you can do something like
String bundleSymbolicName = ...
Bundle[] bundles = bundleContext.getBundles();
for (Bundle bundle : bundles) {
if (bundleSymbolicName.equals(bundle.getSymbolicName())) {
return bundle;
}
}

Yes bundle filename.
Since second installation also has same file name..I think this would work
for me.

The bundle filename you mean?
There's Bundle.getLocation() but that does not change if the bundle is
updated after being installed, see
http://www.osgi.org/javadoc/r4v42/org/osgi/framework/Bundle.html#getLocation
()
- so you usually cannot rely on that. The Bundle-SymbolicName/Version combo
is the only stable identifier AFAIK.

Thanks, I think this will solve my problem wherever I have symbolic name. I
have some places I have only bundle physical name. Is there any otherways to
check based on physical name?
