relative urls

[Nathan Coast <na...@cableinet.co.uk>]

Hi,

I've got an app that will be deployed to a number of different contexts

/test
/dev
/staging
/ 
	(root)

The app contains a large amount of static content e.g. images which will always 
be referenced from "/current_context/image"

some of the jsps are accessed directly and via the action servlet - sometimes 
with different depths for the action url e.g.
/current_context/something/something_else/my_action.do
/current_context/something/another_action.do
/somepage.jsp

this obviously rules out using relative urls for the static content but the 
changing contexts makes it difficult for basing the urls on root.

Is the solution to precede the url to every image in every jsp with a variable 
containing the value of the context?  Is this not a performance hit?  What's the 
best way to do it? Is there a struts tag that does this for me? How do I achieve 
world peace? - oops wrong mail list.

Thanks
Nathan

cheers

this is what I figured, seems like an unpleasant overhead object - instantiation 
and 3 method calls for every relative url in the site every time every page is 
accessed.

Must be some hack to get the context and place it into a static final variable 
somewhere prior to jsp compilation.  This would effectively compile the variable 
value into every jsp.  Any ideas?

I ran into this same issue.  I accomplished this by
creating a custom tag (in my case called, PageLoader).
 The PageLoader tag will expose a scripting variable
called contextRoot, which is basically
pageContext.getRequest()).getContextPath()
