How to close OA page by clicking on Submit_Button ?

Question

Hi,
I have a requirement to close OA page when the user clicks on Submit_Button(save) on the same page. But we have a logic in CO(processFormRequest) to do some actions when the user clicks on Submit_Button, so I want to close the OA page once those actions completed in Submit_Button(save) logic. How can I achieve this requirement, please help me.
Below is the code in Submit_Button(save)
public void processFormRequest(OAPageContext pageContext, OAWebBean webBean)
super.processFormRequest(pageContext, webBean);
OAApplicationModule am = pageContext.getApplicationModule(webBean);
if(pageContext.getParameter("save") != null)
OAMessageTextInputBean notesBean = (OAMessageTextInputBean)webBean.findIndexedChildRecursive("Notes");
String scRecordId = pageContext.getParameter("searchTempId");
String invNo = pageContext.getParameter("InvNo");
String idFlag = pageContext.getParameter("IdFlag");
String value = (String)notesBean.getValue(pageContext);
Serializable param[] = {
scRecordId, value, invNo, idFlag
am.invokeMethod("getNotes", param);
}

First of all thanks to Shree to respond to my question.
I didnt try as you suggest bcz I think it will not work to my requirement. But I have tried your solution directly in the Save button logic but it is not working.
Let me explain my entire requirement:
I have one search page, in that we have Notes column with notes image in Search Results.
When the user clicks on that Notes Image, it is going to open one new page.
In that new page we have one Textbox(MessageTextInput), One Save(Submitbutton), Cancel(Button).
User will type some notes in the Textbox and then he will click on Save then the data gets saved into particular table column and user will click cancel button to close that page.
Then user will click on Apply button in the main page then there are some actions going to perform.
Now user wants to close that page when user clicks on Save button after entering the notes in Text box.
I have tried following coding in Save button logic.. at the end of the save button logic
pageContext.putJavaScriptFunction("keyListener", "function keyListener(){window.close();}
OASubmitButtonBean cb=(OASubmitButtonBean)webBean.findChildRecursive("save");
cb.setOnClick("keyListener()");
and
pageContext.putJavaScriptFunction("keyListener", "function keyListener(){window.close();}");
OAWebBean body = pageContext.getRootWebBean();
if (body instanceof OABodyBean)
body.setOnKeyPress("keyListener()");
but no luck
Please advice me...
