Call RFC from EJB code

Hi,
I have a scenario where I need to write an EJB from where I need to execute a JCO call to an RFC. This RFC takes an XString as input (this is the input file) and returns a XString from which an XML needs to be generated.
Can anyone suggest how to go about this?
Thanks,
Shiladitya

JRA is the way to go....

ClassCastException calling EJB from EJB (diff EARs) Urgent please help !!

Hi,
I�m trying to call a Remote EJB ( in jdev BBEAN.prj ) from another EJB (in jdev ABEAN.prj) located in a different EAR.
In JDEVELOPER (oc4j 9.0.3) I also considered BBEAN as a libreary which is included in the ABEAN project.
So that the ABEAN JAR contains the class definition for the Home and remote interface.
From the ABEAN bean I call this code:
DO ()
private static Context getInitialContext() throws NamingException
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.evermind.server.rmi.RMIInitialContextFactory");
env.put(Context.SECURITY_PRINCIPAL, "admin");
env.put(Context.SECURITY_CREDENTIALS, "manager");
env.put(Context.PROVIDER_URL, "ormi://GSARNO-1/BBean");
return new InitialContext(env);
BBeanHome BBeanHome = (BBeanHome)PortableRemoteObject.narrow(context.lookup("BBean"), BBeanHome.class);
BBean bBean;
��..
After having deployed both projects I then run a client (Calling the Do function).
Doing so I keep receiving the following error when calling narrow.
java.lang.ClassCastException

Can anyone help ?
What should I do to call remote e/o local interfaces located on different EARs ?
I�m using OC4J 9.0.3

Hi Giuseppe,
If both EAR files are in the same OC4J instance you do not have to use RMIInitialContextFactory to invoke the EJB. You have to do the following:
In OC4J
1) Make the BBEAN as the parent for ABEAN application defined in the server.xml as follows:
application name="ABEAN" path="../applications/abean.ear" parent="BBEAN" auto-start="true" />
2)
You can define ejb-ref or ejb-local-ref in the deployment descriptor of your application
3) You can use the default InitialContext to lookup your EJB as if both EJBs are in the same application

Those were a couple of posts I found, that seemed similar, but not really. I appreciate the experienced help and your thoughts!

Calling non ejb from ejb using jndi lookup

Is it possible to call a non ejb java object from an ejb using a jndi lookup?
For example, we have a java class where main registers itself with our application server (JBoss 3.0.1). We have a test client that can use jndi to look up the object, but we can't get an ejb inside the application server to use the object.
Are we trying to do the impossible? If my question is not clear, please let me know so I can try to clarify.
Thanks

JNDI uses factories to create objects.
It's possible that JBoss has a Bean Factory which you can use to create your instance.
Tomcat has a Bean factory in its JNDI implementation. I use it just as you have indicated.
The JBoss documenation may help?

125: VALUE_HOLDER_INSTANTIATION_MISMATCH while calling toplink from ejb

Hi Folks
I am calling registerNewObject from from a stateless session ejb.
The object i wanted to persist is as below
A--> Collection B ---
each item in collection B is mapped as one to one mapping to object C.
When I try to persist it, i get following excecption:
Exception [TOPLINK-125] (OracleAS TopLink - 10g (9.0.4.9) (Build 060118)): oracle.toplink.exceptions.DescriptorException
Exception Description: The mapping for the attribute [RPGOperRole] uses indirection, and so must be initialized to a new ValueHolder. Currently the value is: [null].
anything missing that should be done when calling from ejb

You need to initialize your variable RPGOperRole in your class to a new ValueHolder(), either in its constructor or variable definition.
i.e.
public B() {
this.RPGOperRole = new ValueHolder();
or,
private ValueHolderInterface RPGOperRole = new ValueHolder();

Help needed in EJB - to call AS from EJB a Session Bean

Hi All ,
I have been strictly told not to use Web Services as all the applications are on the same server
actually I have to make an EJB invocation to an Application Service from the CAF layer from a Session Bean of another EJB Project(Not a CAF Service).
the CAF layer has 5 parts metadata , permissions , dictionary , ear and ejbmodule.
I added the ejbModule to the Build Path of the calling EJB Session Bean. And so I was able to access the operations of the Application Service which in turn accesses a BAPI(The Appl Service operation returns a String).
But while executing I got the exception java.lang.RuntimeException: java.lang.NoClassDefFoundError
My method :
Normally from a Dynamic Web Project acting as a client to an EJB Session bean, I was able to get access to EJB Local Interface by using
private ConverterLocal converterBean = null;
public void jspInit() {
    try {
     InitialContext ic = new InitialContext();
     converterBean = (ConverterLocal)
     ic.lookup("java:comp/env/Converter");
    } catch (Exception ex) {
         System.out.println("Couldn't create converter bean."+
       ex.getMessage());
BigDecimal dollarAmount = converterBean.euroToDollar(value);
So I created a JNDI field in ejb-j2ee-engine.xml
enterprise-beans>
        <enterprise-bean>
     <ejb-name>com.sap*******.bapi_company_getlist.BAPI_COMPANY_GETLIST</ejb-name>
               <jndi-name>COMPANY</jndi-name>
            </enterprise-bean>
</enterprise-beans>
And from my Session Bean , I tried to access it using the code in already existing Bean which was working fine
BAPI_COMPANY_GETLISTBeanImpl bean = new BAPI_COMPANY_GETLISTBeanImpl();
          try {
               InitialContext ctx = new InitialContext();
               bean = (BAPI_COMPANY_GETLISTBeanImpl)ctx.lookup("COMPANY");
          } catch (NamingException e) {
               System.out.println("Converter Bean can't be created");
               String send = bean.returnDetails();
And I tried to print the String , but I got the above error
I have a doubt :
1) How do I specify the JNDI name ie in the ejb-j2ee-engine.xml file , what should I add as the name of the ejb
is this sufficient , or are there more steps ??

