Apparently, you're not missing anything else. Just try to do the following:

<ol>
<li>Ensure that the necessary jars exist in the "lib" project folder;</li>
<li>Do clean &amp; build;</li>
</ol>

In the end, you should find those included jars, available within the "build" project folder.

If you tried to convert your simple java project to web project using maven and changing specificications from project facets, you won't get a compile error but when you start deployment you can see this error message.

to solve this think of it. This is a web project and needs to deploy as a war file (or ear). 

change packaging spec to war in your pom.xml then compile maven again.

blocks|key|40906|text|我遇到了类似的问题，在运行Maven+Update几次后得到了解决，最后Maven+Update解决了这个问题。只运行一次是不够的，因为jar文件仍然损坏，所以您需要确保使用任何压缩工具打开它，如winzip或gzip。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|40907|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I had a similar issue and solved after running Maven Update a couple of times when it finally solved the issue. Running only once was not enough because the jar file was still corrupt so you need to make sure it opens with any compression tool like winzip or gzip.

I am getting this error, when executing JSF and PrimeFaces.

I have included these jars,

<ul>
<li>jsf-api-2.0.3.jar,</li>
<li>jsf-impl-2.0.3.jar ,</li>
<li>jstl-1.0.2.jar jars and</li>
<li>primefaces-2.2.RC2.jar</li>
</ul>

in the <code>WEB-INF/lib</code> folder.

Is there any jar I am missing?

在执行JSF和PrimeFaces时，我得到了这个错误。我把这些罐子也包括进去了，jsf-api-2.0.3.jar，jsf-impl-2.0.3.jar、jstl-1.0.2.jar jars andprimefaces-2.2.RC2.jar在WEB-INF/lib文件夹中。我是不是丢了什么罐子？
