Re: One Session(HTTP) for multiple GWT-Modules?
And how can i track the session id? I can store the sessionId at the client-side (for users which have cookies disabled), but if they reload the client-side the sessionId will be lost. So, what do you think: Will it be a "good solution" to add the sessionId into the URL to enable session tracking for users without cookies enabled? Or is there another way?

Cookies are fine, but what happens if cookies are disabled? Then two sessions will be created by the server, or not?

Re: One Session(HTTP) for multiple GWT-Modules?
But if i have two seperate modules each client will get a different sessionId from the server (rpc-call), because the servers interprets each module as a single client!?

Re: One Session(HTTP) for multiple GWT-Modules?
Yes, thats right. But will it then be possible to make in each module a gwt-rpc-call which checks, if the user is logged-in?

One Session(HTTP) for multiple GWT-Modules?
hello, im implementing a little online-game with gwt. this game contains two modules - one ui for the game itself and a seperate user-area. if a user is logged-in into the user-area he should be able to write comments etc. in the game-gui (the other module). is it possible to share a http-session between the modules? what could be a solution? thanks for any help! johannes -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

GWT Session Handling - user HTTP Session or own solution?
Hello, im thinking about how to handle user-sessions. As i can remember there is the possibility to use HTTPSession (Servlet). Is this recommendable? Or is it a better idea to use an own solution?

For each request the session will be send to the server (rpc-call). Thats my auth-process.

Hey, i deployed a gwt-application in tomcat 6.0.18 without any problems.

Connecting GWT-Modules / Rewrite URL
hello, i am developing a little online-game with gwt. the application contains several little modules. these modules are embedded in some html files. we have one html file for a latest-news-module, one for a category-listing and for the game itself. currently we access each module by url, for ex. http://myurl/start.html , http://myurl/quiz.html and http://myurl/category.html. in case that we have a lot of games and a lot of categories we use the anchor of an url (history) for delivering parametes, for ex. http://myurl/quiz.html#playid:200. but this is not really search-engine friendly, because they ignore this. what do you recommend? is it recommendable to use instead a construct like http://myurl/quiz.html?id=id and then to rewrite the url by URLRewriteFilter (http://urlrewritefilter.googlecode.com/svn/ trunk/src/doc/manual/3.2/guide.html) and is it even recommandable to navigate like me through the modules? or is there another, much more elegant way? sorry for my english. i hope i did not make too much mistakes. johannes -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Serialization Error with own class while compiling
Hey folks,
thank you for your help.
I got it fixed. I missed to implement a zero-argument constructor in
Kontakt...
Damn... im so blind! But sometimes you need to have a night to rethink
on it again.
Okay, but there´s one new question.
In my database (dont know why it was designed this way) the date is
splitted into three integer-columns: day, month, year.
Okay, for my comparison i need to transform this into a Date-Object.
But this does not work, if im using the DateTimeFormat-Class of GWT.
It uses GWT.Create() in his code, what´s prohibeted on server-side
code, so that this error occurs:
Caused by: java.lang.UnsupportedOperationException: ERROR:
GWT.create() is only usable in client code! It cannot be called, for
example, from server code. If you are running a unit test, check that
your test case extends GWTTestCase and that GWT.create() is not called
from within an initializer or constructor.[...]
I use this Domain-Construtor for this:
public Domain(String adresse, String tld, int tag, int monat, int
jahr, Kontakt kontakt) {
DateTimeFormat fmt = DateTimeFormat.getFormat("dd.MM.yyy");
this.setRegistrar(new Kontakt("Keine Angabe"));
this.adresse=adresse;
this.tld=tld;
this.owner=kontakt;
this.next=fmt.parse((tag+"."+monat+"."+jahr));
return;
}
Do you may have an idea, how it could work?
Thank you for your recent help!

p.s.: greetings from germany.I hope my English is not as bad as I
think. :P

Serialization Error with own class while compiling
Hey,
ive got a problem and im searching for hours to find a solution.
My problem is the following:
I have a little RPC-Service which returns as a result a "Domain"-
Object (Own custom-class).
But this Domain-Object could not be serialized, though i have made
this "Domain"-class serializable with
com.google.gwt.user.client.rpc.IsSerializable.
Im using GWT SDK 2.01 and getting the following compiling error:
[ERROR] com.google.gwt.core.client.JavaScriptObject is not assignable
to 'com.google.gwt.user.client.rpc.IsSerializable' or
'java.io.Serializable' nor does it have a custom field serializer
(reached via com.vostokdomains.kis.client.objetcs.Domain)
[ERROR] com.google.gwt.core.client.JavaScriptObject has no available
instantiable subtypes. (reached via
com.vostokdomains.kis.client.objetcs.Domain)
I hope you can help me out!!
Enclosed some code-snippets:
package com.vostokdomains.kis.client.objetcs;
import java.util.Date;
import com.google.gwt.i18n.client.DateTimeFormat;
import com.google.gwt.user.client.rpc.IsSerializable;
== Domain-Object
public class Domain implements Comparable, IsSerializable{
private String adresse;
private String tld;
private Date create;
private Date next;
private int laufzeit;
private double preis;
private Kontakt registrar;
private Kontakt admin;
private Kontakt tech;
private Kontakt owner;
private String namesever1;
private String nameserver2;
private String records;
Domain(){
}
public Domain(String adresse, String tld, int tag, int monat, int
jahr, Kontakt kontakt) {
DateTimeFormat fmt = DateTimeFormat.getFormat("dd.MM.yyy");
this.setRegistrar(new Kontakt("Keine Angabe"));
this.adresse=adresse;
this.tld=tld;
this.owner=kontakt;
this.next=fmt.parse((tag+"."+monat+"."+jahr));
return;
}
public Domain(String adresse, String tld, Kontakt kontakt){
this.setRegistrar(new Kontakt("Keine Angabe"));
this.adresse=adresse;
