JDev 10.1.3: Problem deploying a session bean to embedded OC4J

JDeveloper 10.1.3, TopLink, OC4J, WinXP, java 1.4.2_05.
I used TopLink to create a set of Java objects from a DB Schema, then created a simple Session Bean to read some of the objects. Everything compiles fine.
JAVA_HOME points to the JDK (not JRE) and CLASSPATH is empty (undefined).
When I try to Run my session bean in the jdeveloper embedded oc4j, I get this message. Thanks in advance for your help.

Does the EJBdeploy in some other server?

A simple problem with sateful Session beans

Hi,
I have a really novice problem with stateful session bean in Java EE 5.
I have written a simple session bean which has a counter inside it and every time a client call this bean it must increment the count value and return it back.
I have also created a simple servlet to call this session bean.
Everything seemed fine I opened a firefox window and tried to load the page, the counter incremented from 1 to 3 for the 3 times that I reloaded the page then I opened an IE window (which I think is actually a new client) but the page counter started from 4 not 1 for the new client and it means that the new client has access to the old client session bean.
Am I missing anything here???
Isn�t it the way that a stateful session bean must react?
This is my stateful session bean source.
package test;
import javax.ejb.Stateful;
@Stateful
public class SecondSessionBean implements SecondSessionRemote
private int cnt;
/** Creates a new instance of SecondSessionBean */
public SecondSessionBean ()
cnt=1;
public int getCnt()
return cnt++;
And this is my simple client site servlet
package rezaServlets;
import java.io.*;
import java.net.*;
import javax.ejb.EJB;
import javax.servlet.*;
import javax.servlet.http.*;
import test.SecondSessionRemote;
public class main extends HttpServlet
@EJB
private SecondSessionRemote secondSessionBean;
protected void processRequest (HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
response.setContentType ("text/html;charset=UTF-8");
PrintWriter out = response.getWriter ();
out.println("<html>");
out.println("<head>");
out.println("<title>Servlet main</title>");
out.println("</head>");
out.println("<body>");
out.println("<h1>Our count is " + Integer.toString (secondSessionBean.getCnt ()) + "</h1>");
out.println("</body>");
out.println("</html>");
out.close ();
protected void doGet (HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
processRequest (request, response);
protected void doPost (HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
processRequest (request, response);
}

You are injecting a reference to a stateful session bean to an instance variable in the servlet. This bean instance is shared by all servlet request, and that's why you are seeing this odd behavior.
You can use type-leve injection for the stateful bean, and then lookup the bean inside your request-processing method. You may also save this bean ref in HttpSession.
@EJB(name="ejb/foo", beanName="SecondBean", beanInterface="com.foo.foo.SecondBeanRemote")
public MyServlet extends HttpServlet {
ic.lookup("java:comp/env/ejb/foo");
}

Can I deploy the session bean to 9i in the JDeveloper3.2

dear ONT
My JDeveloper3.2 can't find the method to deploy the session bean to 9i.
sk

I'm not sure that's entirely correct.
Personally I run both EJBs and servlets/JSP in OC4J. OC4J has all the 'web' features of IAS, including full SSL support.
From a speed perspective, running the EJBs and web components in the same container will give you a huge benefit.
Also I'm not sure what you mean by "you can't deploy EJBs into OC4J yet" - I do it daily? ;)

Mail Session configuration with embedded oc4j in jdeveloper 10g 10.1.3.1

Hello all:
I'd tried to use javamail in a j2ee application. I´d defined an resource reference with the EJB Module Editor but when i run the application it throws:
java.lang.InstantiationException: Error initializing ejb-modules: No Mail Session configured for the resource MailSession
How can i configure a Mail Session with the embedded oc4j of jdeveloper 10g 10.1.3.1?
Thanks a lot.

Hi,
You need to add following configuration in $ORACLE_HOME/j2ee/home/config/application.xml & restart your OC4J :-
<mail-session location="EMailSession" smtp-host="mail.cdsc.com"> <property name="mail.transport.protocol" value="smtp"/> <property name="mail.debug" value="true"/> </mail-session>Regards,

Im having what appears to be the same exact problem (Im getting a NPE and same error message). Did this get resolved? Im using xdoclet as well ... Here are the respective deployment descriptors that are getting created via xdoclet ...

I ran into the EXACT same problem described by Tracy, and I assembled my .ear file manually.
According the error message, it would appear that the server is looking for the EJB remote interface in the ../temp/__session_bean_rpc directory when it is trying to generate its session bean wrapper class. As Tracy notes, when the file Hello.class is copied into the directory, the problem goes away. Furthermore, once the wrapper class has been generated, Hello.class is no longer needed and can be deleted from the directory.
Better still, I found a way to deploy the web services web module and make the error go away. I created the ejbws.war file with a copy of the remote interface Hello.class in the WEB-INF/classes directory. This makes the class available when the wrapper class is generated.
The WebServicesAssembler tool doesn't copy the EJB remote interfaces into the .war web module, which would appear to be
necessary.
Hope this helps.

Problem Calling Remote Session Bean Method

Need help. I am trying to call a method in a remote stateless session bean in an EJB in my web application from a stateless session bean in a different EJB in the web application. I am getting a run-time error that says,
"java.lang.NoClassDefFoundError: dtpitb.common.sb.reports.CommonReportsHome"
ref = ctx.lookup( jndiName );
// Cast to Local Home Interface using RMI-IIOP
commonReportsHome = (CommonReportsHome)
PortableRemoteObject.narrow(ref, CommonReportsHome.class);
If while in a session bean of an EJB, I want to call a public method in the session bean of a totally different EJB, is there something in particular I am missing. I can make the call from the web application code. I can make a remote call from this session bean to itself in the exact same fashion. I just can't call a session bean in another EJB. All thoughts are welcome.
Thanks,
Pete

Thanks for replying. That could very well be the case I suppose. I'm using JBuilder and WebLogic, and JBuilder pretty much does all of the deployment descriptor code for me. However, maybe this is something I need to incorporate manually.
One EJB is in the same project as the web application code. The other EJB (common_ejb) is in another project. The calling session bean is in the project with the web app, and the remote session bean method that I'm targeting is in the common EJB session bean. Both EJBs are included in the web app's WEB-INF\lib dir and in the war file.
So theoretically, this isn't an unconventional practice I assume?
Thanks,
Pete

Problem when calling session bean from main.

Hi everyone
I get the following error when calling a session bean from main(String args[]).
Sep 3, 2008 9:11:13 AM com.sun.enterprise.appclient.MainWithModuleSupport <init>
WARNING: ACC003: Application threw an exception.

Here is my code beneath.
I'm using netbeans and glassfish application server.
Everything is in the same project, called DatabaseTest, I also have deployed the application before running the client.
I'm running the client as follows, right click on the DatabaseTest-app-client and select run.
The client:
package databasetest;
import com.test.UsersFacadeRemote;
import javax.ejb.EJB;
import com.test.Users;
public class Main {
    @EJB
    private static UsersFacadeRemote usersFacade;
    public static void main(String[] args) {
        Users users = new Users(12, 34);
        usersFacade.create(users);
}The remote facade I'm calling:
package com.test;
import java.util.List;
import javax.ejb.Remote;
@Remote
public interface UsersFacadeRemote {
    void create(Users users);
    void edit(Users users);
    void remove(Users users);
    Users find(Object id);

}The stateless bean:

        return em.find(com.test.Users.class, id);
    public List<Users> findAll() {
        return em.createQuery("select object(o) from Users as o").getResultList();
}

looks like you're banging your head against the same brick wall as [I have done|http://forums.sun.com/thread.jspa?forumID=13&threadID=5317110] and [others have in the past|http://forums.sun.com/thread.jspa?forumID=136&threadID=5259913] if that's any consolation.
Funny thing is, mine did actually work in the debugger but not when running!
Strange thing that.
I did initially interest someone from the developers but they couldn't really help, ended up saying : try instantiating your beans the EJB 2.1 way and see where that gets you. Yes that works but they promised us "hey no more dopey xml deployment descriptors just some cool annotations" didn't they?
I've got the feeling were' missing something really obvious!

I have got problem to create Session Bean

Hi
I am new in j2ee. I have installed the eclipse 3.1, j2sdk1.4.2_07 and tomcat 5.0. I have created a ejb with a session bean and it gives me a error the program doesn't find the class javax.ejb.SessionBean. My question is Can this error happen because I don't have installed J2EE 1.4 SDK and Sun Java System Application Server Platform Edition 8.1?
thank you

Hi
I have tried to put the classpath with j2ee in eclipse but it happens the same. it doesn't find the package javax.ejb.SessionBean.
I am going to explain i have done from the beginning. Maybe I am wrong in something. I think which is that.
I have create a proyect with Dynamic Web Proyect after i create a proyect with ejbModule. I attempt to create a file with session bean. In last proyect acceded to Run->Run here i select Apache Tomcat and Tomcat v5.0 Server _ localhost and i select the classpath in "bootstrap entries" i insert the file j2ee.jar. And I' ve got the same error.
is it fine? I am bored trying to find the problem.
thanks in advanced

How to deploy a session bean in Weblogic 9.2

Hi,
Can anyone please point me to the procedure of deploying session bean on weblogic 9.2. My operating system is Fedora 5. Please let me know the steps as i am very new to EJB.
Regards,
Sanjeev

I looked for this information in ServletConfig, in ServletContext, in JVMID
ServletConfig or ServletContext do not have anything (at least I do not see anything),
The newsgroups recommend the following code
public static String getLocalUrlString()
String urlString;
JVMID jvmid = JVMID.localID();
urlString = jvmid.getHostAddress();
weblogic.rjvm.Protocol proto
=weblogic.rjvm.Protocol.getDefaultProtocol();
int port = jvmid.getPort(proto);
return urlString + ISoapConstants.SCHEME_DELIMITER + port;
I also tried
weblogic.rjvm.Protocol does not exist in current version, and I did not get any real information inside JVMID
Also tried JVMID.localID().ports(), which returns null
System.getProperty("weblogic.system.bindAddr"); or weblogic.system.listenPort property,
getProperty returns null
Tried also another approach from the newsgroups - JwsContext.
/** @common:context */
JwsContext context;
String myPort = context.getService().getURL().getPort();
String myUrl = context.getService().getURL().toString();
context is null
None of them worked.
Do you have any other ideas?
All those ideas I found in the newsgroups were to the previos version(s) of weblogic - up to 8.1. I have not found anything specific to 9.2

Problem calling a session bean (EJB 3.0)

Hello,
I'm new to netbeans and J2EE. I'm using NetBeans 5.5 Beta 2 and sun application server 9 pe.
I created a new enterprise application and i'm trying to access a Session Bean (Remote and Stateless)
from the app-client (outside the main class).
This is the loockup method that was generated by the IDE (Enterprise Resources > Call enterprise bean):
private ejb.SessionBeanDoenteRemote lookupSessionBeanDoenteBean() {
try {
javax.naming.Context c = new javax.naming.InitialContext();
return (ejb.SessionBeanDoenteRemote) c.lookup("java:comp/env/ejb/SessionBeanDoenteBean");
catch(javax.naming.NamingException ne) {
java.util.logging.Logger.getLogger(getClass().getName()).log(java.util.logging.Level.SEVERE,"exception caught" ,ne);
throw new RuntimeException(ne);
When I run the application and try to invoke the lookup method my application gets the following exception:
SEVERE: exception caught
javax.naming.NameNotFoundException: No object bound to name java:comp/env/ejb/Se

Please... can someone help me?

