Hi,
I tried to get the dwr running. I uncommented the part in the dwr.xml. It
looks like that:
<!DOCTYPE dwr PUBLIC
"-//GetAhead Limited//DTD Direct Web Remoting 2.0//EN"
"http://getahead.ltd.uk/dwr/dwr20.dtd";>
<dwr>
<allow>
<create creator="spring" javascript="UserManager">
<include method="getUsers"/>
</create>
<convert converter="bean" match="org.appfuse.model.User"/>
</allow>
</dwr>
Now I tried to find the webpage that describes the functions provided. It
should be http://localhost:8080/[YOUR-WEBAPP]/dwr/
What exactly is my webapp? Is this the name of my project I specified when
creating the appfuse project? Cause that does not work. Is there any check
if dwr is running? Or do I have to do anything to get it running? I searched
the entire directory for an engine.js, so I assume that it does not run yet.
Any suggestions?
Thanks in advance
