Re: XPath
What object is "root"? Is it a company instance? If so, this should work:
root.get("departments/employees");
If it's not, then maybe you need something like this:
root.get("company/departments/employees");
How did you load the instances?

That works fine. What I want is all the employees irrespective of the

"root" is the company instance. The first expression results in a
ClassCastException and the second returns a null.
This is what my graph looks this:
<?xml version="1.0" encoding="ASCII"?>
<sdo:datagraph xmlns:company="company.xsd" xmlns:sdo="commonj.sdo">
<company:CompanyType>
<departments location="Test Location - [0]">
<employees name="Test Name - [0][0]"/>
</departments>
<departments location="Test Location - [1]">
<employees name="Test Name - [1][0]"/>
<employees name="Test Name - [1][1]"/>
</departments>
</company:CompanyType>
</sdo:datagraph>
created in my test case with SDOUtil.createDataGraph() and
DataObject.createDataObject for the rest of the containment.
