Question

I am new to Spring programming and currently struggling with Spring 3.1’s Java Based Configuraion” I have created following Configuration class

@Configuration
@ImportResource("classpath:/resources/jdbc.properties")
public class AppConfig {

    @Autowired
    Environment env;
    private @Value("${jdbc.url}")
    String url;
    private @Value("${jdbc.username}")
    String username;
    private @Value("${jdbc.password}")
    String password;

    @Bean
    public DataSource dataSource() {
        System.out.println("Creating data Source.");
        return new DriverManagerDataSource(url, username, password);
    }

    @Bean
    public SessionFactory sessionFactory () throws Exception {
        return new AnnotationSessionFactoryBuilder().setDataSource(dataSource()).setPackagesToScan("com.argusoft.loginmodule.domain").buildSessionFactory();
    }
}

now when I try to run the project I get following error.

OUTPUT

SEVERE: Exception while loading the app :
java.lang.IllegalStateException: ContainerBase.addChild: start:
org.apache.catalina.LifecycleException:
java.lang.IllegalArgumentException: javax.servlet.ServletException:
java.lang.NoClassDefFoundError:
org/springframework/core/env/EnvironmentCapable

stuck into it, Cant solve it….. I am following Spring Source Blog.

please also suggest some good tutorial in which Spring’s latest Java based configuration is explained by easy to understand examples…

Thanks in advance,

Answer 1

From the perspective of the exception:

java.lang.NoClassDefFoundError: org/springframework/core/env/EnvironmentCapable

This question is equals to the question: Spring class EnvironmentCapable

So the correct answer might be:

I think that need use version 3.1.0 – in package
org.springframework.core-3.1.0.M2.jar this class presents.
