What our customers are saying…

We decided to try the free trial and contacted Krengeltech to support us through implementing a proof of concept. They got us started with some skeleton code for composing (Outbound) and de-composing (Inbound) XML. Within a matter of days I had adapted the code to work with our own systems and had a working compose/de-compose proof of concept which produced XML Files – validated with the browser and bank. The support and communication I received from Krengeltech for this was second to none. Furthermore I would also say that the design and general concepts of RPG-XML Suite potentially saved months of development time. Having worked on developing soft-coded utilities over the years, I could safely say that, had I the time, this would have been the exact approach I would have taken. The design concept is very impressive.

RPG-XML Suite is unique. It is purely aimed at RPGLE developers, with no need for any other programming skills – including a very small learning curve.

I would have no hesitation in recommending this product. I currently have this project in user acceptance testing being hammered by a team of 20 testers. It is the biggest and most important project for the company. RPG-XML Suite has been great – no problems or issues. In fact, the proof of concept code has since been easily adaptable for even the most complex conditional XML. It works, and it stays that way. I found the support extremely helpful and responsive to my needs. Not only that, I’m a purist at heart and some of the developments I have seen over the years for client-server applications quite frankly make me weep. RPG-XML Suite is top quality – and I’m not easy to please.

RPG-XML Suite is an excellent tool. I first came across the tool when working on an application for a customer that runs several hundred Web Service transactions each day. I was using an open source tool originally and ran into some major problems with reliability at peak times. I went looking for a commercial package and installed the trial. Installation was complete in minutes, and the tool plugged in very easily to my application. Immediately, my problems were solved. RPG-XML Suite had all of the features I needed and always performed reliably – even at peak times. I immediately recommended it to my customer and they have not had a failed transaction since. Since then, I have recommended RPG-XML Suite to many satisfied customers and will continue to do so in the future.

Utilizing RPG-XML Suite with great guidance from the Krengeltech support team we successfully consume UPS web services to create electronic return labels. This is the best package support I’ve received from my 15 years of AS400/iSeries experience.

Alla Ginzburg, Fidelitone

With the help of RPG-XML Suite I was able to cut my personal project time in half. RPG-XML Suite is a proven toolset that allows for easy creation of XML web services from RPG. I’d recommend it to anyone on the iSeries / System i platform because it runs natively in RPG with Apache giving it excellent performance!

Bruce ‘Hoss’ Collins, AAA Cooper Transportation

Just wanted to let you know how things are now going.

My proof of concept program now works like a charm, and we are using that to build the different procedures we need to be able to transmit the different transactions to that web site and receive a response.

Words cannot convey what your help meant to me.

How you were able to determine what needed to be done based upon the information I sent you just astounds me. If you ever put onto paper how you were able to do such a thing, please let me know as I would definitely be at the beginning of the line to obtain a copy of that.
