IDEA15.0.2 在tomcat运行maven项目时出现如下错误

Question

这个是OutPut

C:\apache-tomcat-8.0.30\bin\catalina.bat run
[2016-01-08 10:25:30,688] Artifact zhaowoba-web:war exploded: Server is not connected. Deploy is not available.

错误: 找不到或无法加载主类 SET
Disconnected from server

这个是Eventlog
10:25:31 Application Server was not connected before run configuration stop, reason:

     java.io.IOException: Failed to retrieve RMIServer stub: javax.naming.CommunicationException [Root exception is java.rmi.ConnectIOException: error during JRMP connection establishment; nested exception is:
