To access the properties from an OSGi configuration in a WCMUse class in AEM 6.1, you can follow these steps:

1. Define the OSGi configuration that contains the properties you want to access. This can be done by creating a configuration interface and annotating it with the @Designate annotation.

Here is an example of an OSGi configuration interface:

```html

        
            <code>package com.example.configuration;

            import org.osgi.service.metatype.annotations.ObjectClassDefinition;

            @ObjectClassDefinition(name = "Sample Configuration", description = "This is a sample OSGi configuration")
            public @interface SampleConfiguration {

            String sampleProperty() default "defaultValue";

            }</code>

```

2. Inject the configuration values into the WCMUse class using the @Reference annotation. This annotation allows you to reference OSGi services such as configurations.

Here is an example of how you can inject the OSGi configuration into a WCMUse class:

```html

        
            <code>package com.example.core.models;

            import com.example.configuration.SampleConfiguration;
            import org.apache.sling.api.SlingHttpServletRequest;
            import org.apache.sling.api.resource.Resource;
            import org.apache.sling.api.wrappers.ValueMapDecorator;
            import org.apache.sling.models.annotations.Model;
            import org.apache.sling.models.annotations.injectorspecific.ValueMapValue;

            import javax.inject.Inject;
            import org.osgi.service.component.annotations.Reference;

            @Model(adaptables = {SlingHttpServletRequest.class, Resource.class})
            public class SampleModel {

            @Inject
            private SampleConfiguration sampleConfiguration;

            @ValueMapValue
            private String pageTitle;

            public String getTitle() {
            return pageTitle + " - " + sampleConfiguration.sampleProperty();
            }

            }</code>

```

By following these steps, you can access properties from an OSGi configuration in a WCMUse class in AEM 6.1.
