Problem running RMI/IIOP sample (stateless bean)
Hi.
I am unable to run the RMI/IIOP stateless bean sample (Weblogic 6.1 on
Windows 2000). I have deployed the sample (iiop_ejb_stateless) and the
server is running. I checked in the admin console and the module is
deployed OK.
However, the client is unable to get the initial context and throws a
""We were unable to get a connection to the WebLogic server at
iiop://localhost:
Please make sure that the server is running."
error message on the command prompt. What could be wrong? Is there a
flag I need to throw on to get the server to enable IIOP based
connections?
Thanks in advance,

(although all the examples work on all releases). Also try substituting
localhost for your machine name, W2K does some fun tricks with DNS.

Problem running the OdpNetWs sample
Hi,
I have the following error when starting the OdpNetWebService sample (I must say that I work with Oracle8i DataBase instead of 9i, in case this would be the trouble...)

Transactions Sample RMI-IIOP Code
Hi,
Looking to the link below it appears that we can have RMI-IIOP applications
and clients that use JTA.
http://e-docs.bea.com/wls/docs61/jta/gstrx.html#1067532
Does anyone know of a RMI-IIOP sample that illustrates how transactions are
propagated from RMI-IIOP clients to RMI-IIOP applications?
Regards,
Dan Cimpoesu
But if you look to the diagram:
http://e-docs.bea.com/wls/docs61/jta/gstrx.html#1040200
it suggests that transactional context is passed from clients to RMI-IIOP
servers.
Am I wrong?

Hi,
Based on the links below:
http://e-docs.bea.com/wls/docs61/jta/trxrmi.html#1018506
http://e-docs.bea.com/wls/docs61/jta/gstrx.html#1067532
It appears that is possible to have distributed transactions across
RMI-IIOP
clients and RMI-IIOP applications (servers).
I followed up the "Transactions Sample RMI Code" section but it appearsthat
the transaction context is not propagated from client to server. I amalso
surprised by the note:
Note: These code fragments do not derive from any of the sampleapplications
that ship with WebLogic Server. They merely illustrate the use of the
UserTransaction object within an RMI application.
The above note suggests that there is no sample code available.
Is there anyone who successfully had RMI-IIOP applications (servers)
participating in distributed transactions?
Is there any sample code that illustrates RMI-IIOP applications(servers)
participating in distributed transactions?
If anyone thinks that this should work I will post my code that does not
work.

Dear Eduardo,
this bug doesn't seem to be fixed yet, neither

Even worse, with service pack 4 Weblogic

The property "enable-call-by-reference" has already

J2EE Server can handle this, is WebLogic using
a different IIOP than SUN ?
There are no problem with WebLogic, when
changing the business method from
"public Address retrieveAddress(String primaryKey)"
to
"public AddressValue retrieveAddress(String primaryKey)"
, but that's not object-oriented !
many thanks,
Reinhold BiedermannWe (actually, just me, I guess) have our wires crossed...
You are correct in that you have every reason to expect a signature that returns an interface to support marshaling of any concrete manifestation of that interface.
The bug fix was re-scheduled from SP3 to 4 and then into the (them imminent) 5.1.1 release... I will investigate what release vehicle it is languishing in and report back to this list.
The shame of it is that I found and fixed that bug quite a while ago...

I saw this topic in an old thread but couldn't find the answer. My
problem was the same, the client app was stuck at the line
obj = nc.resolve(path);
Could you post your solution if you know the answer to this problem.
Thanks a lot.Yes, you are right. I'm currently using jdk1.3. Is there a fix or do I
have to go back to jdk1.2? Thanks a lot.

As I said, apparently, you are trying to compile the IDL
client in java using the RMI client classes. THere are two
problems with this:
1-- you must compile the rmi class definitions into a
directory that can be easily excluded from the class path at
the time you compile the idl definitions.
2-- the idl definitions and the resulting classes are useless
wrt the rmi definitions and wls, so the resulting classes must
be compiled into directories other than those used by wls and
the rmi clients.
Another way to look at this is as follows:
To compile the rmi definitions, you do:
set ORIGINALCLASSPATH=CLASSPATH
set CLASSPATH=../fooclasses;$CLASSPATH
javac -d ../fooclasses rmi/FooImpl.java
Then,
-- you compile the jrmp classes as:
rmic -d ../jrmpclasses rmi.FooImpl
-- you compile the weblogic classes as:
java weblogic.rmic -d ../wlsclasses rmi.FooImpl
that is, you are allowed to compile from the same
implementation class so long as it is compliant
-- you compile the rmi-iiop classes as:
java weblogic.rmic -iiop -d ../rmiiiopclasses rmi.FooImpl
that is, as with jrmp and wls, the rmi-iiop classes share the
same base type definitions and implementation.
However, the idl classes are another matter. To compile the
idl classes, you must generate the idl, generate the java
files and generate the idl class files into another, separate
directory, one which does not include any of ../fooclasses,
../jrmpclasses, ../wlsclasses or ../rmiiiopclasses
directories.
That is,
java weblogic.rmic -idlDirtecory ../idl ...
set CLASSPATH=ORIGINALCLASSPATH
set CLASSPATH=../idlclasses;CLASSPATH
cd ../idl
idl2java rmi/Foo.idl
javac -d ../idl rmi/*.java
Hope this helps...

