Establish socket connection with local pc using Applet

Hi,
I want to write an applet embedded in my web application.
When I access the web application from my PC which is connected to a RFID reader, I need the applet to make a socket connection to the attached RFID reader.
Is this allow?
If not, what do I need to make this possible for applet?
Please advise.
Thank you.

HI Helen,
Just to check.
He is on XP ?
He is using AIM 5.9 ?
He has Tuned the camera and Mic to the App ?
If he is at Service Pack 2 he has enabled the app through the XP firewall ?
You have the MAc firewall Off.
The ports are enabled in your modem.
Either using UPnP or these actual ports
5060, 5190, 5678, 16384-16403 for just the AIM stuff.
Have you changed the Quicktime setting to match your download speed ?
Can you and he get any of the people or test accounts o this page ?

  • Error establishing socket. Address already in use

    Running CFMX 6.1 on Win2k3, I just recently started getting
    these errors from connections to one of our SQLServer database
    servers (2000, enterprise):
    quote:
    Error Executing Database Query.[Macromedia][SQLServer JDBC
    Driver]Error establishing socket. Address already in use: connect
    Any ideas what might cause this?

    ok. well, if you think that was useless, you might as well
    not read on... this isnt a coldfusion error. it only appears that
    way because you are using cfml. this is a most probably an SQL
    issue. i say most probably, because there are many reasons this
    could be happening. try doing things in these steps as they are in
    degrees of harshness.
    1. check the server event log, see if you have an entry like
    this
    'You are running a version of Microsoft SQL Server 2000 or
    Microsoft SQL Server 2000 Desktop Engine (also called MSDE) that
    has known security vulnerabilities when used in conjunction with
    the Microsoft Windows Server 2003 family. To reduce your computer's
    vulnerability to certain virus attacks, the TCP/IP and UDP network
    ports of Microsoft SQL Server 2000, MSDE, or both have been
    disabled. To enable these ports, you must install a patch, or the
    most recent service pack for Microsoft SQL Server 2000 or MSDE from

    install sp4
    [L=http://www.microsoft.com/sql/downloads/2000/sp4.mspx]http://www.microsoft.com/sql/down loads/2000/sp4.mspx[/L]
    2. change your database server name to its IP (if that doesnt
    work, you might as well change it back)
    3. make sure you are authenticating with an SQL account.
    windows integrated authentication does not work well ... in your
    SQL enterprise manager, set it to mixed authentication in the
    security tab, select SQL server and windows authentication. the
    microsoft driver seems to not handle the windows authentication
    properly. i wouldnt use the the SA account, create another one just
    for this purpose.
    4. under the general tab in your enterprise manager click
    network configuration. enable TCP/IP which is not enabled by
    default
    5. Install SQL Server 2000 sp3 or sp4

    Hello, I have a sql 2005 server, and I am a developer, with the database on my own machine.  It alwayws works for me but after some minutes the other developer cant work in the application
    He got this error
    Login failed for user ''. The user is not associated with a trusted SQL Server connection. [CLIENT: 192.168.1.140]
    and When I see the log event after that error, it comes with another error.
    SSPI handshake failed with error code 0x8009030c while establishing a connection with integrated security; the connection has been closed. [CLIENT: 192.168.1.140]
    He has IIS5 and me too.
    I created a user on the domain called ASPSYS with password, then in the IIS on anonymous authentication I put that user with that password, and it works, on both machines.
    and in the connection string I have.
    <add key="sqlconn" value="Data Source=ESTACION15;Initial Catalog=GescomDefinitiva;Integrated Security=SSPI; Trusted_Connection=true"/>
    I go to the profiler, and I see that when he browses a page, the database is accesed with user ASPSYS, but when I browse a page, the database is accesed with user SE\levalencia.
    Thats strange.
    The only way that the other developer can work again on the project is to restart the whole machine. He has windows xp profession, I have windows 2000.
    If you want me to send logs please tellme

    Well here's my problem, maybe you can help. Intermittenly I get a login failed when connecting to a db engine through Server Management Studio using Windows authentication. When this happens the following entries are generated on the server's application event log:
    Event Type:        Error
    Event Source:    MSSQLSERVER
    Event Category:                (4)
    Event ID:              17806

    Description:

    User:                     N/A
    Computer:          <server name>
    Description:
    Login failed for user ''. The user is not associated with a trusted SQL Server connection. [CLIENT: <ip address>]
    I've already ensured that the server is set to mixed authentication mode. Oddly enough, the workaround that I've found is that if I remote desktop into the server, log in and then log back out, Management Studio is suddenly able to connect again. No idea why it works. 
    As I said before, it is intermitten. Some days it errors on login, other days it doesn't and there are no configuration changes between them. Also, both client and server are in the same domain and same site so there is no VPN or anything in between. I'm really quite stumped. Any help would be great, or if you can point me in the right direction of where to look. Thank you in advance!

  • The network adapter could not establish the connection with Oracle

    I installed Oracle in my laptop (windows 2008), and install Hyperion 11.1.2, when I configure Hyperion, it pops up with "the network adapter could not establish the connection with Oracle"?

