java - Load a class with all it's components from outter jar -

i have code:

    // getting jar url contains target class     url[] classloaderurls = new url[]{new url("linktojar")};      // create new urlclassloader      urlclassloader urlclassloader = new urlclassloader(classloaderurls);      // load target class     class<?> beanclass = urlclassloader.loadclass("com.my.class");      // create new instance loaded class     constructor<?> constructor = beanclass.getconstructor();     object beanobj = constructor.newinstance();      // getting method loaded class , invoke     method method = beanclass.getmethod("sayhello");     method.invoke(beanobj); 

it's supposed call sayhello method needs 1 bean work.

the method prints "hello %name", name @autowired string.

the call method working, problem it's saying "hello" because string not being autowired, , it's "null".

how can make autowired possible, if context in jar i'm calling , seems not being load??

thanks.

edit::

the idea have like:

applicationcontext context = new classpathxmlapplicationcontext(         "classpath*:**/applicationcontext*.xml");  myadder myadder = (myadder) context.getbean("myadder"); 

in order load context, don't know how load context outter jar.

how expect work, spring has no idea external classes - out of application context. injecting indeed looks "magic" done spring container.

you have use own application context, , bean "the spring way".

http://docs.spring.io/spring/docs/current/spring-framework-reference/html/beans.html

one way around inject required string current context, , pass argument method.

another, more "inject style" method, set string using reflection - more or less how done spring container internally.
