hi,

I am getting this error while logging into my application.

I have 2 tables. Facility and Runway. One FACILITY can have many RUNWAY.

Below is Runway.hbm.xml file:

<hibernate-mapping>
<class name="hdpt.Runway" table="RUNWAY" schema="dbo" catalog="Employ">
<id name="runwayId" type="integer">
<column name="RUNWAY_ID" />
<generator class="assigned" /> //CHANGED TO NATIVE
</id>
<many-to-one name="facility" class="hdpt.Facility" fetch="select" cascade="none" >
<column name="FACILITY_ID" not-null="true" />
</many-to-one>

generator class for Runway is "assigned". I need to add a new record to Runway table and it throws "ids cannot be assigned manually".

So i changed the generator class to "native" in Runway table . When i try to login to application itself after changing the generator class,

it is throwing the below error.

Any suggestions. why is failing to login to application itself after changing the generator class of Runway.
