Export - Export Applet

in Integration and Hardware • 2 years ago

Hi all,

when I export using Version 1.5 (Windows) the applet is not displayed in the browser (applet area is emtpy). When export the same sketch using Version 1.2.1 everything works as it should.

Is this a bug in Version 1.5 or is there something special I have to do when exporting from 1.5?

Thanks,

Andrea

I just tried with one of my sketches (using no libraries) and it works.
Windows 7, Processing 1.5, Java 1.6.0_25, Firefox 3.6, loading the HTML from hard disk.

Thanks for this test.

In my case this behavoiur is not browser dependent. Both IE 8 and the latest Chrome play the 1.2.1 export but not the 1.5 export.

My sketch uses the treemap library - could that be related ? (Although 1.5 places a treemap.jar in the applet folder on export).

I don't know the Java version processing uses - I've installed the versions that come with Java.

Anybody else experiences problems with exported applets from 1.5?

I've had this since 0194, I moved from XP to Win 7, a newer version of Java, and updated Processing at the same time so I've never quite sure where the problems lie. Either way, on my current system running Processing 1.5, Windows 7 64 I get the processing logo and then a grey box instead of an applet. Same in Opera/Chrome Canary/IE9.

Hope this helps

Java version:
println(System.getProperty("java.version"));

I suggest to try with a simple sketch, perhaps one of the examples, not using a library.
Also, activate the Java console, it might display useful information on the applet (exception or similar).

Thanks for your tips.

Java version of Processing 1.2.1 is 1.6.0_20, the Java version of Processing 1.5 is 1.6.0_24, the "System" Java, that is used in the Browser (and shown by the Java Console) is 1.6.0_25.

The JavaConsole helped to figure out what was wrong:

With the export from the Processing version 1.5 I had to copy all files from the data folder into the applet folder. Otherwise the applet did not find the font and the text files.

The export from Processing 1.2 finds the files in the data folder without problems.

Do your applets (exported from 1.5) find files in the data folder?

I can confirm that. I have a sketch with a VLW font and a library. When exported with 1.2.1, it works fine. When exported with 1.5, the loadFont() fails. Looks like a class loader/resource issue, as the data folder is at the same place in the generated jars. It is worth opening a bug.
