Re: Strus2, Freemarker and getting request.getContextPath()

[Adam Lister]

Sorry, should have read the original question more carefully!


Because he provided JSP syntax (more accurate the OGNL syntax inside an S2 
"property" tag in either JSP or FreeMarker). A plain %{expression} inside 
FreeMarker, IIRC, would be meaningless.

FreeMarker, IIRC, would be meaningless.

Another FreeMarker page at [1] provides different names for the scopes; I don't 
know why the two docs aren't the same, or which is correct. You should also be 
able to access the values via the OGNL syntax inside an <@s.property...> 
FreeMarker "tag".

Re: Strus2, Freemarker and getting request.getContextPath()

[doahh]

Thanks again for the reply, it didn't work for me but I managed to get it
thanks to the documentation you pointed me towards. I got it through:

${action.servletResponseFromActionContext.contextPath}

where 'servletResponseFromActionContext' is a method
'getServletResponseFromActionContext' of my action that returns the real
HttpServletRequest object. My method is:

public HttpServletResponse getServletResponseFromActionContext(){

ActionContext actionContext = ActionContext.getContext();
final HttpServletResponse response = (HttpServletResponse)
actionContext.get(StrutsStatics.HTTP_RESPONSE);
return response;
}

and your action must implement 'ServletResponseAware'.

I have no idea why the mehtod you gave doesn't work for me but I always got
the string printed out as plain text - odd as obviously I can use the
'action' parameter OK (I can also use the 'struts' parameter).

%{#request}

That should get you the request context, as stated in:
http://struts.apache.org/2.x/docs/ognl.html

Towards the top, under the "Objects in the Context" is.

Strus2, Freemarker and getting request.getContextPath()

[doahh]

I expect this is probably very easy but I have not seen and description
anywhere of how to do it. I currently have this in a Struts2 enabled jsp
page:

<%request.getContextPath()%>

and need to convert it to freemarker. I have tried the obvious:

${request.contextPath}
${request.getContextPath}

and also adding a servlet filter (and when that failed an interceptor) that
sets:

request.setAttribute("requestObject" , request);

but the best error I can get is:

freemarker.beans  - Key 'requestObject' was not found on instance of
org.apache.struts2.dispatcher.StrutsRequestWrapper

How can I get access to the Request object inside of my Freemarker template
when I am using Struts 2?
