Display a iframe (HTML widget in oaf page) in  oaf page using CO Extension

Business case:  display a iframe (HTML widget in oaf page) at the bottom of oaf page

(using this you can display any HTML content/ PDF/JSP page inside the HTML widget)

1. Turn on the personalization by setting the appropriate profile value from system administrator
2. Navigate to page -> Personalize page as below

3. Click on the personalize pencil icon for item which has CO associated with it 

4)    Here you can see controller class name is ProjectProfileCO

Now we need to create a custom class file and extend this class in our custom class file so that we can append our custom logic to the seeded OAF page. 

 Note: Make sure you note down the path where you are doing the personalization  , if class file has any error you wont be able to navigate to page where you are doing personalization   and eventually you wont be able to disable the personalization  , if you have personalization  path you can navigate to functional administrator and disable or edit the personalization  .

5) Create a class file with any name as below and copy this class file in server on the location as given in package. Make sure the location is named correctly , copy the file in $JAVA_TOP under specific folder structure.

Note: You can also use JDeveloper to create java file , this can help if you want to access any methods associated with standard java code, in order to do this you must import the required java class files in JDeveloper from oracle server e.g.  You may need to import classes located at oracle.apps.fnd.framework.* 

Below is the controller class file code , based on requirement you can either display it in PFR/PR to render on action or while page is rendered.

 public void processRequest(OAPageContext pageContext, OAWebBean webBean) {

  super.processRequest(pageContext, webBean);

  try {

  

//  in case you need to display header to the i-frame use below //

 //  OAHeaderBean Bean = (OAHeaderBean) createWebBean(pageContext, HEADER_BEAN);

   try {

    OAApplicationModule am = pageContext.getApplicationModule(webBean);

     pageContext.writeDiagnostics(this, "xxecm getting project_id value from opentext.oracle.apps.xxxecm4o_bp.costingsheet.webui.XxxecmProjectsCO51.class", OAFwkConstants.EXCEPTION);

      if (pageContext.getSessionValueDirect("TRX_PROJECT_ID") != null) {

     pageContext.writeDiagnostics(this, "xxecm inside if condition", OAFwkConstants.EXCEPTION);

             xx_val =

                pageContext.getSessionValueDirect("TRX_PROJECT_ID").toString();           

            }

   

if (pageContext.isLoggingEnabled(OAFwkConstants.EXCEPTION)) {

     pageContext.writeDiagnostics(this, "[TestCO]processRequest():- xxecm project ID value is "+xx_val, OAFwkConstants.EXCEPTION);

    }

   } catch (Exception e) {

    pageContext.writeDiagnostics(this, "Exception ocurred in getting am xxx:" + e,

     OAFwkConstants.STATEMENT);

   }

   String xx_msg_type;

   xx_msg_type = "Projects";

   //  pageContext.putSessionValue("211", xx_val);

   String final_url;

   final_url = "OA.jsp?page=/opentext/oracle/apps/xxxecm4o/bws/webui/workspacePG&xxotBOId=" + xx_val + "&xxotBOType=Projects&addBreadCrumb=Y&retainAM=Y";

   OAHTMLWebBean showWorksapce = (OAHTMLWebBean) createWebBean(pageContext, HTML_WEB_BEAN, null, "IFRAME");

   showWorksapce.setHTMLAttributeValue("src", final_url);

   //pdfBlob

   // p_output

   showWorksapce.setHTMLAttributeValue("width", "100%");

   showWorksapce.setHTMLAttributeValue("height", "65%");

   pageContext.getPageLayoutBean().addIndexedChild(showWorksapce);

  } catch (Exception e) {

   pageContext.writeDiagnostics(this, "Exception ocurred in class swapnil:" + e,

    OAFwkConstants.STATEMENT);

  }

 }

 /**

  * Procedure to handle form submissions for form elements in a region.

  *

  * @param pageContext

  *            the current OA page context

  * @param webBean

  *            the web bean corresponding to the region

  */

 public void processFormRequest(OAPageContext pageContext,

  OAWebBean webBean) {

  super.processFormRequest(pageContext, webBean);

 }

}

6) Copy the class file to server  and compile using javac command and create the .class file

Then navigate to personalization page and enter the custom class file name along with full path in $JAVA_TOP ( don’t enter the path from root folder) . 

As you can see the below page is integrated in OAF inside the iframe
