Stored procedure with custom type failed from jdbc

Question

DECLARE X Abp_Online_Dataselection.BULK_SCHEME_TAB; BEGIN Abp_Online_Dataselection.ABP_ONLINE_SCHEMESELECTION('BSWD','IN','NEW',X); FOR R IN X.FIRST .. X.LAST LOOP DBMS_OUTPUT.PUT_LINE(X(R).SCHEME_NAME); DBMS_OUTPUT.PUT_LINE(X(R).ISSUE); DBMS_OUTPUT.PUT_LINE(X(R).CURRENCY); DBMS_OUTPUT.PUT_LINE(X(R).PRICE); DBMS_OUTPUT.PUT_LINE(X(R).GIFT); END LOOP; END;
Here Abp_Online_Dataselection.ABP_ONLINE_SCHEMESELECTION is the stored procedure which I can run
in SQL client.
How can I access the result returned by this.
What I have tried is this
Connection conn = myservice.getPooledTestConnection();                CallableStatement cstmt =  conn.prepareCall("{call Abp_Online_Dataselection.ABP_ONLINE_SCHEMESELECTION(?,?,?,?)}");         java.sql.Array recarray;         cstmt.setString(1, "BSWD");         cstmt.setString(2, "IN");         cstmt.setString(3, "NEW");                cstmt.registerOutParameter(4, java.sql.Types.OBJECT); // What is the right type?         if (cstmt.execute()) { }
This gives invalid column type exception.

Normally it requires driver specific code.
If it was me I would wrap it in another proc and use a cursor (or whatever it takes) to traverse the result so it returns a normal result set to java.
