Domino OSGI plugin - Couldn't find design note

I am trying to creata a Domino OSGI plugin which exposes a simple Hello World servlet. To do this I created in eclipse a plugin project(with web.xml and the servlet in place) , a feature project containing this plugin and an updated site project.

After this I created an application in Domino designer using the 'Eclipse Update Site' as template (name RestDemoUpdateSite.nsf). With this application open in Domino administrator, I successfully imported my eclipse update site.

Finally I copied RestDemoUpdateSite.nsf to the folder - C:\Program Files\IBM\Domino\data and added the line OSGI_HTTP_DYNAMIC_BUNDLES=RestDemoUpdateSite.nsf in notes.ini.

The link http://<>/RestDemoUpdateSite.nsf opens fine

A GET request to http://<>/RestDemoUpdateSite.nsf/api/ gives the json response

{
  "services":[
    {
      "name":"Data",
      "enabled":false,
      "version":"9.0.1",
      "href":"\/RestDemoUpdateSite.nsf\/api\/data"
    },
    {
      "name":"Calendar",
      "enabled":false,
      "version":"9.0.1",
      "href":"\/RestDemoUpdateSite.nsf\/api\/calendar"
    },
    {
      "name":"Core",
      "enabled":true,
      "version":"9.0.1",
      "href":"\/RestDemoUpdateSite.nsf\/api\/core"
    }
  ]
}

A GET request to my servlet http://<>/RestDemoUpdateSite.nsf/serviceapi/student gives the error

HTTP Web Server: Couldn't find design note - serviceapi/student [/RestDemoUpdateSite.nsf/serviceapi/student] Anonymous

Any suggestion or hints as to what might be going wrong would be of great help.

Thank you

Solution

  • The first step is to make sure your plugin is being loaded by the OSGi framework. Execute the following server console command:

    tell http osgi ss {bundle.name}

    For example, tell http osgi ss com.ibm.domino.services lists all the plugins matching the given name. The listing tells you whether a plugin is ACTIVE, RESOLVED, INSTALLED, etc.

    Assuming your plugin is being loaded, the next step is to make sure you are defining your servlet correctly. You said you included a web.xml file, but OSGi servlets are typically defined in plugin.xml. They implement the org.eclipse.equinox.http.registry.servlets extension. You can find more details in these slides. See the section starting with "Creating, deploying & debugging a simple servlet".
