Create EJB and call it from ABAP

Hi all,
I have written a stand-alone-Java application, which should be converted into a web application, which has no gui.
This application should be triggered by a abap-program.
Following questions, do I have to write a servlet and a ejb or is it possible to call the ejb directly from the abap-program?
What do I have to do make an outbound call from abap?
Thank you for your support.
Kind regards, Patrick.

Hi.
You can call the EJB directly from Abap. XI uses this functionality extensively.
Follow these steps:
1) Deply the bean on the java stack.
2) You now need to setup a RFC destination in the JCO RFC Provider service in the j2ee visual adminstrator. Point the Repository section to the application server you want to run the Abap reort on. When you do this the j2ee engine will register itself as a possible RFC destination on this application server.You can choose your own program id...
3) You then need to goto tran sm59 on the app server where the Abap report is going to run and setup a connection of tcp type to the j2ee machine. Specify the same program id you used in step in the technical settings.
4) Then just use the bean name when you do the rfc call in the abap report.
Hope this helps if U have not done it yet.

Is it possible to call a class method using pattern in ABAP editor.

Hi,
Is it possible to call a class method using pattern in ABAP editor.
Thank U for Ur time.
Cheers,
Sam

Yes,
Click patterns.
Then choose Abap objects patterns.
Click on the Tick
It will give a new screen
Here Give the name of the class first.
Then the object (instance of the calss)
And finally the method ..
it will give you the pattern

Calling Java API from ABAP using JCo (Part 2)

Hello,
This is an additional question to thread Calling Java API from ABAP using JCo
Has anyone managed to get the input parameter value
input.getString("REQUTEXT")
that is being passed from ABAP?
If yes, what kind of setting you need to do? Because when I execute, it has no value.
Thus, the below ECHOTEXT parameter returns blank value:
output.setValue(input.getString("REQUTEXT"),"ECHOTEXT");
When I debug by printing the below line, the input XML is indeed without value:
System.out.println(input.toXML());
Anybody knows how to pass input variable from ABAP to JAVA using JCo?
rgs,
hiroshi

Hallo Hiroshi,
as far as I can see, you are doing it the right way. The problem might be that the ABAP program does not fill in this parameter because something went wrong in the SAP System.
Have you tried setting a breakpoint (an HTTP session - remote breakpoint) and tried checking step by step if the value is being processed and put into the REQUTEXT field?
Bye,

Calling BRM from UDF using JNDI lookup with @EJB annotation

Hi Experts
I am trying to implement a UDF to invoke my BRM Rules set via JNDI Lookup instead of a SOAP Channel lookup.
I have had a look at the following links/docs:
Calling BRM from UDF using Public API
http://www.gleanster.com/system/resources/W1siZiIsIjIwMTIvMDgvMDcvMjAvNDcvNTAvNDMvVGhpbmdzX1lvdV9TaG91bGRfS25vd19hYm91dF9TQVBfTmV0V2VhdmVyX0JSTS5wZGYiXV0/Things%20You%20Should%20Know%20about%20SAP%20NetWeaver%20BRM.pdf
For item 1 above, the example looks really good, but it doesnt explain how I get access to the following required imports from my UDF:
import com.sap.brms.qrules.ejb.*;
import com.sap.brms.qrules.engine.AbstractProject;
import com.sap.brms.qrules.engine.RuleEngine;
import com.sap.brms.qrules.engine.RulesetContext;
import javax.ejb.EJB;
The second document is really good as well, but I could not figure out how to get it to work from my UDF.
So, can anyone help me to understand specifically what is required to get this to work?
Is is possible to invoke the rule set from my UDF?
How do I give my UDF access to all the required jars/imports?
I have manage to create a new DC (Development Component) with a public part and this enables me to get my code to compile on my local PC but I am not able to activate it due to the server not having access to the same java packages as my local copy.
Any help would be greatly appreciated.

You resolve the dependency by importing the required jars with using the dependency tab for the mapping program.
As stipulated before, I have managed to resolve the dependency issue but I have now getting the same error as in the forum: Calling BRM from UDF using Public API
The specific error is:
com.sap.engine.services.cross.PortableRemoteObjectContainer.narrow(PortableRemoteObjectContainer.java:238)
Has anyome manage to get invoke a BRM Ruleset using JNDI?

I need a clarification : Can I use EJBs instead of helper classes for better performance and less network traffic?

