MyFaces and WebSphere Liberty Profile (ClassNotFoundException)

问题

I've successfully deployed my app on WebSphere Liberty Profile (16.0.0.3), but when I try to use it, I get the following exception:

java.lang.ClassNotFoundException: org.apache.myfaces.renderkit.html.HtmlFormRenderer
    at com.ibm.ws.classloading.internal.AppClassLoader.findClassCommonLibraryClassLoaders(AppClassLoader.java:488)

    at pt.sibs.epms.ecc.renderer.HtmlFormRenderer.getRenderer(HtmlFormRenderer.java:54)

JSF 2.2 is enabled in server.xml:

<feature>jsf-2.2</feature>

And the class exists in:

wlp/lib/com.ibm.ws.jsf.2.2_1.0.14.jar

Regarding API type visibilty, both my shared library and application have spec,ibm-api,api,third-party.

If I try to configure another implementation of MyFaces, I start getting ClassCastException.

What do I need to change to make this work?

回答1:

The jsf-2.2 feature doesn't expose the MyFaces implementation classes as api of any kind which is why the attempt to do a Class.forName isn't working.

回答2:

Hi you should be able to implement your own Renderers by using a combination of the RendererWrapper and the RenderKitWrapper. These classes allow you to add specialized behavior to existing Renderer and RenderKit instances.
