I've started having difficulties with this as well. I too am reading from a
result set and have setup a counter to
allow a periodic out.flush() but so far to no avail. When reading less than
1000 records the servlet functions perfectly. When reading more than 1000
records Netscape locks up tighter than a drum. (e.g. task mgr. kill)
Tomorrow I'll try adding a wait to allow the stream to flush as the loop is a
little tight.
Recently read something about "multi-response" servlets that addressed this
issue but have not yet researched.
Please post back if/when you find a solution and I'll do the same.
Regards,
