Intercept J2EE Client EJB2.x Invocations

Hi all,
I want to intercept EJB2.x invocations (*all requests and responses*) *only from
J2EE Client application side*(from WebSphere, Weblogic
vendors)
not from server side. My target is to record/save these invocations in XML.
Also i don't have any access to the source code of this existing J2EE Client application(have only binary distribution) so i cannot modify
anything in client application code.
I found this article with various possiblities
[http://www.elca.ch/site_repository/resources/InvokersNeedToBeAddedToJ2EE5_2.pdf]
1. CORBA PortableInterceptors but Weblogic has no support for PortableInterceptors.
2. Java's Dynamic Proxy Classes - maybe someone can elaborate it
3. AOP - which framework allows me to intercept ejb invocations only from client side without knowing the client internals
If anybody who has idea to solve this problem please help me.

No response. Very strange!

Running a J2EE client on a Remote machine

How do you run a J2EE client application on a remote machine?

and what about running on remote client .
the things i know is , ok leave i am pasting a client which is on different machine (i.e not on the machine on which the server is ) copy
1. the client jar file which is return when u deploy the beans .
* Remember to add jar path in the class path
2. client class / java file on the remote client
and then run the client
for eg . client code
change Properties 's prop accoding to u
import javax.ejb.*;
import javax.naming.*;
import java.rmi.*;
import javax.rmi.PortableRemoteObject;
import java.util.*;
public class TestClient {
public static void main(String[] args) {
try {
     System.out.println("IDFactory");
     Properties prop = new Properties();
     /* prop.put("org.omg.CORBA.ORBInitialHost","192.168.10.5");
     prop.put("org.omg.CORBA.ORBInitialPort","1050");
     prop.put(Context.PROVIDER_URL, "iiop://192.168.10.5:1050");
     prop.put(javax.naming.Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.cosnaming.CNCtxFactory");
     InitialContext initial = new InitialContext(prop);
     Object objref = initial.lookup("TimeReport/Data/TestHome");
     TestHome home = (TestHome)PortableRemoteObject.narrow(objref,TestHome.class);
     System.out.println("looking up IDFactory Session Bean");
     Test TestRemote = home.create();
     System.out.println("IDFactory Created ");
     long roleID = TestRemote.getID("TR_ROLE","Role_ID");
     System.out.println("RoleID is " + roleID);
     TestRemote.remove();
     } catch (Exception ex)
     System.err.println("Caught an unexpected exception!" + ex.getMessage());
     ex.printStackTrace();
if it works then let know on [email protected]

Help:How can I run the J2EE Client Application? Thanks

Help:How can I run the J2EE Client Application that will access the remote J2EE1.4 application server which runs on another host computer?
I have developped a stateles senterprise java bean name converter and deloyed it in the j2ee1.4 application server on the host machine A. The converterbean provides the remote home interface and remote interface. At the same time I have developped the j2ee application client named convertappclient. When I access the conveter bean at host computer A through the script 'appclient.bat' as 'appclient -client convertappclient.jar', the client can access the bean sucessfully. Now I want to access the bean through the script 'appclient.bat' at host computer B,what files should I copy from host computer A to host computer B;and what the command line should be like? Thanks!
The following are the code of the enterprise java bean and it's home interface .
The client code is also provided.
The enterprise java bean:
package converter;
import java.rmi.RemoteException;
import javax.ejb.SessionBean;
import javax.ejb.SessionContext;
import java.math.*;
public class ConverterBean implements SessionBean {
BigDecimal yenRate = new BigDecimal("121.6000");
BigDecimal euroRate = new BigDecimal("0.0077");
public ConverterBean() {
public BigDecimal dollarToYen(BigDecimal dollars) {
BigDecimal result = dollars.multiply(yenRate);
return result.setScale(2, BigDecimal.ROUND_UP);
public BigDecimal yenToEuro(BigDecimal yen) {
BigDecimal result = yen.multiply(euroRate);
return result.setScale(2, BigDecimal.ROUND_UP);
public void ejbCreate() {
public void ejbRemove() {
public void ejbActivate() {
public void ejbPassivate() {
public void setSessionContext(SessionContext sc) {
The bean's remote home interface :
package converter;
import java.rmi.RemoteException;
import javax.ejb.CreateException;
import javax.ejb.EJBHome;
public interface ConverterHome extends EJBHome {
Converter create() throws RemoteException, CreateException;
The bean's remote interface:
package converter;
import javax.ejb.EJBObject;
import java.rmi.RemoteException;
import java.math.*;
public interface Converter extends EJBObject {
public BigDecimal dollarToYen(BigDecimal dollars) throws RemoteException;
public BigDecimal yenToEuro(BigDecimal yen) throws RemoteException;
The j2ee application client:
import converter.Converter;
import converter.ConverterHome;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.rmi.PortableRemoteObject;
import java.math.BigDecimal;
public class ConverterClient {

