Re: libgcj.spec

["Rajesh Kadikar" <rajeshk at nortelnetworks dot com>]

Thanks Tom.That helped.

I have one more question.I am trying to run a very simple program(a minor
modification to the hello world that is there on the GCJ web site) to see
how strings are passed between C++ and Java and am having problems.

I am attaching my files with this mail.

It would be great if I can get some help as I have no clue what is going
wrong.

Thanks in advance
Rajesh

 // The problem is that when I try to print the cstring it only gives me the first character .
