BPEL calling EJB 3.0 - EclipseLink error

I have an 11g BPEL process calling an EJB 3.0 method. It looks like the payload has been formatted correctly, but it is throwing an exception:
Exception [EclipseLink-70] (Eclipse Persistence Services - 2.0.2.v20100323-r6872): org.eclipse.persistence.exceptions.DescriptorException
Exception Description: A NullPointerException was thrown while extracting a value through the method [null] in the object [com.test.TestDataVO].

     ... 96 more
The EBJ WSDL was generated from the WSDL so if that was done correctly, the data schemas should be OK.
I really don't know how to go about debugging this. Any ideas?

Hi,
any annotation like this can be used only in "managed classes" like Session Beans, Servlets etc. Managed classes are those classes managed by the J2EE server. Managed here means, lifetime controlled by server.
You can find this in J2EE specification.

Getting error while calling ejb business methods from servlet

Hi
Iam getting error when i try to call a ejb method from servlet.Error is
"com.netscape.server.eb.UncheckedException: unchecked exception nested exception is:java.lang.NullPointerException".
I build the application and deployed it successfully.Iam using IAS 6.O with windows NT 4.0.
This is just a method which takes values from database and return as an array of bean to servlet.
Any help on this.Thanks Shank

Hi
I was using the session bean.Your suggestion helped me a lot.Perfect.
I debug my program and found that from ejbCreate()exception is getting.
I was getting the datasource object thro ejb create() initialisation.
Somehow the look up jndi which i mentioned was not interpretting from ejb-jar.xml ias-ejb-jar.xml and datasource ref .Due to this iam getting jndi Namenotfound exception which in turns to null pointer as datasource is getting null.
when i hardcoded in the ejb the the jndi name for datasource it is working fine.Bit worried all the existing ejbs working with the xml referenced datasource and jndi,but when i added a new ejb with same properties it is failing to get the jndi name.
Piece of code from ias-ejb-jar.xml
<resource-ref>
          <res-ref-name>myDataSource</res-ref-name>
          <jndi-name>jdbc/nb/myData</jndi-name>
</resource-ref>
Piece of code from ejb-jar.xml
<resource-ref>
          <res-ref-name>myDataSource</res-ref-name>
          <res-type>javax.sql.DataSource</res-type>
          <res-auth>Container</res-auth>

Thanks a lot meka

Oracle Service Bus, calling ejb on ormi protocol

Hi.
I'm trying to call an EJB on a Oracle Application server on the ormi protocol, but when i try to call it, I get this error:

I have my business service referencing a local jndi provider which in turn points to the remote server, on the ormi protocol.
Could I be missing some libraries?

I have my business service referencing a local jndi provider which in turn points to the remote server, on the ormi protocol.
Could I be missing some libraries?EJB transport doesn't support ORMI. Protocols supported by JNDI Provider resource are documented. Click help on you JNDI provider page.
supported protocols : http, https,t3, t3s, iiop,iiops.
Only BPEL transport supports ORMI (http://download.oracle.com/docs/cd/E13159_01/osb/docs10gr3/bpelpmtransport/transport.html)

Calling EJB with HTML via SERVLET

Hi,
I used a writen example that calls EJB from HTML via SERVLET. Example name is Bonus. The problem I have is that the HTML throw error while calling SERVLET. I dont figure out what seams to be a problem. Someone know?

anyone may help me,thank you in advance!
Regards peero

Hello,
I know the reason of the problem,that is the conflict from different
version of jdk.As we know weblogic6.1 run using jdk1.3.1.If I run tomcat
using jdk1.3.1,it work fine.But if change it jdk1.4.1,the error is always
same.
Anyway thank you!
then can you tell me if weblogic6.1 can run using jdk1.4.1? If true,how to
do?
Regards,
Peero

Hello,
Your WSDL looks fine, so this should not be your issue. I'd suggest
that you focus on the security framework.
Not much help,

Hello,
This is a curious stack trace and on the surface it looks like a
security issue. I'm not sure we can help you solve the axis problem,
but I would like to know from an interop perspective. Could you post
the wsdl for the service you are trying to call?
Thanks,

How to Call EJB from coldfusion

I need to call EJB that's created in JBoss from coldfusion.
I'm getting different errors depending on how I set the home object
and provider url.
If I prefix provider url with jnp://, then I get the
following error
The connection to the remote JNDI server on host jnp at port
1099 has failed (as have all backup hosts listed, if any) - please
verify that the server is running and the NamingService is
available
If I take the jnp out and keep just the ip address and port,
then i get the following error
null (no security manager: RMI class loader disabled).
So I'm not sure what the issue is and I haven't used this
feature before.
Here's my code

I tries to call custom EJBfrom custom component received
follwong error
ERROR [STDERR] javax.naming.CommunicationException [Root exception is java.lang.ClassNotFoundException:
No ClassLoaders found for: com.mycom.myapp.action.interfaces.pm.ejb.PmFacadeRemote
(no security manager: RMI class loader disabled)]
any idea?
Thanks

Calling EJB from an applet in 9iAS Release 2?

