Status: RESOLVED WONTFIX

(Core Graveyard :: Java to XPCOM Bridge, defect)

Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.9.0.7) Gecko/2009021910 Firefox/3.0.7 (.NET CLR 3.5.30729)
Build Identifier: 1.9.0.5

When attempting to call Mozilla.initialize() in a Java application on Windows an UnsatisfiedLinkError is thrown.

Reproducible: Always




Here is the stack from MozSwing, but even with simple direct JavaXPCOM code, I get the same error.

I was facing the same problem. It looks like this is related to the way Windows Vista+ loads up the dlls dynamically and some of the dlls needed conflicting with ones in System folders. 

See discussion here - http://geckofx.org/viewtopic.php?id=74

I was able to work around it by copying all xulrunner into project base folder and it worked. Still struggling with some other problems, but the unsatisfied link error seems to be gone.
