Re: Best/recommended way to search if a Java library or class is packaged

[Sergio Fernández]

I always use the following bash-based solution:

dpkg -l | grep java | awk '{ print $2 }' | xargs -I {} dpkg -L  {} | grep
jar | xargs -I {} grep "javax.servlet.Servlet" {}

But I'm pretty sure there is much better tolling for such tasks...

The future of this sort of thing (mapping between $foo in language
$bar and package $baz) is DEP-11. It is currently focussed on mapping
packages to "apps" but is in theory aimed at more general mappings,
allowing one to eventually do things like this:

apt-get install java-class:javax.servlet.Servlet

If you want to host service for searching for classes (and other
things) then the following project may be interesting for you:

http://java-deptools.fedorainfracloud.org/
https://github.com/msimacek/java-deptools

It is a web application where you can search for classes and manifest
headers of all JARs in particular OS version. There are plans to
extend it with other capabilities, such as searching for other things
(eg. pom.xml and pom.properties embedded in JARs) and analysing
dependencies between JAR files and distro packages.

Currently only rpm packages are supported, but it should be fairly
easy to add support for deb. It should even be possible to have a
single instance where you would be able to search in various deb- and
rpm-based distros.

Maybe we could revive this tool. If the source is available somewhere I
can host the service on my server.

I often use sources.debian.net with queries like 'class Foo' or 'package
org.bar' to locate the source package containing a class or a package.
