Re: [wildfly-dev] Invalid use of BasicClientConnManager for JAX-RS Client API

Hi, This is becuase AppacheHTTPClient will not allow to use the same connection if the previous request is not yet consumed. For eg, as mentioned in the Test (quoted below) @Test public void test1PostAndGet() { MultivaluedHashMap<String, String> map = new MultivaluedHashMap<>(); map.add("name", "Penny"); map.add("age", "1"); target.request().post(Entity.form(map)); map.clear(); map.add("name", "Leonard"); map.add("age", "2"); target.request().post(Entity.form(map)); // <--- Reference [1] map.clear(); map.add("name", "Sheldon"); map.add("age", "3"); target.request().post(Entity.form(map)); <--- Reference [2] Person[] list = target.request().get(Person[].class); assertEquals(3, list.length); assertEquals("Penny", list[0].getName()); assertEquals(1, list[0].getAge()); assertEquals("Leonard", list[1].getName()); assertEquals(2, list[1].getAge()); assertEquals("Sheldon", list[2].getName()); assertEquals(3, list[2].getAge()); } As you can see in *Reference[1]*, the request is made and its response is not consumed. So the connection is still in active state. You should consume the response or call connection.close() before making the second request as mentioned in *Reference[2]*. This is because the "target" object uses the same ApacheHttpClient connection manager which internally uses " SingleClientConnManager" as discussed in the documentation[3].
