Web Application Rendering Component - Configuration Reference

A Rendering component defines how an application is rendered for delivery via the Web to the front-end client.

WEB_APPLICATION_RENDERING_COMPONENT

The WEB_APPLICATION_RENDERING_COMPONENT element specifies the output driver and other elements that determine how an application is to be rendered for a Web application. It takes an attribute Id, which specifies the unique identifier for this Rendering component. It is this unique identifier that is referenced by an application, specifying the output driver that the application should use.

Syntax

<WEB_APPLICATION_RENDERING_COMPONENT Id="compId">
  [ <OUTPUT_DRIVER> outputDriver </OUTPUT_DRIVER> ]
  [ <XML_DECLARATION> xmlDec </XML_DECLARATION> ]
  [ <HTTP_RESPONSE_ENCODING Source="REQUEST|INLINE"> httpResponseEnc </HTTP_RESPONSE_ENCODING> ]
  [ <HTTP_REQUEST_ENCODING Source="REQUEST|INLINE"> httpRequestEnc </HTTP_REQUEST_ENCODING> ]
  [ <MIME_TYPE> mimetype </MIME_TYPE> ]
</WEB_APPLICATION_RENDERING_COMPONENT>

Notes

The WEB_APPLICATION_RENDERING_COMPONENT may contain the following child element (described below):

1. Zero or more OUTPUT_DRIVER element (optional).
2. Zero or one XML_DECLARATION element (optional).
3. Zero or one HTTP_RESPONSE_ENCODING element (optional).
4. Zero or one HTTP_REQUEST_ENCODING element (optional).
5. Zero or one MIME_TYPE element (optional).

Example

<WEB_APPLICATION_RENDERING_COMPONENT Id="cpn.rendering.gwc">
  <OUTPUT_DRIVER>GWC</OUTPUT_DRIVER>
  <HTTP_RESPONSE_ENCODING Source="INLINE">ISO-8859-1</HTTP_RESPONSE_ENCODING>
  <HTTP_REQUEST_ENCODING Source="INLINE">ISO-8859-1</HTTP_REQUEST_ENCODING>
  <MIME_TYPE>text/html</MIME_TYPE>
</WEB_APPLICATION_RENDERING_COMPONENT>

<WEB_APPLICATION_RENDERING_COMPONENT Id="cpn.rendering.gwc2">
  <OUTPUT_DRIVER>GWC2</OUTPUT_DRIVER>
  <HTTP_RESPONSE_ENCODING Source="REQUEST"/>
  <HTTP_REQUEST_ENCODING Source="REQUEST"/>
  <MIME_TYPE>application/xml</MIME_TYPE>
</WEB_APPLICATION_RENDERING_COMPONENT>

OUTPUT_DRIVER

The OUTPUT_DRIVER element specifies the output driver to be used. Valid values include:

• GWC2 - The GWC2 output driver specifies that the snippet-based rendering engine be used to render the application for GWC front-end clients.
• GWC - The GWC output driver specifies that the legacy rendering engine be used to render the application for GWC front-end clients.
• XSLT10 - This value specifies that the application be rendered in XML. Prior to the introduction of the snippet-based rendering engine, this driver was used to render applications bound for handheld devices.
• JFE36 - This value is for use with GDC and GJC Front End clients.

Usage Examples

  <OUTPUT_DRIVER>GWC</OUTPUT_DRIVER>
  <OUTPUT_DRIVER>GWC2</OUTPUT_DRIVER>
  <OUTPUT_DRIVER>XSLT10</OUTPUT_DRIVER>
  <OUTPUT_DRIVER>JFE36</OUTPUT_DRIVER>

XML_DECLARATION

Specifies if the xml declaration is present or not in the document response. This element only works with OUTPUT_DRIVER = GWC2 or OUTPUT_DRIVER = XSLT10.

Usage Examples:

  <XML_DECLARATION>TRUE</XML_DECLARATION>

HTTP_RESPONSE_ENCODING

• When "Source" attribute is "INLINE": use content of HTTP_RESPONSE_ENCODING and force http response encoding to this value
• When "Source" attribute is "REQUEST": use Accept-Charset http request header sent by User-Agent to determine http response encoding. Use UTF-8 if Accept-Charset is missing.

Usage Example

  <HTTP_RESPONSE_ENCODING Source="INLINE">ISO-8859-1</HTTP_RESPONSE_ENCODING>
or
  <HTTP_RESPONSE_ENCODING Source="REQUEST"/> 

Back to the top

HTTP_REQUEST_ENCODING

• When "Source" attribute is "INLINE": use content of HTTP_REQUEST_ENCODING to determine encoding used in http request
• When "Source" attribute is "REQUEST": use "_charset_" form field or Content-Type http request header sent by User-Agent to determine encoding used in http request. Use UTF-8 if "_charset_" form field or Content-Type http request are missing.

Usage Example

  <HTTP_REQUEST_ENCODING Source="INLINE">ISO-8859-1</HTTP_REQUEST_ENCODING>
or
   <HTTP_REQUEST_ENCODING Source="REQUEST"/>

MIME_TYPE

Set MIME type in HTTP Content-Type response header. If not specified, the default MIME_TYPE of "text/html" is used by the output driver.

Usage Examples:

  <MIME_TYPE>text/html</MIME_TYPE>
  <MIME_TYPE>text/xml</MIME_TYPE>
