I have Nodejs - server.js code in my windows system from which i want to execute a simple jar file.
So i used follwoing code :
cmd = "java -jar C:\\libs\\sample.jar";
var Exec =exec(cmd, function(error, stdout, stderr) {
if (error !== null) {
console.log('exec error: ' + error);
}//end of if
});//end of exec cmd
When i run the "node server.js" in command prompt ,jar is executing perfectly.
After this i made this "node server.js" command as service by referring following link :
https://github.com/coreybutler/node-windows
i.e node-windows,But now once its become service i am unable to exectue simple.jar,even i am enble to run simple "java -version" command.
Except java all other command are working fine even after i made nodejs as service.
Please help me out.....

I tried JAVA bridge to get output from my jar file followed this https://stackoverflow.com/a/10253798/1870048, I am using XAMP Server and from that Apache and Tomcat server is been used
require_once("http://localhost:8080/JavaBridge/java/Java.inc");
$cartObj = Java("Cart"); //Javav("Cart");
$cartObj->Cart("098765");
$cartObj->setLang("EN");
echo $cartObj->getLang();
but gives error :
Fatal error: Call to undefined function Javav()
What should I exactly I look into?
Also I tried below way also to call the jar file by placing the jar file in my zampp htdoc folder: (D:\xampp\htdocs\jar)
// Using shell_exec
exec('java -jar AutoDiscounts.jar '.$jsonRequest.' 2>&1', $result);
print_r($result);
// Using shell_exec
$arg1 = $jsonRequest;//"My_INPUT_PARAMETER";
$output = '';
$output =shell_exec("java -jar AutoDiscounts.jar $arg1");
echo "Done calling shell exec:";
echo $output;
But both above cases does not give any output .Basically my jar will do some cart processing and return output and it works in the JDevloper
Following Getting started -
(Windows 7, console: C:...>, .jar & .javauto in the same folder)
java -jar javauto.jar => OK, help is displayed
javauto hello.javauto => command not recognised
javauto.jar hello.javauto => NO result
So i tried this
java -jar javauto.jar -v hello.javauto
Giving this exception (NB: c:...>javac => help display is OK)

Try this:
1) Compile it using this command:
java -jar javauto.jar hello.javauto
2) Now that you have compiled your program, there will be a file called hello.jar. Execute with:
java -jar hello.jar
I got a task to run R script in java, so I used the JRI library for this case, and I need call it from jsp, so I write a page simply call by
Runtime.getRuntime().exec("java -Djava.library.path=/home/XXX/R/x86_64-pc-linux-gnu-library/2.15/rJava/jri/ -cp /home/XXX/R/x86_64-pc-linux-gnu-library/2.15/rJava/jri -jar /home/XXX/MyJar.jar")
This method -> re.waitForR() always return false
Rengine re = new Rengine(new String[] { "--vanilla" }, false, null);
if (!re.waitForR()) {
System.out.println("Cannot load R");
return;
}
But when I run with console
java -Djava.library.path=/home/XXX/R/x86_64-pc-linux-gnu-library/2.15/rJava/jri/ -cp /home/XXX/R/x86_64-pc-linux-gnu-library/2.15/rJava/jri -jar /home/XXX/MyJar.jar
It is good and no error happened!
How can I do?
PS. My Jsp runs on Jetty.
I recently bought a Macbook Air and it's now running Mountain Lion, but i have some problems running the company's project, the only other person using a mac on work runs Lion on his Macbook Pro and he had no such problems.
As the title says theres no problem compiling the project on the command line, but when i try to compile it inside IntelliJ i get this error
[ERROR] Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.2.1:exec (requireJS-Optimizer) on project MarfeelTouch: Command execution failed. Cannot run program "node" (in directory "/Users/pedrompg/Documents/Marfeel/MarfeelTouch"): error=2, No such file or directory -> [Help 1]
The problem also happens when i compile it from the command line and try to run the program
Caused by: java.util.concurrent.ExecutionException: java.io.IOException: Cannot run program "phantomjs" (in directory "/Users/pedrompg/Documents/Tenants/vhosts/discoverint"): error=2, No such file or directory

