SQL_MAP_CONFIG);
this.factory = new SqlSessionFactoryBuilder().build(r);
} catch (IOException ex) {
/*
* do nothing, factory is null still
*/
} finally{
return this.factory;
}
}
else{
return this.factory;
}
}
@Override
protected void configureServlets() {
serve开发者_运维技巧("/YuriContactManager/GWT.rpc").with(GuiceRemoteServiceServlet.class);
bind(ContactService.class).to(ContactServiceImpl.class);
}
}
MyGuiceContextListener.java
public class MyGuiceContextListener extends GuiceServletContextListener {
@Override
protected Injector getInjector() {
return Guice.createInjector(new ContactServletModule());
}
}
But when when I start my app and try to list contacts by calling listContacts(), tomcat tells me that GWT RPC can't be found (exactly: The requested resource (/YuriContactManager/org.yuri.ContactManager/GWT.rpc) is not available.) My web.xml looks like that:
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

</listener>
<welcome-file-list>
<welcome-file>welcomeGWT.html</welcome-file>
</welcome-file-list>
</web-app>
Any one had similar problem or has any idea what might be wrong?
found the error :) In ContactServletModule serve path needs to be modified to "/org.yuri.YuriContactManager/GWT.rpc"
- I think the reason why is that I'm also using mvp4g framework, but I'm not sure.
