java.io.IOException

[lusha tak]

Hello friends..
I am including my test code which establishes a ssl connection to a server and posts an HTTP Post request .which then sends the response back.
This code works fine with jdk1.3.1_01.
But when i try to run the same code sample on j2sdk1.4.2_02, i get Socket Exception. Unexcpected end of file error just after the System.out.println(hello....10)statement. On searching the net i found there is a bug in URLConnection's getContent Method of j2sdk1.4.2_02....which has been fixed in j2sdk1.4.2_03....so i downladed the same.....and tried to run the same....but now it gives java.io.IOException....
what could be the reason??
pl. throw some light..

Lusha, could you please post the IOException stack trace that is being thrown? That usually helps in defining the problem.
