Problem occurs due to combine the code.....

[Navdip]

Hi all..
i am developing a project in java using swings and JApplets which has different modules for different purposes. in this project there is a module named "event" which has three button..and they have their well defined set of action.... Because project is very large so i had developd them separately ...and now they are working and gives proper output..but when i combined them with main project...it doesn't give any output although there is not any error.....so please know me how to tackle it..??

Your question is like saying: I built a real fast car myself: the steering engine
works, the wheels can rotate and I can even open and close the windows; the
car just won't drive; what could be the problem?

You should do some unit testing: the input for one module can be the output of
another one; test that communication for all modules that do interact. Slowly
build up the combination of your modules and test whether or not it functions
properly; only then proceed to the next module(s) integration.

kind regards,

Jos

Hi josah
there is no IPC in project so no module can interact with another module...i have put some print statements to debug it but they do not execute after ocurance of following statements..
JFileChooser filechooser=nul l;
filechooser = new JFileChooser();
i.e control doesn't move after these statements.....

What happens before those statements then and where is the code for that?

 else if (e.getSource() == liveButton)
      {
		  JOptionPane.showMessageDialog(null,"Clicked on live-Button","Honey well",1);//Debug
        liveData = true;
      }
    }

    private void browseFile()
    {
		JOptionPane.showMessageDialog(null,"INSIDE Browse fxn 01","Honey well",1);//debug
		events.append("\tinside Browse function");//debug1
      JFileChooser filechooser=null;

      filechooser = new JFileChooser();
            events.append("file chooser  "+filechooser);
      events.append("Creation of file chooser");//debug2
      JOptionPane.showMessageDialog(null,"INSIDE Browse fxn after creating filechooser object 02","Honey well",1);//debug3
      //filechooser.setFileSelectionMode(JFileChooser.FILES_ONLY);

      filechooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);//Debug (nav)
      JOptionPane.showMessageDialog(null,"INSIDE Browse fxn after choosing file type 03","Honey well",1);//debug4

      filechooser.showOpenDialog(this);//debug (nav)
      //if(filechooser.showOpenDialog(this) == JFileChooser.CANCEL_OPTION)
      //  return;

      evtFile = filechooser.getSelectedFile();

      if(evtFile == null || evtFile.getName().equals(""))
      {
        JOptionPane.showMessageDialog(this, "Invalid Event Log Filename", "Invalid Filename", JOptionPane.ERROR_MESSAGE);
      }
      else
      {
        parseFile(evtFile);
      }
    }

this code is working when i run it as individually but in main project in create problem in "debug 2" may it possible it is unable to create File chooser' object..i am sending u just a part of module, the whole module is impossible to send..

Looks like I edited that mispel too late.
I meant what does the logging output show?

it will call the parse function atlast in which we have passed the Binary file that would be choosed from some location..and the parse function parse it according structure and display some data in JTextArea...pro blem is arising when we create object of JFileChooser class...
