Why Cannot establish connection.

Hi,
I'm a new for weblogic and jdeveloper, and now I try to deploy FOD (http://www.oracle.com/technology/products/jdev/samples/fod/index.html) on a Linux server(Jdeveloper is running on the same server),but the connection to localhost can't be established. When I check the connection to 127.0.0.1 on port 7101, it always complains like that:
Testing JSR-160 Runtime ... failed.
Cannot establish connection.
Testing JSR-160 DomainRuntime ... skipped.
Testing JSR-88 ... skipped.
Testing JSR-88-LOCAL ... skipped.
Testing JNDI ... skipped.
Testing JSR-160 Edit ... skipped.
Testing HTTP ... success.
Testing Server MBeans Model ... skipped.
but the website: http://127.0.0.1:7101/console can be accessed, anyone knows why?
Thank you.

You are not able to establish a connection from jdev to the server right. If so you need to add an entry with the ip address and the hostname of server in the host file C:\WINNT\system32\drivers\etc\hosts.

  • Network Adapter cannot establish connection

    Hello. I can't seem to find an answer to this anywhere: I have a database that can be accessed via JDBC from certain IP addresses but not others. The ones that can't access it give me the exeception: "Network Adapter cannot establish connection" The database machine can be PINGed from the client; the IP address of the database is used so it's not a name resolution problem; we are instatiating the driver correctly...AND it WORKS from other clients!
    Does anyone have any ideas as to what the problem could be?
    Thanks.

    If there are firewalls involved, connections on port 1521 have to be allowed.

    Hi Chris,
    We have used the same because we have downloaded the driver from following location
    https://websmp108.sap-ag.de/msplatforms ;   > SQL Server > JDBC Driver for MS SQL Server (Version 3.70.10)
    I have tried with both "com.microsoft.jdbc.sqlserver.SQLServerDriver"; and "com.microsoft.sqlserver.jdbc.SQLServerDriver";, but still I am facing the same error.
    Service market place has given the driver as "JDBC Driver for MS SQL Server (Version 3.70.10)", is there a way to find out if it is for 2000 or 2005?
    Thanks for your reply.

  • Firefox cannot establish connection to server 127.0.0.1:1234

    I want to open my bank's security and it says that firefox cannot establish connection to server 127.0.0.1:1234

    I now know that a file " user.js " has been installed (probably by the Trojan) along with " user.js.BAK " in my Profiles Folder. The Support article on " user.js " says that it is never installed by default. Unless FF4 installs one (unlikely) the presence of this file explains exactly what is happening. It contains changes to the normal configuration and is read at every FF startup when it automatically transfers its content to another file in Profiles. This is " prefs.js " where all the preferences are stored. It also has a BAK file added by the Trojan: " prefs.js.BAK ".
    The above Article says these files can be read by Notepad. But mine cannot. The BAK files display pure gibberish in Notepad. The parent files cannot be opened at all. They generate a Compile error. They seem heavily protected from interference.
    Would somebody kindly tell me (1) What application normally opens BAK files; (2) Assuming I can do so, would it be OK to simply delete the user.js file and its backup?
    Even if I have to rename them first?
    With that gone, I can probably reset "prefs.js" either using "about:config" (which Preference?) or using the UI on the Tools | Advanced tab to select "No Proxy". But I am unsure about these next steps and would welcome corroboration.

    I cant update my mibile always i got the same message. An error occurrd during updating and sime times cannot establish connection ?!!!!

    Hi Martha Leal Tapia,
    Yes this issue was resolved. I had to add the below two parameters in the instance profile and continue the installation.
    icm/server_port_1 = PROT = P4, PORT = 5$(SAPSYSTEM)04, HOST = <full hostname as in the /etc/hosts file>
    icm/host_name_full=<full hostname as in the /etc/hosts file>
    Note 1158626 P4 connection to ICM on machine with multiple IPs fails.
    You can refer following SAPnote # 609603 for the above concepts although this refers to old release."

