Subject Re: java.lang.IllegalStateException: Already called getOutputStream()

Just a place where to look for,

you can not get more than one outputStream (PrintWritter) from a servlet, 
i.e. as a JSP has its own OutputStream you can not create a new one. Use the 
PrintWritter already iun the JSP and do not create a new one.
