unable to start within 45 seconds. If the server requires more time, try increasing the timeout in the server editor

eclipse启动项目时，提示超时：

解决方案：

修改 workspace.metadata.pluginsorg.eclipse.wst.server.coreservers.xml文件。 
<servers> 
<server hostname="localhost" id="JBoss v5.0 at localhost" name="JBoss v5.0 at 
localhost" runtime-id="JBoss v5.0" server-type="org.eclipse.jst.server.generic.jboss5" 
server-type-id="org.eclipse.jst.server.generic.jboss5" start-timeout="1000" stop- 
timeout="15" timestamp="0"> 
<map jndiPort="1099" key="generic_server_instance_properties" port="8090" 
serverAddress="127.0.0.1" serverConfig="default"/> 
</server> 
</servers> 
把 start-timeout="45" 改为  start-timeout="1000" 或者更长 
重启eclipse就可以了。
