How to develop EJB 3.0 Session Beans under WL Workshop 10.3?

Hi there,
I know the theory about EJB, no problem there, but I've been trying to develop some EJB's on WLW, and I'd like to ask you two things:
1. Is there any guide to follow? I found this web page, but I feel it's not quite enough.
2. How do you do to make code-completion working for the EJB (or any other) annotations? I write @javax. CTRL-Space and it starts completing, but it does not add the founded class to the class' imports.
Thanks in advance for any tip!

Creating EJB 3.0 Session Bean under JDeveloper 10g.

Hello im using JDeveloper 10 g all up 2 date.
when i create EJB 2.x EJB everythink is ok .. there is a Wizzard(Designer) from which i can add methods variables and etc.
all methods are become added to the session bean / remote interefeis etc.
My Problem is when i create EJB 3.0
when i do it the Bean class is created and the Remote interfeis with @remote is created too its ok BUT I CANT see Remote interfeis in my Application Naviagation its fine under 2.1 i cannot see remote interfeis and home interfeis too but inder 2.1 there is a wizzard(Designer) under 3.0 there is nothink.
what am i wrong ? how can i make designer to work under 3.0 or how can i make Jdeveloper to show me all content of the EJBs

another strange problem.
i have an APplication server added ( JBOSS ).
when i create deployment profile (EAR ) application server is showed in the ComboBox .
But when i create Java Test Client for some EJB and when i check " Connect Remote Application server" there is 2 comboboxes
J2EE Application
App Server Connection.
first combo is ok there is EJB applicaiton
Secound is empty .. but i Have App Server.
Another think is that when i create EJB 3.0 its BAD to see J2EE app it must be J EE 5 app or just Java EE app

How create EJB 2.1 Stateful Session Bean in a EJB 3.0 Session Bean

Hi All,
We have been developing on EJB 2.1. We are now adding a module on EJB 3.0.
How can we "create" a stateful session bean with create method signature similar to create(String id)?
We have tried
// this is the remote interface
@EJB AddressBean abean;
But not working
Any help will be appreciated.

There is no explicit create() call for EJB 3.0 session beans. It doesn't really matter though
since you can accomplish the same thing by defining your own business method to act
as an initializer for whatever state you'd like. E.g.
@Remote
public interface FooInterface {
public void initialize(String id);
// ... other business methods
@EJB FooInterface fooRef;
fooRef.initialize("foo");
--ken

How to lookup a EJB 3.0 session bean which is deployed in WebLogic 10.3

Now Jdeveloper 11.1.1, is giving WebLogic server 10.3.
With internal WebLogic server, when I created a Sample client, it generated code as:
private static Context getInitialContext() throws NamingException {
    Hashtable env = new Hashtable();
    // WebLogic Server 10.x connection details
    env.put( Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory" );
    env.put(Context.PROVIDER_URL, "t3://127.0.0.1:7101");
    return new InitialContext( env );
public static void main(String [] args) {
    try {
        final Context context = getInitialContext();
        DefaultSession defaultSession = (DefaultSession)context.lookup("property-DefaultSession#com.vs.property.model.session.DefaultSession");
    } catch (Exception ex) {
}How to update the above code to lookup the EJB 3.0 session beans with an external WebLogic server 10.3?
Is there any documentation available on how to install weblogic, troubleshoot, debug, WebLogic server 10.3?

Raju,
Hi, to start, here is a tutorial on a quickstart web application using an EJB 3.0 stateless session bean that fronts a container managed EclipseLink JPA entity manager on WebLogic 10.3, you will find references there to other general WebLogic documentation.
[http://wiki.eclipse.org/EclipseLink/Examples/JPA/WebLogic_Web_Tutorial]
using @EJB injection on the client instead of a JNDI lookup as below
[http://edocs.bea.com/wls/docs103/ejb30/annotations.html#wp1417411]
1) in your second env.put I noticed that your t3 port is 7101, I usually use the default 7001 - but It looks like this port is valid for the JDeveloper embedded version of WebLogic server runs - just verify that it matches the port of your server.
2) your name#qualified-name lookup looks ok. Verify that the jndi-name element is set in your weblogic-ejb-jar.xml for non injection clients like the following
<weblogic-ejb-jar>
<weblogic-enterprise-bean>
<ejb-name>ApplicationService</ejb-name>
<jndi-name>ApplicationService</jndi-name>
3) as a test outside of your application - launch the WebLogic admin console and goto the testing tab of your bean in [Home > Summary of Deployments > "application" > "session bean name"

How to get stateful and stateless session bean in second jsp

I create stateful session bean in the first jsp, then how can I get the stateful session bean in the second jsp? I find that somebody store the bean in HttpSession.
If I store the stateful session bean in HttpSession, then I can get it in the second jsp. My problem is that I can store the stateless session bean in HttpSession, and get it in the second jsp. Then, both stateful and stateless can maintain the state in the second jsp. What is the difference between stateful and stateless session bean in this case ?
I understand the definition of stateful and stateless session bean, but I'm confuse how to use session bean. Can anyone provide sample jsp to show difference of stateful and stateless? How the stateful session bean can maintain the state for the client?

