applet loader problem: fatal error occured (2): multiple points

[cesarpachon]

hi! I had experiencing this problem with my applets, I already searched google and the forums and it seems to be something related to signing, but I am clueless about how to fix it..
fatal error occured (2): multiple points

[Matzon]

try 2.2.1

other than that, the error seems to not come from the AppletLoader - since it doesn't print "Multiple points" anywhere.

is there a stacktrace or some more info ?

[cesarpachon]

there is not stacktrace, in the java console only appears the text "Multiple points". as I saw in the forums other post with the text "fatal error occurred (X)" I assumed that has something to do with the loader. the other clue is that when I launch locally, from eclipse, it works fine. this only happen in the browser.

got a copy of your html code you are using?

or even better a link to a working example?

[cesarpachon]

of course! the test url is http://www.cesarpachon.com/yummyworld/yummyworld.html .. thanks for your help

[kappa]

hmm, why do you have a <PARAM NAME="cache_archive" VALUE="..."> tag? you should remove that as it spoils the user experience by locking up the applet. You shouldn't need to use anyway.

also notice any thing wrong with this parameter

<!-- Version of Applet, important otherwise applet won't be cached, version change will update applet, must be int or float -->
<param name="al_version" value="0.6.2">

hi! I had upload the html file with your two recomendations, and IT WORKS! thanks a lot!

also do upgrade to lwjgl 2.2.1, its contains lots of fixes for applets.

seems to work fine for me, what OS + browser + jre version are you running?

[indexunknown]

The point is it fails the second time i load it and i have to clear java cache and such before it works again.

XP sp3, firefox latest version, java  1.6.0_15-b03

try and step debug and see whats going on (remote attach to applet, you need to add some options in the control panel for applets - something like: -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,address=3999,suspend=n) then attach with your favorite debugger to port 3999

I found out that if i don't store the lwjgl certificate then it works all the time, but if i have accepted the cert then the second time i load the applet it messes up with validating the certs somewhere in the AppletLoader.java:1142 as in the stack trace can be seen.

[Matzon]

may be because the certificates get stripped or something? - very strange.

[Matzon]

Certificate[] certificate = AppletLoader.class.getProtectionDomain().getCodeSource().getCertificates(); seems to be null if you have pre-approved the certificate - odd... investigating, not sure if its a bug or not
