关于ORACLE中的存储过程的XML使用

调用一个存储过程（别人写的），这个存储过程介绍如下
我不明白的是参数v_str，是一个XML？
是要JAVA生成一个XML对象来传给存储过程吗
在JAVA里如何来执行这个存储过程    PROCEDURE fpgl_jxhxgl_createPrintsn(     
    /*
    9.生成购销存明细帐单的打印编号
    */
         v_nsrbm       IN VARCHAR2,      /*[1]纳税人编码*/
         v_czydm       IN VARCHAR2,      /*[1]操作员代码*/
         v_gxczt       IN VARCHAR2,      /*[1]购销存状态1：购 2：销 3: 退*/
         
         print_sn      OUT VARCHAR2,     /*[1]打印编号*/
         vc_message    OUT VARCHAR2,     /*[1]处理过程消息*/
         vc_flag       OUT VARCHAR2,      /*[1]处理过程标记*/
