有人在 ServiceMix4 中成功通过 Spring OSGi Web 运行 Tomcat 吗？

Question

我们已经在标准 OSGi 应用程序中使用 Fuse 的 Apache ServiceMix 版本 4.2.0-fuse-02-00 一段时间了，并且取得了相当成功。我们还一直在利用 CXF 来提供 Web 服务。

现在，我们希望将 Web 应用程序部署到 servicemix4 并利用 OSGi 层来实现依赖项和服务。然而，PAX Web 中的打包似乎不支持我们经常使用的标签库：Richfaces、facelets 等。 似乎允许工作标签库的 springDM 解决方案概述如下： http://static.springsource.org/osgi/docs/current/reference/html/web.html 应该可以，但是我很难启动网络服务器，我目前收到此错误。

我已经按照 Spring 文档的建议创建了 2 个片段。但它们不会解析，它们仍保持为已安装

1) 网络服务器配置片段 定义了以下片段主机：

<Fragment-Host>org.springframework.osgi.web.extender</Fragment-Host>

并且有一个文件 META-INF/spring/extender/tomcat-deployer.xml 包含

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="http://www.springframework.org/schema/beans   
       http://www.springframework.org/schema/beans/spring-beans.xsd">
 <bean id="warDeployer"
        class="org.springframework.osgi.web.deployer.tomcat.TomcatWarDeployer" />

</beans>

2) 和一个 Catalina Config 片段 具有以下主机：

<Fragment-Host>org.springframework.osgi.catalina.start.osgi</Fragment-Host>

并定义了conf/server.xml，它主要是tomcat 6 server.xml文件的通用Windows安装的副本。

这几天我也一直在搞乱依赖关系，这很困难。但为了达到这个目的，我一直在搞乱以下功能。我还安装了fuse-servicemix 默认的“jpa-hibernate”功能。

我考虑过切换到 SpringDM，但该项目似乎已转移到 Virgo，目前仅处于孵化器中。另外，我们对 Sericemix 非常满意，包括它的 Maven 安装功能。

任何见解或资源将不胜感激， 谢谢， 杰里米

Answer 1

因此，在休息一段时间后，我回来与团队中的更多成员一起解决这个问题。
简而言之，我们使用 SpringDM 成功在 ServiceMix 中获取了 Tomcat。
我将列出我在尝试进行此设置时所犯的一些错误。

1）ServiceMix的刷新功能会重新分析POM，因此只有刷新其主机后，片段才会被解析。这就是为什么我的仍然处于安装状态

2) 我实际上不需要这两个片段中的任何一个，这两个片段都有适合在 tomcat 中启动的默认值。

3) 我缺少 catalalina.start.osgi 包，它是向 osgi 层提供 tomcat 服务所必需的，更具体地说是 Spring DM 的 Web 扩展器。然而，我错过了它，因为我错过了 3 个关键存储库。以下是我们关于这些存储库的 Nexus 信息：

Repository ID: springframework.osgi
Repository Name: Springframework OSGI
Repository Type: proxy
Repository Policy: Release
Repository Format: maven2
Contained in groups: 
   Public Repositories
Remote URL: http://maven.springframework.org/osgi/

Repository ID: com.springsource.repository.bundles.release
Repository Name: SpringSource Enterprise Bundle Repository - SpringSource Bundle Releases
Repository Type: proxy
Repository Policy: Release
Repository Format: maven2
Contained in groups: 
   Public Repositories
Remote URL: http://repository.springsource.com/maven/bundles/release/

Repository ID: com.springsource.repository.bundles.milestones
Repository Name: SpringSource Enterprise Bundle Repository - SpringSource Bundle Milestones
Repository Type: proxy
Repository Policy: Release
Repository Format: maven2
Contained in groups: 
   Public Repositories
Remote URL: http://repository.springsource.com/maven/bundles/milestone/

我们还有 4 个其他 SpringSource Enterprise Repos（以防万一）

Repository ID: com.springsource.repository.bundles.external
Repository Name: SpringSource Enterprise Bundle Repository - External Bundle Releases
Repository Type: proxy
Repository Policy: Release
Repository Format: maven2
Contained in groups: 
   Public Repositories
Remote URL: http://repository.springsource.com/maven/bundles/external/

Repository ID: com.springsource.repository.libraries.external
Repository Name: SpringSource Enterprise Bundle Repository - External Library Releases
Repository Type: proxy
Repository Policy: Release
Repository Format: maven2
Contained in groups: 
   Public Repositories
Remote URL: http://repository.springsource.com/maven/libraries/external/

Repository ID: com.springsource.snapshot
Repository Name: SpringSource Enterprise Bundle Repository - SpringSource Bundle Snapshots
Repository Type: proxy
Repository Policy: Snapshot
Repository Format: maven2
Contained in groups: 
   Public Repositories
Remote URL: http://repository.springsource.com/maven/bundles/snapshot/

Repository ID: com.springsource.repository.libraries.release
Repository Name: SpringSource Enterprise Bundle Repository - SpringSource Library Releases
Repository Type: proxy
Repository Policy: Release
Repository Format: maven2
Contained in groups: 
   Public Repositories
Remote URL: http://repository.springsource.com/maven/libraries/release/

因此，除了 servicemix 上的 coyote 之外，我们还将这两个片段添加到了 catalina 捆绑包中：

<bundle>mvn:org.springframework.osgi/catalina.start.osgi/1.0.0</bundle>
<bundle>mvn:org.apache.jasper/com.springsource.org.apache.jasper/6.0.24</bundle>

jsp 需要 jasper 捆绑包。4

）添加后捆绑包，刷新并重新启动适当的捆绑包，Tomcat 启动并运行良好。我们可以点击 localhost:8080 并点击空白页。我们决定尝试部署 Spring-DM 下载中提供的 simple-web-app：

http://www.springsource.org/osgi

解决了一些依赖问题后，我们能够清理和构建这个 Web 应用程序并部署它。在我们的 Ubuntu 环境中，您可以看到它将战争爆发到 /tmp/ 目录，它将从该目录为 Web 应用程序提供服务。不幸的是，当我们尝试访问 http://localhost:8080/simple-web-app/< 时，我们得到了 404 错误/a> 经过一些 Tomcat 调试后，我们意识到 Tomcat 的安装不知何故没有看到通常的默认 web.xml servlet 信息。因此，与此同时，我们必须在 Web 应用程序的 web.xml 中包含默认 servlet：

    <servlet>
        <servlet-name>default</servlet-name>
        <servlet-class>org.apache.catalina.servlets.DefaultServlet</servlet-class>
        <init-param>
            <param-name>debug</param-name>
            <param-value>0</param-value>
        </init-param>
        <init-param>
            <param-name>listings</param-name>
            <param-value>false</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

<servlet>
    <servlet-name>jsp</servlet-name>
    <servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
    <init-param>
        <param-name>fork</param-name>
        <param-value>false</param-value>
    </init-param>
    <init-param>
        <param-name>xpoweredBy</param-name>
        <param-value>false</param-value>
    </init-param>
    <load-on-startup>3</load-on-startup>
</servlet>

    <!-- The mapping for the default servlet -->
    <servlet-mapping>
        <servlet-name>default</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <!-- The mapping for the JSP servlet -->
    <servlet-mapping>
        <servlet-name>jsp</servlet-name>
        <url-pattern>*.jsp</url-pattern>
    </servlet-mapping>

    <servlet-mapping>
        <servlet-name>jsp</servlet-name>
        <url-pattern>*.jspx</url-pattern>
    </servlet-mapping>

进一步调查为什么我们的示例应用程序无法找到默认 servlet 如下：

http://forum.springsource.org/showthread.php?p=328657#post328657

所以此时我们似乎已经掌握了一切根据这个 spring 示例，根据需要启动并运行工作标签库。尽管我们仍然需要尝试使用 OSGi 类路径从 Web 应用程序加载资源，或使用 OSGi 服务，但我们至少迈出了第一步。

请注意，即使我们没有使用 Wicket，此链接对于验证我所做的事情非常有帮助。
