Simple Client to EJB application

Hi,
I'm new to EJB.
I have J2EE SDK 1.4 beta installed on a windows 2000 pc.
I have several books with simple examples of clients accessintg simple EJB servers, but none show an example calling an EJB deployed in the application server in the J2EE sdk (Weblogic and Jboss are used in the examples)
Also, there does not seem to be an example of this in the j2ee 1.4 tutorial that I downloaded from sun.
The problems arise trying to make contact with the EJB (what JNDI settings etc are required for the sun 1.4 beta application server?)
My questions are:
Is there a simple example of this available anywhere. Detailing the settings for accessing the EJB on the sun j2ee 1.4 beta application server.
Is there good information on what settings are required in deploytool to perform this.
Is there a good description/explanation of what deplotool actually does under the covers. And whether it is possible to perfor these tasks manually.
Can I just run the client code, or do I need to run it in some for of client container (ie appclient.bat).
Thank you
Colin

The J2EE 1.4 Tutorial currently posted is a beta version and is incomplete. For EJB,
it only covers the deltas between 1.3 and 1.4. The complete tutorial, including a
chapter with a CMP example, will be posted on our web site at the end of this
month. The tutorial explains how to create apps with the deploytool because it's
almost impossible to create a correct EJB deployment descriptor (DD) by hand.
The DD for the tutorial's trivial CMPRoster EJB JAR, for example, is over
1,000 lines long.

Steps to deploy an ejb application and running an ejb client in weblogic server6.1

steps to deploy an ejb application and steps to run an ejb client in weblogic server6.1
if the client is an simple java application and if the client is a servlet

Hi.
Check out the beanManaged example that ships with WLS and read the accompanying docs. This
is a simple EJB with a servlet that invokes it.

How to run application client of an EJB application?

Hi,
My EJB application is deployed on websphere. I have written a small java client program to interact with an EJB which is working fine if I compile and run it in websphere studio environment.
However I am getting runtime exception when I tried to run it at command line.
RemoteConn.java

import com.deque.HelloJavaHome;
import com.deque.HelloJava;
import javax.naming.InitialContext;
import javax.naming.Context;

public class RemoteConn {
public static void main(String[] ar) throws Exception{

String greeting = "";
try{
Hashtable env = new Hashtable();
//env.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.websphere.naming.WsnInitialContextFactory");
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.ws.naming.util.WsnInitCtxFactory");
env.put(Context.PROVIDER_URL, "iiop://localhost:2809");
InitialContext initContext = new InitialContext(env);
Object obj = initContext.lookup("ejb/HelloJavaHome");
HelloJavaHome home = (HelloJavaHome) javax.rmi.PortableRemoteObject.narrow(obj, HelloJavaHome.class);
HelloJava remote = home.create();
greeting = remote.getGreeting(name);
catch(Exception e){
e.printStackTrace();
System.out.println("Greeting::"+ greeting);
I have set the application ejb client jar in the class path of client program.
The exception I am getting at runtime is

Initially I thought I shuold set some jar file of websphere in the classpath of client. But I did not find such a jar containing the above class in websphere studio.
Basically the error is generated at the below statement at runtime.
Object obj = initContext.lookup("ejb/HelloJavaHome");
The only difference I discovered was that the client application has a descriptor file (application-client.xml ) available to it when it ran in websphere studio,. I guess the same META-INF should be provided to client when it runs at command line.
Right now I am not using any client descriptor file to run the client program. If the above error is due to not supplying META-INF to the client application, how should I make this folder available to client at runtime?
I greatly appreciate if I could get help ASAP.
Thanks

Hey got what is going on. In order to invoke EJB, deployed on WebSpehre App Server, from application client we need to install either WebSphere Application Pluggable Client or WebSphere Thin client on the workstation. Pluggable client is a wrapper to SUN JRE where as Thin Client uses IBM JRE.

How to create the simple EJB Applications.

Hi
I have asked about the what are the necessary softwares required for creating the Simple EJB Applications.
I have
Jdk 1.6,
Netbeans 5.5,
J2EE5 ,
Apache Tomcat 5.5
what are other necessary softwares?please tell me From where i get the source code samples?
Please Tell me it is necessary for me..

