New entities in struts-config?

["Wilson, Wayne" <ww...@ettain.com>]

Hi, 

In order to be able to toggle back and forth between secure and insecure
mode (https & http) I have had to use some static URLs in the
global-forwards section of the struts-config. Since this app gets deployed
into multiple environments (with different hostnames) I would like an easier
way to update my struts-config with the hostnames. I created a custom dtd
(and pointed the struts-config at it) with a new HOST entity (and a
reference to the existing dtd for all the rest): 

<?xml version="1.0" encoding="ISO-8859-1"?> 

<!ENTITY HOST "localhost">
<!ENTITY % struts-config SYSTEM
"http://jakarta.apache.org/struts/dtds/struts-config_1_0.dtd"> 

 

which I used in my path attribute in a forward tag in the struts-config: 

<global-forwards>
<forward name="test1" redirect="true" path="http://&HOST;/test.jsp"/>
<forward name="test2" redirect="true" path="https://&HOST;/test.jsp"/>
</global-forwards> 

 

This worked fine when opened up the struts-config.xml in IE, but Tomcat
(Struts) complained that HOST wasn't defined. Is the digester going straight
to the "official" dtd and ignoring mine? Does anyone know what I am doing
wrong or how else I can do this type of replacement in the struts-config? 

Thanks, 

Wayne Wilson

Deft handling of HTTPS is a blind spot in the framework. I do think we
need a better all-around solution for this. For now, you could set up
alternate struts-config's for each host, and then edit the web.xml when
its deployed. But that's really messy. The entity in the DTD is a clever
idea but that also requires editing the configuration after it is
deployed.

Another alternative would be to use a utility method in the Action which
turned the context relative path into an absolute path using a specified
scheme and port. Something that looked like this: 

ActionForward newForwardAbsolute( HttpServletRequest request,
ActionForward forward, String scheme, String port); 

So this would return a new ActionForward based on the first, but with an
adjusted path. 

In the Action, you could call it like this:

return newForwardAbsolute(request, mapping.findForward("continue"),
"HTTPS", ""); 

If you do anything like this, please consider contributing it back to
the community as an enhancement request to RequestUtils.