  • Whenever I try to open Firefox it says cannot establish connection, maybe your firewall is preventing us from accessing the web.

    Whenever I try to open Firefox it says cannot establish connection, maybe your firewall is preventing us from accessing the web. Even though I've let Firefox through my firewall, this message still appears. And whenever I try to redownload it, it just says installation failed. It does this with all installations... Is there something wrong with my computer? How do I fix it?

    Sometimes you only disable the user interface of security software, but the firewall or anti-virus services are still running in the background.
    It is possible that your security software (firewall, anti-virus) blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
    Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

  • Cannot establish connection (updated)

    I am trying to connect to an oracle 9.2.0.4 Database on Windows Server in shared mode through SQL Developer on Mac OS X and get only:

    trying to start sqldeveloper manually gives the following error:
    Error: Java home /System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/Home//bin/java is not a J2SE SDK.
    Running Oracle SQL Developer 1.0 under a JRE is not supported.
    If the Java VM specified by the SetJavaHome is actually a full J2SDK installation
    then add 'SetSkipJ2SDKCheck true' to /Users/einstein/Desktop/SQLDeveloper.app/Contents/Resources/Java/sqldeveloper/jdev/bin/sqldeveloper.conf
    I added this and SQL Developer starts (and looks the same like starting via the App Icon)
    I used a small Java program to test the jdbc connectivity:
    java -classpath .:../SQLDeveloper.app/Contents/Resources/Java/sqldeveloper/jdbc/lib/ojdbc14.jar TestConnection jdbc:oracle:thin:@xxx.yyy.de:1525:SID
    this works !
    But SQLDeveloper still cannot establish a connection ?

    I got it: the database server was not excluded in the proxy settings of the system network preferences!
    Now it works ...

  • Cannot establish connection with Oracle database

    Hello
    This is the first time I use BOE server with Crystal Report to execute some tests, and one issue is blocking me now, and I am not even sure if this is the right Forum where I should post it.
    I installed BOE server XI 3.1 SP4 on Linux machine (new installation), and then I uploaded some existing Crystal Report templates that are working fine on another BOE server. Those CR templates have to establish a connection with a remote Oracle database to get the data, and we pass all credentials for this purpose.
    The first time I run my first test I received this error that I could not find anywhere on the web :
    ErrorLog 2011  8 10  7:05:52.505 14215 356 (Administrator:82) (../reporthandler.cpp:12462): CReportHandler::buildReportViewerError: CSResultExceFailed to open the connection." FileName:"../reporthandler.cpp" LineNum:12458 ErrorCode:756 ErrorMsg:"Failed to open the connection.
    {FBAD55EE-BEAF-11E0-BC1C-005056813A72}.rpt" DetailedErrorMsg:""
    I believe that the CR was not able to establish the connection with Oracle, so I install Oracle Client on the same machine (test remote connection ==> pass), I set the ORACLE_HOME variable, and I edit the file <installation_home>/ bobje/java/CRConfig.xml to add the path to ojdbc14.jar, and finnaly restart the tomcat server. However I am still getting the same error message.
    Is there any hint that can help me troubleshooting this issue?
    Thank you

    do the reports use native oracle connectivity or JDBC ?
    what version of Oracle client did you install ?
    was it 32bit or 64bit client ?
    what your LD_LIBRARY_PATH variable set to ?
    what does it say in the CMC when you look at CR report's DB properties ?

  • Osx lion cannot establish connection to laserjet cp1025nw

    I have a new LaserJet CP1025nw. After working a couple of times I get an error message (it just says 'error') when I try to print. If I open the HP Utility the device is listed  but no details of device information are displayed. If I switch off and on the printer,  details of the device information appear, but then if I go to 'all settings' 'information and support' I get a message that the computer cannont establish a connection with the printer. It feels like connection is only established  briefly when the printer is first switched on. Connection is via ethernet. The lights on the back of the printer show the connection is OK, and I have tried changing the cable. 

