File serving
In file serving, web applications can serve static file types, such as HTML. File-serving attributes are used by the servlet that implements file-serving behavior.
The file-serving behavior is implemented by setting the fileservingenabled property to true when configuring the web module.
Example attributes:
- bufferSize
- Sets buffer size that is used for serving static files.
- extendedDocumentRoot
- Enables you to configure an application with one or more directory
paths from which you can serve static files and Java ServerPages (JSP)
files. You can use this attribute when an application requires access
to files that exist outside of the application web application archive
(WAR) directory. For example, if several applications require access
to a set of common files, you can place the common files in a directory
to which you can link each application as an extended document root
directory.
Use this attribute in addition to the contextRoot attribute.
You can also use this attribute to define a WebSphere variable on multiple nodes to the appropriate directory.
Example:<fileServingEnabled="true">
where MY_CUSTOM_VARIABLE is the WebSphere variable that you want to define on multiple nodes.<fileServingAttributes xmi:id="FileServingAttribute_1" name="extendedDocumentRoot" value="${MY_CUSTOM_VARIABLE}"/>
For more information, see JSP engine configuration parameters.
