Question

我在karaf / servicemix中部署一个简单的.war文件时出现以下错误。如果我遗失了什么，请告诉我。

ERROR：

代码如下：

的Manifest.MF：

Manifest-Version: 2 
Bundle-SymbolicName: JDBCWebDemo 
Bundle-Version: 2.3 
Bundle-ClassPath: WEB-INF/classes 
Import-Package: javax.servlet,javax.servlet.http

的web.xml：

<web-app ...>
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
  </welcome-file-list>
  <servlet>
    <description></description>
    <display-name>ConnectServlet</display-name>
    <servlet-name>ConnectServlet</servlet-name>
    <servlet-class>app.web.servlet.ConnectServlet</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>ConnectServlet</servlet-name>
    <url-pattern>/ConnectServlet</url-pattern>
  </servlet-mapping>
</web-app>

Answer 1

您的OSGi包很可能需要导出具有servlet代码的包，例如在您需要的MANIFEST.MF文件中

Export-Package: app.web.servlet

Answer 2

如果它不在你的战争中，你需要导入正确的包。

Import-Package: app.web.servlet

或者如果它位于lib文件夹中的一个lib中，则需要确保所有这些jar都包含在类路径中：

Bundle-ClassPath: WEB-INF/classes, WEB-INF/lib/jar1.jar, ....
