Hibernate error while reading database column (Reverse Engineering)

Question

When I try to reverse-engineer Hibernate, he can’t read the comic book columns. Give this error "Reading Schema Error: Error while Reading column meta data for curso"

Does anyone have any idea what it is? Apparently he’s going into the bank because he’s naming the column...

This is my Hibernate.cfg

    <?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
                                         "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
 <session-factory name="">
  <property name="hibernate.connection.driver_class">org.postgresql.Driver</property>
  <property name="hibernate.connection.url">jdbc:postgresql://localhost:5432/cursojava</property>
  <property name="hibernate.connection.username">postgres</property>
  <property name="hibernate.connection.password">******</property>
  <property name="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</property>
 </session-factory>
</hibernate-configuration>

Thank you in advance!
