使用Eclipse开发XMLBeans项目

1. 介质准备

   　　Eclipse3.12下载地址：http://www.eclipse.org/downloads/

   　　XMLBean2.10下载地址：http://xmlbeans.apache.org/sourceAndBinaries/index.html

   　　JDK1.4+或JDK1.5+下载地址：http://java.sun.com/j2se/1.5.0/download.jsp
   注：如果使用WebLogicServer，可以不用单独安装JDK，使用产品中自带的JDK即可

1. Eclipse配置
2. 　　定义系统变量：
3. 　　%XMLBEAN_HOME%：XMLBean的安装目录
4. 　　%JAVA_HOME%：JDK安装目录
5. 　　建立Java项目

• 　　由于想使用JDK1.5，所以选择5.0，为了项目管理方便，将原代码与生成的二进制文件分开存放

  　　一定要使用JDK而不是JRE，如果默认是JRE请重新定义

  　　定义自定义用户类库，并添加所有在%XMLBEAN_HOME%/lib下的Jar包

  

  

  

  
  把xmlSchema文件加入到工程中，例如加入hello.xsd.
