apex 自动导出application
可以采用以下命令行自动导出或者备份apex应用程序：
java -classpath ojdbc14.jar:$ORACLE_HOME/apex/utilities oracle.apex.APEXExport -db localhost:1521:orcl -user scott -password 123456 -applicationid 100
Note:
1. APEXExport 是存在于$ORACLE_HOME/apex/utilities目录下的APEX自带的文件，用于export应用程序。也可以使用apex解压目录下的utilities目录下的相同文件
2. APEXExport 用到了oracle.jdbc.driver.OracleCallableStatement需要使用jdbc驱动程序ojdbc14.jar，ojdbc5.jar或者ojdbc6.jar均不可用。
APEXExport 源码如下：