at com.marfeel.pressSystem.impl.SectionPressImpl.getAllItemsFromSectionFeeds(SectionPressImpl.java:137) ~[MarfeelPressSystem-1.0.jar:na]
... 29 common frames omitted
It seems that i can't run any command line programs from inside the project
This is how we the phantomJS call:
private Process buildProcess() throws IOException {
Process process;
String[] invocationCmd = getInvocationCmd();
if (executionDirectory != null) {
if (LOG.isDebugEnabled()) {
LOG.info("Invoking PhantomJS with {} in {}.", Arrays.toString(invocationCmd), executionDirectory);
}
process = Runtime.getRuntime().exec(invocationCmd, null,
new File(executionDirectory));
} else {
if (LOG.isDebugEnabled()) {
LOG.info("Invoking PhantomJS with {} in {}.", Arrays.toString(invocationCmd));
}
process = Runtime.getRuntime().exec(invocationCmd, null);
}
return process;
}
the getInvocationCmd() returns the following array
[phantomjs,--load-images=no,--disk-cache=yes,--max-disk-cache-size=1048576,/Users/pedrompg/Documents/Marfeel/MarfeelHub/target/webapp/WEB-INF/classes/whiteCollar.js,marca/marca.js,http://www.marca.com/]
Don't know if i leave any relevant information
We use Maven, tomcat 7, nodeJS, phantomJS 1.5, nginx 1.2.4, java 1.6.0_35 on the project
Hope someone can help, i'm getting really worried about this, already wasted 2 days trying to solve this problem.
Thanks in advance
As you are using Mac, it's most likely environment related issue. Please note that on Mac GUI applications do not inherit Terminal environment variables, therefore if you have adjusted PATH variable and command works from the Terminal, it will not work when you try to run from other applications.
See the related questions about this Mac feature. Pay attention to the second link, Mountain Lion has different behavior for environment variables.
The easiest way to verify that it's the case and workaround the problem is to run IntelliJ IDEA from Terminal:
open -a /Applications/IntelliJ\ IDEA\ 11.app/
This way Terminal environment will be passed to IDEA and commands you can run from Terminal will also run from IntelliJ IDEA.
I have a python compiled script (script.pyc , I haven't the .py file)that work well from my windows command prompt, and I want to execute it from my Java's application.
I tried to use runtime() method :
Runtime runtime = Runtime.getRuntime();
runtime.exec(new String[] {"C:\\toto\\tools\\script.pyc" ,"arg","arg2" });
but I get an error :
Exception in thread "main" java.io.IOException: Cannot run program "C:\Nuance\VoCon Hybrid\SDK_v4_3\tools\clctodict.pyc": CreateProcess error=193, %1 n?est pas une application Win32 valid
The script work well in my terminal ("arg" is a txt file, "arg2" is the output name, and the script does its job without any problem).
I also try to launch my script with getDesktop() :
File fie = new File("C:\\toto\\tools\\script.pyc" ,"arg","arg2");
Desktop.getDesktop().open(fie);
There is no problem, but I can't add argument, so I can just see a terminal windows opening during a few second before disappearing instantly.
I have also tried to use JPython, without success too (maybe we can't use methode "execfile" on a .pyc????)
You can do something like
Process p = Runtime.getRuntime().exec(new String[]{"python.exe" ... other args)
Then you can invoke p.waitFor() to wait for the end of the process and p.exitValue() to test if the program exited successfully.
You can also get the output stream via p.getOutputStream() to retrieve the text printed by your python script
Please refer to the class documentation for further information : http://docs.oracle.com/javase/6/docs/api/java/lang/Process.html
Just like you need a jvm to run a .class, you need a python interpreter to run a .pyc.
Try something like:
runtime.exec(new String[] {"c:\\Python26\\bin\\python.exe", "C:\\toto\\tools\\script.pyc" ,"arg","arg2" });
