5. You have three options for proceeding: a. If you want to accept the defaults associated with a new JSP file, leave Model as None and make sure the Configure advanced options is unchecked. b. If you want to apply a page template to your new file, select Page Template in the Model field and click Next. i. If you want to use one of the sample templates provided, select Sample Page Template and then choose one of the templates shown in the Thumbnail box. ii. If you want to use a template of your own, select User-defined Page Template and then click Browse to select the template from the file system. c. If you want to specify or customize the file options, select the Configure advanced options check box and click Next. i. You can add tag libraries from a variety of sources by clicking the Add button to locate a TLD file or a JAR file that contains a TLD file. Tag library Universal Resource Identifier (URIs) can be located in one of the following places: Defined in the web.xml file Within a JAR file located in the project lib directory that contains /META-INF/taglib.tld Within a JAR file external to the project In a “loose” TLD anywhere in the project As you add tag libraries, the Available Custom Tags window displays the declaration of the tag along with the tag library directive. If the selected TLD file hasn't been registered in the web.xml file, it will be added automatically. ii. In the Select a tag library dialog, either select one of the available tag libraries or click the Import button to locate and add a tag library to the list, and then select it. The dialog will automatically populate the informational fields that describe the tag library and its contents. You must specify a Prefix value. Click OK to add the tag library. iii. Click Next. iv. If you want to select an encoding type, deselect the Use workbench encoding check box to select a new encoding attribute. Select the appropriate encoding value to add to the file's HTML declaration from the Encoding drop-down list. The default is the value set in the HTML Files preferences page, which is accessed by selecting Window -> 264 IBM WebSphere Application Server - Express V5.0.2 Developer Handbook
Preferences, and then expanding the Web and XML Files preferences. v. Ensure that the proper content type is selected in the Content Type drop-down list. The default depends on the markup language. vi. Select the Document Type that you wish to associate with the JSP file. The default depends on the markup language. vii. Specify a cascading style sheet (CSS) file to to be referenced by the new JSP file. Typically, CSS files are located in the theme folder under the WebContent folder. You can use Add to choose a style sheet from the file system. Use Remove to delete a style sheet from the list, or use the arrow buttons to rearrange the order in which the file references the style sheets. If a style sheet is already associated with the project in which you are creating the new file, that style sheet is the default. viii.Click Next to select specific method stubs and add deployment information to the Web project's web.xml file. Select any appropriate method stubs to be created in the servlet that is deployed for this JSP file. If you select the Add to web.xml check box, the JSP file, along with its display name, and any URL mappings and initialization parameters associated with the JSP file will be automatically included in the Web project deployment descriptor file. Note that the File Name value provided in the first page of the wizard is automatically mapped to the Servlet Name value on this page, as well the URL Pattern mappings. These mappings are not updated if you change the original value in the File Name field. 6. Click Finish to create the file in the project that you have selected. As a default, the new file opens in Page Designer, in the Design page. 8.3 Using JSPs in the Online Catalog sample Now that you have seen some of the aids, try using them to build a JSP. Much of the coding that you do will probably end up to be straight typing, but remember that there are many aids to ease the process. It will take practice to become familiar with what is available.
