Jdk 1.2 clients running ejb deployed on oracle 8.1.5

Oracle claims that it is possible to run jdk 1.2 clients with ejb on oracle 8.1.5 in the faq : http://technet.oracle.com/products/oracle8i/htdocs/jserver_faq/815faq0012.html
If you have JDK1.2 on the client side and:
8.1.5 clients connecting to an 8.1.5 server: This does not work, because of conflicts with the ORB supplied in JDK1.2.
8.1.5 clients connecting to an 8.1.6 server: This does not work, because of conflicts with the ORB supplied in JDK1.2.
8.1.6 clients connecting to an 8.1.5 server: This works provided the "server" portion of the application is developed/loaded using the client side tools and jars that are supplied with 8.1.5.
What do they meen with 8.1.6 clients? and how to make 8.1.6 clients?

Oracle 8.1.6's JVM uses JDK 1.2. Oracle's 8.1.6 JDBC drivers support JDBC2 and JDK2. The 8.1.6 drivers are available for download from OTN under the Technologies section.
If you develop a client (application, applet, servlet, JSP, etc.) using the Oracle 8.1.6 JDBC drivers, then this is considered an Oracle 8.1.6 client.

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.");
HelloJavaHome home = (HelloJavaHome) javax.rmi.PortableRemoteObject.narrow(obj, HelloJavaHome.class);
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.
testclient.jar; (client jar of my EJB)
j2ee.jar;
naming.jar;ras.jar;
wsexception.jar;
bootstrap.jar;
namingclient.jar;
websphere.jar;server.jar;
ejbcontainer.jar;
ecutils.jar;
Now it is throwing runtime error after the statement, "Before looking up HelloJavaHome.", has printed. Here is the stack trace of exception ..
Exception in thread "main" java.lang.NoClassDefFoundError: com.ibm.CORBA.iiop.GlobalORBFactory

Memory leak in a client using EJBs deployed in a Bea Weblogic 10.0.0 cluste

Hi all,
We are having a memory leak in a client using stateless EJBs deployed in cluster. The client is a Tomcat 6.0.18 with java 6 but it is reproduced using Tomcat 5 with java 5. The client is calling a Weblogic Server 10.0 making
calls to an EJB deployed in cluster that has two instances installed in two different machines.
The client works fine if we shutdown one of the server instances and so when the client is using only one instance.
Resuming the environment:
Client Side:
1 HP-Itanium machine with HP-UX.
1 Tomcat 6 with java 6 (reproduced with java 5)
Bea Weblogic client (wlclient.jar) for Weblogic 10.0.0
Server Side:
2 HP-Itanium machines with HP-UX
Bea Weblogic Server 10.0.0 installed in both machines
An unique domain
Two Bea instances (one per machines) associated to a Bea Cluster
EJBs deployed in both instances
We have monitored the memory consumed in Tomcat and we have noticed that the VM memory PS OLD GEN grows up permanently when we make tests having the two server side Bea Instances up. We have extended
the memory VM parameters in Tomcat client till 1G and it's only a way to delay the end: the free memory is empty, the GC is not able to free no more byte and the CPU is 100% consumed by the GC work. At the end Tomcat Client
doesn't accept more http petitions and must be restarted.
Besides, we have studied the VM memory in Tomcat using jmap and importing it using Eclipse Memory Analyzer. We have seen some strange memory blocks of several Mbytes that are always growing up and that are stored
under data structures in the package com.sun.corba:
com.sun.corba.se.impl.legacy.connection.SocketFactoryConnectionImpl (4.5Mb)
|
-> com.sun.corba.se.impl.transport.CorbaResponseWaitingRoomImpl
|
-> java.util.Hashtable
|
-> java.util.Hashtable$Entry
|
-> java.util.Hashtable$Entry
-> java.util.Hashtable$Entry
-> java.util.Hashtable$Entry
Has anybody any idea about this problem?
Thanks in advance.

Entity EJB deployment on Oracle through JDeveloper 3.2

I have a project which is using Oracle 9iAS as the for the web server. There were intial plans to use the 8i database within the 9iAS machine as the place where the EJBs would be stored. There was a comment from the Oracle support people that the EJBs would be better off stored on the backend. We are trying to do the same.
We have experienced mainly two problems
1) While trying to deploy the container managed beans through JDeveloper, just after creating the deployment profile, an error ORA - 00904 comes up. (no columns). Then there is a prompt to install BC4J. On doing that the error comes up again and while it goes further, it says 'Exhausted ResultSet'. But the BMP entity beans are working OK.
2) We had a bug report from the Oracle people on entity bean support through JDeveloper on non-NT machines. But we have been trying to deploy beans on the Solaris DB using JDeveloper and we keep getting 'peer socket disconnected errors'. I'll try the workaround which was suggestesd by the Oracle people to solve the problem and get back on this.
I don't know how Oracle will measure up to the performance when EJBs are running. But the problems mentioned above would have to be solved first.
Can anyone help out?
Thanks in advance.
Aby Philip

