Validation of XML instance failing as reference to supported schema is not found.

Hi All,

 

I have three schemas(xsds) Java.xsd, database.xsd, base.xsd.

Iam importing java.xsd and database.xsd into base.xsd.

 

I created an XML instance using base.xsd, which looks like below

 

Ei2d.xml (XML instance)

==========

<?xml version="1.0" encoding="UTF-8"?>

<ei2d:Ei2dLibType xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:ei2d="http://www.cisco.com/gmi/ei2d">

<ei2d:managedResourceDef>

<ei2d:managedResource xmlns:ei2d="http://www.cisco.com/gmi/ei2d"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:database="http://www.cisco.com/gmi/ei2d/database"
name="ThinkPositive">

      <ei2d:reference database:checking="Swayam"/>

      <ei2d:configData>

        <ei2d:attribute xsi:type="ei2d:ConfigAttributeType"
javaAccessType="public" name="itWorks" />

      </ei2d:configData>

    </ei2d:managedResource>

</ei2d:managedResourceDef>

</ei2d:Ei2dLibType>

 

Now when I try to validate it using XMLSpy, Iam seeing below error

 

"Unable to locate a reference to a supported schema type(DTD, W3C
Schema)within this document instance"

 

It will be of great help if anyone can please help me out regarding how
to solve this problem.

The base.xsd, Java.xsd and database.xsd are as given at the end of this
email

 

Thanks,

Swayam
