Recently I worked on a project done in the network visualization and analysis software Gephi, and I saved it with the ".gephi" extension. However, when I try to reopen the file, it gives the following error message:-
"The project file couldn't be opened. Please check the file has .gephi extension.
XMLStreamException - ParseError at [row,col]:[1,1]
Message: Premature end of file."
I'm a beginner in Gephi and only an amateur programmer. I do not understand this error message, and thus have no ideas on how to resolve it. I tried updating Gephi to the latest version. I also tried to open the file from within Gephi. Neither of those steps have resolved the problem. Can anyone help me out with this, please?
The error message "premature end of file" means that the xml file was not complete. I suppose that the whole file is empty or just the xml part of the file. so maybe the file got corrupted while saving.
Can you try to open the file with notepad or a hexeditor to verify that it has some content?
There must be some bug on the gephi files writing or reading process.
In order to identify the problem it would help if you can post a gephi log file when each error happens.
You can find the log file on gephi user directory (check http://wiki.gephi.org/index.php/Troubleshooting)
For example in Windows 7 the path is C:\Users\Your_User\AppData\Roaming.gephi\dev\var\log\messages.log
Also, if you can share the files, it will be easier to fix.
This could be related to an open bug where Java6 is used to save the gephi file and then Java7 is used to load the file, say on a different machine.
The jdk used by Gephi can be specified in /etc/gephi.conf or alternatively it can be specified as a parameter --jdkhome when launching Gephi.
The problem is with java and javac:
If you created your gephi file with open java-6-openjdk (for example) and then you sitch your java to java-7-openjdk, then this problem surges.
I fix my gephi returning to the same java and javac executables in Linux by:
(In terminal)
sudo update-alternatives --config java
and then
(In terminal)
sudo update-alternatives --config javac
Hope this can help!

I'm trying to run this code from : https://github.com/pnnl/safekit ,using cmd on windows 10, I already installed python.
when I type the command:
tar -xjvf data_examples.tar.bz2
I keep getting the error:
tar: Error opening archive: Can't initialize filter; unable to run
program "bzip2 -d"
I have tried to download bzip2 through easy-7 zip and GnuWin32 , but it didn't work.
Can any one help me?
P.S.: I did search for the same problem before posting mine.
If you run the command in git bash instead of cmd it should work.
I've run into the same problem! My non-elegant solution so far has been to force Windows's tar.exe to use the bzip2.exe provided with my Windows Git installation. The trick is to add to your user PATH the directory where bzip2.exe is located, in my case:
C:\Program Files\Git\mingw64\bin
So, right now my PATH looks like:
Path=%USERPROFILE%\AppData\Local\Microsoft\WindowsApps;C:\Program Files\Git\mingw64\bin
Notice that I've only touched the user environment PATH, not the system PATH, and I've appended the new directory. As always, touching your PATH can be a little bit dangerous, proceed with care. If someone has a better solution, I'd be glad to hear it.
Note: I tried copying the bzip2.exe to a separate directory, but this didn't work (I presume because bzip2.exe couldn't find some dependencies).
After extracting the Pentaho zip file I downloaded. I set my class path to JDK 1.7.0. But, upon running the Spoon.bat file I keep getting the statement: "Unable to launch your Java Virtual Machine (JVM)." How do I resolve this problem ?
NB: I have configured JAVA_HOME, JRE_HOME as stated by similar previously answered questions.
Note that Pentaho7 requires java 8.
In any case, Set the PENTAHO_JAVA_HOME=dir, where dir is the directory that contains the /bin/java.exe executable.
Alternative:
The spoon.bat [resp spoon.sh] runs first the set-pentaho-env.bat to find a suitable java. Edit this file to know in which order it searches for it. So do like me, when nobody looks at you, edit this file manually, and set _PENTAHO_JAVA_HOME and _PENTAHO_JAVA manually.
To check: In a command line shell, cd to your PDI install directory and type spoon.bat. It writes something like start "Spoon" "**some\directory**\javaw.exe" more stuff. Check that you can type **some\directory**\javaw.exe -version in your shell.
If not: in the same directory, type set-pentaho-env.bat. It writes down the PENTAHO_JAVA and PENATHO_JAVA_HOME thAt spoon will use. Edit that file until %PENTAHO_JAVA%\java.exe -version and %PENTAHO_JAVA_HOME%\java.exe -version answers the appropriate version.
In my case (for PDI 9.2.x), installing an Oracle JDK 8 solved the issue (no need to set the Java home folder explicitly)
I am trying to build libccid, pcsclite and libusb together on a fedora 20. I have been able to compile and build libusb and pcsclite. However, while building libccid, I get the following error in the build log:
copy the src/92_pcscd_ccid.rules file in udev directory (/etc/udev/rules.d/)
I did copy the file to the specified location and then ran the makefile. However, I have not had any success.
Did anyone come across this error message?
Thanks
When you check the libccid source code you will find out that it is not an error message. It is just an informational message that you should manually copy file 92_pcscd_ccid.rules from src directory to /etc/udev/rules.d/ directory.
