RE: Rubber Stamp/saving error
Hi,
Has anyone encountered this error (I'm using psfbox in a vb.net application):
org.apache.pdfbox.exceptions.COSVisitorException: class configured for MessageDigest(provider: SUN)cannot be found.
What does this mean? What can I do to correct it?
Thanks for your help!
Tasha

Hi all,
I'm trying to create a rubber stamp using pdfbox in a vb.net application. Since I'm new at using this tool, I tried programming loading a PDF and then saving as a different name. I'm getting this error:
org.apache.pdfbox.exceptions.COSVisitorException: class configured for MessageDigest(provider: SUN)cannot be found.
Can you point me in the right direction for troubleshooting? Let me know if you need more information.
Thanks!
Tasha

There have to be a bunch of dlls, 2 of them are the bouncycastle dlls:
bcprov*.dll and bcmail*.dll. You have to ensure that both are on your path.
FYI: those dlls are "converted" jars (java libraries), I guess they are
generated using IKVM [1], maybe you are using an unofficial .NET build by
myself [2] ;-)

Although- I now noticed that the dlls are 1.7.0. Does that indicate version 1.7.0?

Hi Andreas,
I am working on a .net program that was started by someone else in our office who is no longer here. I believe it's version 1.7.1.
I am not familiar with bouncycastle dlls- can you give me more information about this?
Thank you,
Tasha

What version of PDFBox are you using?
Did you build the .NET version of your own or do you use a precompiled version from elsewhere?
The exception sounds like an encryption/decryption issue. Are the bouncycastle-DLLs on your path?

Hi Andreas,
I am working on a .net program that was started by someone else in our office who is no longer here. I believe it's version 1.7.1.
