Hi All,

I need to consume a webservice(developed in Java) in C#.net.

In this I need to pass the parameter name as db:hostname in request from c#.net to Java.

XML

<soap:envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:dev="XXXX/devicemanagement/device" xmlns:com="XXXX/ws/common" xmlns:com1="XXXX/types/common">
   <soap:header />
   <soap:body>
      <dev:adddevicesrequest xmlns:db="XXXX/deviceattribute/basicinfo" xmlns:dauth="XXXX/deviceattribute/authentication" xmlns:dgauth="XXXXX/devicegroupattribute/authentication">
        <dev:device>
              <dev:attribute>
                    <com:name>db:HostName</com:name>
                    <com:stringvalue>192.168.200.101</com:stringvalue>
              </dev:attribute>
              <dev:attribute>
                    <com:name>db:DisplayDeviceName</com:name>
                    <com:stringvalue>d01</com:stringvalue>
              </dev:attribute>
              <dev:attribute>
                      <com:name>db:ModelCode</com:name>
                      <com:stringvalue>ModelCode01</com:stringvalue>
               </dev:attribute>
               <dev:attribute>
                      <com:name>db:SerialNumber</com:name>
                      <com:stringvalue>12301</com:stringvalue>
               </dev:attribute>
        </dev:device>
      </dev:adddevicesrequest>
   </soap:body>
</soap:envelope>




<big>When I pass parameter as "db:hostname" from c# to java, it is getting encrypted at java end as "db_x003A_hostname" which means colon (":") is getting converted to " _x003A" at java service. This results an error as "invalid parameter name".</big>

Please help me in resolving this error.

Thanks in advance for your help.

Solution 1

You need to use UTF8 Encoding.
All others will fail.

Hi Mr.TorstenH,

Thanks for your help
Please guide me how to pass this UTF8 encoded parameter from c# client to Java webservice.
I don't have any control on Java web service.

Request you to share me skeleton/pseudo code

TorstenH. 22-Apr-14 1:59am

try this:

byte[] bytes = Encoding.Default.GetBytes(myString);
myString = Encoding.UTF8.GetString(bytes);

That should bring your String into UTF-8 encoding (I'm not into C#, so you might need to check if that's correct).
Please also check if the String is put in correctly in the soap-request and - if possible - if it is extracted correct on the other side.

+it should be in request header

Solution 2

Colon is not a valid character inside a element name. Colon is used to pair the namespace and the element name. Here if you want the Db to go along then you might need to add it as a namespace.

C#

// Serialize the hostname field as an attribute with the given namspace
[XmlAttribute( Namespace ="www.db.com")]
public string hostname;

Hi Guruprasad,

Thanks for your help

I tried your solution but it didn't resolved my issue,
To be more clear,if you see above request "I need to pass parameter values like "db:hostname","db:DisplayDeviceName".... and so on.. from C# client to Java websercice"

Please help me at earliest possible..

Hi Balu,

Can you show me the code where you are creating this XML ?