Context myEnv = (Context) initial.lookup("java:comp/env");
Object objref = myEnv.lookup("ejb/SimpleConverter");
ConverterHome home =
(ConverterHome) PortableRemoteObject.narrow(objref,
ConverterHome.class);
Converter currencyConverter = home.create();
BigDecimal param = new BigDecimal("100.00");
BigDecimal amount = currencyConverter.dollarToYen(param);
System.out.println(amount);
amount = currencyConverter.yenToEuro(param);
System.out.println(amount);
System.exit(0);
} catch (Exception ex) {
System.err.println("Caught an unexpected exception!");
ex.printStackTrace();

NameNotFoundException - ${j2ee.client} not bound

Good day, all. I'm new to J2EE, so apologies up front if this is a brain-dead
question. I have done some searching around on the site, and have found similar
issues, but none which contain a working solution for me, as far as I can tell.
I'm attempting to write a J2EE client application using JBoss. I have a main function
which is attempting to look up entries from the server's Global JNDI context, and isn't
finding them.
My main():

               // v--- Explosion occurs below: ---v
               String lookupName = (String)ctx.lookup("java:comp/env/name_space_root");
               Context globalCtx = (Context)ctx.lookup(lookupName); // I don't ever get here.
               if (log.isInfoEnabled())
                    log.info(null,"Loaded Global Context");
               System.out.println("Yay");
               System.out.println(globalCtx);
          catch (NamingException e2)
               log.warn("There was an error looking up the name_space_root: " + e2);

kevjava [added application-client.xml]

I'm not familiar with the specifics of how the JBoss implementation requires that Application Client
components be executed so I'd recommend checking their documentation. There is often a
special command needed to run an Application Client within an Application Client container. It's
typically more than just configuring the client to bootstrap a particular naming provider.
For example, in the Java EE SDK, we have a special command called "appclient" that is used to
start an Applicaiton Client component. The Application Client container bootstraps the
correct naming provider, sets up the private component naming environment (java:comp/env),
handles any authentication, etc. You can find more information on the difference between
an Application Client and a "stand-alone java client" in our EJB FAQ :

J2EE client mapping in WL6

I've read the not-so-good dox about running a J2EE client in WL6:
- make a jar packaged with the standard META-INF/application-client.xml
- put an xml called <jarname>.runtime.xml in the dir with the client jar
(for WL6 specific jndi mappings)
- run the jar with weblogic.j2eeclient.Main [jar] urlthis is cumbersome in development. my J2EE client is mostly made of junit
testcases that call entities and session beans. There are dozens of "Main"
classes in the jar, that I might want to run individually!
I would like to run the testcases directly using the compiled classes
directory - but then the jndi mappings between the standard, logical names
like "java:comp/env/ejb/mySessionHome" and the WL-specific names like
"ejb.myapp.mySessionHome" fail.
actually, if I run the client using in code the actual WL6 jndi names, no
deployment info is necessary, but I want to use in code only the logical
names.
so, my question is : how do I run an unpackaged client that picks up the
jndi mappings specified in the .runtime.xml ??
Edo
PS - I basically want to replicate on the client-side the way I work on the
server-side : I use WL6 dynamic deployment of an unpackaged ear : no
explicit calls to jar and ejbc - which helps my code-complie-test cycle a
lot !

