java - passing data from one frame and setting it in textfield in another frame retrieving corresponding data from database -

i working on netbeans project (java swings) using mysql @ ground. got struck in particular scenario.

i working jtable in 1 frame, frame1 row has selected on 'onclick' action event.

the corresponding data table in background in mysql retrieved , data passed on frame, frame2 data set jtextfield.

the table in frame1 contains few selected tuples of whole table maintained in database.

the following code snippets used :: database table name db_table

1- select data table in frame1

public static string table; public static int row; private void jtable1mouseclicked(java.awt.event.mouseevent evt)                     {                                          // todo add handling code here:     jbutton3.setenabled(true);     row = jtable1.getselectedrow();     table = (jtable1.getmodel().getvalueat(row,0).tostring()); } 

2- action event on button redirect frame2

private void jbutton4actionperformed(java.awt.event.actionevent evt)  {                                              // todo add handling code here:     frame2 ac =new frame2();     jdesktoppane1.add(ac);     try {         ac.setselectedrow(table);     } catch (exception e) {         // logger.getlogger(showp1.class.getname()).log(level.severe, null, ex);     }     ac.setvisible(true); }  

3- method in frame2

void setselectedrow(string table) {     try {         //resultset resultset = null;         system.out.print(table);          rs = pst.executequery("select * db_table attr="+ table +"");         //system.out.print(table);         while (rs.next()) {             system.out.print(table);             //jtextfield1.settext(resultset.getstring(1));             //system.out.print(table);             jtextfield1.settext(rs.getstring("attr"));         }     } catch (sqlexception ex) {         logger.getlogger(addclient.class.getname()).log(level.severe, null, ex);     } } 

the data being printed in output console not being stored in text field in frame2...

hope clear problem

any suggestions appreciated..
