clear jboss cache using java code -


i want clear jboss cache using java code , goal i'im implement following code:

public void clearcache(string s){         string[] st=cachemanager.getinstance().getcachenames();         cache cache =cachemanager.getinstance().getcache(s);          cache.flush();     }

is code correct? , how can sure jboss cache cleared successfully? thank you

you have 3 bugs in code. first, don't need query getcachenames(); you're passing in name of cache you're wanting clear, , you're throwing away results in st. next, there's no such method cachemanager#getcache(string); it's getcache(string, boolean) throws exception, , need passing s, false , handling (far broad exception). finally, never check whether cache exists; if passes in name representing nonexistent cache, cache null, , you'll npe when try flush() it.