I have installed PyDev successfully, I have python 3.4.0 installed successfully and the folder containing python.exe is in my path and I can run it from the command line.
However, when I go to window\preferences\pydev\interpreters\python interpreter and select 'quick auto-config' to configure it using normal python I get an error saying 'auto configurator could not find a valid interpreter... Note the system environment variables used for Jython are PATH and PYTHONHOME.'
Unless this is a bug in the text I am not selecting Jython (I get a different error if I select IronPython, btw, so this is not a generic error message).
The trace is as follows:
Errors getting info on discovered interpreter(s).
See error log for details.
java.lang.RuntimeException: java.io.IOException: Cannot run program "python": CreateProcess error=2, The system cannot find the file specified
As I say, python.exe is in my path.
You have to install the actual python package separately from here https://www.python.org/download
Close LiClipse/Eclipse => Download Python Here: https://www.python.org/download
=> reopen LiClipse => Auto Config for the interpreter Will WORK!
I found the answer, but I'll leave this up in case anyone else gets it. It's a pretty stupid auto config option if you ask me ;)
In the higher level window\preferences\pydev\interpreters\ preference you need to untick jython and ironpython.
No idea why given I selected the Python sub-preference specifically.
Here is the related error its showing:
java.exe is not a recognized file as an internal or external command,
operable or external command
errorlevel=9009
i was getting the same error on WIndows 8.1(64 bit) and checked java path but it was ok
so i just run my jmeter.bat with Run as Administrator and it worked for me
Many operating systems have an environment variable such as PATH that contains a list of directories (or folders) to be searched when looking for a command to execute. Commands that can be found via the PATH are commonly called external commands. The program that reads the command line or the batch file and invoked the commands may have a number of built in commands, these are commonly called internal commands.
I suggest you examine the PATH (or equivalent) set when your java command executes from the command line and also when execution is attempted from the batch file. Compare the two and make sure the directory containing your java.exe is in the PATH.
Does not work with Java 9 beta:
Running:
C:\java -version
Gives:
java version "9-ea"
Just go into command line and run:
java -jar ApacheJMeter.jar
Set the correct Java Path (installed in your system) in Computer -> Advanced System settings -> Environment Variables -> Ok -> System Variables -> Path
I got the same issue and resolved by following the above steps.
I tried everything, this eventually worked.
Within System Variables:
PATH = "C:\WINDOWS\system32;C:\WINDOWS;C:\Program Files\Java\jdk1.8.0_101\bin"
May help someone.
This error occurs due to the path has not been set properly.
Either you can set it in environmental varialables or right click jmeter .bat file,choose edit set the path their,for reference see the jmeter.apache.org user manuals.
For me, my Java path has a space in it and jmeter said it can't find Java
/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home
.. I looked at the jmeter.sh script and saw it got the path from "Plugin-Ins" .. onward. I tried just commenting out the exit command after that check in the script .. and then I was able to run jmeter.
So apparently the validation logic has a bug, where the error message about can't find java is in fact not true (if Java is indeed set up correctly), so it can be ignored.
For windows 8.1 Users:
Error when trying to run jmeter.bat
Error message:
Not able to find Java executable or version. Please check your Java installation. errorlevel=2
Press any Key to continue
Resolution:
Right Click jmeter.bat and Run as Administrator.
This worked for me, hope this helps. Good luck
Set the correct JM_LAUNCH variable to java.exe
For Windows XP users set Java environment by following the steps here:
http://www.tutorialspoint.com/jmeter/jmeter_environment.htm
Note the path depends on your installed JDK.
And download the file from:
https://svn.apache.org/repos/asf/jmeter/trunk/bin/jmeter.bat
Then replace your jmeter.bat with the downloaded file.
If you have installed Java and still you get this error, please set the java_home path to below using typing below command in terminal:
export JAVA_HOME="/Library/InternetPlugIns/JavaAppletPlugin.plugin/Contents/Home"
Since I run many versions of Java.. I modified jmeter.bat.
rem JM_START - set this to "start" to launch JMeter in a separate window
rem this is used by the jmeterw.cmd script.
rem
rem =====================================================
setlocal
rem Minimal version to run JMeter
set MINIMAL_VERSION=1.8.0
set PATH=%PATH%;C:\Program Files (x86)\IBM\Java80\jre\bin <<< add This line to jmeter.bat
Copied the JAVA executable from Installed version of Java from C:\Program FilesJava\jdk1.8.0_191\bin and pasted in the folder where the jmeter bat resides and it worked for me.
Not exactly the same issue but somebody might find it helpful
Do not double click jmeter.bat but instead ApacheJMeter.jar in the same directory
For me jmeter.bat run but for a brief moment closing almost immediately and not prompting any error. Above workaround allowed me to start working
if JAVA -version shows as blank or empty in the command prompt (CMD) then you need to clear the all java paths in environment variable and again add JAVA_HOME=C:\Program Files\Java\jdk-11.0.15.1
path= C:\Program Files\Java\jdk-11.0.15.1\bin;
if you see C:\Program Files\Common Files\Oracle\Java\javapath; like this remove this
and try in new CMD prompt then Java -version will work.
