             System.out.println(e);
        }


}

public void actionPerformed(ActionEvent ae)
  {

	String value1=text1.getText();
				
	if(ae.getSource() == btntrans)
	{
 
        
 try {
         FileInterface fi = new FileImpl("FileServer");
         Naming.rebind("//192.168.1.2/FileServer", fi);
      } 
         catch(Exception e) {
         System.out.println("FileServer: "+e.getMessage());
         e.printStackTrace();

		System.exit(0);
	}
}
     public static void main(String args[])
  {
 	transfer t=new transfer();
	t.show();
  }
}

Now i need to take IP adress from user & pass it to Naming.rebind("//192.168.1.2/FileServer", fi); instead of 192.168.1.2.
the ip adress is stored in Value1.
how do i pass tht value to Naming.rebind("//192.168.1.2/FileServer", fi); * i need user input ip adress instead of 192.168.1.2.
thanx fr any kind of assistance in advance

Most simple without any checks for entry validity will be [icode]Naming.rebind(text1.getText())[/icode]. More complex with validation will do more less same [icode]Naming.rebind(validate(text1.getText()))[/icode] where you send what ever retrieved from user to validation method that will check that string is in appropriate format (4 sets of numbers berween 0-255)

Re: how to pass values in java 80 80

hey thnks a lot....it did work...!!

Re: how to pass values in java 80 80

hey even

Naming.rebind("//"+value1+"/FileServer", fi);

also works...
since am storing the textbox value in Value1

String value1=text1.getText();

bt thnks fr d reply.. :)

Re: how to pass values in java 80 80

Instead of using this

String value1=text1.getText();

you should use setter and getter methods.

setIP(text1.getText());
//do not forget value1 declaration at the start of your code
//as private String value1;

private void setIP(String string){
    value1 = string;
}

public String getIP(){
    return value1;
}