Hi U,
Tomcat is only JSP/Servlet container -- no EJB support.
Easiest is to download the Netbeans 6.1 bundle including Glassfish and JavaDB, thats all you need + JDK and Java EE of course.
Glassfish has both web/JSP/Servlet-container and EJB-container, so Tomcat is not needed then.
( If for some reason you really want to use Tomcat, you can use it together with OpenEJB for example, to add EJB-support. )

How can I deploy a simple stateless ssion EJB and call it from a standalone client

I'm creating s simple staless session EJB that has a method that takes a name and prints "Hello" + name. This EJB is in a package called "com.demos.mydemo.ejbs.hello"
How can I deploy this to OC4J?

Nabil -
Your standalone client needs to obtain certain server-dependent properties. You can provide them in your code or grab them via a properties file.
For Orion - you need essentially the following setup, filling in your own information...
Define your standalone client class with "main" etc (this is orion specific - should work for 9i AS as well - perhaps there are some differences)
public class SomeClass {
try {
Properties p = new Properties();
p.setProperty("java.naming.factory.initial",
"com.evermind.server.ApplicationClientInitialContextFactory");
p.setProperty("java.naming.security.principal","server_admin_name");
p.setProperty("java.naming.security.credentials","server_password");
// THEN you can get your intitial context reference
InitialContext initial = new InitialContext (p);...........
Then go about your business.....
A good book to get is called "Professional Java Server Programming J2EE Edition" - there happens to be a reasonable amount of Orion/OCJ4 centric information since one of the authors is Karl Avedal - one of the principals behind Orion. Go out to java.sun.com and look at some of the J2EE tutorials - unfortunately a lot of it is hidden behind the J2EE Deployer, but you will get a good sense of what goes into outside-the-container standalone clients.

EJB Application Client clarification

Hi EJB Guru,
I would like some clarification on accessing Remote/Local Session Bean using an Application Client. In other word,
there appears to be more than one approach to the same Session bean. Let's start by declaring the Converter EJB:
package converter.ejb;
import java.math.BigDecimal;
import javax.ejb.Remote;
@Remote
public interface Converter {
    public BigDecimal dollarToYen(BigDecimal dollars);
    public BigDecimal yenToEuro(BigDecimal yen);
package converter.ejb;
import java.math.BigDecimal;
import javax.ejb.Stateless;
@Stateless
public class ConverterBean implements converter.ejb.Converter {
    private BigDecimal euroRate = new BigDecimal("0.0070");
    private BigDecimal yenRate = new BigDecimal("112.58");
    public BigDecimal dollarToYen(BigDecimal dollars) {
        BigDecimal result = dollars.multiply(yenRate);
        return result.setScale(2, BigDecimal.ROUND_UP);
    public BigDecimal yenToEuro(BigDecimal yen) {
        BigDecimal result = yen.multiply(euroRate);
        return result.setScale(2, BigDecimal.ROUND_UP);
}I have two method to accessing this bean.
( i ) Lookup JNDI using the following set of code:
package converter.client;
import converter.ejb.Converter;
import java.math.BigDecimal;
import javax.ejb.EJB;
import javax.naming.InitialContext;
import javax.naming.Context;
import javax.naming.NamingException;
public class ConverterClient {
    public static void main(String[] args) {
        try {
            InitialContext ctx = new InitialContext();
            ConverterRemote jndiconverter = (ConverterRemote) ctx.lookup("converter.ejb.ConverterRemote");
            BigDecimal param = new BigDecimal("100.00");
            BigDecimal yenAmount = jndiconverter.dollarToYen(param);
            System.out.println("$" + param + " is " + yenAmount + " Yen.");
            BigDecimal euroAmount = jndiconverter.yenToEuro(yenAmount);
            System.out.println(yenAmount + " Yen is " + euroAmount + " Euro.");
            System.exit(0);
        } catch (javax.naming.NamingException ne) {
            System.err.println("Caught an unexpected exception!");
            ex.printStackTrace();
}( ii ) Application Client lookup?
package converter.client;
import converter.ejb.Converter;
import java.math.BigDecimal;
import javax.ejb.EJB;
public class ConverterClient {
    @EJB
    private static Converter converter;
    /** Creates a new instance of Client */
    public ConverterClient(String[] args) {
    public static void main(String[] args) {
        ConverterClient client = new ConverterClient(args);
        client.doConversion();
    public void doConversion() {
        try {
            BigDecimal param = new BigDecimal("100.00");
            BigDecimal yenAmount = converter.dollarToYen(param);
            System.out.println("$" + param + " is " + yenAmount + " Yen.");
            BigDecimal euroAmount = converter.yenToEuro(yenAmount);
            System.out.println(yenAmount + " Yen is " + euroAmount + " Euro.");
            System.exit(0);
        } catch (Exception ex) {
            System.err.println("Caught an unexpected exception!");
            ex.printStackTrace();
}It is the first time I come a cross method ( ii ) and could not get it to work properly. The error message
received were:
SJSAS server side

