How to validate if a document holds required text-anchor?

Thursday, January 5, 2017 at 11:27pm

Hello Team, I have the following scenario: I am trying to create a Package with a PDF document, which is provided as binary stream. I also want to add a Signer(s) Signature(s) and to locate these through corresponding text-anchors. In case when the required text-anchors are not available in th ePDF document I get the following Error:

com.silanis.esl.sdk.internal.EslServerException: Could not upload document to package. 

Exception: HTTP POST on URI https://sandbox.esignlive.com/packages/qYSDX1Frsvn5-T-F8Hg39g5fWm4=/documents 
resulted in response with status code: [400, Bad Request]. 

Optional details: 
{
	"messageKey":"error.validation.verifyDocument.couldNotBeFlattened",
	"message":"Could not upload PDF document: it contains a syntax error preventing proper processing of its data.",
	"code":400,
	"name":"Validation Error"
}

which then results in my Package created and in DRAFT State and this outcome is not required. My question is: Is there a functionality in the SDK where I could validate if the required text-anchor is present in the provided PDF binary stream, before I send the EslClient - "Create&Send" call? Thank you very much.

Hi, Unfortunately, there is no way to pre-validate if a text is present using the Java SDK. You will have to use an external library to search through your PDF to make the check. Here's one example using PdfBox and Apache Lucene: http://hello-world-2-0.blogspot.ca/2008/03/java-library-to-search-in-pdf-files_12.html

Hello Haris, Thank you very much fore the update. I think it would be handy if we could have some sort of PackageDocument pre-validation before we call eslClient Create Package. For example:

try {
   eslClient.validatePackageDocument();
} catch (EslException e) {
   //ECHO there was problem with Package set up!!!
   System.out.println(e.getMessage());
}

In the mean time I will check the provided URL . Regards, Kosta.

Hello Haris, could you please check the raised enhancement suggestion that I did (link in my previous post) and check if this has been checked or not? It's being more than a week since I created it and there were no comments on this. Thank you in advance. Kosta.
