[SalesForce] How to resolve system call out exception

I am new to webservice task . I am getting an exception like

System.CalloutException: Web service callout failed: WebService
returned a SOAP Fault: Internal Error faultcode=env:Client faultactor=

I know what is callout but dont have any idea about the remaining things specified here .
Please tell me how to resolve and what exactly the error is about ?

I have seen this done in two different ways

on callout failure, use apex to recreate your outbound xml, send it using httpRequest and parse the response xml to get your error message
add an 'error' string field to the response class. You then do your webservice call to an intermediate layer which hides these exceptions and always returns to salesforce a 'valid' response.

both of which are just workarounds to salesforce limitations

[SalesForce] Problem to run Amazon web service S3 integration code supported by Salesforce

You have to modify the endpoints based on the region you set up on your bucket. For example, if your bucket is in Northern California, you will have to:

Change (or add a new one) the Remote Site URL to: https://s3-us-west-1.amazonaws.com
Change lines 178 and 1407 of your S3.cls file from:

'https://s3.amazonaws.com/soap';

'https://s3-us-west-1.amazonaws.com/soap';

Be sure you have access to the bucket, your key and secret are up to date, you created an AWS Credentials record with them, and you changed the AWSCredentialName variable value to whatever your credential's record is named, as explained here.

[SalesForce] Web Service Callout exception: Invalid Session Id

pluto,

just like you take the sessionId from loginResult and set it to sessionHeader, you need to take the serverURL from loginResult and assign it to the api object endpoint URL.. and the sessionHeader you initialized is not being assigned to the actual callout object.

vNapp.SessionHeader = ses;
vNapp.URL = lr.serverURL;
