Jython (not STAX) uses a "u" prefix to indicate a string is a unicode
string for the string entries in the STAXResult when you log the contents
of the entire STAXResult variable.
For example: u'File 1 data'.
The content of the STAXResult variable set after a <process> element is
talked about in section "process: Run a process" in the STAX User's Guide
at http://staf.sourceforge.net/current/STAX/staxug.html#Header_Process.
After a <process> element is executed, the STAXResult variable will be set
as follows:
STAXResult - contains any files specified by returnstdout, returnstderr,
and/or returnfile(s). If no files are returned, STAXResult is set to
special Python object None. If one or more files are returned, the format
of STAXResult is a list as follows:
[ [<File 1 rc>, <File 1 data>], [<File 2 rc>, <File 2 data> ], ... ]
Each entry in the list represents a returned file and consists of a
2-element list as follows:
1. <File n rc> is a number containing the STAF return code indicating
the success or failure of retrieving the file's contents
2. <File n data> is a string containing the file's contents
Files will be returned in the order of standard output, then standard
error, then any files specified with the returnfile(s) element(s).
For example, assume that the standard output of a process was simply "This
is stdout data", and that the standard error of a process was "This is
stderr data", and that you asked for both of these to be returned.
STAXResult would look like the following.
[ [0, u'"This is stdout data"\r\n'], [0, u'"This is stderr data"\r\n'] ]
Here's an example of a STAX job that shows how you can log a process's
returned file content without the "u" prefix (unicode string
representation):
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE stax SYSTEM "stax.dtd">
<stax>
<defaultcall function="main" />
<function name="main">
<sequence>
<!-- A STAXResult variable from a process that started successfully
and returns
one or more files will be a list with the following content:
[ [<File 1 rc>, <File 1 data>], [<File 2 rc>, <File 2 data> ],
... ]
The file data entries in the list are unicode strings and will be
logged
with the "u" prefix when logging the entire STAXResult variable.
For example:
STAXResult=[[0, u'"This is a test"\r\n'], [0, u'']]
-->
<log message="1">'Test 1: Log a process STAXResult variable'</log>
<process>
<location>'local'</location>
<command mode="'shell'">'echo "This is a test"'</command>
<stderr mode="'stdout'"/>
<returnstdout/>
</process>
<log message="1">'Process RC=%s STAFResult=%s STAXResult=%s' % (RC,
STAFResult, STAXResult)</log>
<!-- Show how to log a process's returned files (e.g. stdout, stderr)
string
content individually (so that the file content does not have the
"u" prefix).
For example:
Process STAXResult[0,1]="This is a test"
-->
<log message="1">'Test 2: Log a process STAXResult[0][1]
variable'</log>
<process>
<location>'local'</location>
<command mode="'shell'">'echo "This is a test"'</command>
<stderr mode="'stdout'"/>
<returnstdout/>
</process>
<if expr="RC != 0">
<log message="1">
'Process failed with RC=%s, Result=%s' % (RC, STAFResult)
</log>
</if>
<if expr="STAXResult != None">
<iterate var="fileInfo" in="STAXResult" indexvar="i">
<sequence>
<!-- Log each string containing the returned file contents
individually
to avoid seeing the unicode string representation: u'The
string' -->
<log message="1">'Process STAXResult[%s,1]=%s' % (i,
fileInfo[1])</log>
</sequence>
</iterate>
<else>
<log message="1">'Process STAXResult=%s' % (STAXResult)</log>
</else>
</if>
</sequence>
</function>
</stax>

Subject: Re: [staf-users] Python issue with new STAF
HI Sharon Lucas,
That issue has fixed by doing some changes in python code. I am getting
one more issue with new STAF/STAX. In logging I can see STAX is prefixing
extra character "u" in result and while parsing the parameters from xml
file. Do you have any idea why it is sending this extra character.
Thanks in advance.

The latest release of the STAX service is Version 3.5.9. Note that this
STAX version provides support for Jython 2.5.2 (instead of Jython 2.1
which is what is supported by STAX V3.4.5 and earlier). There were
significant changes in Jython from 2.1 to 2.5.2. This is talked about in
the STAX History file and on the STAX download web page at
http://staf.sourceforge.net/getstax.php. Jython is used to execute the
code within a <script> element in a STAX job.
If you provide the content of your <script> element at line 333 in file
/home/hydragui/ATF/lib/framework.xml, I can try to help you resolve the
issue. The Jython error message states that in line 10 within this
<script> element, it is encountering error: "OverflowError: an integer is
required". And what is the value of the variable(s) used in line 10 of
this <script> element? It appears that an integer is not being used for
something that requires an integer. Integer operations that flow outside
the range of integer values raise an OverflowError. If an integral
numeric risks exceeding the maximum value for a PyInteger (2147483647), it
should be made a long integer (PyLong) by adding the L suffix (e.g. 0L
instead of 0). You can also google for more information on this
Jython/Python error message.
