In PDF file there are at least two ways to specify a link to external files:
The first one is this (as it turns out, Acrobat Reader has problem launching
the document)
127 0 obj<</Border[0 0 0]/Rect[669.16 447.6 729.14 457.6]/Subtype/Link/C[0 0
1]/A<</S/Launch/Win<</D(.\\docs)/F(dm.xpt)/O(open)>>>>>>
endobj
This can be done with PdfAction action=new PdfAction("dm.xpt", null, "open",
".\\docs");
The other one is the following - do we have a PdfAction that create the content
like this? If no, what do I need to do to create a PdfAction myself (I am in a
hurry to get the job done, no time to go throught the iText source code). It
seems that Acrobat Reader works well with this style.
1246 0 obj
<<
/S /Launch
/F 1247 0 R
>>
endobj
1247 0 obj
<<
/Type /Filespec
/F (ae.xpt)
>>

OK, more information I found out - when clicking the link, sometimes Acrobat
launches the external application with the full absolute path to the external
file (i.e., it combines the information from the D word and F word, and
translates the '.' to the parent Dir of the PDF file, this is Acrobat 7.0.0),
but sometimes it only provides the path that is defined in the F word (this is
in 7.0.8)
I am not sure if this is related to the viewer preferences, or the Acrobat
configuration.
Can anyone shed light how to deal with this issue?

I need to link a PDF file with some external non PDF files. The external files
are saved in a location that is fixed relative to the PDF file - if the PDF
file is saved in c:\pdf, then the external files must be saved under
c:\pdf\docs. I need to use relative path to reference these files.
Here is the code I used to set up the link:
chunk=new Chunk(text, link_font);
PdfAction action=new PdfAction("dm.xpt", null, "open", ".\\docs");
chunk.setAction(action);
and here is the link in the PDF file
127 0 obj<</Border[0 0 0]/Rect[669.16 447.6 729.14 457.6]/Subtype/Link/C[0 0
1]/A<</S/Launch/Win<</D(.\\docs)/F(dm.xpt)/O(open)>>>>>>
endobj
But the link does not work SOMETIMES. When click on the link, sometimes it can
find the file, but sometimes it cant't (I verified that the file is there). I
use Acrobat 7.0 to view the PDF files. It works if viewed in Windows XP
(personal computer), but doesnt work in Windows 2000 (corporate network).
I am using iText version: 2.1.3, JRE 5.0
Any thought would be appreciated.
