Hi Ischia,

if you don't want to use PDF Interactive Forms perhaps this project should be useful for you.

Project <b>FOP</b> (http://xmlgraphics.apache.org/fop/) to export any context node in PDF format, after importing and using a plugin.

Hope this help you.

Hi Gianluca;

Thanks a lot for you replay. The solution you propose is very innovative. It will be a challenge!

I'm already working in that. Let's see how it ends...

Last comment: your idea makes me feel like if it wasn't possible to convert Iviews contents into a pdf file without using forms. Maybe webdynpro does not support that functionality.

Does everybody agree with me or have any solution?

Hi Ivan,

I've tested the FOP project by myself into WD application and I could say that it's a valid alternative to Interactive Forms.

The only issue is that there isn't a UI control for FOP in NWDS so you must insert the plugin into WD project and add some code to use it.

If you like this solution, can you give me some forum points please. I appreciate...

Regards.

Grazie gianluca!,

I also think it would be a fine alternative, even thought i haven't taken a deep investigation on it, since I didn't found out how to insert the uncompressed .tar.gz file I downloaded into a WD plugin.

Could you guide me please in more detail steps, including an example of the code you used?

Forum points for you thanks!

PD: If you find useful to use my email address please do it: alfredogarciarios@gmail.com

Hi Ivan,

you must add all files of the FOP under the lib folder in Navigator Perspective.

The files are in the attachment that I sent you by email.

this is an example of Java function that use FOP:

public int CreaFilePdf( )
  {
    //@@begin CreaFilePdf()
	////////////////////////////
	int ret = 0;
	byte[] pdfFoXMLFile = null;
	byte[] pdfFile;

	String fileName = new String();
	fileName = "Equipment.pdf";
	String foText = new String();

	////////////////////////////
	try {
		foText = this.toFoXML();
		wdContext.currentContextElement().setFoText(foText);
		pdfFoXMLFile = foText.getBytes("UTF-8");

		OutputStream outFo = new java.io.FileOutputStream("Equipment.pdf.fo");
		
		try {

  		driver.setRenderer(Driver.RENDER_PDF);

			out.close();
		}

	// Get some byte array data
	pdfFile = getBytesFromFile(file);
	
	
	//pdfFoXMLFile = this.toFoXML().getBytes("UTF-8");
	// create a cached Web Dynpro XLS Resource for the given byte array and filename
	
	cachedPdfResource = this.getCachedWebResource(pdfFile, fileName, WDWebResourceType.PDF);

	// Store URL and filename of cached excel resource in context. 
	if (cachedPdfResource != null) {
	  wdContext.currentContextElement().setPdfFileURL(cachedPdfResource.getURL());
	  wdContext.currentContextElement().setPdfFileName(cachedPdfResource.getResourceName());

	} else {
	  ret = 1;
	}
  }
  catch (WDURLException e) {
	  ret = 1;
  }
  
  
///////////////////////////////
	} catch (FileNotFoundException e1) {

	} catch (FOPException e3) {
		// TODO Auto-generated catch block
		e3.printStackTrace();
	}
    

	

    
    /////////////////////////////
	return ret;
    //@@end
  }

If RET is 0 the generation is OK!!

Hello Gianluca, great job!

I must ask you a last question, since I have used your code and I get some errors.

Could you please be so nice to tell me all imports stataments? And also from which context do you write this method CreaFilePdf()?

I say it because I'm getting this erros also:

this.toFoXMK

this.getBytesFromFile

this.getCachedWebResorce

Thansk very much,

Ivan

Hi Ivan,

I post you the code.

Hi Vito thanks for you replay,

Unfortunately the link you suggested guides the reader to use Adobe Interactive Forms, and that's exactly what I'm requested to avoid.

Any other ideas would be very welcame!
