heap space OutOfMemory loading pictures
I apologize if this is a newbie question. I suspect it's down to properly configuring Java, but I don't seem to be getting it right. I can tag a couple of photos, just fine, and they show up on the map as they should, but if I load about the third, I get a heap error.

The photos are large (4000x3000), but the files are only about 3Mb. I'm running the Latest_rxtx2 web launch on Fedora11 64-bit under OpenJDK. I've tried expanding the avaialble space (javaws -Xms762m http://soft.bt747.org/BT747_J2SE_Latest_rxtx2_2p2.jnlp) as high as -Xms1024m, but it doesn't seem to make any difference. If anybody knows the answer, or just if I'm heading the right/wrong direction with the -Xms switch, I would be greatful.

Hi I checked the option in
Hi
I checked the option in the startup scripts and I have -Xmx192m - you have something like -Xms192m so the option may be wrongly set in your case.
In the jnlp file I have <j2se version="1.5+" max-heap-size="192m"/> .
Changing the jnlp locally is not sufficient unless in the jnlp you set the codebase to the local path - otherwise the jnlp will be fetched from the web.
The heap issue is related to the thumbnail creation and should not have an impact on the tagging itself. A limited number of thumbnails is created in parallel, I think I had set it to 5 or so.
Also check how much memory your app really uses to make sure that the heap option has an effect.
Hopefully this helps to get the option right. I intended to revisit the thumbnail creation code and even try to extract the thumbnail already in the JPEG, but I did not get around to that yet.
