Issue calling an EJB

Hello everybody.
I have the following scenario:
I have an enterprise application with two EJB modules.
I am trying to call an EJB located at a package, from a class in the other package. In netbeans I am using the wizard "Call an enterprise bean" and it creates a lookup method which is supposed to return the interface.
When I use this method to initialize the interface field, I am getting an java.lang.NullPointerException.
A thing I do have is that the source package at the two modules is named the same. Could it cause the error?
Any hint about that?
Thanks in advance for your help.
Sergio Guti�rrez

Hi Serkola.
I did try renaming the package and still get the NullPointerException.
I am not sure how to invocate the EJB from the first package. Can I use EJB annotation, or do I have to execute a conventional naming lookup?
Regards.

Can I call an EJB from the database?

Hi,
I've just spent the last few days attempting to call an EJB from a stored procedure in a 10g database (and still haven't succeeded).
Now having spent hours searching the web (and this forum) for any successful examples (so far I have found none) I thought I'd add a message to see if there is anybody out there who has done this successfully. If so can you please provide me some details on how to do this?
Alternatively, I'd appreciate any input on how I can overcome my current hurdle in attempting to do this myself.
Here's how far I've got in my attempt:
I have a simple stateless session bean deployed to both Oracle 10gAS (a standalone OC4J container in 10.1.3) and to Weblogic 9. I have a client java class that calls a method on this bean and displays some ouput if successful. This all works from a standalone JVM (version 1.4) on both Weblogic and 10gAS.
I then tried to load the required libraries for Weblogic onto the database (namely the Weblogic.jar file). This resulted in the addition of some 32,000 odd objects of which 30,000 odd could not be resolved. I figured a lot of these may be down to JVM version issues (I believe that Weblogic 9 uses the 1.5 JRE) so I decided to put the Weblogic test on the back burner for now and just use the Oracle app server.
The tests with the Oracle app server looked promising. I only needed a handful of libraries to be loaded onto the database and all the relevant classes required for my test client had resolved (including the initial context factory required to do the jndi lookup of the bean). After granting all the permissions I believed I needed I'd got to the point where I could do a jndi lookup of the EJB; but when I tried to create an instance of the beans remote interface I got the following error:
java.security.AccessControlException: the Permission (java.lang.RuntimePermission getClassLoader) has not been granted to ProtectionDomain (file:generated/by/proxy <no certificates>)

Has anybody come across this before? If so can they help?
If not has anybody out there actually managed to call an EJB method (without going via an RMI server/Servlet/or any other proxy).
Any help in this matter would be greatfully appreciated.
Cheers,
Anand.

Sure, here's the code. It's what JDev generates automatically but I have seperated some things into several diffrent lines so I could experiment easier.
final Context context = getInitialContext();
Object o=context.lookup( "SessionEJB4" );
Object l= PortableRemoteObject.narrow( o, SessionEJB4Home.class );
final SessionEJB4Home sessionEJB4Home = (SessionEJB4Home)l;
SessionEJB4 sessionEJB4 = sessionEJB4Home.create();
String ret=( sessionEJB4.hello( ) );
As I mentioned, for this I have used EJB2.1 bean, because I had same problems with EJB3.0, so I tried earlier versions of Java to make sure that is not the problem.
hello() method just returns string "hello".
Of course, this works in standalone client that is not loaded into database.
Now, I loaded all the jars mentioned in this thread, using loadjava options -v -resolve, and I loaded client using options -v -resolve -genmissing . Select query on user objects in database shows that client class and relevant classes are all valid.
Then I created stub and ran it. First it stopped throwing exception ORA-29532: Java call terminated by uncought Java exception: Java.lang.NoClassDefFoundError.
Method I try to run returns String value which is hello message if it works fine, else it prints the part of the stack trace. In this case, after p[revious error, When I try to run it again, i get return from the method :
Lookup error: java.lang.NoClassDefFoundError; nested exception is:
     java.lang.NoClassDefFoundError
com.evermind.server.rmi.RMICall.throwRecordedException(RMICall.java:89)

javax.naming.InitialContext.lookup(InitialContext.java:347)
simpleejbproject.EJB4Client.hello(EJB4Client.java:35)
Of course, regular version of the client I run frokm command line works fine.
So I'm kind of a stuck here. I followed all directions, tried it on oracle 9 and oracle 10 DB, the problems remain the same. Am I missing something here?
Thanks
Just to add, getInitialContext()
    private static Context getInitialContext() throws NamingException {
        Hashtable env = new Hashtable();
        // Oracle Application Server 10g connection details
        env.put( Context.INITIAL_CONTEXT_FACTORY, "oracle.j2ee.rmi.RMIInitialContextFactory" );
        env.put( Context.SECURITY_PRINCIPAL, "oc4jadmin" );
        env.put( Context.SECURITY_CREDENTIALS, "manager1" );
        env.put(Context.PROVIDER_URL, "opmn:ormi://mserv:4005:home/TestEjb4");
        return new InitialContext( env );
It goes withouth any exceptions.

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...

