[HAPI-devel] Using Hl7InputStreamMessageIterator

[Ian V. <Ian...@he...>]

As the use of HAPI extends deeper into our work practices, building test cases has encouraged us to use example message files. Saving them with the package, and bringing them in as resource streams is the manner we have adopted.
 
Today I stumbled across the Hl7InputStreamMessageIterator, which looks to be made for just this scenario, so I have been having a go at using it.
 
The code below shows my attempt:
 
//        Hl7InputStreamMessageIterator messageIterator = Hl7InputStreamMessageIterator.getForClasspathResource("/au/gov/qld/health/sit/cdr2/CdnPacsCbhInEscaped.dat");
        Hl7InputStreamMessageIterator messageIterator = new Hl7InputStreamMessageIterator(getClass().getResourceAsStream("/au/gov/qld/health/sit/cdr2/CdnPacsCbhInEscaped.dat"));
        messageIterator.setIgnoreComments(true);
//        messageIterator.setMessageType(ca.uhn.hl7v2.model.v24.message.ORU_R01.class);
As is I get a good result, and can step through the messages in my resource file and assert things for my test case.
 
However, the commented out lines, the first being how I thought I might be able to bring in the resource, the second fixing the message to a particular version which I expect won't build.  They return:
 
Compiling 1 source file to D:\JavaDevelopment\RisToCdr2\build\test\classes
D:\JavaDevelopment\RisToCdr2\test\au\gov\qld\health\sit\cdr2\CdnPacsCbhTxCdr2Test.java:52: error: cannot find symbol
        Hl7InputStreamMessageIterator messageIterator = Hl7InputStreamMessageIterator.getForClasspathResource("/au/gov/qld/health/sit/cdr2/CdnPacsCbhInEscaped.dat");
  symbol:   method getForClasspathResource(String)
  location: class Hl7InputStreamMessageIterator
HAPI library in use is v2.1
 
Any thoughts on where I have gone wrong?
 
Thanks
Ian
