Getting Pooled Connection with username and password

hi,
I am facing problems in getting pooled connections to MYSQL
database.I am using Tomcat server.
I tried the example given in Tomcat doc "JNDI how to", it
works fine with one set of username and password which is
given in server.xml. Now can anybody guide me thru the steps
to get pooled connections to the same database with multiple
username and passwords.
Thankyou all in advance

Now can anybody guide me thru the steps to get pooled
connections to the same database with multiple
username and passwords.Nope. Can't be done -- at least not that I've seen yet.
Database/JDBC driver vendors seem unconcerned, or don't
care about this scenario. I ragged on Informix years
ago for this very feature. It should would make database
admins jobs a lot easier if they could know "who" that
connection belonged to that is running the outrageous
SQL query without having to divine it by way of tracing
socket/IP connections back thru the network to some machine.
The only way I've seen to do it is to create your own
connection pool code that handles user/password connections.
-- but then the problem becomes you have a collection of
mini-pools for each user. i.e. if you have 200 users, you
end up with 200 connection pools with a couple/few connections
in each sub-pool. Kinda defeats the purpse.
So, apparently, everybody just deals with the single
"generic" user/password connection pool.

  • [SOLVED] Wireless connect with username and password

    I just recently installed Arch on my computer but have used *buntu for a couple of years so I'm not completely lost in the Linux-world.
    Anyway, my college have a wireless setup that requires you to log in with your username and password. I used wicd in *buntu but the reason I installed Arch is because I want to know how to do stuff manually, and not only automagically.
    So, the problem I have is that I don't know how to connect to it using wpa_supplicant and netcfg. I've googled about it but haven't seen any good examples, or how-to's.
    I've a profile for my home network but I only have a WPA key here so that was easy with the wireless guide, so I know some basics about wpa_supplicant anyway.
    This is what "iwlist wlan0 scan" give me:

    That did it

  • [gave-up] Connecting with username and password with nmcli

    I'm trying to connect to my university's network via nmcli. They give instructions on how to connect using the gui'ed version of Network Manager, however this is neither desired, nor at the time available to me. I've read through the wiki as well as man nmcli, however cannot figure this out. I can connect to my network at my appartment, so I know that the wireless works. That isn't the issue. The issue is just translating one to the other.

    NetworkManager can generate WPA2 Enterprise profiles with graphical front ends. nmcli and nmtui do not support this.
    I'd suggest connman, the format is fairly straightforward unlike other clients.
    (or you can generate the profile with the NM GUI on a different system, or install it temporarily)
    I swear I read the wiki. In any case, I'm probably going to almost completely deviate from the Arch way due to a lack of time needed to do things right the first time. Chances are I'll go with Antergos (still using Arch on my desktop). The only real difference, from my 2.5 months of using it, is that it doesn't start out fitting the user like a glove which is something you really only get by building your system up from next to nothing.

  • Using url with username and password in URL class

    Hi,
    I'm writting an applet in which I use getAppletContext().showDocument with an URL.
    The problem is that I'm using URLs with username and password (http://user:[email protected]/page) and it isn't working because the browser is getting the URL http://user/page.
    Is this a bug in the URL class? Or in the showDocument method?
    Is there any way to make this work?
    Thanks for any help,
    Pedro Prospero Luis ([email protected])

    I'm not sure whether this is supported behaviour. I've had this syntax fail to work in the Netscape address bar so I can't recommend it as an approach for authentication.
    If you want to authenticate the user before redirecting to the page, though, you could try creating a connection to another page on the same server and sending the authorization information then. Your browser may then be successfully authenticated.
    See http://www.javaworld.com/javatips/jw-javatip47.html for information on this.
    You might not need to read back the page from the server, just connect to it. Might work.

  • I have Iphone 4s, and the phone will activate itself again. How do I get changed Apple ID on my phone so that I get using the new username and password that is verified? I would like an answer as soon as possible ... Thank you very much.

    I have Iphone 4s, and the phone will activate itself again. This I have verified, but when I shall put this onto my phone, so the phone will not approve the newusername and password. How do I get changed Apple ID on my phone so that I get using the new username and password that is verified? Silly to buy a new phone just for this .... The phone is almost three years old. How long can weexpect this to last? I would like an answer as soon as possible ... Thank you very much.

    It sounds like your device might be in Activation Lock.  Is it asking your to enter in an Apple ID & password, but only showing you the first letter of the email address and then some dots? Example: j•••••@icloud.com?
    If so, do you recognize that email?  Do you have an Apple ID that fits the same format?  If so, then go to www.cloud.com, log in with that Apple ID & password, and see if under Find My iPhone it shows this device.  If so, turn off the device, then remove the device from the list.

    Bill - he still sees that "connection" although it isn't mapped it is attached temporarily.
    P - Log off and log back on and the attached connection will be gone.  It is temporary.   Again - knowing the basics of WIndows would let you know this.
    We have given you all of the answers that are possible.  There is no other way unless you have installed things like PowerShell and PowerShell remoting or an FTP server.
    If you do use a drive it can be just as easily deleted after you have finished the copy.
    Again: "NET USE /?" will tell you all of the options.
    Saying you know nothing is not an excuse for not thinking or looking more deeply into the suggestions made by those trying to help you.  This is not a MIcrosoft support forum or help desk.  It is a forum for admiinistrative scripting and assumes
    that those coming here are technically trained or experienced in the basics of Windows technology.

