Am not running any jar file using java command, there is no separate process id  to find the statistics about. jvm has been initialized from C++

Short answer: JVMSTAT http://www.oracle.com/technetwork/java/faq-141822.html

Long one:
 JVM manages it's own memory, so you set it or you're using defaults and those are differents for every JVM (sun, ibm, jrockit, terracotta ...) and others elements.

Command lines parameters for JVM that affect memory
http://download.oracle.com/javase/1.5.0/docs/tooldocs/solaris/java.html#Xms you'll use Xmx + some MB for the permgen memory.

Using JVMSTAT should be more precise but more complicated to setup
