HL7

Does anyone has experience with HL7 (standard for datatransfer beween medical applications) messaging with servoy or one of the supported database systems?

that is just a ASCII file with xxx|xxx|xxx values if i am not mistaken.
You could generate such files just fine. Maybe if you look around you will find java classes that generates these files for you if you input some specific data objects (don’t know one at this time)

What do you exactly want to do?

Want to link my application with a health record system in a hospital, So that essential information, that should be in both, can be transferred.

Is this an example of what we are talking about? http://hl7api.sourceforge.net

that looks like it yes.
You could build a plugin or bean around that code so it intergrates nicely into servoy.

the first question is. What kind of calls would you make from youre solution. (example: plugin.hl7.loadFile())

Something like the example, is what I want to do.

then you need to make the plugin (or hire someone that does it for you)