Exception while getting the server instance. Stateless bean problem
Hi,
New to OC4J, I'm moving an ear that was running ok under jboss.
1- The wep app deploys. This is a piece of code inside the init() method of a struts plugin:
System.out.println("0");
AddressFacadeHome addressFacadeHome = HomeFactory.getAddressFacadeHome();
System.out.println("1.0");
AddressFacade addressFacade = addressFacadeHome.create();
System.out.println("1.5");
2- The code is run when the web app is initialized. This is the error message I get. system.out show that the error occurs on addressFacadeHome.create().
AddressFacade is a remote/local stateless bean. HomeFactory returns the jndi lookup/narrow of the remote object.

My guess is that it's a jaas issue (because i see security and getCurrentUser), but at init time, no user is authenticated.
Any clue would be very much appreciated. Let me know if I can provide anything else, such as deployment descriptors.
Thanks,
Christophe.After spending some time on this, I looked at the source code for com.evermind.server.ThreadState
This is the code that throws the exception:
if(applicationThread != null && applicationThread.httpHandler != null && applicationThread.servletInfo != null)
try
server = applicationThread.httpHandler.request.getApplication().getApplication().getServer();
catch(Throwable t)
System.out.println("caught exception while getting the server instance " + t.getMessage());
t.printStackTrace(System.out);
It looks like this method expects a httpRequest, and would find null because I'm in the servlet.init()
(at least, that's my interpretation)
I tested my code (the remoteFacade.create()) inside of a jsp, and it worked...
So, the next logical question is:
Can I make EJB calls from within the init method of a servlet? (or more specifically from a struts plugin, which I believe should be more or less the same thing)
If so, do I need to take extra steps?
Again, any experience/help on this will be much appreciated.
Thanks,
Christophe. -
Is there any sample RMI-IIOP application using distributed transactions
Hi,
Based on the links below:
http://e-docs.bea.com/wls/docs61/jta/trxrmi.html#1018506
http://e-docs.bea.com/wls/docs61/jta/gstrx.html#1067532
It appears that is possible to have distributed transactions across RMI-IIOP
clients and RMI-IIOP applications (servers).
I am surprised by the note:
Note: These code fragments do not derive from any of the sample applications
that ship with WebLogic Server. They merely illustrate the use of the
UserTransaction object within an RMI application.
The above note suggests that there is no sample code available.
Is there any sample code that illustrates RMI-IIOP applications (servers)
participating in distributed transactions?
Regards,
Dan CimpoesuTransaction examples for IIOP are in the works for the next release.

