Two Java programs have to communicate with each other, To do that I found two possibilities
After looking into the description, I found out, that JavaSpaces is apparently the better solution. Sadly, I can't get it to run. Ever totourial roots me to another installation process, to other files and so on.... :(
How to install JavaSpaces, where to download them etc?
If someone offers me a better solution for it I'll be thankful to (JavaSpaces seems to be from 2005)
this are the websites I found so far: http://www.jroller.com/matsh/entry/intreagued_by_javaspaces_try_blitz (Installation description, not working...) http://www.jini.org/wiki/Main_Page (Download links are broken) http://www.jarvana.com/jarvana/inspect/com/sun/jini/jini-starterkit/2.1/jini-starterkit-2.1.zip?folder=jini2_1/ (Download of jini starter kit)
For one quick start using GigaSpaces, a commercial JavaSpaces product (with a community edition available), see http://www.gigaspaces.com/wiki/display/XAP8/Data+Grid+Quick+Start
Also see http://replay.waybackmachine.org/20070202031207/http://www.theserverside.com/tt/articles/article.tss%3Fl%3DUsingJavaSpaces and http://www.theserverside.com/news/thread.tss?thread_id=42164 and http://www.enigmastation.com/?page_id=425
JavaSpaces is great, IMO (I'm biased, as I work for GigaSpaces... but then again, I work for GigaSpaces because I think the underlying technology is great.) - it's got a very simple API but the transaction model is actually pretty strong, and it's very fast. It's simpler and stronger than JMS, and has a simpler deployment/connection model.
If you're GigaSpaces-averse for some reason ("yikes, someone makes money from this") you can look into Blitz as well.
