Maybe there is someone who worked with Java Callable Exit.

Is it posible to get all the parameters from request in Java Callable Exit (in java code)?
For example if there is a request:
//127.0.0.1/ibi_apps/WFServlet?IBIF_ex=ata11&IBIAPP_app=vst_portal&FORMAT=HTML&a1=15&b2=12
is it posible to get these parametres (IBIF_ex,IBIAPP_app,FORMAT=HTML,a1,b2) in Java Callable Exit?

Note: the parameters and their count are dinamic, so there can be unpredicted number of parameters, parameter names are also unknown.

I can use HttpServletResponse parameter among other parameters in the exit, isn't it?

My mistake - there should be HttpServletRequest Class
