AbstractMethodError on deploying Spring 4.0 in Tomcat 6 - spring

Question

I am getting below exception on deploying Spring 4.0.1 app in Tomcat 6.0.37:
SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.validation.beanvalidation.OptionalValidatorFactoryBean#0': Invocation of init method failed; nested exception is java.lang.AbstractMethodError: org.hibernate.validator.internal.engine.ConfigurationImpl.getDefaultParameterNameProvider()Ljavax/validation/ParameterNameProvider;

Is the error because of spring-beans and spring-webmvc depends on EL 2.2.4 version whereas Tomcat 6 comes with EL 2.1. If so, how to resolve it? Also, I do not have rights to update libs in Tomcat dir.

Answer 1

The error has nothing to do with the EL. It has all to do with the javax.validation api and hibernate.
java.lang.AbstractMethodError: org.hibernate.validator.internal.engine.ConfigurationImpl.getDefaultParameterNameProvider()Ljavax/validation/ParameterNameProvider
Hibernate validator 4.3.x is an implementation of javax.validation 1.0 (JSR-303). However you are including the 1.1 API version. Either downgrade the included javax.validation version or upgrade your hibernate validator to 5.0.x.

Answer 2

Check to see if there are multiple references to validator in your pom file
<?xml version="1.0" encoding="UTF-8"?>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>${hibernate-val.version}</version>
</dependency>
