Problem: call EJB by ejblocalhome

5.local home jndi name is:BaseInfoNotifyLocal.
6.I deploy the EJB by Jbuilder automatically.
Then I want to access the EJB throuth a servlet by the following code:
Context context = new InitialContext();
baseInfoNotifyLocalHome = (BaseInfoNotifyLocalHome)context.lookup("BaseInfoNotifyLocal");

Remote Debugging WLS

Has anyone set up a script (Windows) to run WLS in debug mode (-Xdebug)
according to the JPDA spec using JDK1.2.2? I want to step into EJB from
JBuilder.
Thanks, Jon

Hi.
I modified one of our standard start scripts for WL 4.5.1 to do this. The
server does start with this script, but I haven't used it to step into an
EJB from an IDE.
Hope this helps,

How to integrate the JBuilder5 and weblogic5.1 together?

Thousands of thanks to you!

hi,
i assume your question is to deploy ejbs from jbuilder 5 ito weblogic 5.1.0. to enable this, you must first have either Inprise app server 4.1 or borland app server 4.5. configure your jbuilder for one of these server first. this can be done in the enterprise setup menuitem under tools menu. then there will be a check box for enable integration. check this. then configure weblogic 5.1.0 a tab has been provided for this. configuration is simple. we have to tell the installation directory of weblogic. then restart jbuilder and gotcha it is integrated.
after creatting a project, alter the project properteis to have weblogic as the app server. build th jar file to create imple classes, stubs etc., noe run the project and the bean would be deployed.

How to deploy ejb in an Enterprise Environment using the jbuilder plugin

Hello:
I use Oracle9iAS Plug-in Release 2 (9.0.2) for Borland JBuilder 7 to deploy my ejb. But now, i would like to deploy my ejb to oc4j in an Enterprise Environment (not as standalone).
Does anybody know how can i do it? I noted that the plugin use admin.jar to deploy ejb, and I suppose it need to use dcmctl.
Thank you
Sergio

Sergio,
The current release of Borland JBuilder only allows you to deploy to standalone OC4J. If you want to deploy to Oracle9iAS (Enterprise OC4J), please try Oracle9i JDeveloper 9.0.3:
http://otn.oracle.com/software/products/jdev/content.html
JDeveloper 9.0.3 uses DCM to deploy to Oracle9iAS

Chen.

JBuilder plugin does not generate orion-ejb-jar.xml

Hello,
We are using JBuilder to code EJB's. I downloaded the OC4J plugins for JBuilder 5 and 6. Everything installed right but filling in the deployment descriptor does not automatically generate XML entries in the orion-ejb-jar.xml. I have to do this by hand.
Deploying to OC4J 1.0.2.2.1 succeeds and also running OC4J 1.0.2.2.1 in the debugger of JBuilder succeeds.
I would like to see an automatic process of filling in the right tags in the orion-ejb-jar.xml just as what happens in JDeveloper or in JBuilder for the ejb-inprise.xml.
Who is responsible for making the plugins?
The plugins are good but things must be better for working with JBuilder to Oracle 9iAS.
Last big very big point is the lack of good documentation.
Oracle, when you have good technology please tell me in good documentation how to use it otherwise how will I ever discover the good things. Maybe we are trowing things away because of not knowing.
The plugins are only for working with OC4J 1.0.2.2.x.
When will there be plugins voor OC4J version 2?
With regards,
Johan Borchers
VDA informatiebegheersing.

Here is the URL where you can download the JBuilder7 plugin for OC4J 903. It supports CMP and automatically generates orion-ejb-jar.xml, but the CMR mapping is supported from JBuilder8 and the corresponding plugin.

The manner that JBuilder names for ejb isn't seem canon

below is JBuilder auto produce
abstract public class LockerBean implements EntityBean{
public interface LockerHome extends javax.ejb.EJBLocalHome {
........} //"LockerHome" should correct "LockerLocalHome"
public interface LockerRemote extends javax.ejb.EJBObject {
...........}//"LockerRemote"should correct "Locker"
public interface LockerRemoteHome extends javax.ejb.EJBHome {
............}//"LockerRemoteHome"should correct "LockerHome"
but book says
remote interface names:<bean-name>Home
local interface:<bean-name>LocalHome
remote bean interface:<bean-name>
local bean interface<bean-name>Local
implementation classes:<bean-name>EJB
I have never seen <bean-name>Remote and <bean-name>RemoteHome
but JBuilder can compiler and run above class! why

From a compilation perspective,
It does not matter what you call the interfaces. You could call them larry, moe and curly for the different home interfaces.
All that matters is that they are indicated properly in the descriptors and used appropriately in the code.
Of course from a readability, usablility and maintainability perspective, use appropriate names.
What JBuilder does is a standard for JBuilder. (I think specifically the release of JBuilder you have)
It need not match what is there in your book.

