I have a servlet that sends the HTML for a frameset to the
client. In the frameset, the source of a couple of the frames
is a call to the same servlet. I'm having problems getting the
synchronization right in a multi-threaded environment. (All
works fine in STM) In a multithreaded environment, the frameset gets
displayed fine along with the last frame, but the other two result in
"no content" errors. Reloading the frames loads them OK.
I'm thinking that I have to synchronize the member functions
responsible for sending the HTML to the client, but can't
seem to find *what* to synchronize them on. A static servlet
member value? This?
Any help would be appreciated. HELP STAMP OUT STM!

---------------------------------
sample servlet code:
public void doGet(HttpServletRequest req, HttpServletResponse res) {
String action = _req.getParameter("a");
if (action == null) {
// send HTML code for frameset
sendFrameset();
}
else if ( action.equals("f1") ) {
// send HTML code to populate frame 1
sendFrameF1();
}
else if ( action.equals("f2") ) {
// send HTML code to populate frame 2
sendFrameF2();
}
}

frameset code (headers and other stuff omitted):
<FRAMESET BORDER="3" FRAMEBORDER=yes COLS="275,*">
<FRAMESET BORDER=3 FRAMEBORDER=yes ROWS="180,*">
<FRAME
MARGINHEIGHT="0"
MARGINWIDTH="0" NAME="searchframe"
SRC = "http://host/servlet/servletname?a=f1"
>
<FRAME MARGINHEIGHT="0"
MARGINWIDTH="0" NAME="tocframe"
SRC="http://host/servlet/servletname?a=f2">
</FRAMESET>
<FRAME
NAME="contentframe"
>
</FRAMESET>
