Creating Remote Interface using workshop

I created a session EJB using weblogic workshop 8.1 sp3. It autogenerated the remote interface that extends EJBObject, and is uneditable. I want my remote interface to extend com.bea.p13n.property.EntityPropertyManager. How can I create my own remote interface while creating a session bean using workshop? Appreciate your help.

Hi,
I am in the same boat. Did you find any solution to it?.
Thank You.

How to specify a base class for Remote Interface in Workshop 9.2? -- URGENT

Hi,
I am trying to create a UUP EJB in WebLogic 9.2 workshop. I am using @FileGeneration to create my home & remote interfaces. And the generated remote interface is extending javax.ejb.EJBObject;I want my remote interface to extend com.bea.p13n.property.EntityPropertyManager which in turn implements javax.ejb.EJBObject. Can someone tell how i can do it in Workshop?.
I came across Predefined Variable: remote.baseClass and as per docume
ntation..."If specified, the value of this variable will be used as the base class for all generated remote classes. Where i should specify it?. @FileGeneration does nt have any option for it. Any help is grtly appreciated.
Following are my code snippets:
IMPL Class
@FileGeneration(remoteClass = Constants.Bool.TRUE,remoteHome = Constants.Bool.TRUE, localClass = Constants.Bool.FALSE, localHome = Constants.Bool.FALSE,remoteClassName = "MyEntityPropertyManager",remoteHomeName = "MyEntityPropertyManagerHome")
public class MyEntityPropertyManagerImpl extends GenericSessionBean implements
SessionBean {
//code
}

This question was posted to both the bea.workshop.developer.general and weblogic.developer.interest.workshop (I had replied to the later on 10/19); after seeing an identical question today on this list want to include a reference to that reply here:

Obtain remote interface using PortableRemoteObject

Hello,
I have sample code from "Applying Enterprinse JavaBeans" book.
Plan plan = (Plan)PortableRemoteObject.narrow(
it.next(), Plan.class);
... plan.getPlanInfo() ...
here:
Plan is a remote interface of the entity bean (e.g.. MyPlanBean).
getPlanInfo() is one of the business methods in Plan.
In this case, the remote interface is obtained by using PortableRemoteObject.narrow(...). could anyone explane the creation using the concept of life cycle of an entity bean instance? That means if any ejbCreate() methods or any callback methods are involved in the creation or not?
Thanks.

I am not sure if you are doing the right thing.
The home interface represents the life-cycle methods of the component (create, destroy, find) while the remote interface represents the business method of the bean.
Clients use the bean's home interface to obtain references to the bean's remote interface. Following is the life-cycle of
entity bean creation:
1. Client invokes create() on home object
2. Home object allocates a bean from the free pool
3. Home object passes on the create args to the ejbCreate(..)
in the bean
4. the bean inserts a row into the database table
5. the bean returns the primary key of the row to the home object
6. The container creates an EJB object for the bean and populates
it with the primary key
7. The home object calls the ejbPostCreate() on the bean
8. The home object returns the remote reference to the EJB
object back to the client
9. Client now makes business calls to the bean instance.
No bean instance is associated with the EJB object
10. EJB object communicates to the container that a bean
instance is needed
11. The container allocates a bean instance from the pool
and associates it with the EJB object (ejbActivate() is called)
12. home object invokes the ejbLoad method on the bean to
tell it to load itself(BMP) or to tell it that it has just been
loaded (CMP)
13. the bean uses the primary key stored in the EJB object to load the approp row's data from the database
14. EJB object dispatches the client's business method call to the
bean
Hope this helps.

Reflection of remote interface

Hi. was wondering if you could use reflection to ennumerate the remote interface used by a java RMI server. I dont have anything specific in mind just a point at some documentation about this kind of reflection would be cool.......or any obsticles that would prevent me from doing so.
Thanks!

why do we have remote/home interface.What for? You'd just restrict the use of inheritance, without providing any additional implementation details or better design "semantics".

Remote Interface

Hey. I was wondering if there was a way to enumerate the remote interface used by an RMI server if you do not have the RMI Client. Ive been looking at reflection but from what ive seen it assumes you know what type of object you will be dealing with.

You can use reflection on the server or the stub to enumerate the interfaces it implements. You have to filter them so you only look at interfaces which extend java.rmi.Remote.

