Change field name in Jasper

2

I am putting together a report and as I work with more than one table, there are the same field names. JasperStudio started adding fields giving names like: COLUMN_1, COLUMN_2, etc.

My question is: Can you change these names without being placed in description ? When I change and try to run the report, it returns the error:

  

net.sf.jasperreports.engine.JRException: net.sf.jasperreports.engine.JRException: Unknown column name project_id in result set.
