[FDS-17] FusionDebug fails to launch, with the error “Transport dt_socket failed to initialize”.


This can be caused by one of two things. You can check this by starting ColdFusion from the DOS command line.

  • The port configured in the jvm.config (default: 8000) is already in use. Please try a different port. If this does not help, it could also be that multiple servers are trying to start at once; please see this the linked technotes.
  • dt_socket.dll cannot be found. FusionDebug needs to connect to a debug transport called dt_socket. Could you please confirm for me that dt_transport.dll is in the folder C:/CFusionMX7/runtime/jre/bin. If it is then the C:/CFusionMX7/runtime/jre/bin folder is not being picked up by your windows path. You could solve this in one of two ways:
    • Add C:/CFusionMX7/runtime/jre/bin to your windows PATH variable
    • Copy dt_socket.dll to a folder in your windows PATH (e.g. C:\Windows)

Starting CF from the DOS Command Line (make sure the CF Service is stopped first):

  • Open a DOS window
  • CD to C:/CFusionMX7/bin
  • Type: cfstart
  • ColdFusion should start and you should get an error message if it doesn’t
