RegisterIndexTableOutParameter of JAVA_OBJECT-elemnt raises Invalid column

Question

i wrote below code
---------------Oracle ---------------------
CREATE OR REPLACE PACKAGE K_WD_COMMON AUTHID CURRENT_USER IS
TYPE TYPEREC IS RECORD(
COL1 VARCHAR2(50),
COL2 NUMBER(3)
--TYPE TYPETAB IS TABLE OF TYPEREC INDEX BY BINARY_INTEGER;
TYPE TYPETAB IS VARRAY(100) OF TYPEREC;
END K_WD_COMMON;
CREATE OR REPLACE PROCEDURE WDTEST_PRC_NESTED_TABLE(TESTTAB OUT RMS.K_WD_COMMON.TYPETAB) AS
BEGIN
TESTTAB(1).COL1 := 'TEST1';
TESTTAB(1).COL2 := 1;
TESTTAB(2).COL1 := 'TEST2';
TESTTAB(2).COL2 := 2;
RETURN;
END;
---------------java code ---------------------
Connection conn = DriverManager.getConnection(url, "a", "a");
ResultSet rs = null;
//System.out.println("ARRAY : " + Types.ARRAY);
String sql = "{CALL RMS.WDTEST_PRC_NESTED_TABLE( ? )}";
OracleCallableStatement cs = (OracleCallableStatement) conn.prepareCall(sql);
//cs.registerOutParameter(1, OracleTypes.PLSQL_INDEX_TABLE);
//cs.registerIndexTableOutParameter(1, 100000, OracleTypes.OTHER, 0);
cs.registerIndexTableOutParameter(1, 100000, OracleTypes.JAVA_OBJECT, 0);
-----------it raises below error
java.sql.SQLException: Invalid column type

Kiyong,
If I remember correctly, "record" types are not supported, but in any case, the type must be declared globally -- it cannot be declared within a (PL/SQL) package. You need to define the type using the "create type ..." (SQL) statement.
Please refer to the java documentation for more details. The documentation is available from:
http://tahiti.oracle.com
Also, the following Web page has links to sample code that demonstrates the use of ARRAYs:

Good Luck,
Avi.
