Sarah,
Yes, you can build HL7 messages. You need to first decide which HL7
version you want to use and then instantiate a "message" object. If
you selected 2.4, for example, you would then create an instance of a
class under the package "ca.uhn.hl7v2.model.v24.message".
Basically, you can only set values for individual fields, the
lowest-level parts of a message. To get there, you have to step
through a message to a group (see the "group" package), then to a
segment. (In fact, you may need to traverse through multiple groups
before reaching a segment.) You can set values of fields within a
segment.
