Porting and Deploying Smart Ticket with WebLogic Builder

This example shows a rapid deployment scenario for Sun's BluePrint wireless application, Smart Ticket. We use WebLogic Builder to generate and edit the WebLogic Server-specific deployment descriptor files and to deploy the application on WebLogic Server.

WebLogic Builder is a visual environment for generating and editing an application's deployment descriptor files. You can view descriptor files while you visually edit them in WebLogic Builder, and you won't need to make textual edits to the XML. See WebLogic Builder.

This document contains following sections:

• Setting Up Applications and Environment

  • Download and install WebLogic Server 7.0

  • Download and install Smart Ticket

  • Download and install the Sun Wireless Toolkit

  • Set your environment

  • Build Smart Ticket

• Converting and Tuning with WebLogic Builder

  • Use WebLogic Builder to generate weblogic.xml and weblogic-ejb-jar.xml

  • Use WebLogic Builder to edit descriptors

• Administration Tasks

  • Start server (WebLogic Server's Examples server)

  • Use WebLogic Server Administration Console to configure datasources

  • Modify populate.bat script and SQL query to use the Pointbase sample database

  • Use WebLogic Builder to deploy Smart Ticket

  • Launch Smart Ticket.

  • Query and write to the datasources to create a user account and reserve movie tickets.

Setting Up Applications and Environment

You'll need the following to run this example.

• WebLogic Server 7.0

• Smart Ticket

• Sun's wireless toolkit, J2ME

• smarticketPointBase.sql (attached)

Here are the installation and build tasks and the path-settings you'll need.

1. Download and install WebLogic Server 7.0.

   Download WebLogic Server 7.0 from http://www.bea.com and install it to a location we will hereafter call WL_HOME. By default, WL_HOME is c:\bea\weblogic700.

2. Download and install Smart Ticket 1.1.

   Download the Smart Ticket demo application source code at : http://developer.java.sun.com/developer/releases/smarticket/. Extract it into a new directory on your machine. We will call this directory SMARTICKET_HOME.

3. Download and install J2ME to a location we will call J2MEWTK_HOME (default: C:\J2mewtk).

   Download the Sun Wireless toolkit at: http://java.sun.com/products/j2mewtoolkit/download.html. Install the toolkit. During installation you will be prompted to select a JDK. You can select the JDK included in your BEA_HOME/jdk131 directory.

4. Set J2MEWTK_HOME=C:\J2mewtk, assuming C:\J2mewtk is where you installed J2ME. Note: if you do not set J2MEWTK_HOME, you will not be able to build the application.

5. Set your environment by running the setExamplesEnv script located in WL_HOME\samples\server\config\examples.

6. To SMARTICKET_HOME \smarticket\localant.bat, add "%CLASSPATH%" to the end of the ANT_CLASSPATH line.

7. Change to the SMARTICKET_HOME\smarticket directory and build Smart Ticket by running localant.bat . WebLogic Builderrequires compiled .class files and cannot use .java files.

Converting and Tuning with WebLogic Builder

In this section, WebLogic Builder generates deployment descriptors, and we edit some of them without having to look at any XML.

Generating Descriptors

In this sequence, WebLogic Builder reads the existing descriptor files and introspects the application's .class files to create the deployment descriptor files that help an application to run on WebLogic Server.

Note that WebLogic Builder will not overwrite the application's existing deployment descriptor files.

1. Open WebLogic Builder from Start | Programs | BEA WebLogic Platform | WebLogic Server 7.0 | WebLogic Builder.

2. In WebLogic Builder's File | Open menu, navigate to SMARTICKET_HOME \build\server and click Open. A dialog asks: "Unable to locate deployment descriptors. Would you like deployment descriptors created for you?" Click Yes, and WebLogic Builder will introspect the Smart Ticket class files and generate weblogic.xml and weblogic-ejb-jar.xml.

3. Select File | Save and save the application in WebLogic Builder.

4. In WebLogic Builder, create smarticket.ear by selecting File | Archive and specifying SMARTICKET_HOME \bin\smarticket.ear.

5. Start the Examples server from: Start | Programs | BEA WebLogic Platform | WebLogic Server 7.0 | Server Tour and Examples | Launch Examples Server. The Examples Server launches a WebLogic Server Examples page.

6. Open the WebLogic Administration Console by navigating to http://localhost:7001/console (or by following the link from the WebLogic Server Examples page), and sign in using username weblogic and password weblogic.

