omittestcase.java

Java有关XML编程需要用到axis 的源代码 把里面bin下的包导入相应的Java工程 进行使用

/**
 * OmitTestCase.java
 *
 * This tests the omitting of elements when minOccurs=0 and the value 
 * of the element is Null.
 * 
 * For instance:
 *  <Phone>
 *   <prefix>555</prefix>
 *   <number>1212</number>
 *  </Phone>
 *
 * This would normally have the additional areaCode element: 
 *   <areaCode xsi:nil=true/>
