Re: Recursive resources...

[Gabriel Egolf]

My apologies.  I was trying to make the example generic.  The resource 
call should indeed be <map:call resource="foo">.

According to the javadocs, the ResourceExistsAction takes a parameter 
named "src".  It could alternatively take a parameter named "url".  
Correct me if I'm wrong.

Hi all,

I have what I hope is a simple question.  Is it possible to create a 
resource that calls itself?  Here's an example of what I'm thinking.

<map:resource name="foo">
 <map:act type="resource-exists">
   <map:parameter name="src" value="{../path}/foo.xml"/>
   <map:generate src="{../path}/foo.xml"/>
   <map:serialize type="xml"/>
 </map:act>
 <map:call resource="foo">
   <map:parameter name="path" value="{path}/../"/>
 </map:call>
</map:resource>
..
<map:match pattern="**/foo.xml">
 <map:call resource="navigation">
   <map:parameter name="path" value="{1}"/>
 </map:call>
</map:match>
What I'm hoping to accomplish is to look for a file "foo.xml" in a 
given directory passed as the parameter "path".  If the file exists, 
generate it.  If the file doesn't exist, look in the parent directory 
for it.

So far, I haven't had any luck with this.  Instead of calling the 
resource again, I'm getting a 404 - Resource Not Found page.  Yes, 
the file does exist in the parent directory.  :)


For starters — your resource is named "foo", but you're calling a 
resource named "navigation"...?  And this doesn't look right:

   <map:parameter name="src" value="{../path}/foo.xml"/>


Where in that pipeline is anything that would use a parameter named 
"src"?
