Sempre recebo o retorno

Server returned HTTP response code: 500 for URL: https://ws.rodocred.com.br/rodocred.asmx?WSDL at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1436) at sun.net.www.protocol.https.HttpsURLConnectionImpl.getInputStream(HttpsURLConnectionImpl.java:234) at helpernfe.rodocred.Rodocred.execute(Rodocred.java:83) at helpernfe.rodocred.Rodocred.main(Rodocred.java:36)

Alguem poderia me dar alguma ajuda?
