Calling a web service using https post

[Suresh Ram]

Hi,

I am using websphere6.0 and i did the following to call a https webservice. I have a cert.pfx certificate that was given by the service provider.

1. I downloaded the following unrestricted policy files from IBM local_policy.jar and US_export_policy.jar and replaced the files present in the ....\runtimes\base_v6\java\jre\lib\security directory.
2. Opened the ikeyman present in the ....\runtimes\base_v6\bin\ folder.Selected Open-->Keydatabase type as PKCS12, file name as the cert.pfx, gave the file location, Clicked OK. It challenged for a password. I entered the password of the PFX file. The certifcate got loaded under personal certficate. Then i selected the certificate and imported it to the CACERTS store.
3. Then i wrote the following code.

				MySocketFactory mySocketFactory = new MySocketFactory(null);
				byte[] requestXmlBytes = requestXml.getBytes();
				SSLSocket theSocket = null;
				HttpsURLConnection httpConn =  null;
				URL url = new URL(urlString);
				httpConn = (HttpsURLConnection) url.openConnection();
				try {
					KeyStore keyStoreKeys;
					KeyManagerFactory keyMgrFactory;
					SSLContext sslContext;
					keyStoreKeys = KeyStore.getInstance("PKCS12");			
					keyStoreKeys.load(new 					FileInputStream("C://cert.pfx"),"password".toCharArray());
					keyMgrFactory = KeyManagerFactory.getInstance("IbmX509");
					keyMgrFactory.init(keyStoreKeys, "password".toCharArray());
					sslContext = SSLContext.getInstance("SSL");
					sslContext.init(keyMgrFactory.getKeyManagers(), null, null);
					SSLSocketFactory socketFactory = sslContext.getSocketFactory();
					
					httpConn.setSSLSocketFactory(socketFactory);
				} catch (Exception e) {
					e.printStackTrace();
				}
		        // Set the appropriate HTTP parameters.
		        httpConn.setRequestProperty( "Content-Length",
		                                     String.valueOf(requestXmlBytes.length ) );
		        httpConn.setRequestProperty("Content-Type","text/xml; charset=utf-8");
				  httpConn.setRequestProperty("SOAPAction",soapAction);
		        httpConn.setRequestMethod( "POST" );
		        httpConn.setDoOutput(true);
		        httpConn.setDoInput(true);
		        
		        // Everything's set up; send the XML that was read in to b.
		        OutputStream out = httpConn.getOutputStream();
		        out.write( requestXmlBytes );    
		        out.close();
		        
		        InputStreamReader isr = new InputStreamReader(httpConn.getInputStream());
		        BufferedReader in = new BufferedReader(isr);

		        String inputLine;

		        while ((inputLine = in.readLine()) != null)
		            System.out.println(inputLine);

		        in.close();

I am getting an exception: javax.net.ssl.SSLHandshakeException: unknown certificate;

Do i need to do anything further? Am i proceeding correctly? Any help is really appreciated.

Thanks in advance,
Ram
