IllegalStateException in WL8.1 but not in WL5.1

Question

          I am migrating my application from WL5.1 to 81.
          I have a piece of Servlet A which forwards to another Servlet B for processing.
          After Servlet B is done, the control is passed back to Servlet A which finally
          ends with a response.sendRedirect to a URL. In WL5.1, this is perfectly alright.
          But in WL8.1, IllegalStateException is thrown as the response is already committed.
          I noticed that in WL5.1 the response remains uncommitted after the forward to
          Servlet B, but not so in WL8.1, thus the exception.
          Is there a change in the specification from WL5.1 to 8.1? Why the different behavior?
          (I know, it is a bad idea to have multiple forwards or sendRedirects within a
          servlet.)

hi,
stefen.
look this sample code.
u will get a clear idea.
table emp
empno name
a sasi
b xxx
c yyy
table sal
empno salary
a 1000
b 2000
Inner join
select eempno ename
s~sal
into table int_table
from emp as e
inner join sal
on
eempno = sempno.
if you made inner join between table a and b by emp no
the selection retrives only if the condition satisfy the output will be
a sasi 1000
b xxx 2000
Outer join
select eempno ename
s~sal into table  int_table
from emp as e
LEFT OUTER JOIN sal
on
eempno = sempno.
if you made outer join (left /right ) the left table kept as it is the
if the condition satisfy the right table entries will fetch else leave it blank
the output will be
a sasi a 1000
b xxx b 2000
c yyy
