I had this problem on Linux with Weblogic. The application worked fine on my Windows 2000 machine. When I compared the weblogic.jar files on both machines I noticed that the one on Linux missed the file javamail.default.providers. I added this to the weblogic.jar file on linux (has to be under the META-INF directory). I also had to update the mail.jar and activation.jar files and make weblogic to use these instead of the ones in weblogic.jar (by editing the classpath in startWebLogic.sh). Now everything works fine!

A better solution: Just add mail.jar to bea\wlserver6.0\lib and change the classpath so that mail.jar is loaded before weblogic.jar. (javamail.default.providers is included in mail.jar). Works for me anyway! ;)
