MyFaces和WebSphere Liberty概要文件(ClassNotFoundException)

问题描述

我已经在WebSphere Liberty Profile(16.0.0.3)上成功部署了我的应用程序，但是当我尝试使用它时，出现以下异常:

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 com.ibm.ws.classloading.internal.AppClassLoader.findClass(AppClassLoader.java:271)

    at java.lang.Class.forName(Class.java:264)
    at pt.sibs.epms.ecc.renderer.HtmlFormRenderer.getRenderer(HtmlFormRenderer.java:54)

在server.xml中启用了JSF 2.2:

JSF 2.2 is enabled in server.xml:

<feature>jsf-2.2</feature>

该类存在于:

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

关于API类型的可见性，我的共享库和应用程序都具有spec,ibm-api,api,third-party.

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

如果我尝试配置MyFaces的另一个实现，则会开始获取ClassCastException.

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

要进行这项工作，我需要更改什么?

What do I need to change to make this work?

推荐答案

jsf-2.2功能不会将MyFaces实现类公开为任何类型的api，这就是为什么尝试Class.forName不能正常工作的原因

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.