Using EJBObject as remote interface

Hello all,
I'm trying to make an ejb session available for web services. I see that we must create an interface similar to the EJBObject, but that simply extends Remote, to get the web service. So I tried to use the EJBObject (which extends Remote) directly in the wscompile to get the wsdl. Unfortunalety I get the following error message that I don't understand:
error: type cannot implement remote: javax.ejb.EJBHome
Can someone explain the problem ? And btw, I don't have any problem when I create a copy of my EJBHome and simply extends Remote instead of EJBHome. So why to I have to duplicate the same code in 2 separate classes ?
Thanks for the help
This works:
public interface OperatorGroupCommands extends Remote {
public void modify(OperatorGroup operatorGroup) throws RemoteException;
This doesn't work:
public interface OperatorGroupCommands extends javax.ejb.EJBObject {
public void modify(OperatorGroup operatorGroup) throws RemoteException;

I am having the same problem.
I am try to use web service security in the sun j2ee 1.4 application server. I noticed that web services built from servlets work just fine, but web services built from ejbs do not work so well.
I tried to deploy an ejb and the security stuff appears in the deploytool when I extend EJBObject. When I extend java.rmi.Remote, the stuff does not show up.
Did you ever solve this problem?

Remote Interface problem using Sun ONE App & web server

HI,
1) I am using an S'less SB. I have local & remote interfaces. I am using the sun one appserver7 & the sun ones's htttp server. By default it doesnt pick up the remote interfaces is it ? How do i make my remote interfaces work ? what are the changes required in config/xml ?
2) However i changed my client code (i.e my action class which is called by the struts action servlet ) to access the localhome rather than the remote home, but then i get java.lang.classcastexception.
pls help !
sanjay

Hi parsuram,
Thanks for the tip. After looking at the sample source code, I did finally figure out the solution - so I'll post it in case anyone else happens to be working with websphere studio has the same issue deploying on sun one.
To access local interface ejb, you must have the following
1. ejb-local-ref tag in the ejb-jar.xml like so underneath the <session> or <entity> tag of the bean which you plan to access the local ejb with.
<ejb-local-ref>
<ejb-ref-name>TestL</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
<local-home>memory.simple.TestLLocalHome</local-home>
<local>memory.tool.simple.TestLLocal</local>
<ejb-link>TestL</ejb-link>
</ejb-local-ref>
2. similar ejb-ref tag in sun-ejb-jar.xml
<ejb-ref>
<ejb-ref-name>TestL</ejb-ref-name>
<jndi-name>localejbs/module_memory.betaEJB/TestL68640023372300293</jndi-name>
</ejb-ref>
note: sun generates the <jndi-name> and overwrites whatever you put in that tag no matter what you put in there.
3. here is the code to access
Context initial = new InitialContext();
TestLLocalHome tlHome=(TestLLocalHome) Initial.lookup
("TestL");
//the string must match <ejb-ref-name> underneath <ejb-local-ref>
4. note that the jndi name for the local interface bean becomes irrelevant. only the <ejb-ref-name> in the ejb-jar and sun-ejb-jar matter. furthermore, both <ejb-ref-name> must be the same or you won't be able to deploy.
5. This is completely my fault for not checking the "proper" way to access local interfaces. in websphere, they let you get away without the ejb-ref tags and just use the string "local:/TestL"!

Adobe Reader XI (11.0.08) doesn't create thumbnail (bitmap) using Microsoft Interface IExtractImage -- Extract on Windows Server 2008 R2, when exe to generate thumbnail is launched from Windows service.

Adobe Reader XI (11.0.08) doesn't create thumbnail (bitmap) using Microsoft Interface IExtractImage --> Extract on Windows Server 2008 R2, when exe to generate thumbnail is launched from Windows service.
But if exe is launched as standalone, then interface IExtractImage --> Extract, gives Bitmap to generate thumbnail of PDF document.
Above problem occurs only for PDF documents, if we tried same with other software like CAD -CATIA it works without any problem.
Is there any security concerns form PDF side, which doesn't allow to generate Bitmaps, if exe to generate it is launched form Windows service.

It might be deliberate, Acrobat and Reader software is not intended to run in a service environment.

