 <div class="id_conbody"><p class="id_shortdesc">The Java™ EE 5 programming model simplifies the
 process of creating Java applications.</p>

 <p class="anchor_topictop" />

 <p id="cjavaee5__aboutfacet"><a name="cjavaee5__aboutfacet"><!-- --></a>In the Java EE 5 specifications, programming requirements
 have been streamlined, and XML deployment descriptors are optional. Instead,
 you can specify many details of assembly and deployment with Java annotations.
 Java EE 5 will provide default values in many situations so explicitly specification
 of these values are not required.</p>

 <p>Code validation, content assistance, Quick Fixes, and refactoring simplify
 working with your code. Code validators check your projects for errors. When
 an error is found, you can double-click on it in the Problems view in the
 product workbench to go to the error location. For some error types, you can
 use a Quick Fix to correct the error automatically. For both Java source
 and Java annotations,
 you can rely on content assistance to simplify your programming task. When
 you refactor source code, the tools automatically update the associated metadata.</p>

 <p>For additional information on Java EE 5.0, see the official specification: <a href="http://jcp.org/en/jsr/detail?id=244" target="_blank">JSR 244: Java Platform, Enterprise Edition 5 (Java EE 5) Specification</a></p>

 Using the Java Platform, Enterprise Edition (Java EE) architecture, you can build distributed Web and enterprise applications. This architecture helps you focus on presentation and application issues, rather than on systems issues.</li>

 The goal of Java EE 5 platform development is to minimize the number of artifacts that you have to create and maintain, thereby simplifying the development process. Java EE 5 supports the injection of annotations into your source code, so that you can embed resources, dependencies, services, and life-cycle notifications in your source code, without having to maintain these artifacts elsewhere.</li>
