An example of a page template you will find in the library is shown in Figure 5-18 on page 110. Figure 5-18 Page template Page templates can be applied to a Web page in one of the following ways: ► By specifying the template when you use a wizard to create the page. This is true regardless of whether you are using the wizard from a navigation view, a tool bar or the Web Site Designer. ► By using the Web Site Designer. You can apply a template as you create pages or to existing pages as you add them to the Web Site Configuration. You can also apply or replace templates to pages already in the configuration. ► By using the Page Designer. With the page open, select Page -> Page Template. You can apply, replace, or detach the template. You also have the option of opening the template for modification. A default page template can be specified when you create a Web project. If you specify a default template, it will be automatically selected when are given the option in wizards to select a template for a page. 110 IBM WebSphere Application Server - Express V5.0.2 Developer Handbook
Page templates versus style sheets Though style sheets have not been discussed as of yet (see 5.1.9, “Working with style sheets” on page 120), there may be some confusion about page templates and style sheets. Page templates are used if you wish to create a standard layout for the JSP and HTML pages in your application. For example, you may want each page in your application to have a header, a navigation menu on the left side of the page, and a footer. All of these elements can be created in a page template and then used by the pages in your application; this obviously will aid in the maintenance of your application as changes only need to be made in one area. Style sheets, on the other hand, are used by page templates (or JSP and HTML pages) to set fonts, colors, table formatting, etc. Again, like page templates, maintenance is done in one area, which will save time. A page template can act as a style sheet if you set your styles within the page template. Since the template is used by every page in your site, any settings in the page template will be reflected in the corresponding pages. That said, this is not the recommended development scenario. It is best to keep the page template and style sheet separate. Creating a page template To create a page template that you can use in Page Designer, follow these steps: 1. Create a new dynamic Web project: a. Choose File -> New -> Project. b. Select Web -> Dynamic Web Project and click Next. c. Enter a Project name and click Finish. 2. Create a JSP, an HTML, or an XHTML file. If you are creating a JSP file, follow these steps: a. Select the newly created project in the Project Navigator. b. Choose File -> New -> JSP File. The New JSP File wizard appears. c. Fill in the Folder and the File Name fields. d. Select HTML as the Markup language and None as the Model. e. Click Finish. The new page opens in Page Designer. 3. If you are creating an HTML or XHML file instead of a JSP file, follow these steps: a. Select the newly created project in the Project Navigator. b. Choose File -> New -> HTML/XHTML File. The New HTML File wizard appears. c. Fill in the Folder and the File Name fields. Chapter 5. Working with HTML 111
