app freeze on pdmodel.PDDocument.openProtection

[CDB <cb...@burkeitconsulting.com>]

Hello 

I have an application using POI to open many pdf documents and it appears to
freeze on some of them.
At first I thought it was password protection but it doesn't happen only to
password protected pdf's

The error is included in the attached.

Exception in thread "Consumer-2" java .lang.NoClassDefFoundErrro:
org/bouncycastle/jce/provider/BouncyCastleProvider
At org.pdfbox.pdmodel.PDDocument.openProtection(PDDocument.java:905)

I am looking at the code to catch the exception but I am puzzled why it
locks at runtime and not propagate error and terminate application

Thanks


Charles

I guess this is a typo. POI [1] is a java based library to work with ms office
documents. You're talking about PDFBox aren't you? ;-)

Sounds like a missing jar. You should use the precompiled jar [2] including
everything which is needed or you should simply add the boucy castle
jars as listed here [3].
