To get all attachment from a notes document then i wrote this method(part of my class). This method takes the document and extract the attachment(Rich Text field)from Notes Document. This class also help you to know consider Example: In two document if there is same Attachment it extracts only one.

Here just you have to set "filePath" where you have to extract your attachment.

public boolean export(Document doc ) throws NotesException { 

if (doc.hasEmbedded()) {
        Vector allItems;
        allItems = doc.getItems();
        HashSet attNames = new HashSet();

        for (int i = 0; i < allItems.size(); i++) {
            Item item = allItems.get(i);
            if (item.getType() == Item.RICHTEXT) {
                RichTextItem riItem = (RichTextItem) item;
                Vector emb = riItem.getEmbeddedObjects();
                String[] doublette = new String[emb.size()];
                Set atts = new HashSet();
                for (int j = 0; j < emb.size(); j++) {
                    EmbeddedObject embObj = (EmbeddedObject) emb.get(j);
                    if (!attNames.contains(embObj.getName())) {
                        attNames.add(embObj.getName());
                        StringBuffer test = new StringBuffer(
                                embObj.getSource());
                        test.append('-');
                        test.append(embObj.getName());
                        test.append('-');
                        test.append(embObj.getFileSize());
                        String attDesc = test.toString();
                        if (atts.contains(attDesc)) {
                            doublette[j] = attDesc;
                        } else {
                            doublette[j] = "";
                            atts.add(attDesc);
                        }

                    } 

                }

                for (int j = 0; j < emb.size(); j++) {
                    try {
                        EmbeddedObject embObj = (EmbeddedObject) emb.get(j);
                        String itemName = riItem.getName();
                        bOk = extractFile(embObj, itemName);
                        embObj.recycle();
                    } catch (NotesException e) {
                        bOk = false;
                        if (!"".equals(doublette[j])) {
                            bOk = true;
                            System.out.println(" duplicated attachment:")
                            log.append(doublette[j]);

                        }
                    }
                }
            }
        }



    }
   return bOk;
}

  private boolean extractFile(EmbeddedObject embObj, String itemName)
        throws NotesException {
    boolean bOk = true;
    if (embObj.getType() == EmbeddedObject.EMBED_ATTACHMENT) {

            String fileName = embObj.getName();      
                    String filePath = this.filesPath + fileName;
                    // Check if file already exists, then delete
                if (FileUtils.killFile(filePath, false, true, true)) {
                        embObj.extractFile(filePath);
                    } else {
                        bOk = false;
                        System.out.println(", error in kill: " + filePath);
                    }           
    }
    return bOk;
