  • "Java Virtual Machine Launcher-   could not find the main class"

    My system is working very slowly, especially during start-up.
    During the start-up, a small pop-up appears that reads:
    "Java Virtual Machine Launcher
    could not find the main class. Program will exit"
    Would this cause slow operation?
    How do I fix this?
    My system is Windows XP Professional, version 2002 SP1; Intel Pentium III Processor, 647 MHz, 128 RAM
    Thanks for whatever help you can offer.

    That popup message indicates that some program has tried to start the Microsoft JVM. When this occurs at startup, it often means that a spyware (or worse) program is operating. Go to this Sun site for more information.

  • Java Virtual Machine Launcher

    Hello, I've been programming in java a little while now, but lately I've been getting the error that the Java Virtual Machine Launcher cannot start. I only get this when I log into Windows XP, I can compile and run programs and applets (on web and through applet viewer no problem).
    I was under the impression that the jvm didn't start until the user started it, say by launching a java program with the "java HelloWorld" command. Any ideas what is happening on my computer? thanks

    Other places that apps can start on login:
    Registry: HKLM\Software\Microsoft\Windows\CurrentVersion\Run
    or you could have something running as a service... Do you have any ideas of what executable the error is specifically refering to?
    Re-installing the JVM is a good start.

  • Java Virtual Machine Launcher could not find the main class - program will

    I have installed J2SE and followed all the instructions but upon restarting the PC I get a dialogue box with the messege Java Virtual Machine Launcher could not find the main class - program will exit.
    I have tried multiple times un-installing and re-intalling this but i still get the messege when i restart windows.
    Can anyone offer any suggestions as to what i may be doing wrong.
    When I do the verify installation I get the congtratulations you have the latest Java Installed.
    Help

    Something is being automatically started when the pc starts. Assuming Windows, to see what it is, learn to use the msconfig program:

    Apparently, whatever it is, it's not correctly configured.

  • Error to run Configuration Wizard weblogic 12.1.2 # error is  java virtual machine launcher error could not create the java virtual machine

    hi
    Error to run Configuration Wizard weblogic 12.1.2
    my system is windows xp by 2 gig ram
    and jvm version
    C:\Program Files\Java\jdk1.7.0_25\bin>java -version
    java version "1.7.0_25"
    Java(TM) SE Runtime Environment (build 1.7.0_25-b17)
    Java HotSpot(TM) Client VM (build 23.25-b01, mixed mode, sharing)
    how resolve this problem and how find log file weblogic to this error?

    In user environments where the path to java is not already established as an system-level environment variable, the service is unable to determine where to find java and this error will occur.
    This could occur, for example, in environments where there is more than one JDK installed, or where the default JDK is different from the JDK which needs to be used by WLS.
    Try to set the environment variable  in windows  i.e JAVA_HOME=C:\Sun\Java\jdk1.7.xx.x.  to point to jdk 1.7 and run the configuration wizard.
    Hope it helps!!
    Thanks,

  • Could not create Java Virtual Machine

    Till last evening everything was fine.
    Today morning when I want to open HANA Studio I get error message
    Java Virtual Machine Launcher
    Error: Could not create Java Virtual Machine.
    What is the solution? I checked my system Java version and it seems to be current.
    Regards
    Sathish

    Hello Sathish,
    May be, some files will be missing due to deletion of some files.
    So , Reinstall JDK and JRE..

  • Osdm error 'could not create the Java virtual machine.'

    Running on Windows XP. SQL Developer reports Java(TM) Platform=1.5.0_06
    I downloaded and unzipped the osdm early adopter release,but when I double click on the osdm.exe, I get a dialog box titled"Java Virtual Machine Launcher" with the error:
    could not create the Java virtual machine.
    I'm don't know where to begin to troubleshoot this problem.
    Is there a log,trace,error file somewhere?
    Do I need something specific in my path or an environment variable set?

    Thanks Jim, for helping and the support. I'll respond to a few things in this thread for the rest of the forum.
    Feedback
    Let's start with the feedback and support. As Rene said, he is working at answering all queries coming into the feedback application. This means reviewing the issues, working with the developers and logging bugs. Each comment and query in that application is addressed and users can go back in an review the feedback for their own comments in the application too. We have had considerable interest and downloads, about which we are very excited, and this means there are lots of queries. Rene is addressing all these, and as I type, there are no comments in that application that have not been addressed. Not all are closed, as there are some outstanding issues, but each user who has submitted a comment shold have received at least one email.
    The Team
    I'm reluctant to comment about which part of the product is built in which country, but will say that SQL Developer has been a small team, with the greater percentage of developers living outside the US from the outset. I love working in the team including the wide diversity of locales and cultures and also think that because we live across multiple time zones, we can help users most times of the day or night. We are very privileged to have had the modeling team join us and I'm sure you'll get to know them in time too. If you are interested, the team stretches across a few states in the US, Ireland, Northern Ireland,England, Belgium, Bulgaria, India and China!
    Now to the problem. - Java virtual machine
    1. There is a choice of download, either with the JDK or without. If you download the build with the JDK, there should be no problem, as the product knows where to find the jdk. I'm not sure I see which of these 2 downloads was used. So that would be useful information to have.
    2. If you use the build without the JDK, then Data Modeling looking for the detail in your path.(Unlike in SQL Developer where we prompt you) You can test to see what is in your path by starting a command line, or command prompt and typing java -version. This will tell you what version of java is being looked for and used by Data Modeling.
    If you do not have a JDK, then you can download and install that as described on the download page.
    Troubleshooting
    We want to release SQL Developer Data Modeling as a standalone tool (i.e. what you are testing today) or underpinned by a repository. So our main goal is to ensure that we have a solid stable and usable product for production. The plan is to follow production with a much tighter integration to the underlying SQL Developer framework.

