Before you dive into OSGi development, you'll need a proper development environment, and that usually means Eclipse. Domino Designer, being Eclipse-based, can technically do the job and has the advantage of some of the setup being done, but it's so out-of-date at this point that it's not worth it (believe me, I tried originally). Newer Eclipse versions have improved noticeably, so it's best to grab a recent version. Currently, that means Mars, or Eclipse 4.5.1.
Before Eclipse, you'll need to install Java if you haven't already. To do that, go to Oracle's site and download the latest release for your platform. Once you install it and find out how many devices run Java, you can move on to installing Eclipse.
Head to the Eclipse download page and download the "Eclipse IDE for Java EE Developers" for your platform. They've recently added an Installer at the top of the page, and that works as well, but adds some new wrinkles that haven't made it into common knowledge yet. For now, you may want to stick with the "...or download an Eclipse Package" section. The "bitness" (32 or 64) doesn't matter too much - you should generally match the bitness of your OS.
Once you have Eclipse installed and running ("installation" generally involves dragging the extracted ZIP file content somewhere), the next step is to teach Eclipse about the XPages artifacts. If you're running on Windows and have a local Domino server, the XPages SDK may be your friend, though it hasn't been fully tested for Mars. If you are running on a non-Windows OS or otherwise don't want to go the full SDK route, there's a quick route that lacks the automation and debugger integration.
Setting up the environment used to be something of a hassle, but it became much simpler ever since IBM released the Update Site for Build Management. Primarily made for Maven-development use (sort of), this Update Site also serves as a quick stop to pick up all of the dependencies you need for XPages development in one place.
To make use of the Update Site, download the file from OpenNTF, extract it, and then extract the
UpdateSite.zip file contained therein. You should end up with a folder like this:
In Eclipse, go to the preferences ("Window" → "Preferences" on Windows or "Eclipse" → "Preferences" on a Mac), then go to "Plug-in Development" → "Target Platform":
Edit the existing platform and, in the "Locations" tab of the ensuing dialog, click "Add..." → "Directory" → "Next", browse to that extracted UpdateSite folder, and click "Next" to verify that it finds a bunch of plugins, and then "Finish". Now, you'll be able to reference XPages platform plugins in your projects.
At this point, Eclipse is set up for the essentials, but it may still be a good idea to set up an appropriate JVM for Domino development to make sure you have a consistent baseline and to avoid problems where newer Java releases added classes methods not avilable in Java 6. Fortunately, on Windows (and Linux?), a Notes installation comes with a JVM that does the job nicely. To add it, go back to preferences, then "Java" → "Installed JREs" → "Add...". Choose "Standard VM" → "Next", browse to the "jvm" folder in your Notes (or Domino) installation directory, name it something appropriate, and then click Finish:
On the Mac, you can get a similar Java release from Apple, which nowadays will end up in
/Library/Java/JavaVirtualMachines (older installers put it in
Now that Eclipse is set up, the next step will be to break ground on making an actual XPages plugin.