Hi there,
I have had alot of problems running a small RMI program.
It has now boiled down to a java.lang.NoClassDefFoundError
when i try to use my policy file.
The program complies, when i run javac *.java
It also creates the stub, when i run rmic.
I have trawled alot of forums and the closest answer i got was "add your classpath".
As im a student of java, this does not really tell me much.
The class/java files are in
C:\Documents and Settings\MONDARIZ\workspace\RmiHello\server
The policy file is also in the folder.
I must add, that the program is from an example, so i would not think there is any coding errors.
Also when i run it en eclipse, i get "Hello server failed: java.security.AccessControlException: access denied (java.net.SocketPermission 127.0.0.1:1099 connect,resolve)"
So it seems something is running.The answer you found is correct. Java needs to know where to find the class files for execution.
For starters, use the environment variable CLASSPATH. Set the value to:
C:\Documents and Settings\MONDARIZ\workspace\RmiHello\server
This way whatever you run (RMI Registry, Server, Client) has the proper class path. When you get everything running ok, then you can look into other methods of specifying where the class files are found.
Eclipse, as well as command line Java starts, need to find the policy file. Set up this:
-Djava.security.policy=C:\Documents and Settings\MONDARIZ\workspace\RmiHello\server\your_policy_file.xxx -
Problem of running rmi applet and client for Javacard 3.0.2 Connected
Need help for running rmi application for Java Card 3.0.2 connected version. I am trying to move a working rmi applet & client from 3.0.2 Classic version to Connected version. Then I found that they are so different and I have no idea how to run my application :(
Here are what I have done:
- I have modified the Classic HelloWorld applet to an rmi applet. It is OK when I build and run the application in netbeans. The Applet can be selected successfully.
My problems are:
- How to connect a rmi client to the rmi applet? Here are what I have done:
+ Run rmi applet in netbeans
+ Run 'rmic' command to generate stub
+ Run rmiregistry outside of netbeans
+ Build and run rmi client application outside of netbeans by typing "ant all"
However, the rmi client was not able to connect to the applet:
[java] java.net.ConnectException: Connection refused: connect
Would this be a problem of netbeans? Could someone tell me how to run rmi applet/client within or outside netbeans. Thanks a lot!Well finally I figured out that CREF-emulators (from JCDK 2.2.1, 2.2.2, 3.0.1 classic) do not support cryptographic extensions at all.
BUT JCWDE(from JCDK 2.2.1, 2.2.2) - support, but this kind of simulator quite hard to use, because it does not have state between launches.
About CJCRE(from JCDK 3.0.1 connected) - still don't know, seems not support cryptographic extensions. -

Problem running Java client of EJB deployed on WebSphere
Hi,
I am using websphere studio 5.1.2 with fix pack 3. I have a sample Stateless Session Bean (EJB) deployed and running on websphere.
I wrote a small Java client program as below.
import java.util.Hashtable;
import HelloJavaHome;
import HelloJava;
import javax.naming.InitialContext;
import javax.naming.Context;
import javax.ejb.EJBHome;
import javax.ejb.EJBObject;
public class RemoteConn {
public static void main(String[] ar) throws Exception{
String greeting = "";
try{
Hashtable env = new Hashtable();
//env.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.websphere.naming.WsnInitialContextFactory");
//env.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.ejs.ns.jndi.CNInitialContextFactory");
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.ws.naming.util.WsnInitCtxFactory");
//env.put(Context.PROVIDER_URL, "corbaloc:iiop:myhost.mycompany.com:2809/NameServiceCellPersistentRoot");
env.put(Context.PROVIDER_URL, "iiop://localhost:2809");
System.out.println("Before creating context ");
InitialContext initContext = new InitialContext(env);
System.out.println("Before looking up HelloJavaHome.");
//Object obj = initContext.lookup("java:comp/env/ejb/HelloJavaHome");
Object obj = initContext.lookup("ejb/HelloJavaHome");
System.out.println("After lookup javahome.");

HelloJava remote = home.create();
greeting = remote.getGreeting("John");
catch(Exception e){
e.printStackTrace();
System.out.println("Greeting::"+ greeting);
I did not have any problem if I write and run this client from Websphere studio environment..
However its giving lot of compilation and runtime errors when I tried to run from command line.
I could eliminated compilation errors by setting the below jar files in the classpath.

How write rmi-iiop over ssl with weblogic server 6.1?
Hello,
I have written an appication like this:
- An EJB server running on Weblogic server 6.1
(named: BankServerHome)
-A java client calling the BankServer.
Platform: windows 2000 - jdk1.4
Now I want to secure the communication with SSL protocol.
I have done this:
-generate a key peer with weblogic service named certificate.
-send the CSR to a CA and place the answer into the weblogic
server certificate directory.
-update path for ServerCertificateChainFileName,
ServerCertificateFileName, ServerKeyFileName into config.xml.
-launch weblogicServer
-> server certificate is recognized
-> listening port 7001 and 7002.
(-stop weblogicServer!)
At now, all is all right, errors come hereafter:
Then I follow the guideline "Programming weblogic Security" (version of 30/07/2001).
"To use RMI over IIOP over SSL with a Java client, do the following:
2. Extend the java.rmi.server.RMISocketFactory class to handle SSL socket

3. Run the ejbc compiler with the -d option.
4. Add your extension of the java.rmi.server.RMISocketFactory class to the
CLASSPATH of the Java client.
5. Use the following command options when starting the Java client:

