　　用Eclipse 开发web项目，用ant编译程序，并weblogic 在启动时不能自动部署web应用程序，在手动部署时出现下面的提示：

####<2006-10-27 下午13时24分51秒 CST> <Error> <Deployer> <d28afb45b2fd498> <myserver> <ExecuteThread: '3' for queue: 'weblogic.kernel.System'> <<WLS Kernel>> <> <BEA-149201> <Failed to complete the deployment task with ID 0 for the application  WebApp

在网上用google搜了下，说是“编译时用的jdk和weblogic用的jdk不是一个版本，用一个版本就好了”，试试吧，我修改了项目编译时用的jdk。具体步骤如下

1.右击项目选择properties。点击左侧的java Compiler，
2.在右侧会看到 Configure Workspace Settings...,点击它
3.修改右侧的Compiler Compliance level  的jdk版本就OK!
