code runs fine in eclipse , after running url is : http://localhost/demo2/login.jsp, a simple login screen, enter the user name password can not log into the inside pages , url is http: / / localhost/demo2 / beginning .
problem after deployment , the deployment directory structure:
which , web.xml in WEB-INF directory , struts.xml in build / classes directory
url is accessible after running http://localhost/login.jsp, normal open , click submit when given:
HTTP Status 404 - There is no Action mapped for namespace [/] and action name [userLogin] associated with context path [].
after the release of the server.xml file (host node ) :
<Host name="localhost" appBase="E:/JavaProjects/demo2_publish"
unpackWARs="true" autoDeploy="true">
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
prefix="localhost_access_log." suffix=".txt"
pattern="%h %l %u %t "%r" %s %b" />
</Host>
run in eclipse , is in a Tomcat v7.0 Server at localhost running , I looked at it also has its own server.xml file :
<Host appBase="E:/JavaProjects" autoDeploy="true" name="localhost" unpackWARs="true">
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" pattern="%h %l %u %t "%r" %s %b" prefix="localhost_access_log." suffix=".txt"/>
<Context docBase="demo2" path="/demo2" reloadable="true" source="org.eclipse.jst.jee.server:demo2"/>
</Host>
After running I want to open the address without demo2 it has not been fix , solution ?
------ Solution ---------------------------------------- ----
submitted to the action when the namespace errors .
------ Solution ---------------------------------------- ----
namespace = " / "
------ Solution --------------------- -----------------------
you change the air or give him a name . Then form tag when adding namespace.
------ Solution ---------------------------------------- ----
------ Solution --------- -----------------------------------
Of course, you can refer to my example of this free program , which is also used struts, I believe that your help is still there

with this configuration ?
I replaced this configuration
open http://localhost/login.jsp time , tomcat had warned :
life and death that can not find this action userLogin
jsp file :
------ Solution -------------------- ------------------------
do not use a relative path because you start to go in and do not in this namespace , so coupled with engineering name , becomes absolutely Road King , you can access to !
------ For reference only -------------------------------------- -
namespace = "/" after such a change , or
HTTP Status 404 - There is no Action mapped for namespace [/] and action name [userLogin] associated with context path ; [ ] .
This error
------ For reference only -------------------------------- -------
namespace = "/ demo"
jsp file :
tomcat there is a warning :
how configuration changes the feeling did not work ? I had a tomcat restart
looked Html generated inside is this:
