Error while generating client side code using axis soap engine.

Ashutosh Kumar Mon, 30 Jan 2006 04:44:27 -0800

Hi,

I am using the new wsdl file attached here with this mail for getting the stock quotes from http://ws.invesbot.com/ using the "getquote" API exposed by www.xmethods.net. When I am trying to generate the client side code using Axis SOAP Engine, I am getting following errors

**********************************************************

Code generation failed. Please see errors below.

java.lang.NullPointerException

at org.apache.axis.wsdl.wsdl2ws.WSDL2Ws.addDocumentStyleOutputMessageToMethodInfo(WSDL2Ws.java:340 )

at org.apache.axis.wsdl.wsdl2ws.WSDL2Ws.setMethodInfo(WSDL2Ws.java:247)

at org.apache.axis.wsdl.wsdl2ws.WSDL2Ws.getServiceInfo(WSDL2Ws.java:214)

at org.apache.axis.wsdl.wsdl2ws.WSDL2Ws.generateWrappers(WSDL2Ws.java:653)

at org.apache.axis.wsdl.wsdl2ws.WSDL2Ws.main(WSDL2Ws.java:1134)

***********************************************************
Earlier, the stock quote wsdl that was provided is also attached here with this mail and the client code generated using the older wsdl was working fine. This new wsdl file is giving the above mentioned errors.Please help.

Thanks & Regards
Ashutosh Kumar
