Generating PDF in Web-Dynpro

Hello,
I have a problem with generating a PDF file with ABAP WebDynpro. I have an ALV and there I read a line. From this line I want to build a smartform which should be converted into PDF. I think my coding works. I have no syntax errors and when I debug the coding, everything looks good. I also get my popup that I want to have. But then I got an error: "File does not begin with '%PDF-'."
I look for this error here in SDN but I could not find a solution. I have also tried to do what is mentioned in note 1042424.
Can anybody helps me?
Regards, Markus

Dynamically generate PDF with web dynpro

Is it possible to generate a PDF in web dynpro abap without using the interactive form UI element ? In other words just take the data in my context and convert that into a xstring pdf using a predefined template and interface?

Prerequisites to generate PDF in web dynpro

hi Web dynpro Gurus,
I am trying to create a web dynpro application, which uses two BAPIs, The first BAPI output results in some data which I am displaying in a table format.
Now among the data retrieved from the first BAPI is INVOICE number.
Now on clicking the invoice number, the second BAPI should be called and that would result in the PDF file.
So please help me in this issue.
Thanks and regards

Generating PDF in Web-Dynpro   - empty window popup

Hi Expertise,
   I notice that in FM Y_GLXX_WD_JAVA_PDF has calls CONVERT_OTF. It returns different value bin_file in 4.6 & ecc6. In Ecc6 there wasnt return PDF header %PDF 1.3 - ......... but 4.6 had returns. It cause the portal site will prompt out empty windows instead of prompt out PDF screen.
Any ideas, which FM should i use to replace CONVERT_OTF or other solutions??

For your information, i am currrently developing in Webdynpro Java. But, i don't think that is the case because the Java code will convert the Binary String to Bytes. The problem is why the BAPI returning different BIN_FILE values from two different system (ECC6.0 & 4.6C)?
After the execution, the BAPI will return the PDF value as String
[http://inakimi.multiply.com/photos/album/48/webdynpro#1]
And this is the code in WD Java converting the String to Bytes:
     IWDCachedWebResource resource;
     wdThis.setData();
     String line = wdContext.currentOutputElement().getBin_File();     byte[] pdfContent = line.getBytes();
     try{
          resource = WDWebResource.getWebResource(pdfContent,   WDWebResourceType.PDF);
          IWDWindow window = wdComponentAPI.getWindowManager().createNonModalExternalWindow(resource.getURL(), "PDF File");
          window.setWindowPosition(5, 5);
          window.setWindowSize(600, 600);
          window.show();
     }catch(Exception e){

How to display smartform as PDF in web dynpro java

Hi,
Where can I find sample program to display smartform as PDF in web dynpro java.
Thanks.
Regards,
Henry

1. Create a smart form in the R/3 side
2. Now create a function module with the corresponding export parameter:
3. Make sure that the function module is marked remote enabled.
4. In NWDS create an Adaptive RFC model which points to the FM created in R/3 under the webdynpro application
5. Now create an application and view inside it to display the PDF and Insert a frame inside the view
6. Create a value node and an attribute say url of type string inside that node and bind it to the source
7. In the doInit() method place the following code
>    ZTest_Pdf_1_Input input = new ZTest_Pdf_Input();
>    wdContext.nodeZTest_Pdf_Input().bind(input);
>    try {
>            wdContext.currentZTest_Pdf_InputElement().modelObject().execute();
>            }
> catch (Exception e) {
>                        e.printStackTrace();
>            }
> wdContext.currentInternalElement().setUrl(convert(wdContext.currentOutputElement().getBin_File()));
Inside that view create a method to convert the string to url so that it can be passed as a string to the setUrl method of the currentContextElement() , say convet(byte[] doc_content) which return a string.
Inside that methos write the following code,
>         String url = "";
>           WDWebResourceType webResType = WDWebResourceType.PDF;
>            IWDWebResource webResource = WDWebResource.getWebResource(doc_content, webResType);
>            try {
>                        url = webResource.getURL();
>            }
> catch (Exception e) {
>                        e.printStackTrace();
>            }
>            return url;
Hope It will be helpful

Generate Adobe Interactiveform pdf using Web Dynpro Java API.

