hello

information:
tomcat6 is running my jsp page ,so all the linux commands too are executed by tomcat6.
but i want to run these linux commands from a different user etika on my system through this jsp page which is executed by tomcat.

(on running the linux commannd the ownership of the file gets changes to tomcat6 but i don't want the ownership of the file to be changed on executing it ,so can i run this linux command from a different user etika so that my ownership doesnot changes )

In case you only want the date from the server, you can try the
java.util.Date Class from the Java library as well.
