Generating EJB Automatically

Guys,
I have a doubt regarding EJBGen and Workshop/WebLogic Server.
I would like to generate automatically some EJBs.
I have a DataSource working that points to a DataBase SQL Server. There are some Tables there that I would like to produce some EJBs.
How can I do that?
Is it possible to do by Eclipse Workshop? Or is it possible to do with a script? Maybe and ant script using ejbgen?
How to do it?
Thanks,

Hi Daniel,
Unfortunately this is Not Possible in WebLogic/Workshop... to genarate the EJB2.x Style Entitybeans from an Existing DataBase. But it is Possible in EJB3...But for that u need to a Persistence API and tools like (KODO/TopLink/Hibernate)..Then we have an Option from Workshop to Create a Persistence Unit mapped to the database.
But There is a Feature available in Sun Application Server along with "NetBeans" Utility to Generate CMP2.x Style of Bean from from an existing database in fraction of Seconds. U can Generate The Entity Beans from NetBeans and then With a Small modifications in the Deployment Descriptors you can Deploy those entities in WebLogic.
Thanks

How to generate PDF automatically.

Hello,
I am generating INVOICES using REPORTS 6i.
After created the PDF format, I send to the customer by email.
I would like to do this process automatically.
So how can I generate PDF automatically?
There is any pl/sql functionality available to generated PDF automatically.If so how can I generate similar like report 6i format and symbols (Logo).
Pls give me some ideas.
Thanks,Kannan.K

Kannan,
a scheduler is part of Reports, with which you can automate to generate Reports. There's a Queue Manager with your installation. But for this you need Application Server based Reporting - not Client/Server.
Also it's possible to send an PDF-Report as an EMail-attachment directly. Starting with 9i there's also an PL/SQL-API available (Event-based Reporting).

Using JarSettings to generate EJB client jar, but supported classes missed

Appreciated for any comments in advance.
I am using @jarSetting to generate EJB client jar file from workshop 9.2. The remote method of EJB has one input parameter that is defined as an interface. The interface is included in client jar, but the implementation of this interface is not.
Please advise how I can add the implementation of this interface to client jar?
Best Regards,
James

Hi James,
I believe the algorithm for creating the client jar is to simply inspect the EJB interfaces using reflection and to include all user defined classes and exceptions that are referenced by the interfaces. In your case, it sounds like a class is not being included because it is not directly referenced by one of the EJB interfaces.
I think the client jar creation algorithm can be described as "best effort" and unfortunately, it does not always end up including all classes needed by the client. I would recommend you add the additional classes manually using the jar tool.

Anyone know of a tool for auto generate EJB from DB

Does anyone know of a tool that connects to a DB and auto generates EJBs from the table schema, either CMP or BMP. Perhaps allowing you some control over choosing the table, pk, etc.

Generating .gg automatically?

Hi,
just wondering if the interface file .gg can be generated automatically by parsing the c file or header. I realize you can change function names and massage types in the .gg, but if you don't need any of that, a tool like swig would be able to generate .gg automatically? I'd like to know what considerations are inovolved around spec'ing the interface automatically or manually.
Thank you.

Generate EJB using Eclipse.

How do i write the EJB application in Eclipse? I mean which all classes do I have to write?

So if i write 1 class the others will get created
automatically in XDOClets?I think you have to write a bit more than one class, but all the interfaces will be generated yes. Look at tutorials, they are prettyeasy and straight forward.

Closing the report generating engine automatically

how can i close the report generating engine after displaying a report automatically ie when closing the report window the report generating engine also need to be closed. now i have to manually close the report background window also and it becomes annoying to users . i am using the rdf files and not rep files.

There is a parameter ORACLE_SHUTDOWN. Set it to YES.
When you have large, complex reports, the Reports Background engine sometimes eats lots of memory and leads to GPF. If you have lots of GPF when running a report, you should use this parameter.

