本文介绍了解决JSP编译后未生成JAVA文件的问题，通过修改ibm-web-ext.xmi配置文件来确保WebSphere Application Server正确处理JSP文件。

一般来说，JSP编译后会生成java文件，{profile}/temp/xxx.war/…/yyy.java，但是发现WAS没有生成。参考下面的文档

修改ibm-web-ext.xmi


http://www.omg.org/XMI" xmlns:webappext="webappext.xmi" xmi:id="WebAppExtension_1260808235828" reloadInterval="3" reloadingEnabled="true" additionalClassPath="" fileServingEnabled="true" directoryBrowsingEnabled="false" serveServletsByClassnameEnabled="true">

jsp页面报The superclass “javax.servlet.http.HttpServlet“ was not found on the Java Bu错的解决方法

在初学java Wed 时，在导入外部Wed项目资料时，往往资料中给的静态文件引jsp文件夹，但是每个文件都报红的现象，然后在jsp文件里面出现了The superclass"javax.servlet.http.HttpServlet" was not found on the Java Build Path错误异常。异常分析：可能是在Javaweb工程下没有引入中间件（服务器Tomcat）运行的library 这时首先确认eclipse中server的运行环境是否有配置，设置方法为：Window–&gt

      可能大多数Jsp开发员在写完程序测试通过后，不太会关注Jsp生成的Java文件，其实，通过Java代码，更能体现程序代码的真正含义，对进一步研究程序代码的后台运行情况是非常有帮助的。例如，用Jsp编写代码时，有时候用，有时候用，加不加感叹号，到底有什么不同吗？ （Jsp代码加感叹号与不加感叹号的区别）这类问题在教程里一般不会涉及到，从哪里找到问题的突破口呢——Jsp生成的Java文件！

让WebSphere Portal Server 6.0自动重新装入JSP
Java炖粉条