I can't resist a comment here. Oracle folks seem to always recommend putting the EJBs in back-end database. How many real-world enterprise-scale applications (i.e., one's that would need EJBs at all) have a non-shared back-end database? And in those cases, who in their right mind would accept running application code in the back-end database? I guess Oracle just hasn't really bought in to the concept of multi-tiered applications. The whole reason for separating the business logic tier from the EIS tier is to insulate the EIS services from the demands of the business logic code.
So from that perspective, I would highly recommend running an 8.1.7 instance in your middle tier to house your EJBs. Then you can hook up to your EIS tier either with database links, or (for better performance) by caching data in the EJB database from the EIS tier.
As for your specific issues, I can't help with the first. On issue 2, I am installing the 8.1.7.1 patch set today and I'll let you know if it fixes the JDeveloper --> Solaris deployment problem.

Corba Client For EJB

Hello
I am trying to connect Corba Client to EJB deployed in OC4J.
I followed the instructions given on
http://otn.oracle.com/tech/java/oc4j/htdocs/how-to-rmi-iiop.html
But I am not getting success after making tries in different ways.
Can some body tell how to connect to EJB by a corba client using Oc4j.
If OC4J does't support RMI-IIOP , can you suggest other server which supports that.
Thanx in advance.

I'm stuck exactly with the same issue while trying to port my application from weblogic to jboss.
I tried to specify different ORB implementations (JacORB, OpenORB) for jvm option org.omg.CORBA.ORBClass, but JBoss couldn't get them instantiated. Native Sun implementation which is used in JBoss by default and can be instantiated, apparently is not fully compatible with weblogic security module.
So did you manage to find out the solution?

Thank you for your help info, I soloved the problem.
The problem is the ejb jar was deleted(I don't why)
then System Admin to deploy EJB jar from Admin console.
After that everything is fine.

Hi Albert,
I would double check to make sure the EJB was indeed deployed (check
server log). What message did you see that leads you to believe itwas
successfully deployed? Also, verify the JNDI name you are lookingup in
your client matches the JNDI name for the EJB. If this doesn't solve
the problem, please post the error message and stack trace you are
seeing on the client.

How can I run EJB Client in other computer ?

Hello,
I'm trying to run converter examples.
if ejb client pgm resides on a same machine with j2ee server , it works fine.
But when I put client pgm on a different maching
below message show.
No application client descriptors defined for: ConverterClinet
I put ConverterApp.ear, ConverterAppClient.jar and ConverterClient.class on the machine and
set APPCPATH=ConverterAppClient.jar
set VMARGS=-Dorg.omg.CORBA.ORBInitialHost=xxx.xxx.xx.xx
What should I do to run ejb client on different machine?

Hi SangHPark,
I had the same problem but have solved it and it works.
I ran the client remotely from a win98 box.
Keep two things in mind
1> Deploy the applications to an ip address and not to the local host using the deploy too. Use the deploy tool Gui to add a new server and then deploy the application to this ip address.
2> I am running j2ee version 1.3 and jsdk 1.3
Use the following code but instead of using "java:comp/env/ejb/SimpleConverter" use the jndi name of the object: "MyConverter" as specified in the tutorial.
Properties prop = new Properties();
prop.setProperty(Context.INITIAL_CONTEXT_FACTORY,"com.sun.enterprise.naming.SerialInitContextFactory");
prop.setProperty(Context.PROVIDER_URL,"IIOP://xxx.xx.x.xxx:1050");
System.out.println("Attempting to create context...");
Context initial = new InitialContext(prop);
// Instead of this use the below line of code
//Object objref = initial.lookup("java:comp/env/ejb/SimpleConverter");
Object objref = initial.lookup("MyConverter");
// MyConverter is the Jndi name of the ConverterBean as per the tutorial
You need to do the following things.
1> After making changes to the code recompile using Ant and redeploy it.
2> Copy the j2ee.jar, ConverterAppClient.jar and ConverterClient.class file to the machine that u want to run the client from.
3> create a directory called "config" on the remote machine where you copied the files in step two.
4> Copy to this directory the files ejb.properties and security.properties from your j2ee_home\config\ directory.
For example you copied the files in step 2 on the remote machine in the c:\test directory. Create c:\test\config directory and copy the files from step 4 into this directory.
5> Run the following command from the directory where u copied the client files
java -Dorg.omg.CORBA.ORBInitialHost="host name" -classpath .\j2ee.jar;.;.\ConverterAppClient.jar ConverterClient

