oracle开发人员创建了它们的API - PL/SQL函数，它将RECORD作为参数。问题是，它由参考记录表的其他记录组成。将复杂的java类传递给pl/sql函数
create or replace TYPE QR_OS_REC AS OBJECT (
ICO VARCHAR2(8),
OS05 DATE,
OS09 QR_TAB,
CONSTRUCTOR FUNCTION QR_OS_REC RETURN SELF AS RESULT,
MEMBER FUNCTION validuj RETURN PLS_INTEGER
);
我需要从EJB调用具有这样的IN参数的函数。我阅读了很多教程，但他们都解决了具有标量属性的bean。我应该怎样处理QR_TAB类型的OS09？
谢谢
EDIT1：
我试图嵌套STRUCT与StructDescriptor，但第二STRUCT初始化期间失败（抱歉不同类型的比上述样品）
StructDescriptor keywordStructDesc = StructDescriptor.createDescriptor("SCHEMA.KEYWORD_REC", conn);
Object[] keywordAttribs = new Object[1];
keywordAttribs[0] = record.getKeyword();
StructDescriptor osobaStructDesc = StructDescriptor.createDescriptor("SCHEMA.PERSON_REC", conn);
Object[] osobaAttribs = new Object[5];
osobaAttribs[0] = record.getName();
osobaAttribs[1] = record.getSurname();
osobaAttribs[2] = record.getAge();
osobaAttribs[3] = record.isVip();
osobaAttribs[4] = new STRUCT(keywordStructDesc, conn, keywordAttribs);
STRUCT struct = new STRUCT(osobaStructDesc, conn, osobaAttribs);
java.sql.SQLException: Inconsistent java and sql object types

编辑2：
我应该传递对象的内容而不是对象本身。
>> keywordAttribs[0] = record.getKeyword();
<< keywordAttribs[0] = record.getKeyword().getValue();
现在有效。
