How to create a Jar file in Netbeans
Well I have my source code that i have done using the IDE netbeans. Now I wanted to move this java application to a web application. For that I need to create a jar file from my source code, so that I could invoke it in ma jsp file. I have not been able to find any option in netbeans or any other way to create a .jar file of this source code. Could someone tell me how to do that.
Thanks
Create a Java archive (.jar) file using NetBeans as follows:
- Right-click on the Project name
- Select Properties
- Click Packaging
- Check Build JAR after Compiling
- Check Compress JAR File
- Click OK to accept changes
- Right-click on a Project name
- Select Build or Clean and Build
Clean and Build will first delete build artifacts (such as .class
files), whereas Build will retain any existing .class
files, creating new versions necessary. To elucidate, imagine a project with two classes, A and B.
When built the first time, the IDE creates A.class
and B.class
. Now you delete B.java
but don't clear out B.class
. Executing Build should leave B.class
in the build directory, and bundle it into the JAR. Selecting Clean and Build will delete B.class
. Since B.java
was deleted, no longer will B.class
be bundled.
The JAR file is built. To view it inside NetBeans:
- Click the Files tab
- Expand Project name >> dist
Ensure files aren't being excluded when building the JAR file.
Please do right click on the project and go to properties. Then go to Build and Packaging. You can see the JAR file location that is produced by defualt setting of netbean in the dist directory.
I also tried to make an executable jar file that I could run with the following command:
java -jar <jarfile>
After some searching I found the following link:
Packaging and Deploying Desktop Java Applications
I set the project's main class:
- Right-click the project's node and choose Properties
- Select the Run panel and enter the main class in the Main Class field
- Click OK to close the Project Properties dialog box
- Clean and build project
Then in the fodler dist the newly created jar should be executable with the command I mentioned above.
