Adding Jar File to WEB-INF/lib

Question

I new in Eclipse,Java and Linux. I search about this issue but I don't reach to answer. I want to write a program that manipulate HBase Tables. So I have some Jar files that they related to the HBase. In ordinary Java application I add Jar files through following instruction

Build Path -> Configuration Build Path -> Add External Jars

So in Dynamic Web Project sound like different. after some search I understand the Jar files must be added in WEB-INF/lib or in %TOMCAT_HOME%/lib. so I get answer from %TOMCAT_HOME%/lib but really stuck about how to add jar files in WEB-INF/lib. I copy all jar files in the folders but it doesn't work.

please help me in detail.

you are doing right....

Build Path -> Configuration Build Path -> Add External Jars

In "Order and Export" tab click on select all...

or coping file into WEB-INF/lib

Then just refresh your project and restart the server then deploy the project it will work fine...

according to first it will give an exception at run time – Achyut Oct 09 '13 at 11:48
I know this is from a while ago, but is there any reason that copying jars into WEB-INF/lib would **not** work? I'm running into an issue where the jars are available on the filesystem, but not visible in eclipse. – drognisep Nov 21 '16 at 20:44

To add jars in eclipse you have two options:

Right click on project got to properties-->click on java build path --> configure build path--> Libraries --> and select add external jars button. It will open a window where you can add all your jars required.
Second option is to paste jars directly to lib folder. lib folder is in Web Content --> WEB-INF --> lib.

Use any one of them.

If a path to the jar file is too long it will not paste that jar file.

Paste the jar file on the desktop and try again.

This works for me.

You can copy jar files manually to WEB-INF/lib when you have your project open in eclipse, then while modifying build path, just click "add jars" button and refer a jar from WEB-INF/lib . By this when you deploy your project to tomcat, your WEB-INF/lib folder gets copied automatically.
