Example 81 with ComponentLookupException

use of org.xwiki.component.manager.ComponentLookupException in project xwiki-platform by xwiki.

    // This is of course not necessary for XWiki components since they just need to implement
    // the Composable interface to get access to the Component Manager or better they simply
