本文介绍了一个使用Struts框架的应用实例，包括环境配置、所需工具包及其配置、工程创建过程等。具体涉及了JAVA_HOME、TOMCAT_HOME等环境变量设置，lomboz-emf-gef-jem-I20050521等工具包的使用，以及struts-config.xml等关键文件的内容。

1.环境变量配置：

JAVA_HOME: C:/jdk1.5.0_06

TOMCAT_HOME: C:/Tomcat 5.5

CLASSPATH: .;%JAVA_HOME%/lib/dt.jar;%JAVA_HOME%/lib/tools.jar;%TOMCAT_HOME%/common/lib/servlet-api.jar;%TOMCAT_HOME%/common/lib/jsp-api.jar;

Path: %SystemRoot%/system32;%SystemRoot%;%SystemRoot%/system32/WBEM;C:/jdk1.5.0_06/bin

2.用到的工具包：

lomboz-emf-gef-jem-I20050521,lomboz-I20050521
NLpack1-eclipse-SDK-3.1.1a-win32
struts-1.2.7
struts-console-4.8
tomcatPluginV31beta

3.工具包的配置：

　文件夹：links 文件名： lombozemfI20050521.link 内容：path=D://eclipse//lombozemfI20050521
在“设定”里配置tomcat.

4.创建工程：

1.在lib中用到的包：commons-beanutils.jar，commons-digester.jar；struts.jar

2，在WEB-INF中用到的文件： struts-html.tld，struts-config.xml，web.xml

3.各种文件的源代码：

web.xml：

<?xml version="1.0" encoding="ISO-8859-1"?>
