java - How to access the Impl classes of Twitter4J? -

using mongodb, need persist objects twitter4j. twitter4j uses interfaces, implemented in json versions. example:

the api returns status (an interface), , status implemented statusjsonimpl.

i can't save status mongodb, need implement statusjsonimpl.

my issue is, class statusjsonimpl not public (see here) can't use in code. tried download source of twitter4j manually add "public" statusjsonimpl: can do:

status status = twitter.updatestatus(lateststatus);     string statusstringified = twitterobjectfactory.getrawjson(status); statusjsonimpl statusimplemented = (statusjsonimpl) twitterobjectfactory.createuserlist(statusstringified); singletonlaunchdb.getmongo().save(statusimplemented); 

but still java.lang.illegalaccesserror on class statusjsonimpl @ run time.

i see other sa answers users routinely point other users impl classes... how use in code?

your appreciated.

status serializable. recover statusjsonimpl statusstringified can write.

jsonobject json = new jsonobject(statusstringified); status status = new statusjsonimpl(json); 

the code sample statusserializationtest.java

i hope helps.