Thanks lots, Slava .
U r right, now instead of using javac, I'm using jikes, which is good for
all jdk.The problem is that your Java runtime may be still 1.5, so you may get other
strange errors. I don't think you will need 1.5 for a while, at least to develop
apps under weblogic. You may want to review your environment settings.
HTH.

Hi John,
Make sure that you are using JDK 1.4.2, not 1.5.x. You may know your javaversion by
running this command:
java -version
Hope this helps.

Generating report automatically.....

I have a reuirement from the users where in they have number of reports generally time bound, say previous week.
The solution they are looking out is to have these reports are generated automatically and sent via email to a specific group mailbox.
Can we achieve the above functionality in Business warehouse, if so how.
Note: I think we need to create a report manually by providing the date range and generating the report and exporting from SAP.
I am not sure whether there is any procedure of this the same automatically.
your inputs will be appreciated.

Urgent: Need to know a Program name which generates Numbers automatically

Hi Peers,
We all know that there are 2 kinds of Numbering :
1. Internal Numbering
2. External Numbering
For eg: When we create an Sales Order a new SO number is generated automatically which is called Internal number generation.
There is an Object which generates this number I would like to know that Program. If any Idea please let me know.
The reason why I need is , Thru a transaction when we are create entries for an Z table , the number should be generated automatically.
Points will be suitably rewarded.
Thanks a Lot.

Weblogic7/examples/clustering/ejb Automatic failover for idempotent methods ?

This one should be easy since it is from the examples folder of bea 7 about
          clustering.
          Ref : \bea7\weblogic007\samples\server\src\examples\cluster\ejb
          I am referring to the cluster example provided with the weblogic server 7.0
          on windows 2000.
          I deployed Admin server and 2 managed server as described in document.
          Everything works fine as shown by the example. I get load balancing and
          failover both. Too Good.
          Client.java is using the while loop to manage the failover. So on exception
          it will go thru the loop again.
          I understand from the documentation that the stateless session EJB will
          provide the automatic failover for Idempotent stateless bean
          Case Failover Idempotent : ( Automatic )
          If methods are written in such a way that repeated calls to the same method
          do not cause duplicate updates, the method is said to be "idempotent." For
          idempotent methods, WebLogic Server provides the
          stateless-bean-methods-are-idempotent deployment property. If you set this
          property to "true" in weblogic-ejb-jar.xml, WebLogic Server assumes that the
          method is idempotent and will provide failover services for the EJB method,
          even if a failure occurs during a method call.
          Now I made 2 changes to the code.
          1 . I added as follows to the weblogic-ejb-jar.xml of teller stateless EJB
          <stateless-clustering>
          <stateless-bean-is-clusterable>true</stateless-bean-is-clusterable>
          <stateless-bean-load-algorithm>random</stateless-bean-load-algorithm>
          <stateless-bean-methods-are-idempotent>true</stateless-bean-methods-are-idem
          potent>
          </stateless-clustering>
          So I should get the automatic failover .............
          2. Also I added the break statement in the catch on line around 230 in
          Client .java
          catch (RemoteException re) {
          System.out.println(" Error: " + re);
          // Replace teller, in case that's the problem
          teller = null;
          invoke = false;
          break;
          So that the client program does not loop again and again.
          Now I compile and restart all my three servers and redeploy application (
          just to be sure )
          I start my client and I get a automatic load balancing between the server
          which makes me happy.
          But Failover ....?
          I kill one of the managed application server in cluster at any particular
          test fail point.
          I expect the exception to be taken care automatically by error/failover
          handler in the home/remote stub
          But the client program fails and terminates.
          1. What is wrong with the code ?
          2. Does the automatic failover with the indempotent methods also has to be
          taken care by coding the similar while loop for stateless ejb ?
          Your help will be appreciated ASAP.
          Let me know if you need any thing more from my system. But I am sure this
          will be very easy as it is from the sample code.........
          Thanks


Sorry I meant to send this to the ejb newsgroup.

I m now wondering how generate the EJB client jar (Stubs and interfaces )to access my EJB module from anywhere.
Any Idea?

I found the answer.
