本文介绍了JavaServer Faces 2.2需要动态Web模块2.5或更新版本的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
无法安装JavaServer Faces 2.2：一个或多个约束尚未满足
JavaServer Faces 2.2需要动态Web模块2.5或更高版本
1）我尝试了几件事如 Maven Java EE配置标记与Java中所述服务器面孔1.2 ，但没有运气。
2）另外我进入了.settings并修改了org.eclipse.wst.common.project.facet.core.xml，并将jst.web修改为2.5或3.0版本;但是我收到一些其他错误。
我试图使Sencha GXT示例在基于 http://neiliscoding.blogspot.ie/2012/05/how- to-setup-examples-for-use-in-gxt-3.html ，并在eclipse中使这个javaserver面临问题。
这是我的pom.xml

如你所见，我在web.xml中尝试了不同的dtds，但是我仍然有问题。感谢任何提示
解决方案
您的问题是您将web.xml标记为符合servlet 2.3（或者甚至不符合那个 - 我不知道你的评论中的doctype是如何解释的）
<？xml version =1.0encoding = UTF-8 >？;
<！ - ！DOCTYPE web-app
PUBLIC - // Sun Microsystems，Inc.//DTD Web应用程序2.3 // EN
http：// java .sun.com / DTD /网络app_2_3.dtd>
，您需要至少符合Eclipse工具的servlet 2.5兼容性。 >
<？xml version =1.0encoding =UTF-8？>

xsi：schemaLocation =http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web- app_2_5.xsd>
（未经测试 - 从 http://javahowto.blogspot.dk/2009/10/sample-webxml-servlet-25.html ）
您可能需要重新创建Eclipse项目才能更改。
I tried few things, but still this problem persists. I am using Eclipse Kepler. I get following error on importing maven project
JavaServer Faces 2.2 can not be installed : One or more constraints have not been satisfied
JavaServer Faces 2.2 requires Dynamic Web Module 2.5 or newer
1) I tried few things as mentioned in Maven Java EE Configuration Marker with Java Server Faces 1.2, but no luck. 2)Also I went into .settings and modified org.eclipse.wst.common.project.facet.core.xml and modified jst.web to point to 2.5 or 3.0 version; but I get some other errors.
I am trying to make Sencha GXT examples work in maven/eclipse build based on http://neiliscoding.blogspot.ie/2012/05/how-to-setup-examples-for-use-in-gxt-3.html and having this javaserver faces problem in eclipse. Here is my pom.xml

As you can see, I tried different dtds in above web.xml, but I still have the problem. Would appreciate any hints
解决方案
Your problem is that you have marked your web.xml as being servlet 2.3 compliant (or perhaps not even that - I am not sure how your doctype in a comment is interpreted)
<?xml version="1.0" encoding="UTF-8"?>
<!-- <!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">
and you need it to be at least servlet 2.5 compliant for the Eclipse tooling to work.
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
(untested - copied from http://javahowto.blogspot.dk/2009/10/sample-webxml-servlet-25.html)
You may need to recreate the Eclipse project to have the changes picked up.
