Hello, I would personally find it great to have a Java Web Start link (JNLP) on yacy.net website as an alternative to OS dependent installers (here is a good example on JOSM project website : http://josm.openstreetmap.de/
I think it could be helpful for some newcomers who don't want to "install" something but want to try a local YaCy peer, and may be afraid by github and ant compile.
At least a link to http://latest.yacy.net:81/update/
last stable release would be a good thing.
But a Java Web Start link is easier (only one click needed) and truly cross-platform.
First step to make it possible is to produce a runnable jar. Not a big deal with an ant task, but some other modifications are likely to be needed : for example, at first startup yacy assume default config files are in a local 'defaults' directory rather than in classpath. I have already started to experiment, but as more work is needed, I am wondering what you think of this idea... Have you already tried? Would you support this and eventually add an third deployment link on yacy.net website?
