Hi @vainavee 

Use @inject to adopt the service. Then inside init method call that particular method of that service by passing required inputs from slingmodel. Once you get the data back from service store it in a variable. Create getter of that particular variable. In sightly using use object read the variable.

@Inject
private <Service> service;

private String test = null;

 

@PostConstruct
protected void init() {

test = this.service.<Method>(<required Param>);
}

public void getTest(){

return test;

}

-----------------
Sightly : 
<div data-sly-use.cmp="<slingmodel path>">
<h1> Var : ${cmp.test} </h1>
</div>

    Hi @vainavee ,

     

    You can inject the osgi service in your model class and then invoke the method from the service by passing params.

     

    @Inject
    private MyService myService;

     

    @PostConstruct
    protected void init() {

    String firstName = this.myService.getName(param);
    }

     

    Refer this for more annotations and details.
