Weblogic10在AIX無法建域：UnsupportedClassVersionError

今天在AIX上使用Weblogic的config.sh腳本創建域時出現了如下錯誤：

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

通過錯誤信息比較容易判斷，其實這就是安裝時使用的JAVA版本不正確所至，Weblogic1034對JDK的要求是1.6以上，而這台服務器的WLS安裝時使用的JDK版本是1.5的，在commEnv.sh腳本裡面可以看得到：

# 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

因此現在使用時雖然用戶環境指定的JAVA版本是1.6的，但是安裝生成的文件都是使用1.5編譯的，所以會出現這個問題！

冒失只需要把commEnv.sh腳本裡面的JAVA_HOME設置為1.6的JDK就可以了，但是為了保險還是重裝了。
