Server Tomcat v6.0 Server at localhost was unable to start within 40 seconds.

服务器启动超时，有可能是因为启动这个服务时，需要加载的东西太多了，这种情况就可以将启动超时设置的长一点。

做法是，将这个webProject 所在的workplace路径，如：E:\.metadata\.plugins\org.eclipse.wst.server.core\servers.xml。找出servers.xml文件里面的 start-timeout参数

<server auto-publish-setting="2" auto-publish-time="1" configuration-id="/Servers/Tomcat v6.0 Server at localhost-config" hostname="localhost" id="Tomcat v6.0 Server at localhost" name="Tomcat v6.0 Server at localhost" runtime-id="Apache Tomcat v6.0" saveSeparateContextFiles="true"
server-type="org.eclipse.jst.server.tomcat.60" server-type-id="org.eclipse.jst.server.tomcat.60"
start-timeout="40" stop-timeout="15" testEnvironment="false" timestamp="31">

可以把start-timeout="40"改做80.