I created pdf form by using standard "InteractiveFormElement" and it is displaying correctly in browser.
Now there is a requirement to provide url link to the same pdf that is displayed with InteractiveFormElement. To generate pdf, I was doing something the below.
//Copied XDP file from the srcconfigurationcomponents<package><file>.xdp
//to srcmimiescomponents<package><file>.xdp
try {
 templateUrl = WDURLGenerator.getWebResourceURL(
 wdComponentAPI.getDeployableObjectPart(),
 "CompView_InteractiveForm.xdp");
} catch (WDURLException e) {
IWDPDFDocumentCreationContext pdfContext =
 WDPDFDocumentFactory.getDocumentHandler().getDocumentCreationContext();
pdfContext.setData(
 WDInteractiveFormHelper.getContextDataAsStream(wdContext.nodeDataNode()));
pdfContext.setTemplate(templateUrl);
IWDPDFDocument pdf = null;
try {
 pdf = pdfContext.execute();
} catch (WDPDFDocumentRenderException e) {
 wdComponentAPI.getMessageManager().reportException(
"pdfContext.execute() " + e.getLocalizedMessage(), false);
IWDPDFDocument.execute() is raising exeception "Template used in PDF render
operation is invalid or cannot be found". template url is indeed correct. I checked by
assigning to that url to linkToUrl Element and opening the xdp file.
Please help me to identify the issue. Thank you.

Hi Ajay,
Use getResourcePath instead of getWebResourceURL
templateUrl = WDURLGenerator.getResourcePath(
 wdComponentAPI.getDeployableObjectPart(),
 "CompView_InteractiveForm.xdp");
Thanks
Ram

Print a PDF from Web Dynpro

Hi all gurus.
I developed a Web Dynpro application to let the users create their own sales orders.
Now I need to let them print the orders when they need to. Searching on the documentation I have, I've never found anything about crating a pdf print from the WD Application.
There must be a way, because I managed to do that even with the very old ITS (the one in which you had to write HTML code...) but i cannot find how.
Can anyone help me please? Even a tutorial would be very appreciated.
Thank you in advance...

You need a Smartform, SAPScript, or AdobeForm to be defined for your output. Define an action/method for print, then pass the data to your Form. SmartForms are not bad, as SmartForms generate a Function Module, and are easy to call.
Call the SmartForm Function with PDF output = 'X' (parameter within Output Control I think). Then pass the PDF_DATA[] table (type = TAB_SOLIX) to a new window output .
Don't have the code in front of me, but have done it several times.
Adobe Forms is another good option, but you need Adobe Server, and generally I have found ADOBE to be SLOOOOOWWWWW. I think Steve Jobs might have been on to something with ADOBE -- just my opinion.
And of course, it can be done with SAPSCript, but I would need a whole blog on how to do that.....

Mass upload & Download of PDFs in Web Dynpro ABAP

Hi All,
Is it possible to download multiple PDF's at one go ? for example if you have a Table UI control where each row has one clickable link that generates a PDF using WebDynpro ABAP Application, we want to enable multiselect property of Table UI and provide Mass Download Button control on click of which all selected rows should generate PDF and then get dowloaded to a specific location on machine (c:/). or if there is any other alternative possible ?similarly for Mass Upload we wish to multi select PDFs and upload them to R/3 at one go ?
please let me know if such thing is possible ? if yes is it a good option to have ? as we have users who have to upload these PDF one by one and they wish if they could simply select all PDFs at one go and click Mass upload..Note that there are some validation that we perform once we upload PDF before posting PDF data to backend.
your help & comments would be Highly Appreciated !!
Thanks

You simply use the CL_ABAP_ZIP class to combine the multiple binary strings of the word files together.
data izip type ref to cl_abap_zip.
data zip_xstring type xstring.
create object izip.
loop at ifiles assigning <Wa_file>.
izip->add( name = <wa_file>-filename
content = <wa_file>-filecontent ).
endloop.

