Hi, An 'Orkut app' has been developed using the Orkut Client API to work on my application. But now I am experiencing a serious problem when trying to retrieve user's own *Orkut scraps* and it occurs frequently.
I am getting a "NoHttpResponseException: The target server failed to respond" exception when an httprequest is made to the server**. It was occurring sporadically, usually on any initial httprequest.But now this occurs quite frequently. On analyzing the error details, I could make out that it is the "doReceiveResponse()" method in the "HttpRequestExecuter" class that throws "org.apache.http.NoHttpResponseException".And this error eventually causes an "org.apache.http.client.ClientProtocolException" to occur on calling "HttpClient4.execute()" method. I am attaching the exception details with this post. As this occurs in the HttpClient4 class in the Apache server, I am unable to do anything. Please help me out to get rid of this exception happening in the 'HttpClient4' class, as it is quite annoying for the users to see my application failing to retrieve scraps frequently. Thanks in advance. -- You received this message because you are subscribed to the Google Groups "orkut Developer Forum" group. To post to this group, send email to opensocial-orkut@googlegroups.com.