  • Java virtual machine error: in running bat file!!!

    Hi experts!
    I have encounterd a problem . Could not figure out why I am having this. I hope at least I will get a clue /suggestion from any of you.
    I am creating a bat file from my java Application. Then I double click on the newly created bat file to run that. It gives me Java virtual machine launcher error:" could not find the main class, Progam will exit". I have a VB script, that also create the same bat file. but I dont have problem running that file manually. Even if I create the bat file manually(by typing), it ran well. It shows the error mesage only when I create bat file from my java Application. Instead of running the bat file manually, I tried to run it through my java application too(by Runtime.exec() ). But it shows me the same error msg.
    Why am I getting java virtual machine launcher error when I tried to run my bat file that is created from java Application? ANy clue? Please suggest me about how to resolve this.
    Regards

    Probably because (despite what you say) the contents of the bat file created by your Java application aren't the same as the contents of those other bat files.Yes contents are same. I create the bat file from my java Application. then I am trying to run that bat file manually. It gives me the specified error. But if I create the bat file manually (with the same content) and then run it manually. It works well.
    Any clue/suggestion

  • Java Virtual Machine - Help

    I downloaded the JVM v1.4.2_03 and everytime I turn on my computer an error comes up. Its title is "Java Virtual Machine Launcher" and it says "Could not find the main class. Program will exit." Can someone please help me with this problem? It doesn't hurt anything that I know of, but it really bothers me so I would really appreciate the help. Thanks a lot.

    Something must be trying to run a Java program but there is a CLASSPATH error.
    Aftrer you install Java, you can click on a "runnable" jar file and it should run.
    Do you startup files somehow refer to a jar file somewhere?

  • Error message: " Couldn't create Java Virtual Machine"

    Hi,
    I recently downloaded from IBM rational application developer for websphere software v 7.5. The installation was successful. But when I try to open it, the error message:"could not create the Java virtual Machine".
    I am working on Windows Xp pro. and java is automatically updated the current version jre 1.6/
    even I tried to run eclipse from the directory c:/programfiles/IBM/SDP still same problem.
    Please some one help me how to fix it.
    Thanks.

    Do you resolve the problem? If so what was the fix?
    I have been getting the Java Virtual Machine Launcher error message “Could not create the virtual machine” when attempting to run an Oracle application that uses JNLP via a browser. Even clicking on componets such as javaw.exe produces the error message. In conjunction with receiving the error message, the application that I am working with will not launch.
    I had JRE 5u10 and J2RE 1.4.2u13 installed and thought that installing JDK 5u17 may resolve the issue. I removed JRE 5u10 and J2RE 1.4.2u13 and installed JDK 5u17 (and the included JRE 5u17.) The error message was still there.
    I have unistalled (via Add/Remove programs) and reinstalled (via both Win off-line and on-line) JDK 5u17 and JRE 5u17 many times.
    During the uninstalls I have received a Java Web Start 1.5.0_17 bad installation – error invoking JVM error message.
    I have restarted the machine also.
    There are some remains of J2RE 1.4.2u13 still on the machine –even after the 1.4.2u13 uninstall. The Java\j2re1.4.2_13\lib folder remains.
    I am running Win XP SP2 and IE6 SP2.
    Note: I cannot use Java 6 since the application that I am working with is Java 5 based.

  • Installation fails with "Cannot launch the Java Virtual Machine"

    I'm trying to install OAS 10.1.3.1. on Windows XPbut after copying all the files the installer starts complaining that it cannot lauch the Java Virtual Machine. Eventually, the process gets to the configuration step where it succeeds with one configuration, then fails with the next, and then finally goes into an eternal loop.
    When launching the installer it claims that my environment successfully passes all test for memory size, etc.
    Is this a known problem? Is there any way I can get more info about the reason why the JVM could not get lauched? I searched for information in the logs without success. I also tried to play around with the PATH environment variable since I saw some installation note saying that includingthe jre/bin path here could help, but it did not help.
    Could anyone, please, give me a hint of how to complete the installation successfully?

    Thanks for the hint.
    I had a look in the INI-file of my BPEL installation and this is what it said about memory:
    JRE_MEMORY_OPTIONS=" -mx256m"
    Still, if I start the BPEL server it finally comes up after issuing a lot of complaints but as soon as I request a page I get this:

  • SDDM 4 EA3: Unable to launch the Java Virtual Machine (Win 7 64bit)

    SQL Developer v4 EA3 is working fine, but I decided to download the stand-alone SQL Developer Data Modeler because I had seen people recommending using it in favor of the one bundled with SQLDEV.
    Windows 7 64-bit
    Java (64 bit) installed into C:\Program Files\Java\jdk1.7.0_25
    When I double-click the short-cut to start SDDM I get the following pop-up dialog error:
    Title:  Oracle SQL Developer Data Modeler
    Unable to launch the Java Virtual Machine
    Located at path:
    C:\Program Files\Java\jdk1.7.0_25\bin\msvcr100.dll
    ***NewsFlash***
    I think I stumbled on the solution just prior to posting,  so here is what worked for me in case anyone else runs into this....
    I had created a desktop short-cut to "C:\Program Files\datamodeler\datamodeler.exe", which I am guessing is the 32bit version of the binary file.   
    I was able to launch successfully by pointing to "C:\Program Files\datamodeler\datamodeler64.exe"

    That path is incorrect - strip everything after the jdk1.7.0_45\
