Subject Invalid WSDD element 'service' (wanted 'deployment')
Date Wed, 02 Apr 2003 17:45:28 GMT
Hello Axis Users!

I have run into a bit of a wall here and desperately need to some advice
on how to fix it. I have been looking through the archives quite a bit
and haven't found anything "quite" like this problem. I have done the
basic axis install to the tomcat webapp directories, I am using the
latest version of xerces (2.4) with tomcat 4.1.3. My "happy" page comes
up just fine:

################END HAPPY.JSP

And I have uncommented the administration servlet lines from web.xml
because I want to be able to deploy using wsdd.

So this all sounds like goodness right? 

The problem is when I attempt to click on the Administer Axis link on
the main axis page (axis webapp) the following exeption is printed. This
seems like the most basic functionality, the link is on the main page
for goodness sake!

org.apache.axis.deployment.wsdd.WSDDException: Invalid WSDD element
'service' (wanted 'deployment')

I have attempted to use the basic deployment.wsdd that is in the user
guide and I get the exact same error. 

################BEGIN DEPLOYMENT.WSDD

<deployment
    name="FirstService"
    xmlns="http://xml.apache.org/axis/wsdd/" 
    xmlns:java="http://xml.apache.org/axis/wsdd/providers/java" 
    xmlns:xsd="http://www.w3.org/2000/10/XMLSchema" 
    xmlns:xsi="http://www.w3.org/2000/10/XMLSchema-instance"> 
    
    <service name="MyService" provider="java:RPC">
        <namespace>http://meis/mailservlet/</namespace> 
        <parameter name="className"
value="com.noi.web.services.MyService"/>
        <parameter name="allowedMethods" value="*"/>
    </service>

</deployment>

################END DEPLOYMENT.WSDD

So when this didn't work I went to a programattic approach thinking, hey
I have heard rumblings about people who don't like the administrator, so
why not use the servlet init approach:

EXACT SAME ERROR. I have tried so many things now I am at wit's end on
getting a wsdd to work. It seems that it barfing on the first tag, and
never even seing the deployment tag, so it gets lost. I guess I will
just have to use .jws files (that works) until this gets resovlved but
it seems to me to be a bad solution.
