posttranslational generated servlet, corresponding to the body , there is the following code :
out.write("<h1>?????</h1>\n");
out.print( new Date()); (java in ) with this method : print (Object), without this method : write (Object)
but there is this method : write (String)
Find javaAPI, you will find .

out.print () method, you can output a java object ;
