I also get the same error when generating types from amazon web service at http://www.xmlme.com/WSAmazonBox.asmx?wsdl using jbossws-1.0.4

Same error on the WSDL below.
WSDL is generated by Axis 1.2.1 Given that soap encoding is not supported we tried with document/literal and wrapped but always with the same results...

The problem lies in a simple string[] description

Our WSDL:

It looks like this is the same error reported earlier (http://jira.jboss.org/jira/browse/JBWS-1260), but that was only occurring on wsdl-java when the unwrap=true attribute was used.
It appears from the new stack trace that wsdl-java is using unwrap even when it is NOT specified.

Using an AXIS2 WSDL I fall in a slight variation the error:

We are still stuck into this.
It's a new project so we tried to write the server with different vendors.

AFAIK for WS which returns arrays JBossWS seems to be able to generate a client only for WSDL generated from a JBossWS stack.

Comparing different WSDL, I saw that when array comes in, other vendors generates the WSDL in this way:

<s:complexType>

<complexType name="String.Array">

String passed is null

The reason this is suddenly apeared for JBossWS 1.0.4.GA is because we now unwrap the parameters by default.

While we are working on this you can workaround the problem by setting the parameter-style to 'bare' e.g.

<wsdl-java location="SomeWSDL.wsdl" parameter-style="bare">

hI.

I ran into the same problem. Try using

<wsdl-java location="..." parameter-style="bare">
