Re: [HAPI-devel] HL7 Message Creation Questions

[James A. <ja...@ja...>]

Hi Harvey,

The datatypes change a little but from version to version of HL7. If you're
using version 2.2 MSH-3 is ST, whereas in version 2.3 it is HD (which is
what the code above is expecting).

If you're using HL7 2.2 you can call
getSendingApplication().setValue("foo");
directly.

Cheers,
James
