java - 如何在 Netbeans 中从 Maven 安装 PrimeFaces？我收到警告，标签库 http ://primefaces. org/ui 不存在

Question

我测试部署这个 example来自 PrimeFaces。

我不知道为什么它不起作用。我收到此错误消息:

警告:此页面调用 xml 命名空间 http://primefaces.org/ui用前缀 p 声明，但该命名空间不存在 taglibtrary

我关注这个tutorial正确安装 jar 。我下载了 Primefaces jar 文件并将其添加到 resources目录到 WAR 文件中。

    <dependency>
        <groupId>org.primefaces</groupId>
        <artifactId>primefaces</artifactId>
        <version>3.3</version>
        <type>jar</type>
    </dependency>

我还将 Primefaces.jar 文件添加到 Glassfish 的/modules 目录中，并将模块的名称添加到 default-web.xml 文件中。它不起作用。

我错过了什么？

编辑 2 我是正确的 POM 文件是问题所在:

    </repositories>
    <description>Module History Module</description>
</project>

必须添加这些行才能使 Primefaces 正常工作:

<instructions>
    <!-- Read all OSGi configuration info from this optional file -->
    <_include>-osgi.properties</_include>
    <!-- By default, we don't export anything -->
    <Export-Package>!*.impl.*, *</Export-Package>
    <DynamicImport-Package>javax.*, org.*, com.sun.faces.*</DynamicImport-Package>
    <Import-Package>*;resolution:=optional</Import-Package>
    <Embed-Dependency>*;scope=compile|runtime;inline=false</Embed-Dependency>
    <Embed-Transitive>true</Embed-Transitive>
    <Embed-Directory>WEB-INF/lib</Embed-Directory>
    <Embed-StripVersion>false</Embed-StripVersion>
    <Embed-StripGroup>true</Embed-StripGroup>
    <Bundle-ClassPath>.,WEB-INF/classes</Bundle-ClassPath>
</instructions>

但我注意到一个很奇怪的问题。例如，我可以使用没有 managedbean 的简单 PrimeFaces 标签 <p:spinner>但是如果我想将标签与托管 bean 一起使用，则找不到 bean。也许它们是不可见的？

Answer 1

我只是按照 Primefaces 下载指南中的步骤操作:

http://primefaces.org/downloads.html

使用 Maven 下载

PrimeFaces 发行版部署在 PrimeFaces 存储库中，要让 maven 知道此存储库，请将以下存储库定义添加到存储库部分的 pom.xml 中。

<repository>  
  <id>prime-repo</id>  
  <name>PrimeFaces Maven Repository</name>  
  <url>http://repository.primefaces.org</url>  
  <layout>default</layout>  
</repository>  

并添加依赖配置为；

<dependency>
  <groupId>org.primefaces</groupId>
  <artifactId>primefaces</artifactId>
  <version>3.3</version>
</dependency>

之后，我将 Primefaces 存储库添加到我的 Nexus 安装中，它按预期工作。

希望对你有帮助!
