Welcome to the JavaRanch, Lalitha!
JSR historically means
Java Specification Request and it's what is used in the process of defining and implementing an official Java feature. For example, the spec for JSF 2.0 is JSR-314. JSR's are more or less the Java version of the RFC documents that define the Internet standards.
I have no idea what "JSR" might mean as a framework.
The secret of how to be miserable is to constantly expect things are going to happen the way that they are "supposed" to happen.
You can have faith, which carries the understanding that you may be disappointed. Then there's being a willfully-blind idiot, which virtually guarantees it.
