使用hibernate-validator时出现NoClassDefFoundError

Question

I have a mavenized project, where I use JSR 303 (Bean validation). As reference implementation I use Hibernate-validator. In project I specified dependency:

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-validator</artifactId>
    <version>4.1.0.Final</version>
    <scope>provided</scope>
</dependency>

With version 4.1.0 all works fine. But when I change it to 4.2.0. I get runtime error on this line:

ValidatorFactory factory = Validation.buildDefaultValidatorFactory();

java.lang.ClassFormatError: Absent Code attribute in method that is not native or abstract in class file javax/persistence/Persistence

......//more stack-trace

java.lang.NoClassDefFoundError: Could not initialize class com.andr.myproject.services.utils.ValidationUtils

Where is problem?

UPD: Also I use Java-ee-5 dependency , not 6.

UPD2: this error occurs in JUnit test

Answer 1

Do you happen to have the following dependency in your project:

<dependency>
    <groupId>javax</groupId>
    <artifactId>javaee-api</artifactId>
    <version>6.0</version>
</dependency>

If so, you should make sure to exclude it from your runtime classpath, as this JAR can only be used for compilation but not at runtime (it's classes are modified so they contain no method implementations). You can use the API JAR provided by JBoss instead:

<dependency>
    <groupId>org.jboss.spec</groupId>
    <artifactId>jboss-javaee-6.0</artifactId>
    <version>1.0.0.Final</version>
    <type>pom</type>
    <scope>provided</scope>
</dependency>

Likely adding Hibernate Core helped because it pulls in the JPA API in a separate JAR. You can find more information here .

确保maven实际上从回购中获取jar，并使用它，并且该jar中存在提到的类。

I found solution:

I need to add hibernate-core dependency. Without it it wouldn't work.

    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-core</artifactId>
        <version>4.0.1.Final</version>
    </dependency>
