Access OSGI ser­vice from Sightly WCMUsePojo | AEM 6.3

Create AEM 6.3 component making use of WCMUsePojo accessing OSGI Service.

Step 1: Create an interface name OSGITestInterface.java that will be implemented by service impl.

public interface OSGITestInterface {

String getOSGIName();

String getOSGIDesc();

String getOSGIuse();

String getOSGIData();

}

Step 2: Create a Interface Implementation class name OSGITestInterfaceImpl.java

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.apache.felix.scr.annotations.Component;

import org.apache.felix.scr.annotations.Service;

@Component

@Service

public class OSGITestInterfaceImpl implements OSGITestInterface {

Logger logger = LoggerFactory.getLogger(OSGITestInterfaceImpl.class);

@Override

public String getOSGIName() {

  return "Test Service";

}

@Override

public String getOSGIDesc() {

  return "AEM OSGI Service";

}

@Override

public String getOSGIuse() {

  return "OSGI Service data";

}

        @Override

public String getOSGIData() { 

  String name = this.getOSGIName();

  String desc = this.getOSGIDesc();

  String use = this.getOSGIuse();

  return name + desc + use;

}

}

Step 3: Create Test Component and use below sightly code in component html.

Fetch values from OSGI Service using WCMSUepojo.

    <sly data-sly-use.info="com.test.utils.TestPojoComp"></sly>

    ${info.details}

</div>

Step 4: Write helper class extending WCmUsePojo.

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import com.adobe.cq.sightly.WCMUsePojo;

public class TestPojoComp extends WCMUsePojo {

Logger logger = LoggerFactory.getLogger(TestPojoComp.class);

protected String detail;

@Override

  public void activate() {  

OSGITestInterface service = getSlingScriptHelper().getService(OSGITestInterface.class);

    detail = service.getOSGIData();

  }

  public String getDetails() {

    return this.detail;

  }

}

Step 5: Create webpage using any of existing template. Drag and drop newly created component into the page.

Validate output.
