about this package

This example sends a "buy" or "sell" message to a JMS Topic from the Java servlet TraderServlet. The TraderReceive client receives the messages and invokes an EJBean to process the messages.

Configure the server:

To use this example, you must build and deploy the statelessSession EJB example.
Set up a connection pool as described in the About this package section for the JMS exampels package.
Set up the jmstrader servlet by adding this property to your weblogic.properties file:
```
  weblogic.httpd.register.jmstrader=examples.jms.trader.TraderServlet
```
Set the servlet classpath and reload properties in your weblogic.properties file by adding the following properties:
```
  weblogic.httpd.servlet.classpath=weblogic/myserver/servletclasses
  weblogic.httpd.servlet.reloadCheckSecs=1
```
where weblogic is the directory where WebLogic is installed.

Set up the JMS topic and connection factory by adding the following properties:

  weblogic.jms.topic.exampleTopic=javax.jms.exampleTopic
  weblogic.jms.connectionFactoryName.trader=jms.connection.traderFactory
  weblogic.jms.connectionFactoryArgs.trader=ClientID=traderReceive

Build the example:

Set up your development shell, as described in Setting up your environment.
Compile the servlet file in this directory as shown in this examples for Windows NT:
```
  $ javac -d %SERVLET_CLASSES% TraderServlet.java
```
Compile the client file in this directory as shown in this examples for Windows NT:
```
  $ javac -d %CLIENT_CLASSES% TraderReceive.java
```

Run the example:

Start WebLogic Server in a new command shell.
In your development shell, run the client with the following command:
```
  $ java examples.jms.trader.TraderReceive t3://hostname:port
```
where:

hostname
Host name of the WebLogic Server
port
Port where the WebLogic Server is listening for connections (weblogic.system.ListenPort).
Load the servlet in a browser with a URL like this:
```
  http://hostname:port/jmstrader
```
where:

hostname
Host name of the WebLogic Server
port
Port where the WebLogic Server is listening for connections (weblogic.system.ListenPort).
Enter a trade to send and click the Send button. The TraderReceive client displays messages as they are received from the Topic, and displays results from the invoked EJB.
