Step-By-Step How to deploy Session Bean from Weblogic 5.1.0 samples into IBM WebSphere 3.5

This topic shows you step-by-step how to deploy session bean from Weblogic 5.1.0 to IBM WebSphere 3.5 samples and run a client for it. The sample resides in %WL_HOME%\examples\ejb\basic\statelessSession.

Creating a project and changing CMP bean

Copy all *.java files from %WL_HOME%\examples\ejb\basic\statelessSession to %TG_HOME%\myprojects\session\examples\ejb\basic\statelessSession.
Start Together.
Create a New Project and set its location to %TG_HOME%\myprojects\cmp. Enter 'cmp' as the project name. As you won't need standard libraries, remove them from the project: press Advanced button, select Search Classpath and make sure that checkboxes 'Include standard libraries' and 'Include Classpath' are cleared. On the EJB tab select IBM WebSphere AE 3.5 server. Press OK.
Navigate to statelessSession node in the Explorer, choose Open Diagram on its speedmenu and open statelessSession package.
Select TraderBean in the diagram in the diagram, choose Properties from its speedmenu and open Object Inspector..
Select 'Session EJB' page and in the Properties tab set JNDI name to "TraderHome".
Close Object Inspector.
Edit constructor 'ejbCreate()':

Find

Replace

try {
InitialContext ic = new InitialContext();
Integer tl = (Integer) ic.lookup("java:/comp/env/tradeLimit");
tradeLimit = tl.intValue();
}
catch (NamingException ne) {
throw new CreateException("Failed to find environment value "+ne);
}

tradeLimit = 300;

You are now ready to deploy this bean to WebSphere 3.5

Correcting the Client

Select Client class on the diagram.
Edit JNDI_NAME parameter:

Find

Replace

private static final String JNDI_NAME = "statelessSession.TraderHome";

private static final String JNDI_NAME = "TraderHome";

Edit main() method:

Find

Replace

String url = "t3://localhost:7001";

String url = "iiop://localhost:900";

Edit getInitialContext method:

Find

Replace

h.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory")

h.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.ejs.ns.jndi.CNInitialContextFactory")

The client is now ready.

Deploying the Bean

Precondition

Start WebSphere server:

Select Control panel | Services from Start | Settings menu.
Select "IBM WS AdminServer" and press Start button.

Note: "IBM HTTP Administration" and "IBM HTTP Server" should be already started.

Deploying the bean

Run Together 's Main Menu | Tools | EJB Deployment Expert
Select "IBM WebSphere AE 3.5" as the target server and make sure that all available checkboxes, except "Process servlets", "Generate WLM jar for Bean","Generate start and compile file for client" and "Generate simple JSP client" are set. Press Next.
Set paths to WebSphere home directory and to IBM JDK 1.2.2 root directory (e.g. "c:\WebSphere\AppServer" and "c:\WebSphere\AppServer\jdk"). Press Next.
Set the following parameters on the next page:

Parameter name

Setting

Comment

Admin Node Name

Name of the Node to deploy

Name of the computer

Dependent ClassPath

Fully qualified path to WebSphere

Check if it refers to existing jars

Application Server Name

Your Application Server

"Default Server" by default

EJB Container name

Your Container name

"Default Container" by default

Target WebSphere server directory

WebSphere home directory

e.g. c:\WebSphere\AppServer

Launch server in debug mode

OFF

Press Next and Finish.

If you have checked Hot Deploy check box, the last message in the Message Pane should be:

//WAS35: Finished with 0 Errors, 0 Warnings.

It means the deployment process successfully completed. Now let us create a client for this bean.

Compiling and running the client

Add the following libraries to your project:

%WAS_HOME%\jdk\jre\lib\ext\rmiorb.jar
%WAS_HOME%\jdk\jre\lib\ext\iioprt.jar
Deployed jar file (e.g. %WAS_HOME%\deployableEJBs\DeployabletogetherEJB.jar)
Home directory of WebSphere Server %WAS_HOME%

This is done in the following way

From the Main Menu | File | Project Properties dialog select Search/Classpath page on the Resource pane. At this moment there shouldn't be anything added to the classpath.
Press Add Zip/JAR button and add %WAS_HOME%\jdk\jre\lib\ext\rmiorb.jar, %WAS_HOME%\jdk\jre\lib\ext\iioprt.jar
Press OK to save project properties.
Select Main Menu | Options | Project
Go to the Tools tab and add Deployed jar file to the ClassPath.

Note: In the nearest builds these libs will be added automatically.

Select Main Menu | Options | Project and set JDK Home to %WAS_Home%\jdk on the Tools Tab. Press "OK"
- Select 'Client' class on the diagram and choose Rebuild Node on the speedmenu.
- Builder pane displays a message that the tool is completed.
- Select Main Menu | Tools | Run/Debug | Run. Make sure that 'Class with main' is set to examples.ejb.basic.containerManaged.Client. Press OK.
- The following messages appear in the Runner pane:
