hi everybody!
i want to create a modulare application, which is organized into several
plugins (tapestry component libraries). each plugin has it's own pages /
services / interfaces / logic. each plugin in independent from the
other plugin and also the application.
the application does only contain some stylesheets and minimal basic
functions. the plugins are registered as libraries in the application
using the default application specification mechanism.
my problem now is, that i must give the user some possibility to visit
the pages of the different plugins. -> using pagelink. but that logic
has to be dynamic because the application doesn't know which plugins are
enabled(declared in application specification) or not.
my solution to this problem is ....
all plugins have a hivemind - service which implements a
PluginInterface. now extending applicationServlet.constructRegistry to
get hivemind Registry. using the method
Registry.getServiceIds(java.lang.Class pluginInterface) i get all
enabled plugins ... now with Registry.getService(java.lang.String
serviceId, java.lang.Class serviceInterface) i could invoke each
PluginService which is able to told me pages that i could inject -> now
storing information into ASO.
my questions:
* do you know any better solution, because i am not sure if this
is the
best way
* is the only way to get the Hivemind-Registry to extend
ApplicationServlet.constructRegistry ?
thx
