[IDV #NCG-485587]: run time java erros



HI Stu,

By default the IDV writes to:
<user home>/.unidata/idv/DefaultIdv
The process must not have write access to its own home directory. You can
tell the IDV to use another directory with the "-userpath" argument.

As to the headless exception - you cannot run the idv in headless more (i.e., 
with the -Djava.awt.headless=true). The JVM needs to have some windowing 
environment to use.
