xalan, xerces, jaxp

[Patrick.F.O'Dowd@xxxxxxx]

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
