Dozer org.apache.commons.lang.ClassUtils.getClass(Ljava/lang/String;) error

Question

I'm trying to map two classes using Dozer. But everytime that I enter the method that where is mapping the classes the following error is thrown:

org.apache.commons.lang.ClassUtils.getClass(Ljava/lang/String;)

Someone knows what I'm missing or doing wrong?

I created the dozerBeanMapping.xml in src/main/resources and added the mapping:

 <?xml version="1.0" encoding="UTF-8"?>
    <mappings xmlns="http://dozer.sourceforge.net"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://dozer.sourceforge.net 
http://dozer.sourceforge.net/schema/beanmapping.xsd">
     <mapping>
        <class-a>com.projectx.standard.services.user.model.Address</class-a>
        <class-b>com.projectx.standard.dao.user.model.AddressDTO</class-b>
      </mapping>
    </mappings>

and also added to my pom.xml the following dependencies:

<dependency>
    <groupId>net.sf.dozer</groupId>
    <artifactId>dozer</artifactId>
    <version>5.3.1</version>
</dependency>
<dependency>
    <groupId>org.apache.xmlbeans</groupId>
    <artifactId>xmlbeans</artifactId>
    <version>2.4.0</version>
    <scope>runtime</scope>
</dependency>

And my class that where the mapping is:

public void saveAddress(Address address) {

        Mapper mapperBeanName = DozerBeanMapperSingletonWrapper.getInstance();
        PostalCode postalCode = address.getPostalCode();
        this.postalCodeService.savePostalCode(postalCode);

        address.setFkPostalCode(postalCode.getId());

        AddressDTO addressDTO = mapperBeanName.map(address, AddressDTO.class);
        this.addressServiceDAO.saveAddress(addressDTO);

    }

and the stack trace:

Thank you

I am not sure but sometime faces this issue because the method not exist in the class. — Kick

Do you have an explicit dependency in commons-lang? can you show whole dependencies section in pom? — Ori Dar
– Ori Dar, Commented Jan 26, 2014 at 17:30
yes i have this dependency: <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-lang3</artifactId> <version>3.2.1</version> </dependency> — amachado

It definitely looks like an old commons-lang dependency. You can try to run mvn dependency:tree to see if there is no other jar from this library on a classpath. — Marcin Zajączkowski

Thanks.. I did check... and the problem was indeed old versions of dozer (maybe a version conflit)... now everthing is working!! Btw, it is possible to set the mapper as autowire? — amachado

It definitely looks like an old commons-lang dependency. You can run:

mvn dependency:tree

to see if there is no other jar from this library on a classpath. In case of multiple jars from the same library (for example in different versions) JVM can use wrong classes.
