[解决办法]
是不是你的ECLIPSE解压不完整导致的
[解决办法]
系统环境变量 PATH里面将 %java_home%bin 目录提前就可以拉!


[解决办法]
将workspace全部删除或移到其他地方后再启动试试
[解决办法]
我也遇到好几次这样的问题,每次都是重启电脑解决的.
------解决方案--------------------

jdk的问题 也许是环境变量没有设置 或缺少eclipse程序文件
[解决办法]
走过，路过，不要错过，好贴！！！
[解决办法]
我遇到过这种情况，是因为jdk版本问题
在环境变量中将jdk的版本设置成jdk1.5以上即可
[解决办法]
是jkd版本问题
可能你的机子上装了多个jdk，然后启动时启动了一个较低版本的jdk，所以会出现这种错误
你可以将eclipse设置一个快捷方式到桌面，然后更改快捷方式属性里的目标：...eclipse -vm c:\jdk...\bin\javaw
-vm 后面跟的是jdk的路径，网上有这种启动方式设置的说明，这里讲得可能不是很详细，楼主可以百度一下
[解决办法]
jdk版本与eclipse不匹配
[解决办法]
jdk版本太低，装个1.4.2以上的版本
[解决办法]
ECLIPSE32要求JDK1.4.2(还是1.4.5)以上,我用1.5
[解决办法]
你在cmd模式下用命令运行一下eclipse -clean(回车)再试一下,你这个应该是插件没有加载成功而导到的,建议安装插件的时候使用link方式进行安装!
