All,

       I tried a invoking a webservice from the sfdc environment. I am getting the below error message -  IO Exception: DER input, Integer tag error 

Details - 

In my Class i included the Certificate and Passed the Basic Authorization also.  Below is the Class i wrote -

    public void callWebService()
        {     
        //Create and set the request data
        WMWebService.eventInput data = new WMWebService.eventInput();
        data.outage_number = outage_number;
          

        String username = 'SFDC';
        String password = 'SFDC';
        
        WMWebService.SDFC_WebService_Service_Port webclient = new WMWebService.SDFC_WebService_Service_Port webclient();
        webclient.inputHttpHeaders_x=new Map<String,String>();
        Blob headerValue = Blob.valueOf(username + ':' + password);
        String authorizationHeader = 'Basic ' +EncodingUtil.base64Encode(headerValue);
        System.debug('Authorization - '+authorizationHeader);
        webclient.clientCertPasswd_x = '';
        webclient.inputHttpHeaders_x.put('Authorization','authorizationHeader');
        webclient.clientCert_x =

        WMWebService.return_x response = webclient.processEvents(data);
}

Don't know what went wrong...Any ideas ??

Thanks,
