Is there any alternative to solve this problem.I am getting the error
java.nio.BufferOverflowException .This happens in my mail server when
the file six\ze of xml where i have stored data about spam/nonspam
grows upto 22mb.I have stored this xml in database as blob.at server
startup uploading in in my class.Keeps througout in JVM after every 50
th request saving information back to database(about spam/nonspam).Now
if xml size grows i am storing this in string to parse etc.it gives
this bug error.Sholud i cahnge my datatype or use something as XML
Parser to split my xml in pieces(mechanism i am not aware of at all) so
that string just takes some size of xml (but here can i use string
builder etc.). Now is there any proper solution to this kind of problem
whenever i removes some daya from xml spam mail goes to inbox and vice
versa.
Please suggest me some solution if possible.

complete error is:
