将JAX-WS作为OSGi包部署到Karaf上

Question

我尝试将一个简单的JAX-WS web服务作为OSGi包部署到Karaf上。在将web服务导出为War文件并将其部署到Karaf的/deploy文件夹后，我发现通过http://localhost:8181/HelloWebService/helloWebService

无法访问它。

我的代码很简单，我只是使用这个https://github.com/yngwietiger/HelloWebService.git。

web.xml如下:

<?xml version="1.0" encoding="UTF-8"?>

     id="WebApp_ID" version="2.5">
<display-name>jaxwsExample</display-name>

    <listener-class>com.sun.xml.ws.transport.http.servlet.WSServletContextListener</listener-class>
</listener>
<servlet>
    <servlet-name>helloWebService</servlet-name>
    <servlet-class>com.sun.xml.ws.transport.http.servlet.WSServlet</servlet-class>

</servlet>

<servlet>
    <servlet-name>myservlet</servlet-name>
    <servlet-class>com.webservices.demo.MyServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>myservlet</servlet-name>
    <url-pattern>/myservlet</url-pattern>
</servlet-mapping>
<session-config>
    <session-timeout>120</session-timeout>
</session-config>

日志是:

通过使用web:list，它显示231包是活动的，并且一直在部署。

如何用OSGi部署标准的JAX-WS web服务(不是JXC，只是简单的JAX-WS web服务)?
通过使用Karaf或构建一个Jetty OSGi环境或其他…

Answer 1

您提到的示例使用maven。它构建的通用WAR文件不包含正确的OSGi清单，也不生成任何与jaxws相关的内容。为了创建公开web服务的OSGi WAB (web archive bundle)，你必须使用适当的maven插件，例如:用于生成WSDL的jaxws-maven-plugin;maven-war-plugin和maven-bundle-plugin一起构建WAB。实际上，maven-bundle-plugin可以自己构建wab。
