MG>i would not drop application specific jars into endorsed
MG>since this is specific to one application dropping jaxb jars to endorsed
would impact all implementations that use the JVM
MG>potentially causing mis-behaviour side-effect by other applications
implementing their own JAXB implementation
The web-inf/lib contains jaxb-api.jar, jaxb-impl.jar, jaxb-xjc.jar and
jaxb-libs.jar and some other jars used by the application.
MG>WEB-INF/lib is where a servlet container will look for all java jars
MG>WEB-INF/classes is where servlet container will look for java classes
MG>decidedly safest (and the most specific) implementation would be to use java
-Djava.endorsed.dirs=

At just over 49 miles long Panama Railway is probably the shortest railway in
the world
As there was no roads from 1885-1914 Panama Railway carried materials and men
to vital locations for the new Panama Canal