Specifying JNDI Names and <context-root>

In this sequence, we use WebLogic Builder to:

• Set the web application's context path

• Assign JNDI names to the web application's EJB references and resource references

• Assign JNDI names to the EJB resource references

1. In WebLogic Builder, select the \web node's Context Path tab. In the Context Path text field, enter SmarTicketApp. Now the <context-root> element is set.

2. Select Builder's EJB Refs panel in the J2EE Refs node, and specify the JNDI names for the EJB Refs as follows: boo

Reference Name	EJB Type	JNDI Name
ejb/MovieInfo	Session	MovieInfo
ejb/TicketSales	Entity	TicketSales
ejb/Customer	Entity	Customer
ejb/LocaleInfo	Session	LocaleInfo

3. Select the Resource Refs panel in Builder's J2EE Refs node and set the Ref Name, EJB Type, and JNDI Name as in the table below. Set the Resource Authentication Type to Container.

4. Select the Resource References panel from Builder's EJB Resources node and set JNDI names for EJB Resources as in the table below.

5. Use Builder's File | Save to save changes to the archive.

Administration Tasks

In this section we :

• Use the WebLogic Server Administration Console to configure the data sources

• Convert to the Pointbase example RDBMS.

Configuring Data Sources

Now we use the WebLogic Server administration console to configure the Data Sources for each of the four EJBs the Smart Ticket application uses.

1. If you haven't already started the WebLogic Examples Server and opened the Administration Console by pointing a browser to http://localhost:7001/console, do so now.

2. Select the JDBC node and click Tx Data Sources.

3. Select Configure a new JDBC Tx Data Source.

4. Enter a name for the data source. The first one is MyCustomerDataSource. Enter CustomerDataSource in the JNDI field. Enter demoPool as your Pool Name; this is the default connection pool that WebLogic examples use. Click Create.

5. Click the Targets Tab, then select the examplesServer in the Available column and click on the right arrow to target it. Click Apply.

6. Repeat steps 4 and 5 for the other four data sources (MyMovieInfoDataSource, MyLocaleInfoDataSource, and MyTicketSalesDataSource).

7. To replace Smart Ticket's Cloudscape database with Pointbase, the evaluation RDBMS included with WebLogic Server 7.0, just add the following to SMARTICKET_HOME \smarticket\populate.bat:

   set POINTBASEHOME=%SAMPLES_HOME%\server\eval\pointbase 

   java utils.Schema jdbc:pointbase:server://localhost/demo,database.home=%POINTBASEHOME% com.pointbase.jdbc.jdbcUniversalDriver -u examples -p examples -verbose ./src/smarticketPointBase.sql

8. We are also making the smarticket.sql Pointbase friendly by replacing it with a script that substitutes "int" data types with "integer." Copy smarticketPointBase.sql from into SMARTICKET_HOME \smarticket\src .

9. Set up the database by running populate.bat.

Deploying and Running

Now we are ready to deploy and run Smart Ticket on WebLogic Server 7.0.

1. Connect to the server using the Connect to Server dialog in Weblogic Builder's Tools menu.

   
    

   Figure 0-2 Connecting to the Examples Server

2. Deploy Smart Ticket by selecting Deploy Module from the WebLogic Builder tools menu.

3. Set the port in SMARTICKET_HOME\bin\smarticket.jad by replacing the given port number (8000) with the port number of the Examples server, which by default is 7001.

4. Start SMARTICKET_HOME\bin\smarticket.jad by double-clicking it or by selecting Start | J2ME Wireless Application | Run MIDP Application and selecting it:

   

5. You are running the Smart Ticket application on the Examples Server.

   

Running the Wireless Application

When creating a user account for the SmartTicket Application, enter in 95130 or 95054 for your zip code; also, your password must be 6 characters long. Try selecting the 'Poster' mode when you create an account; this will enable your phone or emulator to view a picture of the movie you choose to see.

There are several options available for using the emulator. Go into your J2ME Wireless Ticket and manipulate the default device and preferences.

If you have run the client Smart Ticket Application before and are redeploying the application on WebLogic, you will have to clear the database of the previous users information. To do so, run the J2ME Wireless Ticket Utility which is available from the Windows start menu. Click on 'Clean Database'. Then restart the Smart Ticket Client.

Summary

We downloaded the Sun application, built it, and usee WebLogic Builder to generate the weblogic.xml and weblogic-ejb-jar.xml files required to run it on WebLogic Server. We then edited the application's elements slightly using WebLogic Builder, and used the WebLogic Server Administration Console to configure the application's datasources. We used WebLogic Builder to deploy the application, which we then launched and ran.
