Server JBoss v5.0 at localhost was unable to start within 50 seconds. If the server
requires more time, try increasing the timeout in the server editor.
解决办法:
修改 workspace\.metadata\.plugins\org.eclipse.wst.server.core\servers.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="50" 改为 start-timeout="1000"
重启eclipse就可以了。
其它原因：
我的是因为先前把端口号改为8090，而忽略其他地方的修改，这次我把
C:\jboss-5.0.0.GA\server\default\deploy\jbossweb.sar里面下的server.xml下的相应处也改过
来了即protocol="HTTP/1.1" port="8090"。重启eclipse就可以了，否则Eclipse老在那里work building。