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());
          }catch(Exception e){
               e.printStackTrace();

JCo 3.0 - RFC call from EJB with SSO

Hello,
I am trying to call abap using JCo 3.0 from EJB (NW CE 1.0). I have configured destination on server with authentication method to use SAP Logon tickets. But when I call my EJB method that looks like this:
JCoDestination dest=JCoDestinationManager.getDestination("RFCCallTest");
JCoRepository repo=dest.getRepository();
JCoFunction f= repo.getFunction("ZMG_RET_NAME");
JCoParameterList in=f.getImportParameterList();
in.setValue(0, "param1");
f.execute(dest);
I get an exception when executing the first line of code:
Message: Exception occurred during lookup of RFC Destination RFCCallTest: No SAP logon ticket found
Category: /System/Security
Location:com.sap.security.core.server.destinations.provider.DestinationsProviderFrame.getDestinationProperties()
When I change the destination authentication method to Technical user it works well.
SSo between the servers works.
This scenarion also works when I use older JCo implementation (2.x)

Hi Bill,
I too faced the same problem for quite some time on SP9. I thought it was the adapter problem that persisted ...but it was not !!
After importing the RFC structure into XI, if the name of the imported RFC program is renamed/changed on R/3 side, then you will get the same error "lookup of binding via CPA-cache failed for AdapterType RFC, AdapterN."
So make sure that RFC program name on the R/3 side was not changed/renamed after you have imported the RFC structure into XI.
If the RFC program name had changed, make sure you reimport the RFC structure to avoid this problem.
Regards,
Sridhar

when I search this problem in java.sun.com,an article announce that it is a bug that
JNDI not support multi-threads call,and it is fixed is JDK1.4 beta. The link is:
http://developer.java.sun.com/developer/bugParade/bugs/4307751.html
It seems that weblogic's JNDI is not support multi-thread call. what can i do?

Try adding the following code before instantiating your initial context:
Thread.currentThread().setContextClassLoader( ClassLoader.getSystemClassLoader()
This fixed the problem for me.

a bug that
JNDI not support multi-threads call,and it is fixed is JDK1.4 beta. The

It seems that weblogic's JNDI is not support multi-thread call. what can

Calling an EJB application in webdynpro

Dear SDN's,
I am trying to call an EJB application from a webdynpro application and is succeded in storing values to database via Java Bean Model.
I want to retrieve all records from table via EJB and all the records should be displayed in Webdynpro Table UI element.
How can we do it?
The problem here is, how to return a set of records to webdynpro from EJB via a javabean.
I am not clear in using Collection Framework! i.e, which collection class i have to use to store the retrieved records.
Your help will be appreciated.
Regards,
Sireesha.B

Hi Sireesha,
Instead of adding resultset, create a EMP cinstance and add it.
Ex : Consider you have created a EMP class
class EMP
String empname;
int id;
public void setEmpname(String name);
public String getEmpname();
Now
ResultSet rs=statement.executeQuery(select * from emp);
Vector v=new Vector();
while(rs.next)
Emp e=new EMP()l
e.setEmpName(rs.getString(0));
e.setID(rs.getInt(1)));
v.add(emp);
Iterator i=v.iterator();
while(i.hasNext())
Emp e1=(EMP)i.next()l
System.out.println(e1.getempName());
System.out.println(e1.getID);

Calling an EJB throws an UNKNOWN exception

Hi EJB experts!
I`m trying to call an EJB on OAS from Java application running within a JDeveloper. After several calls of remote method the application invokes the remote method again but exception
java.rmi.UnexpectedException: CORBA: org.omg.CORBA.UNKNOWN: get a timeout exception; nested exception is:
org.omg.CORBA.UNKNOWN: get a timeout
is thown.
class Context {
public java.sql.Connection conn;
public EJBRemote logger;
Reference to a remote EJB is stored in class Context. Instance of Context is shared among three other objects. Strange thing is that whether the exception is thrown or not depends on the number of method calls on objects accessing the Context. In any case remote method completes successfuly. Do you have an idea what to do with this exception?
Thanks for any advice. David Mrva

How to call the EJB methods from servlet/jsp

Hello ,
i have write one ejb signOn having the method validateUser(username,password).i can able to call this function from client.java class.i want to know whether i can call this function from servlet.if yes then where to write that servlet and web.xml file.
At present i m using weblogic server 8.1and i create directory call c:\ejb\demo and put the ejb files(home ,remote,ejb class ,client.java) then i have created .jar file and put in application file.
Now i want to create a servlet for that i have to create a new directory and put the servlet,web.xml,weblogin-web.xml file and then create one .war file and put in application directory or do some thing extra.Please help me.
Thanks In Advance

I think this might not be the most appropriate forum for your question. You might try a forum about ejb, or weblogic, or jndi.

Calling an EJB deployed in OC4J from a Java Stored Procedure

Hi all,
Well, I've been trying to figure this out for a bit now and haven't come up with a solution.
I have a Java Stored Procedure in a 9i database and would like to call an EJB deployed in the OC4J Container but DO NOT want to load the various Orion JAR files into the database.
I get hung up on the JNDI piece.
Has anyone figured out how to do this?
Got some code?
Thanks!

