How to run a Client in a Jsp

I would like to run Client.java thanks to a JSP
i have got a .jar that i put in WEB-INF/lib
but that the class Client is not found

try putting your application's web-inf/lib directory in your classpath. this is typical in development environments. you wouldn't have to do it for production.
hope this helps.

How to run the client program in weblogic 8.1 server

Hi
I am new to EJB 2.0. I am deployed sucessfully a session ejb program.
While running an ejb client program it throws an exception. In my session ejb program i created two jar file. one is sessionejb.jar and another one is sessionejbclient.jar. In sessionejb.jar contains home ,remote ,session bean class and deployment descriptor.In sessionejbclient.jar contains home,remote and client program. Both jar files are included in class path of environment variable( i am using Standalone server).
Plese guide me how to run an session ejb client correctly.
Regards
Jaiganesh

Both jar files are
included in class path of environment variable( i am
using Standalone server).did u include both these jars in the "weblogic's class path" ?
in that case, it obviously wont work.
what u need is an understanding of the following topics (i have described them briefly, but for details u can always check the documentation of weblogic):
1. Class loaders in weblogic: there are various levels of class loaders. at the top is the weblogic's class loader. below it are various EARs' class-loaders. and so on....
2. Packaging. You must ensure that in the same class loader, there are not two classes from 2 different jars.
hope that helps

How to run application client of an EJB application?

Hi,
My EJB application is deployed on websphere. I have written a small java client program to interact with an EJB which is working fine if I compile and run it in websphere studio environment.
However I am getting runtime exception when I tried to run it at command line.
RemoteConn.java
import java.util.Hashtable;
import com.deque.HelloJavaHome;
import com.deque.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 name="Paruchuri!!";
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.ws.naming.util.WsnInitCtxFactory");
env.put(Context.PROVIDER_URL, "iiop://localhost:2809");
InitialContext initContext = new InitialContext(env);
Object obj = initContext.lookup("ejb/HelloJavaHome");
HelloJavaHome home = (HelloJavaHome) javax.rmi.PortableRemoteObject.narrow(obj, HelloJavaHome.class);
HelloJava remote = home.create();
greeting = remote.getGreeting(name);
catch(Exception e){
e.printStackTrace();
System.out.println("Greeting::"+ greeting);
I have set the application ejb client jar in the class path of client program.
The exception I am getting at runtime is
Exception in thread "main" java.lang.NoClassDefFoundError: com.ibm.CORBA.iiop.GlobalORBFactory

at RemoteConn.main(RemoteConn.java:38)
Initially I thought I shuold set some jar file of websphere in the classpath of client. But I did not find such a jar containing the above class in websphere studio.
Basically the error is generated at the below statement at runtime.
Object obj = initContext.lookup("ejb/HelloJavaHome");
The only difference I discovered was that the client application has a descriptor file (application-client.xml ) available to it when it ran in websphere studio,. I guess the same META-INF should be provided to client when it runs at command line.
Right now I am not using any client descriptor file to run the client program. If the above error is due to not supplying META-INF to the client application, how should I make this folder available to client at runtime?
I greatly appreciate if I could get help ASAP.
Thanks

Hey got what is going on. In order to invoke EJB, deployed on WebSpehre App Server, from application client we need to install either WebSphere Application Pluggable Client or WebSphere Thin client on the workstation. Pluggable client is a wrapper to SUN JRE where as Thin Client uses IBM JRE.

Why are you writing scriptlets and functions in JSPs?
Functions are supposed to be written in the Java Application layer.
JSPs are best suited only to display information.
Also why are you using Scriptlets insted of JSTL ?
Anyway, if you want to write in JSPs only , here's how to write a function in them: http://forum.java.sun.com/thread.jspa?threadID=496577&messageID=2341986 you can figure out the rest.

How to run a client?