Hi Ekaterina,
I have the document to access my Bean from another Bean.
I could access my Bean from a standalone Java class with this code
Properties props = new Properties();
          props.put(Context.INITIAL_CONTEXT_FACTORY,"com.sap.engine.services.jndi.InitialContextFactoryImpl");
          props.put(Context.PROVIDER_URL,"hostname:port");
          try{
               Context ctx = new InitialContext(props);
               Object o = ctx.lookup("sap.com/TestEAR/REMOTE/TestBean/com.@#$.TestRemote");
               TestRemote testRem = (TestRemote)javax.rmi.PortableRemoteObject.narrow(o, TestRemote.class);
               String msg = testRem.getMessage();
               System.out.println(msg);
And in this document there is a way shown to access a bean from another Bean.
   http://help.sap.com/saphelp_nw04/helpdata/en/13/c8633e0084e946e10000000a114084/frameset.htm
If your client is another enterprise bean, declare the EJB reference in the ejb-jar.xml.
-For more information, see Declaring EJB References.
But the problem is that in EJB 3.0 , I can't see the ejb-jar.xml file .
So how should I have a Bean as a client to another Bean, I am not that familiar with Annotations.

Call RFC from EJB using SSO

Can anyone point me in the right direction on the best practice for calling an RFC using SSO from an EJB?
When using the local interface for the EJB, the only solution I see is to pass the authenticated IUser instance from the portal component to the EJB business method through the method signature.
I am guessing that there is a better way to get access to an authenticated user in the EJB container.

Thanks for the reply.
Actually I was able to solve the problem last night. To get SSO to work in my local EJBs I created an RFC destination in the destination service using the visual administrator. I then used the destination service at runtime to pull the system definition from the J2EE system definitions store instead of the portal system landscape definitions and my connection object was created as expected.
Here is the code to create the connection in my EJB business method:
//get the user
IUser user = UMFactory.getUserFactory().getUserByUniqueName(this.myContext.getCallerPrincipal().getName());
// get the destination service
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sapportals.portal.prt.registry.PortalRegistryFactory");
InitialContext context = new InitialContext(env);
IDestinationsService destinationsService =
(IDestinationsService) context.lookup(IDestinationsService.SERVICE_JNDI_NAME);
// define a destination filter to restrict to the RFC defined destinations
DestinationFilter destinationFilter1 =
new DestinationFilter(DestinationFilter.SOURCE_J2EE_DESTINATION_SERVICE, DestinationFilter.TYPE_SAP);
// get a user specific connection
IConnection connection = destinationsService.getConnection(user, "ECC", destinationFilter1);

[b]How connect to EJB from java webstart[/b] ?

Hi,
I'm a newcomer to J2EE, I'd like to build J2EEE app
first of all,I've developed simple EJB components and jSwing client to call method from EJB. All in the same project.
Client programe has method
private static Context getInitialContext() throws NamingException {
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.evermind.server.rmi.RMIInitialContextFactory");
env.put(Context.SECURITY_PRINCIPAL, "admin");
env.put(Context.SECURITY_CREDENTIALS, "welcome");
env.put(Context.PROVIDER_URL, "ormi://10.145.100.2:23891/current-workspace-app");
return new InitialContext(env);
When I run client app it work well, I follow in Jdev905 to deploy to java webstart
1. Create .jar file (Item JAR file - Simple archive)
2. Create Java web start(JNLP) files
after that, I have .jar,.html,.jnlp file
3. running project(use embedded OC4J server)
4. running .html file
first, java webstart download code then run but nothing
happen. I think that It may be some wrong in JNDI look up.
I try my best, It's taken me a week but I still do'nt understand.
! Please help show how to go through that or how to deploy using java web start. We intend to develop rich client.
thanks a lots!