    Hi,
    This usually means that the connection details you have put in for Oracle are incorrect or Oracle can not be contacted.
    Double check your configuration connection details and make sure you can access Oracle using them details.
    Cheers

  • Could not establish secure connection with server

    Hi ,
    We are not able to access our web service URL from Ipad Application on some of the network. We are receiving “could not establish secure connection with the server” message. We are able to access the same URL from other networks. Can you please suggest what can be possible Root cause and their suggested solution?  We would appreciate your quick response..

    hi Alfonso,
    Editing the hosts file is easy. just need to use the CAS/CAM CLI and the vi test editor. You can google for instructions on how to use Vi.
    To start assume we have a CAM and CAS with the hostname cam1 and cas1 respectively. the domain is mycompany.com and the ip addresses for the CAM and CAS is 192.168.10.1 and 192.168.15.2 respectively.
    start with the CAM and view the hosts table
    cat /etc/hosts
    To check what domain u used to setup the CAM
    cat /etc/resolver.conf
    edit the hosts file so appears like so
    192.168.10.1 cam1.mycompany.com cam1
    192.168.15.2 cas1.mycompany.com cas1
    Verify with 'cat /etc/hosts'
    Make sure you can ping 'cas1' and 'cas1.mycompany.com' from cam1
    Next edit the hosts file for cas1 so that it appears like so
    192.168.15.2 cas1.mycompany.com cas1
    192.168.10.1 cam1.mycompany.com cam1
    Make sure you can ping 'cam1' and 'cam1.mycompany.com' from cas1

    When you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site.
    (1) Bypass Firefox's Cache
    Use Ctrl+Shift+r to reload the page fresh from the server.
    (You also can clear Firefox's cache completely using:
    orange Firefox button ''or'' Tools menu > Options > Advanced
    On the Network mini-tab > Cached Web Content : "Clear Now")
    (2) Remove the site's cookies using either of these. Save any pending work first.
    While viewing a page on the site:
    * right-click and choose View Page Info > Security > "View Cookies"
    * Alt+t (open the classic Tools menu) > Page Info > Security > "View Cookies"
    Then try reloading the page. Does that help?

  • Can not establish a connection with SQL

    hey all,
    i was trying to start with JDBC ,but i spent two days trying to establish a connection with SQL.
    can anybody help me please, the problem is about the url string and driver name.
    am completely lost with these stuff :(
    thnx in advance,

    stillAbeginner wrote:
    am using Microsoft SQL server 2005, but i don`t know how to get or setup driver correctly.
    please explain how.
    Are you specifically using "localhost" as the server name and thus the database is on your client box? If not then SQL Server must be configured to accept such traffic before it will work.
    Other than that the most common problems are
    1. The port is wrong. It is either 1433 or 1434.
    2. The server name(or IP) is not visible from client computer. Nothing you do in java nor MS SQL Server will fix this.

  • SAP Connection with a Website using HTTPS

    SAP Gurus,
    We are on SAP 4.7.  Requesting you to revert whether it is possible to connect SAP 4.7 with HTTPS (Secured) thru some BAPI or BADI.
    Details:
    1. The Business Process expected to be set is for Vendor Transactions.
    2. That is, the Vendor liability document is expected to be posted from the data that would flow thru Internet HTTPS.
    3. The request would originate from a website (that is NOT SAP).
    4. It would have the Vendor Party credentials.
    5. The Line Item Data would come to SAP thru HTTPS and it is expected that SAP would accept the request and process it.
    6. After successful process of the file, the system would generate Accounting Document.
    7. This Accounting Document is expected to be sent back to the originator website, using the same HTTPS connection.
    8. The entire leg is expected to be completed in 180 seconds.
    Qs:
    a. Is it possible to achieve this with using some BAPI or BADI?
    b. Whether it is possible to connect to SAP with some RFC (RFC may not be the right technical word, please recommend what else) using the Secured connection, that is HTTPS?
    Many Thanks

    Hi,
    Thanks for ur reply.
    I am facing the following problem.(I am using Https protocol)
    1.A runtime exception is thrown at line no 5. This is the main problem i am facing and as i am not able to establish the connection with the server, i was able to proceeed further.
    2. I need help for setting the content type(Remember i am using Https)
    3. As u said at server side file has to be decompressed but that is not under my scope so it is not a problem for me.
    4. once connection is established, I need to create a byte stream and write to destination and then i have to check the response sent by the server.
    I am looking for an idea how to establish the connection with the server. any references let me know.
    Code written by me:
    URL url = new URL("https://www.sun.com");
    URLConnection conn = url.openConnection();
    conn.setRequestProperty("content-type","Application/x-zip-compressed"); // I dont think this is correct way of setting the header var
    conn.connect(); // an exception is raised here
    conn.setDoOutput(true);
    OutputStream ostream = conn.getOutputStream();

    You can simply publish to the RTFMP stream both are connected to. Ryan Stewart once came up with this: http://tv.adobe.com/watch/tech-talk-with-ryan-stewart/build-a-chat-application-with-adobe- stratus/
    But besides you could of course only use a netgroup and send messages to neighbors with notifies.

  • Establishing a connection with a database

    Hi,
    can you tell me in which way I can establish a connection with a database?
    I'm working on NetBeans 5.5 and I put a database called "Object List" in its databases editor. I established a connection in that editor, but I don't manage to call that database from the source program and work with it. I'd need the statements and methods to do it.
    Thank you

    I can't tell you the exact statements because you do not share which DBMS you are using. But the classes to look into are:
    DriverManager

    Are you using the Derby module in Netbeans by any chance?
