Question

I begun this Spring MVC Step-By-Step Tutorial part 1 at 1.8 it says

“If you are using an IDE, you will want to configure your project’s build path by adding the jars from the ‘lib’ directory. You will also want to add servlet-api.jar from your servlet container’s ‘lib’ directory (‘${appserver.lib}’). Adding these to your build path should successfully resolve all the import statements in the ‘HelloController.java’ file.”

I add jars in the ‘lib’ folder but the issues does not solves. I could not figure out how to configure the build path. Can any one help. Thanks

Answer 1

Right-click on your project root and select Build Path -> Configure Build Path.... Select the Libraries -tab and click Add JARs.... Navigate to your projects’ lib-folder and select the .jar -files, then click Ok.

Edit:
From the comment below:

can I define the library once and for every project I just mention the
path

If you have multiple projects that use the same jar-archive or archives, you can define a User library for your Eclipse-installation: Select Window -> Preferences, then Java -> Build Path -> User Libraries. Click New, give a name to your user library and click Ok. Select the User library you just added, and click Add JARs..., navigate to the jar you want to add to the library and click Ok. Note that single User library can contain multiple jars (such as all needed Spring-jars, like core, webmvc, tx…), so you can keep repeating the Add JARs... -step.

When you want to use the defined user library in your project, go to the Libraries -tab in your projects’ Build Path, and click Add Library, then select User Library and click Next. Now you can pick the library from your user libraries you’ve defined.
