Sightly Component Cannot Find Bundled WCMUse(Pojo)
I've been following the documentation here
Apparently, in order to have my "use" class be visible to my Sightly component, all I need to do is use the full Class name (i.e. including the package) in my "use" statement.
<div data-sly-use.listChildren="com.t4g.aem.impl.usebeans.ListChildrenUseBean"><!-- Markup --></div>
I've followed the directions and built and deployed my bundle. My compiled class is in there (I cracked the JAR to make certain.) and still, the Sightly engine cannot find my class. I've tried WCMUse and WCMUsePojo. I've tried alternate syntaxes in the Sightly markup (I've found variants here and there). Nothing seems to works for a bundled use bean.
If I drop the same class into the component and update the package to match, everything works fine.
I'd love to know:
- If anybody has ever actually gotten this to work
- How to get it to work
Thank you for your help.
The exception I get is:
org.apache.sling.scripting.sightly.SightlyException: Identifier
com.t4g.aem.impl.usebeans.ListChildrenUseBean cannot be correctly
instantiated by the Use API
[...]
Caused by: org.apache.sling.scripting.sightly.SightlyException: Cannot

The full exception trace is as follows (it's really long, sorry):

Here's the solution I found, thanks to some help I received elsewhere.
To avoid this issue, you need to make sure that the bundle's OSGi manifest's import-package (i.e. dependencies) and export-package (i.e. your "Use" classes) reflect the classes you want exposed to your Sightly scripts. This will allow Felix to be aware of them and inject them wherever they're needed.
Here is an example snipped from from my test code's config (i.e. myproject-bundle/pom.xml):
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<extensions>true</extensions>
<configuration>
<instructions>
<Bundle-SymbolicName>com.us.aem.sightly-stuff-bundle</Bundle-SymbolicName>
<Export-Package>
<!-- Let's export our primary package -->
com.us.aem.impl.usebeans
<!-- By default, don't export any other packages -->
</Export-Package>
<Import-Package>
<!-- JSR 250 && 330 -->
javax.annotation;version=0.0.0.1_007_JavaSE,
javax.inject,
<!-- JEE Servlet -->
javax.servlet,
javax.servlet.http,
<!-- Sling -->
org.apache.sling.api,
org.apache.sling.api.resource,
org.apache.sling.auth.core,
org.apache.sling.jcr.api,
com.day.cq.commons,
org.apache.sling.api.request,
com.adobe.cq.sightly,
com.day.cq.wcm.api,
org.slf4j
</Import-Package>
</instructions>
</configuration>
</plugin>
The reason why I overlooked this is that this step isn't necessary for the classes I'm used to creating in bundles (e.g. OSGi services such a Servlets, Schedulers, etc.) In those, I use Felix SCR annotations that allow a different plugin to pick up the classes and add them to the manifest automatically. (I believe it is the org.apache.felix.maven-scr-plugin that does this.)
The bottom line is that for a class to be visible outside an OSGi bundle, it needs to be registered in the manifest. Sometimes we use org.apache.felix.scr.annotations, sometimes we need to explicitly tell our Maven build about them.
Hopefully this answer can be of help to people who run into this same issue. Once you know what's missing, it all makes sense.
Thanks!
