        依然无法解决JSP报错信息。 
      
          额，这个是一个项目中的一个模块，其他模块配置大同小异，都是JBOSS-3.2.5下，可以直接改JSP页面（运行时自动加载JSP页面）唯独这个模块不会自动更新 
          JSP，谢谢~ 

解决方案 »

  1.   

    额，没什么人气啊……
    现在的问题是修改JSP页面后不自动编译成.CLASS文件
    不知道个各位大侠有什么好的解决的办法伐？
      

  2.   

    哎，不是JAR包问题。 
    原来开发的人员用JIKES编译JSP的。 
    非WINDOWS环境，重新编译后没留文档，哎~ 
    WEB.XML里面加了一段解决问题。不过依旧感谢LS的帮助。 
    <init-param> 
                <param-name>compiler </param-name> 
                <param-value>modern </param-value> 
    </init-param>
    哎，结了
      

  3.   

    请问LZ
    <init-param> 
                <param-name>compiler </param-name> 
                <param-value>modern </param-value> 
    </init-param> 
     放在哪里?
