Robin ,awesome book

i wonder why they didnt include Chrome in honeycomb? where its already included in Google Tv that is based on Android.


Mobile Firefox is more html5 compatible. I checked on that page. Seems like Windows Phone is worse than Android. Low Html5 compatibility has to be a problem for app developers.

Thanks Robin ,superb info !

Congratulations in your new book !!!

Is there a web site of fully/partially supported HTML(5) tags and attributes for various versions of Android ?

Which Browser will the best in your opinion?

Thanks.

Hi Robin,

The support for HTML5(Chrome is OK) in Android Phones and Tablets depends only in the browser,what about the hardware?

Cheers!

Try this example ,just for your question.

Also try EJB 3 Developer Guide by Michael Sikora PACKT press 2008.

Hi

I read this article:


https://glassfish.dev.java.net/javaee5/ejb/EJB_FAQ.html#AppClientDef


I think the answer is close but I don't hava a clear picture.

Thanks Jaikiran and Venkatesh

I'm with GlassFish(APPServer 9)That comes bundled whit

Netbeans 5.5.1.

I tried @Stateless(name="XXX")
and the lookup("XXX") the same error.

As you say the jndi.properties have something to do whit the error.

I'm running Btest.java(Where lookup() is ) as a console application,

but inside the IDE and in the same ejb directory of the Stateless Bean.

This a stand-alone client a POJO BTest.java trying a lookup() in
the Session Bean BBean.java the error is :
javax.naming.NoInitialContextException.
I need to fix the JNDI lookup()


A project
|
|
A-ejb
|
|
Source Packages
|
|
ejb
|
BBean.java
BRemote.java
BTest.java
Right click ejb New------>File/Folder----------->Java Classes-------->Java Main Class

Creates a new Java class with a main method permitting it to be run as a console
application.

The Remote interface(I tried also with Local interface ,same result) :

package ejb;

import javax.ejb.Remote;
public interface BRemote{ }






The Session Bean :

package ejb;
import javax.ejb.Stateless;
@Stateless(name="X")
public class BBean implements ejb.Remote{
public BBean(){ }
}



Is a useless Bean ,but my point is to try the Context with BTest.java







OK this Btest is a POJO so i can not use Direct Injection,I will try l to get the Context.

package ejb;
import java.util.loggin.Level;
import java.util.loggin.Logger;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;

public class BTest{
public BTest(){ }
public static void main(String [] args){

BTest cc=new BTest();
BRemote dd=(BRemote)cc.lookupX();
}
private BRemote lookupX(){
try{
Context c=new InitialContext();
return (ejb.BRemote)c.lookup("java:comp/env/ejb/"X");
}catch(NamingException ne){

Logger.getLogger(getClass().getName().log(Level.SEVERE,"exception caught",ne);
throw new RuntimeException(ne);
}


}end of class





Then I deployed A project OK no problem
I go to Run File (Shift +F6) :Run BTest.java

I got:
ejb.cc lookupX

Severe: exception caught

javax.naming.NoInitialException


This lookupX() was generated by the IDE
right click in the BTest{} class-------Enterprise Resources--->Call Enterprise Bean

How can I get it right with Netbeans?

The tutorial is great and works,but in this simple code not.

Thanks.




Hi Dario I'm using netbeans 5.5.1 & java 6.

I've got tis information:

If you want to use a no-arg InitialContexr()

you need to put a "jndi.properties" file in your app client.

In my server GlassFish that file is empty.

(jndi.properties is inside $glassfish.home/lib/appserv-rt.jar)

I'm trying to set the jndi properties inside appserv-rt.jar so them

will be picked up.........


Application Server > Resources > JNDI > Custom Resources > Beta

Edit Custom Resource
Edit an existing JNDI custom resource.

JNDI Name:Alpha

A unique identifier; contain only alphanumeric, underscore, dash, or dot characters

Finally

This is an EJB proyect(not WEB component)

src/Source Packages/ejb

In ejb packeges there is the SessionBean ,the remote interface(I tried

the local interface also) and the POJO wlth the main(String [] args){

trying ic.lookup(("Alpha")

The problem is that maybe netbeans is already setup for the InitialContext and not allow POJOs to lookup()?

Thanks


Hi
Please I need help with NetBeans ,running GlassFish & EJB3.


The Remote Interface:


package ejb;
import javax.ejb.Remote;

/**
* This is the business interface for AdiosNY enterprise bean.
*/
@Remote
public interface AdiosNYRemote {
public String Mensaje();


}






The Stateless Bean:


AdiosNYBean.java
*
* Created on May 26, 2007, 4:20 PM
*
* To change this template, choose Tools | Template Manager
* and open the template in the editor.
*/
package ejb;
import javax.ejb.Stateless;
/**
*
* @author HANDAL
*/
@Stateless(mappedName="Alpha")
public class AdiosNYBean implements ejb.AdiosNYRemote {
public String Mensaje(){
System.out.println("Viva el Peru");
return "Peru tierra de Heroes";

}

/** Creates a new instance of AdiosNYBean */
public AdiosNYBean() {
}

}





The POJO trying to get the Context:



/*
* TestAdios.java
*
* Created on May 26, 2007, 4:27 PM
*
* To change this template, choose Tools | Template Manager
* and open the template in the editor.
*/
package ejb;
import java.util.Properties;
import javax.naming.InitialContext;
/**

public class TestAdios {


/** Creates a new instance of TestAdios */
public TestAdios() {
}
public static void main(String [] args)throws Exception{

InitialContext ic=new InitialContext(props);
AdiosNYRemote ad=(AdiosNYRemote)ic.lookup("Alpha");


}

Hi Dave

You are right.I'm trying to get the right one setProperty:

Properties props = new Properties();
props.setProperty("java.naming.factory.initial",
"com.sun.enterprise.naming.SerialInitContextFactory");
props.setProperty("java.naming.factory.url.pkgs",
"com.sun.enterprise.naming");
props.setProperty("java.naming.factory.state",
"com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl");

// optional. Defaults to localhost. Only needed if web server is running
// on a different host than the appserver
props.setProperty("org.omg.CORBA.ORBInitialHost", "localhost");

// optional. Defaults to 3700. Only needed if target orb port is not 3700.
props.setProperty("org.omg.CORBA.ORBInitialPort", "3700");

InitialContext ic = new InitialContext(props);

Where can I get the appservrt.jar's jndi to look the right property?

I'm using netbeans 5.5 & GlassFish

Thanks a lot.



Hi

I'm using GlassFish &NetBeans 5.5,no problems at all but

when it comes to a SessionBean(that is the name of the Session Bean) with only one method public String Hello(){return "HelloWorld";}

I tried the standalone client java class accessing public String Hello(){} ,but I can not get the Context.

class Test{

public static void main(String [] args)throws NamingException{
Context ctx=new InitialContext();
SessionBeanLocal hello=SessionBeanLocal)ctx.lookup("ejb/SessionBean");
System.out.println(hello.Hello() );
}
}


I got NoContextException ,both the SessionBean ,SessionBeanLocal& class Test are in the same

ejb directory.The problem is the lookup("What is the right JNDI name in here ???")

I'd appreciate any help.
