WSDLException : An error occurred trying to resolve schema referenced at

问题

I'm trying to generate a proxy class from a local WSDL file with eclipse Galileo and axis 2 1.4 on windows xp . My problem is that i get an error due to an imported schema inside the WSDL . The line tha troubles me is :

<xsd:import namespace="http://www.w3.org/2005/05/xmlmime" schemaLocation="http://www.w3.org/2005/05/xmlmime"/>

I've tried to run the wsdl2java following command:

wsdl2java.bat  -uri SOAService.wsdl -o D:\temp p test -d xmlbeans -a -s -ns2p -uw

and I get the following exception:

Exception in thread "main" org.apache.axis2.wsdl.codegen.CodeGenerationException

I suspect it's due to the system proxy which doesn't let retrieve the xsd to the wsdl2java tool. In fact i can download the file from the browser without problems.

There's an option to specify a proxy to wsdl2java or someone has resolved this issue ? For the moment i've downloaded the XSD, added it to the project and changed the WSDL to include the relative file (instead of the remote one) , but i'd prefer to avoid this , because the file is a third party service WSDL.

Thank you in advance for any hint.

回答1:

I think I had the same problem and below is how I solved it using java -D option

java -Dhttp.proxySet=true -Dhttp.proxyHost={value} -Dhttp.proxyPort={value} org.apache.axis.wsdl.WSDL2Java {wsdlURL}

See if it helps you. Regards

回答2:

This solution may not work asis depending on the user's installation. There is no mention in the solution of the -Dhttp.nonProxyHosts={list of hosts to exclude} option which may be required if your server running the webservices is local and there are references to xml files hosted outside your environment or if your proxy is not setup to answer local requests.
