 web.xml

   <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/pluto-portal-driver-services-config.xml</param-value>
    </context-param>

web.xml里面可以定义两种参数：
(1)application范围内的参数，存放在servletcontext中，在web.xml中配置如下：

如上

(2)servlet范围内的参数，只能在servlet的init()方法中取得，在web.xml中配置如下：

<servlet>
    <servlet-name>MainServlet</servlet-name>
    <servlet-class>com.wes.controller.MainServlet</servlet-class>
    <init-param>
       <param-name>param1</param-name>
       <param-value>avalible in servlet init()</param-value>
    </init-param>
    <load-on-startup>0</load-on-startup>
</servlet>

在servlet中可以通过代码分别取用：

package com.wes.controller;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;

public class MainServlet extends HttpServlet ...{

    public MainServlet() ...{
        super();
     }
    public void init() throws ServletException ...{
         System.out.println("下面的两个参数param1是在servlet中存放的");
         System.out.println(this.getInitParameter("param1"));
         System.out.println("下面的参数是存放在servletcontext中的");
         System.out.println(getServletContext().getInitParameter("contextConfigLocation"));
      }
}

第一种参数在servlet里面可以通过getServletContext().getInitParameter("contextConfigLocation")得到
第二种参数只能在servlet的init()方法中通过this.getInitParameter("param1")取得

转入：org.apache.pluto.driver.config.impl.DriverConfigurationImpl的构造方法

public DriverConfigurationImpl(PortalURLParser portalUrlParser【org.apache.pluto.driver.url.impl.PortalURLParserImpl】,
                                   PropertyConfigService propertyService【org.apache.pluto.driver.services.impl.resource.PropertyConfigServiceImpl】,
                                   RenderConfigService renderService【org.apache.pluto.driver.services.impl.resource.RenderConfigServiceImpl】,
                                   SupportedModesService supportedModesService,

                                   PortalCallbackService portalCallback【org.apache.pluto.driver.services.container.PortalCallbackServiceImpl】)

参数都是由pluto-portal-driver-services-config.xml配置决定的

【转入】

org.apache.pluto.driver.PortalStartupListener的方法：

public void contextInitialized(ServletContextEvent event) {
        LOG.info("Starting up Pluto Portal Driver. . .");

        ServletContext servletContext = event.getServletContext();

        WebApplicationContext springContext = null;
       
        try {
            springContext = (WebApplicationContext)
                servletContext.getAttribute(WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE);
           
        } catch (RuntimeException ex) {
            String msg = "Problem getting Spring context: " + ex.getMessage();
            LOG.error(msg, ex);
            throw ex;
        }
    
        LOG.debug(" [1a] Loading DriverConfiguration. . . ");
        DriverConfiguration driverConfiguration = (DriverConfiguration)
                springContext.getBean("DriverConfiguration");

        driverConfiguration.init(servletContext);

        LOG.debug(" [1b] Registering DriverConfiguration. . .");
        servletContext.setAttribute(DRIVER_CONFIG_KEY, driverConfiguration);


        LOG.debug(" [2a] Loading Optional AdminConfiguration. . .");
        AdminConfiguration adminConfiguration = (AdminConfiguration)
                springContext.getBean("AdminConfiguration");

        if (adminConfiguration != null) {
            LOG.debug(" [2b] Registering Optional AdminConfiguration");
            servletContext.setAttribute(ADMIN_CONFIG_KEY, adminConfiguration);
        } else {
            LOG.info("Optional AdminConfiguration not found. Ignoring.");
        }

        initContainer(servletContext);

        LOG.info("********** Pluto Portal Driver Started **********/n/n");
    }

 

DriverConfiguration driverConfiguration = (DriverConfiguration)
                springContext.getBean("DriverConfiguration");

        driverConfiguration.init(servletContext);

org.apache.pluto.driver.config.impl.DriverConfigurationImpl的方法：

public void init(ServletContext context) {
        this.propertyService.init(context);
        this.renderService.init(context);
        this.supportedModesService.init(context);
        this.supportedWindowStateService.init(context);
    }

this.propertyService.init(context);对应如下代码：

package org.apache.pluto.driver.services.impl.resource.PropertyConfigServiceImpl的

public void init(ServletContext ctx) {
        try {
            InputStream in = ctx.getResourceAsStream(ResourceConfigReader.CONFIG_FILE);
            config = ResourceConfigReader.getFactory().parse(in);
        }
        catch(Exception e) {
            LOG.error("Unable to parse resource config "+e.getMessage(), e);
            throw new DriverConfigurationException(e);
        }
    }方法

其中ResourceConfigReader.CONFIG_FILE是在org.apache.pluto.driver.services.impl.resource.ResourceConfigReader类中静态定义的

public static final String CONFIG_FILE =
        "/WEB-INF/pluto-portal-driver-config.xml";

 

this.renderService.init(context);对应如下代码：

org.apache.pluto.driver.services.impl.resource.RenderConfigServiceImpl的

public void init(ServletContext ctx) {
        try {
            InputStream in = ctx.getResourceAsStream(ResourceConfigReader.CONFIG_FILE);
            config = ResourceConfigReader.getFactory().parse(in);
        }
        catch(Exception e) {
            throw new DriverConfigurationException(e);
        }
    }

 

this.supportedModesService.init(context);对应如下代码：

org.apache.pluto.driver.services.impl.resource.SupportedModesServiceImpl的

public void init(ServletContext ctx) throws DriverConfigurationException {
        this.servletContext = ctx;
        this.portletContextService = portletContextService = PlutoServices.getServices().getPortletContextService();
        loadPortalModes();
    }

 

this.supportedWindowStateService.init(context);对应如下代码：

 

org.apache.pluto.driver.services.impl.resource.SupportedWindowStateServiceImpl的

public void init(ServletContext ctx) throws DriverConfigurationException
    {
        LOG.debug( "Initializing SupportedWindowStateService... " );

        servletContext = ctx;
       
        portalSupportedWindowStates = propertyService.getSupportedWindowStates();
        if ( LOG.isDebugEnabled() )
        {
            StringBuffer msg = new StringBuffer();
           
            if ( portalSupportedWindowStates != null )
            {
                msg.append( "Portal supports [" + portalSupportedWindowStates.size() + "] window states.  ");
                for ( Iterator i = portalSupportedWindowStates.iterator(); i.hasNext(); )
                {
                    msg.append( "[" + i.next() + "]" );
                    if ( i.hasNext() )
                    {
                        msg.append(", ");
                    }
                }
                LOG.debug(msg.toString());
            }   
        }
       
        if ( portalSupportedWindowStates == null )
        {
            final String msg = "Portal supported window states is null!";
            LOG.error( msg );
            throw new DriverConfigurationException( msg );
        }
        LOG.debug( "SupportedWindowStateService initialized." );       
    }
