Hi,

I am stuck with a problem. I have a SOAP web service(secured with password) which I am trying to access using ws:outbound-gateway. Here is my config file looks like below.

<?xml version="1.0" encoding="UTF-8"?>

But, I got an error while sending the request.

I have also used interceptor like this, but this also didn't work.
<bean id="wss4jSecurityInterceptor"
class="org.springframework.ws.soap.security.wss4j. Wss4jSecurityInterceptor">
<property name="securementActions" value="UsernameToken" />
<property name="securementUsername" value="OmigService" />
<property name="securementPassword" value="Omig#3021!" />
<property name="securementPasswordType" value="PasswordText" />
</bean>
Also, to mention, I get correct response back from Web Service when I use SOAPUI or any other Web Service client.

Can some one let me know the cause of the exception and how to resolve it?

Thanks,
Avinash
