Playorm java.lang.Integer cannot be cast to java.math.BigInteger -


i tried construct basic ad hoc query example based on a basic ad hoc query example .

but, can't insert integer value. think because of piece of code:

private class getstoragetypeasclass() {     switch (getstoragetype())     {         case string:             return string.class;         case integer:             return biginteger.class;     } }

my code:

package playorm;  import java.util.hashmap; import java.util.iterator; import java.util.map; import java.util.uuid;  import com.alvazan.orm.api.base.bootstrap; import com.alvazan.orm.api.base.dbtypeenum; import com.alvazan.orm.api.base.nosqlentitymanager; import com.alvazan.orm.api.base.nosqlentitymanagerfactory; import com.alvazan.orm.api.z3api.nosqltypedsession; import com.alvazan.orm.api.z8spi.keyvalue; import com.alvazan.orm.api.z8spi.meta.dbocolumncommonmeta; import com.alvazan.orm.api.z8spi.meta.dbocolumnidmeta; import com.alvazan.orm.api.z8spi.meta.dbodatabasemeta; import com.alvazan.orm.api.z8spi.meta.dbotablemeta; import com.alvazan.orm.api.z8spi.meta.typedcolumn; import com.alvazan.orm.api.z8spi.meta.typedrow;  public class playorm {     private static nosqlentitymanager mgr;      @suppresswarnings({ "unchecked", "rawtypes" })     public static void main(string[] args) {          map properties = new hashmap();         properties.put(bootstrap.auto_create_key, "create");          string clustername = "test cluster";         string seeds = "localhost:9160";         string keyspace = "nosql";          bootstrap.createandaddbestcassandraconfiguration(properties, clustername, keyspace, seeds);         nosqlentitymanagerfactory factory = bootstrap.create(dbtypeenum.cassandra, properties,null,null);         mgr = factory.createentitymanager();         dbodatabasemeta metadb = mgr.find(dbodatabasemeta.class,                 dbodatabasemeta.meta_db_rowkey);         dbotablemeta meta = new dbotablemeta();         meta.setup(null, "myentity", false);         metadb.addmetaclassdbo(meta);          dbocolumnidmeta idmeta = new dbocolumnidmeta();         idmeta.setup(meta, "idfield", string.class, true);         mgr.put(idmeta);          dbocolumncommonmeta fielddbo = new dbocolumncommonmeta();         fielddbo.setup(meta, "firstname", string.class, true, false);         mgr.put(fielddbo);         dbocolumncommonmeta fielddbo2 = new dbocolumncommonmeta();         fielddbo2.setup(meta, "lastname", integer.class, true, false);         mgr.put(fielddbo2);          mgr.put(meta);         mgr.flush();          nosqltypedsession session = mgr.gettypedsession();         (int = 0; < 10000; i++) {             typedrow typedrow = session.createtypedrow("myentity");             typedrow.addcolumn("firstname", "harry");                         //**the problem**             typedrow.addcolumn("lastname", new integer(i));             typedrow.setrowkey(uuid.randomuuid().tostring());              session.put("myentity", typedrow);              if(i > 1000 && (i % 10) == 0 ){                 session.flush();                 mgr.clear();             }          }         session.flush();  }

there no option return integer.class. so, can't construct integer converter:

typedrow special api , allows biginteger, bigdecimal , string types right now.....these types when stored stored lowest bytes possible int value of 10 stored 1 byte.

out of curiosity, why not use myentity.java class annotated @nosqlentity instead??? in case, using pojo seem more beneficial.

myentity.java can have primitive types, int, double, etc. etc.

we thought using entities use entities make development faster.

later, dean