-Dorg.omg.CORBA.ORBSocketFactoryClass=implementation of java.rmi.server.RMISocketFactory
-Dssl.certs=directory location of digital certificate for Java client
-Dssl.key=directory location of private key for Java client"
At step 3. I found into documentation that -d is linked to a directory name.
When I run ejbc with this option -d I have the message:
"ERROR: You must specify an output directory or jar with the -d option to weblogic.ejbc."
% So what option can I use to run ejbc for secure usage?
At step 5. Whatever I write for -Dorg.omg.CORBA.ORBSocketFactoryClass,

Then I can not create a socket with my client.
The folowing exception is raised:
javax.naming.CommunicationException [Root exception is java.net.ConnectException:
No server found at T3S://localhost:7002]
So, my questions are:
% Why -Dorg.omg.CORBA.ORBSocketFactoryClass must be known by the client and not
the server?
My java client part, managing connection is:

First off 1.4 isn't supported as yet. That is probably part of the problem.
You also must use a corba URL from the client in order for this to work for instance:
If you are using WLInitialContextFactory:
corbaloc:iiop:localhost:7001/NameService
If you are using CNCtxFactory:
iiop://localhost:7001
Using rmi: is the wrong thing to do - that will use jrmp or t3.
However, I suggest that you raise a call with support since there is
some other trickiness with getting SSL working. We hope to have this
much improved in SP2.

Noob Question: Problem with Persistence in First Entity Bean
Hey folks,
I have started with EJB3 just recently. After reading several books on the topic I finally started programming myself. I wanted to develop a little application for getting a feeling of the technology. So what I did is to create a AppClient, which calls a Stateless Session Bean. This Stateless Bean then adds an Entity to the Database. For doing this I use Netbeans 6.5 and the integrated glassfish. The problem I am facing is, that the mapping somehow doesnt work, but I have no clue why it doesn't work. I just get an EJBException.
I would be very thankfull if you guys could help me out of this. And don't forget this is my first ejb project - i might need a very detailed answer ... I know - noobs can be a real ....
So here is the code of the application. I have a few methods to do some extra work there, you can ignore them, there are of no use at the moment. All that is really implemented is testConnection() and testAddCompany(). The testconnection() Methode works pretty fine, but when it comes to the testAddCompany I get into problems.
Edit:As I found out just now, there is the possibility of Netbeans to add a Facade pattern to an Entity bean. If I use this, everythings fine and it works out to be perfect, however I am still curious, why the approach without the given classes by netbeans it doesn't work.
public class Main {
private EntryRemote entryPoint = null;
public static void main(String[] args) throws NamingException {
Main main = new Main();
main.runApplication();
private void runApplication()throws NamingException{
this.getContext();
this.testConnection();
this.testAddCompany();
this.testAddShipmentAddress(1);
this.testAddBillingAddress(1);
this.testAddEmployee(1);
this.addBankAccount(1);
private void getContext() throws NamingException{
InitialContext ctx = new InitialContext();
this.entryPoint = (EntryRemote) ctx.lookup("Entry#ejb.EntryRemote");
private void testConnection()
System.err.println("Can Bean Entry be reached: " + entryPoint.isAlive());
private void testAddCompany(){
Company company = new Company();
company.setName("JavaFreaks");
entryPoint.addCompany(company);
System.err.println("JavaFreaks has been placed in the db");
}Here is the Stateless Session Bean. I added the PersistenceContext, and its also mapped in the persistence.xml file, however here the trouble starts.
import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
@Stateless(mappedName="Entry")
public class EntryBean implements EntryRemote {
@PersistenceContext(unitName="PersistenceUnit") private EntityManager manager;
public boolean isAlive() {
return true;
public boolean addCompany(Company company) {
manager.persist(company);
return true;

return false;
public boolean addBillingAddress(long companyId) {
return false;
public boolean addEmployee(long companyId) {
return false;

return false;

Best regards and happy coding
Taggert
Edited by: Taggert_77 on Jun 8, 2009 2:27 PMWell I don't understand this. If Netbeans created a Stateless Session Bean as a facade then it works -and it is implemented as a CMP, not as a BMP as you suggested.
I defenitely will try you suggestion, just for curiosity and to learn the technology, however I dont have see why BMP will work and CMP won't.
I also don't see why a stateless bean can not be a CMP. As far as I read it should not matter. Also on the link you sent me, I can't see anything related to that.
Maybe you can help me answering these questions.
I hope the above lines don't sound harsh. I really appreciate your input.
Best regards

