connection - Jedis Cache implementation without JedisPool/commons-pool2-2.0 -

how implement jedis without jedispool/commons-pool2-2.0 because still using jdk 1.5(commons-pool2-2.0 not support jdk 1.5)

how implement thread-safe connection pooling?

i'm not sure jedis compatibility java 5. can create own pooling based on older commons-pool 1.6 library. not need have commons-pool2 on class path run jedis. used jedis 2.7.3 , commons-pool 1.6 validate solution approach.

find example code attached:

import org.apache.commons.pool.objectpool; import org.apache.commons.pool.poolableobjectfactory; import org.apache.commons.pool.impl.genericobjectpool; import redis.clients.jedis.jedis;  public class jediswithownpooling {      public static void main(string[] args) throws exception {          objectpool<jedis> pool = new genericobjectpool(new jedisfactory("localhost"));          jedis j = pool.borrowobject();         system.out.println(j.ping());          pool.returnobject(j);          pool.close();      }      private static class jedisfactory implements poolableobjectfactory<jedis> {          private string host;          /**          * add fields need. that's example.          */         public jedisfactory(string host) {             this.host = host;         }          @override         public jedis makeobject() throws exception {             return new jedis(host);         }          @override         public void destroyobject(jedis jedis) throws exception {             jedis.close();         }          @override         public boolean validateobject(jedis jedis) {             return jedis.isconnected();         }          @override         public void activateobject(jedis jedis) throws exception {             if (!jedis.isconnected()) {                 jedis.connect();             }         }          @override         public void passivateobject(jedis jedis) throws exception {          }     } }
