Customize list using Info-path - Data Connection Error

Question

We have an issue while customizing list using Info-path, we are configured a data connection inside the info-path the connects to SQL and it works fine.
then we decided to migrate it to another site under another web application on the same server, but it does not work, it fires an error as below:
A query to retrieve form data cannot be completed because this action would violate cross-domain restrictions.
If this form template is published to a SharePoint document library, cross-domain access for user form templates must be enabled under InfoPath Forms Services in SharePoint Central Administration, and the data connection settings must be stored in a
UDC file in a data connection library in the same site collection.
If this is an administrator-approved form template, the security level of the form must be set to full trust, or the data connection settings must be stored in a UDC file by using the Manage data connection files option under InfoPath Forms Services
in SharePoint Central Administration.
An entry has been added to the Windows event log of the server.
Thanks & Regards Ahmed Amin

Answer 1

Under General Applications in Central Admin, go to the InfoPath Settings and Configure InfoPath to allow cross domain connections.
