I have the following code on my server
public ArrayList<AMI> getAMIs()
{
ArrayList<AMI> amis = new ArrayList<AMI>();
int n;
AMI ami = new AMI();
GetResources amiResourceXML = new GetResources();
try
{
Document amiDom =
XMLParser.parse(amiResourceXML.getAmi());
Element root = amiDom.getDocumentElement();
XMLParser.removeWhitespace(root);
...........
}
catch
{ ......}
return "some value to client"
}
Why do I receive this error below?

Caused by: java.lang.UnsupportedOperationException: ERROR: GWT.create

test case extends GWTTestCase and that GWT.create() is not called from
