Hi, i'm new to cayenne and i have a problem deploying a multi domain
app. I have followed cayenne's tutorial on how to deal with multi
domain applications, basically what i did was:
1. Put domains, nodes and cayenne xml files inside WEB-INF/lib;
2. Put the cayenne configuration path in web.xml;
3. Put the CayenneFilter in web.xml
4. I have a domain service class where i'm managing the domains:
public class DomainManagerImpl implements DomainManagerDAO {
public DataContext context = null;
public DataContext getContext(String domain) {
if (context == null || context.getParentDataDomain().getName() !=
domain) {
try {
context = DataContext.createDataContext(domain);
} catch (Exception e) {
e.printStackTrace();
}
}
return context;
}
}
my web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd";>
<web-app>
<display-name>mywebapp</display-name>
<context-param>
<!-- informs Tapestry where to look for pages, components and
mixins. -->

<param-value>com.example.mywebapp</param-value>
</context-param>
<context-param>
<param-name>cayenne.configuration.path</param-name>
<param-value>/WEB-INF/config/cayenne-files</param-value>
</context-param>
<filter>
<filter-name>app</filter-name>
<filter-class>org.apache.tapestry5.TapestryFilter</filter-
class>
</filter>
<!-- Filter for cayenne context -->
<filter>
<filter-name>CayenneFilter</filter-name>
<filter-
class>org.apache.cayenne.conf.WebApplicationContextFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>CayenneFilter</filter-name>

</filter-mapping>
<filter-mapping>
<filter-name>app</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>
and when deployed i'm getting the following error:

I have searched in the web for errors like this but found nothing,
what's the best approach when dealing with multi domains
configuratiion files?
I'm using Cayenne 3.0M6 server, Tapestry 5.1, Glassfish v2 on Mac OS
X. TIA.
Oh, forgot to say that i have reengineered a postgres db using
modeller and it generated all the classes, i did nothing, just watch!
Wonderful!
