If your project is open source and built with maven it can be published on Maven Central. But it seems to me that it will evolve a lot of work on your part. That would be the long term goal.
In the meantime we can do the following to make a great step forward:
1) Install Nexus on your web site. It is simply a WAR file. You can add it to Tomcat or it can run standalone also. The installation instructions are here: (Crazy URL)https://support.sonatype.com/entries/20 ... k=41690657
2) When you make a release, you manually update the jar to your Nexus using the web page and you specify the right groupid (com.weblookandfeel), artifactid (web-look-and-feel) and the version of course (1.23).
So instead of downloading your jar and uploading it to my private nexus. I can just directly link to your nexus in my projects. We just need the URL of your nexus. When you make an update, I can simply change the version number in my dependencies and the jar will be downloaded automatically. (In fact, we would not link directly to your nexus in our projects, instead our nexus would point on yours so that even if Internet is down for some reason we can still build our projects using the cache of our nexus.)
Once you have your own nexus installed, we can provide you with more help for uploading the jar if you need.
