Problem
On OpenIDM startup the Felix Web Console logs the following message:
The root cause is that the distribution does not ship any bundle exporting the
org.osgi.service.prefspackage (OSGi Preferences Service API), which is required by the built-inPreferencesConfigurationPrinterinorg.apache.felix.webconsole. As a result, that section of the Web Console stays disabled.Fix
Add the Apache Felix Preferences bundle (
org.apache.felix:org.apache.felix.prefs:1.1.0), which:org.osgi:org.osgi.service.prefs, which exports theorg.osgi.service.prefspackage (including theBackingStoreExceptionclass).With this bundle in place,
PreferencesConfigurationPrinteris properly enabled in the Felix Web Console.Changes
pom.xml— added dependency management entry fororg.apache.felix:org.apache.felix.prefs:1.1.0.openidm-zip/pom.xml— added the dependency so the bundle is packaged into theopenidm/bundledirectory of the distribution.Verification
mvn -pl openidm-zip -am -DskipTests packagecompletes successfully. The resulting ZIP now contains the required bundles:After starting OpenIDM, the
PreferencesConfigurationPrinter not enabled ... BackingStoreException missingmessage no longer appears in the logs.
