Byte array question

[dan.winsor]

Hi all,

I'm trying to write through SOAPpy in python to a Java implemented API.
The API for the method I want to use is as follows:

boolean added = SoapService.addAttachmentsToIssue(token,
issue.getKey(),
new String[]{fileName},
new byte[][]{getBytesFromFile(tmpFile)});

I've got everything covered except for the byte array. The byte array
should be holding the contents of the attachment(s) I want to send
thorugh the API. However, no matter how I try it, Java on the other
end doesn't like what I'm passing it there.

How can I mimic a byte array in python? Suggestions on things to try?

What have you tried and how did it fail?

Strings?

OK, I'll put that attempt up front. Here's a couple of tries:

<test code snippet>
fileobj = open('testfile.txt', mode='r')
chararray = fileobj.read()
fileobj.close()

soap.addAttachmentsToIssue(auth,'TST-4','testfile.txt',chararray)

<fails with>
SOAPpy.Types.faultType: <Fault soapenv:Server.userException:
org.xml.sax.SAXException: Found character data inside an array element
while deserializing: <SOAPpy.Types.structType detail at -1216265236>:
{'hostname': '<removed>', 'faultData': <SOAPpy.Types.structType
faultData at -1216226708>: {'exception': None, 'message': 'Found
character data inside an array element while deserializing'}}>

<'nother snippet>
fileobj = open('testfile.txt', mode='r')
chararray = array.array('c')
chararray.fromfile(fileobj, stat('testfile.txt').st_size)
fileobj.close()

soap.addAttachmentsToIssue(auth,'TST-4','testfile.txt',chararray)

<fails with>
SOAPpy.Types.faultType: <Fault soapenv:Server.userException:
org.xml.sax.SAXException: Found character data inside an array element
while deserializing: <SOAPpy.Types.structType detail at -1216482740>:
{'hostname': '<removed>', 'faultData': <SOAPpy.Types.structType
faultData at -1216075252>: {'exception': None, 'message': 'Found

<'nother snippet>
fileobj = open('testfile.txt', mode='r')
chararray = array.array('c')
chararray.fromfile(fileobj, stat('testfile.txt').st_size)
#chararray = fileobj.read()
fileobj.close()

soap.addAttachmentsToIssue(auth,'TST-4','testfile.txt',[chararray])

This one "works" in that it runs, but the server on the other end gets
garbage unrelated to the test file.

I've tried a few other other ideas including other modes for the array
(b/B), but those are the highlights.

Are you sure it is garbage? Have you tried changing byte order?

Ah, that I hadn't. Any pointers to doing that?

You found array.array.byteswap() in the manual and rejected it because ...?

Since I don't do Java, I could be misinterpreting the [][]... Given
that it looks like an array of array, maybe you need a Python list of
strings?

....you suggested it?

In the Java snippet from your initial post the `chararray` argument was an
*array* of `Byte` arrays. A string is just an one dimensional "byte
array". Maybe it helps if you put `chararray` into a list!?

Yup, thanks, that was one that I did try with no improvement:
fileobj = open('testfile.txt', mode='r')
chararray = fileobj.read()
fileobj.close()

soap.addAttachmentsToIssue(auth,'TST-4','scriptattach.txt',[chararray])

fails with:
SOAPpy.Types.faultType: <Fault Server.userException: No such operation
'addAttachmentsToIssue': <SOAPpy.Types.structType detail at
-1216379924>: {'hostname': '<removed>'}>

which is an uglier and less informative trace unfortunately. Thanks,
though.

Unfortunately, this yielded similar results as not byte swapping it.
Thanks for the pointer, though.

Nevermind. Did it in Java. Thanks anyway to all who gave suggestions.
