Error when using Client object model in Sand box solutions

Posted By:      Posted Date: October 28, 2010    Points: 0   Category :SharePoint
 

Me created a web part using sandboxed solution

And used share point Client object model (.net managed COM) to access a list which is there in another site collection,

Getting error as follows:

Web Part Error: Unhandled exception was thrown by the sandboxed code wrapper's Execute method in the partial trust app domain: An unexpected error has occurred. 

Is it possible to get data from other site collection in same web application using sharepoint client object model?

Using the Client Object Model to read values from Excel file produces 504 error

  

Hi,

I use the Client Object Model to retrieve and read values from an Excel file. This is triggered in an Event Receiver on the Document Library where the Excel file lives. I use a simple CAML Query to retrieve the file. This has worked just fine on a dev/test server. 
Now, I just recently deployed this solution to a production/live server and now this code doesn't work anymore. I get an error saying 'The remote server returned an error: (504) Gateway Timeout'. This happnes when I try clientContext.ExecuteQuery();

The difference between the two servers is that on the test server (where it works) the solution is sitting as the root site, so to speak. No host headers or nothing.
On the live server, there are several web applications (SharePoint) on the same port, but with different host headers.

I have tried to trace a little bit and I found that on the test server, the url that is used to create the ClientContext object is 'http://<servername>/<webname>'. The url is comes from the following code: web.Url. I tried changing the url to the DNS name the test server has and that resulted in the same error as on the live server.

Does anyone have any idea what I need to do?

Thanks a billion!
