Java Database Connectivity (JDBC)

Hey all, I have created this materialized view for my java to select from. For some reason when I try to select from it, I get invalid column name. Here is my mat view statement in its simplest form:

create materialized view mv_pgridtcevcluster_property as
select distinct clustername_ as "OBJECT_ID", CLUSTERNAME_, LICENSEMODE_
from p_gridtcevcluster p
order by clustername_;


Now when I run my select statement from jdbc:

SQL: select object_id from MV_PGRIDTCEVCLUSTER_PROPERTY
java.sql.SQLException: Invalid column name
at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:112)
at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:146)
at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:208)
at oracle.jdbc.driver.OracleStatement.getColumnIndex(OracleStatement.java:3319)
at oracle.jdbc.driver.OracleResultSetImpl.findColumn(OracleResultSetImpl.java:1926)

at com.mchange.v2.c3p0.impl.NewProxyResultSet.getString(NewProxyResultSet.java:3342)
at historian.objects.mgmt.udrManagerTest.gatherObjects(udrManagerTest.java:73)

Anyone have issues with this before? It seems to throw the error sporatically, any help would be much appreciated!

Nevermind, figured it out. Was using wrong column name identifier when picking values from resultset.
