Using runtime.exec to open html file - and pass parameters or set a cookie?

I've got a Java Application where I get UserName, and need to pass it to a webpage. My application calls temp1.html which doesn't use it, but should pass the UserName to another page temp2.html)

Right now I'm using Runtime.exec(iexplorer, c:\temp1.hml)
And I've tried Runtime.exec(iexplorer, c:\temp1.hml?name=abc) but I get an error that cannot find file "c:\temp1.html%3Ftemp1.html"

Not sure if this is the best solution, does anyone know if its possible to set a cookie from my Java app instead, so when temp2.html is called it can retrieve the cookie?

You can't pass parameters to anything but a web server

thanx :)

ASKER

Thanks for your help. I got the answer I needed from objects.

But now I understand why the other way didn't work thanks to armoghan's comment, which was also CEHJ's comment earlier on (I just didn't understand his comment about "local file thing").

Good work guys! Glad you're so knowledgeable =)
