@Deprecated
public class VelocityToolboxView
extends VelocityView

VelocityView subclass which adds support for Velocity Tools toolboxes and Velocity Tools ViewTool callbacks / Velocity Tools 1.3 init methods.

Specify a "toolboxConfigLocation", for example "/WEB-INF/toolbox.xml", to automatically load a Velocity Tools toolbox definition file and expose all defined tools in the specified scopes. If no config location is specified, no toolbox will be loaded and exposed.

This view will always create a special Velocity context, namely an instance of the ChainedContext class which is part of the view package of Velocity tools. This allows to use tools from the view package of Velocity Tools, like LinkTool, which need to be initialized with a special context that implements the ViewContext interface (i.e. a ChainedContext).

This view also checks tools that are specified as "toolAttributes": If they implement the ViewTool interface, they will get initialized with the Velocity context. This allows tools from the view package of Velocity Tools, such as LinkTool, to be defined as "toolAttributes" on a VelocityToolboxView, instead of in a separate toolbox XML file.

This is a separate class mainly to avoid a required dependency on the view package of Velocity Tools in VelocityView itself. As of Spring 3.0, this class requires Velocity Tools 1.3 or higher.

Since:

1.1.3

Deprecated.

Constructor Detail

VelocityToolboxView

public VelocityToolboxView()

Deprecated.

Method Detail

setToolboxConfigLocation

public void setToolboxConfigLocation(java.lang.String toolboxConfigLocation)

Deprecated.

Set a Velocity Toolbox config location, for example "/WEB-INF/toolbox.xml", to automatically load a Velocity Tools toolbox definition file and expose all defined tools in the specified scopes. If no config location is specified, no toolbox will be loaded and exposed.

The specified location string needs to refer to a ServletContext resource, as expected by ServletToolboxManager which is part of the view package of Velocity Tools.

org.apache.velocity.tools.view.servlet.ServletToolboxManager#getInstance

getToolboxConfigLocation

protected java.lang.String getToolboxConfigLocation()

Deprecated.

Return the Velocity Toolbox config location, if any.

createVelocityContext

protected Context createVelocityContext(java.util.Map<java.lang.String,java.lang.Object> model,
                                        HttpServletRequest request,
                                        HttpServletResponse response)
                                 throws java.lang.Exception

Deprecated.

Overridden to create a ChainedContext, which is part of the view package of Velocity Tools, as special context. ChainedContext is needed for initialization of ViewTool instances.

Overrides:

createVelocityContext in class VelocityView

Parameters:

model - the model Map, containing the model attributes to be exposed to the view

request - current HTTP request

response - current HTTP response

Returns:

the Velocity Context

Throws:

java.lang.Exception - if there's a fatal error while creating the context

See Also:

initTool(java.lang.Object, Context)

initTool

protected void initTool(java.lang.Object tool,
                        Context velocityContext)
                 throws java.lang.Exception

Deprecated.

Overridden to check for the ViewContext interface which is part of the view package of Velocity Tools. This requires a special Velocity context, like ChainedContext as set up by createVelocityContext(java.util.Map<java.lang.String, java.lang.Object>, HttpServletRequest, HttpServletResponse) in this class.

Overrides:

initTool in class VelocityView

Parameters:

tool - the tool instance to initialize

velocityContext - the Velocity context

Throws:

java.lang.Exception - if initializion of the tool failed
