I have a small Java program that uses Selenium that I'd like to install on someone else's computer so they can use it too. It uses Selenium (for what it's worth).
I exported from Eclipse to a jar file. I then used launch4j to create a windows executable. I used Java version 1.7_079 to develop the program.
The other computer has JRE version 1.7_079 installed I made sure CLASSPATH is set.
If I run this executable on my system it works fine. If I try and run it on another system nothing happens at all, no errors, no nothing.
What am I doing wrong?
Would it be easier to NOT wrap it in an executable and just use a batch file to run it?
what's the best and easiest way to accomplish this?
Try to execute the .jar directly on the system where it doesn't work by using java.exe/javaw.exe and note the error, if any.
java.exe -jar helloworld.jar
If you get "'java.exe' is not recognized..." you need to add the folder where java/w.exe is to your path (eg: SET PATH=folder-with-java-exes;%PATH%
You can locate java/w.exe files with:
cd /d c:\
dir /S java*.exe
I finally have an answer to this. I traced it down to an issue with Chrome and Chrome driver. I was running Chrome v55.0.x. The users computer was running 57.0.. Once I upgraded my machine to 57. it failed like the users did. I updated Chrome driver and everything works as expected.
you can try this in your code put the path as C:/xxxxxxxx.exe
and put selenuim and the web driver In the C drive and create a jre or exe now .
next step is to ask your client to put selenuim and the web driver also in the C drive in there computers and int will work fine .

My problem is that I want to run shell command from Java code (my IntelliJ plugin):
Runtime.getRuntime().exec("adb devices")
But then I receive IOException:
Cannot run program "adb": error=2, No such file or directory.
What is odd is that when I run it on debug mode it works, it's broken only when I deploy my plugin to real IntelliJ. The command also works from any terminal.
The only thing which works now it typing the command with full path:
/Users/adamstyrc/utils/adb
But it's not a solution. How to fix it ? My guess would be to manually load bash PATH variable add adb exec file to project but it's not elegant solution. Thanks in advance!
You need to be sure that the correct path settings are passed to IntelliJ.
If you for example modified the path settings, or if you ran intellij from a different terminal or user, then they might not be correct.
To be sure, close down IntelliJ, start a new terminal - then verify the path settings - and start IntelliJ manually from that terminal.
If you are running a 64 bit machine, try installing 32-bit libraries using
apt-get install ia32-libs
I'm having a problem with running .jar files. Here's what I've observed:
running executable .jar by doubleclicking doesn't do anything, not even start a process
running it from cmd by typing javaw myfile.jar doesn't do anything as well, I've redirected STDERR but it doesn't say anything
because of school requirements I'm developing in BlueJ, when I run my code directly from this IDE, it works and starts processes like java.exe or javaw.exe
when I try to compile my console program from cmd and then run it by java myclass, it works
I'm working on Windows 7 Professional with Java SE 7u51 JDK installed. I've already tried to uninstall anything that had "java" in its name and then install only JDK or only JRE. I've also tried to run jarfix or manually delete all .jar associations in registry. I've added my JRE path to other system variables. Nothing has worked for me.
Please do you have any idea what to try next? Thank you.
Resolved:
Thanks to the answers I've managed to resolve the problem with doubleclicking as well. I've just had to:
set the JAVA_HOME variable
restart the computer
run jarfix
Couple of quick solutions:
Use java -jar <jar-file-name>
Note: This will be useful if your jar is Runnable
Use java -cp <jar-file-name> main-class-name
Note: Specify the entry point with the class-name to start execution.
I followed the instructions on the Datomic site: http://docs.datomic.com/getting-started.html, but I'm getting this error when trying to start up the datomic shell prompt. I'm using a windows machine. Any suggestions? I tried the same thing on my linux box and did not get this error.
Edit: moved to a different windows machine and it's working. If I have time to troubleshoot this problem and I find a solution I'll report back
I noticed that you cannot run the shell.cmd from within the bin directory, you need to call it with bin\shell.cmd from the parent directory... hope that helps.
In case you are using cygwin/bash and call bin/shell :
The java runtime on windows does not understand classpath with a ":"
but this is what you get from bin/classpath.
Either correct this or use DOS-CMD shell and call bin/shell.cmd inside.

