Mercator new version, finally

This took a while, but...

Much better hardware support including Star-Micronics printers (includes starjpos.jar). Hardware error handling is also much better. The application is getting some good real world use, this release benefits from many bug fixes and enhancements derived from that use, thanks to all the contributors. Note: just download the single .tgz all jars and source are included.

Mercator 0.2-7

The new release was posted yesterday. Many bug fixes and much better hardware support. Note: the current mercator-jars.tgz was coorrupted. A new one will be in place soon. If you are in a hurry, the xerces.jar is the problem file, you can get it from xml.apache.org/dist/xerces-j (version 1.4.3) extract xerces.jar and copy it to lib.

Release Status

It's been quite a while since a release has been made, and I promised one last week but didn't make it, sorry. I am very close though, pretty sure it will happen this weekend.

The tie-up has mainly been supporting a pilot site in the Netherlands which is finally (sort of) stable. All the work for that will be part of the next release so it will benefit from some real-world usage and some actual hardware integration. The application now supports a Line Display, Epson printer and attached cash drawer. Plus there were many bugs in the internationalization components. So if you are still waiting, it will be just a little longer.

I managed to get the current release, 0.2-2 into CVS. Get the globalretailtech project, data was a mistake and I am working to get sourceforge admin to remove it, it is a duplicate of globalretailtech (newbie mistake)
