Hi everybody,

I've got an unknow error when I run my RapidMiner process on some folder.
To make a long story short, the goal of my process can be describe as following:
 Starting points:
  • Excel file .xls with "Open File"
  • the path of a directory to scan with "Set macro"
Outputs of the process
  • a PDF report
  • several ExampleSet
The process counts words, keywords, calculates ratios ...
It works very well on some folders and on others I've got the following pop-up message:

Process failed
org/bouncycastle/jce/provider/BouncyCastleProvider
Reason: org.bouncycastle.jce.provider.BouncyCastleProvider
The process works on HTML and PDF files but in all folder there are also xls, csv, doc.

Can somebody help me please?
Thanks in advance
Johan

P.S.: I can't put the process because it's too long.

    Hi Everybody,

    I've got some new information about my problem.
    The error occurs when I try to analyze PDF which is "protected".

    Can somebody help me to solve this problem?

    Thanks in advance
    Johan

    Hi,

    unfortunately protected PDFs are currently not supported by the Text Extension, so you will have to make sure there are no protected PDFs in a folder you're trying to process.
    Thank you for reporting it however, I created an internal ticket for this issue.

    Regards,
    Marco

    Hi Marco,

    Thank you for your reply.
    I found a small freeware to convert PDFs to Text and runs on protected also.
    http://www.colorpilot.com/extract-pdf-text.html
    Moreover this software is open source, maybe it can be usefull for a futur release of Text Processing Extension  ;)

    Regards,
    Johan
