The portlet accesses a resource bundle from the getResourceBundle(Locale locale) method on the PortletConfig interface. For the portlet s purposes, it does not matter whether the information was specified in the portlet deployment descriptor or the resource bundle. If the information is not found in the specified resource bundle, the portal container will use the values defined in the portlet deployment

Sys.Services.ProfileService.properties.Property1 = document.form1.txtP1.value; Sys.Services.ProfileService.properties.Property2 = document.form1.txtP2.value; Sys.Services.ProfileService.save(null, OnProfileSaveCompleted, null, null);

descriptor. If there is no resource bundle, the portlet container will create one from the inline portlet information values.

defines the data structure members (in this case, Name and Members) used later in the method by the foreach loop to set up the groups:

public java.util.ResourceBundle getResourceBundle(java.util.Locale locale)

Summary

There are three standard pieces of metadata in the first version of the portlet specification: title, short title, and keywords. Expect more to be added in the future as the specification evolves. The resource bundle keys and a description are listed here: javax.portlet.title: The title to be displayed in the portlet s title bar and other places in the portal GUI. javax.portlet.short-title: This is a shorter version of the title for use on truncated displays. javax.portlet.keywords: The keywords are a comma-separated list of words or phrases that describe the portlet. The keywords can be used in a portlet catalog so the user can find the appropriate portlet. Here is an example showing the use of the resource bundle from a portlet:

foreach (var g in myGroups) { // implicit typing allGroups.Add(g.Name,new List <string>( )); foreach (string filename in g.Members) { allGroups[g.Name].Add(filename); album[filename].Load(filename); } }

In this chapter, you looked at how the AJAX extensions for ASP.NET handle scripts and services. You looked at the ScriptManager component in some detail, looking at how to handle partial page updates and errors in partial page updates, before moving on to managing custom JavaScript libraries using the ScriptManager control. You then went into some detail on accessing the web services using the ScriptManager and how Ajax uses JavaScript Object Notation (JSON) to provide script-based proxies to web services. Finally, you looked at ASP .NET authentication, membership, and profiling, and how the AJAX extensions provide services that allow the JavaScript developer to access their information. In the next chapter, you ll see how the AJAX extensions beef up the JavaScript developer s toolbox through object-oriented extensions and more.

package com.portalbook.portlets; import java.io.IOException; import java.io.Writer; import java.util.Locale; import java.util.ResourceBundle; import javax.portlet.GenericPortlet; import javax.portlet.PortletException; import javax.portlet.RenderRequest; import javax.portlet.RenderResponse; public class ResourceBundlePortlet extends GenericPortlet { protected void doView(RenderRequest request, RenderResponse response) throws PortletException, IOException { response.setContentType("text/html"); Writer writer = response.getWriter(); writer.write("<H2>Resource Bundle Values</H2>");

The flyweight activity happens in the last line, where album is accessed with a given filename and either returns an existing shared flyweight object or creates one and then returns it. The Load method is then called on this object, which is of type IFlyweight.

SP .NET AJAX offers many extensions to JavaScript, providing object-oriented features such as namespaces, inheritance, interfaces, enumerations, and more. These functionalities assist you in developing applications by providing more robust and structured language features, making it easier to maintain and add new features to your applications. In this chapter, you ll look at these extensions to JavaScript, starting with the objectoriented extensions, and then moving into some of the data type extensions, including arrays, Booleans, and dates.

//get the current Locale Locale locale = request.getLocale(); //get the Resource Bundle ResourceBundle rb = getResourceBundle(locale); //get the title String title = rb.getString("javax.portlet.title"); //get the short title String shortTitle = rb.getString("javax.portlet.short-title"); //get the keywords String keywords = rb.getString("javax.portlet.keywords"); //Output the title, short title, and keywords writer.write("Title: " + title + "<P>"); writer.write("Short title: " + shortTitle + "<P>"); writer.write("Keywords: " + keywords + "<P>"); } }

With respect to arrays in C# 2.0, only the length could be inferred from the simple form of array initializer. Implicit typing has since been extended to arrays so that both the element type and the length are inferred from the expression, as in:
