Unsupported Operation. Check application log for more details.

This is my second day learning ColdFusion. I am able to display .cfm pages. However, when I tried to browse/load the .cfc file, I kept getting this error.

Unsupported Operation. Check application log for more details.

These are my simple testing codes.

<cfcomponent hint="A first CFC">

    <cffunction name="getValue" returntype="String" access="public">

        <cfreturn "Hellow World">

    </cffunction>

</cfcomponent>

Where is the "application log" so I can check for more details?

Correct answer WolfShade

You're not actually supposed to "browse" to CFC files, typically.  But if you were to do that, then you might want to give the function an output="yes" attribute.

The logs are easily viewed from within CFAdmin (go to Debugging & Logging on the left navigation, then choose "Log Files" under that, and click on "application.log" in the list of logs.)

Alternatively, you can also use Windows Explorer (or whatever file viewer your OS uses) and navigate to {cfDirectory}cfusion\logs, find the "application.log" file and open it.

HTH,

    Thank you for the reply. This is what the log says: To use Component Browser, enable RDS Service using Administrator. Note: RDS is intended for development use only.

    Where do I enable the RDS Service?

    As WolfShade said you shouldn't really be "browsing" to your cfc files. They are not intended for use in the browser. They are like classes that you main pages instantiate and use the methods inside. Basically the cfm (view) calls the cfc (backend).

    For example you might have something in your cfm page like

    <cfset var = createObject('component', 'myCFC')>
    

    <cfset text = var.getValue()>
    

    <cfoutput>#text#</cfoutput>

    In this case text would output "Hellow World" (Based on your first post)

    If you do want to enable RDS then this can be done by going to the Coldfusion Administrator and selecting Security > RDS from the menu. Browsing to the cfc will then just give you a break down of the functions available and what they return.
