Re: [Hardhats-members] Java-client access to VistA RPC (Remote Procedure Calls)
Last fall I announced a simple Java client for GT.M (which will eventually deal directly with VistA data) for OpenEMed. The goal here is to allow VistA (and MUMPS data stores in general) to serve as data storage for Java applications - our immediate need is to persist data for OMG CORBAMED services. Our implementations are all Java. I haven't found the RPC mechanism to be terribly useful because I never found enough information about the RPC protocol itself. I resorted to simple MUMPS calls through a socket interface. Michael, we should talk - especially when it comes to workflow integration. We're also making progress (slow) on integrating workflow definitions directly into the software development process. Richard Schilling Cognition Group Seattle, WA USA J.

We do, however, need to augment its functionality to address small-office/clinic workflow issues and provide some automated, user-friendly linkages to an existing practice management system. We were hoping that we could use a Java client to access some of the existing VistA RPC calls and, perhaps, do a little (as little as possible) MUMPS coding to add a couple of our own RPCs on the server side.

Re: [Hardhats-members] Java-client access to VistA RPC (Remote Procedure Calls)
I am not aware of such an effort, and I don't think you will be able to create a credible back-of-the-cocktail-napkin estimate. If you really want a credible estimate, I would suggest running the source code through a reverse engineering tool to create a metric such as the number of function points, the number of menu options or some other measure such as the number of gleeznop brognicks. Set up an agile project such as Scrum and implement some part of the functionality end to end. After one or two Scrum cycles, estimate what part of the total functionality you have implemented, and extrapolate. This won't be a cheap estimate because it will take you perhaps two months to go through the exercise. But it will give you something you can hang your hat on, and something that will give you a basis to track project progress. -- Bhaskar On Mon, 2006-03-06 at 17:38 -0600, Joseph Puthooran wrote: > Has anyone tried to estimate the work involved in redoing CPRS > for Linux - I mean complete with the RPC or else it does not > make sense.

Re: [Hardhats-members] Java-client access to VistA RPC (Remote Procedure Calls)
Why redo it if Codeweavers is going to make it work on Linux using Crossover Office and Wine? Not to mention, that by the time you recoded it, there would be a new version or a bunch of new functionality you would have to add or change. Wiat for Codeweavers or wait for the CPRS-R Java version.

RE: [Hardhats-members] Java-client access to VistA RPC (Remote Procedure Calls)
It does. And you can see that their class structure has a RPC Broker wrapper with equivalent functionality. Dialog Medical has been running an ActiveX control for RPC Broker functionality for some time now. I've seen a .NET Version using remoting and the FixIt model isn't obfuscated. It's not terribly complicated. If you don't want to make native calls, you can always wrap and route. Place web service like functionality on the M/Cache Server and then make calls into it. At some point, you'll want to make calls into the data layer or business functionality without having to only re-use existing calls. Then you'll benefit from having flexible plumbing. /David.

Yes, we definitely do not want to reinvent -- or even modify -- CPRS. We do, however, need to augment its functionality to address small-office/clinic workflow issues and provide some automated, user-friendly linkages to an existing practice management system.
