Hi ,

The thread talks completely about a different scenario.I want to get the PDF from a BAPI that returns a SAP SCRIPT form.

Hi jhansi,

Thanks for the reply .But iam talking about getting the smartform in webdynpro using a BAPI.

Hi ,

Insert IFrame UI Element and bind the Resource property to the value attribute PdfUrl of type String .

Define a Output parameter of type Binary in RFC .

Insert the following code to dispaly the smart form

byte[] pdfContent = wdContext.currentOutput<node>().get<Binary>();

IWDCachedWebResource pdfResource = WDWebResource.getWebResource(pdfContent,WDWebResourceType.PDF);

try

{

wdContext.currentContextElement().setPdfUrl(pdfResource.getURL());

}

catch(Exception e)

{

wdComponentAPI.getMessageManager().reportException(e.getMessage(),true);

}

Hi sunitha,

Is this the same process for a smart form or a sap script form.How easy or hard is it in abap to return a binary parameter for the form because mine is a sap script form.

Hi Swathi ,

I am not sure about script form , just give it a trial and see if it works.

Swathi,

See [this thread|;. This worked for me and if you are getting PDF form from RFC, this just might work for you too.

Hi vishwas,

Right now the bapi that is displaying the sap script form doesnt have any export parameters.Can you tell me what they need to pass as export parameters to me so that i can follow that code.I know that thye have to send something of format binary.

The thread that I referred to calls for a Byte Array to be returned from R3 side. Function Module CONVERT_OTF can be used for this purpose.

Hi vishwas,

Swathi,

This is the code from the thread I referred above. Please see if it helps you.

String s=null
    for(i=0;wdContext.nodeTLINE();i++)
    wdContext.nodeTINE().moveFirst();
   {
      strTline = wdContext.nodeTLINE().nodeTLine().currentTlineElement();
    //check the element in TLINE should of lenght of 2 if not then fill with space "". loop it like that. 
   strTdline = wdContext.nodeTLINE().nodeTdLine().currentTdLineElement();
   //check the element in TDLINE shud be of 138 characters if not loop it to and fill it with spaces. 
   s= s+strTline+strTdline;
wdContext.nodeTINE().moveNext();
    }
 
//From this string that is been obtained convert it into bytearray using following:
  byte[] byteString = s.getBytes[];

Hi vishwas,

I was tring to use Bytebuffer and the NWDS cannot resolve that API.I tried to add that lib in the project but i couldnt find it.any idea.

[vmadhuvarshi_]

I found Bytebuffer API in following path. You should find it here too. Are you using ClasLocator tool? It is very helpful in such cases. If not, Search for ClassLocator in SDN.

com.sap.lcr.api.util.ByteBuffer

Hope this helps.

My NWDS still could not resolve the ByteBuffer API .I tried to read the PDF and it says File doesnt start with %PDF- after i resolved this issue and tried to open it directly in adober reader it gives me an error that the file is corrupted.

[vmadhuvarshi_]

I had the same problem - "File doesnt start with %PDF-" and this was solved with ByteBuffer API. I'm using JDK 1.4.2_18 and ByteBuffer API is available to me without any specific imports in these 2 locations.

com.sun.corba.se.internal.ior.ByteBuffer

java.nio.ByteBuffer

See if this works for you.

Hi vishwas ,

Thanks for you help.I could finally resolve the problem with a different apporach even without using bytebuffer.I used filedownload api

Here is my code

wdThis.wdGetBenCustController().Execute_PrintEnrollmentForm();

byte[] byteString = wdContext.currentPrintformElement().getPdf_Xstring();

//byte[] byteString = pdfString.getBytes();

String url = null;

// From this string that is been obtained convert it into bytearray using following:

try{

IWDResource wr = WDResourceFactory.createCachedResource(byteString, "PDF-Report", WDWebResourceType.PDF);

IWDWindow w = wdComponentAPI.getWindowManager().createNonModalExternalWindow(wr.getUrl(0), "PDF-Report");

url = wr.getUrl(WDFileDownloadBehaviour.OPEN_INPLACE.ordinal());

w.show();

}

catch (Exception e)

{

wdComponentAPI.getMessageManager().reportException(e.getLocalizedMessage(), false);

}

All is well that ends well !

Congratulations on finding another solution for this common issue.
