Application development tools
This chapter describes the various application development tools that come with this configuration of WebSphere Studio.
Java development tools
The Java development tools included with WebSphere Studio support the development of any Java application. They add Java perspectives to the workbench as well as a number of views, editors, wizards, builders, and code merging and refactoring tools. The Java development tools offer the following capabilities:
JDK 1.3 support
Pluggable run-time support for JRE switching and targeting multiple run-time environments from IBM and other vendors
Automatic incremental compilation
One debugger for both local and remote debugging
Ability to run code with errors in methods
Crash protection and auto-recovery
Error reporting and correction
Java text editor with full syntax highlighting and complete content assist
Refactoring tools for reorganizing Java applications
Intelligent search, compare, and merge tools for Java source files
Scrapbook for evaluating code snippets
Java projects and incremental compilation
WebSphere Studio features a Java project structure which has an associated Java builder incrementally compile Java source files as they are changed. Each Java project maintains additional information about the type hierarchy and the references and declarations of Java elements. This information is constantly updated as the user changes the Java source code; it is not dependent on the builder.
Perspectives, views, and editors
WebSphere Studio includes the Java and Debug perspectives to organize resources for Java editing or debugging. The Java perspective provides views, wizards, preferences and property sheets for creating, viewing, and editing Java resources. The Java text editor features full syntax highlighting and complete content assist based on anything visible in the Java project's class path, including elements in the currently edited file. The Debug perspective features a debugger that can be used locally or remotely.
Configurable Java run-time environment and JDK level
You can add new JRE definitions to WebSphere Studio and switch between JDK levels. When installing a JRE, you can specify the JRE type, name, home directory, and the default library location. WebSphere Studio supports JDK 1.3 with the ability to configure multiple test environments.
Refactoring tools
Workbench Studio features refactoring tools for reorganizing Java applications. When you refactor a program, you transform your code while preserving its behavior. When refactoring, you can optionally preview all the impending changes resulting from a refactoring command before you finally choose to carry it out. You can rename an element, and the refactoring support changes both the selected resource's name and all references to it.
Scrapbook
The Java development environment contributes a facility that can be used to experiment and evaluate Java expressions (code snippets). Snippets are edited and evaluated in the Scrapbook page editor. You can select a code snippet, evaluate it, and display the result as a string or show the result object in the debugger's inspector.
Search tools
The Java development environment includes intelligent search tools for Java source files. The Java support allows you to precisely find declarations and references of Java elements (package, type, method, field). Searching is supported by an index that is kept up to date in the background as the resources corresponding to Java elements are changed.
For more information about the Java IDE, refer to the online help.
Visual Editor for Java
The Visual Editor for Java provides an interface to assist with visual construction of the user interface (UI) for a Java application or applet. It is based on the JavaBeans component model, and supports visual construction using either the Advanced Widget Toolkit (AWT) or Swing. The Visual Editor for Java comprises a tool palette, a design canvas, and a source pane. The design canvas displays a visual representation of the beans and the associated source is displayed in the source pane. As you modify the beans in the design canvas, the Java source is modified to reflect the change. The reverse is also true; as you make changes to the source, the design canvas is updated to reflect parsable changes. Not only can you generate your code, but you can immediately see the effect of source code modifications during development. You can make changes to your Java file in another editor and then open it again in the Visual Editor for Java; your changes will automatically be reflected in the Visual Editor for Java.
Web development tools
The Web development environment in WebSphere Studio provides the tools necessary to develop Web applications as defined in the Sun Microsystems Java Servlet 2.3 Specification and the Sun Microsystems JSP 1.2 Specification. Web applications include static Web pages, JavaServer Pages (JSPs), Java servlets, deployment descriptors (web.xml files), and other Web resources.
This environment brings all aspects of Web application development into a common interface. Everyone on your Web site team, including content authors, graphic artists, programmers, and Webmasters, can work on the same projects and access the files they need. Within the integrated Web development environment, it is easy to collaboratively create, assemble, publish, deploy and maintain dynamic, interactive Web applications.
The Web development environment includes the following high-level capabilities:
Web project creation, using either the J2EE-defined hierarchy or a static version that reduces project overhead when dynamic elements are not required.
Creation and editing of a Web deployment descriptor (web.xml) file
Site-level Web management templates and support
JSP and HTML file creation, validation, editing, and debugging
JavaScript editing and validation
Custom JSP tags (taglib) support, based on the JSP 1.2 specification
An extensible view, called the Library view, which allows users to catalog and organize reusable programming objects, such as HTML, JavaScript, and JSP code, along with files and tag libraries
Image editing and animation
Cascading Style Sheet (CSS) editing support
HTTP/FTP import
FTP export (simple resource copy) to a server
Web archive (WAR) file import, export, and validation
Link viewing, parsing, validation, and management, which includes converting links, flagging broken links, and fixing links as resources are moved or renamed
Servlet creation, by means of a wizard to create new servlets and add servlet mappings to the deployment descriptor (web.xml) file
Generation of Web applications using wizards that create Web resources from database (SQL) queries and beans
Integration with the WebSphere test environment
Publishing support for multiple Web server types
Web services development tools
WebSphere Studio provides wizards and other tools to enable rapid development of Web services. Web services are modular, standards-based e-business applications that businesses can dynamically mix and match to perform complex transactions with minimal programming. Web services allow buyers and sellers all over the world to discover each other, connect dynamically, and execute transactions in real time with minimal human interaction.
Some examples of Web services could be theatre review articles, weather reports, credit checks, stock quotations, travel advisories, or airline travel reservation processes. Each of these self-contained business services is an application that can easily integrate with other services, from the same or different companies, to create a complete business process. This interoperability allows businesses to dynamically publish, discover, and bind a range of Web services through the Internet.
The Web services development tools provided in WebSphere Studio are based on open, cross-platform standards:
Universal Description Discovery and Integration (UDDI), which enables businesses to describe themselves, publish technical specifications on how they want to conduct e-business with other companies, and search for other businesses that provide goods and services they need, all via online UDDI registries
Simple Object Access Protocol (SOAP), which is a standard for reliably transporting electronic business messages from one business application to another over the Internet
Web Services Description Language (WSDL), which describes programs accessible via the Internet (or other networks), and the message formats and protocols used to communicate with them
WebSphere Studio facilitates the following processes to assist with building and deploying Web services-enabled applications:
Discover. Browse the UDDI business registry to locate existing Web services for integration.
Create or Transform. Create Web services from existing artifacts, such as Java beans, EJB beans, URLs that take and return data, DB2(R) XML Extender calls, DB2 stored procedures, and SQL queries.
Build. Wrap existing artifacts as SOAP and HTTP GET/POST-accessible services and describe them in WSDL. The tools also assist you both in generating a SOAP and HTTP GET/POST proxies to Web services described in WSDL and in generating bean skeletons from WSDL.
Deploy. Deploy Web services in the WebSphere Application Server or Apache Tomcat test environments using Server Tools.
Test. Test Web services running locally or remotely in order to get instant feedback.
Develop. Generate sample applications to help you create your own Web service client application.
Publish. Publish Web services to the UDDI business registry, advertising your Web services so that other businesses can access them. |
