weblogic部署应用时因class文件版本不正确的解决办法

本次出差到北京，完成公司的一个信贷项目，由于这个项目是以前的老项目，JDK的版本是1.4，所以不得不用weblogic8.1作为应用服务器进行部署调试了，但当我从svn服务器上拿下源码，编译运行时报了如下错误：

The WebLogic Server did not start up properly.

看完错误日志可以肯定是java的版本问题，要解决这个问题，通过如下几步：

1、检查Eclispe默认的JDK版本是否为1.4，检查办法：window-->preferences-->java-->compiler

2、在window-->preferences-->java-->installed jres下找到1.4的jre，加载并选中

3、在Eclipse中配置weblogic时，一定也要选择JDK，如下图：
