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 SettingsAdministrator>java -version
java version "1.7.0_07"

Java HotSpot(TM) Client VM (build 23.3-b01, mixed mode, sharing)

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%jrelib;%SystemRoot%system32;%SystemRoot%;%SystemRoot%System32Wbem;C:Program FilesCommon FilesThunder NetworkKanKanCodecs;d:Program FilesATI TechnologiesATI.ACECore-Static;d:oracleproduct10.1.0Db_2bin;d:oracleproduct10.1.0Db_2jre1.4.2binclient;d:oracleproduct10.1.0Db_2jre1.4.2bin;
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。