Hello!
In 9iAS Release 1 it is not so easy to call an EJB from an applet. First the applet needs special privileges and then the applet starts only once. The cause of problem is the implementation of ormi.
Will 9iAS Rel. 2 support Applets calling EJBs?

Jeff,
I am also trying to make an applet client for an EJB deployed to OC4J.
I modified the java2.policy file as you suggested, but when I tried to run my applet, I
got the following error:

I am using OC4J (stand-alone) version 9.0.2.0.0 on Solaris 7 and Microsoft Internet Explorer
5.0 with the java 1.3.1 plug-in.
Here is the applet code that I use to lookup the EJB home interface:
Properties props = new Properties();
props.put(Context.INITIAL_CONTEXT_FACTORY,"com.evermind.server.rmi.RMIInitialContextFactory");
props.put(Context.PROVIDER_URL,"ormi://host:6666/app");
props.put(Context.SECURITY_PRINCIPAL,"admin");
props.put(Context.SECURITY_CREDENTIALS,"password");
Context ctxt = new InitialContext(props);
Object homeObj = ctxt.lookup("my_bean");
MyBeanHome home = PortableRemoteObject.narrow(homeObj, MyBeanHome.class);
The HTML page with the <applet> tag is a static HTML page that is part of OC4J's default
web application. The applet class file is located in a subdirectory of the default-web-app

Calling EJB from Java Stored Procedures

Hi,
I am trying to call an Enterprise Java Bean from stored procedure. This stored procedure calls a java program. As long as it is a simple java program it works fine and loadjava.exe does not give any problem (neither compile-time nor run-time).
It is not working when I am trying to call EJB from it. It is giving compile-time error.
If anybody has implemented the same please suggest how to go forward.
thanks in advance,
Shashank Agarwal

I tried the same thing without any luck. I assume you are using OC4J for your EJB ...
The compiling issue may be because you don't have the classes in your EJB client jar loaded into the database. Once those classes are loaded, you should loadjava without any problem.
However, you won't be able to call the EJB server because the EJB client (your Java code in the DB) will need the OC4J environment (oc4j.jar). I have tried to load oc4j.jar into the DB as well, and that was a big mess and nothing worked. My DB is 8.1.7, maybe the new 9i have OC4J libs bundled?!?
I looked around and only found 2 alternatives:
1. Write a JSP page that acts like an EJB client, then use URLConnection in your DB java code to send params to the JSP for it to invlode the EJB
2. Replace the JSP with RMI code, and use RMI instead of URLConnection in your DB code to invloke the EJB client.
If you find any other solution, please share it here.
Good luck!

The error is thrown on when I do a post using "deliveryService.post("UserTaskSample", "4.0", "initiate", nm);"
An exception has occured : java.lang.Exception: Failed to create "ejb/collaxa/system/DeliveryBean" bean; exception reported is: "javax.naming.NamingException: Lookup error:

Hi,
Thanks for the reply since I am quite new to BPEl can you elaborate a bit on this .
What I did was
1. I created a Async BPEL process in JDeveloper and in the same project I put my servlet code and html part when I deploy it on the server and ascess it the welcome jsp is displayed when I click submit on wecome.jsp it forwards to servlet and there the error originates .
2 If instead I deploy the BPEl process seperately and the try to access the BPEL process using my JDeveloper java code I don't get any error it works fine.
3 I have included config and schema folders in source path . wf_client_config.xml,user-properties.xml and wf-config.xml is also present in the source folder.
4 Along with this the jars needed have been also added.
So when I deploy the BPEL process created in 1 above from Jdeveloper it creates a .ear in j2ee\home\applications and the deploys it .This .ear doesn't has any .class files .
I take bpelclasses.jar from the .jar which is created when I compile the project and put it in the j2ee\home\applib folder and made an entry for it in the server.xml file.After this it is able to get .class files.
If there is any alternate way to do the same thing kindly tell me .
Thanks
Pranay

