When I try and open it all I get is the Java logo in the center of the screen, the red progress bar shows full progress, and the extenstions on the star behind the Java logo continues to light up and rotate around the logo symbolizing it's still "thinking".

Any other suggestions?

That was me.

If you enable the Sun Java Console, it will display any errors/exceptions resulting from running the applet and they're usually good hints about what's wrong.

What's the version of the Java Runtime Environment (JRE) on the PC where your browser is located? The version information is displayed on top of the Java Console window.

I have JRE version 1.5.

Here is a copy of my Java Console

Don't know about this Java version 1.5.0. From Sun's Java website, there're only version 5.0 and version 1.4.2. (maybe 1.5.0 is version 5.0?)

Anyway, the applet viewer was compiled using version 1.4.2, and I was able to view the same huge image using JRE 1.4.2, so can you try uninstalling JRE 1.5.0 and install version 1.4.2 instead?

In the meantime, I'll try JRE version 5.0 and see if I get the same error. It'd not be surprising to find out the applet viewer compiled in version 1.4.2 needs to be recompiled for version 5.0.

I'll give it a try.

Thanks for all of your help.

Still nothing.

1. What's the error message from the Java Console window?

2. Is this the same sample image you send me previously? If not, can you send me this particular image that's causing the trouble?

I'm using the same version of JRE, so the only question left is:

Is this the very same sample image you sent me previously?

wdc1160 · Post by **wdc1160** » Mon Apr 11, 2005 8:43 pm

Same sample image as earlier, only this one is from version 1.4.2_08

Ok, I'll send you a debug version of the applet that will output more information to the Java Console.

That is me ^^^

I was able to login to your server and captured the debug log from the new applet (It took quite a few minutes to download the 10 M image over even the broadband connection).

This is confirmed to be a bug in the Java Applet where it's not handling the embedded sequence items well. This image is different from the one you sent me so I'll need you to send me another ZIP file with the following raw image file (for testing the fix):

{ArchiveDir}/777.777.0.0.0.0.0.111284990620050323154756000010000000001

where:

ArchiveDir is the archive directory you've assigned to the AE from which this image was received.
