Subject Re: [Axis2] axis2c - generated skeleton files using WSDL2C for array of structure having a RESET function. how to use it?
Date Wed, 28 Mar 2007 10:39:55 GMT

Thanks Milind,

NOw I have compiled all the the services, put the dll & lib's in  service
folder in AXIS2C
and trying to test it using the java client giving the error as  'Failed in
creating DLL  '
"in detail the error message is in below "  help me to solve the poblem.

1. I am just  calling a web service with single input in 
2.  it talks with some com dll and 
3. returns the result and then setting this response in webservices return.

"     
xP)rsion="1.0" encoding="UTF-8"?>
<soapenv:Envelope
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"><soapenv:Header></soapenv:Header><soapenv:Body><soapenv:Fault><faultcode>env:Receiver</faultcode><faultstring>Failed
in creating
DLL</faultstring></soapenv:Fault></soapenv:Body></soapenv:Envelope>
"

the response is not properly tagged .
