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.

[Hardhats-members] Java-client access to VistA RPC (Remote Procedure Calls)
I've been asked to look into the possibility of using a Java client to access VistA via the RPC Broker. Is this perhaps something simple that has already been done (I hope, I hope, I hope) or will it require inventing (as opposed to reinventing) the wheel? --- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.

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.

Re: [Hardhats-members] Java-client access to VistA RPC (Remote Procedure Calls)
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. A wild guess without seriously looking under the hood - I think something like 3-5 man years will be needed to port it for freedom from Windows. But then if someone has attempted it, or made a better estimate, and would be open to working together, we could look at partnering. The other model is an Open Source one. Anyone interested?

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)
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.
