eclipse 运用小结

1：怎么样把一个完整的项目导入到eclierver Tomcat v6.0 Server at localhost was unable to start within 45 seconds
pse中？

     方法一： 在MyEclipse中或Eclipse导入工程，可以通过Eclipse中的菜单File→Import→Existing Projects intoWorkspace中选择Project；

   方法二：把你的工程整个文件夹直接贴到Windows工作区的文件夹下;
然后打开MyEclipse或Eclipse,新建工程取和你的工程一样的名字OK,就导进来了.

2:The import javax.servlet.RequestDispatcher cannot be resolved等等

The   import javax.servlet.* cannot be resolved

找到%tomcat%\common\lib目录下的servlet-api.jar，把这个jar添加到%java_home%/\jdk1.6.0\jre\lib\ext目录下面，不同的jdk版本都一样。如果还不行，把servlet-api.jar拷贝到工程的lib下，Referenced Libraries->Build path ->add  JARS

3：Server Tomcat v6.0 Server at localhost was unable to start within 45 seconds. If the server requires more time, try increasing the timeout in the server editor.

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="45" 改为  start-timeout="1000" 或者更长
