Description

« Hide

When freemarker is used with web frameworks (e.g. WebWork, Struts2) there are several variables that are always available.
Currently these are highlighed as "cannot resolve variable..." but it would be good if when using a Struts2 facet these were recognised.

For example for Struts2 (http://struts.apache.org/2.x/docs/freemarker.html)

Name	Description
stack	The value stack itself, useful for calls like ${stack.findString('ognl expr')}
action	The action most recently executed
response	The HttpServletResponse
res	Same as response
request	The HttpServletRequest
req	Same as request
session	The HttpSession
application	The ServletContext
base	The request's context path

there should probably be something like FreemarkerDefaultVariableProvider-EP which can be implemented to provide those predefined names

As for Struts2, yes. But in general I believe that some user-editable table in UI will be sufficient.

For Spring MVC, there's "springMacroRequestContext" with type "org.springframework.web.servlet.support.RequestContext" (applies to both Freemarker as well as Velocity).

Spring MVC puts some more variables in model in org.springframework.web.servlet.view.freemarker.FreeMarkerView#doRender method.
These are:

JspTaglibs        - freemarker.ext.jsp.TaglibFactory
Application       - freemarker.ext.servlet.ServletContextHashModel
Session           - freemarker.ext.servlet.HttpSessionHashModel
Request           - freemarker.ext.servlet.HttpRequestHashModel
RequestParameters - freemarker.ext.servlet.HttpRequestParametersHashModel
