Trouble connecting debugger to local process

I'm using JDeveloper 10.1.3.1.0 on WinXP SP2 with Java 1.5, running a JSF/EJB 3.0 application on the embedded OC4J server. About 90% of the time, I try to start the debugger on a JSF/JSP file, and JDeveloper is unable to connect the debugger. I tried selecting a Debugger Port Range of 4000 - 4999, but this doesn't seem to make any difference.
Here's the output when the debugger fails to connect:
[EJB 3.0]: Assigning default-data-source=jdbc/SmashExpressDS, specified in projects EJB 3.0 properties

Thanks in advance for any help.

Me too. Running on fresh Fedora Core 6 Linux and jdev 10131 and jdk1.5.0_09. Until recently I ran on SuSE 10.1 with 1013 and had no problems. I've added "AddVMOption -Djava.net.preferIPv4Stack=true" to jdev.conf to avoid ipv6 problems and disabled firewall and selinux. Watta f is dis? Problem is narrowed down to plain "hello world"... Error looks like:
/home/local/java/jdk1.5.0_09/bin/java -hotspot -Xdebug -Xrunjdwp:transport=dt_socket,server=y,address=4004 -classpath /home/jms/Documents/Projects/FileShare/Client/classes no.jmsconsult.fileshare.client.file.DirectoryClimber

    Earlier, I was able to debug the application. Since last few days, facing the issue
    Please suggest, if you have any.

    Hi,
    Thanks for your response .
    Sorry for delay in response. Actually I was on vacation since last few days.
    Finally able to fix the issue. Issue is due to change in C:\Windows\System32\drivers\etc\hosts file. It's been updated for some other reason. Now I've updated the file with required changes. Now able to fix the issue.

  • Debugger unable to connect to local process

    I am going thru the JDeveloper Introduction Tutorial and when I try to debug the application I get the following error in the message window:
    C:\JDev\jdk\bin\javaw.exe -ojvm -XXdebug,quiet,port1069 -classpath C:\JDev\jdev\mywork\MyFirstApp\MyProject\classes myproject.Dog

    I am using Windows XP Professional
    JDeveloper 10.1.3.4.3673
    If I just run the application then it works.
    I also have the Sun Java JDK installed, as well as Eclipse and NetBeans installed.
    I tried reinstalling JDeveloper but the debug function still does not work.
    Any help will be highly appreciated.
    Thanks,

  • Debugger disconnected from local process.

    When I debug my source code I set a breakpoint and from there use step into or step over two to three times and then debugging stops with the message "Debugger disconnected from local process." I set the breakpoint at different positions and always had the same effect. When I run the code that part I try to debug does work.
    What can I do to debug that part (want to watch certain variables in that part)? I already tried to set more breakpoints and used resume to step to the next breakpoint, but again debugging stops.
    Thank you very much for your help,
    C.D.

    Hi Carola,
    The message "Debugger disconnected from local process." is written to the log window when the debuggee process terminates.
    In your case, it sounds like the debuggee process is terminating unexpectedly early (perhaps because the JVM died). To figure out why that is happening, I'll need to know some more information:
    What kind of program are you debugging? Is it a Java Application with a main method? Or, is it a Servlet or JSP? Or, is it an EJB? Or, an Applet?
    If your program is small, would it be possible for you to send it to me so that I can reproduce the problem myself?
    What J2SE version and what JVM are you using? The J2SE is specified in the Project Settings dialog on the Libraries panel. The JVM is specified in the Project Settings dialog on the Runner panel.
    If the problem you are seeing turns out to be a bug in the JVM, you can probably work around it by switching to a different JVM. Again, this is specified in Project Settings dialog, on the Runner panel. If you are currently using OJVM, you could try switching to HotSpot (also called Client). However, you will notice that debugging is much faster with OJVM than with other JVMs.
    Also, what platform are you running on? Windows NT? Windows 2000? Windows XP? Linux (what kind of Linux and what version)? Solaris (what version)?

  • Trouble connecting Reporting Services to local database

    I am experiencing issues trying to configure/connect the Reporting Services in order to change the database to a local database.