A want a client progrma to connect to the server by pressing a button.
But the method to run a client is by typing:
"java HelloClient"
before run the program.
How can I call the client connection when I already run the program(an applet)?
Thanks~~

There are two concepts of being a client, the first one is to be a "storage disabled node" in the cluster which means that you are a full member of the cluster but no data is stored on your node.
To disable storage on a node, pass the following attribute on the java command line:
-Dtangosol.coherence.distributed.localstorage=falseThe second concept of a client is to use Coherence*Extend to connect to a cluster over TCP.
More details on [how to configure Coherence*Extend over here|http://wiki.tangosol.com/display/COH35UG/Configuring+and+Using+Coherence+Extend]

How to close JDBC client connections in JSP (9IDS Jdeveloper)

Can anyone tell me how to close JDBC connections neatly through JSP in Oracle 9IDS Jdeveloper.
I have a developer who has deployed a WAR file (comprising JSP page) to the Tomcat webserver.
The page works fine except that it always leaves a JDBC client connection after the user closes the internet explorer window.
I've tried using dead connection detection without success.
At the operating system level, I have a script that can kill these sessions but I would prefer if theres some way the connection can be closed neatly through the JSP application.

Hi:
At database level you can:

How to run a client program in Session bean using weblogic 8.1

Hi
I am new to weblogic server 8.1. I sucessfully deployed session ejb Session Bean. I created sessionbean jar file and put it it classpath also.
and also i created sessiobeanclient jar file, it included in class path.
While running client program it throws exception like noclass def found exception
plz tell me the right way to run the session ejb program.
bye

Hi,
You have to follow the given steps before you are going to run the client program that invokes the session bean .
1)set the Weblogic Environment using the tool setWLSEnv
2)place the Session bean jar file in classpath
3)run the client program
Note:If the client has to execute on remote machine we need to copy client class,remote interface, home interface and other classes which are used as
parameters and return types.

How to run ejb client on a separate host using Oracle example

The example I used was under $ORACLE_HOME/javavm/demo/examples/ejb/basic/jdbcimpl
If I used the Makefile provided to run the client and server, it worked ok. Now I tried to move the client to an NT machine and it did not work. (BTW, the server was on a Linux machine.)
What I did was to copy the compiled class and jar files to NT (Client.class, employee/*.class aurora_client.jar, vbjapp.jar, and vbjorb.jar). After I ran it, I got an error in javax.naming.InitialContext.lookup.
I compiled and ran the code using jdk1.1.8. If I recompiled the code on NT using jdk1.3, I got a CORBA.OBJECT_NOT_EXIST error.
Any clue?

Copy the following files to the CT's machines. Copy the server_generated.jar also to the CT's machine. In your case the file will be there in the $ORACLE_HOME/javavm/demo/examples/ejb/basic/jdbcimpl directory.
C:\ORA816\lib\aurora_client.jar;
C:\ORA816\jdbc\lib\classes111.zip; // Replace this with classes12.zip if you are using JDK 1.2.2
C:\ORA816\sqlj\lib\translator.zip; // If you are using SQLJ in the CT's code
C:\ORA816\lib\vbjorb.jar;
C:\ORA816\lib\vbjapp.jar;
server_generated.jar
Set you classpath to include the all the above files.
Oracle 8.1.6 can work with JDK 1.2.2 and JDK 1.1.8. Please try with the JDK 1.2.2 and let us know the results.

How to run different client ?

Hi,
I have downloaded and installed Oracle8i Enterprise edition Release 8.1.7.0.0.
Now I have to connect to the above server either using Oracle client version 8.1.6.3.1 or 8.1.6.2. My question is -
- is it possible to download the above version Oracle
Client ?
- how can I connect from above such client to the above
server ?
Please let me know.
Thanks,
Harish

I don't know of any site where you can still download the 8.1.6 Oracle client or database. Oracle Support may know of an FTP site for desupported products.
In general, connecting from any version of the Oracle client to an Oracle server is pretty much the same.
- You want to create a new TNS name on your client machine. This is most easily accomplished by using the Net Config Assistant (the name changes slightly between releases)
- You then connect (assuming SQL*Plus) as
connect user/password@tnsname

If stateful is the package for the client application, you should be executing from
D:\Weblogicserver\user_projects\domains\mydomain\applications\MyEJB
on the command line. The command should look like -
java -classpath <whatever should be here> stateful.MyClient

How to do a corba call in jsp ?

hello sir,
i m developing distributed application. JacORB is java orb used as middleware,
jsp and tomcat used as web interface.
i hava a difficulty how to call corba client method from jsp ?

Dear Hardikhvc,
This is the community forum for SJS Web Server, not tomcat. If you have a tomcat question, you should try to ask in the tomcat forums, you might have better luck there.
In the other hand, consider using the SJS Web Server, which is a full fledged, production quality, highly secure, industry leading web server, with a fully integrated and high performant web container. It is also free for developing purposes. More details can be found here.
