运行出现如下问题::
Exception in thread "main " java.lang.Error: 无法解析的编译问题:
at HelloWorld.main(HelloWorld.java:18)
Elipse下,一个项目下的这个java文件,导入了,ogsa-core.jar .
似乎问题提示的是 package 这一行,我不知道
package 干什么用, 我的HelloWorld.java文件存储在项目文件夹下。
------解决方案--------------------
觉悟吧,你的第18行有什么,删除了它,为什么在我这里看起来是空行,也许你的特殊字符发到帖子里就过滤掉了
