String realPath = httpServletRequest.getSession().getServletContext()
				.getRealPath("");
String realPathtem = ResourceLoader.getWepAppRootPath(httpServletRequest.getSession().getServletContext());
String path=this.getClass().getClassLoader().getResource("/").getPath();
URL u = httpServletRequest.getSession().getServletContext().getResource("/");
String  weblogic_path=u.getPath();

realPath[null]
realPathtem[/app/oracle/product/11.2.0/db_1/jlib/]
path[/app/Oracle/Middleware/user_projects/domains/tdms/servers/AdminServer/tmp/_WL_user/tdms/m76978/war/WEB-INF/classes/]
weblogic_path[/app/Oracle/Middleware/user_projects/domains/tdms/servers/AdminServer/tmp/_WL_user/tdms/m76978/war/]

 发布应用程序出现问题：

错误描述：

VALIDATION PROBLEMS WERE FOUND problem: cvc-enumeration-valid: string value '3.0' is not a valid enumeration value for web-app-versionType in namespace http://java.sun.com/xml/ns/javaee:<null>

解决方法：

weblogic11g并不支持web-app_3_0.xsd的定义，所以出错

将war包中web.xml文件的头作如下修改

<web-app xmlns="http://java.sun.com/xml/ns/javaee"

  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

                      http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"

  version="3.0"

  metadata-complete="true">

  修改为：

<web-app version="2.5" 

    xmlns="http://java.sun.com/xml/ns/javaee" 

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 

    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 

    http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
