I have a problem with my code. I send it with its related xml file in attachment.
I get the error:
java.lang.ClassCastException: org.apache.xerces.dom.DeferredElementNSImpl
at Database2.sample(
at Database2.main(
Exception in thread “main”

AccessListaMe.xml (719 Bytes)

Here is the code.

The reason for the ClassCastException is that the returned value from the following line:

Element accessList = (Element)xmlObject.getElement();

is a org.w3c.dom.Element and the Element accessList in this case is imported from org.jdom.* (line 8 in the source). The reason a org.w3c.dom.Element is being returned is because you have asked to use the TDOMObjectModel when creating the TXMLObjectAccessor.

So you either need to :
1) change org.jdom imports to org.w3c.dom imports;
2) or change the object model to TJDOMObjectModel.

I’m trying your first solution, but i have to change getChildren, in getElementByTagName and i have i insert Nodelist of java.util import, is it correct?


The first solution have to many changes to do. So i try the second changing

accessor = connection.newXMLObjectAccessor(
TAccessLocation.newInstance( collection ) ,
TDOMObjectModel.getInstance() );

accessor = connection.newXMLObjectAccessor(
TAccessLocation.newInstance( collection ) ,
TJDOMObjectModel.getInstance() );
with adding the following import
import com.softwareag.tamino.db.api.objectModel.jdom.*;

and it works!!!
Many Thanks Stuart!!!
