Salesforce.com connection to Hoover's API through Http Callouts

Hi,

I am trying to make a callout from APEX to an HTTP endpoint(Hoover's API)  but am receiving the following error:

 
 500, internal server error'.

Here is my Apex class :



global public with sharing class HttpCallout_CLS {

    Public static void sendRequest(){
   
    String API_KEY = 'XXX';
   
    String env;
    env =  '<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:sch="http://applications.dnb.com/webservice/schema/">'+
             '<soapenv:Header>'+
                '<sch:API-KEY>XXX</sch:API-KEY>'+
             '</soapenv:Header>'+
             '<soapenv:Body>'+
               '<sch:FindCompanyByKeywordRequest>'+
                 '<sch:sortDirection>Ascending</sch:sortDirection>'+

                 '<sch:keyword>xyz</sch:keyword>'+

- Hide quoted text -

                 '<sch:searchBy>companyName</sch:searchBy>'+
                 '<sch:returnSearchNavigation>false</sch:returnSearchNavigation>'+
                 '<sch:orderBy xsi:nil="true" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/>'+
                 '<sch:searchNavigation>'+
                   '<sch:employeeSearchNavigation>'+
                   '</sch:employeeSearchNavigation>'+
                   '<sch:ownershipTypeSearchNavigation>'+
                   '</sch:ownershipTypeSearchNavigation>'+
                   '<sch:locationTypeSearchNavigation>'+
                   '</sch:locationTypeSearchNavigation>'+
                   '<sch:salesSearchNavigation>'+
                   '</sch:salesSearchNavigation>'+
                   '<sch:locationSearchNavigation>'+
                     '<sch:countryNavigation>'+
                       '<sch:countryNavigationValue>${#Project#countryNavigationValue}</sch:countryNavigationValue>'+
                       '<sch:stateNavigation>'+
                        '<sch:stateNavigationValue>${#Project#stateNavigationValue}</sch:stateNavigationValue>'+
                        '<sch:cityNavigation>'+
                          '<sch:cityNavigationValue>${#Project#cityNavigationValue}</sch:cityNavigationValue>'+
                        '</sch:cityNavigation>'+
                      '</sch:stateNavigation>'+
                    '</sch:countryNavigation>'+
                  '</sch:locationSearchNavigation>'+
                  '<sch:industrySearchNavigation>'+
                  '</sch:industrySearchNavigation>'+
                '</sch:searchNavigation>'+
              '</sch:FindCompanyByKeywordRequest>'+
            '</soapenv:Body>'+
          '</soapenv:Envelope>';
 
   Http h = new Http();
    HttpRequest req = new HttpRequest();
    req.setEndpoint('http://hapi.hoovers.com/HooversAPI-32');
    req.setMethod('POST');
    req.setBody(env);
    req.setTimeout(12000);
   
    Blob headerValue = Blob.valueOf(API_KEY);

    String authorizationHeader = 'BASIC ' + EncodingUtil.base64Encode(headerValue);
    req.setHeader('Authorization',authorizationHeader);

       
    HTTPResponse res = h.send(req);
    System.debug(res.getBody());
    }
}




  I tried with username and password also, even though i'm facing the same issue. Has anyone experienced anything similar to this?.   Any help must be appreciated.

Thanks Inadvance,
Satheesh
