HTML view in Web Dynpro

Question

Hello everybody,
   I'm developing an application and i need to display a html page inside a view.
   I'm developing in SAP NetWeaver Developer Studio, Version: 7.1.0 and UI element like iFrame, or IView does not exists.
   Do you have a suggestion, idea or advice?
Thank you,
Constantin

Hi Constantin,
For writing Html in iFrame u can use com.lowagie.text package and u can use these inbuild classes.
com.lowagie.text.BadElementException;
com.lowagie.text.Cell;
com.lowagie.text.Chunk;
com.lowagie.text.Document;
com.lowagie.text.DocumentException;
com.lowagie.text.Element;
com.lowagie.text.Image;
com.lowagie.text.Paragraph;
com.lowagie.text.Table;
com.lowagie.text.html.HtmlWriter;
com.lowagie.text.rtf.style.RtfFont;
first u have to create a method
like this
private void <method name>() {
          try {
               String filename = this.<name/id> + ".html";
               IPrivateView.IContextElement elem =
                    wdContext.createContextElement();
               elem.setRTFOutPut(getBytesFromFile(new File(filename)));
               final IWDCachedWebResource resource =
                    WDWebResource.getWebResource(
                         elem.getRTFOutPut(),
                         WDWebResourceType.HTML);
               //resource.setResourceName("HTML_inline.html"); original
               resource.setResourceName("HTML_inline"this.<name/id>".html"); 
               resource.setAttachement(false);
               resource.setReadOnce(false);
               wdContext.currentContextElement().setUrl(resource.getAbsoluteURL());
          } catch (WDURLException e) {
               logger.errorT(e.getMessage());
               wdThis.wdGetPortfolioMessagesInterface().reportError(
                    "<custom message",
                    <Parameters>,
                    true);
               //wdComponentAPI.getMessageManager().reportException(new WDNonFatalException(e), false);
               //e.printStackTrace();
than for writing in iframe create a method like this.
private void generateIframe() {
          String newLine = "";
          Document doc = new Document();
          String filename = this.<name/id> + ".html";
          HtmlWriter html = null;
          try {
               RtfFont rtffontN = new RtfFont(FONT, FONT_SIZE, RtfFont.NORMAL);
               RtfFont rtffont = new RtfFont(FONT, FONT_SIZE, RtfFont.BOLD);
               RtfFont headfont = new RtfFont(FONT, 12, RtfFont.BOLD);
               DataOutputStream ds =
                    new DataOutputStream(new ByteArrayOutputStream());
               ds = new DataOutputStream(new FileOutputStream(filename));
               html = HtmlWriter.getInstance(doc, ds);
               //html = HtmlWriter.getInstance(doc,new FileOutputStream(filename));
               doc.open();
//now here u can use the classes like Cell ,table,Document for writing the html code in the iFRAME .for more information on this u can refer this site all the api documentation is given here.
http://itext.ugent.be/library/api/
after writing the html code using com.lowagie.text package.
at the end call the method which u declared earlier to this method.and create a context element URL map it to the source of Iframe in properties view.
Please Reward points for an helpfull answer.
