Hi,
my program has customer and login tables having one-to-one relationship using many-to-one and unique

I am getting error while running the code
loginmanager=(LoginManager)ctx.getBean("loginManager");


Hibernate mapping

<hibernate-mapping>
<class name="fl_java.com.portfolio.model.Customers" table="CUSTOMERS" schema="">
<id name="customerid" type="java.lang.Long">
<column name="CUSTOMERID" length="10" />
<generator class="increment" />
</id>
<property name="title" type="string">
<column name="TITLE" length="4" not-null="true" />
</property>
<property name="firstname" type="string">
<column name="FIRSTNAME" length="30" not-null="true" />
</property>
</class>
</hibernate-mapping>

<hibernate-mapping>
<class name="fl_java.com.portfolio.model.Login" table="LOGIN" schema="">
<id name="loginid" type="string">
<column name="LOGINID" length="20" />
<generator class="assigned" />
</id>
<many-to-one name="customers" class="fl_java.com.portfolio.model.Customers" fetch="select">
<column name="CUSTID" length="10" not-null="true" unique="true"/>
</many-to-one>
<property name="password" type="string">
<column name="PASSWORD" length="20" not-null="true" />
</property>
</class>
</hibernate-mapping>

Class

public class Customers implements java.io.Serializable {

this is not a problem with Hibernate. If anything it is a problem with Spring. From the code samples, you provide, there is some inconsistency.

You are casting to "LoginManager", but the only class I see, is "LoginManagerI" I do not see a "LoginManager" interface or an implements declaration in LoginManagerI
