Steps to reproduce:
================
1. Create a synapse configuration as follows.
<definitions xmlns="http://ws.apache.org/ns/synapse";>
<proxy name="TestProxy">
<target>
<endpoint>
<address uri="http://testb:9000/soap/calculatorImportSchema"/>
</endpoint>
<outSequence>
<send/>
<log level="full"/>
</outSequence>
</target>
<publishWSDL
uri="file:repository/conf/sample/resources/proxy/calculator_import_schema.wsdl"/>
</proxy>
</definitions>
2. Make sure to use a wsdl having schema imports.
i.e:- <xsd:import namespace="http://charitha.org/";
schemaLocation="http://ww2.wso2.org/~charitha/calculator.xsd"/>
(wsdl is attached here with)
3. Run synapse
4. Go to http://localhost/:8080/soap/TestProxy?wsdl
You will get the above exceptions in Synapse console. Note that the URL
'http://ww2.wso2.org/~charitha/calculator.xsd' is publicly accessible.
