I have created a java library and packaged it inside a .jar
file for disribution. I am then using a java's URLClassLoader to
load this jar file on the fly in my ColdFusion code (so that the it
can be installed on other machines without the necessity for access
to the CF/classpath directories).
Everything is working fine and I am able to instantiate my
classes successfully. My problem is that after I instantiate a
class from that jar file, ColdFusion keeps the file open forever.
This prevents me from deleting/renaming the file (effectively
making any updates to the file require stopping the CF service).
I tried setting all the variables which hold references to
the URLClassLoader and the instantiated classes to empty strings or
simulated Null value, and then calling the java.lang.System.gc()
garbage collector multiple times... Nothing seems to make
ColdFusion let go of the .jar file...
Does anyone have an idea how I can make CF let go of the .jar