  • I cant get into itunes producer keep getting an error my username and password is incorrect. i have made a new one all good still same error any ideas?

    I cant get into itunes producer keep getting an error my username and password is incorrect. i have made a new one all good still same error any ideas?

    I'm having a very similar problem.
    I'm based in the U.K. and am trying to publish an iBook through the iTunes bookstore. I have made my book in iBooks author 2.0. My iTunes is up to date.
    When I try and publish the iBook I have passed and ticked the Pre Publish Check; and the Create Account, but when I try and download iTunes Producer through iTunes Connect I'm told "Your Apple ID does not have permission to access iTunes Content."
    When I try and re-set my iTunes Store account I'm told "The iTunes Store Account has already applied to distribute content on the iBookstore." Of course it has I just did that.
    If I try and sign in to iTunes Connect through the Publishing pane I'm told "Your ID or Password was entered incorrectly." Even though I've just used it to sign into iTunes (and here), so my password and Apple ID work fine elsewhere.
    Is my access to the iTunes Connect being delayed while my submission is processed, i.e. the processing of my tax and account details? Or am I stuck in a loop?
    If this is still processing (I started this 20 hours ago) I assume that I have to submit the book itself when I can download iTunes Producer at a later date, as I haven't submitted the book yet?
    I emailed the problem to iTunes Store and was refered to [email protected], only for them to say they don't read or reply to emails sent to that address??????
    I'm not sure which part of the process I've reached - if any. I feel I'm in limbo. I have an iBook ready to go - but where is Apple?
    Any help would be most welcome.

    Signing in with username and password every time I want to check emails on my PC using iCloud
    Having convinced my parents to get rid of their old AOL account and sign up for iCloud to sync their new iPhone with their old PC running Windows 7, I thought I was on to a winner. All working OK but is there any other way to get into emails besides going on iCloud website and signing in with name and password everytime? Can it be set up as a Mail account directly like on a Mac? Or using Outlook or Entourage? Help! I'm not a PC person!!

    If they have Win 7 or 8, and Outlook 2007 or newer then you can.
    Just download the iCloud Control Panel for Windows. Install and select the services you want (Mail Contacts and Calendars will appear in Outlook)

  • Foreign jms connection factory username and password

    I have to connect to TIBCO as the foreign JMS. I have created a foreign JMS server and configured JNDI properties including username and password. I configured a connection factory and specified username and password as well. Finally, I configured foreign destination.
              In web.xml and corresponding welogic.xml, I am using the resource-ref with Container authentication.
              With the above, I always get the following exception.
              javax.jms.JMSSecurityException: Not permitted

              The above code works fine under the following circumstances:
              * If I don't use any username and passwords.
              * If I pass the username and password to the connection factory when creating the connection. According to the documentation here (http://e-docs.bea.com/wls/docs81/jms/j2ee_components.html#1033768) doing so in an error:(
              Any ideas or suggestions?

    Even though I had configured things in the web.xml and weblogic.xml, I didn't use them. So, instead of using global JNDI, I used java:comp/env JNDI. Once, I used the correct JNDI, the connection is working... I will continue to do further testing.

  • Problem with username and password

    I've been trying to set up a new back up from scratch, and after losing my network and wifi connection, I just about have it all working again.
    I have wireless connection, and I have the TC appearing correctly in Airport Utility, green light, reporting no issues, and seemingly ready to go.
    It shows up correctly when I select disk in TM's system preferences, and it shows up and connects OK i n Finder, under shared items.
    However, when I try to initiate a backup, its reporting a problem with the username and password, even though I'm entering the correct password.
    I've checked it in the keychain, changed it in AU to be sure etc, and when I enter a wrong password, it just tells me its the wrong password, rather than this longer message explaining there's a problem with the username or password.
    So I guess it could be with the username, but not sure what that might be - any ideas?
    The only thing I can think of is that the name appears as Time Capsule b7e45c in AU, but as Iain MacDonald's Time Capsule on Time Capsule b7e45c in TM's system prefs.
    Message was edited by: Iain MacDonald1

    Exactly the same here...error 107 is reported when I try to back up.
    There are 4 computers sharing the time capsule and only one of them reports this error.
    Is there a way to remove the sparsebundle and start again for this computer without having to lose all the others?

  • Using CreateObject for Webservice with username and password

    When using createObject() to call a web service how do I pass
    in the user name and password required by the service?
    If I do a cfdump on the webservice object I see it has
    setUserName() and setPassword() methods but they don't seem to be
    working.
    I also see there are properties named "USERNAME_PROPERTY" and
    "PASSWORD_PROPERTY" but I can't seem to modify them in code. I
    suppose they are protected.
    example:
    ws = createObject("webservice", "
    http://url.to/wsdl.xml",

    ws.setUserName("myawesomeusername");
    ws.setPassword("myawesomepassword");

    FYI Adobe: this is VERY limiting, I have to use a web service

    According to the docs you can provide a username and password
    by passing a struct containing these items to CreateObject

    If you like cfinvoke use it. You can get return values by
    using the returnVariable argument. I would assume mutliple output
    parameters would be returned in a struct.
