loading java libraries

I have an application that runs multiple processes. I was trying minimize memory usage. It seems that Each process loads its own set of common library like java.util.*, servlet.jar, xml*.jar etc. SO looks to me that these libraries are getting loaded multiple times increasing the memory usage.

I remember in C/C++, you have option of dynamic linking, where the library is shared between multiple processes.

Is my interpretation correct? ANy suggestions, guidelines?

Thanks,

Yes, you are correct. Actually this problem is tackled by Sun in the Tiger release: http://java.sun.com/j2se/1.5.0/docs/guide/vm/class-data-sharing.html
