I am working on a Web Application;
I added libraries to my project via "Java Build Path" Application is running perfectly but when I made changes to my .jsp file and refreshed the the page on Browser;
the added libraries automatically removed.
Now how can fix it??? i am using apache-tomcat-7.0.37.
as every time I update my .jsp file or make any other changes I need to add the libraries again.
Any advice or suggestion would be highly appreciable. Thank you!

What is the contents of the .classpath file in your project. That might
provide some clues or provide help in determining the next questions to ask?

This file shows no evidence of being a Dynamic Web Project. If
something is removing entries, it doesn't appear to be Web Tools doing it.

I don't know if I can help, but the next step would be to look in the
..project file to see if any of the natures or builders give a clue as to
what Eclipse plugins may be "messing" with the project.
