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
sixze 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.
