Are there any APIs for RPG when it comes to XML-RPC or SOAP at all? (sorry,
but this is really a home match for java isnt it? ;-))
</Marc>

I can speak to this one.  There are tools available to do XML in RPG, but
you get to do everything manually.  RPG lacks in the XML arena because you
really need a suite of tools to do XML (WSDL, SOAP, automated UDDI
publishing, etc).

Java is much more advanced in this arena, not to mention the fact that
passing a generic object from a generic router is much easier in Java than
in RPG because of obvious limitations (size of variables and user type
declarations).

I have been working with RPG and XML for quite some time now and we are
going to move more to Java for that type of processing just because it is
more suited to Java's environment.

If you are doing very simple XML processing then RPG can be leveraged, but
as one expounds into the more complicated documents you will begin to see
where Java (and all the tools provided by the community) help get you up to
speed pretty fast.

Do you use XML-RPC because its easier to generate the XML when not having an
API for it? Or is it because of the performance advantage, which makes
XML-RPC a really useful option in the land of http based remote protcols.
Are there any APIs for RPG when it comes to XML-RPC or SOAP at all? (sorry,
but this is really a home match for java isnt it? ;-))

And i just want to make sure that i dont defend every piece in the java
world. Lets take EntityBeans in their current manifestation. Its really a
painfull spec.

And we totally agree regarding the DB2 for iSeries. I have never seen a more
robust database on any platform. This is why i love this machine, but i
still think that the java implementation could be faster, but i have not
benchmarked this on various iSeries machines, so its just a feeling.

Peace, Love and IBM ;-)
