Java Compiling on HPUX 11.00

["Iain Wiseman" <bibble at paradise dot net dot nz>]

I am currently involved in developing a schema generator from an XML
spreadsheet.

I original wrote the code in Java and all works well. We (the royal we)
thought it might be a plan to distribute a binary rather than classes
and we (again the royal we) had the bright idea on using gcj. We have a
variety of platforms, including Linux, Sun and HPUX. 

When I tried to compile on both Sun and Linux using 3.0.4 it failed
because it does not support the org.xml.sax.SAXException. No problem I
thought we will compile the ,jars from the sun web-site. But that failed
too. 

As luck would have it the gcc 3.0.4 compiler had major issues with
shared libraries on HPUX (gotta love hpux) and we were forced to go to
3.2 and this did contain java 1.4 and of course the
org.w3c.dom.Document. Well almost.

I now (after some considerable time) have two problems

On Linux
1) Cannot find javax.xml.parsers.DocumentBuilderFactory;  

On HPUX 
1) gcj will not build 

Fails on some files because of _REENTRENT and on the file <ffi.h>. I
have disable the library but it still complain about zlib  targets.

After all this here is my real questions

1) Will it ever work on HPUX 11?
2) What alternatives are there?

Regards,

Iain