asadmin>My questions are:
( a ) Why does the error occur?
( b ) what is the architecture difference in accessing the same bean? Does JNDI lookup allows one to access EJB from remote host as opposed the method ( ii ) which is only restricted to local access on the same JVM/Container?
( c ) What are the pros & cons between the two?
I am using Application Client to lookup these Session Beans on Netbeans 5.5, SJSAS 9.0, SDK 1.5.0_11 on Windows XP platform.
Any guideance/advice would be very much appreciated.
Thanks alot,
Henry

Hi, may be you can help me with a similar problem that I have, I transcript the post in the netbeans forum, I really hope that you or someone can help me with this. Thanks in advance!
I hope that somebody can help me solving this issue.
Environment:
NetBeans 6.0 beta1 + glassfish b58g fresh installed
Windows XP
Make a new enterprise application with application client. Run the empty Main and it runs ok.
Now create a Stateless Session Bean with hello method.
In the Application Client Main insert a reference to the EJB using the wizard. (@EJB etc...)
invoke the hello method from the main().
right click on libraries from application client and add the application-ejb project
Deploy and it deploys ok, but when you run it throws an exception:
client:
java.lang.NullPointerException
server:
Error in annotation processing: java.lang.NoClassDefFoundError: Lorg/arautos/revista/sacrae/server/business/SACRAEFacadeRemote;
java.io.FileNotFoundException: C:\opt\glassfish-v2-b58g\domains\domain1\applications\j2ee-modules\SACRAE-app-client\SACRAE-ejb.jar (El sistema no puede hallar el archivo especificado)
Remember we added the project to the appclient libraries. If I place the missing file in the applications directory of glassfish it wont work, because when you run it, deploying on the server will erase it again. But, if you copy the jar file in the directory and open it with 7zip or any other application that can keep the file open, when you run it again it will work (because the server is not able to delete the file).
Although this is a workaround, there should be something I am doing wrong to cause this behavior, now when I try to use Java Web Start to execute the client it fails (surprisingly) with this exception:
java.lang.reflect.InvocationTargetException
Caused by: java.lang.NoClassDefFoundError: org/arautos/revista/sacrae/server/business/SACRAEFacadeRemote
at org.arautos.revista.sacrae.client.desktop.Main.main(Main.java:30)
... 21 more
And I don't know where in the domain1 directory place the jar, worse, I don't know how to solve the issue with the ejb-jar in the first place, does anybody has an idea, link, same problem? I have googled, netbeans-ed and java.net-ed a lot but didn't find anything :(
Thanks in advance for any help.
Best Regards.

Calling a webservice from weblogic EJB Application

Hello,
I have a webservice running on IIS server. I created a simple java client program to call the webservice and it works fine. However, when I wrapped the same java client program as a EJB Application, I am unable to call the webservice.
I get the following error:
####<Apr 3, 2007 1:59:30 AM CDT> <Info> <WebService> <CASEJBServer> <ExecuteThread: '24' for queue: 'weblogic.kernel.Default'> <<anonymous>> <> <BEA-220094> <An IOException was thrown trying to access the WSDL at the given URL.>
And
"java.io.FileNotFoundException: Response: '401: Unauthorized' for url: XXXXXX"
Could you please give some simple steps as what are the JAR Files required to be included in the Weblogic Server's classpath to call the webservice.
Thanks.

