Java Database Connectivity (JDBC)

I have a script in JAVA in which I am creating around 10 tables .....the condition is that either all should be created or none...so I decided to use transaction. but, I found that for DDL statement JDBC connection.autocommit(false) doesn't work, CREATE statement automatically gets committed.for DML statements it works fine.

import java.sql.*;
class testinORCL{

public static void main(String args[]){

		java.sql.Connection connect = null;
		try{
		
		OracleDataSource ods = new OracleDataSource();
		ods.setURL("jdbc:oracle:thin:xxxx/XXXX@ssssss:1521:XE");
		connect = ods.getConnection();
		connect.setAutoCommit(false);
		Statement statement = connect.createStatement();
		statement.executeQuery("CREATE TABLE TEMP_table (field VARCHAR(20) , value VARCHAR(30)) ");
		connect.rollback(); //the table should not be created
		connect.setAutoCommit(true);
		connect.close();
		
		}catch(Exception e){System.out.println(e);}
	}
}

i also checked these....
DatabaseMetaData.dataDefinitionCausesTransactionCommit() (which is true in my case)
DatabaseMetaData.dataDefinitionIgnoredInTransactions() (which is false in my case)


so if anyone can explain me how should I handle this......
