Sightly Call to Java Component

Avatar

Level 3

I have a Java Component , want to call that component in html using sightly. I am trying to use the tag   data-sly-use.settings="com.pnc.xxx.Settings" .

It is initiating the new Instance, but not referring the existing component. How can I refer the existing component in sightly?

When you say It is initiating the new Instance,  are you referring to new java object?

I have the same problem but i am trying to call the java class from the local folder. 

-apps (folder)
    -mywebsite (folder)
        -components (folder)
            -contentpage (cq:Component)
            -partials (folder)
                -navbar.html        
                -Menu.java
                -navbar.js

This is my apps structure.

I am trying to call Menu.java from navbar.html but i can`t, when i am trying to call navbar.js is working correctly. What i am doing wrong ?

navbar.html (using navbar.js)

<nav class="navbar navbar-default" data-sly-use.navbar="../partials/navbar.js">
  <div class="container-fluid">
    <!-- Brand and toggle get grouped for better mobile display -->
    <div class="navbar-header">
        <a class="navbar-brand" href="#">${navbar.info.title}</a>
    </div>

    <!-- Collect the nav links, forms, and other content for toggling -->
    <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
        <ul class="nav navbar-nav navbar-right" data-sly-list="${navbar.items}">
        <li class="${item.page.active ? 'active' : ''}">
            <a href="${item.page.vanityUrl}">${item.page.title}</a>
        </li>
      </ul>
    </div><!-- /.navbar-collapse -->
  </div><!-- /.container-fluid -->
</nav>

navbar.html (using Menu.java)

<nav class="navbar navbar-default" data-sly-use.navbar="../partials/Menu">
  <div class="container-fluid">
    <!-- Brand and toggle get grouped for better mobile display -->
    <div class="navbar-header">
        <a class="navbar-brand" href="#">${navbar.lowerCaseTitle}</a>
    </div>


  </div><!-- /.container-fluid -->
</nav>

Menu.java

package apps.mywebsite.contentpage.partials;
import com.adobe.cq.sightly.WCMUse;

public class Menu extends WCMUse {

    private String lowerCaseTitle;

  
    @Override
    public void activate() throws Exception {
        lowerCaseTitle = "Hristo";
    }

    public String getLowerCaseTitle() {
        return lowerCaseTitle;
    }

}

navbar.js

use(function(){
    var info = {},
        items = [],
        basePath = currentPage.getAbsoluteParent(2),
        currentNavPath = currentPage.getAbsoluteParent(3).getPath(),
           pages = basePath.listChildren(new Packages.com.day.cq.wcm.api.PageFilter());

        info.title = currentPage.getAbsoluteParent(1).getTitle();

    var resourceResolver = resource.getResourceResolver();


    while (pages.hasNext()) {
        var page = pages.next();
        var active = (page.getPath() == currentNavPath);

        items.push({
            page: page,
            active: active
        });

    };

    return {
        info: info,
        items: items
    };
});

            active: active
        });

    };

    return {
        info: info,
        items: items
    };
});

 

I can able to invoke java class using the sightly tag data-sly-use.settings="com.xxx.Settings" ,  Give a try and hope it works.
