This tutorial documents the J2EE 1.4 Application Server Developer Release. To build, deploy, and run the examples you need a copy of the J2EE 1.4 Application Server Developer Release and the Java 2 Software Development Kit, Standard Edition (J2SE<img src="images/tm.gif" border="0" alt="Trademarked"> SDK) 1.4.2_01 or higher. You download the J2EE 1.4 Application Server from:

Building the Examples
</h4>
<a name="wp74691"> </a><p class="pBody">
Most of the tutorial examples are distributed with a configuration file for <code class="cCode">asant</code>, a portable build tool contained in the J2EE 1.4 Application Server, that is an extension of the Ant tool developed by the Apache Software Foundation (<code class="cCode">http://www.apache.org</code>). <code class="cCode">asant</code> contains additional tasks that interact with the J2EE 1.4 Application Server adminstration utility <code class="cCode">asadmin</code>. Directions for building the examples are provided in each chapter. 
</p>
<a name="wp74692"> </a><p class="pBody">
In order to run the <code class="cCode">asant</code> scripts, you must configure your environment and properties files as follows:
</p>
<div class="pSmartList1"><ul class="pSmartList1">
<a name="wp74693"> </a><div class="pSmartList1"><li>Add <code class="cCode">&lt;</code><code class="cVariable">JAVA_HOME</code><code class="cCode">&gt;/bin</code> to the front of your path.</li></div>
<a name="wp74694"> </a><div class="pSmartList1"><li>Add <code class="cCode">&lt;</code><code class="cVariable">J2EE_HOME</code><code class="cCode">&gt;/bin</code> and <code class="cCode">&lt;</code><code class="cVariable">J2EE_HOME</code><code class="cCode">&gt;/share/bin</code> to the front of your path so that J2EE 1.4 Application Server scripts (<code class="cCode">asadmin</code>, <code class="cCode">asant</code>, <code class="cCode">deploytool</code>, and <code class="cCode">wscompile</code>) override other installations.</li></div>
<a name="wp74695"> </a><div class="pSmartList1"><li>Set the <code class="cCode">j2ee.home</code> property in the file <code class="cCode">&lt;</code><code class="cVariable">INSTALL</code><code class="cCode">&gt;/j2eetutorial14/examples/common/build.properties</code> to the location of your J2EE Application Server installation. The build process uses the <code class="cCode">j2ee.home</code> property to include the J2EE library archive, <code class="cCode">&lt;</code><code class="cVariable">J2EE_HOME</code><code class="cCode">&gt;/lib/j2ee.jar</code>, in the classpath. If you wish to use an IDE or the <code class="cCode">javac</code> compiler to build J2EE applications, you must add this JAR to your classpath. </li></div>
</ul></div>
<hr>
<a name="wp75453"> </a><p class="pNote">
Note: On Windows, you must escape any backslashes in the <code class="cCode">j2ee.home</code> property with another backslash or use forward slashes as a path separator. So, if your J2EE 1.4 Application Server installation is <code class="cCode">C:\Sun\AppServer</code>, you must set <code class="cCode">j2ee.home</code> as follows:<br /><br /><code class="cCode">j2ee.home = C:\\Sun\\AppServer <br /><br /></code>or<br /><br /><code class="cCode">j2ee.home=C:/Sun/AppServer</code>

Tutorial Example Directory Structure
</h4>
<a name="wp67543"> </a><p class="pBody">
To facilitate iterative development and keep application source separate from compiled files, the source code for the tutorial examples is stored in the following structure under each application directory:
</p>
<div class="pSmartList1"><ul class="pSmartList1">
<a name="wp67544"> </a><div class="pSmartList1"><li><code class="cCode">build.xml</code>--<code class="cCode">asant</code> build file</li></div>
<a name="wp67545"> </a><div class="pSmartList1"><li><code class="cCode">src</code>--Java source of servlets and JavaBeans components, and tag libraries</li></div>
<a name="wp67546"> </a><div class="pSmartList1"><li><code class="cCode">web</code>--JSP pages and HTML pages, tag files, images</li></div>
</ul></div>
<a name="wp67689"> </a><p class="pBody">
The <code class="cCode">asant</code> build files (<code class="cCode">build.xml</code>) distributed with the examples contain targets to create a <code class="cCode">build</code> subdirectory and copy and compile files into that directory and perform administrative functions on the application server. Build properties and targets common to a particular technology are specified in the files<code class="cCode"> </code><code class="cCode">&lt;</code><code class="cVariable">INSTALL</code><code class="cCode">&gt;/j2eetutorial14/examples/</code><code class="cVariable">technology</code><code class="cCode">/common/build.properties </code>and <code class="cCode">&lt;</code><code class="cVariable">INSTALL</code><code class="cCode">&gt;/j2eetutorial14/examples/</code><code class="cVariable">technology</code><code class="cCode">/common/targets.xml</code>.