The connection test in SM59 only does a basic PING to the web service endpoint. Often it will show OK, when in fact the ADS is not setup correctly. That is why there are some test applications that do more.
For proper testing of your setup see OSS Note 944221. But basically run the ABAP programs FP_PDF_TEST_00 and FP_CHECK_DESTINATION_SERVICE. You can also try running the web dynpro components WDR_TEST_ADOBE and WDR_TEST_ADOBE_PDF_ONLY

Smartform as PDF in Web Dynpro for ABAP

Hello Experts,
I have developed one Web Dynpro application in which i am trying to show PDF converting from smart from on button click.
I am seeing blank screen when i try to display PDF? But when i check i debugging data passed successfully to context element.
PDF source property mapped to review context element.
I used below code to show PDF in view method:
call function 'SSF_FUNCTION_MODULE_NAME'
call function lv_fm_name
call function 'SSFCOMP_PDF_PREVIEW'
call function 'CONVERT_OTF'
elem_pdf->set_attribute(
   exporting
         name = `SOURCE`
          value = data ).
Thanks
Rajesh Yadla

Looks quite alright, but since you only have provided a few function modules, there is 'no' way of telling what is going wrong. I can however give you a link and compare your coding with the one from the tutorial:

After SP upgrade, pdf in web dynpro could not display dollar symbol

Dear Experts,
      We have updated the following support packages:
     SAP_BASIS 14-18
     SAP_ABA 14-18
     PI_BASIS 14-18
     SAP_BW 15-20
     SAP_AP 12-15
     EA-HR 23-61
     SAP-HR 23-61
     E-RECRUITMENT 18
     After that, Some webdynpro for abap which used PDF report has some errors, which dollar could not be displayed, which indicates some kind of error 'o'.
     We check that the pattern is of this column is from old version :num{$zzz,zzz,zz9.99} to num{($z,zzz,zz9.99)} . How could we deal with this ? And where could I find the related influence of the SP upgrade of adobe and web dynpro?
Thanks & Best Regards,

Display archive doc as pdf from web dynpro?

Hi All,
We have a situation where we want to display archived pdf's from a web dynpro. I have put an interactive form ui element on my view and bound this to an attribute of type xstring on the context.
When I run it, i get an error message saying that file does not begin with '%PDF-'. I've tried putting this on the front of the string but i didn't work either.
So can anyone tell me the process for displaying archived pdf's from a web dynpro.
Many thanks in advance,
Liz.

This is the code necessary to get it to work:
get optical archive id of pdf to display
    select single * from toahr into ls_toahr
      where sap_object = 'PREL'
        and OBJECT_ID = lv_obj_id

       others                         = 4.
    if lt_archivobject[] is not initial.
      describe table lt_archivobject lines lv_rowcount.
      lv_rowcount = lv_rowcount * 1024.

Generating a PDF in Web Dynpro without using InteractiveForms

Hello All,
I have been following this tutorial <a href="http://sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/webdynpro/tutorial%20on%20working%20with%20the%20pdf%20document%20object%20-%2032.htm">http://sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/webdynpro/tutorial%20on%20working%20with%20the%20pdf%20document%20object%20-%2032.htm</a> from SDN and is currently stuck.
What I'll like to achieve
1) User logs on to the system and a table displaying a list of items for approval appears.
2) the user is then able to select a row item from the table and click on 'approve'. In doing so, my application should generate a pdf form in the background and attach it as an email attachment and sent that email to an appointed vendor.
Problem
As there is no InteractiveForm involved, I do believe I will need to provide the template (.xdp) so that the PDF can be generated. In the tutorial, it suggests doing this (I modified it a little to reflect my own path name):
InputStream templateSourceInputStream = getClass().getClassLoader().getResourceAsStream("d:
usr
sap
pdf
PDF
XBCRPDFPreviewView_InteractiveForm1.xdp");
However, I am given a NullPointerException when I attempt to do that. Does anyone has any idea what may have caused the error ? Thank you.

Hi Kwok Wei ,
According to the convention the any file can be placed in the src/mimes/Components/<component package + component name>/folder of your webdynpro project along with other generated files of your application.
After this you just need to pass the filename to the getResourcestream() method,it automatically picks up the file from the folder.
