Testing a CLEF Extension

  1. Close IBM® SPSS® Modeler if it is open.
  2. If the extension defines a CLEF node or output, we recommend activating the Debug tab of the extension dialog until you are satisfied that the extension is working correctly. See the topic Using the Debug Tab for more information.
  3. Arrange the client-side and server-side files in the required structure. Make sure that the specification file, and any associated resources that the node needs (such as .jar or .dll files), are copied to the correct locations. See the topic File Structure for more information.
  4. Copy the client-side directory to the \ext\lib folder of the IBM SPSS Modeler installation directory.
  5. Copy the server-side directory to the \ext\bin folder of the IBM SPSS Modeler installation directory.
  6. Start IBM SPSS Modeler.
  7. If the extension defines a menu or menu item, ensure that these appear correctly on the main menu system. If the extension defines a new node, ensure that the node appears in the desired position on the correct node palette as defined in the specification file.
  8. Test the extension thoroughly.

    For example, ensure that:

    • node performance does not degrade as the number of fields and records increases
    • null values are handled consistently
    • different locales are supported if required (e.g. European, Far East)
  9. Once you have added an extension, you can still make changes to its specification file. However, any changes you make do not take effect until you restart IBM SPSS Modeler.
