Understand that you'll need:

1) A JDK to use to learn and use Java, and also to run Eclipse.

2) Python, which you've downloaded an installed.

3) Your choice of Eclipse IDE (as Nitin points out).

4) Last, after launching Eclipse, go to Help -> Eclipse Marketplace,
search for and download PyDev. When you configure PyDev, you'll be
telling it where to get Python from.

PyDev isn't supported by these Eclipse forums. You'll do better at
stackoverflow.com for problems arising using PyDev.

You may or may not find these notes useful:

You don't want to rename workspaces and projects willy-nilly. There are
metadata in files such as .metadata, .project, .classname, .settings,
etc. that record locations and names.

The easiest thing to do is to set up a new workspace, launch Eclipse,
select that workspace, import any projects you've started on, then
discard the old workspace.

In the face of this advice, beware what you do with the projects. If
you've created them inside the old, broken workspace, you'll want to
understand how Eclipse works a little better before discarding your
workspace unless you also elect to bring a copy of those projects into
the new workspace. If you let Eclipse copy the project into your new
workspace, you're safe deleting the old workspace including what was in
the projects.

In future, manage workspaces and project from within Eclipse rather than
from the filesystem until you gain a better understanding of what's
going on.

Cheers and best of luck.

(Sorry for any confusion in my last post, I meant to type .classpath.)

Hello,

After you install and start your bundle, did you refresh the web UI? It does not do this automatically, so you will need to do this to see your service listed.

Two important notes from the tutorial: 1. You must implement the ConfigurableComponent interface with your class; 2. You must expose your bundle as a service to Declarative Services [1].

If you have done these things, I would need to see parts of your code. Maybe post the relevant parts to Github.

Thanks,
--Dave
