Trouble with the random code in HTTP Request.

Hi All,

Recently I started to use JMETER to execute the
peformence testing . But I have got a problem with the
parameters in HTTP Request. I will be appreciate if
anyone can give me some help as I seem to have run out
of options!
Duing I followed the process to login a website, I
need to send the username, password and the random
code to the Authentication Server in HTTP Request. My
trouble is about the random code which is output from
a java class interface that can be called from the
localhost used the JAVA REQUEST, and the code will be
change in everytime with user login. 
So how can I deel with this trouble, and can I send
the result from the JAVA REQUEST as a parameter in the
HTTP REQUEST?

Thanks,
Allen Ren
