%pdf error in downloading pdf from Function module

[praveenkumar_kadi]

Hi,

I am trying to download pdf from a LinkToaction UI element.

I recieve %pdf" error when trying to download using below code. from backend perspective ABAPer said they are able to download PDF from ABAP program. Lokks like I am doing some mistake somewhere in below code.

From the backend, pdf is coming in a table in the form of SOLI-Text Line (TLine - SO_TEXT255)

In webdynpro I am tried to take each line from that table and attched to a IWDResource as below.

Please correct me if anything wrong here to get out of %pdf" error.

IModel_Pdf_FileNode Model = wdContext.nodeModel_Pdf_File();
IPDFElement pdf = wdContext.nodePDF().currentPDFElement();
if (Model != null && Model.size() > 0) 
 {
ByteArrayOutputStream baos = new ByteArrayOutputStream(1024);
try {
   for (int i = 0; i < Model.size(); i++){
      IModel_Pdf_FileElement Element =
									Model.getModel_Pdf_FileElementAt(i);
	baos.write(Element.getLine().getBytes());
   }
    IWDResource resource =WDResourceFactory.createCachedResource(
		baos.toByteArray(),
		"Test",
		WDWebResourceType.PDF);
    pdf.setBinaryResource(resource);

Thanks

Hi Praveen,

Can you try this code sample...to get the Byte Array o/p

IContent content = resource.getContent();

InputStream in = content.getInputStream();

ByteArrayOutputStream out = new ByteArrayOutputStream();

int length;

byte[] part = new byte[10 * 1024];

while ((length = in.read(part)) != -1)

{

out.write(part,0,length);

}

in.close();

My application is working fine with this.

Hope it helps,

Sattam

Thanks for the sample. I use version NWDS7.0 and I don't find IContent type in my NWDS after re-organizing import statements.

currently I use below code to get the PDF on click of LinkToaction UI element (After I set the pdf from backend above part of the code).

{code

IWDResource pdfResource = wdContext.nodePDF().currentPDFElement().getBinaryResource();

String pdfURL = pdfResource.getUrl(WDFileDownloadBehaviour.OPEN_INPLACE.ordinal());

IWDWindow window =

wdComponentAPI.getWindowManager()

.createNonModalExternalWindow(pdfURL , "Test");

window.show();

{code}

Currently above code giving %pdf" error when clicking LTU UI elemnt.

Please suggest How I need to adjust your sample in my case.

Thanks

Hi Praveen,

Sorry for late reply.

Actually it was my fault.... you need to add a few jars, i forgot to mention them in my previous posts. Following is the list

-webdynpro_services.jar

bc.rf.framework_api.jar

bc.sf.framework_api.jar

bc.util.public_api.jar

com.sap.security..api.ep5.jar

com.sap.security..api.jar

prtapi.jar

ps- actually my application involved uploading and downloading from km. So i am not sure which ones are really needed, I gave you all.

Even if this does not work try adding the referance PORTAL:sap.com/com.sap.km.application under Sharing references under web dynpro references.

Pls let me kno in case u face any issues.

Regards,

Sattam

Thanks Sattam.

Could you please paste your sample code on how you set the resource initially from ABAP FM returned String , to create a resource.

I don't see how you get the URL to the resource before you download it.

Thanks

Hi Praveen,

In my application the file is being downloaded from a KM folder, not a FM.

I just provided the part of code where i obtained the output byte array from the resource.

I already knew the path to the resource in KM folder hirearchy.

Regards,

Sattam