Debugging session EJBs in WLS 6.1 with JBuilder 5

Hello,
I'm trying to debug my code by attaching my JBuilder 5 to a WLS 6.1 running on
my pc. This works fine up to the moment I try to debug code in a EJB session bean.
If I try to debug "step by step" I get a message:
Can not locate <my ejb>fquimtELOIml.java from project source/class path.
and when I try to evaluate the value of an object inside the EJB I get a message
"unable to evaluate"...
Does somebody have an idea what I did wrong?
Thanks,
Roland

Does somebody have an idea what I did wrong?Sure. Use System.out.println. It's ten times more
efficient that IDE debugging.

Fail to Deploy EJB to JServer in JDeveloper3.0

I had a trouble to deploy the EJBHotel example.
My env is Oracle8i in NT with JDeveloper3.0.
All IIOP & JDBC connection is fine. The user
had JAVAUSERPRIV and even JAVASYSPRIV.
The test under Published JServer Objects
has Public Read, Write and Execute Permission.
However I got the following message when I
deploy from JDeveloper (both JDK1.2 and JDK1.1).
Can someone give me direction to figure out
what privilege it needed?
Thank you very much.

Hi,
How did you uninstall the graphics drvier? From Devices manager or Programs and Features?
Please open Control Panel\All Control Panel Items\Programs and Features
And then, search for "NVIDIA Graphics Driver" and then select the "Change/Remove" button to begin the uninstall process.
Next, once the uninstall has completed, reboot Windows so that the other NVIDIA components can be removed as well.
If the issue still persists, since this driver that you recently installed caused problems with your PC, you can restore Windows back to an earlier point in time.

Help with EJB Arch: Synchronous front-end -- Asynchronous back-end

Hi folks, We are developing an application with the following characteristics: - users can invoke requests on our appl and they will expect a quick response - to obtain the information requested by the user, our application talks with Tibco using RV. This communication follows a pub/sub messaging paradigm and is asynchronous. - thus, we have a synchronous req/resp front-end and an asynch back-end.
We would like some advice as to the best way of architecting this application. Here is our approach. Please critic and suggest alternatives.
1. Consider an user who has requested something from our app. 2. The user will be using a JSP based front-end. (S)he submits the request on a form and a servlet is driven. 3. The servlet uses a session EJB and invokes one of its methods, which handles some business-specific logic. 4. The method in the session EJB then instantiates a helper class. 5. A method on our helper class is now driven. This method sends a message to Tibco and it provides a callback method in the helper class. 6. The method in the helper class blocks the thread - basically, it waits. 7. Meanwhile, Tibco does the processing and invokes the callback method (in the helper class) with the result. 8. In the callback method, the data sent by Tibco is stored in member variables of the helper class. 9. The callback method wakes up the blocking thread. 10. The method in step 6 wakes up and returns the information to the session EJB. 11. The session EJB returns the information to the invoking servlet. 12. The servlet provides the information back to the user.
The version of Tibco-RV that we are using is not JMS compliant.
We keep hearing that threads should be handled very carefully in an EJB container environment, so we would like to know if the way we are handling the thread in the helper class is okay. Could we remove the helper class and do the same thread-handling in the session EJB itself?
Can we use JMS in this solution even though our Tibco-RV does not support JMS?
Tools: Weblogic App Server 6.1, JBuilder 5.0.
Thanks for your advice and suggestions!

Let me start off by mentioning that Sonic MQ (an excellent JMS server) now provides a bridge for TIB/Rendezous. I am also wrestling with a simliar issue, something that requires threading at the servlet or ejb level, and have given some thought to using JMS. My concern was that JMS is an asynchronous process so it's model does not fit well with the synchronous front end. Technically I can see a few ways to implement it but architecturally I am not convinced that they are sound. You could send a message from the session bean to the TIB via SonicMQ and have a JMS message bean registered as a listener for messages from the TIB, again via SonicMQ. The JMS bean could update a static class or singleton which your session checks but you still have the issue of making the session bean wait on that event.
I'll do a bit more digging and see if there's a design pattern available for this situation.

EJB Dependencies in WebLogic

I have what I hope is a fairly straightforward question, but I can't seem to figure it out from the documentation.
I'm using Weblogic 6 and JBuilder. I'm trying to deploy an EJB. In the application folder of my Weblogic Server I put the .jar file for the EJB, and also a .jar file that contains a bunch of common classes needed by all the EJBs I'm working on. When the server starts up, the bean complains that it can't find the helper classes in the other .jar.
What do I need to do in order for the bean to be able to see and use classes in the other .jar file?

I am going from memory, but I believe that in WLS 6 that there is a \lib directory some where under the application deployment directory. This is where you need to add your helper .jar files.
