Myfaces ServletContext ‘null’ 已初始化

Myfaces ServletContext 'null' initialized

问题

I'm migrating an application from a WebSphere 8.5.5.x environment to Liberty 20.0.0.3. I got most of it working except the JSF part. Something is wrong with the initialization and I can't figure out what it is nor how to debug it. Since this library is supplied by Liberty I can't just put breakpoints to debug.

I can give the following comparison

First thing that is strange he is doing it twice on the liberty setup, second thing is that the ServletContext is 'null'.

Maybe I'm missing a setting in web.xml or faces-config.xml is wrong. I'm not sure, WebSphere might be a bit more lenient than Liberty and fix some stuff for me.

Has anyone got any experience with loading MyFaces?

这个ServletContext 'null' initialized消息是由一个旧的MyFaces bug引起的:MYFACES-3356。不幸的是,Liberty jsf-2.0 实现似乎没有这个修复 - 建议向IBM开启一个支持工单可能是值得的。

作为一种解决方法,如果对您的应用程序可行,您可以通过在server.xml中使用<applicationManager autoExpand="true"/>来启用应用程序扩展。

英文:

This ServletContext &#39;null&#39; initialized message is caused by an older MyFaces bug: MYFACES-3356. Unfortunately the Liberty jsf-2.0 implementation doesn't appear to have that fix - it would be worthwhile to open a support ticket with IBM.

As a workaround, if it's workable for your app you can enable application expansion in your server.xml via &lt;applicationManager autoExpand=&quot;true&quot;/&gt;

所以在与同事合作后,我们发现了 JSF 未能渲染的问题。希望这是正确的解决方案,我不得不将以下内容追加到功能堆栈中:

<feature>webProfile-6.0</feature>

突然之间,JSF 就恢复正常了。我们还尝试将其移除,然后只添加以下内容:

<feature>managedBeans-1.0</feature>

但那还不够,所以我们决定保持 WebProfile,即使它会引入一些我们可能不需要的额外功能。

英文:

So after collaborating with a co worker we found the issue why JSF wasn't rendering. Well we hope it's the right solution I had to append

&lt;feature&gt;webProfile-6.0&lt;/feature&gt;

to the feature stack, and all of the sudden JSF came to life. We also tried removing it and then just adding

&lt;feature&gt;managedBeans-1.0&lt;/feature&gt;

but that wasn't enough, so we settled on just keeping the webprofile even if it pulls in some more features we might not need
