Subject Re: Adding Tomcat Valve specific web apps
Date Tue, 27 Feb 2007 18:50:26 GMT
Is the <valve-chain> element supposed to refer to a GBean valve name?  I've
tried this but I'm getting deployment errors.

I have defined the following valve chain in my config.xml

----
            <gbean name="FirstValve">
                  <attribute
name="className">org.apache.catalina.valves.AccessLogValve</attribute>
                  <attribute name="initParams">prefix=0.0.0.0_access_log.
                  suffix=.txt
                  pattern=common</attribute>
                  <reference name="NextValve">
                        <pattern>
                              <name>SecondValve</name>
                        </pattern>
                  </reference>
            </gbean>
            <gbean
name="org.apache.geronimo.configs/tomcat/1.2-SNAPSHOT/car?ServiceModule=org.apache.geronimo.configs/tomcat/1.2-SNAPSHOT/car,j2eeType=GBean,name=SecondValve"
 gbeanInfo="org.apache.geronimo.tomcat.ValveGBean">
                  <attribute
name="className">org.apache.catalina.authenticator.SingleSignOn</attribute>
            </gbean>
            <gbean
name="org.apache.geronimo.configs/tomcat/1.2-SNAPSHOT/car?ServiceModule=org.apache.geronimo.configs/tomcat/1.2-SNAPSHOT/car,j2eeType=GBean,name=BasicAuthValve"
 gbeanInfo="org.apache.geronimo.tomcat.ValveGBean">
                  <attribute
name="className">org.apache.catalina.authenticator.BasicAuthenticator</attribute>
                  <attribute
name="initParams">disableProxyCaching=false</attribute>
                  <reference name="NextValve">
                        <pattern>
                              <name>FirstValve</name>
                        </pattern>
                  </reference>
            </gbean>

The config.xml defines a default valve chain consisting of "FirstValve" and
"SecondValve".  Now, in certain specific web apps, I want to define the
<valve-chain> element in the geronimo.web.xml so that I can extend this
valve chain with another valve, but just for the specific web app.  In the
geronimo-web.xml, I will add the following element:

----
<valve-chain>BasicAuthValve</valve-chain>
----

I'm hoping that this "pre-appends" the BasicAuthValve valve to the valve
chain, since the BasicAuthValve has the "FirstValve" as a GBean reference.

As I stated before, I'm getting a deployment error when this occurs:

----
     [java]       The service
     [java]
J2EEApplication=Mxi/Maintenix/1/ear,j2eeType=WebModule,name=induction.war
     [java]     did not start because
     [java]
Mxi/Maintenix/1/ear?J2EEApplication=Mxi/Maintenix/1/ear,WebModule=induction.war,j2eeType=TomcatValve,name=BasicAuthValve
     [java]     did not start.
----

It seems that the deployer is trying look for the BasicAuthValve GBean in
the web app itself.  Anybody have any ideas on how I can get this working?

Thanks,
Aman
