5. If the stored procedure returns multiple result sets, retrieve the result sets.
6. Invoke the CallableStatement.getXXX methods to retrieve values from the OUT
7. Invoke the CallableStatement.close method to close the CallableStatement
Example: The following code illustrates calling a stored procedure that has one
input parameter, four output parameters, and no returned ResultSets. The
numbers to the right of selected statements correspond to the previously-described
steps.
int ifcaret;
int ifcareas;
int xsbytes;
String errbuff;
Connection con;
CallableStatement cstmt;
ResultSet rs;
...
cstmt = con.prepareCall("CALL DSN8.DSN8ED2(?,?,?,?,?)");
cstmt.setString (1, "DISPLAY THREAD(*)");
cstmt.registerOutParameter (2, Types.INTEGER);
cstmt.registerOutParameter (3, Types.INTEGER);
cstmt.registerOutParameter (4, Types.INTEGER);
cstmt.registerOutParameter (5, Types.VARCHAR);
cstmt.executeUpdate();
ifcaret = cstmt.getInt(2);
ifcareas = cstmt.getInt(3);
xsbytes = cstmt.getInt(4);
errbuff = cstmt.getString(5);
cstmt.close();
Retrieving multiple result sets from a stored procedure in a
JDBC application
If you call a stored procedure that returns result sets, you need to include code to
retrieve the result sets.
The steps that you take depend on whether you know how many result sets are
returned, and whether you know the contents of those result sets.

CallableStatement.execute
Invoke this method if the stored procedure returns multiple result sets, or
an unknown number of result sets.
Restriction: IBM Informix Dynamic Server (IDS) data sources do not
support multiple result sets.
