Re: Amazon proxy unable to forward request to amazon search service

Synapse can also send REST requests. You need to switch back to the
REST URL and add the following format="pox"
<address uri="http://localhost:9000/soap/SimpleStockQuoteService"
format="pox"/> into the address tag. Please see sample 152
http://ws.apache.org/synapse/Synapse_Samples.html#Sample152

No.. it will only help identify what may be wrong with your environment,
access to Amazon or your proxy server

Yes! I was able to access Amazon over SOAP from behind a firewall as
well as over a direct ADSL connection from home for your exact example
you gave. So the problem you have seems to be on your side... I am just
trying to help you figure out what may be wrong in your network.. if a
basic tool such as telnet is restricted in your environment, I am just
guessing your firewalls may be blocking quite a few requests too :)

Both REST/SOAP (in your case) uses HTTP.. and I think the issue you have
currently is more on the network or http access. Can you try your
example from another network that has direct access? Maybe from home?

Hi,
I am not able to access telnet service from my machine since it is not
allowed. However our networking guys are able to connect to
webservices.amazon.com from telnet (I will send this output to you soon ).
The following url also throws (HTTP 500 Internal Server Error) from our
networking ppl browser.
http://webservices.amazon.com/onca/soap?Service=AWSECommerceService&AWSAccessKeyId=0GGBQRMT1MHNNDN5BY02&Operation=ItemLookup&IdType=ASIN&ItemId=0706922611
So in summary:
1. If I get telnet permission from Networking deptt, will it going to help
me anyway?
2. Has anybody ever accessed amazon service from synapse using soap?
3. Should I try REST now, if yes then please also send the corresponding
REST request XML.
Thanks

I did the same from my office network (behind a proxy) over Firefox and

But I don't think this is wrong.. as Amazon must be expecting a POST
here.. the best I could try now is to ask you to manually try this from
the command line (without Synapse) first.. See the text file I have
attached for more details. First you should open a command line, and
telnet to the amazon server. Then you copy line by line from the
attached text file, and press enter on your telnet session. You repeat
this for POST..., SOAPAction..., and Content-Length.. lines, and press
enter twice. Then copy the text from <?xml version='... ....Envelope>
and paste to the telnet session and press enter twice. You should get
something like the following. You should now send this output to me :)

Re: Amazon proxy unable to forward request to amazon search service
Posted by ali_khan <fa...@gmail.com>.
hi,
I think the problem is due to the firewall because when I put the following
url(REST request) in web browser:
http://webservices.amazon.com/onca/xml?Service=AWSECommerceService&AWSAccessKeyId=0GGBQRMT1MHNNDN5BY02&Operation=ItemLookup&IdType=ASIN&ItemId=0706922611
I get proper result in the browser as an XML.
But when I put the below URL(SOAP request):
http://webservices.amazon.com/onca/soap?Service=AWSECommerceService&AWSAccessKeyId=0GGBQRMT1MHNNDN5BY02&Operation=ItemLookup&IdType=ASIN&ItemId=0706922611
I get (HTTP 500 Internal Server Error)
I think the soap requests are being blocked by proxy.
Please suggest any solution for this, because rest I am doing the same as
you mentioned.
Thanks

Seems like your local cache/proxy server is having issues with the use
of TCPMon.. Usually a POST is of the form "POST /xxx HTTP/1.0" and the
/xxx is the relative URL of the requested resource. However if you
specify a TCPMon endpoint such as http://localhost:9090/xxx a proxy
server may sometimes try to use it and call on itself..
please try the exact configuration I sent without using TCPMon and let
me know. Also use the utilities I pointed earlier to send the sample
request. Since that configuration works for me perfectly, you should be
able to get to this same point first and then try out variations
Let me know how it goes..

Re: Amazon proxy unable to forward request to amazon search service
Posted by "Asankha C. Perera" <as...@wso2.com>.
Ali / Faisal
First of all, it seems like you are trying out the Amazon REST service
endpoint with a SOAP request!
Instead try the endpoint address :
"http://webservices.amazon.com/onca/*soap*?Service=AWSECommerceService"
(Reference http://weblog.plexobject.com/?p=1555)
I tried this with a simple configuration as follows:
<definitions xmlns="http://ws.apache.org/ns/synapse">
<proxy name="AmazonProxy">
<target>
<inSequence>
* <property name="FORCE_HTTP_1.0" value="true"
scope="axis2-client" /> *
</inSequence>
<endpoint>
<address
uri="http://webservices.amazon.com/onca/soap?Service=AWSECommerceService"/>
</endpoint>
<outSequence>
<log level="full"/>
<send/>
</outSequence>
</target>
</proxy>
<send/>
</definitions>
Note that I have had to force the use of HTTP 1.0 protocol (though its
not as good as HTTP 1.1) as Amazon didn't accept HTTP 1.1..
To send a sample request I did the following, however I assume you
already have the required client and thus can skip this step..
I saved the sample request you gave me to a file, and used the following
tool to send this sample request to Synapse as follows:
asankha@asankha:~/perf$ *java -jar benchmark.jar -p amazon.xml -n 1 -c 1
-k -H "SOAPAction: urn:ItemLookup" -T "text/xml; charset=UTF-8"
http://localhost:8080/soap/AmazonProxy *(Reference :
http://wso2.org/node/1721)
I got the successful response without any issues.. let me know if this
works for you now
asankha
PS: Contents of the request file were as follows:
asankha@asankha:~/perf$ cat amazon.xml
<?xml version='1.0' encoding='UTF-8'?><soapenv:Envelope

Have you got a successful trace that goes direct (that is - NOT going
through Synapse?)
