Java4k Launcher (v1.1)

[Gef]

I've tested the 2 versions of the launcher on my Win7 64bit with JRE7 and the results are the same :

- Supway4k produce this


- In The Dark 4K works for me

One suggestion, can you reactivate the "Play Game!" button when the window's game is closed ?.

EDIT: No problem with other 2014 games

I'll check out those issues soon and post an update when I have a fix.

If someone wants to volunteer to make a Mac bundle, please stand up.  Or, I guess I coulld invest some time looking into this article (http://www.intransitione.com/blog/take-java-to-app-store/), but I don't have any way to test it.

I could make that for you. I'm having holidays till this friday.

That would be greatly appreciated!

Also you should add judge comments

I'll check with Appel to see if he could add those to the Json output.

I get the same error as Gef when attempting to play Supway4k.

However I am still unable to play In The Dark 4k... a game window is displayed that is completely blank (black) and no mouse click/keyboard events cause any change..

The Supway issue was due to a parsing problem with the applet size. Launching the tool from the jar directly isn't supported, so I added better error reporting. I'm still looking into the exe issue.

The issue around The Dark is actually due to a threading issue (I wouldn't have been able to find it without the posted source - thanks Gef!).  This is the same issue that some applets encountered when running on a Mac - the applet container wasn't ready when the graphics context was requested. Some applets will loop at the start, waiting for the isAvailable() call to return true.

I don't know the right fix for this one. Should the launcher be made to match of one specific JVM behavior (Windows) or another?

well I would say yes, target the behaviour of the most common jvm as that should mean most entries should be playable.

This has been the source of much controversy in the past, specifically in the 2009 competition when an update released near the end of the submission period introduced a bug in the applet lifecycle. Unfortunately I can never find the detailed analysis that I wrote up back then.

I added the fixes to the security classes, image size parsing, and some other little nuggets that were hiding around.  Still no judges comments 

Java4K.exe doesn't work and neither does the JAR. Running the BAT file works.
The error with the JAR is a NullPointerException in File's constructor when you call it at line 80 of your Security class.

The direct-from jar launching should report a better error now.  As for the Java4k.exe - if run the "no bundled jre" version, it expects a 32-bit version of the JRE to be installed.  If you only have the 64-bit version, I'm guessing it won't run.  Which version did you try out?

My Chrome browser just updated to the latest JRE.  Now, I get this error whenever I attempt to launch a 4K applet:



I'm sure I can tune the security settings, but I guess this is how most people will see the site from Chrome now.

Edit:

Through the Control Panel, I was able to turn off the check.  Now, I get this:



Ugh.

I get the same result in Firefox after the recent update. That message after you turned it off is what I already got in FF before the update.

Yup with Java 7u51 and after, ALL applets and webstart applications must be signed and the permissions attribute set. These are easily google-able though so it's pretty easy to sign your application and set the permissions.
