Problems adding Axis2 to an existing Webapp
Hi,
I have an existing webapp. Now, I want to add Axis2 to expose some classes
as web service. I can't alter the structure of the existing webapp. I added
the Axis2 libs to WEB-INF/ and I will later strip out the libs not actually
needed. At the moment the content of WEB-INF/lib is:

I created a small example, just consisting of a servlet and a POJO java
class, which should be exposed as web service. The webapp folder structure
looks as follows:
|-- META-INF
|-- WEB-INF
| |-- classes
| | `-- de
| | `-- hpfsc
| | |-- Echo.class
| | `-- EchoServlet.class
| |-- lib
| | |-- ...
| |-- services
| | `-- Echo
| | |-- META-INF
| | | `-- services.xml
| `-- web.xml
`-- index.jsp
I added Axis to my web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version="2.4"
xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee

<welcome-file>default.html</welcome-file>
<welcome-file>default.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>
</web-app>
Finally, I created a services.xml file to expose de.echo.Echo class as a web
service. The content of the file looks as follows:
<?xml version="1.0" encoding="UTF-8"?>
<service name="Echo" scope="application">
<description>EchoAxis2</description>
<messageReceivers>
<messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-only"
class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver"/>
<messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-out"
class="org.apache.axis2.rpc.receivers.RPCMessageReceiver"/>
</messageReceivers>
<parameter name="ServiceClass">de.echo.Echo</parameter>
</service>
My first question is if there is a XML Schema file (XSD) available to
validate the services.xml file?
Now, if I deploy this complete web app on Tomcat, I get the following
exception:
12.08.2007 14:52:25 org.apache.axis2.deployment.ServiceDeployer deploy
SCHWERWIEGEND: The Echo service, which is not valid, caused Processing

I think the second part is more interesting, because it says that my class
de.echo.Echo can't be found. Any ideas what I'm doing wrong? Do I have to
specify somehow a path where Axis should look for class files? I'm pretty
sure it must work somehow like that, because I was able to generate such an
example webapp using Eclipse and Axis1.

Sebastian

Argg, what a stupid mistake. Thanks for spotting!

Sebastian,
Your ClassNotFoundException is due to the package of your deployed Echo class not matching the ServiceClass package value in your services.xml.
-- WEB-INF
> | |-- classes
> | | `-- de
> | | `-- hpfsc
> | | |-- Echo.class
vs
<parameter name="ServiceClass">de.echo.Echo</parameter>
So, the ServiceClass value should be:
<parameter name="ServiceClass">de.hpfsc.Echo</parameter>
There is no need to explicitly identify a class location, it just needs to be in the classpath of the web app (classes, web-inf/lib) or in the service aar file directly.
Thanks,
Ted
