Weblogic10在AIX无法建域：UnsupportedClassVersionError

Weblogic10在AIX无法建域：UnsupportedClassVersionError

今天在AIX上使用Weblogic的config.sh脚本创建域时出现了如下错误：

[uathzapp@bea]$ ./config.sh
Exception in thread "main" java.lang.UnsupportedClassVersionError: (weblogic/descriptor/SettableBean) bad major version at offset=6

通过错误信息比较容易判断，其实这就是安装时使用的JAVA版本不正确所至，Weblogic1034对JDK的要求是1.6以上，而这台服务器的WLS安装时使用的JDK版本是1.5的，在commEnv.sh脚本里面可以看得到：

# and JAVA_VENDOR are pre-defined.
if [ -z "${JAVA_HOME}" -o -z "${JAVA_VENDOR}" ]; then
  # Set up JAVA HOME
  JAVA_HOME="/usr/java5_64"
  # Set up JAVA VENDOR, possible values are
  #Oracle, HP, IBM, Sun ...
  JAVA_VENDOR=Unknown
  # PRODUCTION_MODE, default to the development mode
  PRODUCTION_MODE=""
fi

因此现在使用时虽然用户环境指定的JAVA版本是1.6的，但是安装生成的文件都是使用1.5编译的，所以会出现这个问题！

冒失只需要把commEnv.sh脚本里面的JAVA_HOME设置为1.6的JDK就可以了，但是为了保险还是重装了。