Doug,
This is not possible in Oracle9i Release1. in the upcoming Oracle9i DB R2, we will support loading a client-side jars of oc4j (oc4jclient.jar) in the database and call-out EJBs in 9iAS
Please look at this thread Re: Compile procedures for a detailed dicussion on this topic.

Security with Web Service calling some EJBs

Hi everybody,
I have implemented some web services residing in a war file deployed on my Tomcat. The web services module is a client to some EJBs deployed on my JBoss. I need to log the user in my realm on each WS request and log the user out before the WS response.
I have implemented security on web applications with JBoss and used JAAS realms succesfully but what do I do in this case with Web Services? I mean the requests are stateless. If I use the org.jboss.security.ClientLoginModule
won't this override the credentials of another user who is already logged in the realm?
I have also implemented a standalone application which spawns a thread for each user request and I am wondering about the same thing. This application is a service listening for some kind of messages; on a message the application should log the user in the realm before calling an EJB and log the user after the request is completed. So it's more or less the same situation as above.
Is this possible? I mean logging many users in the same realm in one non-web application?
Any ideas?
Thank you in advance!!!
thoism

requests are stateless, just as are requests to webapps.
Which is hardly surprising as a web services stack is typically implemented as a web application.
If you could log in only a single user at the same time to an EJB application, it would be rather pointless to have the application as a distributed multiuser system :)
What you might check is whether you're allowed to log in the same user several times, if I remember correctly this can be limited in the EJB module deployment descriptors.

Hi Siarhei,
thank's for your answers , i'll explain the scenario , i think i copied wrong the code that i have ,
i have two EAR's applications , i want to call one EJB from the other EJB in other EAR , the call have to be remote , my code is the next :
ctx = new InitialContext();
Object obj = ctx.lookup("sap.com/TestEJB_ear/TestEJBBean");
TestEJBHome home = (TestEJBHome) PortableRemoteObject.narrow(obj,TestEJBHome.class);
TestEJB servicio= home.create();
i've confugured the ejb-xml.jar adding
<ejb-ref>
<ejb-ref-name>ejb/TestEJBBean</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
<home>com.innovativesystems.onl.TestEJBHome</home>
<remote>com.innovativesystems.onl.TestEJB</remote>
</ejb-ref>
I've configured the ejb-j2ee-jar.xml adding
<ejb-ref>
<ejb-ref-name>ejb/TestEJBBean</ejb-ref-name>
<jndi-name>sap.com/TestEJB_ear/TestEJBBean</jndi-name>
</ejb-ref>
I've configured the application-j2ee-engine.xml adding a hard reference
<reference
reference-type="hard">
<reference-target
provider-name="sap.com"

</reference>
with all this configuration still send me the message java.lang.classcast ,
something is missing???? ,

How do youi call an EJB from a composite app

I created a simple composite application, called testserve.
Here is the entire body of the implementation class, testserveBeanImpl.java
package com.sap.demo.testserve.modeled.appsrv.testserve;
import com.sap.demo.*;
@com.sap.caf.dt.CAFWebService(name="testserve")
@javax.jws.soap.SOAPBinding(style=javax.jws.soap.SOAPBinding.Style.RPC, use=javax.jws.soap.SOAPBinding.Use.LITERAL)
@javax.jws.WebService(name="testserve", serviceName="testserve", portName="testservePort", targetNamespace="http://www.sap.com/caf/demo.sap.com/testserve/modeled", wsdlLocation="META-INF/wsdl/testserve.wsdl")
@javax.ejb.Stateless(name = "com.sap.demo.testserve.modeled.appsrv.testserve.testserve")
@javax.ejb.Local(value = { com.sap.demo.testserve.modeled.appsrv.testserve.testserveServiceLocal.class })
@javax.interceptor.Interceptors(value = { com.sap.caf.rt.interceptors.LogInterceptor.class })
public class testserveBeanImpl extends
          com.sap.demo.testserve.modeled.appsrv.testserve.testserveBean {
                //these two lines are used to inject an EJB which is packaged in the EAR
     @javax.ejb.EJB (beanName="com.sap.demo.TestbeanBean")
               private com.sap.demo.TestbeanBean theTestBean;
     @com.sap.caf.dt.CAFOperation(name = "serviceTest1")
     @javax.jws.WebMethod(exclude=false, operationName="serviceTest1")
     @javax.jws.WebResult(name="outputParameter1")
     public java.lang.Integer serviceTest1() {
                               //test1() just writes to console, simple test to test EJB connectivity
          theTestBean.test1();
          return 1;
There is a second ejb project called testejb which contains the stateless session bean TestbeanBean.
The code compiles fine as typed above.
However, when deployed, I get the following exception, which I will post in a reply, since this post is too long. I am sure that I neglected to
set up something so that the testserve service can find the EJB TestbeanBean at runtime, but I need some
guidance. I have searched the help for a couple days and have not found anything useful. Is there a step by step
explanation for configuring this? To be clear, I want a web service created in the Composition Application perspective
to be able to call an EJB in an EJB project. I don't want to create a web service out of the EJB (TestbeanBean) for performance reasons. Thanks.
The service works fine when the 3 lines relating to TestbeanBean are removed.
