Réf. : Axis/Tomcat Servlet Problem.

[va...@bull.net]

I had this problem and I solved it looking at the axis jar files : they
must be in a unique directory.
In your case, be sure they are in jakarta-tomcat-4.1.29/common/lib and
nowhere else under jakarta-tomcat-4.1.29/......

Objet :     Axis/Tomcat Servlet Problem.


Hi!

I have a problem running Axis 1.1 on Tomcat 4.1.29. The axis webapp
directory is deployed correctly and the validation of the installation
says,
everything should be working, but when I try to access the list of deployed
services (http://localhost:8042/XML2/servlet/AxisServlet) I get a 404 from
the Iexplorer (not a 404 from Tomcat, which says there's no such service).

Simultanously, I get a Java error on my console:

- Unable to locate a valid EngineConfigurationFactory
- Exception: java.lang.NullPointerException

In my server.xml, I defined an extra ContextPath via

 <Context path="/XML2" docBase="./ROOT/axis" debug="1"
reloadable="true"></Context>

All my Axis libraries are located in jakarta-tomcat-4.1.29/common/lib
(jaxrpc.jar and saaj.jar in common/endorsed). I already tried it with the
dirs in the axis/WEB-INF/lib directory, but with no effect.

Maybe, this has something to do with Tomcat, so here is an extract of the
Tomcat server.xml:

 <Service name="Tomcat-Standalone">
 <Connector className="org.apache.coyote.tomcat4.CoyoteConnector"
               port="8042" minProcessors="5" maxProcessors="75"
               enableLookups="true" redirectPort="8443"
               acceptCount="100" debug="1" connectionTimeout="20000"
               useURIValidationHack="false" disableUploadTimeout="true" />

 <Engine name="Standalone" defaultHost="localhost" debug="1">
  <Valve
className="org.apache.catalina.valves.RequestDumperValve"/>

       <Logger className="org.apache.catalina.logger.FileLogger"
               prefix="catalina_log." suffix=".txt"
               timestamp="true"/>

            <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
                  debug="0" resourceName="UserDatabase"/>
  <Host name="localhost" debug="1" appBase="webroot"
         unpackWARs="true" autoDeploy="true">

   <Valve
className="org.apache.catalina.valves.AccessLogValve"
                   directory="logs"
prefix="localhost_access_log." suffix=".txt"
                   pattern="common" resolveHosts="false"/>
                  <Logger className="org.apache.catalina.logger.FileLogger"
                   directory="logs"  prefix="localhost_log."
suffix=".txt"
              timestamp="true"/>

   <Context path="/XML" docBase="./ROOT/soap" debug="1"
reloadable="true">
   </Context>
   <Context path="/XML2" docBase="./ROOT/axis"
debug="1" reloadable="true">
   </Context>
  </Host>
 </Engine>
 </Service>

The axis/WEB-INF/web.xml file is like the standard file from the axis
package, didn't change anything.
Maybe, someone can help me or point me into the right direction.

Thanks in advance.
