    Web Parts Installation

      Hey Guys,

      I'm trying to install QV Web Parts for Sharepoint but I'm coming across this error. I have completed part 1 through 5 from

      http://community.qlik.com/wikis/qvwebparts9/default.aspx

      Restarted IIS and the server and still got the error. When I convert back to the old web.config file sharepoint works again.

      Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

      Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".

      <!-- Web.Config Configuration File --><configuration> <system.web> <customErrors mode="Off"/> </system.web></configuration>

      Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.

      <!-- Web.Config Configuration File --><configuration> <system.web> <customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/> </system.web></configuration>

          Hi Kristen,

          Did you manage to find a solution to this problem?

          Only I am also attempting to install the "QV Web Parts for Sharepoint" and have come across the same (or similar) problem.

          Have followed the "installation guide", but am receiving the following error:

           

           

          Server Error in '/' Application.


          Server Error in '/' Application.

          Security Exception

          Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

          Exception Details: System.Security.SecurityException: Request for the permission of type 'Microsoft.SharePoint.Security.SharePointPermission, Microsoft.SharePoint.Security, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' failed.

           

          Stack Trace:

          The problem appears to be related to the "SharePoint trust/security policy settings" detailed in step 4)

          Changing the "Trust level" to "Full" (<trust level="Full" originUrl="" />) does prevent the error, but obviously leaving the config in "Full Trust Mode" isn't really an option for a production environment.

              Hey AObi,

              I haven't been able to fix mine yet.

              I did notice on the trust setting to make sure the PublicKeyBlob runs on one line with no new lines (no enters).

                  Thanks for the suggestion Kristen,

                  But unfortunately that's not the problem (already made sure PublicKeyBlob is on one line).

                   

                  The problem appears to be due the CAS (Code Access Security) Security Policy is not getting referenced / picked up correctly.

                      Your error is most likely due to wrong settings in the policy file. I guess everything works fine if you set the trust to Full? If yes, focus on the policy file created. Please find attached an example policy file for reference.

                          Thanks Bjorn,

                          Think I have also identified the cause of the problem...

                      Hey Guys,

                      If you come across this error first you must find out what the true error is. Open the web.config file and change On to Off like below. Don't foreget to change back when your done!

                       

                      <code xml><customErrors mode="On" /></code>

                       

                      And changing it to:

                      <code xml><customErrors mode="Off" /></code>

                       

                      This should result in more useful information in diagnosing the problem.
