hi All,

I am facing the issue while using the java in sightly i am extending my java class from WCMUsePojo;

Below is hierarchy.

TopNav.java

import com.day.cq.sightly.WCMUsePojo;

and using this java class in sightly component using the below code

site-topnav.html

<a href="${topnav.root.path}.html">we.<strong>train</strong></a>

<a href="${item.path}.html">${item.title}</a>

</li>

</div>

But i am getting the error on browser while accessing this component

org.apache.sling.api.scripting.ScriptEvaluationException: org.apache.sling.scripting.sightly.impl.compiler.CompilerException: org.apache.sling.scripting.sightly.impl.compiler.CompilerException: Compilation errors in apps/training/components/site_topnav/TopNav.java:

Line 7, column 177 : Only a type can be imported. com.day.cq.sightly.WCMUsePojo resolves to a package

Can someone please suggest me how to resolve this.

Hi,

We could see from your code snippet that you had used "import com.day.cq.sightly.WCMUsePojo;"

Sightly APIs were introduced from 6.x onwards. Although there is feature pack of sightly available in 5.6.1, but that is just to see sightly preview and won't support sightly APIs completely. This is the reason behind the error that you're seeing.

We had tried using "import com.adobe.cq.sightly.WCMUsePojo;" and your code works fine for us in AEM 6.x.

NOTE:

1. The field WCMUsePojo.currentPage won't be visible.

Hence you should be using getCurrentPage() instead of currentPage in your code.

2. When you've hyphen in your component name, then you should be mentioning the package name as below:

package apps.training.components.site_topnav;

i.e. hyphen must be replaced with underscore in your package name to get your code working.

Sample java code:

package apps.training.components.site_topnav;
import java.util.*;
import com.day.cq.wcm.api.*;
import com.adobe.cq.sightly.WCMUsePojo;
public class TopNav extends WCMUsePojo {
private List<Page> items=new ArrayList<Page>();
private Page rootPage;
@Override   
   public void activate() throws Exception{
   rootPage=getCurrentPage().getAbsoluteParent(2);
   
        if(rootPage==null)
        {
            rootPage=getCurrentPage();
        }
        Iterator<Page> childPages=rootPage.listChildren(new PageFilter(getRequest()));
        while(childPages.hasNext())
        {
            items.add(childPages.next());
        }
     }
        
    public List<Page> getItems()
    {
        return items;
    }
    public Page getPage()
    {
        return rootPage;
    }
}
}

Sample sightly code:

<div data-sly-use.topnav="${'TopNav'}">
    <a href="${topnav.page.path}.html">we.<strong>train</strong></a>
<ul>
    <li data-sly-repeat="${topnav.items}">
    <a href="${item.path}.html">${item.name}</a><br/>
    </li>
    </ul>   
</div>

We hope this helps!

Hi edubey,

I am facing the similar issue in fetching the WCMUse Pojo Java class in sightly Page.

Thanks for your explanation!!. It helped me a lot.

Hi,

We could see from your code snippet that you had used "import com.day.cq.sightly.WCMUsePojo;"

We had tried using "import com.adobe.cq.sightly.WCMUsePojo;" and your code works fine for us in AEM 6.x.

NOTE:

1. The field WCMUsePojo.currentPage won't be visible.

Hence you should be using getCurrentPage() instead of currentPage in your code.

2. When you've hyphen in your component name, then you should be mentioning the package name as below:

package apps.training.components.site_topnav;

i.e. hyphen must be replaced with underscore in your package name to get your code working.

Sample java code:

package apps.training.components.site_topnav;
import java.util.*;
import com.day.cq.wcm.api.*;
import com.adobe.cq.sightly.WCMUsePojo;
public class TopNav extends WCMUsePojo {
private List<Page> items=new ArrayList<Page>();
private Page rootPage;
@Override   
   public void activate() throws Exception{
   rootPage=getCurrentPage().getAbsoluteParent(2);
   
        if(rootPage==null)
        {
            rootPage=getCurrentPage();
        }
        Iterator<Page> childPages=rootPage.listChildren(new PageFilter(getRequest()));
        while(childPages.hasNext())
        {
            items.add(childPages.next());
        }
     }
        
    public List<Page> getItems()
    {
        return items;
    }
    public Page getPage()
    {
        return rootPage;
    }
}
}

Sample sightly code:

<div data-sly-use.topnav="${'TopNav'}">
    <a href="${topnav.page.path}.html">we.<strong>train</strong></a>
<ul>
    <li data-sly-repeat="${topnav.items}">
    <a href="${item.path}.html">${item.name}</a><br/>
    </li>
    </ul>   
</div>

We hope this helps!
