You've possibly cut too much of your schema out, but I can't see where 
ConfigAttributeType is defined in your schemas.  We would need to see what 
that is defined as in the schema with targetNamespace 
http://www.cisco.com/gmi/ei2d.  I can't see where some of the other types 
are defined either.

Thanks,

Pete.

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
