Opening a PDF File from WebDynpro

Question

Hello Everyone,
I have a Webdynpro project and need to create a link on one of the views to display a .PDF document.
1.  Where should I store the PDF document within the webdynpro project?
2.  How do I open the PDF file?
I've created a link with action on the view and just need to know how to open it.
Thanks in advance for your help.
Mike

Hi Mike,
You can try one of the following methods:
Method 1:
1. Create a context attribute (say pdfsource) of type binary.
2. Create a file download control
3. Attach this attribute to the data property of file download control.
4. In the init method of the view or in some other method store the content of the pdf in the context attribute. And do the following code
     IWDAttributeInfo attInfo = wdContext.currentContextElement().node().getNodeInfo().getAttribute("pdfSource");
     ISimpleTypeModifiable type = attInfo.getModifiableSimpleType();
     IWDModifiableBinaryType binaryType = (IWDModifiableBinaryType) type;
     binaryType.setFileName("Test.pdf");
     binaryType.setMimeType(WDWebResourceType.PDF);
5. Now on click of File Download link, it will ask for "Open", "Save", or "Cancel" dialog box. You can choose open to open as a pdf document.
Method 2:
1. Write an action on click of the button or so.
2. In that action get the contents and store it in an byte array and open the pdf file directly as follows.
     byte[] PDFbytes = <source string>.getBytes();
     if(PDFbytes!= null) {                                IWDCachedWebResource pdffile= WDWebResource.getPublicCachedWebResource(                    PDFbytes ,                                 WDWebResourceType.PDF,                            WDScopeType.CLIENTSESSION_SCOPE,               wdThis.wdGetAPI().getComponent().getDeployableObjectPart(),
                "Some Title");                             wdComponentAPI.getWindowManager().createNonModalExternalWindow(pdffile.getURL(), "Some PDF").open();
Thanks and regards
