Deploying a simple handler
Hi,
I'm trying to put a simple handler on the request flow of a service. My
handler extends org.apache.axis.handlers.BasicHandler (implementing
invoke() and nothing else). The AdminClient deploys the service OK, but
when viewing the list of deployed services, I get a ClassCastException:
Exception - org.apache.axis.ConfigurationException:
java.lang.ClassCastException java.lang.ClassCastException
at
org.apache.axis.deployment.wsdd.WSDDDeployableItem.makeNewInstance(WSDDDeployableItem.java:338)
(full stacktrace at the end of this message).
The relevant part of the wsdd file:
<service ... > ...
<requestFlow>
<handler type="java:myPkg.MyHandler"/>
</requestFlow> ...
</service>
This is all using tomcat 5.5.4-compat and axis 1.1.
Others have had this problem trying to deploy JAX-RPC handlers as
org.apache.axis.handlers.Handlers, and vice versa, but I'm not doing that -
can anyone see where I'm going wrong?
Any help appreciated!
James

Strange ClassCastException from a handler
Posted by James Brady <jc...@cam.ac.uk>.
I'm having trouble deploying a custom handler into the requestFlow of a
service - I've tried everything I can think of, but got nowhere :(
The WSDD file is processed without error. The problem appears when viewing
the AxisServlet: Exception - org.apache.axis.ConfigurationException:
java.lang.ClassCastException java.lang.ClassCastException
at
org.apache.axis.deployment.wsdd.WSDDDeployableItem.makeNewInstance(WSDDDeployableItem.java:338)
My handler class:
package gs.psource.handlers;
// imports
public class CDDBHandler extends BasicHandler {
public void invoke(MessageContext mc) throws AxisFault {
}
}
Yes, it is empty - it is in a jar file placed in tomcat's shared/lib
directory. The handler is included in my WSDD file:
<requestFlow>
<handler name="CDDBHandler"
type="java:gs.psource.handlers.CDDBHandler"/>
</requestFlow>
I know the handler is to blame, because when I comment out this part of the
WSDD file, AxisServlet works correctly. However, I have also been able to
deploy other, identical, custom handlers from different packages.
Using:
tomcat-5.54-compat
axis-1.1
j2sdk-1.4.2
(Full WSDD file and stacktrace below)
This has beaten me - has anyone got any ideas?
