Answer 1

应该是你的server 启动的时间设置太短了，把时间设置大点，
(1)第一种方法： 你点击打开server，找到右边有个属性设置的，->timeout->这里设置时间
（2）mxl的话
1.<PRE class=xml name="code"><?xml version="1.0" encoding="UTF-8" standalone="no"?>
2.<servers>
3. <server auto-publish-setting="2" auto-publish-time="1" configuration-id="/Servers/Tomcat v7.0 Server at localhost-config" deployDir="wtpwebapps" hostname="localhost" id="Tomcat v7.0 Server at localhost" name="Tomcat v7.0 Server at localhost" runtime-id="Apache Tomcat v7.0" server-type="org.eclipse.jst.server.tomcat.70" server-type-id="org.eclipse.jst.server.tomcat.70" start-timeout="45" stop-timeout="15" testEnvironment="true" timestamp="5">
4. <list key="modules" value0="cbsProject_comm::org.eclipse.jst.jee.server:cbsProject_comm::jst.web::3.0"/>
5. </server>
6.</servers>
7.</PRE>
