Error loading JPEG

[vangun]

I get this error when I try to load any JPEG in Openlaszlo 3.1. I was able to load .jpg images earlier. I am not using the SOLO deployment.

ERROR: null : Exception stack: java.lang.NoClassDefFoundError at org.openlaszlo.iv.flash.api.image.JPEGBitmap.proce ssImage(JPEGBitmap.java:166) at org.openlaszlo.iv.flash.api.image.JPEGBitmap.write (JPEGBitmap.java:247) at org.openlaszlo.iv.flash.api.FlashObject.generate(F lashObject.java:138)

Has anybody else seen this error before?

I know that there was an issue with progressive scan JPG. Try a non progressive scan JPG to be sure.

I see this bug filed for Linux:
http://www.openlaszlo.org/jira/browse/LPP-183

I am getting the same error on Windows, but I am still not sure about the test case. Progressive JPEGs seem to be a problem but not always. Is there some other cause also for this error?

I had the same error when i tried to load a jpeg image from a wms service, my app is deployed (proxied) on a tomcat5.5 server together with other j2ee apps. it worked when first deployed. however, whenever tomcat is restarted, it stops to work with the fowllowing error:

.....

the only workaround i have found is to shutdown the tomcat server, totally redeploy the app, and restart tomcat. this is incomvinient and i am not sure it there any other solutions to this.

In my case, progressive JPGs were the cause of the error. Changing them to non-progressive JPGs made all the difference. But if you are using Flash 8, then progressive JPGs should not be a problem.

that is right, i just tested it with png, and the problem has gone.

Thanks
