Hi Somik,
I have mentioned about the out of memory error problem earlier. last time 
for every iteration of for loop I was adding the whole page to my string 
buffer. so it was giving me the out of memory error. I removed that now. it 
was working fine till yesterday. now I find that error again. this time 
nothing to do with string buffer...and it looks like a real problem. I can 
send you the main class and the yahoo.txt I have. try running it.
Thanks,
Raghav
