Session/user management approach for multiple servlets in GWT/GAE app

[Alex Dobjanschi]

Hi,

I've been unsuccessful in sharing a piece of data (Account) between multiple servlets (doing custom user management, not using UserService).

I'm developing a GWT/GAE app, where multiple client services get implemented by different servlets. What's the best/good approach for this?

Upon login/create account, the serializable Account is stored in one attribute of getThreadLocalRequest().getSession(). I can successfully read that data using the same servlet (AccountServlet), but any other servlet can't ... anything I'm doing wrong? I can also work with any pattern, if supplied :)

Thanks,

Alex

I'm assuming this is on production not dev? Do you have  <sessions-enabled>true</sessions-enabled> in your appengine-web.xml? Are you seeing the sessions persisted to the datastore in _ah_Session?

Sorry for the late response, but I got it working somehow (actually I understood how, but I'm not happy with the current implementation).

Basically what I have is an AccountServlet that performs the login (checks email/passwd combo etc). After validation, the Account is stored in servlet session. The original question was, how to approach user management for multiple servlets?

In a secondary servlet, I need the authentified user. Even more, I define a RemoteService that gets implemented in both the servlet and a delegate (much more useful for junit testing). How should I efficiently work with the Account in the implementation?

interface ISearchService {

 Object doSearch (String query);

}

SearchServlet {

 ISearchService impl = new SearchServiceImpl (); // parameterless constructor (DI).

 public Object doSearch (String query) {

   return impl.doSearch (query);

 }

}

Assume the SearchServiceImpl requires the authentified account. I can successfully fetch it in Servlet. How do I serve it to the impl?

Thanks
