Java applet not working - anything obvious I have missed?

[chown33]

Dang it, I was really hoping that would be it.

At this point I'm stumped, so I need to think about it more, and maybe come up with some new things to try. Don't expect that for at least a few hours.

If anyone else has any ideas, feel free to join in.

This is why rather than using the Java "classpath" environment variable, which is the traditional place to declare dependency repositories, Tomcat's start scripts ignore this variable and generate their own classpaths when they create Tomcat's "system" classloader.

Fortunately for users who don't want to use the default class loading methods, Tomcat's classpath options are not hard coded - they're read from Catalina's central properties file, $CATALINA_HOME/conf/catalina.properties.

Found this here : http://www.mulesoft.com/tomcat-classpath

Copy and paste the following line into the Terminal window.

echo $CATALINA_HOME

Copy and paste the complete output from the window and post it here.
If the $CATALINA_HOME/conf/catalina.properties file exists can you attach it to your post?
Seems like Tomcat is screwing up the "classpath" environment variable. If kdum8 has no need of Tomcat it would be best to stop it from starting. Check to see if Tomcat is running by entering the following in your web browser: http://localhost:8080/
Take a look in the /usr/local/tomcat/bin/ directory if there's a file named shutdown.sh. Run it to stop Tomcat.

Hi, thanks!

Right, I ran this code in the terminal

echo $CATALINA_HOME

but nothing was outputted at all, just blank. (I don't have to be in any particular directory to run this right?)

Where would I find the $CATALINA_HOME/conf/catalina.properties file if it did exist?

I went to http://localhost:8080/ but cannot connect.

Finally I had a look inside the /usr/local/ directory but couldn't see a tomcat folder? (This is assuming I checked the correct directory - I first entered

cd /usr/local/

and then typed

ls -a

to show all folders, but no Tomcat? Perhaps I am looking in the wrong place?

Try this:

Create a new user account (non-admin). Log into it. Try the web browsers from that account, after enabling Java applets.

While still in the new user account, open Terminal and paste this into a window:

echo "$CLASSPATH"

Post the output.

Thanks again for another suggestion.

Very interesting. Well there was no output from the code at all, (I can run it from any directory right?), but from the new user account you told me to create all Java applet runs perfectly. The test site, savevid.com, the broker's environment, everything.

So over at the new "test" account all is well in Java land, but here on my admin account things are the same, SNAFU. Does that help you anymore?

Yes, it narrows it down a lot. It's something specific to that account, not something global to all accounts. Now I just have to think of what might be setting it for the admin account.

To start, run these two commands and post the complete output:

ls -laeO ~
printenv | sort

Great! I ran both commands and here are the outputs:

I don't see anything in the output of ls that might be something to directly interfere with Java. It's conceivable that some that's been installed by MacPorts (whose hidden directory ".macports" appears), but I have no way to guess what might interfere, and no way to know what you've installed.

However, I also don't see a CLASSPATH in the environment, so its previous appearance either wasn't in the exported environment, or it was spurious. At this point, I think CLASSPATH may be a red herring.


To see if Java works outside the browser or applet environment, I suggest launching "Java Preferences.app", which resides in your Applications/Utilities folder.

It may take several seconds to launch, but it should launch without error if the JVM is working at all. If it fails to launch correctly (stuck with Application Not Responding), or fails with a dialog, then post that information.

If Java Preferences does launch and show a window, post a screen shot of its main window with the General tab active.

Java Preferences did launch and the requested screen shot is attached.

Excuse my late reply, I was away for a while. Thanks again for continuing to look into this.
