This IBM redbook offers layout directions for constructing e-business functions according to servlets, JavaServer Pages (JSP) and firm JavaBean (EJB) applied sciences. the information are in keeping with WebSphere program Server complicated variation. The redbook describes the strategies of workload balancing by using a community dispatcher and clones of the applying Server. The redbook proposes a layout of net purposes in line with layout styles, reminiscent of the model-view-controller paradigm and the command framework. during this context, using firm beans, together with entry beans, institutions, and collections is explored intimately, and a suite of EJB-based layout styles is defined. half 1, "Choosing applicable internet technollogies" offers instructions on easy methods to layout particular parts of an program. It additionally explains why and while a dressmaker may still movement company good judgment from JavaBeans to a extra robust expertise like company JavaBeans. half 2, "Design styles and instructions" is a suite of layout styles for development e-business functions. Readers can use the data without delay from a bankruptcy and observe it of their personal designs

The command bean is used as before. Only the server knows about the server class and deserializes the server command bean instead of the client command bean. Chapter 4. WebSphere command framework 39 Figure 22. 4 Command target and server implementation An easy way to provide a target for executing commands in the same Java environment is the use of a local implementation. This is done by a local command manager which is just a Java class implementing the CommandTarget interface. The executeCommand() method calls the performExecute() method of the command bean.
Then, the command asks the target policy for a command target. If the default target policy is used, it uses the strategy described above. The policy creates a new command target; and the command calls the command target for execution by using the executeCommand() method. Since we are executing a targetable command, the command target copies the command to the server where its performExecute() method is called. If the command has output properties (which is determined by calling its hasOutputProperties() method), it is replicated back to the client side, where the original command copies its output properties from the replicated command with the setOutputProperties() method.
3 Servlets/EJB load balancing Requests, from servlets and/or EJBs, to EJBs, can be WLMed in the same kind of way. Basically what you do is the same: configure the application server you want to clone, deploy into it the enterprise beans that you plan to clone, create a model of the server and then use the server model for creating one or more new clones. The only tricky part is to use the "wlmjar" command against the deployed JAR file of the enterprise bean to produce a WLM-enabled JAR file (VisualAge for Java does that by default).
