insert daterange field value

Hello!

I have a table in PostgreSQL(9.3) with daterange field type.

I can select this field like a String with JDBC, but I cannot Insert it in a table.

What I've tried:

PreparedStatement stm = conn.prepareStatement("insert into mytable (my_daterange_field) values (?)"); 
stm.setString(1, "[2014-01-02,2014-01-04]");
int i = stm.executeUpdate();

and I got:

Exception in thread "main" org.postgresql.util.PSQLException: ERROR: column "my_daterange_field" is of type daterange but expression is of type character varying Hint: You will need to rewrite or cast the expression. Position: 168

Does anyone have a solution for inserting daterange? What stm.setXXX should I use? Or maybe I cannot do that because JDBC Driver does not have daterange support... Maybe there is a third solution?

Thank you.

P.S.

My PostgreSQL JDBC Driver:

    <dependency>     <groupId>postgresql</groupId>     <artifactId>postgresql</artifactId>     <version>8.4-701.jdbc4</version>   </dependency>
