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,
use the following code to create an instance of InitialContext.
java.util.Properties properties= new java.util.Properties ();
properties.setProperty(Context.INITIAL_CONTEXT_FACTORY ,"the name of your contextFactory"
);
properties.setProperty(Context.PROVIDER_URL ,"url of your server incl. port number"
);
Context context = new InitialContext (properties);
bye
As your suggestion, I changed the code like below,
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);
Object objref = initial.lookup("java:comp/env/ejb/SimpleConverter");
...
But it didn't work through, instead I get other error message like below.
*************************************
Binding name:`java:comp/env/ejb/SimpleConverter`
Attempting to create context...
Caught an unexpected exception!
javax.naming.ConfigurationException: Invalid URL: IIOP://xxx.xx.x.xxx:1050
Root exception is java.net.MalformedURLException: unknown protocol: iiop
...
*************************************
Please guide me again..
Thank you.
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