    Did all this twice with considerable hassle. Firmware update programme would hang. Only responded when I turned printer off and on before launching it. There are some changes in behaviour. If I try to print, I get an message that just says 'error', without referrring to the driver. The HP utility is able to report device information. At what point can I say this is broken? The amount of time I have spent trying to make it work with Lion is quite inordinate (compared with less than a minute to install my old Epson C65. My options now are to (a) return it to the vendor, always difficult with an issue of this type. Or (b) smash it to pieces with a large rock to stop me wasting any more time on it. Thanks

  • Cannot establish connection

    Dear Apple Discussions,
    I have an iMac G5 with Mac OS 10.3.9 and iChat 2.1
    I am able to successfully video chat with another person (Don) with
    the exact same configuration.
    My friend Mark has a PowerMac G5 with OS 10.4 and iChat AV 3.
    I am able to successfully video chat with him.
    The problem is that Mark and Don are not able to establish a connection
    with each other.
    Mark sometimes gets an error regarding insufficient bandwidth.
    Don gets an error that a network timeout occurred.
    We all have high speed internet connections.
    We know it's not a hardware problem because I am able to chat with
    Mark and Don independently.
    What is the process for troubleshooting this problem?
    Thanks,

    HI ted7,
    Welcome To The Apple Discussion Pages.
    This tends to referred to as the Certain Buddy problem.
    It happens most often when Port Forwarding is used to open the ports. This uses Network Address Translation (NAT).
    Ther are in fact different forms of NAT and sometimes you get two modems or routers that just dont' "Play Nicely" together.
    This is what I have on the subject on my web site http://www.ralphjohnsuk.dsl.pipex.com/page15.html#CertainBuddy
    Basically the options are to change the way the ports are opened if they can.
    Note: The bottom line is to try another modem.
    This samll app can help identify if it is a NAT problem NATCheck

  • Cannot establish connection with SQL server from SQL developer

    Hi, I recently downloaded SQL Developer version 3.0.04 and am trying to establish a connection to a remote SQL server. The database was created on this server by someone who is no longer working on the project. I have been given the username, password and server name. Is there another piece of information I am missing? I keep receiving the error:
    Status: Failure-Test failed: IO Error: The Network Adapter could not establish the connection.

    Check out the SQL Server network configuration. When instances are used the port on which the SQL Server is listening on might be different. Use the networking utility from the SQL Server and check out the SQL Server network details.

  • I cannot connect to my basic SQL server from Visual Studio Ultimate 2013? Error 40 - Cannot establish connection

    I just started learning ASP.NET through a book, and it asks to connect to "your" SQL server and explore a .mdf file. I've been trying to install SQL, but I only just now got a working installation, and even then it won't let me install the Management
    Software. Whenever I try to connect, I get this error: http://puu.sh/7F2JY.png
    This is exactly what I do to connect:
    1) Open project
    2) Navigate to the Server Explorer
    3) Click on connect to database
    4) In this menu, I can see me Machine name on the top part, which I think means that it's picking up my server runningh
    5) On the bottom, it wants me to enter a database name. I think this may be my problem, as I have no idea what to do here.
    Also, when I double click on the database file, I get this errpr (52): http://puu.sh/7F2Yw.png
    I really don't know what to do here, so post any tips down below

    Hi,
    Did you choose the correct Server name? It should be the machine name where you installed SQL Server on.
    Is it empty when you open select or enter database name drop box in the Add connect dialog box in the Visual Studio 2013?
    “Update: I re-installed, and then used both installers. Now I have the Server Management tools, but I still cannot connect.”
    The screenshots indicates that the SQL Server is not accessible.
    Do you mean that you are not able to connect SQL Server by using SQL Server Management Studio?
    If so, make sure that SQL Server Services is started.
    Please check out the following articles for details:
