自定义的两个java包互相不能访问,甚至同一个包中的java文件相互之间也不能调用。 请问是 什么问题,应该怎么解决? 我的环境变量:
classpath :.;D:\Java\jdk1.6.0_18\lib\tools.jar;D:\Java\jdk1.6.0_18\lib\dt.jar JAVA_HOME : D:\Java\jdk1.6.0_18 Path : D:\Java\jdk1.6.0_18\bin;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files\Common Files\Thunder Network\KanKan\Codecs;C:\Program Files\Microsoft SQL Server\80\Tools\BINN
然后我定义的两个包的路径是: C:\Program Files\Apache Software Foundation\Tomcat 5.5\webapps\myapp\WEB-INF\classes
的下面,一个是 comm 文件夹,一个是 Information 文件夹。 但是 当浏览器的地址栏输入 http://localhost:9090/myapp/index.jsp 时,就说找不到
Information 和 comm 中的 类 。 请问这到底怎么解决呢?????