My application was designed based on MVC Architecture. But I made some changes to HMV base on my requirements. Servlet invoke helper classes, helper class uses EJBs to communicate with the database. Jsps also uses EJBs to backtrack the results.
I have two EJBs(Stateless), one Servlet, nearly 70 helperclasses, and nearly 800 jsps. Servlet acts as Controler and all database transactions done through EJBs only. Helper classes are having business logic. Based on the request relevant helper classed is invoked by the Servlet, and all database transactions are done through EJBs. Session scope is 'Page' only.
Now I am planning to use EJBs(for business logic) instead on Helper Classes. But before going to do that I need some clarification regarding Network traffic and for better usage of Container resources.
Please suggest me which method (is Helper classes or Using EJBs) is perferable
1) to get better performance and.
2) for less network traffic
3) for better container resource utilization
I thought if I use EJBs, then the network traffic will increase. Because every time it make a remote call to EJBs.
Please give detailed explanation.
thank you,
sudheer

Please suggest me which method (is Helper classes or Using EJBs) is perferable :
1) to get better performance
EJB's have quite a lot of overhead associated with them to support transactions and remoteability. A non-EJB helper class will almost always outperform an EJB. Often considerably. If you plan on making your 70 helper classes EJB's you should expect to see a dramatic decrease in maximum throughput.
2) for less network traffic
There should be no difference. Both architectures will probably make the exact same JDBC calls from the RDBMS's perspective. And since the EJB's and JSP's are co-located there won't be any other additional overhead there either. (You are co-locating your JSP's and EJB's, aren't you?)
3) for better container resource utilization
Again, the EJB version will consume a lot more container resources.

Performing database operations using EJB 3.0

I need to create a session bean that will perform operations on backend database. I am new to EJB 3.0 and need a gentle guidance to the solution
This is what I believe is suppose to be done
1. Create stateless bean interface marking operations.
2. Create bean implementation for above
3. Init stage will require me to connect to the Oracle database. Now am confused how will it get the connection details? Is there a way to extract the url username and password using resource bendle which can be accessed from within bean implementation?
4. Bean method will perform update, read oprations
5. Predestroy will close the connection
6. A client will simply call this ejb with some input parameter(s)
Please let me know if am doing anything wrong here

If you use EJB technology for which it is designed, the container (server) will manage the transaction (and also the connections to the database) for you, so no creation or cleanup of connections on your part. I advise you to read into JPA which is designed to be used in conjunction with EJB tech. The books Enterprise Javabeans 3.0 and Pro EJB 3: the Java Persistence API may help you a lot.

Problem with "package-info.java" using EJB 3.0 and OC4J

Hi all.
I already posted this question on JDeveloper forum, but didn't get any answer,
so I'll try posting here.
Anyway, I'm new both to JDeveloper and J2EE,
so I'm trying out examples for EJB 3.0, and I got stuck at "Use Security Annotations with EJB 3.0"
(http://www.oracle.com/technology/tech/java/oc4j/ejb3/howtos-ejb3/howtoejb30security/doc/how-to-ejb30-security-ejb.html).
Example code is working perfectly, if one builds it using Ant, but I'm importing all examples into JDeveloper (or at least I'm trying to :))
JDeveloper can't build file "package-info.java" containing following code:
@javax.annotation.security.SecurityRoles(roleNames={"superuser", "user"})
package oracle.ejb30;I'm getting following output in "Compiler - Log" window:
Error(2,1): 'class', 'interface', or 'enum' expected.
Help much appreciated...
platform used:
Windows XP SP2
JDeveloper Studio (Version 10.1.3, Build 3412)
JDK 1.5_06
OC4J 10.1.3 developer preview 4 (standalone version)

Since you're using EJBs, you can use JTA and can skip the getTransaction() calls. If you want to use getTransaction().begin() and commit(), then make sure that your EntityManager is resource-local. The configuration for this is in persistence.xml. Set a transaction-type of RESOURCE_LOCAL rather than JTA.

HOW TO CALL A WEB SERVICE OR EJB FROM BPEL

HI
i want to call java web service or ejb from my bpel process. how can i do this.
i am using oracle soa10.1.3.1.0 and jdeveloper 10.1.3.1.0 and oracle database xe 10g.
thanks in advance K ROY

You could deploy your EJB or Java under a web service into your OC4J, after that, you invoke a partnerlink from BPEL to the destination of wsdl will do. Also don't forget to add in your XSD schema as well.
Thanks,
Jyno
