Hi,

I have got a requirement that corrupted PDF files shall not be able to be uploaded.

I saved pyUploadFile to our framework and created a Java step using this PreflightParser Java code I found:

org.apache.pdfbox.preflight.parser.ValidationResult result = null;

org.apache.pdfbox.preflight.parser.PreflightParser parser = new org.apache.pdfbox.preflight.parser.PreflightParser(fileLinkedRefTo);
try
{

    
    parser.parse();

   
    org.apache.pdfbox.preflight.parser.PreflightDocument document = parser.getPreflightDocument();
    document.validate();

    // Get validation result
    result = document.getResult();
    document.close();

}
catch (org.apache.pdfbox.preflight.parser.SyntaxValidationException e)
{
   
    result = e.getResult();
}

// display validation result
if (result.isValid())
{
    System.out.println("The file " + fileLinkedRefTo + " is a valid PDF/A-1b file");
}
else
{
    System.out.println("The file" + fileLinkedRefTo + " is not valid, error(s) :");
    for (org.apache.pdfbox.preflight.parser.ValidationError error : result.getErrorsList())
    {
        System.out.println(error.getErrorCode() + " : " + error.getDetails());
    }
}

 

 This unfortunately does not work and I always receive error messages that the used classes cannot beresolved to a type, although I added the all the paths. Can anybody help me with a better (and working) solution for this? Thank you so much in advance!
