Hei Lema, Can You Tell Me Why Are You Using RemoteServiceServlet?

[lema]

Hei Lema,
Why Are You Using RemoteService Servlet?

[lema]

i don't have any other servlet, there is only LoginServlet (in my application it is SmsDeliveryServiceImpl).

when i put HttpServlet instead of RemoteServiceServlet it shows errors on
this.getThreadLocalRequest().getSession(true).setAttribute("user", smdUser);

[javarishi]

Lema,
Can you tell me why are you using RemoteService Servlet?

[javarishi]

If you are using google webtool kit, then it works differently

[lema]

actually.. i think it is for getting methods work in server side. like this for eaxple:

public void checkLogin(String u, String p) throws Exception {
LoginRemote loginRemote =(LoginRemote)
findObject("example.server/login/remote");


SmdUser smdUser = loginRemote.checkLogin(u, p);
if (smdUser != null) {
this.getThreadLocalRequest().getSession(true).setA ttribute("user", smdUser);
RequestDispatcher dispatcher =
getServletContext().getRequestDispatcher("http://111.111.11.111/example/Application.html");
dispatcher.forward(getThreadLocalRequest(), getThreadLocalResponse());

} else {
Window.alert("You are not SMD member!");
}
}

[lema]

oh ya, i use gwt, but for application page. logi page is of jsp

[javarishi]

Yaah, Exactly. Now Lets Look forward for the solution.

[lema]

helloooo? ..but.. the applicatin still doesn work..

you see, first problem appeared when i managed opening the application page ina different window - session lost data (String username. i need it, so that application can show different info for different users working at the same time)

[javarishi]

I am unable to understand. Can you brief me?

[lema]

mean, there are several groups of users. so one group uses info a, second group info b..etc.

then i decided to get approval from servlet into jsp page to decide if to open the application page (but on the same browser) or not to

[javarishi]

Now application Is Running right?

[lema]

look,
1 - opens login page
2 - sends username&password to servlet
3 - servlet checks if the user (username&password) is authorised for using the application
4 - session saves username (to find the user's group, so to decide which info to show on the main Applicatin page)

[lema]

no, doesn't.
actually i wanted to get an approval to jsp page (true or false boolean) from servlet right back after checking the user's authorization.

[javarishi]

Ok Got It, go ahead.

[javarishi]

no, doesn't.
actually i wanted to get an approval to jsp page (true or false boolean) from servlet right back after checking the user's authorization.


Please Explain the above

[lema]

is it possible?.. to get boolean b from servlet after the check. for ex, like this:

<button name="enter" value="Enter SMD" onClick="location.href='http://localhost"8080/example/Applicatio.html'"></button>

[lema]

or <button name="enter" value="Enter SMD" onClick="location.href=(b)?'http://localhost:8080/example/Applicatio.html':'http://localhost:8080/example/smderror.jsp'"></button>
