Struts and displaytag

[Thomas Hamacher <th...@qualiads.de>]

Hi,

as we had a few display:*-tag questions in here in the last days I wonder if 
anyone found a solution to this problem:

I´m using the display:* together with Struts 1.2.7 and this works quite good 
so far. But I´m experiencing the following problem now:

I´m using a wrapper/decorator to create an image together with a link. But in 
my wrapper-method I can only create a link like this:

return "<a href=\"/context/html/myPage.do\" ...... />

Unfortunately the reference to "myPage" is not relative, so I have to use a 
path. As I don´t want to hardcode this path in my wrapper-class, but use it 
through my struts-config I´d like to use the relevant struts-tag. In this 
case this would be <html:rewrite action="/myPage" /> which returns me the 
correct path regarding the contextURL etc. Unfortunately this <html:rewrite> 
will not be executed if I simply return the struts-tags in my wrapper-class. 
Is there a solution to this problem?

Same thing to this display:*-tag
<display:column valign="top" property="name" ..... 
href="/context/html/myPage.do" />

The href="..." should be replaced by <html:rewrite>. But the struts-tags are 
not allowed within the <display:table>. Does this have anything todo with EL? 
Does anyone has an example for this?

Thank you very much for your help
Thomas

Thomas,

in my decorators I typically take the current context path from the
PageContext like this:

	PageContext pc = getPageContext();
	HttpServletRequest request = (HttpServletRequest)pc.getRequest();
	String contextPath = request.getContextPath();
