Java WSImport tool fails to generate JAX-WS SOAP client from WSDL

Question

I have a web service and I'm always using Java's wsimport tool to generate a JAX-WS SOAP client from the service's WSDL.

I've started getting an error lately while generating the client, here is the stack trace:

IOException thrown when processing "http://localhost:60952/?xsd=xsd0". Exception: java.net.SocketException: Connection reset.
 Exception in thread "main" com.sun.tools.internal.ws.wscompile.AbortException

I checked and it looks like it is happening because of some limit in the number of APIs in the WSDL. (43 for exactly)

When I remove one API, no matter which one, the generation is passing successfully.

When I'm adding again an API and it reaches the limit, the generation fails.

I've tried using WSImport from JDK 7 & 8.

Here is the definitions of the WSDL:

wsdl:definitions xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:soap12="http://schemas.xmlsoap.org/wsdl/soap12/" xmlns:tns="http://tempuri.org/" xmlns:wsa="http://schemas.xmlsoap.org/ws/2004/08/addressing" xmlns:wsx="http://schemas.xmlsoap.org/ws/2004/09/mex" xmlns:wsap="http://schemas.xmlsoap.org/ws/2004/08/addressing/policy" xmlns:wsaw="http://www.w3.org/2006/05/addressing/wsdl" xmlns:msc="http://schemas.microsoft.com/ws/2005/12/wsdl/contract" xmlns:wsp="http://www.w3.org/ns/ws-policy" xmlns:wsa10="http://www.w3.org/2005/08/addressing" xmlns:wsam="http://www.w3.org/2007/05/addressing/metadata" name="MyService" targetNamespace="http://tempuri.org/">

</xsd:schema>
</wsdl:types>

Parameters for WSImport: -s C:\\output -p my.package http://localhost:60952/?wsdl

Is anyone familiar with this issue?

How can I debug the WSImport tool through Java? Couldn't find the sources.

Answer 1

You can debug it using the -verbose switch:

Solaris/Linux
/bin/wsimport.sh -verbose

Windows
\\bin\\wsimport.bat -verbose

The error also seems to be that your server (your own computer) whether it be websphere, JBoss or GlassFish is resetting the connection. Can you try restarting it to see if the error goes away? Also, possibly try increasing the amount of memory allocated to it?
