asix2 client and windows based webservice interaction for unicode data

[Taggu Gupta]

Hi ,

I’ve got an application which is deployed on Tomcat 6.0.29. I’ve created and deployed a webservice on IIS Web Service. The Web Method in this Webservice is used to get the file metadata (last_modified , last_accessed, last_created) from the Windows filesystem. The axis2 client is in java (jdk 1.6). If the filename path is in English then everything is OK. But, if one of the path component is in non-English(Chinese) then I get the following exception



Caused by: org.apache.axis2.AxisFault: Connection reset; nested exception is:

The code in java looks like :





String xmlFile;

try {

FileAttribServiceStub stub = new FileAttribServiceStub();

FileAttribServiceStub.GetFileProperties request = new FileAttribServiceStub.GetFileProperties();

byte[] b = file.getCanonicalPath().getBytes();

String path = new String(b,"UTF-8");

//request.setFileName(file.getCanonicalPath());

request.setFileName(path);

// send and get the response

FileAttribServiceStub.GetFilePropertiesResponse response = stub //IT THROWS AN EXCEPTION HERE

.GetFileProperties(request);



String fileAttribXML = response.getGetFilePropertiesResult();



xmlFile = "<?xml version=\"1.0\" encoding=\"utf-8\"?>";

xmlFile = xmlFile + "\n"

+ "<string xmlns=\"http://www.digitalmountain.com/webservices/\">";

xmlFile = xmlFile + "\n" + fileAttribXML;

xmlFile = xmlFile + "\n" + "</string>";





The Webservice code in .NET is :

sing System;

using System.Collections;

using System.ComponentModel;

using System.Data;

using System.Diagnostics;

using System.Web;

using System.Web.Services;

using System.Text;

using System.IO;



namespace WSFileProperties

{

/// <summary>

/// Summary description for Service1.

/// </summary>

///

public class FileAttribService : System.Web.Services.WebService

{

public FileAttribService()

{

//CODEGEN: This call is required by the ASP.NET Web Services Designer

InitializeComponent();

}



#region Component Designer generated code



//Required by the Web Services Designer

private IContainer components = null;



/// <summary>

/// Required method for Designer support - do not modify

/// the contents of this method with the code editor.

/// </summary>

private void InitializeComponent()

{

}



/// <summary>

/// Clean up any resources being used.

/// </summary>

protected override void Dispose( bool disposing )

{

if(disposing && components != null)

{

components.Dispose();

}

base.Dispose(disposing);

}

}

return sb.ToString();

}



}







}





I’ve already installed the language path on my XP box. How should I go on resolving this.



Thanks,
