public interface LoadAssemblyTag
jspTags
  produces: HTML
 This tag emits the files listed under a single FileAssemblyEntry in your FileAssembly
 config file.  Note that as stated in the FileAssembly docs,
 you can always include a
  file assembly by writing out a properly formatted <script> or <link> HTML tag
  and referencing the same URI as listed in the FileAssemblyEntry that you wish to include,
  but the <loadAssembly> JSP tag provides a useful mechanism to easily switch between
  development and production mode (via the assemble attribute - see below) as well as a
  few other control points.
  
Tag Attributes:
  URI
  value format: A URI that exactly matches one of the FileAsemblyEntry URIs in your
  FileAssembly configuration file.
  default value: NONE
  
This attribute selects the specific assembly that you wish to include from the file assembly config file and is required.
  assemble
  value format: boolean - acceptable values: "true" or "false"
  default value: "true"
  
This attribute controls the manner in which the files listed in your FileAssemblyEntry are emitted onto the page. When set to "true" (the default), the loadAssembly tag simply emits a <script> or <link> HTML tag (depending on the extension) and references the URI you specified. This is what you want for production deployment.
When set to "false", the loadAssembly tag emits separate <script> or <link> HTML tags for each file listed under the FileAssemblyEntry. This is what you frequently want for development because it allows browser tools like Firebug and native browser debuggers to properly report line numbers for errors in a manner that is easily traceable to the source file and location.
The recommended best practice is to parametrize the value of the assemble attribute based on the deployment target and use a rewrite mechanism either in your packaging script (e.g. Ant) or the deployment tool to conditionally set this value such that it is set to "false" in development and "true" in production. For example, like so with Ant:
assemble="<%=\"prd\" == \"@app.server.target@\"%>"Note that you then need corresponding logic in your Ant build.xml that does something like:
  <property name="app.server.target" value="prd"/>
  <replace file="${war.dir}/your.jsp" token="@app.server.target@" value="\${app.server.target}"/>
  
  
  locale
 value format: valid locale string - see DataSourceLocalization for more
  details and examples.
  default value: as set by the OS/JVM defaults
  
  media
 value format: any valid value of the media attribute of the HTML <link>
 element.
  default value: NONE
  
  This attribute is valid only for FileAssembly entries with a URI that ends with ".css".
  When set, the value of this attribute is output as the value of the media
  attribute of the <link> element that is emitted onto the page.  See
 e.g. http://www.w3schools.com/tags/att_link_media.asp for valid values of the
  media attribute and a discussion of when/how to use them.
  
  configFile
 value format: Path to FileAssembly configuration file
 exactly as it would be
  supplied to the servlet config via the configFile init-param.
 default value: Automatically derived from FileAssembly
 servlet configuration.
  
 This attribute enables an explicit override of the FileAssembly config file use to
  match the URI entries.  Providing this value is not required - it is auto-derived
 automatically from the settings you provide on the FileAssembly servlet.  But in rare
  instances (certain non-compliant servlet containers and/or extremely tight java security
  settings) this auto-derivation can fail and you can use this attribute to provide an
  explicit setting.
