Best Practice: WebSphere plug-in configuration regeneration
For a Web server to direct servlet requests to a servlet container on the application server, certain plug-in configuration files must be set correctly. If updates to the WebSphere Application Server configurations are made, the WebSphere Application Server must be stopped and restarted or manual regeneration of the plug-in config files must occur so that the plug-in can direct servlet requests correctly. In most large production sites, it is best to manually create the Web Server plug-in. There is a WebSphere property that allows you to disable automatic regeneration of the config files, but you must understand the implications of doing so.

Best Practice: Not creating HttpSessions in JSPs by default
Do not create HttpSessions in JSPs by default. JSPs create HttpSessions by default. If you do not need an HttpSession, you can enhance performance by simply not taking the default with a one line JSP directive. Lab measurements have yielded a 5% performance throughput when this default is not used.

Best Practice: Closing and releasing JDBC resources
Close and release JDBC resources when finished using them. Ensure that they are closed/released in all circumstances, including exceptions and errors. JDBC connection pooling provides a defined and finite number of JDBC connections. Shortages cause long waits. Failing to close JDBC connections causes waits for idle JDBC connections to be reaped and reused. Closing JDBC connections will allow quicker reuse and improve performance.

Best Practice: Using Open Servlet Engine (OSE) Remote
When configuring how requests are passed from the HTTP server to the WebSphere Application Server in a DMZ, you should consider ease of configuration, available security, and speed of execution when choosing an option for a specific environment. OSE Remote offers easy configuration, greater security, and better performance over alternatives such as "Thin" and "Thick" servlet redirectors.

Best Practice: Storing objects in HTTP sessions
Do not store large object graphs in HttpSession. This can severely affect the performance of a WebSphere application. Look for alternatives like an application specific JDBC framework that can augment or replace HttpSession for storing servlet state data. Application design for performance and scalability requires consideration of servlet state data. If your application requires a large amount of servlet data, consider application specific alternatives that either augment or replace the use of HttpSession.

Best Practice: Classpath structure for WebSphere Application Server
The WebSphere Application Server static system classpath structure is designed for stable packages that the application server uses frequently. The static system classpaths are searched first, followed by the dynamic classpaths. There are two different types of dynamic classpaths: Web Application classpath and Node Dependent classpath. The dynamic classpaths are structured to reflect packages that are subject to change. Classes that are stable and do not frequently change should be placed in the static classpath, whereas classes that are frequently changed should be placed in the dynamic classpath.

Best Practice: Releasing and invalidating HTTP sessions
Invalidate and release HttpSession objects when you are finished with them. WebSphere allows for a user-configured finite number of HttpSessions. WebSphere can reuse an HttpSession when the application invalidates it or when WebSphere re-claims it after a user-configured idle timeout period. While you can exceed this number, invalidating and releasing HttpSessions will provide for better performance.

Best Practice: Using HttpServlet init method
If a servlet has a one-time and expensive operation, incorrect coding techniques can lead to degraded performance. Use the HttpServlet init method to perform one-time expensive operations, such as acquiring thread-safe resource acquisition mechanisms. The overall performance impact significantly reduces when using the HttpServlet init method as the init method is only called once when the servlet is loaded.

Best Practice: Using JDBC connection pooling
To avoid the overhead of acquiring and closing JDBC connections, WebSphere Application Server provides JDBC connection pooling based on JDBC 2.0. Servlets should use WebSphere Application Server JDBC connection pooling instead of acquiring these connections directly from the JDBC driver. WebSphere Application Server JDBC connection pooling involves the use of javax.sql.DataSources.

Best Practice: Designing applications with EJBs
When designing applications and considering the use of Enterprise JavaBeans (EJBs), you can choose from a number of options. These options offer different levels of complexity, advantages, and disadvantages. Based on the Model-View-Controller (MVC) architecture, a session bean can be used as a facade to an entity bean, providing increased performance by reducing the number of network calls. Besides performance improvements, the facade session bean hides the complexity of EJBs leading to separation of presentation logic and business logic.

Best Practice: Using string concatenation with Java
Exercise extra caution when choosing a technique for string concatenation in Java programs. Simply using the "+=" operator to concatenate two strings creates a large number of temporary Java objects, since the Java String object is immutable. This can lead to poor performance (higher CPU utilization) since the garbage collector has additional objects to collect. Use the Java StringBuffer object to concatenate strings because it is more efficient.

Best Practice: Accessing EJB entity beans from EJB session beans
Use EJB session beans to access EJB entity beans. By wrapping entity beans with session beans, you can achieve better performance. This enforces the sound object model concept of wrapping passive data entity objects by active process objects. An EJB client, however, can be written to access an entity bean directly, but there is a performance cost in doing so. The best performance is obtained by wrapping entity beans with session beans.

Best Practice: Using pass by reference for EJBs and servlets if in same JVM
Use the "Pass By Reference" call semantics to avoid RMI-IIOP overhead involving EJB and other application components in the same JVM. The EJB 1.1 specification states that method calls are to be "Pass By Value." This means that for every remote method call, the parameters are first copied onto the stack before the call is made. However, this operation can be expensive. By specifying "Pass By Reference," the original object reference is passed without a copy being made. This can result in a significant performance improvement.

Best Practice: Do not use Beans.instantiate() to create new bean instances
Using Beans.instantiate() can have an adverse performance impact because this method will search fora serialized version of that object on the file system. If a serialized object is found, it is loaded. If it is not found, the object is created.

Best Practice: Removing stateful session beans
When an Enterprise Java Bean (EJB) client no longer needs a stateful session bean, the client should explicitly remove it from the container. By doing so, applications can decrease the need for passivation, minimize container overhead, and provide an increased level of performance. If they are not explicitly removed, resources are consumed by the container managing many stateful session beans.

Best Practice: Using java:comp and the DB2 Connect Gateway for portable database applications
Many WebSphere applications must access a DB2 database. When developing for WebSphere on zOS, the typical development scenario involves developing and unit testing an application in WebSphere Studio Application Developer and then redeploying to WebSphere Application Server for z/OS and OS/390. When the deployed application being developed must access data in a DB2 for zOS database, it is imperative that the development tool also access the database data on the zSeries machine. The best practice is to use the java:comp notation for accessing the DB2 datasources along with the DB2 Connect Gateway rather than hardcoding the database name and having to make changes when moving the application into production. Following this best practice will ease deployment to multiple platforms

Best Practice: Developing Web applications for WebSphere Simple Configuration Runtime
When developing Web applications for deployment on the WebSphere Simple Configuration runtime, be mindful of possible future deployments on the WebSphere Standard Configuration runtime. Even though your Web application is not targeted to execute in a J2EE Server (like WebSphere Application Server 4.0.1 Standard Configuration), developers can adopt techniques that will make their code easier to maintain today and simpler to move to a more advanced runtime in the future. If a Web application is developed solely for the WebSphere Simple Configuration runtime, an application may have to be re-designed for deployment on a fully compliant J2EE Server.
