BPM 11g Hello World Application Error

Question

I am going through step-by-step tutorial on creating Hello World Application BPM 11g where I am running into WSDL Read Error message. The link for this tutorial is here:
Building Your First Process with Oracle BPM 11g
Error occurs at chapter "Enhancing the Basic Hello World Process" -> Adding a Business Rule -> Step 5.
After creating Data Associations for input/output under Implementation dialog for "Review Needed" business rule and clicking on OK of the Properties dialog, I get following error message(please click on the link to see screenshot of error message):
https://drive.google.com/file/d/0B1YDzO9g_MoLNkVTazdXTHp2UVE/edit?usp=sharing
Let me know if you have trouble accessing this link.
Basically the error is about not able to find decision service wsdl file:
Error while reading wsdl file:
ReviewRules_DecisionService_1.wsdl file not found
Also get same error for HelloRules_DecisionService_1.wsdl file not found.
I am not sure whether this file should be automatically generated when performing data associations and implementation of the business rule in the wizard.
Please let me know what could be going wrong here. I tried going through this tutorial multiple times but get stuck at this step.

I looked at the two XSDs the Hello World tutorial had you using.  This is what is causing your error.
Here's an XSD that will work for the tutorial with 11.1.1.7.  Notice I put both the "hello" and "review" objects in the one XSD so you just have to use the one XSD. 
<?xml version= '1.0' encoding= 'UTF-8' ?>
<schema xmlns="http://www.w3.org/2001/XMLSchema" xmlns:xsd="http://www.w3.org/2001/XMLSchema"
     xmlns:qt="http://www.mycompany.com/ns/hw" targetNamespace="http://www.mycompany.com/ns/hw"
     elementFormDefault="qualified">
    <element name="HelloObject" type="qt:HelloObjectType"/>    
    <complexType name="HelloObjectType">
        <sequence>
            <element name="date" nillable="true" type="dateTime"/>
            <element name="message" nillable="true" type="string"/>
            <element name="greeting" nillable="true" type="string"/>
        </sequence>
    </complexType>
    <element name="ReviewObject" type="qt:ReviewObjectType"/>
    <complexType name="ReviewObjectType">
        <sequence>
            <element name="review" nillable="true" type="string"/>
            <element name="reason" nillable="true" type="string"/>
        </sequence>
    </complexType>
</schema>
Hope this helps,
