I'm trying to use hibernate validation, code compiles, but when launched in fails with error:
Exception in thread "main" javax.validation.ValidationException: HV000183: Unable to initialize 'javax.el.ExpressionFactory'. Check that you have the EL dependencies on the classpath, or use ParameterMessageInterpolator instead
Code:
import javax.validation.ConstraintViolation;
import javax.validation.Validation;
import javax.validation.Validator;
import javax.validation.ValidatorFactory;
public class Run {
public static void main(String[] args) {
User u = new User();
ValidatorFactory factory = Validation.buildDefaultValidatorFactory();
Validator v = factory.getValidator();
Set<ConstraintViolation<User>> result = v.validate(u);
System.out.println(result.size());
}
}
User class:
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Pattern;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlType;
public class User {
@Pattern(regexp="[a-zA-Z0-9_]{5,10}", message="Username must be 5 to 10 characters long, " +
"only digits, letters and underscore permitted.")
@XmlAttribute(name = "username", required = true)
protected String username;
@Pattern(regexp="[0-9a-zA-Z]{5,10}", message="Password must be 5 to 10 characters long, " +
"only digits and letters permitted.")
@XmlAttribute(name = "passwd", required = true)
protected String passwd;
@NotNull
@XmlAttribute(name = "authToken", required = true)
protected String authToken;

I following guide at http://hibernate.org/validator/documentation/getting-started/ and use exactly same dependencies, also tried with dependencies in post Running Spring Boot within IntelliJ results in Unable to load 'javax.el.ExpressionFactory' (without any spring boot code, just with spring-boot-starter-tomcat
in dependencies and without deploying to servlet container). Also tried dependencies from book "Beginning Spring":
<dependency>
<groupId>javax.el</groupId>
<artifactId>javax.el-api</artifactId>
<version>3.0.0</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.glassfish</groupId>
<artifactId>javax.el</artifactId>
<version>3.0.0</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.1.0</version>
<scope>provided</scope>
</dependency>
which concerns exactly same error, but it didn't solve the problem.
You have 2 different incompatible versions of javax.el (3 and 2).
Just use this dependency, which will cover everything (it's the one we recommend in the GitHub repo's README.md but I need to update the getting started guide):
<dependency>
<groupId>org.glassfish</groupId>
<artifactId>javax.el</artifactId>
<version>3.0.1-b08</version>
</dependency>
and remove all the other javax.el dependencies (API and impl). It should work like a charm once you're done.
None of the above worked for me However This did: Right click on the project > Properties > Project Facets on the right most area select Runtimes tab and selct your Tomcat Runtime, this will provide the required libs available to the test.
