Hi all,
I am trying to implement OSGI URL scheme support for JNDI following the
OSGI service specification[1]. While implementing the OSGI URL scheme I
encountered following issues.
As per the specification, Following are the confusions I have:
1. A lookup with osgi:service path will return a service while a
servicelist path returns an context object. Does a query
"osgi:servicelist/" is valid? Or is it mandatory to have a query followed
by the osgi:servicelist/ ?
2. As per the specification, listBindings() and list() methods will
return NamingEnumeration objects. Do both "service" and "servicelist" paths
need to support aforementioned methods?
1. context.list("osgi:service/<qname>") is this a valid URL ?
2. context.list(osgi:servicelist/<qname>) is this a valid URL ?
1. If this is a valid scenario, does the Context object need to
obtain first before doing list() and listbinding() queries?
(Please find a
sample code below)
2.
Context context = jndiContextManager.newInitialContext();
Context listContext =
context.lookup("osgi:servicelist/org.my.jndi.osgi.services.FooService")
NamingEnumeration<NameClassPair> namingEnumeration =
listContext.list("osgi:service/org.wso2.carbon.jndi.osgi.services.FooService");
3.
In a scenario as above, is it valid to pass two different
names to list() and lookup() methods (i.e
context.lookup("osgi:servicelist/SERVICE-A") and do a
context.list(osgi:servicelist/SERVICE-B)) ?
3. As per the specification we mainly support list(),
listbindings(), and lookup() methods. Can we consider the other methods
such as bind(), rebind() , unbind() , rename() as operations that are not
supported with the provider?
Appreciate any input on above queries.