    Hi Ralph,
    According to your description, it seems that you are trying to connect to a local database when create a data source in a Reporting Services report.
    If in this scenario, in the Connection Properties dialog box, we can type . or localhost or server_name in the Server name textbox. Then select the database, Windows Authentication or SQL Server Authentication to log on the server. For more details,
    please see the following blog:

    The local Admin Password was reset to the "original" (after install) one.
    Any ideas how to fix the problem?

    Dear all,
    the encryption was NO on all protocols.
    Because no additional ideas available, i uninstalled the SQL Server on friday.
    At the Re-Install Process i got again an error:
    [Microsoft][SQL Native Client]Shared Memory Provider: No process is on the
    other end of the pipe .
    The install process failed.
    On google i found the same problem in an other thread:
    http://groups.google.com/group/microsoft.public.sqlserver.connect/browse_thread/thread/dbec4a9a271f69a6/7cd22694da3a6062?lnk=st&q=%22Shared+Memory+Provider%3A+No+process+is+on+the+other+end+of+the+pipe%22&rnum=2&hl=en#7cd22694da3a6062
    ++++++
    During the installation process of SQL Server 2005, Setup complains it cannot
    connect to the database service for server configuration. The error was:
    [Microsoft][SQL Native Client]Shared Memory Provider: No process is on the
    other end of the pipe .
    I have checked that the pipe exists (\\.\pipe\SQLLocal\MyInstance), but
    everytime the installer attempts the connecting the pipe is closed by the
    server and another is reopened. That's why the Client says there is no
    process on the other end of the pipe.
    I have re-installed 'everything', tried connections via TCP, but nothing
    works.
    I have made a small application to connect to the pipe and noticed that
    there are 3 instances of the pipe running, one that I am connecting to, and 2
    listening pipes. If I write to 'my' pipe SQL server disconnects the pipe and
    reopens another too. The difference is that SQL server writes an error
    message in the log file. No such luck when the Native client is doing the
    same.
    What more can I do?
    ++++++
    and an answer
    ++++++
    I finaly found the problem to be the certificate used.
    I noticed that a certificate was added to the machinekeys just recently.
    (in C:\Documents and Settings\All Users\Application
    Data\Microsoft\Crypto\RSA\MachineKeys)
    I renamed it to another name and re-installed sql server.
    I noticed that sql server ERRORLOG complained about certificate that it
    couldn't load and the generation of a self-generaed certificate (see below)
    "2005-12-10 21:01:02.30 Server      The server could not load the
    certificate it needs to initiate an SSL connection. It returned the following
    error: 0x8009030d. Check certificates to make sure they are valid.
    2005-12-10 21:01:02.49 Server      A self-generated certificate was
    successfully loaded for encryption."
    Now the installation succeeded
    ++++++
    With Windows 2008 it was really a challange to get access to this folder (!!!)
    After clearing the folder the ReInstall of SQL Server works fine.
    Now the SQL Server & the SQL Server Agent works again.
    The problem was anything with encryption, old certs & files.
    I don't think that everyone can afford reinstalling SQL server.
    I finaly found the problem to be the certificate used.
    I noticed that a certificate was added to the machinekeys just recently.
    (in C:\Documents and Settings\All Users\Application
    Data\Microsoft\Crypto\RSA\MachineKeys)
    I think this is what the following blog was saying , a problem with certification

  • I am having trouble connecting my iPad mini with my lap top that run Xperia

    I am having trouble connecting my iPad mini with my lap top that run Xp

    Hi..I've had a variant of this problem; my internet was accessible but my devices on wifi could not see the PC on Lan. That meant no iTunes syncing, Airplay from iTunes etc.
    Dlink has a strange default setting that isolates Wifi & Wired connections into different subnets.I'm assuming you have DHCP setup on your router and you're PC or MAC has internet access via the same router. Try the following steps to see if this solves the problem for you-
    1. Go to Setup -> Local Network  and Uncheck the box that says 'Configure the second IP Address and Subnet Mask for LAN' - Hit Apply
    2. Go to Wireless -> Wireless Basic and Uncheck 'Enable MultiAP Isolation' - Hit Apply
    3. Restart your Router
    Let me know if this solves your problem. I've been frustrated by my problem for months & had nearly given up.

