Getting java.lang.ClassCastException

Question

Hi All,
I am getting below exception when I am trying to establish HTTPS connection using
Exception: java.lang.ClassCastException: HTTPClient.HttpURLConnection
sometime my code works and some time it gives me this exception
below is the exception which i traced in a log file
2008/09/11 01:07:57->1_1210001776_0:1_1210001776_0URL CONNECTION CALLED https://netfundstest.com/fsu/router

2008/09/11 01:07:57->1_1210001776_0:entered into else Block
2008/09/11 01:07:57->1_1210001776_0:1_1210001776_0Error URLC Not a instance of HTTPS Connection: HTTPClient.HttpURLConnection[https://netfundstest.com/fsu/router]
2008/09/11 01:07:57->1_1210001776_0:Exception: java.lang.ClassCastException: HTTPClient.HttpURLConnection
In the success case when my HTTPS connection gets established I am getting following in the log file.
2008/08/24 11:51:28->1_1210001776_0:1_1210001776_0URL CONNECTION CALLED https://netfunds.com/fsu/router
