I think they are in the middle of a site update which could be delaying their approval process. Following is a summary of the components I've put together: rpcbrokerj - a repackaging of the VistAWeb rpc broker client as a standalone pure java component. Is this something that would be suitable for access as a java applet in Mozilla Firefox? If so, do you see this giving significant performance or other benefits over an HTTP based client if an HTTP version of the broker server were available? I don't know. I see this as a means for a java program to speak the rpcbroker protocol with a VistA server allowing a wide range of java based configurations, applet client, JSP web frontend, webstart client, etc.. All I've done is rework the pseudo-java code in the VistAWeb FOIA to make it real java, although from what I'm hearing of VistALink, this may just be duplicated effort. mj - m parser written in java. Very primitive, doesn't use a proper grammer and generator such as javacc, but it is simple and can be used for building code analysis graphs. Where is this going? MUMPS editor, syntax checking, limited client-side interpretation of input transforms? I seem to recall that there was an announcement some time back of a java based MUMPS interpreter, I think on comp.lang.mumps, but I didn't follow up to get details and I don't know its status now. I goodled for it now and couldn't find it. I've heard something as well of an M interpreter implemented in Java, but have not seen it available. That could definitely open up some interesting possibilities. My main motiviation for putting the parser together was for grokking the 20,000 source files in OpenVista and as a nice way to learn M :-) If this could be used as a basis for some other efforts that would be great. gnpj - Java port of the GT.M GNP protocol which can be used for accessing GT.M globals from java (over TCP sockets). sshscraper - XML based screen scraping state machine that uses Mindterm SSH. This includes scripts, based on Mark Street's installation instructions, for installing and configuring OpenVistA. The variabilities are supplied through properties files and can be driven by ANT scripts. filemanj - java wrappers for fileman meta-data elements. This could be very interesting. Could you give examples of what you have in mind? I have done some work in translating fileman metadata to Javascript that is accessible via M2Web. I understand that the Javascript literal data format is remarkably similar to that of Python and several other dynamic languages and so might be used as a highly efficient means of porting data and metadata objects. That sounds very interesting. Once again, my efforts originated from a desire to better understand VistA/M from a java perspective and explore means on interoperation. My thoughts are directed toward providing meta-data translation and another integration point. Could data models in Fileman be used as an input for MDA program generators? Programs for viewing, managing, manipulating,translating, etc? Is it possible or even useful to create a Java fileman api that uses reflection on these wrappers? It seems to me there could be some promise here and perhaps similar efforts are already underway, thus I'm putting out this set of tools. -Troy Any thoughts or feedback would be greatly appreciated.

RE: [Hardhats-members] Re: Creating Java client for OpenVista
.NET is an open standard. It's just one of the most popular implementations is Microsoft's .NET Framework for Windows. Mono is an implementation of .NET for all platforms. Novell and Gnome will be all Mono within the coming year moving away from the mixmatch of languages currently in use. C# is by far my favorite language to date. It's similar to the Java runtime. Sun's JVM is proprietary in that you can't take it apart and re-package it - but in a single piece, it's highly dependable. Then IBM, Oracle, etc have their implementation of the Java Spec each with varying licenses, etc. So actually - it's closer than you think. Of course I'm a developer that realizes where my clients are and 98% of healthcare is in Windows. Also healthcare is one of the slowest industries to upgrade so their refresh cycle is 5+ years for complete infrastructure upgrades. I always say use the best solution that's available. Be pro-OSS but not only-OSS, anti-MS may not be the best solution because cross-platform development isn't known for its rapid deployment. The best platform for multiple clients is still the browser whether the server is JSP, .NET, PHP, whatever... So why not a browser implementation? Recent advances in client-side browser computing is moving along well (AJAX and Client Scripting such as Google Suggest and Google Maps). The top three clients across the platforms are still: Browser, Java, and .Net/Mono. /David. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Kevin Toppenberg Sent: Thursday, May 19, 2005 8:57 AM To: hardhats-members@lists.sourceforge.net Subject: Re: [Hardhats-members] Re: Creating Java client for OpenVista I don't know much about .NET except that it is infrastructure that MS offers.

Re: [Hardhats-members] Re: Creating Java client for OpenVista
Look into VistALink, it is a pure java environment for VistA access, HelathEVet was designed around it. The namespace is XOB and the latest released version is 1.0. You can get free java development environments on the web, NetBeans and Eclipse are the two I am currently investigating.

Re: [Hardhats-members] Re: Creating Java client for OpenVista
Troy -- Great work!

Re: [Hardhats-members] Re: Creating Java client for OpenVista
Just my attempts to an understanding of VistA/M from what I am already familiar. I am hoping that building bridges between M and Java will help open up VistA to the world of Java open source development. I'm also thinking that the screen scraper interface can make installation and configuration easier. It is primitive (as screen scraping approaches are), but by filling out a properties file with values for siteName, siteNumber, institutionName, etc you can run the script and have the initial installation and configuration run automagically. There are still a few kinks in it, but I'm about 80% through configuration scripts on the Wiki. -Troy Well, you have certainly been busy! I wish I knew more so I could better understand what you have done, but one thing I do know, is that it must have been a heck of a lot of work! Hopefully, you will now be getting some help!

RE: [Hardhats-members] Re: Creating Java client for OpenVista
I know the VA also had internal projects that work in .NET and Java - has anyone tried to FOIA those? When I first started out with making our development tools (VB6 and .NET) work with VistA, I looked at the Java implementation in FixIt and that works in native Java (as I recall). You may want to contact that project to see if you can re-use. I ended up just writing the wire protocol from the Delphi source into VC. For added functionality, I also layered the BDK in an ActiveX control so that internal developers could pick what they wanted. The OCX works really well for any COM based application on Windows - which is most. /David. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of K.S.
