A Simple XML Question ..but I am stuck !
Hi all,
Please excuse me for posing such a simple question in this list.But I am
stuck and I dont seem to have any solution..
All I am trying to do is to embed a XML String in a SOAP response..
that is in my registered SOAP service I want to return a XML String.
Which I am constructing ..using the JDOM APIs
But I want to remove the version,encoding info from that since it is already
embedded inside the SOAP XML...
Ex:
<?xml version="1.0" encoding="UTF-8"?>
<SOAP Envelope>
.....
<response>
<myname>Naggi</myname>
<urname>Joe</urname>
</response>
.....
</SOAP Envelope>
BUT THE JDOM PARSER ADDS A
<?xml version="1.0" encoding="UTF-8"?>
<SOAP Envelope>
.....
<!--aDDED BY THE jdom STUFF which I want to remove
!!!!!!!!!!!!!!!!!!!!!!!!!!!!-->
<?xml version="1.0" encoding="UTF-8"?>
<response>
<myname>Naggi</myname>
<urname>Joe</urname>
</response>
.....
</SOAP Envelope>
How could I remove it ???
I have "graduated" from SAX so my knowledge about JDOM and DOM is limited !!
PLEASE help me if u can !!
Cheers,
Naggi

yeah I agree,
but I could atleast explore it..
Although I would be pretty clumsy..

True,
But using Literal XML Encoding micght serve as a "cheap" solution for me...
Since My response consists of pure XML and HTML enclosed in a CDATA
section...

I guess this is sortof like being stuck between a rock and a hard place.
There is no one economical way of sending XML payloads within SOAP. We use
Base64 encoding to hide the XML prolog and this works ok since payload sizes
are not too big. I will sit down now and compare payload sizes of
LiteralXml-encoded and base64 encoded messages for the same payload.
Of course, using LiteralXML encoding precludes any other type of payload
format (such as plain text, HTML etc), but that might not be a consideration
for everyone.

I am curious, is there a way to serialize "big XML payloads" that is not a
"resource
hog"? Without looking at the code, I would have guessed that literal XML
would be a
pretty good way to send a large piece of XML.

I am curious, is there a way to serialize "big XML payloads" that is not a "resource
hog"? Without looking at the code, I would have guessed that literal XML would be a
pretty good way to send a large piece of XML.

When you output an XMLDocument from JDOM, it mandatorily puts the XML prolog
(<?xml...> in the output string. So, I don't think there is a way around it
other than doing the cleaning manually (which is kludgey).
Your problem is the classical "XML payloads thru' SOAP" issue. SOAP (and
Apache-SOAP) till now has maintained independance (thereby, lack of support)
from payload formatss and hence XML payloads are the developer's onus to
handle. You could Base64 encode the payload to hide the XML prolog and SOAP
will not complain. (Base64, however, adds to the size of the packet...up
30%)
The other approach you could use is to serialize the RootElement using the
"LiteralXML" encoding
that Apache-SOAP provides, but this too is a resource hog for big XML
payloads.
