Why would you want to store the whole document in a single parm? Seems
like an odd way to go about it.
- Well from all the documentation in WDSC and on the web you create a java program that actually calls an RPGLE Service program passing the parms which in this case is an actual XML Document. I even called iSeries support because i did not like the idea however thats what they tell me i have to do... Thats why i am trying to find out from others if anyone else has had this type of project to do.
If you really want to store it in memory, use a pointer to teraspace.
Receive the data from your stdin, and save it to memory chunk by chunk.
You can allocate up to 1 terabyte of data to a single teraspace pointer.
You just have to work with the data in chunks. Have a 65535 field based
on a pointer that works with 64k of the data at a time, then advance to
the next 64k of data, etc, until you've processed it all. (or whatever
size field you think would be appropriate)
However, I don't think I'd even try to load the whole thing into memory.
Either I'd feed it to the XML parser as it comes off the wire, or I'd save
it to a stream file in the IFS, and use that file as input to the parser.
There's really no need to try to stuff it all into a single character
variable.
- I totally agree just feel like I am stuck with what I have read and heard from Support.

Incidentally, have you seen my articles on using Expat (an open source XML
parser) from RPG?
- Yes I have and I have to say great work on that. I have installed and started playing with it however my real first step is getting this service up and running. I was also thinking trying to find a way since the web service is just a java program to have the java program place the XML on the IFS then just do a call to the RPGLE Service program stating its on the IFS however not that familiar with Java yet soo... just trying to find a solution... Thanks for you input and the great articles about Expat!!!!
