Re: xalan, xerces, jaxp

Patrick,

You can install the latest and greatest versions of Xalan and Xerces.
If you go
to http://xml.apache.org you will find those packages. I not hesitate
to use
Xerces 1.4.4 and Xalan 2.2.D14. I would check back for Xalan 2.2 soon.
There
are two options being considered, one that would include another
developer
release (like .D14) that moves to Xerces 2.0, and another to release
now with
Xerces 1.4.4.

I don't know how IBM's versions of these correspond to the Apache
release
system. In the past IBM has been quite a ways behind. I have heard this
is
because they test more thoroughly. I also suspect that it has to do
with
WebSphere the WebSphere testing process and also WebSphere iSeries
releases follow other platforms. When V5R1 was released, IBM did cut
this
time gap considerably.

Depending on what you are doing, there are also other options. I like
to use
JDOM and Saxon because they are simple and fast.

Hello,
I am writing a batch java routine that reads xml message from an
mqseries
queue, the messages are converted to a delimited format(comma or tab)
and
written to a file on the ifs.
The routine must run on AS400, NT, Unix. It uses xalan to do the
transformation from xml to delimited format.
The AS400 is at V5R1, it has JDK 1.3, it has xalan101.jar and
xerces103.jar
in directory ibm/ProdData/OS400/xml/lib/xalan101.jar. It also has
x4j400.jar and xslparser.jar in directory
/qibm/ProdData/HTTP/Public/jt400/lib.

Some of the licensed programs on the AS400 are:
5769AS1        *INSTALLED     IBM WebSphere Application Server
5722DG1        *COMPATIBLE    IBM HTTP Server
5722JC1        *COMPATIBLE    Toolbox for Java
5722JV1        *COMPATIBLE    Developer Kit for Java
5722JV1        *COMPATIBLE    Java Developer Kit 1.3
5722WDS        *COMPATIBLE    WebSphere Development ToolSet
5722WDS        *COMPATIBLE    Tools - Application Development

Q1) Are the .jar files mentioned above part of websphere?
Q2) Which is the latest set and is there a more recent set I could
install?
Q3) The xalan classes in xalan101.jar seem to be named differently to
the
xalan classes on the PC e.g. XSLTProcessor, XSLTProcessorFactory,
XSLTResultFactory. Is the jaxp package available on the AS400? With
this I
am hoping to make the code platform independent.
Q4) Can anyone relate their experiences on using xalan and xerces on
the
AS400?

Thanks,
Pat O'Dowd
