how to map an array of custom type from postgres to java using hibernate -

i trying map array of custom type returned postgres procedure java

i have custom type in postgres

create type public.customtype_sample as(     sampleid bigint,     samplename character varying,     samplevalue character varying ) 

the procedure returns array of customtype_sample column of type customtype_sample[] in postgres

i went through various link: how map user data type (composite type) hibernate

array usertype in hibernate , postgresql --> mappingexception

and may more wrote class implements array of sampletype end getting exception

"could not execute query"  

caused : org.postgresql.util.psqlexception: method org.postgresql.jdbc4.jdbc4array.getarrayimpl(long,int,map) not yet implemented.

the error occurs in nullsafeget method of usertype

@override     public object nullsafeget(resultset rs, string[] names,             sessionimplementor session, object owner)             throws hibernateexception, sqlexception {         sampletype[] javaarray = null;         array array = (array) rs.getarray(names[0]);          if (!rs.wasnull()) {          javaarray = (sampletype[]) array.getarray();//error occurs here           }          return toreferencetype(javaarray);      } 

seems when trying array of custom type there might problem not able understand how write usertype class array of customtype. appreciated.
