Accessing a sys refcursor as a plsql out parameter

Question

The 11g jdbc guide gives and example of how to access a pl/sql function RETURNING a cursor. We have a stored proc that returns about 5 out parameters one of which is a SYS_REFCURSOR. This is different from RETURNING a ref cursor. Can someone please help me with how to pass a resultset object to the stored proc. I presume the same java declaration is required:
ResultSet cursor;
pass this as a parameter to the stored proc. I have listed the 11g JDBC sample code below:
import oracle.jdbc.*;
CallableStatement cstmt;
ResultSet cursor;
// Use a PL/SQL block to open the cursor
********** HIMANSHU reaplce this with the name of my stored proc dennis1.pkg_snapitall ****************
cstmt = conn.prepareCall
("begin open ? for select ename from emp; end;");
cstmt.registerOutParameter(1, OracleTypes.CURSOR);
cstmt.execute();
cursor = ((OracleCallableStatement)cstmt).getCursor(1);
// Use the cursor like a standard ResultSet
while (cursor.next ())
{System.out.println (cursor.getString(1));}
In the preceding example:
•     A CallableStatement object is created by using the prepareCall method of the connection class.
•     The callable statement implements a PL/SQL procedure that returns a REF CURSOR.
•     As always, the output parameter of the callable statement must be registered to define its type. Use the type code OracleTypes.CURSOR for a REF CURSOR.
•     The callable statement is run, returning the REF CURSOR.
•     The CallableStatement object is cast to OracleCallableStatement to use the getCursor method, which is an Oracle extension to the standard JDBC API, and returns the REF CURSOR into a ResultSet object.

Answer 1

public void readSysRef() throws SQLException {
try {
OracleCallableStatement stmt = (OracleCallableStatement)
// both are ok.
//NOTE: when using call, add ";" after get_empployees() will fail
//connect.prepareCall("{ call ? := get_employees( ? ) }");
connect.prepareCall("begin ? := get_employees( ? ); end;");
stmt.registerOutParameter(1, OracleTypes.CURSOR);
stmt.setInt( 2, 10000);
stmt.execute();
OracleResultSet rs = (OracleResultSet) stmt.getCursor(1);
while (rs.next()) {
System.out.format("Employee %1$s has salary %2$d.%n",
rs.getString(1), rs.getInt(2));
} catch (SQLException e) {
throw e;
}
