I am developing an application with Hibernate and I get an Exception when I connect with database. The exception is: <pre><code>Unable to instantiate default tuplizer [org.hibernate.tuple.entity.PojoEntityTuplizer] </code></pre> My mapping file is: <pre><code><hibernate-mapping> <class name="com.cartif.database.SetPoint" table="SetPoint"> <id name="iSetPointId" column="setpointid" type="java.lang.Integer"> <generator class="sequence"> <param name="sequence">s_setpoint</param> </generator> </id> <property column="sensorType" generated="never" lazy="false" name="sSensortype" type="java.lang.String"/> <property column="value" generated="never" lazy="false" name="dValue" type="java.lang.Double"/> <property column="relationship" generated="never" lazy="false" name="sRelation" type="java.lang.String"/> <property column="deviceid" generated="never" lazy="false" name="iDeviceId" type="java.lang.Integer"/> </class> </hibernate-mapping> </code></pre> And the class with getters/setters which are not included: <pre><code>public class SetPoint { private int iSetPointId; private String sSensorType; private double dValue; private String sRelationship; private int iDeviceId; } </code></pre> I have javassist.jar included into classpath. I do not know what is the problem. Someone would help me please. Thanks! <hr> I found when the error is launched. If I include properties in mapping file exception is thrown. If I only declare id of table, the exception is not thrown. What is the possible cause? <hr> The complete stacktrace is: <pre><code>162980 [btpool0-2 - /Gateway/zigbeedriver/app] ERROR org.hibernate.proxy.pojo.BasicLazyInitializer - Javassist Enhancement

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
