见鬼了

我这个eclipse 是从别人那里拷贝来的.他那里就可以使用.(拷贝也没出错).
不是说eclipse 拷贝一个就能直接使用吗?为什么我这个出现上述问题?

narry

检查path和java－home的设置

risingsun

将path的第一个改成jdk的路径就ok了

sakulagi

你用的jre和那个人的jre可能不一样。你是什么版本的jre?

sunnylau

没找到JDK...

sakulagi

jdk找到了，否则会是另外的错误信息

见鬼了

我的机器有两个操作系统,一个win pro,另一个win server.同一个Eclipse,在pro版本下就没问题,在server 版本下就是上述毛病.
是不是跟操作系统有关,在win server下不行呀?(不过我有朋友他们在server下也行).
另外不论是3.X的Eclipse都出这个毛病.
原来的2.X就没事(原来别人装的,已经删除了).

见鬼了

我跟另外那个人做同一个项目,所以希望环境都一致.我们的JRE是相同的,从一个地方下载的.

见鬼了

按照risingsun  兄台说的,不过不成.
