One of the interesting features in the Globus Toolkit 3 is the possibility of writing a log of interesting events (warnings, errors, debug information, etc.) to the console or to a file. This feature is based on the Apache Jakarta Commons Logging component. In this section we'll add logging to the very first example of the tutorial. You can, if you wish, follow this example by modifying the first example, recompiling it, and redeploying it. However, all the instructions will be given relative to a new directory where the modified first example (with logging) can be found:
