updating RRC articfact using curl cmd

Hi,

I have this curl cmd to update an artifact in RRC:

curl -s -D - -k  -b ~/.jazzcookies -H \'If-Match: \"_C-NbgahsEeKkfY4h6KgkBA\"\' -H \"Content-Type: application/rdf+xml\" -H \"Accept: application/rdf+xml\" -H \"OSLC-Core-Version: 2.0\" -X PUT --data-binary \"\@$ReqType.xml\" \"$updateReqQueryURL\""

$updateReqQueryURL is 'https://clm-host/rm/resources/_KJ60caOvEeKOxKDk7re7Vg"

When i run it, I get the following HTTP response:

Result: HTTP/1.1 100 Continue
Content-Length: 0
Date: Fri, 19 Apr 2013 16:38:44 GMT
Server: WebSphere Application Server/7.0

HTTP/1.1 200 OK
Date: Fri, 19 Apr 2013 16:38:44 GMT
Server: WebSphere Application Server/7.0
Content-Type: application/rdf+xml
OSLC-Core-Version: 2.0
Content-Language: en-US
Transfer-Encoding: chunked

But I don't see the artifact getting updated. In the updated xml file, I'm just updating the Title along with all the other original contents:

From:

<dc:title rdf:parseType="Literal">Touch screen</dc:title>


To:

<dc:title rdf:parseType="Literal">Touch screen test</dc:title>

I don't see any error in the server log too.

Appreciate for any suggestions.

Thanks,
Binoy
