我认为问题是您没有在网址中添加适当的连接后缀。

点击链接可以解决您的问题:http://www.blackberry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800451/800563/What_Is_-_Different_ways_to_make_an_HTTP_or_socket_connection.html?nodeid=826935&vernum=0

您还可以使用以下示例代码:

private static String getConnectionString(){
    String connectionString="";
    if(WLANInfo.getWLANState()==WLANInfo.WLAN_STATE_CONNECTED){
        connectionString=";interface=wifi";
    }

     else if((CoverageInfo.getCoverageStatus() & CoverageInfo.COVERAGE_MDS) == CoverageInfo.COVERAGE_MDS){
         connectionString = ";deviceside=false";
    }
        else if((CoverageInfo.getCoverageStatus() & CoverageInfo.COVERAGE_DIRECT)==CoverageInfo.COVERAGE_DIRECT){
            String carrierUid=getCarrierBIBSUid();
            if(carrierUid == null) {
                connectionString = ";deviceside=true";
            }
            else{
                 connectionString = ";deviceside=false;connectionUID="+carrierUid + ";ConnectionType=mds-public";
                }               
            }
     else if(CoverageInfo.getCoverageStatus() == CoverageInfo.COVERAGE_NONE)
        {

        }
    return connectionString;
    }
