Appendix B. Adding JVM packages the system bundle, by default, does not export

Sometimes you might need to add additional JVM packages to a fabric container that are not, by default, configured for export by the system bundle. In a fabric environment, you do not modify the container's jre.properties file directly to achieve this. Instead, you modify the jre.properties indirectly through the container's io.fabric8.agent.properties file.
As the org.osgi.framework.system.packages.extra property in the io.fabric8.agent.properties file is used to augment the list of packages exported from the system bundle, you modify it to add any additional JVM packages that the container requires.

Procedure

This procedure creates a new profile to add, for example, the packages, com.sun.jndi.ldap and com.sun.org.apache.xerces.internal.parsers, to a single fabric container.
Note
If you want to add the same additional packages to all containers in a fabric, follow these steps, but use the default profile, instead of creating a new profile.
  1. Log into the Hawtio Console, and click the Wiki tab.
  2. On the Wiki page, select the Create option.
  3. In the Create dialog, select the Fabric8 profile option, and enter a name for the new profile.
  4. Click Save.
  5. From the profile you just created, select the io.fabric8.agent.properties file.
  6. Click Edit, and add the following line to the file:
    config.org.osgi.framework.system.packages.extra = \
    com.sun.jndi.ldap, \
    com.sun.org.apache.xerces.internal.parsers
    Important
    If the org.osgi.framework.system.packages.extra property already exists, copy in its existing content and then append the additional packages to it.
  7. Click Save.
  8. Add the profile to the container.