To start off you need to make sure that your client api is in the classpath, either in your ejb or your ear or the server classpath.
The other concern I would have is that it seems you are just not authorized to access the URL.
- Does the WSDL require credentials? So in other words when you go to the URL are you allowed to access the WSDL without athenticating.
- How does your Impl get created?
MyServiceImpl service = new MyServiceImpl()
If you are using the empty constructor then what is the wsdl endpoint in your jar file since that is the wsdl it will use. If the endpoint is localhost/xxx/xxx then you will have issues since that means your not deployed on localhost. What url is at the endpoint? Do you have access to the url from your server?
If you are using "new MyServiceImpl(url);" then again is the wsdl locked down because in this case you will need to do somthing like http://username:[email protected]/xxx?wsdl
Hope this helps.

Jdk 1.2 clients running ejb deployed on oracle 8.1.5

Oracle claims that it is possible to run jdk 1.2 clients with ejb on oracle 8.1.5 in the faq : http://technet.oracle.com/products/oracle8i/htdocs/jserver_faq/815faq0012.html
If you have JDK1.2 on the client side and:
8.1.5 clients connecting to an 8.1.5 server: This does not work, because of conflicts with the ORB supplied in JDK1.2.
8.1.5 clients connecting to an 8.1.6 server: This does not work, because of conflicts with the ORB supplied in JDK1.2.
8.1.6 clients connecting to an 8.1.5 server: This works provided the "server" portion of the application is developed/loaded using the client side tools and jars that are supplied with 8.1.5.
What do they meen with 8.1.6 clients? and how to make 8.1.6 clients?

Oracle 8.1.6's JVM uses JDK 1.2. Oracle's 8.1.6 JDBC drivers support JDBC2 and JDK2. The 8.1.6 drivers are available for download from OTN under the Technologies section.
If you develop a client (application, applet, servlet, JSP, etc.) using the Oracle 8.1.6 JDBC drivers, then this is considered an Oracle 8.1.6 client.

What is the directory structure of EJB applications?

I am new to EJB program. I know that after the development is done, we package the EJB components into .jar file, and package the Web components (HTML/JSP/Servlets/JavaBeans) into .war file, and then together we package .jar file and .war file into a single .ear file. Then we just deploy the .ear file into WebLogic's application directory.
But, before the deployment, I mean during the development, what kind of directory structure is good for us to develop our EJB, HTML, JSP, Servlets, and JavaBean components?
Previously, when I was doing JSP/Servlets applications, my directoy structure is:
webapps\
--------myapplication\
-----------------------*.html
-----------------------images\
------------------------------*.jpeg, *.gif
-----------------------jsp\
------------------------------*.jsp
-----------------------WEB-INF\
------------------------------web.xml
------------------------------classes\
-------------------------------------Java Servlets located here
-------------------------------------beans\
-------------------------------------------JavaBeans are located here
Now, I am doing EJB applications, what should be the directory structure?
Thank you very much for your help!

I have been involved in a few enterprise applications but have not been happy with the packaging structures used and am starting a new one now and am looking for other examples.
this is what I've used before.
web/
classes/
client/
server/
but if a class was used in the client and server it was put under the server/ package. I feel that more separation is needed.

Need a help to create ejb application in netbeans with weblogic 9.2

Hi guys,
I am new to EJB..can anyone guide me to create a EJB application in netbeans 5.5 with weblogic server 9.2 ..
thank u in advance..

Hi guys,
If there is no one to help me with this so simple project then I will have to quit trying. I am getting to much pressure to get this done and I just don't know how to proceed anymore. I have found a document on OTN that explain the basics of binding but it's to vast and too complicated under pressure. If someone could help me to bind this LOV I would appreciate this so much and then I could relax a little and read all the good documents that I have found on OTN.
This is my last chance.
Thank you!

Consume Web Service in EJB Application

Hi Experts,
I have EJB Application with some Java Classes.My Requirement is to Consume Web Service in EJB Application.
I am new to EJB Application.Please share if have any ideas regarding the same.
Thanks & Regards,

Hi Vijay,
Thanks for the Reply.
Please provide the JAR Files i need to add.
I had tried to consume the web service by using the java class in Java Project ie EJB.
After creating the Project i will import the WSDL file in that Project and create the Client Application.
The Request and Response java class is created by importing the WSDL file.
The Client Java Class is created to access the Request and Response objects.
After this Main class is created and I have run the application to execute the Client Java Class. During this time its shows some error.
The Error Message are:
