I've realized one problem (and am still looking for a good solution). Let
me explain how a sample JSP flows:
<Database Query is Done>
Things printed to PrintWriter
<Another Database Query is Done>
This printed
...etc
Now my <Database Query Done> tags can do a sendRedirect if there is an
error executing the SQL.
So, say my first database query is done, then things are printed, then the
second query bombs. It will try to do a sendRedirect, which ofcourse won't
work because the servlet output stream has been written to. (Aside note,
this DID work with build 131 - but according to the spec, it probably
shouldn't have).
As I see it, my options are to either:
1) Do all queries at the top of the JSP before any HTML is printed. The way
the JSPs are structured, this would not really be acceptable.
2) Somehow have my "out" PrintWriter really be a buffer. Then, when
everthing is done, print to the real output stream. I'm not sure how
possible this would be....
Any other ideas?
Thanks.
