java - Second JOptionPane goes to behind all programs -

in java agent if put 2 joptionpane,one after other, second 1 goes behind applications opened.

i tried

• change null this; this:

  the method showmessagedialog(component, object, string, int) in type joptionpane not applicable arguments (javaagent, string, string, int)" 

• get parent component possible. didn't work
• set setalwaysontop permission in java.policy file,also didn't work
• my class extends class need, can't extend javax.swing.jdialog.

the code use is:

public class javaagent extends agentbase{  private static int erros=0; private static int count=0;  public int geterros(){return erros;} public int getcount(){return count;}  public void notesmain() {     system.out.println("\n\nstart of agente!");      try {          session session = getsession();          database db = session.getcurrentdatabase();         view vw = db.getview("vwtodas");          jfilechooser fc = new jfilechooser();         //get file file chooser              /* filter filereader through buffered read read line @             time */             bufferedreader bufread = null;              try{                 //read file                          //work in file                 }              }catch(ioexception a){                 joptionpane.showmessagedialog(null,"problems reading file!","problems!",joptionpane.information_message);             }finally{                 try{                     bufread.close();                 }catch(ioexception b){                     joptionpane.showmessagedialog(null, "problems closing file!", "problems!", joptionpane.information_message);                 }             }              system.out.println("\n\nend of agente!");              joptionpane.showmessagedialog(frame,"documents sent: " + count + "\nerrors during import: " + erros +   "\ntotal: " + (count+erros),"erro",joptionpane.error_message);         }             } catch(notesexception e) {         e.printstacktrace();     }  } 

}

any idea?

you can create jframe, set on top , pass jframe in parent component of joptionpane:

jframe parentframe = new jframe(); parentframe.setalwaysontop(true); joptionpane.showmessagedialog(null, "problems closing file!", "problem!",      joptionpane.information_message); 

alternatively, if have parent component available, should use joptionpane's parent component