Calling EJB from from a client app

Hi all,
I am trying to call an EJB component from portal. The example EJB I have taken is from SDN Bonus Calculator example - Application Server/Web Dynpro/Samples and Tutorials/Using EJBs (20)
I deployed the EAR file - no issue
I wrote the following code in a client app and trying to connect to the EJB remotely.
          try {
               java.util.Properties properties = new Properties();
               properties.put(Context.INITIAL_CONTEXT_FACTORY, "com.sap.engine.services.jndi.InitialContextFactoryImpl");
               properties.put(Context.PROVIDER_URL, "ux0800:55304");
               InitialContext ctx = new InitialContext(properties);
               //InitialContext ctx = new InitialContext();
               // get ejb home
               home =
                    (BonusCalculatorLocalHome) ctx.lookup(
                         "localejbs/MySessionBean");
               theCalculator = home.create();
          } catch (Exception namingException) {
               namingException.printStackTrace();
I get the following error
javax.naming.NoInitialContextException: Cannot instantiate class: com.sap.engine.services.jndi.InitialContextFactoryImpl [Root exception is java.lang.ClassNotFoundException: com.sap.engine.services.jndi.InitialContextFactoryImpl]

Hi Sabbir,
Following code works for me in calling EJB from normal java application. Did you added the jar files to your application?. see the required jar files in end of code.
Create simple java applcation do the following steps:
Give JNDI name to the EJB(HelloJNDI)->Add the HelloEJB to HelloEAR ->deploy
Proxy Program to call ejb:
import javax.naming.Context;
import javax.naming.InitialContext;
import com.sample.Hello;
import com.sample.HelloHome;
public class HelloTest {
     public static void main(String[] args) {
                   Hello remote = null;
                  try {
                    Context ctx = new InitialContext();
                    HelloHome home = (HelloHome) ctx.lookup("HelloJNDI");
                    remote = home.create();
                    String result = remote.hello();
                    System.out.print("Result:" + result);
                     } catch (Exception e) {
                            System.out.println("Exception:" + e.getLocalizedMessage());
1. Go To Run > Java Application ->New->select your project and select your main class(java program from which your going to call EJB)
2. Click next tab ->(x)=Arguments
paste the following code in VM Arguments
-Djava.naming.factory.initial=com.sap.engine.services.jndi.InitialContextFactoryImpl -Djava.naming.provider.url=localhost:50104
replace the server IP address with your server IP address where your ejbs are running.
Under Class path settings for the program put the following jar files.
You can search for them from net weaver soruce folders
or copy from D:\usr\sap\J2E\JC01\j2ee\j2eeclient
ejb20.jar
logging.jar
exception.jar
sapj2eeclient.jar
Add Corresponding ejb.jar
and RUN >>>
this makes testing of your client programs easier, you can find the error trace on which line and saves lot of time.

Calling EJB from applet

Hi friends,
I have a problem of caling EJB from applet.that too from browser.
Through dos prompt,I am able to set the classpath and then open the applet and then call the EJB.but thru browser i am encontering two problems,
First,The codebase of applet is not being set and i am unable to view the applet.
Second,my Initial Context Factory is not being found it is giving error as
Cannot instantiate class: com.evermind.server.rmi.RMIInitialContextFactory.I am using oracle app server Oc4j2.
can any one help me out.
i am able to get output thru dos prompt where i can set classpath

kyren,
he has used something called HTML ConvertersDepends on the version of the plug-in you are using.
(I'm sorry, but I couldn't find that detail in any of your posts!)
You have to use the (HTML) converter with java version 1.3 (for example), but you don't have to with java version 1.4.
thru my jbuilder version i am able to solve my
problem.
but thru browser,i am first of all not able to
display applet.That's because "JBuilder" uses the appletviewer to display the applet (and not a browser).
I Think for normal displaying applet we don't need of
signed or unsigned applet.when calling ejb we may
require.As Anupama has stated, the "codebase" attribute of the applet tag must be relative to the directory where the HTML file (containing the "applet" tag) is located. Where I work, we also use the "archive" attribute that tells the applet where to download the JAR files from. In order to lookup your ejb from your applet, you need (at least) the "oc4jclient.jar" file.
By the way, if you want your name to appear next to your posts (instead of your ID number), you need to update your profile. Click on the "Forum Settings" link at the top of the (Web) page.
Good Luck,
Avi.

Calling ejb remote method

SQLPLUS How to call ejb remote method in the sql plus.i am getting problem to intiallize the initial context.

hi chidambaresh,
you could have sent this to me directly.
the Enumeration si an interface and so the object we get during the runtime is basically an object of some implementation of this interface.
the Enumeration you get from HAshtable is actually Serializable.
but the Enumeration you actually get from Vector (this is actaully an inner class of Vector viz., Vector$1) is not serializable. that is what the error you are getting.
