That is what i am trying to do, writing on the older image, and then send
out the new version to the browser. I know the caching problem, but just to
make sure everytime , i renewed my servlet, i cleaned up all the temperary
internet files, restarted tomcat, still having the same problem. Seems that
g.drawImage(imageobject,0,0,null) and g.drawString("anystring",10,10)
(where g is a Graphics object) methods don't work at the same time.
