Caution: The message type functions are broken on several versions of the device software. If the previous example doesn t work on your particular platform, print out the value returned by getMessageType() for an incoming PIN message, and then change the code to test for that integer instead of for PIN_MESSAGE. Unfortunately, PIN messaging is not supported on the BlackBerry device simulator. I recommend using the Email Server Simulator and email messages for development on the simulator, then switch to PIN messages when running on the actual device. Most of your app logic should be able to remain the same, you will just switch between sending to a PINAddress instead of an Address, or switch whether you test for a PIN_MESSAGE type.

It s often necessary to convert string data between different formats. For example, files read using the ReadLine method on the System.IO.StreamReader type are read with respect to a Unicode encoding. You can specify this when creating the StreamReader; if left unspecified, the .NET libraries attempt to determine the encoding for you. One common requirement is to convert strings to and from ASCII representations, assuming that all the characters in the strings are in the ASCII range 0 to 127. You can do this using System.Text.Encoding.ASCII.GetString and System.Text.Encoding.ASCII.GetBytes. Table 10-8 shows the predefined encodings and commonly used members in the System.Text.Encoding type. Table 10-8. Types and Members Related to Unicode Encodings

Many production web-hosting environments use load balancers to distribute incoming client requests to available servers. Load balancers are especially useful to take one server at a time out of the pool for scheduled maintenance or upgrades. The load balancer uses cookies or another tracking method for HTTP requests and responses to ensure that each client s requests go to the same server. WSRP does not directly address details of load balancing and HTTP cookies for session tracking, but the consumer must return any cookies it receives. The producer may not have actually set the cookie on the HTTP response it could have been the load balancer. As a portlet developer, you will not have to do anything different for load balancing, but the portal administrator should make sure that the consumer portal is properly handling HTTP cookies on the WSRP SOAP request. This is very important to check when you do system or integration testing because the software vendors may not have tested your combination of consumer portal/load balancer/producer portal.

Note To make the flow between the three participants with different versions of the message possible,

The DockPanel control was first released in Silverlight 3 via the Silverlight Toolkit. It provides the ability to dock controls in all four directions: top, bottom, right, and left. Consider Figure 3-21, which is a possible layout with the DockPanel control involving five controls. The first two controls are docked in the left panel; the third control is docked in the top-center panel; the fourth control is docked in the bottom-center panel; and the fifth control is docked in the right panel.

Figure 9 8. Starting the Import Wizard 4. On the Application Settings page, verify the settings for your application, references, and resources, as shown in Figure 9 9. In the list of applications available for reference, specify any references your target application has to existing BizTalk application assemblies and artifacts. You can also specify a new application (labeled during the export) or associate with an existing application within your BizTalk Management database. Click Next to continue.

<servlet-mapping> <servlet-name>timesheet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> The timesheet application would probably be deployed to a context of /timesheet. The servlet mapping indicates that this servlet should correspond to paths in the root of this context. We would therefore invoke our servlet by requesting a path with the form http:// example.com/timesheet/. Any path below this one that does not already have an existing mapping will be translated into a call to the dispatcher servlet. Therefore, this path is also a call into our dispatcher: http://example.com/timesheet/admin. To determine exactly what behavior should be available on these paths, we need to create a mapping between paths and controllers.

We used Iskandar Salim s Lucene JSP tag library to display our results. You can download the tag library from its web page, www.javaxp.net/lucene-taglib. The Lucene tag library has an Apache Software Foundation 2.0 open source license. To use the tag library in this example, add the TLD definition file to the /tld directory under your WEB-INF folder, and add the taglibs-lucene.jar file to your WEB-INF/lib directory. There are three tags in the JSP tag library: <search>, <index>, and <field>. We are only going to use the <search> tag. The <search> tag provides us with an easy way to pass a query to an index. We defined the path to the index as a request attribute, so we retrieve it in the scriptlet at the top of the page. The JSP tag takes the name of the field to search as an attribute: field="contents". The <search> tag also takes an attribute for the analyzer, analyzer="standard", for the StandardAnalyzer class. The var attribute names the variable that holds the Hits object. The startRow and maxRow attributes
