This topic highlights Web sites and other ideas for finding best practices for designing WebSphere® applications, particularly in the realm of WebSphere extensions to the Java™ Platform, Enterprise Edition (Java EE) specification.
This topic describes obtaining an integrated development environment (IDE). Use Rational® products from IBM® to design, construct, and manage changes to applications for deployment on your WebSphere Application Server products.
To debug your application, you must use a development environment like the IBM Rational Application Developer for WebSphere to create a Java project. You must then import the program that you want to debug into the project.
Application assembly consists of creating Java Platform, Enterprise Edition (Java EE) modules that can be deployed onto application servers. The modules are created from code artifacts such as Web application archive (WAR) files, resource adapter archive (RAR) files, enterprise bean (EJB) JAR files, and application client archive (JAR) files. This packaging and configuring of code artifacts into enterprise archive (EAR) modules or stand-alone Web modules is necessary for deploying the modules onto an application server.
Class loaders are part of the Java virtual machine (JVM) code and are responsible for finding and loading class files. Class loaders enable applications that are deployed on servers to access repositories of available classes and resources. Application developers and deployers must consider the location of class and resource files, and the class loaders used to access those files, to make the files available to deployed applications. Class loaders affect the packaging of applications and the runtime behavior of packaged applications of deployed applications.
Deploying an enterprise application file consists of installing an application file on a server configured to hold installable Java Platform, Enterprise Edition (Java EE) modules.
The application management support in WebSphere Application Server provides functions, such as installing and uninstalling applications, editing of binding information for installed applications, updating the entire application, and exporting the application. This functionality is provided through the com.ibm.websphere.management.application.AppManagement interface, which is exposed as a JMX-based AppManagement MBean, and can be accessed using code running on the server, or in a standalone administrative client program.
You can use the common deployment framework to add additional logic to application management operations. The additional logic can do such tasks as code generation, configuration operations, additional validation, and so on. This topic demonstrates, through programming, how to plug into the common deployment framework to extend application management operations.
Deploying a business-level application consists of creating the business-level application on a Version 7.0 or later server.
You can use the command framework programming to create, edit, update, start, stop, delete, export, import, and query information about business-level applications. A business-level application defines an enterprise-level application.
You can add logging and tracing to applications to help analyze performance and diagnose problems in WebSphere Application Server.
When you are having problems deploying an application, perform some basic diagnostics and verify your system's configuration to solve the problem.

This page provides a starting point for finding information about the use of asynchronous messaging resources for enterprise applications with WebSphere® Application Server.
This page provides a starting point for finding information about naming support. Naming includes both server-side and client-side components. The server-side component is a Common Object Request Broker Architecture (CORBA) naming service (CosNaming). The client-side component is a Java™ Naming and Directory Interface (JNDI) service provider. JNDI is a core component in the Java Platform, Enterprise Edition (Java EE) programming model.
