I've written some code and made a .jar file out of it, and I want to be able to run this code from the start=>run box in the Start menu. After a lot of trial and error, I made sure to construct my .jar file the right way, and I set the proper .jar file type association so that my computer recognizes to run the .jar file using java.exe.
Doing all this enabled me to run the .jar from the command window, typing "java -jar myJar.jar", but it won't run from the start=>run box (even when I add in the .jar's filepath). What should I do?
Also, I'm not sure if I could run a .jar from the run box that takes arguments - is it possible to do that?
You'll need to tell Java which class to is the main class. If you intend to distribute the application you should probably make a Manifest file with a main-class attribute.
See: http://download.oracle.com/javase/1.4.2/docs/guide/jar/jar.html#JAR%20Manifest
If you just want to get the damn thing running, this command should work...
java -jar myJar.jar MyClass
... analogous to how you'd normally write...
java MyClass
... at the command line.
BTW, it might be worth mentioning the javaw command, which which works just like the java but launches a graphical application without showing a command prompt, on Windows.
You should have a look at the links below:
http://download.oracle.com/javase/tutorial/deployment/jar/basicsindex.html
http://download.oracle.com/javase/tutorial/deployment/jar/manifestindex.html
You probably did not add the the "Main-Class:..." in your manifest file.

You have to have a special entry in your MANIFEST.MF file inside your .jar that points to the entry point class in your .jar file to make it executable without specifying a class on the command line.
META-INF/MANIFEST.MF
Manifest-Version: 1.0
Main-Class: [fully qualified path to the class with the main method]

I have downloaded the ninja-win.zip folder and extracted it. When I open it, there is a single .exe file in the entire folder. When I double click it a cmd window flashes for a split second. I have also tried running it as administrator, but the same thing happens. What I don't understand is, what am I expected to do with this .exe file?
You must open a terminal (cmd.exe on Windows) and type something like ninja -f /path/to/buld/file. You may also wish to modify the PATH environment variable so that Windows knows where to find the Ninja executable, depending on your setup.
You can simple download ninja.exe file from this Link
https://github.com/ninja-build/ninja/releases
After that you just have to add the path to your ninja.exe file to your windows environment variables and then you can use ninja commands from anywhere in windows.
1. Open cmd in your Project Directory
2. There are guides on the internet on where to save the Ninja.exe so that it'll be callable in Cmd without specifying directory. Either follow them or:
i, Specify Directory when Calling Ninja. Putting "ninja" in Cmd actually calls Ninja.exe and is the same as something like "C:\users\user1\downloads\Ninja". or:
ii, Save Ninja.exe in the same directory as Project.
3. proceed with rest of the command.
Therefore the Final Command would be:
"C:\users\user\downloads\Ninja.exe" -f "D:\Projects\Project1"
I have create a project in which I am trying to generate a .txt file and then calling OS specific commands (I'm using unix so using system() function to trigger application) to open it in default application.
My code works perfect.
But the problem starts when I try to run my application after setting it in environment path. I am doing that for global visibility. File gets generated correctly by while opening the .txt using system() seems like it is trying to look at it at different directory.
I want to some how convey to the system() function to look at the specific location.
How can I solve this problem?
It sounds like you are actually just in a different working directory. Try showing the result of getcwd.
I have created some Java applications to extend Rhapsody using Java API and I have deployed them successfully to the Rhapsody environment (Right click on the project -> Apps).
I can see the exported .jar files under the directory RhapsodyApps/apps.
My question is, How can I run them from the command line (Under windows 7)???
Thank you in advance
What I managed to do is to create a .bat file, using "Generate Apps Execution Batch File". As I mentioned in my last post it did not exist in the "Apps" menu of rhapsody. Besides, it existed in the "...\share\RhapsodyApps\apps" directory with the name "SynchronousScriptInvocation.jar". I hardcoded the RhapsodyApps.hep file, by adding the following:
#REM: This app generates a script which will invoke each app synchronously one after another. ...
name7=Apps\Generate Apps Execution Batch File
isPluginCommand7=1
command7=Apps
applicableTo7=Project,SysML,AUTOSAR_40,AUTOSAR_31,AUTOSAR_32,DDS,UPDM1_DoDAF20,UPDM2_DoDAF
isVisible7=1
I got the name (Generate Apps Execution Batch File) from the AppInfos.xml file.
