Executable jar files are a certain type of Java Archive files which can be executed on user request. 

These files show the desired output just like any other executable file.

In this tutorial, we will teach how to create an executable jar file using eclipse IDE.

Step 1 -- Use the export option

In order to create jar file in eclipse, we will use the small program of hello world. It will simply display the text "Hello World" on the screen. Now let us convert this piece of code into an executable jar file.

Right click on the project available under the project explorer and choose the "Export" option from the drop down menu.

Step 2 -- Choose the File Type

As a result, an export window will open up. As we have to create executable jar file, we will choose the Runnable jar file option inside the Java folder and then hit the next button.

Step 3 -- Name the file

Now another window will open up in which we have to specify the filename and the export destination path. 

We will name our file "runable_jar" and change the location to documents. Once done with the changes, click on the finish button. 
 
Step 4 -- View the executable file 

In order to view the executable jar file we just created, open up the location which was specified in the export window. 

In this manner, you can create jar file in eclipse.

    There are many reasons that could cause these problems, like RAM, corrupted database, path, update bugs, Eclipse bugs, etc. Without knowing the details it's hard to say for sure. You can try following these threads, for example, or explore forum for your issue: board[dot]jdownloader[dot]org/­showthread[dot]php?t=34605 daniweb[dot]com/software-devel­opment/java/threads/29365/unab­le-to-access-jarfile eclipse[dot]org/forums/index[d­ot]php/t/458349/

    U can also prepend short script to your jar file to open it via double-click $ cat > header-template <<"EOF" #!/bin/sh exec java -jar $0 "$@" > /dev/null EOF $ cat header-template "filename.jar" > executable_app $ chmod +x executable_app double-click on executable_app should run your jar-file (replace < and > by appropriate brackets)

    Try to run the program from the command line: java.exe -jar jarname.jar or: java -jar c:/dir/filename.jar (put your directory) Also, check out this article: goo[dot]gl/5cR8Fi
