Thanks,

The java example link i provided should have been -
http://svn.apache.org/repos/asf/pdfbox/trunk/examples/src/main/java/org/apache/pdfbox/examples/pdmodel/ExtractEmbeddedFiles.java

But your suggestion WORKS.

Now i am able to extract the attached file located in the *attachments tab*but
*haven't been able to extract the attached file located in page*. I am
getting null efTree in this case.

         PDDocumentNameDictionary namesDictionary = new
PDDocumentNameDictionary(pdfDoc.getDocumentCatalog());
         PDEmbeddedFilesNameTreeNode *efTree *=
namesDictionary.getEmbeddedFiles();

So now working on it.

Embedded files are always document related. If an embedded file is referenced
on a single page a file attachment annotation is used. Try something like this
to get all annotations of a single page:

List annotations = page.getAnnotations();

The one you are looking for has to be an instance of the class

org.apache.pdfbox.pdmodel.interactive.annotation.PDAnnotationFileAttachment.

  Hi,

    I am developing .NET Application using pdfbox to extract metadata,
content and attached file from PDF.

I was able to extract metadata and content, but stuck while extracting
attached/embedded files.

I have a pdf with embedded/attached doc file and want to retrieve that
file. I have gone through the java example -
http://www.docjar.com/html/**api/org/apache/pdfbox/**examples/pdmodel/**
EmbeddedFiles.java.html<http://www.docjar.com/html/api/org/apache/pdfbox/examples/pdmodel/EmbeddedFiles.java.html>
.

But while trying to use it in .Net, i got "non generic type
'java.util.Map'
cannot be used with type arguments" in the following code snippet

java.util.Map<String, COSObjectable> names = efTree.getNames();

So, i will be grateful if anybody help me to extract the file from pdf.

I'm not a .NET expert and don't know what may cause that issue. But maybe
it is
a good idea to just omit the generics and try something like this:

java.util.Map names = efTree.getNames();

  Thanks in advance.
