Section of the IDE's Explorer window. The top level node shown is a J2EE application named CatalogApp. It has subnodes for an EJB module named CatalogData, which has the same subnodes as it did in the preceding figure;. The application also has a subnode for a web module named CatalogWebModule. The web module looks different than it did in the figure that shows the web module. In the earlier figure, CatalogWebModule appeared as a filesystem named CatalogWebModule. In this figure it appears under the application node as a logical node. In the earlier figure, the web components, AllItemsServlet and ItemDetailServlet were shown in the web module's directory structure. Here they appear as logical nodes directly under the web module node.
