我这个jsp在单独tomcat下运行没错误
但是在jbuilder下编译同不过
提示"LoginIn.jsp": Error #: 202 : 'class' or 'interface' expected
怎么回事啊？谢谢！

I don't know exactly what went wrong. It has something to do with the environment. It took me a while to configure my JBuilder correctly working with external Tomcat and CVS stuff.
If I were you, I would create a JSP using JBuilder with the same name (LoginIn.jsp) and copy the entire content and paste there to give it a try. If this works (I am sure it will), you have to fight with your JBuilder settings.
I test the same thing as above - create a LoginIn.jsp, copy your content and a dummy lion.LionBean file with only intcCount() method and loginFlag property. JBuilder had no complaint of making it.
Good luck.
