To import jar file in your Eclipse IDE, follow the steps given below.
You might not have selected either Modulepath or Classpath.
I would suggest, select classpath it will be helpful for you. A module path is a very new thing in Java 9.
Click on File > Import. The Import window will open.
Under Select an import source, click on J2EE > App Client JAR file.
In the Application Client file field, enter the location and name of the application client JAR file that you want to import. You can click the Browse button to select the JAR file from the file system.
In the Application Client project field, type a new project name or select an application client project from the drop-down list. If you type a new name in this field, the application client project will be created based on the version of the application client JAR file, and it will use the default location.
In the Target runtime drop-down list, select the application server that you want to target for your development. This selection affects the run time settings by modifying the class path entries for the project.
If you want to add the new module to an enterprise application project, select the Add project to an EAR check box and then select an existing enterprise application project from the list or create a new one by clicking New.
Note: If you type a new enterprise application project name, the enterprise application project will be created in the default location with the lowest compatible J2EE version based on the version of the project being created. If you want to specify a different version or a different location for the enterprise application, you must use the New Enterprise Application Project wizard.
Click Finish to import the application client JAR file.
You can add a jar file in Eclipse by:
right-clicking on the Project → Build Path → Configure Build Path.
Under Libraries tab, click Add Jars or Add External JARs and give the Jar.
Simple as that.
The best way is to add the jar to your project is as follows:
Create a folder called lib in your project folder.
copy all the jar files you need to this folder .
Refresh your project in eclipse.
Select all the jar files, then right click on one of them and select Build Path -> Add to Build Path
This way you can add an external jar file to your project
Eclipse -> Preferences -> Java -> Build Path -> User Libraries -> New(Name it) -> Add external Jars
Right click on your project and choose Build Path -> Add Library
Then configure the build path and you are good to go.
right click in your mouse on the project and select properties in the bottom and select build in path in the left corner and add external jar file add click apply .that's it
