[ale] help with java crash

Later versions of Firefox are disabling the Java 1.6 plugin as insecure (at least on Windows).   Typically they prompt me to enable it each time I use Java since it is the only version I have installed on Windows.  (I have to use 1.6 for older tools we have here.)

Also I’ve told it to launch the Java Console any time I use Java so I have some clue as to where it is in the load – some Java applets load very slowly.

Linux can have more than one version of Java installed.    It may be you aren’t using the version you think you are.   On some distributions you can use the “alternatives” setup to decide which one to use by default.

Do you have Java NoScript or similar plugin in your Firefox?  It may be it is silently blocking things you haven’t allowed.

For what it's worth, the "Do you have Java" applet at Java.com didn't work with IcedTea at all for me, but our own Java application came up just fine. Also, the Java console never came up, but I did find stdout and stderr in these files:

~/.icedteaplugin/java.stdout
~/.icedteaplugin/java.stderr

The expected things appeared in those files when I ran our own Java app. And lots of stuff appeared when I tried to run the Java.com applet, but nothing that explained why it didn't appear to run correctly in the browser.

Hi Ron,

You should find something called the "IceTea-web Control Panel" on your menu. Then click "Debugging" on the left and Enable logging and Java Console: Show on startup. At least, that's what I have on OpenSUSE 12.3 with OpenJDK 7.0.21.
When your Java applet begins, a separate window should then appear with log messages.
I haven't had that much luck with the OpenJDK implementation on Linux and have been using the Oracle JVM, but I haven't tried it for a year or so, so perhaps it's pretty much caught up now. As I just did a new install, I haven't gotten switched over from the IcedTea version yet on this box. Is this a private web app or public? Applet or JNLP? Firefox or Chrome?

Scott

Hi James,

I see your point.  However, there is no error that appears on the screen.  The tab holding java.com just locks up, and the whole browser becomes unresponsive to the point of being unusable.  If there's a log file that's relevant, I would need to know where to find it and what to look for.

Sincerely,

Ron
