Re: GWT using a Stateful EJB in the HTTP Session via a Servlet | Dobesland

Targe — Mon, 19 Oct 2009 16:17:36 -0000

En el servidor RCP
public class ServiceSessionImpl extends RemoteServiceServlet implements ServiceSession {
private static String strVersion = "ServiceSessionImpl";

private Usuario usuarioObj = new Usuario();
private UsuarioDao objUserDao = new UsuarioDao();

public Usuario getUser() {
usuarioObj = new Usuario("loginprueba","passprueba",true);
//usuarioObj = objUserDao.getPruebaDato(String Sql);
HttpServletRequest httpSession = this.getThreadLocalRequest();
HttpSession session = httpSession.getSession();
session.setAttribute("usuario",usuarioObj);
Usuario usua = (Usuario) session.getAttribute("usuario");
return usua;
}
........
}

public interface ServiceSession extends RemoteService {
public static final String SERVICE_URI = "servicesession";

public static class Util {

public static ServiceSessionAsync getInstance() {

return GWT.create(ServiceSession.class);
}
}

public Usuario getUser();
......
}

public interface ServiceSessionAsync {
public void getUser(AsyncCallback<usuario> callback);

...
}

El el cliente le llamo asi

public class Bprueba extends CPanel {

/* (non-Javadoc)
* @see ISO_OLADE.client.CPanel getViewPanel()
*/
public String getSourceUrl() {
return "source/grid/LocalPagingSample.java.html";
}

public Panel getViewPanel() {
Panel panel = new Panel();
panel.setBorder(false);
panel.setPaddings(15);
panel.setTitle("Lugar");

ServiceSessionAsync service = (ServiceSessionAsync) GWT.create(ServiceSession.class);
((ServiceDefTarget) service).setServiceEntryPoint(GWT.getModuleBaseURL() + "servicesession");
AsyncCallback callback = new AsyncCallback()
{
public void onSuccess(Object result)
{
Usuario user=new Usuario();
user=(Usuario)result;
System.out.println("onSuccess = Usuario return del RPC"+user.getSNombre());
}
public void onFailure(final Throwable caught)
{
System.out.println("Failure=Usuario return del RPC");

}
};
service.getUser(callback);

return panel;
}

Una vez que ejecuto en el cliente hostemode me devuelve "onSuccess = Usuario return del RPCpassprueba" que es correcto pero mi problema
es como poder usar el Object result que devuelve el RCP en las otras paginas del cliente sin necesidad de volver a llamar al service.getUser(callback); en realidad hacer uso del
HttpSession session = httpSession.getSession(); que se creo en la clase ServiceSessionImpl

Espero que me puedas ayudar
Mil gracias

Re: Faster GWT startup with objects embedded in the HTML host page

dobes_vandermeer — Mon, 24 Aug 2009 16:41:47 -0000

Sure, here's an example:

interface MyInitialData extends DictionaryConstants {
// ...
}

MyInitialData initialData = new MyInitialData() {
@Override
public UserInfo myUser() {
return myUser;
}
@Override
public AuthToken sessionToken() {
return token;
}

};

request.setAttribute("initialData", DictionaryConstantsWriter.serializeConstants("initialData", initialData, MyInitialData.class, true));

Then I use this inside a freemarker template as ${initialData}, along with the usual GWT stuff.

Re: Faster GWT startup with objects embedded in the HTML host page

Jim — Mon, 24 Aug 2009 16:27:10 -0000

Any chance you could post an example of how to use the DictionaryConstantsWriter class. I think this could be useful in decreasing the load time for one of my GWT components which contains several input picklist fields, each resulting in a RPC call back to the server at load time. An example would be greatly appreciated.

Re: Running Work in a Seperate Thread and Transaction in Glassfish using the WorkManager

dobes_vandermeer — Tue, 16 Jun 2009 13:07:20 -0000

Hi Vamsi,
This is a glassfish-specific API that is not a standard, and is not
available in other containers as far as I know.

Hope that helps (or not!).

I don't know if WorkManager has a waitForAll() method, you'll just have to
go take a look at the source code and see what is there for use.

If you just want to run some jobs in a bunch of threads you can use the
standard Thread and ThreadPool APIs as well, WorkManager doesn't do anything
special except manage a list of "Work" objects and run them for you when the
thread is available.

