jetspeed开发实战

jetspeed开发实战

这里假设monsys为web服务的名称，其路径在webapps/下面
1,jetspeed的图片处理图片默认放在monsys/images下面，
调用方法：$clink.setURI("images/test.jpg")
2,javascript处理 javascript默认放在monsys/javascript下
调用方法：$clink.setURI("javascript/test.css")
3,portlets的位置位于monsys/WEB-INF/templates/vm/portlets/html下面
4,页面总体布局控制看JetspeedResources.properties
bottomnav.enable=true
bottomnav.vm=bottom.vm
leftnav.enable=true
leftnav.vm=left.vm
leftnav.width=10%
topnav.enable=true
topnav.vm=top.vm
topnav.logo.file=images/jetspeed-logo-1.5.gif
topnav.logo.url=
topnav.user_login.enable=true
topnav.user_creation.enable=true
topnav.my_pages.enable=true
5,portlets源代码分析: portlet主要实现三个方法:
<1>,buildMaximizedContext最大化
<2>,buildConfigureContext显示信息
<3>,buildNormalContext正常情况,也就是所看到的正常显示时所要显示的信息
<4>,调用时，在添加模块时添加新参数action=portlets.GraphDailyAction
package org.apache.jetspeed.modules.actions.portlets;
import .............(N个,略)
public class GraphDailyAction extends VelocityPortletAction {
/**
* Subclasses should override this method if they wish to
* build specific content when maximized. Default behavior is
* to do the same as normal content.
*/
protected void buildMaximizedContext(VelocityPortlet portlet, Context context, RunData rundata) {
buildNormalContext(portlet, context, rundata);
String text = (String) context.get("text");
if (text == null) {
text = "Top Record of baccarat game";
}
context.put("text", text + " (Maximized !)");
}
/**
* Subclasses should override this method if they wish to
* provide their own customization behavior.
* Default is to use Portal base customizer action
*/





protected void buildConfigureContext(VelocityPortlet portlet, Context context, RunData rundata) {
buildNormalContext(portlet, context, rundata);
setTemplate(rundata, "hello-customize");
}
/**
* 这是主要部份
* Subclasses must override this method to provide default behavior
* for the portlet action
*/





protected void buildNormalContext(VelocityPortlet portlet, Context context, RunData rundata) {
String mode = portlet.getPortletConfig().getInitParameter("mode"); //读取添加模块时从配置文件传来的参数
String searchdate = rundata.getParameters().getString("searchdate"); //取得从页面提交得到的参数
context.put("mode", mode);
context.put("searchdate", searchdate) //输出页面要显示的信息,支持输出数组，对像，及容器等形式的数据
}
}

<5>写好源代码，并编译，参考里的：　　
1,<3>所建的参数action,其值为portlets.GraphDailyAction，则系统会去执行这个类
