Sharing session data

Websphere Session Sharing

In this section, we explore the following mechanisms for sharing session data in a heterogeneous environment Messaging publish subscribe Once again, when reading this section, it is important to keep in mind that while the solutions can be implemented, one has to consider whether it is desirable to do so, since the alternative is often to eliminate interoperability issues altogether by carrying out a migration from one technology stack to the other. In this scenario, illustrated in Figure 9-10,...

Creating the static HTML page

A static HTML page may be easily generated in WebSphere Studio Application Developer. The page must contain a form with the action attribute referencing the the ASP.NET Web application and have the proper variables for propagating data from one application to another. WebSphere Studio will help generate and verify the HTML produced. It will also verify links within the document. For example, if the WS2NETAvgCal cRedirector application did not exist within the current context, it would be...

Installing the Microsoft Iis Http plugin

The Microsoft IIS HTTP plugin can be installed as part of the WebSphere Application Server installation. The installation procedure for WebSphere Application Server is documented in the IBM Redbook IBM Application Server V5.0 System Management and Configuration, SG24-6195. To install the plugin, perform a custom install as described in the aforementioned redbook. When prompted for the features that you wish to install under the Web Server Plugins category, select the Microsoft IIS plugin, as...

Service consumer NET consumer

Wpf Adorner

Our .NET consumer will be implemented as a fat client .NET assembly created in C in a similar manner to that used in previous scenarios. This assembly will use the MQ Classes for .NET to create a properly formatted request message and put it to a queue. Code will also be provided to obtain the response from the queue. 1. Create a new .NET solution. To do this, open Microsoft Visual Studio.NET and create a New Project. Use the Windows Application template from the New Project dialog so that we...

Load balancing and failover

Load balancing and failover capabilities under .NET come from the underlying and supporting technologies upon which it is built. Server clustering has been around since the days of NT and has been enhanced to provide additional features. With clustering, a multi-server Web application can provide service despite hardware failures on individual services. Although clustering is very powerful, it is a non-trivial implementation which must be properly planned in advance. Shared disk storage is...

URL redirection implementation

In keeping with the theme of the book, a simple calculator example was implemented to show a URL redirection solution between WebSphere Application Server and ASP.NET. The application is a simple calculator that takes two numbers, calculates the average, and returns the request to the client. This solution involves the following steps 1. Create a WebSphere application to process form data and the redirection request. 2. Generate a WebSphere static HTML page. 3. Publish the WebSphere HTML and...

URL redirection solution

The URL redirection solution, as shown in Figure 9-13 on page 403, shows the steps involved in using redirection to propagate data from an IBM WebSphere Web application to a ASP.NET application running on IIS. The steps involved to produce this interaction are as follows 1. The thin client requests a static page from the IBM HTTP Server. The server returns the page to the client. 2. The user enters data into the form and submits it back to the IBM HTTP Server. The server examines the URL and...

Consuming a Web Service in the business logic tier

The code and procedure for consuming a Web Service in a middleware component is the same as seen in previous samples. Figure 7-9 shows this scenario with a Windows client and a Web client. Figure 7-9 Consuming Web Service in the business logic tier using a .NET client The Windows client uses methods of the business logic, where the business logic invokes Web Services. This hides the actual implementation of the Web Service from the client. This scenario can be used with COM applications which...