The portable way to acquire the dependency is through java:comp/env or @EJB. Accessing the
global namespace directly is not recommended. If you use an ejb-ref, you need to define it
in the component environment within which you'll be looking up the dependency. So if you're
looking it up from an Application Client, you'll need to define the ejb-ref in application-client.xml.
Also, the ejb-ref-name is the portion of the string after java:comp/env. There is no automatic
"ejb" appended to it. If you do ic.lookup("java:comp/env/foo"), your ejb-ref-name would be "foo".
You can use @EJB but it can only be defined in certain managed classes such as the
Application Client main class.
You can find additional info in our EJB FAQ :
https://glassfish.dev.java.net/javaee5/ejb/EJB_FAQ.html

Setting a deployment context when using the embedded OC4J

I'm trying to debug a servlet using the embedded OC4J server. I have a simple project that includes a servlet source file and and a web.xml file. The web.xml file defines context
parameters that I want the servlet to read and use when it is deployed. However I don't know
how to get JDeveloper to set up the servlet context on the debugging environment to use the
contents of the web.xml file. Could anyone tell me how to do this? I cannot see how to
do this from the help files.
Many thanks in advance

The trick is to ensure that you use a 'Project with Web Module' rather than
'Empty Project' and then add a new 'HTTP Servlet'. When you do this
JDeveloper automatically creates a web.xml file. You can add context
parameters, or practically any other configuration items by right clicking
on the web.xml tree node inthe system navigator and selecting settings.
The web.xml file is saved into the directory specified by the 'HTML Root Directory' on the 'Input Paths' panel in the project settings dialog.

Deploying Stateful Session Bean

hi!
I've got a problem when deploying a Stateful SessionBean. It worked well for about 1 week. I changed a little thing in the BeanClass, and afterwards only got deployment errors. taking back the changes had no effect.
Furthermor the Error seems to be nonsens, because I deploy from a EAR, and this ear contains all Files of the Stateful SessionBean. The container seems to have problems to read the jar file within the ear file ...???

hi Jeff!
I tried some different tasks.
1.) removing all deployments (incl. app in server.xml) -> still error
2.) manually deploying to a "virgin" container -> still error
3.) manually deploying an old and stable version (runs on a colleages oc4j instance) -> still error
4.) copying app-dirs + config-dir from a colleage (its his running instance) -> STILL ERROR!!
5.) copying his whole J2EE-dir -> deployment works!
It looks like, that one of my deployments (out of Jdeveloper with admin.jar) has kicked my container and the container kept in tilt mode (to use a little flippermachine slang ;o)
Besides from joking, I still think it's a serious thing. I'm now going to install a whole fresh instance of Jdeveloper and OC4J. Hopefully afterwards I won't have these probs again.
If someone @ Oracle wants to take a look at these instance (like bugsearching) dont hesitate to contact me (I'll keep both version of the OC4J, running and tilt one).

Problem accessing a session bean running on a different port

Hi,
I am using weblogic7.0 as the application server. I craeted two EJB's and
deployed them in two ports, port 7001 and 7378. I can access the beans when I
deploy them in the same port. But, I am having problem when EJB1 'server1' accesses
EJB2 'server2' deployed in port 7378. Below is the code I am using to lookup the
bean.
Properties prop = new Properties();
prop.put(Context.INITIAL_CONTEXT_FACTORY,
"weblogic.jndi.WLInitialContextFactory");
prop.put(Context.PROVIDER_URL, "t3://localhost:7378");
Context ctx = new InitialContext(prop);
Object objref = ctx.lookup("java:comp/env/server2");
System.out.println("Inside the Object method "+objref);
iHome = (server2.InsertHome) objref;
System.out.println("Inside the iHome method "+iHome);
mInsert=iHome.create();
I am getting the following exception when I run the client. Can any one plaes
help me with the problem I am facing.
Thanks,
Ramya.

So it looks like mInsert is null causing the NPE. I think you'll have
to debug this one.

} finally {

Line 133 (mInsert.cleanup(con, ps);) is the call to close up the SQL connection
that is from EJB2. mInsert is the member variable of the Remote class from EJB2.
Thanks,
