HI I am seeing Java for the first time. In the new job, we have IBS on the
IBM i. The company orders are coming to a SQL Server via various
Ecomm sites, using FTP or SFTP and EDI. There is a job in SQL Server that
send these to the IBM i via this IBS Java. Can you direct me please to
understand code such as: what books are considered the musts.
and so on.

The most important book is the one that matches the version of Java you
will be using. It is a bad idea to learn 'Java in 21 Days' when it was
written for Java 3 and there are much better ways to write Java code
since then.

Where can I learn what each of these sections means as they will
want some changes made soon.

import net.ibs.framework.*;
import net.ibs.framework.db.*;
..
public IASWConnection ASW = null;
public String templateAndParmList = " ";
..

private void TTProcessOrdersFromDi( ){
IVariable tmpTble = new IVariable();
int duplicateOrders = 0;
//fill up temp table with orderId's
..

Get the documentation from IBS.

Most Java projects have documentation called javadoc. Search for the
javadoc for the version of the IBS classes that are on your machine.


I'd be surprised if you need to know Java in order to be able to run the
Java code that imports orders into DB2 tables, but I've been surprised
before.
