            btnLoad.setText("Load");
            btnLoad.addActionListener(this);
        }

    public Vector<String> getAlias(){

                str.add(aliasName);
            }

        } catch (KeyStoreException e) {

        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return str;
    }

    @Override
    public void actionPerformed(ActionEvent arg0) {
        // TODO Auto-generated method stub
        Object obj = arg0.getSource();
        if(obj == btnLoad){
            String alias = (String)getListCertificate().getSelectedValue();
            String password = getPassword().getText();

        }
    }

}  //  @jve:decl-index=0:visual-constraint="294,19"

I want to call that class from JSP.
Thanks.

When I click button on the browser, I want to call frame.

Launch the frame directly from an HTML link (or button) using Java Web Start.