Greetings,
I create stateful session bean in the first jsp, then how can I get the stateful session bean in the
second jsp? I find that somebody store the bean in HttpSession.Which is the correct scope for sharing client-specific data when 'request' scope is insufficient.
If I store the stateful session bean in HttpSession, then I can get it in the second jsp. My problem is
that I can store the stateless session bean in HttpSession, and get it in the second jsp. Then, bothWhy is that a "problem"? Does your application not require the stateless bean to be shared? If so, then don't store the EJBObject reference in the session...
stateful and stateless can maintain the state in the second jsp. What is the difference betweenWhat do you mean by this exactly?..
stateful and stateless session bean in this case ?Statefulness of session beans is in regard to maintaining client state (er, in all cases). If your "stateless" bean is receiving information from the client (i.e. its caller) - either through a create method or a business method - and that information is available (retrievable from the bean) on subsequent method calls, then that bean is, in fact, stateful - regardless of how it is deployed.
I understand the definition of stateful and stateless session bean, but I'm confuse how to use
session bean.The correct question, it here seems, is "when" to use which type... Use a "stateful" bean when information about (from) the client (i.e. the caller) must be maintained across method calls of the bean. Use a "stateless" bean for general business methods that do not depend on "prior knowledge" of the client (i.e. the caller).
Can anyone provide sample jsp to show difference of stateful and stateless? How the statefulA "sample JSP" would yield nothing additional... The semantics of calling, using, and "persisting", bean references are always the same - regardless of type or class. However, the reason(s) for using one over the other depends entirely on the needs of your application.
session bean can maintain the state for the client?I recommend that you spend more time learning about EJBs generally. In particular, it seems you require more fundamental understanding of their scope and lifecycle. Refer to sections 4, 6, and 7 of the EJB 2.0 Specification.

How to avoid Invalidation of Stateful Session Bean in case of an Exception?

Hi developers,
I'm working on a project using JSF, Toplink and EJB 3.0 using JDev.

Your question is not how to create/compile a stateless session bean, you are asking how to use those weblogic specific annotations. A weblogic forum is a better place to ask that.

Cannot deploy a EJB 3.0 Session bean to the OAS 10.1.3.4

Hi All,
I am unable to deploy a EJB 3.0 Session bean with no deployment descriptors to OAS 10.1.3.4 App server.This Session bean is also exposed as a web service using annotations. I am able to deploy this bean to a standalone oc4j 10.1.3.x containers and test it successfully.
i have written a simple stateless session bean ( exposed as webservice) and every bean is having issues with deployment having the same exception stated below
Can some one please help as i need to deploy this urgently.
below is the session bean code:
import javax.ejb.Stateless;
@Stateless(name="SiebelQuoteEJB")
public class SiebelQuoteEJBBean implements SiebelQuoteEJBLocal,
SiebelQuoteEJBWebService {
public SiebelQuoteEJBBean() {
public String publishMessage(String message,String type) throws java.rmi.RemoteException {

EJB 2.1 session bean calling EJB 3 session bean?

How can i design a EJB application using session Beans?

Hello,
I am designing a Find application using EJB. Here a user is prompted a search page, where he can enter the search criteria's. Then on click of submit, the query is formed at the server side depending on what criteria's were selected. Then a jdbc query is performed and the results are returned back to the user. Here no session is maintained for the users. Can anyone suggest me how to design this application using EJB. Should i use entity beans for this or session beans will suffice? Should the jdbc query be performed in the bean itself or should it be outside in a helper class? Please kindlu suggest me the design for this application...
Regards,
Subbu

Hi,
First of all, I'm unable to figure out why you need to use EJB for this scenario. You can write a helper class to frame and execute the query.
If you really want to use EJB, then I suggest you use a stateless Session Bean with transaction attribute as TX_NOT_SUPPORTED. From the session bean, you can call the helper class. But, by avoiding the session bean, you can eliminate remote calls, thus improving your performance. Also, check if the database & the db driver you are using supports sql caching.

How to call a EJB method from Session bean method

Hi all,
I'm new to J2EE programming. I have a simple doubt .
I have already created a lookup method for EJB bean in Session bean .
My question is how to call a method of an ENTITY bean (say insertRow) from SESSION bean method(Say invoke_insertRow) .
Please provide me an example code .
Thanks in advance.

InitialContext ctx = new InitialContext();
     GeneralEditor editor = (GeneralEditor) ctx
                    .lookup("GeneralEditorBean/remote");
          GeneralService service = (GeneralService) ctx
                    .lookup("GeneralServiceBean/remote");
          LanMu lm = new LanMu();
          lm.setName("shdfkhsad");
          editor.add(lm);

How do I lookup an EJB 3.0 Session bean from servlet or JSP?

