XSQLActionHandler extracting XML from ViewObject not displaying on XSQL pag

Question

I have the following XSQLActionHandler for a STRUTS project which is supposed to extract the XML from a view object. When I call this from a xsql page I get nothing. I have examined the Node (n) and have seen that it does get XML but after I assign it to root nothing shows up on the XSQL page. Any ideas about what might be wrong?
package XSQLActionHandler;
import oracle.xml.xsql.XSQLActionHandlerImpl;
import oracle.xml.xsql.XSQLServletPageRequest;
import oracle.xml.xsql.XSQLPageRequest;
import org.w3c.dom.Node;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.ServletContext;
import oracle.jbo.html.BC4JContext;
import oracle.jbo.ViewObject;
import oracle.jbo.XMLInterface;
import oracle.xml.parser.v2.XMLNode;
import oracle.jbo.html.databeans.XmlData;
public class ActionHandlerTestVO extends XSQLActionHandlerImpl {
public void handleAction(Node root) {
XSQLServletPageRequest xspr = (XSQLServletPageRequest)getPageRequest();
HttpServletRequest request = xspr.getHttpServletRequest();
BC4JContext context = BC4JContext.getContext(request);
XSQLActionHandlerModuleImpl appmod = (XSQLActionHandlerModuleImpl) context.getApplicationModule();
ViewObject vo = context.getApplicationModule().findViewObject("DisciplineView1");
Node n = (Node) vo.writeXML(1, XMLInterface.XML_OPT_ALL_ROWS);
root=n;

Answer 1

You need to append your generated content as a child of "root".
It's best practice if you call adoptNode() on it first before appending it.
Like this:
XMLDocument rootDoc = (XMLDocument)root.getOwnerDocument();
rootDoc.adoptNode(n);
root.appendChild(n);
