Using Javamail to get attachments

Good Morning,
I have been working on this project for a few days now and have ground to a halt. Downloading attachments seems to take forever and it would appear to be at the writing file to disk line. I have read about many options (FileChannel, bulk getContent and a few others but can not make this code execute at a reasonable rate) I am not to sure if the only bottle neck is the downloading of the files from O365 however I thought I would ask a question to see if somebody could review this code and hopefully tell me what I have done wrong. The goal of the application is to log into Exchange Online (o365) and download all attachments within a certain mail box. Please note that this code has been modified so many times to see if I could make performance increases by using threading and so on:
As I said I have shifted everything around a lot to try and make this work better so please don't blow me up for some of the code not making too much sense. I am not trying to get somebody else to finish this project, I am looking for guidance with a language that I do not have a great deal of experience with.

Edit:
props.put("mail.imaps.fetchsize", "819200");
props.put("mail.imaps.partialfetch", "false");
sped things up, 128 seconds down to 12 seconds to download a 7mb file.

fetchsize is not used if partialfetch is false; it will download the entire attachment in one request. As long as you have enough memory for the largest possible attachment, that's fine. Otherwise, leave partialfetch set to true (default) and set the fetchsize large enough to give reasonable performance without using excessive memory.
JavaMail properties are described in the javadocs, on the page for each protocol provider. For example, the IMAP provider properties are described on the com.sun.mail.imap package javadoc page.

java.lang.ClassCastException: java.lang.String cannot be cast to com.tutorial.stateful.Book

since I m trying to test a stateful EJB i got the "java.lang.ClassCastException: java.lang.String cannot be cast to com.tutorial.stateful.Book" error.
my client code looks as follow
import com.tutorial.stateful.LibraryStatefulSessionBeanRemote;

} catch (NamingException ex) {
ex.printStackTrace();
}
brConsoleReader =
new BufferedReader(new InputStreamReader(System.in));
}
public static void main(String[] args) {
EJBTesterStateful ejbTester = new EJBTesterStateful();
ejbTester.testStatefulEjb();
}
private void showGUI(){
System.out.println("**********************");
System.out.println("Welcome to Book Store");
System.out.println("**********************");
System.out.print("Options \n1. Add Book\n2. Exit \nEnter Choice: ");
}
private void testStatefulEjb(){
try {

LibraryStatefulSessionBeanRemote libraryBean =
(LibraryStatefulSessionBeanRemote)ctx.lookup("ejb:/EjbComponent//LibraryStatefulSessionBean!com.tutorial.stateful.LibraryStatefulSessionBeanRemote?stateful");
while (choice != 2) {
String bookName;
showGUI();
String strChoice = brConsoleReader.readLine();
choice = Integer.parseInt(strChoice);
if (choice == 1) {

bookName = brConsoleReader.readLine();
Book book = new Book();
book.setName(bookName);
libraryBean.addBook(book.toString());
} else if (choice == 2) {
break;
}
}
List<Book> booksList = libraryBean.getBooks();
System.out.println("Book(s) entered so far: " + booksList.size());
int i = 0;
// Exception line-trigger
for(Book book:booksList){
System.out.println((i+1)+". " + book.getName());
}
LibraryStatefulSessionBeanRemote libraryBean1 =

}finally {
try {
if(brConsoleReader !=null){
brConsoleReader.close();
}
} catch (IOException ex) {
System.out.println(ex.getMessage());
}
}
}
}
the statefull ejb class looks like:
#Stateful
public class LibraryStatefulSessionBean implements LibraryStatefulSessionBeanRemote{
List<String> bookShelf;
public LibraryStatefulSessionBean(){
bookShelf = new ArrayList<String>();
}
public void addBook(String bookName) {
bookShelf.add(bookName);
}
public List<String> getBooks() {
return bookShelf;
}
}
is ther any idea to solve this casting issue.
Many Thanks
thanks, your responses were helpful to avoid the casting problem after some changes in stateful Bean class:

getBooks returns a List of Strings not Books
List<String> booksList = libraryBean.getBooks(); // as you've already done for booksList1
for (String book: booksList){
....
}

If you see the following error message
java.lang.String cannot be cast to com.tutorial.stateful.Book
it is very clear that you are assigning an object which is a String to an object which is a Book. This is impossible because there is no relationship in between these two classes. So, a String class cannot be cast to a Book type.
It will raise a ClassCastException.
The problem occurs in this line of code
List<Book> booksList = libraryBean.getBooks(); //this line will throw an exception, because it returns a List<String> not List<Book>.
// Exception line-trigger
for(Book book: booksList){
System.out.println((i+1) + ". " + book.getName());
}
because
public List<String> getBooks() { //returns a List<String> not List<Book>.
return bookShelf;
}

To add a listener follow the steps described here in the "Listening" section. It displays information message from cvs to the user.

How to get list of JNDI Names from Weblogic Server?

I am getting the list of datasources configured in context.xml of Tomcat Server using the method below :
public static List<String> getDataSourcesList() {
List<String> dataSourceList = new ArrayList<String>();
try {
if( initialContext == null ) {
initialContext = new InitialContext();
}
NamingEnumeration<NameClassPair> list = ( ( Context )initialContext.lookup( DATASOURCE_CONTEXT ) ).list( "" );
while( list.hasMore() ) {
dataSourceList.add( list.next().getName() );
}
}
catch( NamingException ex ) {
Logger.getLogger( JDBCUtil.class.getName() ).log( Level.SEVERE, null, ex );
}
return dataSourceList;
}
But this method does not work for Weblogic and Websphere Servers.
How can I get the list of datasource names configured on the Weblogic/WebSphere Servers ?
Is there any method to get the list of datasource names ?

For WebSphere Application Server just use dumpNameSpace command line tool located in PROFILE_ROOT\bin
And your code with small modification is working fine in WAS 8.5.5:
try {
InitialContext initialContext = new InitialContext();
NamingEnumeration<NameClassPair> list = ((Context)initialContext.lookup( "jdbc" ) ).list( "" );
while( list.hasMore() ) {
System.out.println(list.next().getName() );
}
}
catch( NamingException ex ) {
ex.printStackTrace();

how to solve The import com.atlassian cannot be resolved?

Hello I am trying to develop my web application using jsp. I have 6 jsp pages in it. Pages are registration.jsp, login.jsp, r1.jsp, welcome.jsp, createroom.jsp and showroom.jsp respectivly. My goal is that when i login in login page, page should redirect in openmeeting server. For that i have created webservice like omRestService. For calling this Service i have created two java class omGateWay and OmPluginSettings respectivly. Everything works fine but error occurs in ompluginSetting class.error mention below.
import com.atlassian.sal.api.pluginsettings.PluginSettings;
import com.atlassian.sal.api.pluginsettings.PluginSettingsFactory;
(The import com.atlassian cannot be resolved)
Here I am Providing you my OmPluginSeeting.java file which has error. There are many errors occur at PluginSettingsFactory.