Does anyone knows how can I invoke an EJB from a servlet or JSP ?
I deployed a simple EJB on a Oracle Application Server 10g release 10.1.3 and I'm working with JDeveloper 10.1.3. I deployed the files via JDeveloper, and I didn´t specify any orion-ejb-jar.xml or ejb-jar.xml file
After deployment, the orion-ejb-jar.xml look like this in the server:
<?xml version="1.0" encoding="utf-8"?>
<orion-ejb-jar xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://xmlns.oracle.com/oracleas/schema/orion-ejb-jar-10_0.xsd" deployment-version="10.1.3.0.0" deployment-time="10b49516c8f" schema-major-version="10" schema-minor-version="0" >

<assembly-descriptor>
<default-method-access>
<security-role-mapping name="<default-ejb-caller-role>" impliesAll="true" />
</default-method-access>
</assembly-descriptor>
</orion-ejb-jar>
I'm trying to invoke the ejb in a servlet by doing the following:
public void doGet(HttpServletRequest request, ....
Context context = new InitialContext();
HolaMundoEJB helloWorld =
(HolaMundoEJB)context.lookup("java:com/env/ejb/HolaMundoEJB");
String respuesta = helloWorld.sayHello("David");
When i invoke the servlet I catch a NamingException whose message says something
like this ....java:com/env/ejb/HolaMundoEJB not found in webLlamaEJB
I tried different paths for the lookup but nothing....
Can anyone help me with this topic? Thank you.

Please try the following code:
HelloEJBBean.java:
@Stateless(name="Hello")
@Remote(value={Hello.class})
public class HelloEJBBean implements Hello { ... }
hello.jsp:
Context ctx = new InitialContext();
Hello h = (Hello)ctx.lookup("ejb/Hello");
web.xml:
<ejb-ref>
<ejb-ref-name>ejb/Hello</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
<remote>fi.kronodoc.test.model.Hello</remote>
</ejb-ref>
i think you should also define jndi mappings for the references in orion-ejb-jar.xml and orion-web.xml but for some reason it seems to be working also without these.

JDEV 10.1.3 How to manipulate/Debug IndirectList from ejb 3.0 session bean

I was debugging my session bean a seen that element data for the employeesCollection was empty.
I didn't understood why my java client was throwing an error when i accessed manually the Departments collection and get the employeeCollection from the first entry in the collection. What was confusing me was that my master/detail jfs application was displaying these data. From where ? how was it possible ? it was the same session bean !
This is the reason i debugged the session bean return object and seen that the collection was also empty as the from executing from my java client application. I have seen the type of the object that was not a collection but IndirectList.
So my question ! how is it possible to load the collection of this type ? Which method the data control is executing to load it ? Where may i found a description of this very interesting process ?

Hi Frank.
plain English - on plan :).
I create managed bean with function which do access to LDAP and this function 'return List<Users>'.
In JDeveloper :) on managed bean(java class) i create "Create Data Control"... after, from Data Controls i drop on page this data(create ADF Table with selectOne)...
First Page Ready!
Second page... i need to know which option selected on first page. This option(row) contains, UserName and etc... On second page i again fetch data, from LDAP, associated with this concrete UserName... Because i fetch data using managed bean :) i need to know this username in my managed bean...
May be :) im wrong...
sessionAttribute - like this? ->
* Convenience method for setting Session variables
* @param ctx FacesContext
* @param key object key
* @param object value to store
public static void storeOnSession(FacesContext ctx, String key, Object object) {
Map sessionState = ctx.getExternalContext().getSessionMap();
sessionState.put(key, object);
* Convenience method for getting Session variables
* @param ctx FacesContext
* @param key object key
public static Object getFromSession(FacesContext ctx, String key) {
Map sessionState = ctx.getExternalContext().getSessionMap();
return sessionState.get(key);
}

I used a different method...
I used servicegen with only a.jar to create the ear.
I touch-ed my own application.xml to make it newer than the one already in the
newly created ear.
I used the ant <ear> task to add b.jar, c.jar, and application.xml to the ear.
Worked like a charm.

EJB 3.0 Session Bean Remote Client

Hi,
I am planning to migrate my EJB 2.1 to EJB 3.0. My old session bean is accessed by a remote java client. I just have to include this piece of code:
Hashtable props = new Hashtable();
props.put("java.naming.factory.initial", com.sun.jndi.cosnaming.CNCtxFactory");
props.put("java.naming.provider.url", "iiop://" + host_ + ":" + port_);I also have to generate rmistubs for the ejb. I have deployed my EJB 3.0 in a Sun Appserver, checking the "Generate RMIStubs" box but I couldn't find the client jar file. In EJB 3.0, should I use the same approach as the 2.1? Or should I use the @EJB annotation? How will I access a remote EJB 3.0 using the @EJB annotation? Thanks in advance.
Regards,
Andrew

EJB 3.0 remote business interfaces are do not have the same interoperability requirements as the EJB 2.x Home/Remote view. If you need access to your EJB 3.0 bean from a legacy client, you can add a 2.x-style Home/Remote view to your bean by either using the <home>/<remote> elements in ejb-jar.xml or the @RemoteHome annotation. Note that the 2.x-style Home/Remote interfaces are completely separate from the 3.0 Remote Business interface.
Also, in SUN's implementation if your EJB 3.0 bean has both a 3.0 Remote business and a 2.x Home/Remote interface there is no default global JNDI name for the bean. You'll need to assign it explicitly using the @Stateless/@Stateful mappedName() attribute or sun-ejb-jar.xml.