Hi Sandy,
If I understand you correctly, then you are asking how to make
a stand-alone java client, right? According to the J2EE spec, a
stand-alone java client also needs to be deployed to a container.
A long time ago (before OC4J, when there was only OrionServer)
I struggled for about a week before finally figuring out how to
do this.
However, I then discovered that, with OrionServer (and therefore
also with OC4J), your stand-alone java client does not have
to be deployed to a container and can be launched from the command
line with the "java" command.
If you do want to deploy your java client, then the only way
I know to launch it is by using the "applicationlauncher.jar"
file. This file was part of the first OC4J (version 1.0.2.2).
It disappeared in the next version (9.0.2) and now has reappeared
in the latest version (9.0.3) -- go figure! Like I said, by the
time I started using OC4J, I was only using non-deployed clients,
so I had no need for "applicationlauncher.jar", so the fact it
was missing from version 9.0.2 didn't affect me.
In any case, I recall information on how to use the "applicationlauncher.jar"
file on the following web sites:
http://www.orionserver.com
http://www.orionsupport.com
http://www.atlassian.com
http://www.elephantwalker.com
I also recall answering similar questions several times previously
on this forum, so a search of the forum archives may also help.
I hope I have correctly interpreted your question and given you
a helpful answer.
Good Luck,
Avi.

ABAP Client and J2EE client mismatch

Hello,
we detected mismatch between default ABAP login client and J2EE client.
Now we need to change J2EE client to default ABAP client.
Its ABAP + JAVA installation and diff. occured after client copy.
Can you please let us know where we need to change all setting for j2ee engine like default client for UME, sld etc.
Best Regards,
Tushar

Hello. By default JAVA used the 001 client in ABAP+JAVA installation, be cautious with change it.
you can chage it through Config tool :
http://help.sap.com/saphelp_nw70/helpdata/EN/0b/50ad3e1d1edc61e10000000a114084/frameset.htm
or from UME --> configuration --> ABAP system. You need to read about change datasources :
http://help.sap.com/saphelp_nw70/helpdata/EN/7e/a2d475e5384335a2b1b2d80e1a3a20/frameset.htm

J2EE Client Application (weblogic.ClientDeployer)

Hello,
I'm experimenting with the ClientDeployer utility as described in the 6.1
documentation, and I face some odd behavior.
I created a jar file (cli.jar) containing the class files of my client application,
and a META-INF/application-client.xml file.
This jar file then gets stored in an ear file, together with a cli.runtime.xml
file
and a META-INF/application.xml file.
Afterwards, I tried running this client application by using
java weblogic.ClientDeployer clients.ear cli
Now, all of this works, as long as I leave the cli.runtime.xml file in the
current directory. But as soon as I remove this file from the current
directory, it stops working. This means that ClientDeployer doesn't read
the cli.runtime.xml file from the ear file, but only from the current directory.
Is that the way it is supposed to work ? I would expect it to read the
runtime file form the ear file ?
Thanks,
Francois Staes.

Get URL for J2EE client application

Please forgive me if this question has an obvious answer, but I can't see it.
Once Web Start has downloaded and started my J2EE Swing application client, how can my client get the name of the host (or entire URL) from which the client was downloaded?
I would rather not have to hard code this into my client, so that the WAR file I deploy to the server is platform independent.
bobj5000

Use the JNLP BasicSevice API getCodeBase() to get the URL of the server.
BasicService bs = (BasicService)ServiceManager.lookup("javax.jnlp.BasicService");
URL url = bs.getCodeBase();
Hope this helps

I have the same problem with the default ports.
Did you find a solution?
What's your JNDI factory, what's your provider url?
Which version of the oracle application server are you using?

