Can I use multiple store.connect( ) in my code?

I have a mail server installed on my local comp and have created multiple users. Now I need to poll the folders of each of those users for mails and read the mails. The code is working fine for a single user but when I increase the number or users, i get a connect failed error message. I am posting the code snippet as well as the error obtained. Could anyone tell me why this is happening?
Code snippet :
javax.mail.Session session = javax.mail.Session.getDefaultInstance( prop,null);
Provider[] pro = session.getProviders();
String strProtocol = new String("pop3");
store1 = session.getStore(strProtocol);
store2 = session.getStore(strProtocol);
store3 = session.getStore(strProtocol);
store1.connect("localhost",-1,"[email protected]","user01");
System.out.println("Store1 : "+store1.isConnected());
store2.connect("localhost",-1,"[email protected]","user02");
System.out.println("Store2 : "+store2.isConnected());
store3.connect("localhost",-1,"[email protected]","user03");
System.out.println("Store3 : "+store3.isConnected());
Error :
Store1 : true
javax.mail.MessagingException: Connect failed;
nested exception is:
java.io.IOException: Connect failed
at com.sun.mail.pop3.POP3Store.protocolConnect(POP3Store.java:63)
at javax.mail.Service.connect(Service.java:227)

I don't think MU is the right tool for e-mails.  E-mail clients vary wildly even among different versions of the same software.  So building e-mails is not the same as building web pages.
Successful E-mail templates are based on tables with a limited amount of CSS and, as you say, no JS.  For best results, hand coding is really your best option:

  • How can I use multiple network connections concurrently?

    I'm using a Macbook, connected to a corporate network via Ethernet and to a private ADSL connection via Airport. What I want to be able to do is use the Airport connection for specific apps (Firefox, Safari, RDP etc) and the Ethernet connection for anything that needs to access any internal resources (Exchange etc).
    From what I've tried, the OS presents the primary connection (set via the Service Order configuration) to the application and nothing else. For example when Firefox is set to not use a proxy I can't access anything, unless the Airport is given priority. But when the Airport is set as the higher priority adapter via the Service Order then I can't access any of the internal network.
    Is there any way to work around this or am I stuck chopping and changing whenever I need to get out to the Internet directly?

    The highest priority service is the Internet connection. Anything that would go to the internet uses that service. However, you still should be able to access the internal network via Ethernet.
    For example when Firefox is set to not use a proxy I can't access anything, unless the Airport is given priority.
    That make sense
    But when the Airport is set as the higher priority adapter via the Service Order then I can't access any of the internal network.
    You should be able to at least access file servers.

  • Can I use multiple Apple store gift cards per transaction or is it has to be one gift card per transaction?

    Can I use multiple Apple store gift cards (£25 each) per transaction or is it has to be only one gift card per transaction?? Does anyone know thanks

    Hola, Eddy
    notice that you have posted to an old thread (Oct-Nov2013) that actually took quite some time to get attention back then**
    I recommend that you contact the Store Group regarding your purchase question - don't let the "iTune-ish" URL and page title throw you off... it's the right place
    Store Group - Contact Us - Apple Support
    ** next time you have a question, I advise to check the dates carefully and if older than a month or so, AND it has no answer to your specific issue, start a NEW Question. You did a fine job of stating your exact issue - many folks, not so much.

  • TS3297 Can I use multiple accounts on one device/ computer?

    I'm an American in Japan. I use the American iTunes/App store, but I also want to purchase things in the Japanese store for apps for my MacBook Pro. Can I use both stores? I have a gift card for the JP store, but no account yet. Will both be accepted on my Mac?
    I have dollars to my credit in the American store and a 10,000 yen gift card to the Japanese store.

    Unfortunately you can't do the logical and convenient thing of authorizing a computer with multiple Adobe IDs that are active simultaneously.
    You can authorize accounts from different vendors; one account per vendor.
    If you have multiple operating system users set up on the computer,  you can register different OS users as different Adobe Account users.

  • Can I use multiple credit cards with family sharing

    My kids are adults.  Can I use multiple credit cards in family sharing so they can pay for their own purchases?

    Hello Cwb1234,
    Thank you for using Apple Support Communities.
    From what I understand, you want to set it up that your kids use their own credit cards for purchases within Family Sharing. Take a look at the article linked below, it outlines purchases and payments for Family Sharing and may offer a solution to the issue that you’re running into.
    Family purchases and payments - Apple Support
    Making purchases
    After you set up your family, any time a family member initiates a new purchase it will be billed directly to your account unless that family member has gift or store credit. First, their store credit will be used to pay the partial or total bill. The remainder will bill to the family organizer's card. As the family organizer, any receipts generated by the transaction will be sent to you. Learn more about how iTunes Store purchases are billed.
    Once paid for, a purchased item is added to the account of the family member who initiated the purchase. In other words, the content belongs to them, much as it would if you were buying them a book or a DVD. If Family Sharing is ever disabled, each member will keep the purchases they initiated, even though they were paid for by the family organizer.
    These are the only current options for payment within Family Sharing.
    Regards,
    Jeff D. 

  • Can you use multiple email addresses on the owa app?

    Can you use multiple email addresses on the Microsoft OWA App?

    You can do it but there is a delay from the bluetooth speaker.  You'll need an iphone or ipad using the Apple app "Control", airplay setup, bluetooth speaker, and an Apple laptop or desktop. 
    I used my laptop to connect to my bluetooth speaker so that sound streams to my bluetooth device. Then, on my iphone I opened Control and connect the music to my airplay and my laptop at the same time.  The music goes to your airplay speaker, and then to my laptop which then blue tooths it to my speaker.  But, as I said the bluetooth takes an extra step to stream it and so the music is not in sync.  Its like a second and a half delay....