Re: Running Work in a Seperate Thread and Transaction in Glassfish using the WorkManager

Vamsi Mandava — Tue, 16 Jun 2009 05:34:48 -0000

Hi All,

Is this Workmanager API compatible to JSR-237?
I am missing some methods like waitForAll() in WorkManager?

Is there any implementation simillar to Weblogic or Websphere work manager for glass fish?

Hi,
this was a really annoying problem, and I would be perfectly fine even without dtd check.

Thank you a lot for this fine solution.

Re: Glassfish: Setting the context-root of a WAR inside an EAR | Dobesland

dobes_vandermeer — Thu, 23 Apr 2009 12:35:07 -0000

Did you try using an empty string? I'm not sure what else might work.
Another option is to set the war as the "default web application" in the
glassfish admin panel, I believe it's the virtual server configuration that
lets you do that.

I've already known than the file is applicattion.xml, but my problem is that I want to set me root context to "/", but when I deploy it, and enter the URL like http:localhost:82/ (thats de URL), then, it don't load the applicattion, so I don't know how to set the root context into "/" and make it work.

Ane help?

Hi Joe - I haven't done that, I am using glassfish java.logging. This tip
shows how to redirect other logging systems like log4j and commons-logging
to use java.logging within glassfish.

Can you show how you have moved glassfish javalogging to another system?

You should make a class called Lexicographer. A lexicographer is a person who writes dictionaries.

Re: Running Work in a Seperate Thread and Transaction in Glassfish using the WorkManager

dobes_vandermeer — Sun, 15 Feb 2009 20:43:17 -0000

Hello Lee,
In eclipse I just type "WorkManagerFactory" and press CTRL+SPACE. The
WorkManager implementation is here:

import com.sun.enterprise.connectors.work.CommonWorkManager;

You can just use new CommonWorkManager("thread-pool-name-here") to construct
it; this is basically what the WorkManagerFactory does except it allows you
to set a different implementation of WorkManager if desired.

The "Work" interface is here:

import javax.resource.spi.work.Work;

Note that these won't be available unless you have appserv-rt.jar in your
classpath.

Hope that helps!

lee_wright — Sun, 15 Feb 2009 20:27:59 -0000

Why under netbeans am I unable to find the WorkManagerFactory class?
Do you have a full example (including imports) of the code snippet?

Thanks

Lee

Re: Just when I thought the past would disappear

The Red Rover concept was a lot of fun to play with lots of people. I played it on the servers I helped admin that were popular at the time (still a little popular with CoD4). I didn't ever package it up so that I could distribute it properly. For CoD I create http://www.bigbrotherbot.com which is still used today for other Quake mods. Something I need to revisit to get up-to-date.

Heh, houseplans, another crossover. I don't plan to write accounting software but do plan to check out Clarity Accounting again soon. I don't do much freelance anymore though, just started working for a company in Austin and am trying to get into iPhone apps. If you have time, since you are an experience Objective-C programmer, let me know :). There's a few iPhone apps in my pipeline, including one with a bounty at my work.

Re: Just when I thought the past would disappear

I followed the links and mucked around on your blog. I looked at your 2001 DobesLand and found that apparently we were both modding games around the same time. What I find amazing is that I also created Red Rover for Call of Duty, albeit 5 years after you did, but the same concept exactly.

The earliest personal site I can remember was in 1997 hosted on my ISPs space http://web.archive.org/web/.... The funny thing is it stayed active till 2004 even though I stopped updating it in 2000 and left the host much sooner than 2004.

It was about the time I was working on my first professional PHP site, Allplans.com, http://web.archive.org/web/.... It started on it a couple years before and left the company at the end of 2001 where the wayback machine shows it getting progressively worse. Funny thing is that I met up with the guy who owns the site early last year and started the process of tacking the site back over. After 2001 I started working on dozens of sites I can't remember.

Re: Just when I thought the past would disappear

dobes_vandermeer — Fri, 09 Jan 2009 01:17:07 -0000

Strange parallels!

Red Rover was a lot of fun to play, although you needed to have a lot
of people (it was quite pointless with less than 4). Was your CoD mod
actually called "Red Rover" ? I played a lot of Call of Duty back
when it came out. Later I moved onto Counter-Strike and then Call of
Duty 2 for a while. I guess I've been a multi-player FPS junkie for
quite a while ...

My AAI term project was to write software to auto-generate home floor
plans, not long before you would have been working on allplans.com,
for what that's worth.

Are you going to make accounting software next ? :^P
