I will second the remarks about this particular behavior. It is a bug and isn't normal
behavior. I believe the behavior was present in version 5 and 6.
the solution is to well, not do that, since it's not logical. what I ended up doing
was to place the sendRedirect logic at the top of a JSP page and redirecting before
anything happens. that was the only way i could ensure correct behavior, especially
when redirects and forwards were used together to direct a request.

You probably have code which is sending data to the browser and then the
response is getting committed. Then you try a
RequestDispatcher.forward(). This is illegal with respect to the spec.
It could be because weblogic had a larger buffer than tomcat before
flushing. See the jsp(and/or servlet) spec for the declaration to
enlarge the buffer for your request.
A simple way to reproduce:
/* Write a 50kb string to ensure response is committed */
char[] c = new char[1024*50];
java.util.Arrays.fill(c,'z')
out.println(new String(c));
%>
---------------
Another common way is to get this error is by performing a sendRedirect
in a jsp and then printing more data out, for example:
Wacky text here.
---------------
A simple way to resolve:
return;
%>
Wacky text here.
