Jetspeed2学习笔记(一)(转载)

 
   
1、 Jetspeed系统的配置文件在《JetSpeed2 home》/conf/Catalina/localhost下的jetspeed.xml文件中,此文件中定义了JAAS验证的配置及 数据库连接模式(包括连接语句)

2、配置一个居于IFrame的应用:

 

1、  引入jar包:jetspeed-components-2.0.jar

jetspeed-rewriter-2.0.jar

jetspeed-web-content-2.0.jar

portals-bridges-velocity-1.0.jar

portals-gems-2.0.jar

注:可以使用demo应用的lib

 

2、  在portal.xml文件中配置一个portlet:

<portlet id="EchoIframe">

    <portlet-name>EchoIframe</portlet-name>

    <display-name>lixin IFrame Portlet</display-name>

    <description>Prototype of the IFRAME2 portlet</description>

    <portlet-class>org.apache.jetspeed.portlet.IFrameGenericPortlet</portlet-class>

    <expiration-cache>-1</expiration-cache>

    <supports>

      <mime-type>text/html</mime-type>

      <portlet-mode>VIEW</portlet-mode>

    </supports>

    <portlet-preferences>

      <preference>

        <name>SRC</name>

        <value>http://www.sohu.com</value>

      </preference>

      <!-- Don't specify a HEIGHT if you want a normal filled out layout

     because percentage values result in the content not to be displayed on IE6.

     Specific values are ok though.

-->

      <preference>

                            <name>HEIGHT</name>

                            <value>600</value>

                     </preference>

      <preference>

        <name>WIDTH</name>

        <value>100%</value>

      </preference>

      <preference>

        <name>MAX-HEIGHT</name>

        <value>800</value>

      </preference>

      <preference>

        <name>MAX-WIDTH</name>

        <value>100%</value>

      </preference>

      <preference>

        <name>SCROLLING</name>

        <value>AUTO</value>

      </preference>

    </portlet-preferences>

    <supported-locale>en</supported-locale>

    <supported-locale>zh</supported-locale>

    <portlet-info>

      <title>搜狐网</title>

      <short-title>搜狐网</short-title>

      <keywords>iframe,frame,frame2,iframe2</keywords>

    </portlet-info>

  </portlet>

 

3、  配置对应的.psml文件,如下:

<fragment id="sample-335577" type="layout" name="jetspeed-layouts::VelocityTwoColumns">

    <fragment id="sample-3355771" type="portlet" name="sample::EchoIframe">

      <property layout="TwoColumns" name="row" value="0" />

      <property layout="TwoColumns" name="column" value="0" />

    </fragment>

    <fragment id="sample-3355772" type="portlet" name="sample::EchoPortlet">

      <property layout="TwoColumns" name="row" value="0" />

      <property layout="TwoColumns" name="column" value="1" />

    </fragment>

  </fragment>

 

 

 

3、

jetspeed2的登陆权限验证完全居于JAAS,其配置文件是在jetspeed应用lib库中的jetspeed-security-<version>.jar中的login.conf文件中定义的,如果想替换成自己的验证模式,可以修改此配置文件,如下:

Jetspeed {

   org.apache.jetspeed.security.impl.DefaultLoginModule required;

};

请注意,自己加的login.conf配置文件可以放在WEB-INF/classes目录下的任何位置,并且修改WEB-INF/assembly目录下的security-providers.xml文件相应的login.conf文件的新位置。

4、

JAAS的subject主要用来表示一个应用主体对象(用户),此对象有一个或多个用来标识其身份的Principals,如名字(name principal)或者身份证号(SSN principal),principal是用来唯一标识此subject,以区别于其他的subject的。原文如下:

To authorize access to resources, applications first need to authenticate

the source of the request. The JAAS framework defines the termsubject

to represent the source of a request. A subject may be any entity, such

as a person or a service. Once the subject is authenticated, a

javax.security.auth.Subject is populated with associated identities, or

Principals. A Subject may have many Principals. For example, a person may

have a name Principal ("John Doe") and a SSN Principal ("123-45-6789"),

which distinguish it from other subjects.
