first.jsp

I have to add another new button “send” in the first.jsp page and I have to call second.jsp when I click “send” after selecting values from the list box and these selected values should be passed to the second.jsp. The action page1.jsp should not be changed but the second.jsp page should be open in a pop-up window when I click send button.

Can any one please tell me how I can achieve this, if possible could you post some sample code
