TOS DI 6.3.2 HL7 Output Example not working

Anonymous — Sat, 16 Nov 2024 02:19:00 GMT

Hello,

I try to reconstruct this Example from the v6.3 Reference Guide.

1.) At step "5." In the references Guide this Windows appears:

In my TOS DI 3.2.2 I get this window ( the left side is missing 😞

I am able to connect the MSH tFixedFlowInput component with the tHL7Output component

by clicking the save button "Save as generic Schema" and then loading it into the "MSH" component:

When I double click on the hHL7Output_1 component I see that both components are connected:

But If I run the Job I get the following error:

Starting job thl7out at 11:36 27/05/2020.

[statistics] connecting to socket on port 3528
[statistics] connected
Exception in component tHL7Output_1 (thl7out)

Job thl7out ended at 11:36 27/05/2020. [exit code=1]

If I put a tLogRow in between, you can see that the HL7 fields are populated as in the reference Example:

[statistics] connecting to socket on port 3519
[statistics] connected
||^~\&||||||||||||||||ACK||MSGID66|P||2.3||||||||||||

So for me it looks like that the data from the "MSH" component is not successfully read by the "tHl7Output_1" component.

When I look at the java code it also looks like the msg_tHL7Output_1 Variable gets never filled with data:

It gets created and then assigned to an empty ACK Message Object and then the content gets read.

But

962 ca.uhn.hl7v2.model.Message msg_tHL7Output_1 = null;

...


1091 if (msg_tHL7Output_1 == null) {
		msg_tHL7Output_1 = new ca.uhn.hl7v2.model.v23.message.ACK();
		terser_tHL7Output_1 = new ca.uhn.hl7v2.util.Terser(
				msg_tHL7Output_1);
		util_tHL7Output_1.findSegments(msg_tHL7Output_1,
				map2Seg_tHL7Output_1);
					}
					
					
...
					
1153 String resultMsg_tHL7Output_1 = msg_tHL7Output_1.encode();

Can someone help me, I tired to follow the Reference Guide example as much as possible.
