Re: Trying to use server in another module
I have been making changes to the XML files and now it doesn't work again. I think I left them like they were, but now when trying to debug in a JBoss server I get the following error: java.net.factoryurlclassloa...@4e33e7 x.gwtlogin.server.GwtLoginServiceImpl java.lang.ClassNotFoundException: x.gwtlogin.server.GwtLoginServiceImpl ... This actually makes more sense than the previous behaviour, GwtLoginServiceImpl is not in the project. On 8 abr, 18:52, Ivan M wrote: > Sorry, too fast.

Re: how to make gwt eclipse plugin compiler see other projects
Could you (or somebody) be more specific about this?. I can't run the project in hosted mode, I get the following error: java.lang.IllegalStateException: No such servlet: GwtLoginService The service is in another project and it looks like it isn't started when starting the main project. I have ticked the GwtLogin in Eclipse's Project References of the main project. Also, I have added this to the "web.xml" of the main project: gwtLoginServiceImpl x.gwtlogin.server.GwtLoginServiceImpl GwtLoginService /gwtlogin/GwtLoginService I have copied the module from GwtLogin to the main project, excluding the server implementation.

Re: Trying to use server in another module
Sorry, too fast. I made it work including "x.gwtlogin" in "x.dt" as a module with no entry point. I didn't need to copy the server classes, so I have a single server as I wanted.

Trying to use server in another module
Hello all, I'm facing my first GWT development. I had the idea of developing a project with a module which I have called "x.gwtlogin". The server of this module can perform queries on a LDAP server. My idea is to have an instance of this module running in the application server and use its server from any other GWT application I develop. Let's say one of these applications is "x.dt". I have copied all "x.gwtlogin.client" classes that implement the server's interfance in this application, so now I have two client packages in the project: x.dt.client x.gwtlogin.client The problem is that when debugging in hosted mode wherever I try to use a "x.gwtlogin.client.Class" in a "x.dt.client.Class", I get the following error: [ERROR] Line 20: No source code is available for type x.gwtlogin.client.Class; did you forget to inherit a required module? I suppose the problem is that GWT is not compiling and including the classes in "x.gwtlogin.client" when building "x.dt.client". What can I do?. Is what I intend to do possible at all?.

Thank you, Thomas. I perform authentication against a rather slow LDAP
server, so I can't afford querying this server for every GWT request.
I'm considering tickets but I still don't know how to implement it. I
understand I can use the following as the ticket, so I don't need to
pass an extra parameter:
getThreadLocalRequest().getSession().getId()
I don't want the trouble of storing tickets and their access permits
in the DDBB. Since I read there is one instance of the server running
for all clients, I suppose I can store them in a data structure in the
server. How can I detect that a session has been closed or expired, to
delete the record from the structure?.
Thanks again.

Re: Approaches to develop a stateful application
Being a newbie I can't fully understand the superiority of the client- side approach over Magius' session solution. As far as I understand, keeping the user's credentials in the client means they must be sent to the server and this must verify them in every service request. However, with Magius' solution, verification can be done once for the entire session. Where am I wrong?.
