How can I access my gmail emails from a Java application? - java

I want to fetch the emails of my gmail account from Java code. How can I go about doing this?

Here is the Refresh Working Code, that Displays the Email msgs in the console in a proper format along with the Attachments also being Downloaded....

Another option: if you don't mind it being a Gmail-specific solution, note that Gmail also provides an RSS feed to your mailbox, which you can then access with normal XML processing APIs.

Gmail uses IMAP, which Javamail can use. Try to use that in an implementation, and if you get stuck, post some more specific questions here.

Here is the code which fetch mail along with it's attachments (if any) from a gmail account using POST OFFICE PROTOCOL (pop3) .

reading text (user:pass) from txt file character by character

Im trying to read username and password from .txt file in Java.
Format of file is as following:
user1:pass1
user2:pass2
user3:pass3
My code can't properly read passwords, any hints?
EDIT: also missing last password because last \n is missing, any way to repair it instead of adding extra newline to txt file?
try {
FileReader fileReader = new FileReader(filename);
BufferedReader bufferedReader = new BufferedReader(fileReader);
int c;
String user = "";
String pass = "";
char helper = 0;
while(( c = bufferedReader.read()) != -1 ) {
System.out.println((char)c);
if((char)c == '\n') {
ftpServer.addUser(user, pass);
//System.out.printf("%s", pass);
user = "";
pass = "";
helper = 0;
} else {
if ((char) c == ':') {
helper = ':';
}
if (helper == 0) {
user += (char) c;
}
if (helper == ':') {
if ((char) c != ':')
pass += (char) c;
}
}
}
bufferedReader.close();
}

If using JAVA: 8 and 8+ you could use stream on Files - java.nio.files
Path path = Paths.get(filename);
try (Stream<String> lines = Files.lines(path)) {
lines.forEach(s -> {
if (s.contains(":")) {
String[] line = s.split(":");
String userName = line[0];
String pass = line[1];
System.out.println("User name: " + userName + " password: " + pass);
}
});
} catch (IOException ex) {
// do something or re-throw...
}
Or use BufferedReader
BufferedReader reader;
try {
reader = new BufferedReader(new FileReader("/Users/kants/test.txt"));
String lineInFile = reader.readLine();
while (lineInFile != null) {
if (lineInFile.contains(":")) {
String[] line = lineInFile.split(":");
String userName = line[0];
String pass = line[1];
System.out.println("User name: " + userName + " password: " + pass);
}
lineInFile = reader.readLine();
}
reader.close();
} catch (IOException e) {
e.printStackTrace();
}
}
NOTE: You must add further null checks and try-catch handlings. Above code is just to show you the logic.

I dont think you need an additional loop
public static void main(String[] args) throws IOException {
BufferedReader reader;
try {
reader = new BufferedReader(new FileReader(
"path/to/file"));
String line = reader.readLine();
while (line != null) {
System.out.println(line);
// read next line
line = reader.readLine();
if (line.contains(":")) {
String user = line.split(":")[0];
String pass = line.split(":")[1];
System.out.println("User is " + user + "Password is " + pass);
} }
reader.close();
} catch (IOException e) {
e.printStackTrace();
}
}
prints
user1:pass1
User is user2Password is pass2
user2:pass2
User is user3Password is pass3
user3:pass3

Here is an elaborated implementation -
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;
import java.util.HashSet;
import java.util.Set;
import java.util.stream.Stream;
public class ReadFileAsStream {
public static void main(String... arguments) {
CredentialsParser parser;
try {
parser = new CredentialsParser("c:/temp/credtest.txt");
Credential[] credentials = parser.getCredentials();
for (Credential credential : credentials) {
System.out.println(String.format("%s : %s", credential.getUsername(), credential.getPassword()));
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
//Parser for the credentials file format
class CredentialsParser {
private Set<Credential> credentials = new HashSet<>();
String filename = null;
public CredentialsParser() {
super();
}
public CredentialsParser(String filename) throws IOException {
super();
setFilename(filename);
if (getFilename() != null) {
parseCredentialsFile();
}
}
public Credential[] getCredentials() {
return credentials.toArray(new Credential[credentials.size()]);
}
// method to add credentials
public void addCredential(String entry) {
if (entry.indexOf(':') > -1) {
String[] values = entry.split(":");
credentials.add(new Credential(values[0], values[1]));
}
}
public String getFilename() {
return filename;
}
public void setFilename(String filename) {
this.filename = filename;
}
protected void parseCredentialsFile() throws IOException {
// read file into stream, try-with-resources
try (Stream<String> stream = Files.lines(Paths.get(filename))) {
stream.forEach(this::addCredential);
}
}
}
// Value holder for each credential entry
class Credential {
private String username = null;
private String password = null;
public Credential() {
super();
}
public Credential(String username, String password) {
super();
this.username = username;
this.password = password;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}

Please modify your code to this :
Use split method to make your work easy :)
public class Example {
public static void main(String[] args) {
BufferedReader reader;
try {
reader = new BufferedReader(new FileReader("F://test.txt"));
String line = reader.readLine();
while (line != null) {
String[] lineParts = line.split(":");
System.out.println("user : " + lineParts[0]);
System.out.println("password : " + lineParts[1]);
line = reader.readLine();
}
reader.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
In test.txt :
user1:pass1
user2:pass2
user3:pass3
Output :
user : user1
password : pass1
user : user2
password : pass2
user : user3
password : pass3

Xpages: send html email via java using backend document

I found this great Java Bean that allows you to send an html email including attachments via a managed java bean. It works as described when I use it directly form an Xpage.
However, I would like to use this in the backend in a scheduled agent. The problem I have run into is when I try to pass a document to the java bean. The bean is expecting (I think) an XSP document, which I don't have when in the back end, so it throws an error.
I thought I would just send the UNID of the document that I want and then change it so it would work with this bean, however, when I try to set the UNID I get an error:
Unknown member 'setUNID' in Java class 'com.scoular.utls.Email'
I am confused. Seems like this has something to do with a wrapped document, but don't understand.
Here is the faces-config:
<faces-config>
<managed-bean>
<managed-bean-name>Email</managed-bean-name>
<managed-bean-class>com.scoular.utls.Email</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
<managed-property>
<property-name>debugMode</property-name>
<value>true</value>
</managed-property>
</managed-bean>
</faces-config>
Here is a button I am using to test calling the method:
//Need to get email document
var emlView = database.getView("xpViewEmailsAll");
var emlDoc = emlView.getFirstDocument();
if (emlDoc != null) {
//try{
var subject = ""
var senderEmail = supEml
var senderName = supNme
Email.setSendTo("John");
Email.setSubject("subject");
Email.setSenderEmail("John#gmal.com");
Email.setUNID = emlDoc.getUniversalID();
Email.setSenderName("Sender");
//Email.setBackEndDocument(emlDoc);
Email.setFieldName("Body");
Email.send();
//}catch(e){
//print(e.getMessage());
//}
}
And here is the bean:

Problems with connecting to Facebook XMMP MD5-DIGEST

I have tried all the things to connect Facebook with XMPP but i have faced only
one error all the time which is :
SASL authentication failed using mechanism DIGEST-MD5 I am implementing following method to perform this task :

System.out.println(ex.getMessage ());
connection.disconnect();
}
}
but "After connect" it gone to the ctach and give me error like :
SASL authentication failed using mechanism DIGEST-MD5
I searched all blog and find same thing but i dont know what am i doing wrong here..
If is there any other way or solution to connect Facebook XMPP then please Help me
ASAP

Finally, thanks to the no.good.at.coding code and the suggestion of harism, I've been able to connect to the Facebook chat. This code is the Mechanism for the Asmack library (the Smack port for Android). For the Smack library is necessary to use the no.good.at.coding mechanism.

To use it:
ConnectionConfiguration config = new ConnectionConfiguration("chat.facebook.com", 5222);
config.setSASLAuthenticationEnabled(true);
XMPPConnection xmpp = new XMPPConnection(config);
try
{
SASLAuthentication.registerSASLMechanism("X-FACEBOOK-PLATFORM", SASLXFacebookPlatformMechanism.class);
SASLAuthentication.supportSASLMechanism("X-FACEBOOK-PLATFORM", 0);
xmpp.connect();
xmpp.login(apiKey + "|" + sessionKey, sessionSecret, "Application");
}
catch (XMPPException e)
{
xmpp.disconnect();
e.printStackTrace();
}
apiKey is the API key given in the application settings page in Facebook. sessionKey is the second part of the access token. If the token is in this form, AAA|BBB|CCC, the BBB is the session key. sessionSecret is obtained using the old REST API with the method auth.promoteSession. To use it, it's needed to make a Http get to this url:
https://api.facebook.com/method/auth.promoteSession?access_token=yourAccessToken
Despite of the Facebook Chat documentation says that it's needed to use your application secret key, only when I used the key that returned that REST method I was able to make it works. To make that method works, you have to disable the Disable Deprecated Auth Methods option in the Advance tab in your application settings.

I solved this problem. I find solution that http://community.igniterealtime.org/thread/41080

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

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();
}

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;
}

Easy way to get all the attachments from Lotus Notes using Java.
Document doc = dc.getFirstDocument();
for(var att :session.evaluate("#AttachmentNames", doc)){
if (att == null || att.toString().isEmpty()) {
continue;
}
EmbeddedObject eb = doc.getAttachment(att.toString());
System.out.println(eb.getName());
System.out.println(eb.getFileSize());
eb.extractFile("a.txt");// give file name what u want
}

Another option: if you don't mind it being a Gmail-specific solution, note that Gmail also provides an RSS feed to your mailbox, which you can then access with normal XML processing APIs.

Gmail uses IMAP, which Javamail can use. Try to use that in an implementation, and if you get stuck, post some more specific questions here.
