Getting Bad request error 400 and blank respone.

Hi ,

I was able to submit requests thru SOAP Ui tool without any errors.

Today i tried increasing the socket time in the preferences,after then i am getting bad request error.

Ia m not able to sumbit any request which worked fine earlier and even tried Re-installing soap UI tool ,but no use.

Still i am not able to submit the request (Host: localhost)

I am not sure whether this was due to the change i tried in preferences.

I had verified the error log and http log ,in error log its shoowing javax.wsd.wsdlexception..no definition.
also it is saying unknown host (http://www.soapui.org) which i am not trying to access.

PFA.

But please help me to resolve this issue.
