I'm getting minor variations on the following error
when I try to create a PDDocument in an Applet from a URL.

>> java.security.AccessControlException: access denied
(java.util.PropertyPermission java.io.tmpdir read)

java.security.AccessControlContext.checkPermission(Unknown

-----------------------------------------------------
I've tried:
1) "PDDocument.load( InputStream input)"
2) "PDDocument.load( File file)"
3) "PDDocument.load( String filename)"

All methods give me the AccessControlException, but
with one subtle difference:

A) Using the InputStream method via:

> URL url = new URL(
"http://localhost/Images/btP72.pdf");
> PDDocument doc = "PDDocument.load( url.openStream() );

or:
> byte data[] = new byte[ (new URL(
"http://localhost/Images/btP72.pdf")).openConnection().urlConn.getContentLength()
];
> int dRead = fileLoc.openStream().read( data);
> doc = PDDocument.load( new
ByteArrayInputStream( data) );

I get:

>> java.security.AccessControlException: access denied
>>+ (java.util.PropertyPermission java.io.tmpdir read)

B) Using the File and String methods via:

> File f = new File(
"http://localhost/Images/btP72.pdf");
> PDDocument doc = PDDocument.load( f);

or:
> PDDocument doc = "PDDocument.load(
"http://localhost/Images/btP72.pdf");

I get:
>> java.security.AccessControlException: access denied
>>+ (java.io.FilePermission
http:\localhost\Images\btP72.pdf read)

-----------------------------------------------------

I'm speculating at the moment, but it looks as though
PDFParser is attempting to look at the PDF file as
though it existed on my disk and not from the web.

I'm using
PDFBox version: PDFBox-0.7.2
Windows XP SP2

I found that I can bypass this problem by placing my code in
a JAR file and signing it (I also signed the PDFBox.jar
file, although I'm not sure that is necessary).

Even with this bypass, I think it would be better if I
didn't need to sign the code. I also feel that printing PDF
files is important enough for web applications, that it
would be worth while to create a subset of PDFBox that only
creates images for printing. This should have two advantages:
1) Smaller JAR files will be travelling around the web.
2) There should be no need to create temporary disk files.
