JSR-108 has been replaced


Martin Desruisseaux



JSR-275 is ready


We make use of a Units library for keeping track of the difference between meters and feet etc... We have been making use of an offical JSR-108 jar.

There were two replacements available once we upgraded to Java 5

  • JScience
  • JSR-275

The JSR-275 jar is now officially available:


The work has been completed.

Voting results:


This section is used to make sure your proposal is complete (did you remember documentation?) and has enough paid or volunteer time lined up to be a success.


no progress






lack mandate/funds/time


volunteer needed

  1. Fix the dependency in GeoAPI, and deploy a new jar
  2. Fix any and all compile errors (mostly import statements; but may make use of the Quantity package with Java 5 generics and catch a few mistakes)
  3. Update the user guide; there is very little documentation on Units use so this will not take long.

API Changes

Change the import; use Quantity package.

There is one additional change related to Converter. I will document it in this page when I will make this change in GeoTools. Since I don't think that many use Converter directly, it will probably impact few peoples.



Note the class name change from Converter to UnitConverter.

Documentation Changes

We will need to change the following:

  • Developers Guide references to JSR-108
  • User Guide references to JSR-108
  • No labels
