find pom dependencies by classname

since version 6.1, Netbeans can add to pom.xml the dependency you need for a given class

Nexus allows you to search for artifacts by class name as well as GroupId, ArtifactId, and Version. Nexus uses Lucene to index artifacts. The Sonatype public repository allows you to search the major repositories.

Enter org.mortbay.jetty.testing.ServletTester in the search field and hit the search icon. You'll get no results because by default Nexus searches for keywords. To refine the search to match class names, select the down arrow next to the Keyword Search label on the search page and select Classname search (see screenshot). You'll then find a list of matching artifacts.

Nexus also has Opensearch integration, so you can add the search to your Firefox / IE 7 search field. See the Nexus book for more details on setting this up.

There's also a video with more details on the search options available.
