Compiling and packaging your application

Now that I have shown all the code to the CMP enabled entity bean, let s look at how to

package and actually deploy it. To facilitate deployment, I have created an Ant build

script that does the following:

compiles all of the source code

packages the enterprise beans into two

.jar

files: one for the session bean

(

userMgmt.jar

) and one for all of the entities (

userEntity.jar

)

packages the client code into a

.jar

file (

client userMgmt.jar

)

Uses SQL DDL to create sample database tables

Packages the

.jar

files into an

.ear

file (

app.ear

)

Note that an

.ear

file is an Enterprise Archive file. Basically it is a file that can contain

other

.jar

files and

.war

files.

Ear

files can be read and processed by using the version

of

deploytool

that ships with the reference implementation.

The to compile and package your application you will need to setup your environment.

Setup you environment as follows:

set USR_ROOT=c:

set JAVA_HOME=%USR_ROOT%\jdk1.3

set J2EE_HOME=%USR_ROOT%\j2sdkee1.3

set ANT_HOME=%USR_ROOT%\tools\Ant

PATH=%PATH%;%ANT_HOME%\bin;%J2EE_HOME%\bin

The above example assumes you are using a Windows box and that you have installed

the Java SDK in

c:\jdk1.3

, the J2EE SDK in

c:\j2sdkee1.3

and that you have installed

the Ant build application in

c:\tools\ant

. Create a batch file similar to the one listed

above and adjust the directory location accordingly. Modification will have to be made

for developers on other platforms. (I expect any Unix jocks to translate the above easily

into thier shell script of choice so I wont insult thier intelligence by adding directions.)

Deploying your application with

deploytool

To run the Ant build script go to cmpCmr/seciton2 and type

ant package

on the

command prompt. Using Ant with no arguments will display a message describing all of
