Problem passing array of objects soap between java (axis) and delphi
Christoph Donges
connect to it. For simple stuff it seems to work fine but when I try to
pass an array of objects I get the error "A name contained an invalid
character" and then the first line of what looks like html.
Can someone help me, or am I just pushing soap too far? Have other
people successfully passed arrays of objects?
The Comps method fails, but the z method (that just returns a string) works.

Sounds like a data problem.. Some character inside your data that when
converted across XML is not a valid character... My guess is it might be
like a quote in dad like ... Roger's ... which would make some wierdness
happen. I'm guessing though.

No.. You arent pushing soap to hard. We are passing objects back and forth
over soap...and even lists of objects from axis to a Delphi Client. The
implementation of Delphi 7 Soap out of the box wasnt to fast, we've sped it
up quite a bit. But, we are passing large arrays *Fairly* quickly.
As far as the rest of the posting... I'm no expert, however, I'll be happy
to look... We;ve just started our soap implementation on a small scale.. but
have big dreams for it.
