Thanks your reply!
This is a new way that I've never thought of. But after I did some research of gcj, I think it's not suitable for my scenario. Since it actually convert the codes 2 times for using( java 2 c, c 2 perl) it will take much time to diagnosis when any issues happen.But I'll try this way on vacation. ;) Thanks
