Using Xalan-J in JZOS

Hi.
I´m trying to execute a XSL transformation in JZOS but am rewarded with

Code: Select all

SystemId Unknown; Line #-1; Column #-1; Premature end of file.
in STDERR.
I can read the XML document and dump it to System.out thereby verifying that the file is accessible. The first line, by the way, is:

Code: Select all

<?xml version="1.0" encoding="ebcdic-cp-se"?>
What I am trying to do is to process a xml document generated by a set of Rexx-procs in a sequential FB/80 dataset with a stylesheet residing in USS. The result of the transformation is published as a wiki-page (on another server).
This process works allright when I´m executing on a client (windows) but when I deploy the application on z/Os I get the above error. The application ends with rc=0:

Code: Select all

JVMJZBL1015N MVS commands are DISABLED                               
JVMJZBL1023N Invoking se.swedbank.cmnbaseline.Transformbase.main()...
JVMJZBL1024N se.swedbank.cmnbaseline.Transformbase.main() completed. 
JVMJZBL1021N JZOS batch launcher completed, return code=0  

But unfortunately the wiki page is empty.
What I feed into the transformer is:

Code: Select all

Transformer transformer = tFactory.newTransformer(new StreamSource(
	"/u/s000lbj/CMN2Wiki/baseline2wiki.xsl"));
ZFile tZosFile = new ZFile("//'" + aXMLFile + "'",
	"rb,type=record,noseek");
transformer.transform(new StreamSource(tZosFile.getInputStream()),
					tOut);
Does anybody have any idea on what I´m doing wrong, it would be nice to, if possible, run this process in its entirely on z/Os.
Regards Lars

I'm not sure if this is your problem, but you shouldn't be opening the dataset in record mode. Try it this way:

ZFile tZosFile = new ZFile("//'" + aXMLFile + "'", "rt");

I tried the "rt" (that I didn´t see before in the C-manual, probably missed it) but the result was the same.
I also tried to do a (Java) copy of the file from MVS to USS and then trying to feed the USS-file to Xalan but that didn´t work either unfortunately.
I haven´t given up completely yet but as of now I don´t have the time to pursue the problem. If I find at solution I´ll post it here however.

If you would like to send me a a small sample program and test files to info@dovetail.com, I try to see if I can figure out what is wrong.

Problem solved........
Suddenly it occured to me that this might be an encoding problem and sure enough, it was.
Due to my inability to understand the intricacies of encoding I failed to see the impact of not using UTF-8 in conjunction with the wiki soap API (the resulting document).
I am not sure however which parameter that does the trick so I coded:
JZOS_OUTPUT_ENCODING=UTF-8
and
-Dfile.encoding=UTF-8 -Dos.encoding=UTF8
Suddenly everything worked..... (even the swedish national characters that are generated by the stylesheet).

Thank you for your interest and helpful comments.

I've started to run some unit tests, no problems so far. The load time is slow, but I expected that. Curiously, when I run groovy from the OMVS shell, no output is written until I press enter. If I telnet in, everything is fine.