Stateless bean giving error when deployed through j2ee 1.3RI
I have written a simple stateless bean and deployed through j2ee 1.3 RI
Context initial = new InitialContext(h);
Object obj = initial.lookup("SampleObject"); // SampleObject -jndi name
SampleHome home = (SampleHome)PortableRemoteObject.narrow(obj, SampleHome.class);
But when running the Client , getting the error
java.lang.ClassCastException
at com.sun.corba.se.internal.javax.rmi.PoartableRemoteObject.narrow(Unknown Source)
at javax.rmi.PortableRemoteObject.narrow(Unknown Source) at SampleClient.main(SampleClient.java:27)
Is it a system error or whatHi sessionbean,
The most common cause of this exception is when the RMI-IIOP stubs are not found within the client's classpath. The client stubs are returned from the deployment step.
Also, it's better to use the no-arg initial context constructor "new InitialContext()" and let the J2EE 1.3 RI code bootstrap the correct naming service.

4. Add your extension of the java.rmi.server.RMISocketFactory class to the
CLASSPATH of the Java client.
5. Use the following command options when starting the Java client:
-xbootclasspath/a:%CLASSPATH%
-Dorg.omg.CORBA.ORBSocketFactoryClass=implementation of java.rmi.server.RMISocketFactory
-Dssl.certs=directory location of digital certificate for Java client
-Dssl.key=directory location of private key for Java client"
At step 3. I found into documentation that -d is linked to a directory name.
When I run ejbc with this option -d I have the message:
"ERROR: You must specify an output directory or jar with the -d option to weblogic.ejbc."
% So what option can I use to run ejbc for secure usage?
At step 5. Whatever I write for -Dorg.omg.CORBA.ORBSocketFactoryClass,
this pointed class is not instanciated.
Then I can not create a socket with my client.
The folowing exception is raised:
javax.naming.CommunicationException [Root exception is java.net.ConnectException:
No server found at T3S://localhost:7002]
So, my questions are:
% Why -Dorg.omg.CORBA.ORBSocketFactoryClass must be known by the client and not
the server?
My java client part, managing connection is:
-------------------BEGIN OF CONNECTION MANAGER-------------------
Properties env = new Properties ();
// Shouldn't have to do this, but for now you must
if ( factory.equals ("weblogic.jndi.WLInitialContextFactory") ) {
env.put ("java.naming.provider.url", "t3s://localhost:7002");
InitialContext context = new InitialContext (env);
BankSessionServerHome bssh = (BankServerHome) context.lookup("BankServerHome");
BankServer = bssh.create();
-------------------END OF CONNECTION MANAGER-------------------
I have also try
env.put ("java.naming.provider.url", "corbaloc:iiop://localhost:7002");
but it throws the following error
javax.naming.InvalidNameException: url does not conatin !!!
% What is the code for the java client allowing connection with the ejb?
% And better, can I have a sample example for rmi-iiop over ssl?
(...wlserver6.1\samples\examples\iiop\ejb\stateless\rmiclient\client.java do not
speak ssl!)
Any help will be appreciate from you...
Best Regards.

I have written an appication like this:
- An EJB server running on Weblogic server 6.1
(named: BankServerHome)
-A java client calling the BankServer.
Platform: windows 2000 - jdk1.3
Now I want to secure the communication with SSL protocol.
I have done this:
-generate a key peer with weblogic service named certificate.
-send the CSR to a CA and place the answer into the weblogic
server certificate directory.
-update path for ServerCertificateChainFileName,
ServerCertificateFileName, ServerKeyFileName into config.xml.
-launch weblogicServer
-> server certificate is recognized
-> listening port 7001 and 7002.
(-stop weblogicServer!)
At now, all is all right, errors come hereafter:
Then I follow the guideline "Programming weblogic Security" (version of 30/07/2001).
"To use RMI over IIOP over SSL with a Java client, do the following:
2. Extend the java.rmi.server.RMISocketFactory class to handle SSL socket
connections. Be sure to specify the port on which WebLogic Server listens for
SSL connections. For an example of a class that extends the
java.rmi.server.RMISocketFactory class, see Listing 4-22.
3. Run the ejbc compiler with the -d option.
4. Add your extension of the java.rmi.server.RMISocketFactory class to the
CLASSPATH of the Java client.
5. Use the following command options when starting the Java client:
-xbootclasspath/a:%CLASSPATH%
-Dorg.omg.CORBA.ORBSocketFactoryClass=implementation of java.rmi.server.RMISocketFactory

-Dssl.key=directory location of private key for Java client"
