TO CALL AN EJB FROM A C++ CLIENT
Hi all,
I was trying out the build-an-EJB example in my Windows 2000 machine.
I was wondering whether instead of Client.java, I could have a Client.cpp?
Of course I thinks that it should be possible through Corba, but I would
like to hear what people here are sayimng....
Sample code or URLs containing sample code would be warmly appreciated.
Thanks in advance.

Check the docs on RMI-IIOP. You'll need a CORBA ORB.

How do I call an ejb from a java client?
I put ejb classes in a jar file along with java client code and deployed it on my OC4J server. Now I am trying to run the ejb by calling the client code on my OC4J server from the command line but I am not having success. Am I doing this the right way? Should I also deploy my client code? Should the client code also be in a directory on my OC4J server?
MikeHi. Here is a part of the code for a java client. In this particular case it is also an EJB but it is a Message Driven Bean.

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)
com.evermind.server.rmi.RMIClientConnection.waitForJndiResponse(RMIClientConnection.java:371)
com.evermind.server.rmi.RMIClientConnection.lookup(RMIClientConnection.java:179)
com.evermind.server.rmi.RMIClient.lookup(RMIClient.java:283)

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.

Looking up EJBs from a java client
While trying to migrate my application from standalone-oc4j
to Oracle Application Server 10g, I ran into the following problem.
My application has a stateless session bean. When trying to lookup the bean (from a java client), I get the following exception:
javax.naming.NamingException: Lookup error: javax.naming.AuthenticationException
Invalid username/password for UnifyoccEAR (ias_admin)
My code used the username/password I used to log into web-based console (which I used to deploy the application). The lookup code follows:
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
OracleJASLayer.INITIAL_CONTEXT_FACTORY);
env.put(Context.PROVIDER_URL, "ormi://localhost:3201/UnifyoccEAR");
env.put(Context.SECURITY_AUTHENTICATION, "simple");
env.put(Context.SECURITY_PRINCIPAL, username);
env.put(Context.SECURITY_CREDENTIALS, password);
Context ctx = new InitialContext(env);
Object obj = ctx.lookup("unify/nxj/controlCenters/occ/ControlCenterEJB");
On a whim, I tried the old SCOTT/TIGER username/password and got the following
exception:
javax.naming.NoPermissionException: Not allowed to look up unify/nxj/controlCenters/occ/ControlCenterEJB,
check the namespace-access tag setting in orion-application.xml for details
So evidently, SCOTT/TIGER is in the security database used by the app (but isn't
authorized) while the ias_admin user is not in the security database.
I have the following questions:
1. In the default configuration, is there a username/password I can use to
lookup EJB homes in the jndi namespace of an OC4J instance? If so, what
is it?
2. Where is the security database? I tried looking in the web-based console
to find how to configure security and could not figure it out. I did find
the Security page for the application, but when I tried to add a user,
it had no effect. Furthermore, this page did not show a user entry for
SCOTT; hence, it doesn't seem that OC4J is actually using the information
on this page. This is strange because the path to this page is:
Farm > Application Server: ias_admin.lab10.sac.unify.com > OC4J: home > Application: UnifyoccEAR > Security
I then went to the Security page for the default application and found
that it did have a SCOTT user. So I added a new user and tried to run
my java client. This resulted in the javax.naming.AuthenticationException
described above (I was expected the NoPermissionException encounted when
using SCOTT/TIGER). Next, I used the Security page for the default application
to change the password for SCOTT and reran my java client using SCOTT/TIGER.
This time I was expecting an AuthenticationException exception, but got the
NoPermission exception. Therefore, it seems that OC4J isn't using this
security data either.
Hunting in the console (again) for the security database, I stumble accross
the Infrasturcture page and see an Identity Management section and see that
it is configure to use an Oracle Internet Directory server. Using
<ORACLE_HOME>/bin/oidadmin, I connect to the directory server and look
for the SCOTT user. I don't find it, so I believe that this can't be the
security database either.
3. Finally, how do I configure the OC4J instance such that it will allow
anonymous users to lookup my EJB from a java client?
Please help a confused and frustrated user.Looking at your example, it looks like you are using a J2EE client container or some properties file to specify the JNDI environment used to create the initial context (for you use the no-arg constructor to InitialContext). Since our application needs to the ability to dynamically connect to ejb's running on different Java application servers (e.g., WebLogic, WebSphere, JBoss), such an approach will not work. Instead we must do it the old-fashioned way and pass the jdni connection info to the InitialContext constructor.
In any event, our problem isn't how to write the connection code, it is how to test it. Specifically, we can't figure out a valid username/password that will allow us to look up the home. Nor can we figure out how to configure security for the oc4j instance. -