  • Trouble connecting my N96 to my PC

    Having trouble connecting my N96 to my PC using the supplied USB data cable, each time I connect the phone to the PC via the data cable the phone tries to connect to the web and the PC can not detect that the phone is connected.
     I haven’t tried to restore factory settings as am unable to backup all the data on the phone.
     Would appreciate any help and advice from anyone, as have also been advised that I need to update the frame ware on the phone. Which I can’t do as unable to get the PC and phone to communicate with each other.

    Hey @Satisfied1,
    Welcome to the HP Support Forums!
    I understand that you need assistance installing your HP Deskjet 3052A e-All-in-One Printer on your Windows 7 computer. I would like to assist you with this today. Now I see that you've been trying to add your printer in via the 'Add a Printer' feature to no avail. Unfortunately, if you want to have full functionality of your printer for both printing and scanning, adding a printer via 'Add a Printer' is not practical. This is used to add older printer models with the built in Windows Drivers. Because your printer is still relatively new you have the option to download and install the HP Full Feature Software and Drivers. I will walk you through the install process below.
    Please click here to download the appropriate drivers for your printer
    Once the website opens select the Download button
    Allow the download to Run
    Follow any onscreen instructions to reinstall your printer
    Do not plug in your USB Cable until the installation prompts you to
    Once the installation is complete your printer should show in the Devices and Printers folder. Please test your printing function to ensure that your printer is working properly.

  • Having Trouble Copy and Pasteing Local Variable in LabVIEW 2010

    I am Having Trouble Copy and Pasteing Local Variable in LabVIEW 2010 in s subVI.
    I have a VI that has a Local Variable called "Node Addr". I can select it OK, and it appears to Copy OK, But when I go to paste it, nothing appears. It doesn't matter if I use Cntrl-C Cntrl-V or the Copy and Paste from the Edit menu, I get the same results. I tried many times and got the same results. I made sure that I had click a paste location. I can insert the Local Variable if I use the Data Communication panel.
    On one of the Paste, I got an error in the error list that said that a Local Variable was not connected to anything. When I clicked on the error, it took me to an insible item in the lower right corner of the block diagram that had nothing but a select box around it. I couldn't select the invisible item, but I could delete it.
    Why does the copy and paste of this local variable not work?
    Why does the paste cause the insertion of an invisible item?

     My VI is fairly complicated. In several places in the VI, I am either reading or writing to this variable which is an numeric Indicator on the Front Panel. Using local variables seems to be the best way to handle this situation rather that using wiring all over the VI. Since the VI is mainly a State Machine and there are only 2 Writes to the local variable, I am not afraid of race conditions in this case.  NO!! While you may think that using Locals is your solution to wiring, it is not!  The fact that you are writing and reading, most likely from several places, will most definitely contribute to a race condition.  Depending on your implemetation, you should ALWAYS use wires.  The wires are the variable.  If you are using a loop (While, For), then using shift registers are appropriate means for routing values so that they are used by other sections of the code, later.  One thing you must respect with LabVIEW is the dataflow.  That's where Locals often fail.
    I am not copying the Local Variable from one VI to another.
    I am not copying the Local Variable from one VI to another.
    The Data Communication panel is one of the panels that shows up in the Functions pop up list when editing the Block Diagram. It is the panel that includes the Local Variable function.
    I don't know if the invisible item that was inserted in my block diagram was hidden or not. All I know is that the Errors List said that it was a Local Variable and that it was not connected to anything. I couldn't select it to get more information. All I could do was delete it.
    You did not address my questions about why the Copy and Paste does not work properly for my Local Variable.  Maybe it's a sign from the Software Gods not to use them LOL!..
    So if I understand correctly, you are trying to copy & paste the Local Variable from within the same VI.  How large is your block diagram?  Did you try right-click on the variable and select "Find > Local Variables"?  If it's a block diagram larger than 1 single screen (which it shouldn't), then it is possible that the Local is hiding beyond the screen.  You should find it as I described earlier.
    See my comments in red above.

