| PortletVelocityResult | | public class PortletVelocityResult extends WebWorkResultSupport (Code) | |
Using the Servlet container's
JspFactory , this result mocks a JSP
execution environment and then displays a Velocity template that will be
streamed directly to the servlet output.
This result type takes the
following parameters:
- location (default) - the location of the template to process.
- parse - true by default. If set to false, the location param
will not be parsed for Ognl expressions.
This result follows the same rules from
WebWorkResultSupport .
Example:
<!-- START SNIPPET: example -->
<result name="success" type="velocity">
<param name="location">foo.vm</param>
</result>
<!-- END SNIPPET: example -->

| Method Summary | |
| protected Context | createContext(VelocityManager velocityManager, OgnlValueStack stack, HttpServletRequest request, HttpServletResponse response, String location)
Creates the VelocityContext that we'll use to render this page. | | public void | doExecute(String location, ActionInvocation invocation)
| | public void | executeRenderResult(String finalLocation, ActionInvocation invocation)
Creates a Velocity context from the action, loads a Velocity template and
executes the template. | | protected String | getContentType(String templateLocation)
Retrieve the content type for this template. | | protected String | getEncoding(String templateLocation)
Retrieve the encoding for this template. | | protected Template | getTemplate(OgnlValueStack stack, VelocityEngine velocity, ActionInvocation invocation, String location, String encoding)
Given a value stack, a Velocity engine, and an action invocation, this
method returns the appropriate Velocity template to render. |
| createContext | | protected Context createContext(VelocityManager velocityManager, OgnlValueStack stack, HttpServletRequest request, HttpServletResponse response, String location)(Code) | | Creates the VelocityContext that we'll use to render this page.
Parameters:
velocityManager - a reference to the velocityManager to use
Parameters:
stack - the value stack to resolve the location against (when parseequals true)
Parameters:
location - the name of the template that is being used the a minted Velocity context. |
| executeRenderResult | | public void executeRenderResult(String finalLocation, ActionInvocation invocation) throws Exception(Code) | | Creates a Velocity context from the action, loads a Velocity template and
executes the template. Output is written to the servlet output stream.
Parameters:
finalLocation - the location of the Velocity template
Parameters:
invocation - an encapsulation of the action execution state.
throws:
Exception - if an error occurs when creating the Velocity context,loading or executing the template or writing output to theservlet response stream. |
| getContentType | | protected String getContentType(String templateLocation)(Code) | | Retrieve the content type for this template. People can override
this method if they want to provide specific content types for specific
templates (eg text/xml).
The content type associated with this template (default"text/html") |
| getEncoding | | protected String getEncoding(String templateLocation)(Code) | | Retrieve the encoding for this template. People can override this
method if they want to provide specific encodings for specific templates.
The encoding associated with this template (defaults to the valueof 'webwork.i18n.encoding' property) |
| getTemplate | | protected Template getTemplate(OgnlValueStack stack, VelocityEngine velocity, ActionInvocation invocation, String location, String encoding) throws Exception(Code) | | Given a value stack, a Velocity engine, and an action invocation, this
method returns the appropriate Velocity template to render.
Parameters:
stack - the value stack to resolve the location again (when parseequals true)
Parameters:
velocity - the velocity engine to process the request against
Parameters:
invocation - an encapsulation of the action execution state.
Parameters:
location - the location of the template
Parameters:
encoding - the charset encoding of the template the template to render
throws:
Exception - when the requested template could not be found |
