Hi

I ran the program below and I get the following output/error. The Java code tries to get the exchange rate between the currencies of two countries. Interestingly I see the result of the call in the exception trace. I have run the code by passing the http.proxyHost and http.proxyPort as VM invocation parameters.

Is there something missing in the code I have written?

Thanks
Suresh
