JDK1.2 client to EJB in Oracle8.1.6

I had my EJB client (JDK1.1.8) with my EJBs (in Oracle8.1.5) all worked before.
After I deployed the same EJBs (with SQLJs) into Oracle8.1.6, my EJB client (JDK1.2.2)
was able to connect and using the EJB sevices.
However, I got some strange behavior which never occurd with JDK1.1.8 and Oracle8.1.5.
I will sometimes get exception for calling the remote method as,
Exception in thread "main" org.omg.CORBA.COMM_FAILURE:
java.net.SocketException:Connection shoutdown:
JVM_recv in socket input stream read minor code: 0 completed: No
at com.visigenic.vbroker.orb.TcpConnection.read(TcpConnection.java, Compiled Code)
at com.visigenic.vbroker.orb.GiopConnectionImpl.receive_message(GiopConnectionImpl.java:436)
This normally occured after several calls. But it does not always happen.
Any suggestions?

Sorry, the problem still exists. If I repeated calling all the methods
in my EJB from the EJB client, I will eventually get the
"Peer disconnected socket" error.
Please let me know what could be the reason.
Thanks for any help.

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.

Running the client in ejb

i have written code for the following.
*Remote Interface
*Home Interface
*Stateless SessionBean
*Client Program
how do i run the client program. Im using a jboss application server. what files should be kept in which folder to run the program...

Verify if the connect.properties match your deployment mode viz Local, EJB or Oracle8i.

Using the 9i client's provider towards Oracle8i

Will the OraOLEDB provider supplied in the Oracle9i client function towards an Oracle8i server?
And do I gain anything from it: Is the Oracle9i provider more stable, or more feature-rich, even towards an Oracle8i server?
Thanks for any answer.

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?

Restrict number of simultaneous connection from client to EJB bean

I have EJB bean and JavaSE client. I want to restrict number of simultaneous connection from client to EJB bean. For example to maximum allowed 3. How I can do it?

:) but answer is too general.
I want to know how to design such "simple reference counting". As I understand it is not recommended to use static variables in EJB. so how to implement such counting in a right way?

Ejb client to ejb communication- slow performance ?

I think BEA has a very nasty implementation of ejb client to ejb server communication.
When a client looks up a an ejb component it gets a t3client eastablishing a socket connection to the ejb server (WL server).
For one client VM there is one such client and all ejb client to server packets go through this one socket. To me it seems to be a major bottleneck for performance.
Any body has any info ideas on how to get around this.

What makes you think it's a bottleneck? It nearly always greatly improves performance.

Rmi-iiop client for EJBs

I've been fighting the same issues over the past few days. The answer you gave still left me
wondering which tool to use. Should it be rmi -iiop or ejbc -iiop? I get the idl files on
WLS 5.1 generated but then I can't get the idlj to execute properly on the generated
HelloHome.idl and Hello.idl.

Client in ejbs

explain the term client in ejbs ? where do we install a client on the server? If the client is a standalone program how i user like me can use the client? explain briefly where this client is used in enterprise applications? I got the doubt because a standalone program is compiled into a class file. As a user how i know what is there in client program?
I am the student learning j2ee Please help me in this regard
Thank You

A client is a standalone program or a web interface that connects to the
server your business logic (written using the EJB technology) runs. Take a
web shop for instance. The web interface is the client. When you order
something, the web interface connects to the server, passes the data,
waits for the result to be returned and displays the result (e.g. one more
item in the cart, higher total and so on).
When you want a web client, you have to deploy a WAR file that contains all
the stuff that is needed (JSPs, Beans, deployment descriptor, ...).
If it is a standalone program, you use it like every other program. You start
it using java -jar client.jar. This program contains some libraries that
enables it to connect the server if needed.
You as a user know that there is a client as you just use it. You may not now
that there is an EJB backend.

How to create a WEB client in EJB module in NB 4.1 ?

hi
I am using SUN AS and NB 4.1
I want to invoke a WS from an EJB. For some reason NB 4.1 doesn't allow me to create a WS client. Why ?

netbeans forum may prove to be more useful because
this seems to be a netbeans specific problem; an EJB
can be a WS client and this works as is evident with
the Adventure Builder sample app from blueprintsI generated WS stub manually without NB 4.1.

Creating multiple stateful session beans from a java client. (EJB 3.0)

I'm having difficulties with the following:
To access the ShoppingCartBean, I have to put the following annotation in my standalone java client:
@EJB
private static ShoppingCartRemote shoppingCartBean;
The static must be there, thus only one ShoppingCartBean will exist within my java client. But as the ShoppingCartBean is a stateful session bean, I want to be able to get different beans of the same type.
What is the correct way to do this in EJB 3.0?

Great question. Because Home interfaces have been removed for the EJB 3.0 simplified
API, stateful session bean creation happens as a side-effect of injection. However, the
same is true of EJB 3.0 business interface lookups. The easiest way to create additional
stateful session beans is to lookup the same dependency that was declared via your
@EJB annotation.
E.g.,
// Assuming the declaring class is pkg1.ShoppingCartClient.java
InitialContext ic = new InitialContext();
ShoppingCartRemote scr1 = (ShoppingCartRemote)
ic.lookup("java:comp/env/pkg1.ShoppingCartClient/shoppingCartBean");
Note that the name relative to java:comp/env is the default associated with your
@EJB annotation since the name() attribute wasn't used. Alternatively, you
could have used :
@EJB(name="scb") private static ShoppingCartRemote shoppingCartBean;
InitialContext ic = new InitialContext();
ShoppingCartRemote scr1 = (ShoppingCartRemote) ic.lookup("java:comp/env/scb");
Yet another alternative is to declare the @EJB at the class-level. This just defines
the dependency without any injection, which is fine if you want to create a bunch of
them via lookup anyway.
@EJB(name="scb", beanInterface=ShoppingCartRemote.class)
public class .... {

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.