  • Trouble connecting to AFP over VPN

    Hi All,
    I regularly connect to my office server via VPN and use an AFP connection to mount share points (or VNC to share the screen).
    Via the same VPN tunnel I also connect to my desktop machine at work using AFP or VNC. Recently, after upgrading my office desktop computer to Yosemite I began having trouble connecting from my home laptop (MBPR running Yosemite as well). I try to connect and get the message "There was a problem connecting to the server xx.x.x.xx" HOWEVER, using that very same VPN connection I am always able to connect to the server at work; just not to my desktop now.
    Both the office server and my office desktop have fixed IP addresses and are on the same subnet etc. At one point I was able to solve the problem and the AFP connection to my office desktop machine worked again for awhile, but then once again stopped working. I've checked that our VPN is assigning valid IP addresses to my client at home, but it still is problematic.
    I'm pretty familiar with our whole system since I'm our low-rent IT guy, and it has functioned smoothly for my team for years -- but I am not terribly knowledgeable of the deeper issues of networking. Because the issue arose after I upgraded my office desktop to Yosemite I feel it must be related to the new OS and how it manages file sharing or something (although I will reiterate that I did have it successfully working at a couple different times, it just seems to stop working for no apparent reason). Oh -- one more thing, I AM able to connect to my office desktop via AFP from other local machines within the office so I know it's File Sharing services are working correctly.
    Any guidance or ideas welcome

    What's the actual exception message? Your URL looks fine to me, though maybe something is not right with the host portion, hard to tell. It could also be a database set-up issue (e.g., your Oracle instance right now is only accepting connections from localhost).

  • IPad trouble connecting to wi-fi network

    Have 2nd generation iPad1 w/ latest iOS.  Can not recognize or connect to a local wi-fi network which my iMac (located in the same room) has no trouble connecting with.  Any ideas? 

    Usually it's because you are not making internet connection via wifi.

    Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.

  • Trouble connecting to my wireless internet

    Hello,
    I'm having trouble connecting to my wireless internet. We have a linksys wireless router, and I know the MAC filter is turned on, so I've added my computer to the router, and I've put the password in correctly, but it keeps saying there is an error connecting to the network. All my other roommates have PC's, this shouldn't be a problem? My Mac should have no problem connecting to this modem, right?
    Thanks

    Hello jennhie,
    You can download the firmware at your router manufacturer's homepage. Look for download>firmware
    If you are not familiar with the process, download the manual as well. It will be very helpful in the update process.
    Hope this will help
    Good luck

  • App World issues. "having trouble connecting to BlackBerry App world Server" and "installation issue"

    Hey.... I hope this isn't just repeating the 'same old' issue, but I have read through everything I could find and I am still having no luck.
    Anyways I am having a few issues.....
    ONE/// When I try to go to "My World" on my Playbook it always comes up with the message:
    BlackBerry App World is having trouble connecting to the Blackberry App World Server,  Verify your network connections and try again.
    One solution I read was to connect to an alternative WiFi connection, however I haven't got any other connection I can connect to before switching back to my own.... help?!
    TWO// There are also two games I have been desperately trying to install but have had no luck.  Each time all I get is the following message:
    Install Error. There was a problem during Installation.  Please try again.
    I have read the KB26671 file, and tried to follow the 'resolution' there but whenever I log in I never get any 'account set up process' to continue with..... let alone what the rest of the guide says to do.
    THREE// Not sure why but when I try to use AppWorld on my PC it won't show me my playbook device, simply says "please connect your device".... help?  According to my playbook it is connected to computer, and my PC is picking up the Playbook as the manager always tells me it is there and lets me view the files but still AppWorld can't seem to see it.
    Thanks in advance for your help.
    Solved!
    Go to Solution.

    Well I was just trying to see if it was your network connection. I have found that lately anyhow, the connection to the App World hasn't been that reliable - not sure why and it's just been recently for me. But I have downloaded some pretty large files in the last few days too without issue.
    Sorry, this isn't much help but if you find your network connection is becoming flaky, remove the profile and setup a new one. Sometimes I find I have to briefly shut off my internet connection on the PlayBook and then re-enable it when it's acting up. Then things are fine afterwards. A device reboot may help but it may not. I wish I could be more help but this gremlin sounds elusive.
    Actually, duh, why didn't I put two and two together eariler? See if this thread is applicable to you or not: http://supportforums.blackberry.com/t5/BlackBerry-PlayBook/PlayBook-not-letting-me-update-apps/td-p/...
    In short, reboot your PlayBook and try again...
