关于java运行环境版本

Question

小弟，今天安装eclipse的时候，总是提示我JAVA运行环境版本不对，因为我在java -version命令时总是提示我1.3版本，这样安装eclipse肯定是不行的，可是，我已经安装java 5.0版本了啊！而且也配置环境变量了啊！可就是改不过来！！！还是1.3版本！！气死我了！请问怎么才能让它版本升级呢？要不，安不上eclipse啊！郁闷！！

Answer 2

下载JDK1.5安装完成后再执行：java -version
ver1.5应该可以安装eclipse3.0了吧

Answer 3

eclipse -vm 你的jdk5.0的目录\bin\javaw

Answer 4

你安装了Oracle吧，试试重新设置Path，把java 5.0的bin目录设置在最前面

Answer 5

它可能是默认的oracle的jdk的版本，是1。3的

Answer 6

别泄气!全部卸载了,重新安装一次,不过呢要正常用eclipse,JDK的版本必须是1.4_1以上.我的是j2sdk1.4.2_06版本的感觉好不错.试试!!在java.sun.com可以下载到的哈.版本升级呀好不如去下载呢!

Answer 7

你Path这个环境变量设置过吗？？
把 jdk1.5的 bin目录放到 path这个环境变量的最前面。

Answer 8

最简单的方法请参考 dyhml(VirusCamp) 的贴
