3 years ago Hello mstar46,
It's definitely possible to have different JARs in the same page :) There are several things:
Please move the content of the "live" folder in the current folder as ".." is ignored.
To get the same behaviour in CheerpJ as in native use the option {enablePreciseAppletArchives:true} in cheerpjInit(). The default option is false for backwards compatibility with previous versions of CheerpJ. Without this, CheerpJ will not be able to load the second jar archive.
By doing this, you'll notice that the error message changes from load: class Live not found to java.lang.SecurityException: class "Live"'s signer information does not match signer information of other classes in the same package. You need to take out the signature from the live.jar (this is true in native too). On Linux you can run zip -d live.jar 'META-INF/*.SF' 'META-INF/*.RSA' (other options here: https://stackoverflow.com/questions/7757083/how-do-i-unsign-a-jar). colorsurf.jar is already unsigned, so no need to modify it.
I tested this in local copying the page http://www.polyhedra-world.nc/stuff/colorsurf_.htm (ignore the background color and fonts, I didn't copy css and style files).
cheers, sere

(for sere) Here is a page that should display four applets: a small (S) at the top right, a large (L) in the middle, and two medium (M) at the bottom: http://www.polyhedra-world.nc/stuff/colorsurf_.htm - only S works S and the Ms use live.jar, L uses colosurf.jar (both .jar are compiled into .jar.js)
I then created a test page with a minimum HTML code: http://www.polyhedra-world.nc/stuff/colorsurf-test1.htm - only L works (choose increment 20 and use the arrows) Disturbed by this result, I tried two more test pages: http://www.polyhedra-world.nc/stuff/colorsurf-test2.htm - L does not work http://www.polyhedra-world.nc/stuff/colorsurf-test3.htm - only S works Two other tests verify my suspicions: http://www.polyhedra-world.nc/stuff/colorsurf-testL.htm - L works http://www.polyhedra-world.nc/stuff/colorsurf-testSM.htm - S and the Ms work
It therefore seems that the use of a second .jar disturbs CheerpJ who then refuses to do his job. Is there a solution? or can we only use one .jar per page?
