Hi,
i need my application to send emails with the link to the specific
tapestry
page. How would i generate a link?
I tried extending a page with IExternalPage and using the address:
http://localhost:8080/BioJazz/app?service=external/HitList
What i get is RuntimeException: No engine service named
'external/HitList'
is available.
Link (as in ExternalService API doc):
http://localhost:8080/BioJazz/app?service=external&context=HitList
gives a
null pointer exception:
- org.apache.hivemind.util.Defense.notNull(Defense.java:41)
-
org.apache.tapestry.engine.RequestCycle.getPage(RequestCycle.java:242)
- org.apache.tapestry.engine.ExternalService.service(
ExternalService.java:144)
- $IEngineService_10c8121ee8c.service($IEngineService_10c8121ee8c.java)
Any hint?
Thanks,

Do not form links manually, use "tapestry.services.External" service (
in your case ).
First inject it into your page with something like:
<inject property="externalService"
object="service:tapestry.services.External" /> in your page file.
Be sure that you have a externalService property getter like:
public abstract IEngineService getExternalService();
Then, when you need to generate link, just use
"org.apache.tapestry.engine.ExternalServiceParameter"
to generate your page parameters ( name and Object[] ) and call
getExternalService().getLink( your parameter object ).
This will return ILink object and you will be able to call
getAbsoluteURL on it, which will return required Link as a string.
On the page you can probably put it using @Any component, like:
<a jwcid="@Any" href="yourLink">go go go</a>
