On clicking a button run external class which refrances main application

Question

I have a reader ReadXML and a Jframe Cpass, on clicking a button on Cpass, an new filechooser opens, this then fills the input jtextfiled12 . When clicking "load" button on cpass I need to send jtextfiled12.getText() to ReadXML (this runs, and updates mank text fields on cPass)... but I cant reference from a static context Cpass>>ReadXML>>Cpass.... so having a problem
relevant cPass in cPass.java:
public class Cpass extends javax.swing.JFrame {
public static void main(String args[]) {
Cpass C = new Cpass();
     C.show();
public String getIn() {        return this.jTextField12.getText();         }
relevant ReadXML in ReadXML.java:
public class ReadXML {
private void ReadInXML() throws IOException {
     String XmlInText = Cpass.getIn();
          BufferedReader allData8 = new BufferedReader(new InputStreamReader
(new FileInputStream(new File( XmlInText)),"UTF8")); }

Answer 1

but since cpass is already running from cpass, i cant reinitialise it, I need to used the insatance that is already shown, since it contains the infomation needed to pass to readXML
public static void main(String args[]) {
   Cpass C = new Cpass();
   C.show();
   }When selectinfg a button on C (which selects the file location), that then opens readXML, I cant open a new version of Cpass (since this wont contain the infomation, eg the file the user has just chosen)
I need to run Cpass
Click a button that selects a file
then file location is set in a text feild on Cpass
on selecting "load" on Cpass, this runs readXML.java
*readXML some how gets the file location from Cpass (which is still C.show();)
the XML is read, and sent back to Cpass via:
          public String[] getStrAllData() {
                  return this.arrayXML;
         }One way arround thios is to copy the readXML function into Cpass but thats just messy
Another would be to write out a "cookie" type file that saves the location, then readXML can use this .. less messy, but not what I wanted.
