java - How do I get the symbolic name of the bundle, which serivce i use? -


i'm implementing journalling service needed map flow of data throughout osgi framework.

each time clientbundle wants use service form bundle first call function journalling bundle goes little this:

journalservice.journal(args); neededservice.neededfunction(args);

i need following things journal service:

  • bundlename of bundle uses service.
  • bundlename of bundle provides service.
  • which service used.
  • which function of service used (probably string)
  • function arguments.

i know how last 2 (i pass arguments journal: string functionname , object[] args). don't know needs passed first 3, least amount of needed arguments.

if have servicereference, can information off of it. believe frameworks, deep down, use servicereferences reference individual services bundles.

http://www.osgi.org/javadoc/r4v43/core/org/osgi/framework/servicereference.html

you can bundle of service referencing. if bundle referencing service b bundle b, instance method servicereference.getbundle bundle b, , current bundlecontext bundle a.

that said, best bet may use referencelisteners (though may not using blueprint). let know when services referenced or dereferenced , contextual data related it. way may use serviceevent, lets listen register/deregister events. apologize if knew this.

http://www.ibm.com/developerworks/xml/library/os-osgiblueprint/index.html#srms

http://www.osgi.org/javadoc/r4v43/core/org/osgi/framework/serviceevent.html

as far tracking individual methods, can proxy references once pulled out of osgi. bundle have reference service b bundle b. bundle gets proxy of service b which, when called, delegates original method , calls journalservice.

php - Calling a template part from a post -

i include iframe within post in wordpress. located inside content of post, meaning cannot in post template file, otherwise either before or after. i'd add facebook plugin within posts: <div id="socialwrap"><div class="fb-like" data-href="http://onlinearizonahomes.info" data-send="true" data-width="450" data-show-faces="true" data-font="arial"></div></div> i thinking of calling template part within post <?php get_template_part( 'social' ); ?> cannot use php within post without plugin (i'd avoid using plugin this). an alternative using javascript create html in post, seems unnecessary use of javascript. what best way add html within wordpress post? you can use shortcode. add functions.php function cudjex_fbshare( $atts, $content = null ) { global $post; $link = get_permalink($post->id); return '<div id="socialwrap...
