Hi,

i created a basic Java Desktop Application and created a button, jButton1 and in the Action Performed
function i wrote the below code...

    private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {

                Test t = new Test();
                System.out.println("Starting FTP...");
                t.main(null);
                System.out.println("FTP Completed...");
       
    }

But on clicking the button it hangs at the following location :-
                        ftp.connect( server ); in Utilities class.


But if i compile and Run Test.java , it works perfectly fine.
i don't know why the same code hangs in jButton1ActionPerformed() function.


please help...


package ftpclient;

public class Test
{
    public static void main(String args[])
    {
        Utilities utilities = new Utilities();
        String server = "snv";
        String username = "xlc";
        String password = "pass";
        String remoteFolder = "testftp";
        utilities.targetFileWithFolder = "C:\\1\\Test\\xyz.zip";
        String localZipFileWithPath = utilities.targetFileWithFolder;
        utilities.putFilesToServer(server, username, password, remoteFolder, localZipFileWithPath);
       
    }

}
