CallableStatement: Calling PL/SQL Procedure from OAF

We need to use a Callable Statement to call either a function or a procedure from OAF.

Here are the steps to call a PL/SQL procedure:

Create a CallableStatement with the PL/SQL block of code to call the stored procedure
Bind input and output variabled
Execute CallableStatement
Capture OUT parameters
Close the CallableStatement statement

    import java.sql.CallableStatement;
    import java.sql.Types;
    import oracle.apps.fnd.framework.server.OADBTransaction;
 
    public void callProcedure() {
 
        String lkpCode = "XX_VAL_LIST_LKP";
        String lkpMeaning = "XX Lkp Meaning";
 
        CallableStatement callableStatement = 
            getOADBTransaction().createCallableStatement("begin  xx_lkp_details_pkg.list_lkp(:1,:2,:3); end;", 
                                                         OADBTransaction.DEFAULT);
 
        try {
 
            callableStatement.setString(1, lkpCode);
            callableStatement.setString(2, lkpMeaning);
 
            //registering out parameter
            callableStatement.registerOutParameter(3, Types.VARCHAR);
 
            callableStatement.execute();
 
            String tagValue = callableStatement.getString(3);
 
            if (tagValue != null) {
 
                System.out.println("Tag value: " + tagValue);
 
            }
 
        } catch (Exception e) {
 
            System.out.println(" XX in Catch Block of callableStatement: " + 
                               e.getMessage());
        }
    }