Some tips for running datomic on Windows (7 at least):
Do not download datomic into Program Files. On startup, it creates logging directories and temp files into its own directories, so unless you run the command prompt as Administrator, you're gonna have screens full of Unable to write to file... errors.
You need to run datomic as such (assuming you extracted the download to C:)
c:\datomic-free-0.x.xxxx>bin\shell.cmd
Note the backslash. Tripped me up forever coming from *nix world.
After that, return to your regularly scheduled datomic tutorials.
Hi I need to be able to check if a certain software is installed on the clients computer and where, in order to launch it. I found the following three posts as to how to do so on Windows and Mac but I can't seem to figure it out for Linux as there is no registry. Does any one know how this can be done on Linux?
Similar posts for Windows and Mac:
Can a Java applet open a "select directory" and write to a filesystem via JavaScript interaction?
read/write to Windows Registry using Java
How can I see the software installed in a Mac OS using a java application?
any help would be greatly appreciated :)
Assuming your security context allows it, you could call out to which.
$ which java
/usr/bin/java
which will output nothing if the program is not found.
Use the
which file
command to find out if the software is installed in the path. If that comes up with nothing then you could do a
find ./ -name "file"
Also check their local bin or .bin if its not included in the path.
Well, basically every binary installed on Linux is in the PATH (environment variable), so if you can find it there, it's there.
There may also be software that installs into other paths, but in this case the user would need to point them out. It is a very uncommon case to have an application in a seperate path and not adding that one to PATH.
I have written a Java GUI app (using Netbeans 6.7) requiring Java 1.6. I successfully run it on my XP PC and also my Mac OSX (10.5.7).
My client is running Vista Business, and cannot run the application by double clicking the jar file. He can execute it from the command line: "javaw -jar ..." The error received is: "Cannot find the main class... Program will exit".
I've asked the client to do the following:
install the latest JRE
run JarFix
I've verified that:
JRE is installed in correct location
jar file association is correct
application works (as I have tested it on XP and Mac OSX, and the client can run it from the command line)
Any ideas on what else I can investigate? Note, Netbeans created the main jar file, and also a lib directory with a couple of other Jarfiles. I've unzipped the jarfile and examined the manifest file (which looks good). The correct main class is also within the app's jarfile.
Does the client need to be careful as to where the application is executed from in Vista?
Thanks very much.

Does exactly the same JAR file work on other operating systems?
Is the manifest file (META-INF/MANIFEST.MF) in the JAR file correct? One catch to watch out for is that the manifest file MUST end with an empty line; if it doesn't, the last line in the manifest file will be ignored. So, for example, if the last line in your manifest file is something like this:
Main-Class: com.mypackage.MyProgram
and it is not followed by an empty line, then Java will ignore the line and it will not be able to find the main class of the program.
See Sun's Java Tutorial about deploying Java programs in JAR files for exact details about how to package your application in a JAR; it also contains the warning about the manifest file needing to end with an empty line.
Also, double-check if the right version of Java is used. Are you using the exact same version of Java as on Windows XP? Try:
java -version
to see which Java version is being used.
I'm running Vista Enterprise and have very little differences between it and other Windows versions (with regards to Java).
Here are some random ideas that may or may not work:
Have you tried: right clicking on the Jar -> Open with -> Java(TM) Platform SE Binary
Could it be permissions related? (probably not since it runs via the command line)
Have you tried it with UAC off? (UAC sandboxes java apps, and they can't write to certain locations like Program Files)
Did you make sure they have the same files as you in JAVA_HOME/lib/ext/
you could try setting environment variables:
JAVA_HOME=<your_java_home>
CLASSPATH=.
PATH=<your_java_home>\bin
Sometimes JDK needs to be installed separately,along with the net beans IDE. If you have jdk installed then you can try checking for classpath,path in the environmental variables.
