Hello. I use jssc on my java web app (.war) project on Tomcat7.14. If I deploy 
the only one war - everything is ok. But I can't use jssc in two different war 
projects at the same time, because the second project fells the exception:
java.lang.UnsatisfiedLinkError: Native Library 
C:\.jssc\windows\jSSC-0.9_x86_64.dll already loaded in another classloader

This is due to separate class loaders being used for each web app.  To avoid 
this, you will need to ensure that the jssc classes are loaded by a parent 
class loader.  This can be done by placing the jssc jar in %CATALINA_HOME%/lib/
