Yes, this is true if you start Tomcat manually. If you want the Ant 
script (deploy action) to start Tomcat you don't have to worry about 
LD_LIBRARY_PATH. The script will set this variable for you.

There is no specific rules for metadata file names. It's up to you how 
you want to call it.

or eXist GUI client application can be used if  you have installed eXist
