RCP开发，如何解决org.eclipse.core.runtime.CoreException

我只用了1周学会了RCP，开始开发，比Swing好用多了

当我要导出到发布平台上，竟然报错！

弄到12点没有搞定，竟然难倒我这个java高手。

找死，必须干掉他。

早上想了一下，生产的plugins好像不是jar文件，只是一个目录，难道打包本身就有问题。

运行报我自己写的类找不到，明明就在同一目录阿！！！！

同一目录，一个点代表相同目录

在plugin.xml中classpath中，加入

Up到最上面就搞定了。

没有能难倒的问题！

AIX，我只用了1晚上就学会了。但往往简单的是比较难想到，细节！！！！！
