How do I get all the attachments from a .nsf(lotus notes) file using java

Solution 1
No need to use evaluate
, look up the extractFile
in the Lotus Designer Help
From the Lotus help:
import lotus.domino.*;
import java.util.Vector;
import java.util.Enumeration;
public class JavaAgent extends AgentBase {
public void NotesMain() {
try {
Session session = getSession();
AgentContext agentContext = session.getAgentContext();
// (Your code goes here)
Database db = agentContext.getCurrentDatabase();
DocumentCollection dc = db.getAllDocuments();
Document doc = dc.getFirstDocument();
boolean saveFlag = false;
while (doc != null) {
RichTextItem body =
(RichTextItem)doc.getFirstItem("Body");
System.out.println(doc.getItemValueString("Subject"));
Vector v = body.getEmbeddedObjects();
Enumeration e = v.elements();
while (e.hasMoreElements()) {
EmbeddedObject eo = (EmbeddedObject)e.nextElement();
if (eo.getType() == EmbeddedObject.EMBED_ATTACHMENT) {
eo.extractFile("c:\\extracts\\" + eo.getSource());
eo.remove();
saveFlag = true;
}
}
if (saveFlag) {
doc.save(true, true);
saveFlag = false;
}
doc = dc.getNextDocument();
}
} catch(NotesException e) {
System.out.println(e.id + " " + e.text);
e.printStackTrace();
}
}
}

You need to get the attachments out of each document, as opposed to the EmbeddedObjects. Something like this:
import java.util.Iterator;
import lotus.domino.*;
public final class DocAttachmentParser implements Iterator {
private Session s;
private Document doc;
private Double count ;
private Iterator attIterator = null;
public Double getCount() {
return count;
}
public DocAttachmentParser(Session s, Document doc) throws NotesException {
this.s = s;
this.doc = doc;
if (s!=null && doc !=null){
this.count = (Double) s.evaluate("@Attachments", doc).elementAt(0);
if (count.intValue() > 0){
attIterator = s.evaluate("@AttachmentNames", doc).iterator();
}
}
}
public boolean hasNext() {
return count.intValue() > 0 ? attIterator.hasNext(): false;
}
public Object next() {
return count.intValue() > 0 ? attIterator.next(): null;
}
private String nextAttName(){
return count.intValue() > 0 ? attIterator.next().toString(): null;
}
public void remove() {
if (count.intValue() > 0) attIterator.remove();
}
public String getAll(){
StringBuilder sb = new StringBuilder();
if (count.intValue()>0){
while (hasNext()) {
sb.append(nextAttName());
}
}
return sb.toString();
}
}

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<Item> allItems;
allItems = doc.getItems();
HashSet<String> attNames = new HashSet<String>();
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<String> atts = new HashSet<String>();
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;
}

Steps followed :
Took a back of my lotus notes as sample.nsf
And then tried to read the attachments from the sample.nsf
Code snippet :
Database db = session.getDatabase("","C:\\Projects\\NotesToJava\\sample.nsf"); DocumentCollection dc = db.getAllDocuments(); Document doc = dc.getFirstDocument(); while (doc != null) { RichTextItem body = (RichTextItem) doc.getFirstItem("Body"); if (body.getEmbeddedObject("Request.xlsx") != null) System.out.println("Found BPM_Dev_Access_Request.xlsx in " + doc.getItemValueString("Subject")); doc = dc.getNextDocument(); }
