External Link Question

I need to create a link to be placed in an email that
will take the recipient into a 'ProTrack' Tapestry app
to the page that displays info about a particular item
(or set of items) stored in a DB - similar to the VLib
ViewBook page. However, my attempts so far have
failed. Briefly, i have Item.html - Item.java
implements IExternalPage and the activateExternalPage
method strips out the parameter and uses it to
retrieve the Item from the DB and display it. I am
trying to call this page with the URL below. However,
I just get automatically sent to the home page. Any
pointers?

http://localhost:8080/ProTrack?service=external&context=Item&sp=178

It should be 
http://localhost:8080/ProTrack?service=external/Item&sp=178

The context is just the page name.

It was the URL that caused the problem, but i needed
to specify:

http://localhost:8080/ProTrack/app?service=external/Info&sp=S178

i.e leave out the context parameter and specify the
app servlet to get it to work. Leaving out app always
sends me to the Home page. Specifying the
&context=Info always threw an error
org.apache.tapestry.ApplicationRuntimeException 
Service external requires exactly one context
parameter. 

For reference my web.xml contains:

    <filter>
        <filter-name>redirect</filter-name>
       
<filter-class>org.apache.tapestry.RedirectFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>redirect</filter-name>
        <url-pattern>/</url-pattern>
    </filter-mapping>
    <servlet>
        <servlet-name>ProTrack</servlet-name>
       
<servlet-class>org.apache.tapestry.ApplicationServlet</servlet-class>
        <init-param>
        
<param-name>org.apache.tapestry.visit-class</param-name>
        
<param-value>nz.cri.gns.protrack.Visit</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>ProTrack</servlet-name>
        <url-pattern>/app</url-pattern>
    </servlet-mapping>
 

Cheers

paul

I think you URL is wrong, it should look like:
http://localhost:8080/ProTrack?service=external/<pagename>&context=Item&sp=178
as otherwise the external service does not know which page should be displayed

Cheers,
 Markus