Configure webapp to use local or remote interface based on environment

Hi,
I have the following problem I am trying to solve (app server is Weblogic 10g by the way).
I have a webapp (war-project) and an ear project containing stateless session beans.
In our development environment I would like to deploy the war and ear separately, because that is easier for development (war-project can then be deployed as a directory, so changes to jsp's and such have immediate effect).
Deploying the war and ear separately means that the war-project can only call the session beans through their remote interfaces. For development this is not a problem.
In a production environment however we would like to package the war INSIDE the ear, so that the webapp can use the local interfaces to call the session beans, as this will improve performance.
So I am looking for a solution where I can configure the way beans are called. Local if the war is inside the ear, remote if the war is separate from the ear. I was thinking along the lines of packaging a properties file with the war that determines the mode (local or remote). Or maybe packaging a different deployment descriptor, if that is a possibility.
This is what I have so far:
Business Interface_
package be.cegeka.test.ejb3.service;
public interface TestService {
     public void doSomething();
Remote Interface_
package be.cegeka.test.ejb3.service;
public interface TestServiceRemote extends TestService {
Local Interface_
package be.cegeka.test.ejb3.service;
public interface TestServiceLocal extends TestService {
Bean implementation_
package be.cegeka.test.ejb3.service;
import javax.ejb.Local;
import javax.ejb.Remote;
import javax.ejb.Stateless;
@Stateless(mappedName="ejb/TestService")
@Local(TestServiceLocal.class)
@Remote(TestServiceRemote.class)
public class TestServiceBean implements TestService {
     @Override
     public void doSomething() {
          System.out.println("I'm doing something");
     @Override
     public void doSomethingLocal() {
          System.out.println("I'm doing something local");
JSF backing bean_
package be.cegeka.test.ui;
public class MyWebAppBackingBean {
     @EJB(mappedName="ejb/TestService", beanInterface=TestServiceRemote.class)
     private TestService testService;
     public String doSmth() {
          testService.doSomething();
          return "success";
}The part that I would like to be configurable is the "+beanInterface=TestServiceRemote.class+" part in the JSF backing bean. Depending on the environment (development vs. production), this should be "+beanInterface=TestServiceRemote.class+" for development and "+beanInterface=TestServiceLocal.class+" for production.
Is something like this possible?
I would like to avoid having to fill my web.xml with ejb-refs and having to do the JNDI-lookups myself if at all possible, to keep things as easy and clean as possible.
Any ideas are welcome!
Steven

So If they are supposed to be in the same JVM -
then
1. the cluster of 3 weblogic servers are three JVMs. So does that meanLOCAL INTERFACES CAN'T BE USED IN CLUSTERED ENVIORONMENT ?
Sure they can, but the calling component in an enterprise app will not call
an intance of the local bean on another node in the cluster. It will make a
by-reference call to the local component in the same EAR. Local interfaces
are not Remote, so they cannot be used with by-value RMI semantics.

Prob creating ABAP Proxy-Interface use external and interna msg definition

Hi,
I've created a service interface using external definition (message type for request and response), imported via WSDL file. However, while creating ABAP proxy in SPROXY, it gave the error message "Interface uses external and internal message definition". I searched through the forum, the questions were raised but no definite answer was found. Is it not possible to generate a proxy if there is any external definition used?
Details of the error message:
Message no. SPRX122
Diagnosis
In a message interface you can use messages from different sources:
Message types and fault message types edited in the Enterprise Services Repository
Messages imported into the Enterprise Services Repository (external definitions, RFC, IDoc)
In the current message interface, message types from different sources have been used. Since messages from these different sources must be handled differently during proxy generation, such a mixture of messages within a message interface is not possible.
System Response
The interface cannot be generated.
Procedure
Change the interface definition accordingly in the Enterprise Services Repository.
p/s: My external definition is actually derived from a ABAP FM web service. The reason why i used external definition is that i try to avoid the tedious steps of hard-coding all the data types for the request and response message types.
Any help would be highly appreciated.
- julius

Hi Arvind,
For technical reasons, proxy generation and the respective editors in the Integration Builder do not support the entire language range of XML schema and WSDL. For an overview of which language elements are supported, see the Excel spreadsheet in the SAP Service Marketplace at service.sap.com/xi ® Media Library ® Documentation: SAP XI 3.0 (SP11) u2013 Supported XML Schema and WSDL (EN).
I couldnt find the above document in the service market place. Any hint to find it?
Thanks.
