请教高手配置j2ee问题：
我用tomcatPluginV3 ＋ lomboz.3rc2＋emf-sdo-runtime-I200406100948 ＋ eclipse-SDK-3.0-win32.zip 配置的j2ee环境。服务器用的是jakarta-tomcat-5.0.28 ,在eclipse 的工具栏中启动tomcat正常。
但是我建了一个lomboz j2ee project 用下图（请看下面的方式检查jsp 语法，然后run server 但是出错，错误如下：

但是show in Browse时还能正常显示Welcome.
还请那位高人指点迷津,为什么在run server时会有异常发生。