Challenge: call local ejb from remote ejb on weblogic 9.2

Hi ALL,
How do I call to local ejb from remote ejb object. The jar file is deployed on weblogic server 9.2, if you want get it http://geocities.yahoo.com.br/lindembe/BEAProject.jar and the source code are http://geocities.yahoo.com.br/lindembe/BEAProject.zip. It is a sample app with two ejb that works so good on JBOSS, JOnAS, but BEA Weblogic.....
The complete problem you watch http://forum.java.sun.com/thread.jspa?threadID=768718&messageID=4387570#4387570
or
http://forums.bea.com/bea/message.jspa?messageID=600043148&tstart=0

Your code in SigemFacadeBean should just do:
InitialContext ctx = new InitialContext();
when you lookup the local EJB. (This will work on all app servers. There's no need to put an app-server specific intial context factory in your code.)
Also, you can remove the jndi-name setting for the local ejb from your weblogic-ejb-jar.xml. jndi-name is only applied to remote ejbs.

Calling a newly deployed EJB from an EJB gives a NoSuchMethod Exception if the jar of the newly deployed ejb is not in the classpath

Hi ,
I have an EJB A which is already deployed when the server starts. A second ejb
B is deployed at a later time.
EJB A calls methods in EJB B. I use reflection in EJB A to call methods in EJB
B.
I get a NoSuchMethodException when I call the create method in the Home object
of EJB B. If I add the ejb jar file to the classpath before the server starts
then it is able to resolve the method.
The problem is the EJBs which are called from EJB A is not known before the server
is started. New EJBs can be deployed at runtime and EJB A should be able call
the methods in newly deployed EJB's.
I also use the URLClassLoader to load all the classes in the jar file of the newly
deployed EJB in EJB A and it still gives a NoSuchMethodException because it cannot
resolve the stub class.
My error log is shown below.
This is an urgent issue.
Thanks

Hi,
I am attaching a test case. This test case actually demonstrates a security bug.
Unzip the file and modify the StartWeblogic.cmd in domainA to not refer to the
SampleRemoteEJB.jar in the classpath. If u run the test client under the client
dir u will see a NoSuchMethodException.
The reason is it is not able to load the dynamically generated stub file.
Initially I had the getMethod and it didn't work. You might have to modify the
files to suit ur env. The easier way is to run th edomain wizard and create 2
domains. Run the servers in development mode and place the jars under the applications
dir
Thanks

Why is it giving you a NoSuchMethodException instead of a

Can you post the code from SampleConctorEJB.java, line 181?
Try changing your call to getDeclaredMethod() to getMethod().
getDeclaredMethod() searches only the class you called it on, whereas
getMethod() traverses to the superclasses and interfaces. You onlyneed
getDeclaredMethod() when you're accessing a nonpublic method.
Not sure if this will help, but it's worth a shot.

How to Call one EJB from another

Hi all
I am trying to call one EJB in one system from another EJB residing on diferent system...
Both are Stateless session beans ...
I can't use No-args Intialcontext() as i need to specify the Ip address of other system to be looked up.....
So i am using properties Dorg.omg.CORBA.ORBInitlalHost....
But its not looking up..Its telling not bound...But i called it from standalone client remotely...
Am i wrong..?
I hope I am in right path....
I hope ill get reply as fast as possible...
Gopal V

Hi ken Thanks for replying....
Ya i packed it as a jar (using Export tool in Eclipse3.2)....
I am using SUN AS 9.....
I packed bean1 and bean2 as two different jars in the same domain...
Here is my code...
Bean1:
@Stateless(mappedName="ejb/Second")
public class SecondIMPL implements SecondRemote {
     public FirstRemote obj;
     public String connect() {
          try{
               InitialContext ctx= new InitialContext();
               FirstRemote obj =(FirstRemote)ctx.lookup("ejb/First");
               System.out.println("Client :"+obj.bMethod());
          }catch(Exception e){
               e.printStackTrace();
          return "Check server Log";
}Bean2 :
@Stateless(mappedName="ejb/First")
public class FirstIMPL implements FirstRemote {
     public String bMethod() {
          return "From First Bean";
Client:
public static void main(String[] args) {
          try{
               InitialContext ctx= new InitialContext();
               SecondRemote obj =(SecondRemote)ctx.lookup("ejb/Second");
               System.out.println("Client :"+obj.connect());

Error while calling PI webservice from EJB

Hi Experts,
We are getting exception while calling PI webservice from EJB which is deployed in CE 7.2. Earlier we used to call the same webservice but from different PI system at that it worked fine. Now we have changed the consumer proxies required in CE and tried to call from CE and it is throwing error. We have checked usernames and passwords that we are using to call the service and that is working fine. PI team tested from their side and li is also fine. We have also restarted the CE system but invain. Can somebody help on this. The below is the trace that we got.

Hi Pradeep,
this looks like if the server is not reachable. Have you checked if both server are able to communicate? Maybe firewall rules block the request.

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
