[AXIS2C] Questions about using REST
Hi Senaka, Samisa and Others,
I am now starting to implement REST style calls and have a couple
questions:
1. It seems that a GET REST call only works if a query string with at
least one value is specified in the URI. For example I want to do
"wsclient.exe -get
http://localhost:9090/axis2/services/aewebservices70/GetItem/111" to get
item "111" but that won't work. I have to do "wsclient.exe -get
http://localhost:9090/axis2/services/aewebservices70/GetItem/111?foo=bar
" and then the request does get dispatched to my code. Is there a way
around this?
2. I don't know how to get at the values in the URL, like the "111"
value above which I have mapped like "<parameter
name="RESTLocation">GetItem/{itemid}</parameter>". Do I look up
"itemid" somewhere in the message context? I haven't done much with the
context so any code samples would be awesome. If I want to get query
string values how do I do that?
Thank you for your help!
-Dave.

Thanks, Senaka. My GET test is now working!

Hi again Dave,
I did fix two bugs in the code, with respect to REST, one of which you
reported, and another that indirectly affects. I also tested your
scenario calling the endpoint,
http://localhost:9090/axis2/services/echo/echoString/Hello/ using
Mozilla Firefox, which returned,
<ns1:echoString>
<text>Hello</text>
</ns1:echoString>
Please do try now, I believe it should work for you.

Senaka

Hi Dave,
Unless it is a bug somewhere in the code, that we could not track, you are
capable of calling
http://localhost:9090/axis2/services/aewebservices70/GetItem/111, and
getting the request dispatched. I will check into this and get it fixed.
Also, I believe if you setup RESTLocation, as in the way you say below,
your itemid will get added to your payload (the axiom_node that you get).
It may reside either at the top (before the query parameter info) or the
bottom (after the query parameter info) of your payload, depending on the
way it got dispatched. However, you can access that information in the
very same way you access a query parameter. So, try to browse through your
node.
Also, as it is very hard to figure out a clear-cut specification on REST
fot Web Services, other than of course the HTTP-Binding in the WSDL2.0 and
WADL from which we got an insight, you are welcome to express your
thoughts for additions and improvements to the REST logic in the Axis2/C
engine.

Senaka