Then, the plugin is displayed in the Apps menu in Rhapsody IDE, and I can generate the .bat file. Problems did not stop here. The batch file was not displaying my plugin and the reason was something with my JAVA_PATH configuration. Finally I modified the .bat file as following:
#rem This is auto generated script. Be careful on changing it manually.
#rem Build Order
set APP0=0df8829923eb43f4aab9d33ada1ddbf1
#set APPS= %APP0%
set JAVA_PATH=%JAVA_PATH%\bin\java
set JAVA_API=C:/work/User/Build.TRUNK/ProjectName/RhapsodyShare8/JavaAPI
set RhapsodyApps=C:/work/User/Build.TRUNK/ProjectName/RhapsodyShare8/RhapsodyApps
set CLASS_PATH="%RhapsodyApps%"/apps/RhapsodyAppLauncher.jar;"%RhapsodyApps%"/RhapsodyApps.jar;"%RhapsodyApps%"/apps.jar;"%JAVA_API%"/rhapsody.jar
"C:\Program Files (x86)\IBM\Rational\Rhapsody\8.0.5\jre\bin\java" -cp %CLASS_PATH% -Djava.library.path="%JAVA_API%" apps.RhapsodyLauncherApp %APPS%
Finally it works. I hope that this post will help somebody in the future.
I wanna create a exe which has the Shell Script and Simple CPP file which calls the Shell Script using system() function. Lets say exe name 'myInstaller' which has files myintsaller.cpp and myShell.sh. When i run the exe myInstaller , it must execute shell script. I want to do like this so i can protect my Shell Script code ,which has over 3000 lines of Code.
How do i do this ... I m in real need of this.
As far as i've searched, there is no way to bundle the script inside the exe. Either it would be Shell Compiler as shelter suggested or plain shell scripts. No work around for this.
I guess it's Windows platform since you speak about exe. In this case you can add your script as a resource to your exe, extract it in run-time and execute.
You could keep the script as a string in your C++ code and call system("sh -c '" + code + "'"). Quoting may be an issue though. Otherwise, write it to a temp location, execute it and then unlink it.
I am looking for some documentation or tutorial for copying files from a given directory into the app created by xcode at build time, before it is run.
At first I have tried to copy files into the derived directory, hoping that everything resides in there would be automatically added to the app, but I was wrong.
So I am looking for a script because the original dir may change its name, second the script could be customized by another xcode 4 user with its src dir path etc.
The things is I don't know how to start, which language etc. I am quite confident with shell script, but maybe there's a better option.
Second, I am trying to figure out which command could add a file in the already built app.
thanks
That answer didn't really help - the BUILT_PRODUCT_DIR isn't where most stuff goes.
Ultimately, I found you just need to do:
Add the following to the very end of your script (or get your script to write directly to the output location):
cp ${DERIVED_FILE_DIR}/[YOUR OUTPUT FILES] ${BUILT_PRODUCTS_DIR}/${UNLOCALIZED_RESOURCES_FOLDER_PATH}
...but there's a lot of other things I tried. More thoughts and ideas here: http://red-glasses.com/index.php/tutorials/xcode4-a-script-that-creates-adds-files-to-your-project/
You want a Run Script or Copy Files build phase. Select your main project in the navigator, then select the app's target. Click the Build Phases tab. Click the Add Build Phase button at the bottom of the window and choose the appropriate phase.
By "appropriate" I mean if you really want to run a script, you'll use a Run Script build phase and use Xcode-provided environment variables like $BUILT_PRODUCT_DIR (see the documentation or hit build and examine the full output of an empty script in the build log) to figure out your target folder. If all you want to do is copy files (no real processing), the Copy Files build phase already knows how to locate the app bundle's proper folders depending on what you're copying (Resources, Frameworks, etc.).
