when jvm is short of memory then it uses garbage collector for
removing all objects in heap which are not referenced anymore.
so my tech lead says to close all connections other wise i may end up
ut of memory exception.
which is basically caused when no. of class files are more in the web app
or if the class files are not garbage collected even though the some web app is
why this happens? why the class files of some app are not garbage collected even though
app is undeployed.
thanks in advance

Here you're talking about OutOfMemory error of
container (not of your app).
Servlet Container has it's own classes etc.
You may get this error if the initial PermGen size is small.
It is sorta covered in the
JavaRanch Style Guide
subject: Permgen space:outofmemory exception analysis
GC (Boone's Exam 2)
Reg Garbage Collection
java.lang.OutOfMemoryError: PermGen space
