updating data in adobe form

[Former Member]

Hi All,

In my java webdynpro application, i want to show an adobe form and allow the user to update the data. Then, i want to store the form in binary in a db table.

The layout of my form is not fixed as a different form can be uploaded each time. So, all i have is the binary of the interactive form.

I have added the interactive form uielement in my view. I have bound the 'pdfsource' property to a context attribute that contains the binary of the interactive form to be shown. Also, i have chosen 'usepdf' in the mode.

Now, after the user updates the form, if i read the context attribute bound to pdfsource, will i get the updated data in the form? Or should i do anything more to get the desired result?

Thanks and Regards,

Ram

Hi Ram,

In my Project we solved the same type of situation in following Procedure.

1.) First after the User enters data in to the Form u hav to read it from the PDF

by using this code .It converts the Data in to XML Format.

public String getData(String pdfSource) throws EJBException

{

ByteArrayOutputStream pdfSourceOutputStream = new ByteArrayOutputStream();

try

{

InputStream pdfSourceInputStream = new FileInputStream(new File(pdfSource));

IOUtil.write(pdfSourceInputStream, pdfSourceOutputStream);

pdfSourceInputStream.close();

}

catch (Exception e)

{

System.out.println(e.getMessage());

throw new EJBException(e.getMessage());

}

IWDPDFObject pdfObject = WDPDFObjectFactory.getPDFObject();

pdfObject.setPDF(pdfSourceOutputStream);

ByteArrayInputStream dataInputStream = (ByteArrayInputStream) pdfObject.getData();

if (dataInputStream == null)

{

return(null);

}

else

{

try

{

String output = formatData((InputStream) dataInputStream);

return(output);

}

catch (Exception e)

{

System.out.println(e.getMessage());

throw new EJBException(e.getMessage());

}

}

}

2.) Then u can get the data from tht XML code easily & store it in the Data Base where u need.

--> For more Details watch the " TutWD_PdfObject " Sample Application from this site .

I Think It helps u lot.
