It's your classloader right? You can keep track of which loaded classes belong to which packages and then ask your classloader to give you a list based on a package.

the problem is that its to hard to track the each classes and its packages.. i have more then 20 jars..each jar having morethen 25 classes with diff packge structure.. (more then one jar having same package structued classes )

so that i have loade all the classes using Systems class loader..

now my need is to find classes whichare present in perticular package structure..

for Ex. in system class loader it will automatically load java.jang.allclasses;

what i want is if i knew that package name (java.jang)

i should find the class name's like Object,String,Long...etc