BC4J EJB deployment ; testing deployment to 8i with client application

Hi,
Is there a way to to connect a java client application to a 8i deployed BC4J using the oracle.dacf.dataset.SessionInfo ? Can we do this using the JDev wizards - property inspector ?
(I've seen in the doc :"Testing a Business Components EJB Deployed to Oracle8i with a Code Client" but the given code
// setup application module variable
ApplicationModule appMod = null;
javax.naming.Context ic = new InitialContext(env);
ApplicationModuleHome home = (ApplicationModuleHome)ic.lookup(DeployedMod);
appMod = home.create();
does not contains any SessionInfo object.)
Thanks,
Xvc

Chris,
Perhaps you should be checking if the user you wish to deploy
EJBs to has at least JAVAUSERPRIV.
As SYSTEM
grant JAVAUSERPRIV to <user>;
Good luck

Client of the deployed BC4j to EJB

Hi!
I have a problem, i do a deploy from my BC4j from JDev3.1 to Oracle 8.1.6 like a EJB, the problem is that i don4t know what i have to change in my client that was implement local like in the samples, and what jars i have to import in my client.
Could anyone tell me what i have to do?
Thanks, in advance.

Hi Dirk,
Following the instructions in JDeveloper and the 9iAS Administration Docu I created a .ear file
from the business components project partYou should now have a 'BC4J Configuration' (let us call 'Mypackage1ModuleOc4j2') with parameters for this iAS instance. You can test the deployment by running BC4J Tester.
1) How do I configure/create the Client (JClient) project part of the demo to use the BC4J(the EJB) deployed to the OC4J instance in the 9iAS app server ?To create a new JClient project based on the BC4J EJB deployed to this OC4J instance
1. Create a new 'Data model' and base it on the Configuration, 'Mypackage1ModuleOc4j2'.
2. Create/Modify your code and set the panel bindings.
3. Start your OC4J instance if it is not running already.
4. Run your JClient application. It will connect to the external oc4j extance.
If you want to configure an existing project to use the BC4J EJB session bean, then
right click on cpx file, modify the datamodel to use the 'Mypackage1ModuleOc4j2' configuration.
2) I want to have a 'standalone' JClient application using the BC4J deployed as Appmodule Session Bean(BMT) EJB to OC4J. How do I do this ?You can create a jar file, optionally choosing to include all dependent classes. You would get a single
jar file which you can invoke from the command line, like
java -jar <your_jar_file_name>

Hi Badri,
ApplicationClientInitialContextFactory is for clients which got deployed inside OC4J container..
For looking up EJB from a stand alone java client please use RMIInitialContextFactory..So please change ur code....
Also please check ur server.xml
Since you have specified your ejb domain as "sampledemo"
you have to use that domian only for look up..But it seems that you are looking up for "Demo" domain instead of "sampledemo" domain...So change your code to reflect that..
Code snippet for the same is :
Hashtable env = new Hashtable();
env.put("java.naming.provider.url", "ormi://localhost/sampledemo");
env.put("java.naming.factory.initial", "om.evermind.server.rmi.RMIInitialContextFactory");
env.put(Context.SECURITY_PRINCIPAL, "guest");
env.put(Context.SECURITY_CREDENTIALS, "welcome");
Context ic = new InitialContext (env);
Hope this helps

Packaging/deploying a webapp client to already deployed EJBs

I have a webapp/ejb deployed on WLS 6.1. If it matters, the EJBs are
deployed in jar files but the webapp component is deployed in exploded
directory format.
Now I want to deploy another webapp that uses the same EJBs. At this
point in development, I am attempting to deploy this in exploded
directory format as well. I have run ejbc manually against the original
jars to create the EJB deployable units containing generated WL classes.
This also created a ejb-client.jar, but it does not contain any impl
classes for the home or remoted interfaces.
I tried placing the ejb-client.jar in my WEB-INF/lib but it doesn't seem
to be able to find the interface classes. Perhaps the exception I'm
getting does not mean what I think it does. It is included below.
I also tried adding the generated impl classes to the ejb-client.jar
manually, but this didn't work either. I have read the
packaging/deploying docs but don't seem to find this issue addressed
directly. From all I know, I have done this correctly, but obviously I
am missing something somewhere.
Thanks in advance for your consideration.

Hi.
I tried placing the ejb-client.jar in my WEB-INF/lib but it >>doesn't seem to beable to
find the interface classes. Perhaps
the exception I'm getting does not mean what I think it does. >>It is includedbelow.
It seems fine since it is the way your webapp always to use its EJB client jar.
I also tried adding the generated impl classes to the ejb-
client.jar manually, but this didn't work either.Nope, you should never do this since Impl classes are used on Server Side ( webapp
treated as client of EJB in this case ) only.
It is so hard for us to analyze the problems without a test case, I would suggest
you to create a support case via http://support.bea.com/welcome.jsp to BEA support
for detailed work.
Thanks.
