Bean Creation Exception with Spring OXM and JAXB2

[Lucky J Verma]

Hi all
This is my first experience with Spring OXM and JAXB 2. (Jdk 5, Tomcat 6) Now i have been trying for few hours to make it work but its not at all .
I keep getting 'Bean Creation Exception' with jaxb2Marshaller Bean .
Someone please help me what is going on.
1. I have spring-oxm-3.0, jaxb-api 2.2 ,jaxb-impl 2.2 api and tools.jar (some forums suggested) added.
2. Annotated Class -Person ( to persist) and Marshaller class OxMapper
3. Now in applicationcontext.xml - i added namespace on top and

<jee:jndi-lookup id="dataSource" jndi-name="jdbc/my_datasource" />
<bean id="oxMapper" class="com.oxm.beans.pojo.OxMapper">

 
        <property name="marshaller" ref="jaxb2Marshaller" />

 
        <property name="unmarshaller" ref="jaxb2Marshaller" />

 
    </bean>

	<oxm:jaxb2-marshaller id="jaxb2Marshaller" >

 
        <oxm:class-to-be-bound name="com.oxm.beans.Person" />

 
    </oxm:jaxb2-marshaller>	

Error i get is ---------

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'oxMapper' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Cannot resolve reference to bean 'jaxb2Marshaller' while setting bean property 'marshaller'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jaxb2Marshaller': Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: javax/activation/DataSource

I tried so many variations like creation of marshaller bean using <bean> tag. But nothing helps.
Please somebody help me.

your configuration looks fine to me but in log you are getting class not found exception. It seems that some jars are missing. I would suggest to use maven for building project.

Hi

Just another question -
Could it e my bean class /entity class wrongly annotated leading to same BeanCreationException.
My entity is

import java.util.ArrayList;
import java.util.List;

import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
@XmlRootElement
public class Person {

	List<Person> personsList = new ArrayList<Person>();

	public List<Person> getPerson() {
		return personsList;
	}

	@XmlElement
	public void setPerson(List<Person> personsList) {
		this.personsList = personsList;
	}

	String name;

	public String getName() {
		return name;
	}

	@XmlElement
	public void setName(String name) {
		this.name = name;
	}

	public String getDivision() {
		return division;
	}

	@XmlElement
	public void setDivision(String division) {
		this.division = division;
	}

	public String getEmail() {
		return email;
	}

	@XmlElement
	public void setEmail(String email) {
		this.email = email;
	}

	String division;
	String email;

	@Override
	public String toString() {
		return getName();
	}

}


Thanks

I usually annotate the getters not the setters, but like was already said that is not your problem. You are missing dependencies on the classpath. You have a ClassNotFound exception.
