JSP and JSF option settings

Use this panel to configure the class reloading of Web modules such as JavaServer Pages (JSP) files and to select a JSF implementation to use with this application.

To view this administrative console panel, click Applications > Application Types > WebSphere enterprise applications > application_name > JSP and JSF options. This panel is the same as the Provide JSP reloading options for Web modules panel on the application installation and update wizards.

Web module

Specifies the name of a Web module in the installed or deployed application.

URI

Specifies the location of the module that is relative to the root of the application (EAR file).

JSP enable class reloading

Specifies whether to enable class reloading when JSP files are updated.

A Web container reloads JSP files only when the IBM® extension reloadEnabled in the jspAttributes of the ibm-web-ext.xmi file is set to true.

Supported configurations: For IBM extension and binding files, the .xmi or .xml file name extension is different depending on whether you are using a pre-Java EE 5 application or module or a Java™ EE 5 or later application or module. An IBM extension or binding file is named ibm-*-ext.xmi or ibm-*-bnd.xmi where * is the type of extension or binding file such as app, application, ejb-jar, or web. The following conditions apply:

However, a Java EE 5 or later module can exist within an application that includes pre-Java EE 5 files and uses the .xmi file name extension.

The ibm-webservices-ext.xmi, ibm-webservices-bnd.xmi, ibm-webservicesclient-bnd.xmi, ibm-webservicesclient-ext.xmi, and ibm-portlet-ext.xmi files continue to use the .xmi file extensions.

sptcfg

JSP reload interval in seconds

Specifies the number of seconds to scan the application's file system for updated JSP files. The default is the value of the reloading interval attribute in the IBM extension (META-INF/ibm-web-ext.xmi) file of the Web module.

To enable reloading, specify a value greater than zero (for example, 1 to 2147483647). The default reload interval is 5. To disable reloading, specify zero (0). The range is from 0 to 2147483647.

The reloading interval attribute takes effect only if class reloading is enabled.

J2EE 5 applications IBM extension files are in .xml file format. For applications versions earlier than J2EE 5, they are in the .xmi file format.

Sun Reference Implementation 1.2

Select this option to use the Sun Reference Implementation 1.2 JSF implementation. This is the default JSF implementation.

If you change the JSF implementation that you are using for your application, you must delete any previously compiled JSP files. If you precompiled your application, you must recompile. If you did not precompile, but have already requested JSP files from this application, you must delete the JSP files from the temp directory of your profile.

You can set the JSF engine configuration paramater, com.ibm.ws.jsf.JSF_IMPL_CHECK, to true to automatically mark the JSP files to recompile at application startup.

MyFaces 1.2

Select this option to use the MyFaces 1.2 JSF implementation.

If you change the JSF implementation that you are using for your application, you must delete any previously compiled JSP files. If you precompiled your application, you must recompile. If you did not precompile, but have already requested JSP files from this application, you must delete the JSP files from the temp directory of your profile.

You can set the JSF engine configuration paramater, com.ibm.ws.jsf.JSF_IMPL_CHECK, to true to automatically mark the JSP files to recompile at application startup.
