我在使用eclips的时候遇到了一些问题，请各位指点：
我以前机器上使用的是eclips2.1.3，这两天从eclips的网站上下载了3.0和3.0.1两个版本，但是运行的时候都出错，无法打开（提示出错，让我去看configuration文件夹下的log文件），下面是出错的log文件（两个版本的错误是一样的），都是xml解析的错误，但是我也不知道应该怎么解决这个问题，请大家告诉我解决办法，十分感谢！！！

看这个：java.version=1.3.1_01
你的JDK版本太低，换个高点的吧。
1.4就没问题了
提示：要确认你的环境变量里面设定的是你安装的JDK安装目录。
因为某些程序会偷偷的修改那些设置，比如说oracle8，9Top

楼上的兄弟回答的完全正确。是jdk版本的问题。。。
刚刚前段时间，我还碰到过一样的问题呢。
后来修改了path就好了。

Eclipse是用java写的.3.0以上必须要jdk1.4以上才能启动.Top

原来是这样，我现在用的是weblogic带的jdk，据说是1.4.3的，看来是骗人的，我重装一个jdk试试看，谢谢几位帮忙，还有就是现在jdk那个版本比较稳定？Top
