Jarfinder help

What's it for?

Jarfinder provides a huge searchable database of classes and jars from a wide variety of java projects. This makes it easy to resolve ClassNotFoundExceptions or NoClassDefFoundErrors

Class search

Class search allows searching by full or partial class name. A list of matching classes names will be returned - clicking on a class name will return details of the known versions of this class and details of which jars provide them. e.g.

• javax.xml.bind.JAXBContext
• com.mysql.jdbc.Driver
• org.apache.xmlbeans.SimpleValue

Wilcards

Class search supports the the wildcard character '*'. For example the search : com.*.Foo would return all classes name Foo within any package beginning with com.

If a wildcard is not included within the search terms one will be automatically appended and prepended to the query. For example the search : foo.bar will be interpretted as *foo.bar*

This behaviour can be overridden by prepending '=' to your search i.e =foo.bar will search only for classes named foo within package bar.

Jar search

Jar search allows searching by full or partial jar name.

If a '#' character is used to start the search term e.g #aa6af16380898d21e4ed56024156693a then the jars will be searched by their md5sum hash.
