When i run the CSSExport importexport.properties utility i receive the following error. Any ideas/suggestions will greatly help me

Trace...

Here is how my importexport.properties file would look like

importexport.css=http://...com:58080/interop/framework/getCSSConfigFile
importexport.cmshost=Sharedservices server name 9.3.1
importexport.cmsport=58080
importexport.username=admin
