java.lang.NoClassDefFoundError: org/togglz/spring/spi/AbstractSpringBeanFinder

[Jeff Petit]

Hi,

I am brand new to togglz and trying to do a POC for feature flagging.  Implementing in a webservice running on weblogic using spring, so added the following dependencies:

<!-- Togglz dependencies -->
<dependency>
  <groupId>org.togglz</groupId>
  <artifactId>togglz-core</artifactId>
  <version>2.5.0.Final</version>
</dependency>

<dependency>
  <groupId>org.togglz</groupId>
  <artifactId>togglz-spring-web</artifactId>
  <version>2.5.0.Final</version>
</dependency>

Have implemented Feature enum and TogglzConfig:

public enum Features implements Feature {

  TS_1234,

  TS_2345,

  TS_3456;

  public boolean isActive() {

    return FeatureContext.getFeatureManager().isActive(this);

  }

}

_________________________________________________________

@Component

public class FeaturesConfiguration implements TogglzConfig {

  public Class<? extends Feature> getFeatureClass() {

    return Features.class;

  }

  public StateRepository getStateRepository() {

    return new FileBasedStateRepository(new File("/resources/features.properties"));

  }

  public UserProvider getUserProvider() {

    return new ThreadLocalUserProvider();

  }

}

And getting NoClassDefFoundError when calling Feature.isActive().  Don't think I'm missing a dependency, any thought on what I am doing wrong?

Thanks,
Jeff

The "togglz-spring-web" module depends on "togglz-spring-core" which contains this class. could you check if this dependency is included in your deployment archive?

But this error could also be caused by some packing issue. Are you deploying your app as an EAR archive?
