I want to know the meaning of various terms used in above line.
What does
server -Xmx1500m -XX
MaxNewSize=384m
MaxPermSize=512m
means

what does
-Dorg.apache.jasper.compiler.Parser.STRICT_QUOTE_ESCAPING=false
and
-Dhttp.agent=Sakai-News-Tool" mean

and what purpose will this proxy serve is it for having an internet
connectivity of Sakai.
I am not clear with purpose of setting this proxy in Sakai.
I till now have not been able to get a working instance of sakai up
neither from binary package nor the source install or demo package
either.
If you read other thread of mine in this forum you will see.
I am new to Tomcat environment but I hope this much problem should not come.
