eclipse报错 eclipse启动报错解决方法

报错之一：
version 1.4.2_03 of the jvm not suitable for this product.version1.5 or geeater is required
大概意思好像说我的jvm虚拟机的环境 1.4版本过低，让我用1.5版本以上的，很疑惑。。。我安装的jdk是1.7的。
不过jvm是;

c:\documents and settings\administrator>java -version
java version "1.7.0_07"
java(tm) se runtime environment (build 1.7.0_07-b11)
java hotspot(tm) client vm (build 23.3-b01, mixed mode, sharing)

c:\documents and settings\administrator>

解决方法：

在我的电脑－高级－环境变量path中，将系统变量path里面的内容调整一下，oracle的内容全部移到最后边。如：
%java_home%\bin;%java_home%\lib;%java_home%\jre\lib;%systemroot%\system32;%systemroot%;%systemroot%\system32\wbem;c:\program files\common files\thunder network\kankan\codecs;d:\program files\ati technologies\ati.ace\core-static;d:\oracle\product\10.1.0\db_2\bin;d:\oracle\product\10.1.0\db_2\jre\1.4.2\bin\client;d:\oracle\product\10.1.0\db_2\jre\1.4.2\bin;

错误原因：

因为我本来安装了oracle，oracle的jre变量值优先于java，所以导致java的jre失效，报错xxx未找到。必须把oracle的放在最后，放在中间也不行。