Small weblogic.jar for jms/j2ee clients of weblogic

          We are trying to create a smaller footprint for the ~38M weblogic.jar for distribution
          to our client applications to use the JMS and J2EE features of Weblogic 7.0sp2.
          I attempted to use the whitepaper document distributed by BEA for creating a smaller
          jar file, but it did not work. Has anyone else in the user community successfully
          created the jar file and if so could they give me some insight on how they did
          it.
          Thanks,
          Ashish


Hi Ashish,
          I've personally used the "URL" class loader option with success,
          and I know that several customers have also used this option, as
          well as the other options for years. Feel free to
          post more detail than "it did not work", and I may be able
          to help you out.
          Tom, BEA
          P.S. If 8.1 is an option, you may with to consider using the
          thin client jars it supplies.

I have such a problem with Bea weblogic 6.1 EJB Server, trying to connected it from Tomcat (don't know, if it would work anyway):
If I try to lookup with standard "java:comp/env/ejb/ObjRemote", it tell's me there is no comp/env/ejb Object !
All examples/docu I read for this topic told me to call lookup("ObjRemote").
So look it up this way: simply with this name lookup("ObjRemote")...

Dubugging a j2ee client

I am using sun reference implementation for j2ee server and can easily run my client code with runclient bat file.
but how to I debug my client? Is it true that I can not run my client code as a standalone app?

Hi,
You can run u'r client as a standalone application, without the use of runclient. Just use the following code:
Context initial = new InitialContext();
Object objref = initial.lookup(args[0]);
FibHome home =
(FibHome)PortableRemoteObject.narrow(objref,
FibHome.class);
Do not use the other reference which is mentioned in the tutorial. Here FibHome is the home interface. I hope this solves u'r problem.

VC8 clients and native invocation API

Hi,
Could someone from Sun tell me whether JNI invocation API for the 1.5.0_07 Windows JVM supports .NET clients compiled with Visual C++ 8?
I have an ASP.NET application that calls into the JVM through the JNI invocation API. I know that there were problems with VC7 clients calling into the 1.3 and 1.4 JVM's (they only surfaced under high concurrency), but I was told that the 1.5 JVM would better support .NET clients.
Thanks...

J2EE clients over an intranet

Hi,
suppose i have swing clients in my j2ee app and i deploy all of them (clients, sessionbeans, entitybeans, daos, etc... ) on the server (the one that's hosting the app, of course).
I'm on an intranet and i want some of the remote computers (the ones inside intranet) to run their swing clients.
I don't know exactly what happens, as i'm a beginner!
The swing client is run from the remote pc right?
So, you gotta have the client app "installed" over there!
Then, what exactly is the necessity of having to deploy the clients with the j2ee applicatio???
Is it for the server to think something like "only client applications like the one deployed here can access the j2ee app" ???
So, does it mean that any client app the I want to run over the j2ee app need to be deployed???
thanks a lot,
ltcmelo

Not really!
My real questions are theese ones...
[from the first email]
Then, what exactly is the necessity of having to deploy the clients with the j2ee applicatio???
Is it for the server to think something like "only client applications like the one deployed here can >>access the j2ee app" ???
So, does it mean that any client app the I want to run over the j2ee app need to be deployed???If you still have some more answers...
thanks already,

Setting the -client option on invocation of Java via JavaApplicationStub

I'm in my info.plist. I've added VMOptions. I've tried
<key>Java</key>
<dict>
<key>VMOptions</key>
<array>
<string>-client</string>
</array>
</dict>
I've tried
<key>Java</key>
<dict>
<key>VMOptions</key>
<string>-Xclient</string>
</dict>
And yet when I run my app and look in System.getProperties() I see
java.vm.name=Java HotSpot(TM) 64-Bit Server VM
When what I wanna see is
java.vm.name=Java HotSpot(TM) Client VM
I do see that when I invoke Java from the command line.
I also have the 'open in 32-bit mode' checked. It doesn't seem to make a difference.
What am I doing wrong?

Yes, I have. I can't seem to get the JVM to take any VMOptions at all. I tried using the Jar Bundler too and got the same result. Here's my entire Info.plist... if there's anything obvious I'm missing, please let me know.
