Hello,
When i am encrypting a string (One way hashed) using SHA algorithm, the output differs from two different platforms.
When done in windows, an extra CR (CR LF) character is appearing but when done in linux box only LF character is appearing in between the output encrypted value.
FYI - CR (enter) LF(Space)
This leading me with issues in further process of application.
Kindly help for the same

Ho All,
I'm creating a TCP server with which I'll receive few strings.
First a file path
Second a message
Third another message
My code is:
String str;
while ((str = rd.readLine()) != null) {
System.out.println(str);
String file = str.toString();
.
..
.
.
while(something)
{
while(something new)
{
if(str.equalsignorecase("Google"))
{
System.out.print("My Yahoo");
}
else if(str.equalsignorecase("yahoo"))
{
System.out.print(My Google);
}
}
}
}
rd.close();
socket.close();
In this program, I'm able to access the first string but not getting the second string on
server.
How can I use String str multiple times sent by a TCP client?
Thanks!

I want to create a file path from a string.
My code is:
String files = "";
if(files!= null)
{
InputStreamReader input = new InputStreamReader(System.in);
BufferedReader reader = new BufferedReader(input);
files = reader.readLine();
File sourcefile = new File(files);
System.out.print(sourcefile.toString());
StringBuilder sURL = new StringBuilder("file:///");
sURL.append(sourcefile.getCanonicalPath().replace('\\', '/'));
}
But it is returning me project path in place of file path.
How can I do it?
Please Suggest!

package Haitham
import java.io.IOException;
import java.net.URISyntaxException;
import java.rmi.RemoteException;
import java.util.Properties;
import java.util.logging.Logger;
import javax.jms.Connection;
import javax.jms.ConnectionFactory;
import javax.jms.JMSException;
import javax.jms.MessageProducer;
import javax.jms.Session;
import javax.jms.TextMessage;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
public class TracingMessages
{
public static String Send_MVRI_Messages(String qname,String msg) throws IOException, URISyntaxException {
String body="";
try
{
Context init =TracingMessages.getInitialContext();
javax.jms.Queue destination = (javax.jms.Queue) init.lookup("/queue/" +qname);
ConnectionFactory connectionFactory = (ConnectionFactory) init.lookup("ConnectionFactory");
Connection connection = connectionFactory.createConnection();//
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
MessageProducer producer = session.createProducer(destination);
TextMessage message = session.createTextMessage();
message.setText(msg );
connection.start();
System.out.println("connect strat");
producer.send(message);
body = message.getText();
session.close();
connection.close();
}
catch (Exception e)

return(e.toString());
}
return body ;
}
public static Context getInitialContext () throws JMSException,NamingException,RemoteException
{
Properties prop = new Properties();
prop.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
prop.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces");
prop.setProperty("java.naming.provider.url", "127.0.0.1:1099");
Context context = new InitialContext(prop);
return context;
}
}
Then i converted to DLL file to send message from C# to jboss,
everything are goo,so i can send message from c# windows application to jboss server
but if i use the same DLL file inside web application i got the following error:
javax.naming.NoInitialContextException: Cannot instantiate class: org.jnp.interfaces.NamingContextFactory [Root exception is java.lang.ClassNotFoundException: org.jnp.interfaces.NamingContextFactory
My question Why???

public class Main {
public void runTest() throws Exception {
InitialContext ctx = new InitialContext();
ExampleSessionBeanRemote bean =
