Re: PDFBox under partial trust

[James Montagne IV <ki...@gmail.com>]

It is not specific to a newer version of windows.  In fact my environment is
server 2003.  The group who will be hosting the code wants our application
to run under Medium trust which basically restricts which resources the code
has access to.  "Partial Trust" means anything that isn't Full trust.

After some reading, it appears that the newer versions of IKVM have added
experimental support for partial trust.  So rebuilding the pdfbox DLL using
the newer version of IKVM may solve my problem.  Before I dive into that, I
was wondering if there was any guidance online about building the pdfbox
dll.  So far I just found something on the site saying it was best not to
try and build your own.  Any information anyone could provide would be
extremely useful.

Re: PDFBox under partial trust

[James <ki...@gmail.com>]

It was with the latest version of IKVM, but I actually wound up building it
all piece by piece using ikvmc.  It was tedious but worked eventually.

I haven't managed to completely narrow it down yet.  I know it happens when
I call PDDocument.load and from the stack trace I can see it happens in
org.apache.pdfbox.pdfparser.PDFParser.  But the exception doesn't actually
tell which assembly it is trying to use that is causing the issue.

Re: PDFBox under partial trust

[Daniel Wilson <wi...@gmail.com>]

I saw on the IKVM thread that you had indeed done the IKVM build of PDFBox.

Is that using the very latest IKVM?  If so, would you be willing to share
the changes to the build script?

As far as the partial trust goes, does anything give you any indication what
it is that's preventing it?  Some particular Java library in use perhaps?

Thanks

Daniel

Re: PDFBox under partial trust

I built the DLL set using IKVM and placed it at the URL above.  As noted
there, I simply did an ant Build.NET ... after setting up my .snk file and
telling the build script where to find it.

Setting up the IKVM stuff is not as hard as it sounds.
