As you can see from the response, an exception is being thrown.
Unfortunately, Tomcat does not do a getRootCause on the ServletException and
provide a stack trace of the root cause, which is what would be most useful.
>From the line numbers, it looks like you are using SOAP 2.3 or later. Is
that correct? If you are using the 2.3 or 2.3.1 release builds, something
that has caused this exception for others is in the handling of the fault
router in the deployment descriptor. Specifically, leading white space in
the text leads to an NPE.
This is OK:
<isd:faultListener>org.apache.soap.server.DOMFaultListener</isd:faultListene
r>
This causes an NPE:
<isd:faultListener>
org.apache.soap.server.DOMFaultListener</isd:faultListener>
Unfortunately, without information from the root cause, this is hard to
analyze. Can you try other versions of Tomcat and/or SOAP? If there is a
later version of Tomcat than you are using, perhaps it prints root cause
information. The nightly build of SOAP *may* behave slightly differently,
but not much has changed in this piece of code.
Also, you may want to check Tomcat's logs to see if it logged root cause
information, or check the Tomcat docs for whether there is some config
option to show root cause.
