CEA Installation Considerations

This component can be used to "wrap" existing applications or algorithms so that they are presented as IVOA standard asynchronous web services. The applications are formally exposed to the rest of the VO as CEAApplications, which have initial parameter lists defined by their registry entries.

This component provides support for wrapping

  • Exiting commandline applications
  • Existing web form based HTTP applications
  • Custom written Java applications

Suitable applications are subject to two main constraints

  • they have no graphical interface.
  • they need no user interaction once launched.

You should install this component if you wish to allow virtual-observatory users to run selected applications on your computer. You choose the applications that may be run. You must obtain and install these applications; they are not supplied with the CEA CEC. The applications will run on the computer where you install the service, and you must provide sufficient resources (CPU, memory, disc space) for the applications to run efficiently.
