Spring Security relogin Transport Error - HTTP code 500

[liudi]

Hi,

i followed the Spring Security relogin thread http://forums.smartclient.com/showthread.php?t=9633

this is a great sample that meets almost all my needs. The original sample uses In-Memory authentication, it works well. After then i tried to enable DAO authentication in our project, i got Transport error - HTTP code: 500 for URL: /BuiltInDS/j_spring_security_check error when i click on the Login button of the LoginWindow.

Here's what i modified based on the original code:

in the applicationContext-security.xml i used a customized UserDetailService to perform the authentication

    <security:authentication-manager alias="authenticationManager">
        <!--<security:authentication-provider>
            <security:user-service>
                <security:user name="test" authorities="ROLE_USER" password="test"/>
            </security:user-service>
            </security:authentication-provider>-->
        
        <authentication-provider user-service-ref = "userDetailsService">
            <password-encoder hash="md5"/>
        </authentication-provider>
    </security:authentication-manager>

    <beans:bean id = "userDetailsService" class = "com.smartgwt.sample.server.service.MyUserService" />

And then i override the loadUserByUsername function of the UserDetailsService:

public class MyUserService implements UserDetailsService{

	@Override
	public UserDetails loadUserByUsername(String username)
			throws UsernameNotFoundException, DataAccessException {
		
		try{
			/** retrieve user using iBatis + Spring **/
			TransactUserExample exa = new TransactUserExample();
			exa.createCriteria().andUsernameEqualTo(username);
			
			List<TransactUser> users = TransactInitServlet.getUserDAO().selectByExample(exa);
			
			if(users.size() == 1) {
				TransactUser u = users.get(0);
				GrantedAuthorityImpl auth = new GrantedAuthorityImpl(u.getRole());
				User user = new User(u.getUsername(), 
						u.getPassword(), true, true, true, true, getAuthorities(u.getRole()));
				
				return user;
			}
		} catch(Exception ex) {
			ex.printStackTrace();
		}
		return null;
	}
	
	private GrantedAuthority[] getAuthorities(String role) {
        List<GrantedAuthority> authList = new ArrayList<GrantedAuthority>(2);
        authList.add(new GrantedAuthorityImpl(role));
        return authList.toArray(new GrantedAuthority[] {});
    }

}

Before putting these changes to my SmartGwt project, i tried it in a simple web application with only 2 JSP pages, it worked, but got problem now.

After a bit of research and looking at the server logs, the method loadUserByUsername gets called, but it looks like that no response has been returned to the client side (or null DSResponse?), did i miss anything? is this the proper way of doing the authentication using Spring Security?

Thanks!

sorry, this might be my problem, just sawan exception from RPC tab, i might have missing .jar files in my class path.

Problem solved, it's working now. it was because the some missing jar files and Spring-2.0.jar has a version problem.