Error when calling BPEL process from web service client
I have created three projects here ,there're no problem when testing Composite Application(SynchronousSampleApplication) by test case inside this project.
When I create a Java Application(SynchronousSampleApp),inside this project I've created a web service client from file WSDL of BPEL. After that, In Main class, I call an operation from web service client.But have the following error:

Calling an EJB from jsp - ServletException
I am unable to call an EJB from jsp, unless I put the actuall classes of
the EJB into the classpath. Is this the right way to do it?
The exception is:
Servlet failed with ServletException
javax.servlet.ServletException: Servlet class: 'jsp_servlet._result'
could not be loaded - the requested class wasn't found in the
classpath:

Did you package your JSPs in a WAR and your EJBs in a JAR and package the
WAR and JAR in an EAR? That is how to do it in 6.0. Works well.

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 VHi 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();
Here is my Stack Trace...

Calling web-service from non-SAP client
Hi,
Could anyone here help me with the code with which we can call the non-SAP service in java from a java client.
I have the wsdl and service deployed on the server.
Regards,
ManojHi Eduardo,
We are trying to consume a non-SAP webservice (https based) which uses a certificate issued by the non-SAP web service provider for authentication.
We tried consuming the web service using the Web Dynpro Java's Adaptive WebService Model method. We configured the Logical Destinations with X.509 client certificate authentication and have added the certificate to the WebServicesSecurity keystore.
However, when we run the application, we get the 'Peer certificate rejected by ChainVerifier' error.
Could you guide us on how to resolve the same ? If possible would you also provide the step-by-step details of how to create the EJB application that you did to achine this ?
Any help is greatly appreciated.
Thanks.

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=0Your 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 an EJB from Java Mappings in PI 7.1
In my operation mapping, I am using a Java class which in turn invokes an EJB using JNDI lookup.
When I execute the code, the class is successfully finding the EJB using JNDI, but invoking it I am getting a java.lang.NoClassDefFoundError.
If, I add the class it cannot find to the jar containing the Java mapping class, I get a java.lang.ClassCastException.
Has anyone been able to call a custom EJB from with a Java Mapping class?
Any help appreciated.

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.Abbreviated error trace

HELP!!! How I can call to EJB from another EJB??
I have two EJBs, for each EJB I have a jar, how I can call to EJB jar to another???
I have tried the following, in the first EJB I have import the second EJB jar and call it with context, lookup, PortableRemoteObject etc.. but the instruction lookup not find the second EJB reference.
The name in the lookup instruction is the JNDI name of the second EJB but not find a reference to it.
Please help me!!! Thanks!!

Here as you can see, EJB1LogBean(session bean) is calling a second EJB, EJB2LogBean (entity bean). TestVal is a sample value object passed. It is plain java class and can vary from app to app and it has got nothing to do with ejbs.
"java:comp/env/ejb" is a J2EE standard and while getting a home interface, you have to append the home interface class name to "java:comp/env/ejb". Here I am passing "java:comp/env/ejb/EJB2LogHome" and "1" to getHome method, whose job is to get a reference to a home interface. getHome method is a local method. "1" is passed just to give a flexibility to getHome method as you can have more ejbs to invoked. In that case, you can go on adding different case statements for 2, 3 etc.
The only thing you have to keep in mind is that your deployment descriptor for EJB1LogBean will contain the entires for both the beans i.e. for EJB1LogBean and EJB2LogBean. This is because EJB2LogBean is wrapped by EJB1LogBean.
Hope this helps.
Please let me know if you need anything more.
