请问大家关于pl/sql存储过程的问题？
<?xml version="1.0" encoding="UTF-8"?>
<application id="SP" portal="CWC">
<data-access>
<procedure name="crosopen">
<data-source>crdcrd</data-source>
<statement><![CDATA[ call crd_app.crd_extended_search.crd_open_orders(?,?,?,?,?,?)]]></statement>
上面的crd_app.crd_extended_search.crd_status 三个分别代表数据库，表明，存储过程名对吗？
<parameter-list number="6">
<param>
<type>in</type>
<position>1</position>
<data-type>varchar</data-type>
<name>custId</name>
</param>

<position>6</position>
<data-type>cursor</data-type>
</param>
</parameter-list>
</procedure>
</data-access>

这段是项目中存储过程的xml
这里面的in和out分别代表的什么意思啊？？
好像这里很关键，高手细讲啊~~

//这里代表的是一段存储过程
我想问的是，这两段代码，一个是xml，一个是oracle里面的存储过程，这两个结合起来怎么看呢？第一次接触，这个项目还是用的连接池把好几个数据流连接起来的。
在我们java的dao里面还是要执行以下xml中的方法的
java代码中怎么执行上面的存储方法，有一个excute方法好像。
