Problem with @Configuration and CGLIB

[sometimes]

Hello,

I have read tutorials Putting the Spring in Your Step and Getting Started with Spring ....
So i am trying to get examples work.

1. I'm using STS and created new project using Spring MVC Template (as usual pom.xml build file and Spring built-in server).

2. Added cglib-2.2.2.jar to build path (Referenced Libraries).

3. Created file CrmConfiguration.java and written inside:

package cglib.is.bad;
import org.springframework.context.annotation.Configurati on;

@Configuration
public class CrmConfiguration {
}

4. Running server and getting exception:

java.lang.IllegalStateException: CGLIB is required to process @Configuration classes. Either add CGLIB to the classpath or remove the following @Configuration bean definitions: [crmConfiguration]
...

What should i do to get @Configuration work?
Thank you for your answers!

You should use maven to add the dependency and not add it manually to the build path.

You should use maven to add the dependency and not add it manually to the build path.

Thank you for advice, now i've read more about Maven and dependencies, interesting stuff.

Added to pom.xml file following rows:

<dependency>
<groupId>cglib</groupId>
<artifactId>cglib-full</artifactId>
<version>2.0.2</version>
</dependency>

And the exception about CGLIB did not occur anymore.

However a new exception have risen.
Searching for a new solution now.

ERROR: org.springframework.web.servlet.DispatcherServlet - Context initialization failed
java.lang.IllegalStateException: Cannot load configuration class: one.more.spring.CrmConfiguration

For cglib you should use the nodep version (and probably the 2.2 version). Class cannot be loaded either class not found or some error related to dynamic class generation. Enable debug logging for spring and check the spring log files.

Thank you, sometimes, this solved my problem.
