You better escape the value than replacing one character. This doesn't solve your issue on the long run.
See java.net.URLEncoder.
String args = "mainFrame=" + URLEncoder(url, "UTF-8");

Thanks for your help. Now that I think about it, it appears that is what is
happening. I will modify the code tomorrow morning to pass the second
ampersand as an ASCII value.
Thanks everyone for your input on this !!

Oh, I bet I know what you're doing. In index.jsp you're probably
using
the value of mainFrame directly as the url to load in the frame. But the
value of the mainFrame arg is "blahblah.jsp?arg1=hello", not just plain
"blahblah.jsp". That's why you can get arg1. arg2 is just another
parameter being passed to index.jsp.
You need to either escape those &'s so the whole thing after mainFrame= is the value of mainFrame, or index.jsp needs to explicitly
append any of _it's_ args (i.e. mainFrame and arg2) to the frame url.
(or rather, any that you think should be passed on)
