java - HBase connection pool in Tomcat? -

i have small hbase cluster running java frontend. have working test code establishes connection, runs test data, , disconnects, need extend webapp part of larger project. suggested use tomcat http service interface database, , part of need set connection pool.

i understand connection pools on conceptual level (a pile of persistent connections db handed out clients needed , returned pool when discarded), i've never written webapp before , tomcat vexxing me. can find loads of documentation on how setup connection pool sql server using jdbc, nothing on hbase (or, matter, sql) , nothing on how (or whether can or should) write custom interface working tomcat. doable, or possible, or should taking different approach?

i think hard find made tomcat, don't think such thing exist. people using custom classes. being said, should build around htablepool comes hbase.

here example of can use in project :

public class htablemanager {      public static int htable_pool_size = 15;      private static htablemanager instance;     private static htablepool htablepool;      /**      * private constructor      */     private htablemanager() {         try {             configuration config = hbaseconfiguration.create();             config.set("hbase.defaults.for.version.skip", "false");              htablepool = new htablepool(config, htable_pool_size);         } catch (ioexception ex) {             // error handling         }     }      /**      * @return hbasetablemanager instance      */     public static htablemanager getinstance() {         if (instance == null) {             instance = new htablemanager();         }         return instance;     }      /**      * method used retrieve htable instance.      *       * @param tablename table name      * @return htableinterface instance      * @throws ioexception       */     public synchronized htableinterface gethtable(string tablename) throws ioexception {         return htablepool.gettable(tablename);     } } 

and can use :

htablemanager htablemanager = htablemanager.getinstance(); htableinterface htable = htablemanager.gethtable("yourtablename"); ... // work htable instance ... // call close method returns pool htable.close();
