Figure 14-2 500 page error These error pages do not really provide you with any significant information, but they do point you in the correct direction. 500 errors can also be located using the Project navigator or Tasks views, but the Console view may be of more help. For more information about the Console view, see 14.1.5, “Console view” on page 499. 14.1.2 Project navigator view Errors and warnings on resources (including Java, HTML/JSP, and Links Builder errors and warnings) are indicated with a red error or yellow warning next to the resource with the error, as well as the parent folders all the way up to the project folder. For example, in Figure 14-3 on page 497, there is an error in FeaturedItemXMLServlet.java. This is indicated with an error icon for that file and the files above it in the hierarchy. 496 IBM WebSphere Application Server - Express V5.0.2 Developer Handbook Error message
14.1.3 Tasks view Figure 14-3 Project navigator view You can navigate to the resource using the Project navigator view and then double-click it to open it in its default editor. The editor can then be used to correct the warning or error. Each warning or error will have an entry in the Tasks view providing you with information about the problem, including the description, resource, resource folder, and line location. Double-clicking an item from the Tasks view opens the corresponding resource in its default editor at the line of code causing the problem. For additional information about the Tasks view, please refer to “Tasks view” on page 84. Chapter 14. Testing and debugging 497
