Colossus / Bugs / #905 July/August 2015 JNLP fails to launch

Clemens Katzer - 2015-08-12

Looks like you are using Java version 1.5. Colossus requires now 1.7:

2015-08-05: I have made a new "official" build with all the recently added features (requires Java 7)

As workaround I have put a build that still works with Java 1.5 to the page on my server.

http://www.play-colossus.net/colossus/play/

As page says, within mid-term future (=next 1-2 years ;-) I will drop 1.5 support.

However, your report make me notice that the jnlp files still say it needs only 1.5:

<resources> <jar href="public-testing/Colossus.jar"/> <jar href="public-testing/libs/jdom.jar"/> <j2se version="1.5+" max-heap-size="256M"/> </resources>

I fixed that now in "main page". With that fixed, it would probably give a more informative error message.

I can't (easily) test whether it works with Java 1.5 now ("my page") and whether it gives a besser message (official page).

Could you try out those two and report back here the result?

Thanks,
Clemens

OK, summary:

Could you try out both the webstart file on official page (should now give a more meaningful error message) and the one on my own page ( http://www.play-colossus.net/colossus/play/ ) (should work with java 1.5) and report back to me what happens?

Thx, Clemens

  I'll be able to test this later today. Thank you for the quick response!

    The 1.5 version launched successfully; I'll be updating my JRE version.
    
    The jnlp from the colossus.sf.net page now has a much better error
    description (but it doesn't seem to support cut & paste for me to show it)
    "The application has requested a version of the JRE (version 1.7+) that is
    not locally installed ...
