Thanks, Ruchith:
The null pointer was caused by server side not configured properly. But now I
am facing another problem. I am using a standalone java application to access
the web service. I use the code copied from the TestWSSecurityNew6 class to
encrypt and sign the soap envelope. I configured the deploy.wsdd on server side
as the following:
<requestFlow>
<handler name="DoSecurityReceiver"
type="java:org.apache.ws.axis.security.WSDoAllReceiver">
<parameter name="user" value="wss4jcert"/>
<parameter name="mustUnderstand" value="false"/>
<parameter name="timestampStrict" value="false"/>
<parameter name="passwordCallbackClass"
value="com.nortel.ca.wcars2g7.axis.services.NEService.PWCallback"/>
<parameter name="action" value="Encrypt Signature"/>
<parameter name="enableSignatureConfirmation" value="false" />
<parameter name="decryptionPropFile" value="cryptoSKI.properties" />
<parameter name="signaturePropFile" value="cryptoSKI.properties" />
<parameter name="decryptionKeyIdentifier" value="X509KeyIdentifier" />
</handler>
</requestFlow>
And my client can access the web service and get the result back correctly.
Once I try to configure the "responseFlow" on server side to encrypt and sign
the soap envelope, it begins to throw various exceptions. My question is how
can I hook the security header processing handler to my standalone client
application and what is the correct responseFlow configuration on the server
side that will encrypt and sign the evelope as exactly the same as my client
does?
Thanks for your time.

Hi,
hmm ... this seems to be an Axis 1.x issue ... unfortunately I'm not an expert
on it :-(
Thanks,
Ruchith
