@Reference Annotation not working in aem Fiddle Script for JSP and servlets

Avatar

Level 1

It complains 

Compilation errors in /apps/acs-tools/components/aemfiddle/fiddle/fiddle.java: Line 15, column 396 : Only a type can be imported. org.osgi.service.component.annotations.Reference resolves to a package

 

Found out one solution and gets the work done:

getService(MyService.class);

 

static <T> T getService(Class<T> serviceClass) {
BundleContext bContext = FrameworkUtil.getBundle(serviceClass).getBundleContext();
ServiceReference sr = bContext.getServiceReference(serviceClass.getName());
return serviceClass.cast(bContext.getService(sr));
}

 

Any better way to do it?

Hi, 


You can use it from slingBinding instead:

 

public class fiddle extends SlingAllMethodsServlet {
    //Any OSGI service you will normally use through 
    MyService service = null; 
    SlingScriptHelper scriptHelper = null;
    
    protected void doGet(SlingHttpServletRequest request, SlingHttpServletResponse response) throws IOException {

        SlingBindings bindings = (SlingBindings) request.getAttribute(SlingBindings.class.getName());
        scriptHelper = bindings.getSling();
        //Here you get the OSGI service
        service = scriptHelper.getService(MyService.class);

 


Hope this helps.

Thanks @EstebanBustamante  That works as well. Seems it depends on the usecase and need. Both solutions with BundleContext and SlingBindings would work.

@antarikshruhil9 There is some issue I am seeing with the fiddle as it is not compiling imports. Removing some keywords from import package also not giving any exception/error. That's because it is not able to resolve any Java file.
