Intellij IDEA 12.1.6 - hibernate doesn't resolve table or column name

I'm writing my first webapp on IDEA. I'm having a small problem with model classes. IDE can't resolve a names of tables, columns, attributes, ect. from a database and marks this as errors. I DO have a Data Source configured (even on IDE scope). Do anybody know how to bypass that (while having a working project of course :))? As in title, I'm using an IntelliJ IDEA 12.1.6 version.
