jsp 服务器500报错，有劳高手帮忙分析

Question

有劳帮忙看看，之前按照网上的操作方式进行了调整美好

网上的解决方案（但是还是后面的报错）

解决办法：打开%TOMCAT_HOME%conf\server.xml文件，如下：

<Host name="localhost" appBase="webapps"
       unpackWARs="true" autoDeploy="true"
       xmlValidation="false" xmlNamespaceAware="false">
    <Context path="/MyLab2/MyLab" docBase="D:\\Program Files\\Apache Software Foundation\\Tomcat 5.5\\webapps\\MyLab2\\MyLab" reloadable="true">
    </Context>
      </Host>

只要多加这个context就可以了，其中path为访问路径，docBase为项目文件根目录所在。这样应用的文件路径通过docBase来指定，这样就不会再产生找不到class的问题了。

修改为此

<%@ page import="com.ruixin.be.manager.impl.NCManager,org.jdom.*,org.jdom.input.*,org.xml.sax.InputSource" %>

报错

An error occurred at line: 15 in the generated java file
Only a type can be imported. com.ruixin.be.manager.impl.NCManager resolves to a package

An error occurred at line: 17 in the generated java file
Only a type can be imported. org.jdom.input.SAXBuilder resolves to a package

An error occurred at line: 20 in the generated java file

问题描述

<%@ page import="com.ruixin.be.manager.impl.NCManager,org.jdom.Document,java.util.List,org.jdom.input.SAXBuilder,org.xml.sax.InputSource, org.jdom.Element, org.jdom.Namespace,org.jdom.JDOMException,java.text.DecimalFormat" %>

jar文件在lib里，import这些文件出错：Only a type can be imported. XXXXXX resolves to a package

同样的代码在本地测试没有问题，放到服务器上就会出现上述的错误

Answer 1

最后是重新写了一个新的jsp，不再原来的这个jsp里面进行调试了，结果好用了，这个是否也提醒我们不要怕麻烦，重新来过可能比在当前找错更豁然开朗

Answer 2

import把jdom都删掉，改成org.jdom.* 这种形式试一下

Only a type can be imported. XXXXXX resolves to a package

这个的意思是XXXXXX这是个package，不是class，所以你要写XXXXXX.*试一下。
