► Trace: Allows you to enable WebSphere tracing and to specify the output file. ► Security: Contains security settings for WebSphere security. Security is covered in Chapter 16, “Security” on page 551. ► Applications: Allows you to specify classloader mode and policy. 13.6.1 Classloaders and file location At runtime the server will need to be able to load the classes and JAR files used by the application. Classloaders are part of the JVM code and are responsible for finding and loading these files. The key to success is to understand how files are loaded and where to locate them for proper loading. In order to understand this, we suggest that you read J2EE Class Loading Demystified at: http://www7b.boulder.ibm.com/wsdd/library/techarticles/0112_deboer/ deboer.html Tip: If you are getting a ClassNotFoundException, it is time to read that article. For now, take the default classloader settings in the server configuration and use the following guidelines taken from this article: ► If your JAR file is only used in a single Web application, always put the JAR file in the Web project's Web Content/WEB-INF/lib folder. JAR files in this folder are automatically added to the Java build path, and will not require any further setup when moving to a different server. ► If the JAR file is used by multiple modules within the same application, put the JAR file in the enterprise application. You will need to use the Edit Module Dependencies feature to set up the manifest files and the Java build class paths. ► You can also put the JAR on one of the global class paths (using the Paths servlet configuration page), but we don't recommend this. It complicates your deployment and leaves your application vulnerable to incompatibility problems if those JARs are later upgraded. ► If you still want to put the JAR file on the global class path, you must decide whether it should go on the class path or ws.ext.dirs. If the JAR file needs to access any J2EE or WebSphere classes, or any other JARs that have been added to ws.ext.dirs, it must also be placed on the ws.ext.dirs property. Otherwise, you are free to use either property. ► If you have dependencies on the JAR file, update the Java build path of each project that uses the JAR file. Adding it to the global class path or ws.ext.dirs 486 IBM WebSphere Application Server - Express V5.0.2 Developer Handbook
properties also means that you will have to publish the JAR file separately from your application, and you will have to set up the server class path again when you move to a different server. 13.7 Server operations Servers can be started, stopped, published to, or restarted using the Server perspective. The Servers view shows the status of each server and allows you to control it. 13.7.1 Starting the server You can start a server from the Servers view by right-clicking the server project and selecting Start. When starting the server: ► If the Automatically publish before starting servers check box in the server preferences (Window -> Preferences) is selected, the Server tools feature checks to see if your project and files on the remote server are synchronized prior to starting the server. If they are not, the project and the files are automatically updated on the remote when the server is started. ► The Console view opens automatically and displays the messages as they occur. It will take a minute to start the server. ► A successful start is indicated by the Server server1 open for e-business message. In the Status column of the Servers view, the status of the server changes to Started. If the server fails to start, check the console for an indication of what might be wrong. Chapter 13.
