about this package

The examples in this package show how to set up JMS objects for access to JMS Queues and Topics and how to send and receive messages.

To use the examples, set up a JDBC connection pool for JMS and register example Queues and Topics in the weblogic.properties file.

When you use JMS with EJBeans together in transactions, both must use the same JDBC connection pool. The following properties define a Cloudscape JDBC connection pool and tell JMS to use that pool:

  weblogic.jdbc.connectionPool.demoPool=\
        url=jdbc:cloudscape:demo,\
        driver=COM.cloudscape.core.JDBCDriver,\
        initialCapacity=1,\
        maxCapacity=5,\
        capacityIncrement=2
	props=user=none;password=none;server=none

  weblogic.allow.reserve.weblogic.jdbc.connectionPool.demoPool=everyone

  weblogic.jms.connectionPool=demoPool

The TraderServlet and TraderReceive examples use an EJBean and a durable subscription. To set up the durable subscription for this example, create a connectionFactory with the following two properties:
```
  weblogic.jms.connectionFactoryName.trader=weblogic.jms.connectionFactory
  weblogic.jms.connectionFactoryArgs.trader=ClientID=traderReceive
```
You must also build and deploy the statelessSession EJB example to use the Trader JMS examples.
The SenderServlet.java example is an HTTP Servlet that allows you to send messages to the example Topic or Queue from a browser. The TraderServlet example sends "buy" and "sell" orders to the example Topic for use with the TraderReceive example. Add the following properties to weblogic.properties to make the servlets available from your WebLogic Server:
```
  weblogic.httpd.register.jmssender=examples.jms.sender.SenderServlet
  weblogic.httpd.register.jmstrader=examples.jms.trader.TraderServlet
```

There are additional instructions on the pages for the examples.