  • How can I use multiple row insert or update into DB in JSP?

    Hi all,
    pls help for my question.
    "How can I use multiple rows insert or update into DB in JSP?"
    I mean I will insert or update the multiple records like grid component. All the data I enter will go into the DB.
    With thanks,

    That isn't true. Different SQL databases have
    different capabilities and use different syntax, That's true - every database has its own quirks and extensions. No disagreement there. But they all follow ANSI SQL for CRUD operations. Since the OP said they wanted to do INSERTs and UPDATEs in batches, I assumed that ANSI SQL was sufficient.
    I'd argue that it's best to use ANSI SQL as much as possible, especially if you want your JDBC code to be portable between databases.
    and there are also a lot of different ways of talking to
    SQL databases that are possible in JSP, from using
    plain old java.sql.* in scriptlets to using the
    jstlsql taglib. I've done maintenance on both, and
    they are as different as night and day.Right, because you don't maintain JSP and Java classes the same way. No news there. Both java.sql and JSTL sql taglib are both based on SQL and JDBC. Same difference, except that one uses tags and the other doesn't. Both are Java JDBC code in the end.
    Well, sure. As long as you only want to update rows
    with the same value in column 2. I had the impression
    he wanted to update a whole table. If he only meant
    update all rows with the same value in a given column
    with the same value, that's trivial. All updates do
    that. But as far as I know there's know way to update
    more than one row where the values are different.I used this as an example to demonstrate that it's possible to UPDATE more than one row at a time. If I have 1,000 rows, and each one is a separate UPDATE statement that's unique from all the others, I guess I'd have to write 1,000 UPDATE statements. It's possible to have them all either succeed or fail as a single unit of work. I'm pointing out transaction, because they weren't coming up in the discussion.
    Unless you're using MySQL, for instance. I only have
    experience with MySQL and M$ SQL Server, so I don't
    know what PostgreSQL, Oracle, Sybase, DB2 and all the
    rest are capable of, but I know for sure that MySQL
    can insert multiple rows while SQL Server can't (or at
    least I've never seen the syntax for doing it if it
    does).Right, but this syntax seems to be specific to MySQL The moment you use it, you're locked into MySQL. There are other ways to accomplish the same thing with ANSI SQL.
    Don't assume that all SQL databases are the same.
    They're not, and it can really screw you up badly if
    you assume you can deploy a project you've developed
    with one database in an environment where you have to
    use a different one. Even different versions of the
    same database can have huge differences. I recommend
    you get a copy of the O'Reilly book, SQL in a
    Nutshell. It covers the most common DBMSes and does a
    good job of pointing out the differences.Yes, I understand that.
    It's funny that you're telling me not to assume that all SQL databases are the same. You're the one who's proposing that the OP use a MySQL-specific extension.
    I haven't looked at the MySQL docs to find out how the syntax you're suggesting works. What if one value set INSERT succeeds and the next one fails? Does MySQL roll back the successful INSERT? Is the unit of work under the JDBC driver's control with autoCommit?
    The OP is free to follow your suggestion. I'm pointing out that there are transactions for units of work and ANSI SQL ways to accomplish the same thing.

  • Can i use multiple icloud accounts on 1 device

  • How Can I Use Multiple Weblogic Instances in a Single OS

    Hello Everyone,
    Actually I have to install Some different applications. Few of them need weblogic 10.3.6 and others need 10.3.4. The OS am using is Oracle  Enterprise Linux 5.
    Now I am able to install 2 separate(One of 10.3.4 and 10.3.6) instances with two different users,In two different directories.
    I have installed the weblogic 10.3.6 version with a user webadmin and installed node manager with port 5556. This is working fine.
    The main problem here is :
    In the second instance (10.3.4 ) installed with a a different user and gave the port number to NodeManager as 1600 and its not getting started. Its throwing error and also after some errors in the terminal am able to see that its reverting to port number 5556 only.
    What might be the issue?
    I have to install 2 different versions of weblogic in a single Server. But am failing with NodeManager. What Can I do to have multiple weblogic instances with multiple versions in a single server ?
    Can anyone suggest a resolution for this please ?
    Thanks in advance.

    1. in physical connections part can i use the same work schema
    2. Can i use same contexts created or do i need to create everything as new and then try?
    Thanks,
    Rp.
    Hi,
    As you mentioned that you just upgraded the database, so the data is same and schema is same you can connect with the same work schema.
    Yes, you can use the same contexts , but need to do Reverse Engineering for your new database.
    And about data server, i think you also have no need to create new data server, if hostname,sid and port etc are same as these were with R11(consult with your DBAs regarding it)

  • Can you use multiple plugins on one piece of media?

    can you use multiple plugins on one piece of media?
    ...so for example have one plugin for a UI control bar, another for tracking, and another for advertising?
    If this is possible how? What types of plugin would each plugin be and what sort of media element would be required?
    Or is this not the correct approach? If not what would the correct approach be?
    Thanks in advance for support.

    I have got this plugin to set it's proxiedElement.
    To do so, I needed to follow David_RealEyes advice too.
    But I still can not acheive what I set out to find out, all I was trying to do was trace the current time of the videoElement, to begin to understand how plugins work. Can anyone advise please? Thanks in advance for support.
    I thought to acheive this I would just need to add  a listener for like this:
    dispatcher.addEventListener(TimeEvent.CURRENT_TIME_CHANGE,  onTimeChange);
    Then write the function like this:      
    private function onTimeChange(e:TimeEvent):void
