严重: Error compiling file: /d:/Eclipse/workspace/SampleF/work//org/apache/jsp\dispatchingJSP_jsp.java [javac] Compiling 1 source file

最近初学java，觉得这个问题太莫名了。

在Tomcat\webapps\ROOT中放入jsp文件测试，成功显示。
两台机器用的都是j2sdk 1.4.2

❸ 如何用ECLIPSE编译运行JSP+SERVLET呢

呵呵！你最好下载一个MyEclipse5.1，比较好！jsp可以直接编辑，知道运行，当然要配合tomcat

❹ 用eclipse编写jsp文件时第一行出错

用eclipse编写jsp文件时第一行出错，先检查一下有没有语法错误，确实没有的话，再把能正常运行的代码的第一句直接复制粘贴过来，比如项目模板生成的里的index.jsp里的第一句话。
还需注意：
1）不要在中文输入法下，手滑输入了全角空格，这个往往在代码里会导致语法错误。
2）没有写完整一行或一句代码时，因为Eclipse默认打开即时编译，所以也有可能出现错误。
最后要考虑的是Eclipse也有可能是有bug的，因为Eclipse也是开发者开发出来的，不过这个可能性比较小；我用MyEclipse出现过，但是把这个文件关闭掉，然后再次打开就好了；实在不行，就关闭工程再打开，最后试试关闭Eclipse再打开。

❺ eclipse编译jsp超慢

除非你的工程比较大，才需要一些时间，建议你你更换一个其他版本的eclipse，
