Upgrade 1.4-1.6 Problem: Could not determine base pathname of the file

[Anthony Zawacki <zw...@us.ibm.com>]

I am upgrading our software from Xalan 1.4 to Xalan 1.6 (Xerces 2.1 to
Xerces 2.3) on AIX 5.2 using the xlC_r compiler.  I have run into a
problem.  We are currently still using the Deprecated DOM portion of
Xerces.  We are scheduled to upgrade to stop using the deprecated DOM in a
couple of months.  However, there is a desire to pick up the bug fixes to
Xerces 2.1, so I was attempting to upgrade the appropriate code to Xalan
1.6.

I've only had three types of changes:
o  Both projects now support namespaces, so I have generously used
XALAN_CPP_NAMESPACE_QUALIFIER and the Xerces equivalent.
o  I'm now using FormatterToDeprecatedXercesDOM to do the transformation
rather than using a parser liaison to map the xerces document.
o  The XMLFormatter constructor now requires the version as well as the
encoding.

I've changed everything that I see as potential problems.  However, when I
run my application, it compiles six stylesheets, but the seventh fails.  I
believe that I am running into the problem described in:

http://nagoya.apache.org/bugzilla/show_bug.cgi?id=18464

My simple test program prints out 'Could not determine base pathname of the
file' as the result of getLastError() on the XalanTransformer.

I've read the solution in the bugzilla report, but I cannot find anything
similar in the deprecated API.

Any suggestions of what I can do to fix this short of upgrading to the new
API?  That will have to wait for a couple of months yet.

I've attached several files that I've cobbled together that will
demonstrate the problem.

For me, the command line to compile the tmp.C is:
xlC_r -I/home/gerald/xerces-c-src_2_3_0/include/xercesc
-I/home/gerald/xerces-c-src_2_3_0/include/ -qalias=noansi
-I/home/gerald/xml-xalan/c/src/ -I/home/gerald/xml-xalan/c/src/xalanc -g
-qrtti=dyna -qlanglvl=newexcp -qinfo=dcl:eff:ini:rea:ret:uni -bh:5 -brtl
-L/home/gerald/xerces-c-src_2_3_0/lib -lxerces-c23.0
-L/home/gerald/xml-xalan/c/lib -lxalan-c16.0 tmp.C

Then run a.out with tmp.xml tmp.xsl and tmp2.xsl all in the same directory.
It prints the error message.
Running 'Xalan tmp.xml tmp.xsl' in the same place is successful.

(See attached file: tmp.C)
(See attached file: tmp.xml)
(See attached file: tmp.xsl)
(See attached file: tmp2.xsl)
