How can I add JAR files to the web-inf/lib folder in Eclipse?

Question

I\'m using Eclipse and I need to be able to add Java libraries (JAR files) into my web application\'s WEB-INF/lib folder. How do I achieve this?

Answer 1

1. add the jar to WEB-INF/lib from file structure
2. refresh the project, you should see the jar now visible under the WEB-INF/lib folder.

Answer 2

Found a solution. This problem happens, when you import a project.

The solution is simple

1. Right click -> Properties
2. Project Facets -> Check Dyanmic Web Module and Java Version
3. Apply Setting.

Now you should see the web app libraries showing your jars added.

Answer 3

From the ToolBar to go Project> Properties>Java Build Path > Add External Jars. Locate the File on the local disk or web Directory and Click Open.

This will automatically add the required Jar files to the Library.

Answer 4

Pasting the jar files in WebContent\WEB-INF\lib via the file system was the only way it worked for me.

They then appeared under the Deployed Resources and WebContent lib sub-folders.

When I looked, the build path had the jars in the Web App Libraries and everything built and ran fine.

Answer 5

Check under project properties -> deployment assembly if jar file are under deployed path- WEB-INF/lib if not use add button and add jar under WEB-INF/lib

sometime eclipse (in my case Juno Service Release 2 ) was not doing it for me so i did manually. this worked for me.
