Unable to instantiate default tuplizer [org.hibernate.tuple.entity.PojoEntityTuplizer]

Question

I am developing an application with Hibernate and I get an Exception when I connect with database. The exception is:

Unable to instantiate default tuplizer [org.hibernate.tuple.entity.PojoEntityTuplizer] 

My mapping file is:

<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> 

And the class with getters/setters which are not included:

public class SetPoint {     private int iSetPointId;     private String sSensorType;     private double dValue;     private String sRelationship;     private int iDeviceId; } 

I have javassist.jar included into classpath. I do not know what is the problem. Someone would help me please.

Thanks!

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?

Answer 1

I was also facing the same issue.

Added the same dependency and it worked (like this):

<dependency>     <groupId>javassist</groupId>     <artifactId>javassist</artifactId>     <version>3.12.1.GA</version> </dependency>
