	A reference to the toolbox manager.

Constructor Detail

VelocityManager
protected VelocityManager()(Code)

Method Detail

createContext

public Context createContext(OgnlValueStack stack, HttpServletRequest req, HttpServletResponse res)(Code)

This method is responsible for creating the standard VelocityContext used by all WW2 velocity views. The following context parameters are defined:

req - the current HttpServletRequest
res - the current HttpServletResponse
stack - the current OgnlValueStack
ognl - an OgnlTool
webwork - an instance of com.opensymphony.webwork.util.WebWorkUtil
action - the current WebWork action

a new WebWorkVelocityContext

getInstance
public static synchronized VelocityManager getInstance()(Code)
	retrieve an instance to the current VelocityManager

getVelocityEngine
public VelocityEngine getVelocityEngine()(Code)
	a reference to the VelocityEngine used by all webwork velocity thingies with the exception ofdirectly accessed *.vm pages

getVelocityProperties
public Properties getVelocityProperties()(Code)
	the velocityProperties

init
public synchronized void init(ServletContext context)(Code)
	initializes the VelocityManager. this should be called during the initialization process, say by ServletDispatcher. this may be called multiple times safely although calls beyond the first won't do anything Parameters: context - the current servlet context

init
protected void init()(Code)
	performs one-time initializations

initChainedContexts
protected void initChainedContexts()(Code)
	allow users to specify via the webwork.properties file a set of additional VelocityContexts to chain to the the WebWorkVelocityContext. The intent is to allow these contexts to store helper objects that the ui developer may want access to. Examples of reasonable VelocityContexts would be an IoCVelocityContext, a SpringReferenceVelocityContext, and a ToolboxVelocityContext

initToolbox
protected void initToolbox(ServletContext context)(Code)
	Initializes the ServletToolboxManager for this servlet's toolbox (if any).

loadConfiguration
public Properties loadConfiguration(ServletContext context)(Code)
	load optional velocity properties using the following loading strategy relative to the servlet context path relative to the WEB-INF directory on the classpath Parameters: context - the current ServletContext. may not be null the optional properties if webwork.velocity.configfile was specified, an empty Properties file otherwise

newVelocityEngine

protected VelocityEngine newVelocityEngine(ServletContext context)(Code)

Instantiates a new VelocityEngine.

The following is the default Velocity configuration

 resource.loader = file, class
 file.resource.loader.path = real path of webapp
 class.resource.loader.description = Velocity Classpath Resource Loader
 class.resource.loader.class = com.opensymphony.webwork.views.velocity.WebWorkResourceLoader

this default configuration can be overridden by specifying a webwork.velocity.configfile property in the webwork.properties file. the specified config file will be searched for in the following order:

relative to the servlet context path
relative to the WEB-INF directory
on the classpath

Parameters:
context - the current ServletContext. may not be null

prepareChainedContexts
protected VelocityContext[] prepareChainedContexts(HttpServletRequest servletRequest, HttpServletResponse servletResponse, Map extraContext)(Code)
	constructs contexts for chaining on this request. This method does not perform any initialization of the contexts. All that must be done in the context itself. Parameters: servletRequest - Parameters: servletResponse - Parameters: extraContext - an VelocityContext[] of contexts to chain

setVelocityProperties
public void setVelocityProperties(Properties velocityProperties)(Code)
	Parameters: velocityProperties - the velocityProperties to set
