    You are running in an 'environment'. That does not only consist of your code but also includes other things such as but not limited to configuration files, environment variables etc.
    but when it comes to browser dwr method fails to execute an im getting the following error
    The 'environment' is different.
    Please help me out in that aspect
    Most likely reason is that there is a configuration source (a file or value in a file), which exists in the IDE and doesn't exist when you run it outside the IDE.

    And thus they would be different environments.

    Then you would get a class not found exception.
