以前我用eclipse+lomboz+jboss用的好好的
今天想换用Tomcat
我装了Tomcat5.0和Tomcat的eclipse插件，Prefernce里也设置了Tomcat的选项
新建了一个Lomboz J2EE工程，里面放了一个Web Module，服务器选的Tomcat5.0.x
运行一个最简单的根据html页面用户提交的一个整数输出一定行"Hello，World!"的JSP
那个HTML页面显示正常，但是以提交需要输出"Hello，World!"的次数就出错：请问这是怎么回事呀！！！2006-5-21 22:27:14 org.apache.jasper.compiler.Compiler generateClass
