WebSphere Portal 6平台porlet skin中获取portletID和porletTitle的方法

 

在portlet skin的Control.jsp中：

 

通过如下方式可获得portletID和portletTitle并输出到HTML中：

导入以下taglib

<%@ taglib uri = "http://www.ibm.com/xmlns/prod/websphere/portal/v6.0/portal-skin" prefix="portal-skin" %>

 

//获取portletID

<portal-skin:portletID />

 

//获取当前语言区域的portletTitle

<portal-skin:portletTitle>

      <portal-fmt:problem bundle="nls.problem" />

</portal-skin:portletTitle>

 

 

通过如下方式可获得portletID和portletTitle并将他们赋值给某个Java变量：

//获取portletID并赋值

<portal-skin:portletID var="myPortletID"/>

<jsp:useBean id="myPortletID" class="java.lang.String" scope="page"/>

<%

      //赋值后便可以使用了

      String s = myPortletID;

%>

 

//获取默认语言区域（EN）的portletTitle并赋值

<portal-skin:portletTitle id="myPortletTitle"/>

次标签将编译成：

String myPortletTitle = doSomeThingAndGetCurrentPortletTitle();

通过如下方法可以编程获得porletTitle：

 

<%!
private static com.ibm.portal.identification.Identification identification;
public void jspInit(){
    try{
        /* only perform this JNDI lookup once as this is an expensive call performance wise */
        javax.naming.Context ctx=new javax.naming.InitialContext();
        identification=(com.ibm.portal.identification.Identification) ctx.lookup("portal:service/Identification");
    } catch (javax.naming.NamingException ne){
        ne.printStackTrace();
    }
}
%>
<%
//Fetch currentLayoutNode
String currentLayoutNodeStr = "";
LayoutNode currLayoutNode = null;
if (pageContext.getAttribute("currentLayoutNode", pageContext.REQUEST_SCOPE) != null) {
    currLayoutNode=(LayoutNode)pageContext.getAttribute("currentLayoutNode", pageContext.REQUEST_SCOPE);
    currentLayoutNodeStr=identification.serialize(currLayoutNode.getObjectID());
} else {
    currLayoutNode=(LayoutNode)pageContext.getRequest().getAttribute("com.ibm.wps.composition.element");
    currentLayoutNodeStr=identification.serialize(currLayoutNode.getObjectID());
}

// Fetch Portlet Title
String currentNodeTitle = "";
com.ibm.portal.content.LayoutControl lControl = 
    (com.ibm.portal.content.LayoutControl) currLayoutNode;
com.ibm.portal.ObjectID portletDefOID = null;
    
try {
    javax.naming.Context ctx2 = new javax.naming.InitialContext();
    com.ibm.portal.model.LocalizedStringResolver localizedStringResolver = 
        (com.ibm.portal.model.LocalizedStringResolver) ctx2.lookup("portal:service/model/LocalizedStringResolver");

    currentNodeTitle = localizedStringResolver.getTitle(lControl, request.getLocales());
} catch (javax.naming.NamingException ne){}
