Hello Tomcat-experts!
I have recently bought some space at a webhotel that uses Apache HTTP server as
front before a Tomcat 6.0.37.My account at the webhotel is said to support
Struts and Hibernate and such technics.At home I have developed a app that uses
those technics and of course it runs fine in a similar environment as the one
at the webhotel. I can deploy my app as a ROOT-app or a ordinary app and the
Struts works perfectly.
At the webhotel I have tried to deploy it booth as a ROOT-app and as a
MYAPP-webapp-1.0.0.war-file
Now I have stripped the app down to just a struts2-hello-world-app.
But at the webhotel I just keep getting this when I try to access the
ActionClass through struts.xml:
HTTP Status 404 - There is no Action mapped for namespace [/] and action name
[welcome] associated with context path [/MYAPP-webapp-1.0.0].type Status
reportmessage There is no Action mapped for namespace [/] and action name
[welcome] associated with context path [/MYAPP-webapp-1.0.0].description The
requested resource is not available.
Unfortenatly the support guys at the webhotel says they lack knowledge of
Tomcat so they can not help me out.But today I at least found this exception in
the catalina.log just after my attempt yo access a struts-path:
/-- Encapsulated exception ------------\ java.lang.NullPointerException:

\--------------------------------------/
I'm pretty sure this exception come from me. So perhaps the webhotel-admin guys
has set upp my rights incorrect?
For a couple of weeks I have struggle to test different apache-mapping,
context.xml and struts-namespace-settings. At home it work but not at the
webhotel. Even though I start to think that it might not has anything to do
with this I just add some info below about my settings:
Apache-mappings (that I have set at the webhotel):/*.jsp /*.jspx /*.jsf
/servlet/* /*.do /MYAPP-webapp-1.0.0/* /*
(At home I just got: JkMount /* worker1)
Context.xml (from inside the MYAPP-webapp-1.0.0.war)<Context path=""
override="true" />
In my struts.xml I got this snippet: <package name="basicstruts2"
namespace="" extends="struts-default"> <action
name="login"> <result type="dispatcher">/login.jsp</result>
</action>
<action name="welcome"
class="se.MYAPP.web.actions.WelcomeUserAction"> <result
name="SUCCESS" type="dispatcher">/welcome.jsp</result> </action>
</package>
In my web.xml I got this snippet: <filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter-mapping> <filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern> </filter-mapping> But if I try to
access the struts paths
like:http://www.MYAPP.se/MYAPP-webapp-1.0.0/loginhttp://www.MYAPP.se/MYAPP-webapp-1.0.0/login.dohttp://www.MYAPP.se/MYAPP-webapp-1.0.0/login.action
...I just get the above 404.http://www.MYAPP.se/MYAPP-webapp-1.0.0/login.jsp of
course work.
So if you guys got any ideas or anything I could ask the webhotel-support-guys
to look for please let me know.Any ideas are most welcomeBest regardsFredrik
