XSQL and HttpSession object availability

Question

Hello,
How to access the very convenient unique HttpSession unique ID?
The one we have this way within a servlet:
HttpSession session = request.getSession(true);
System.out.println(session.getId());
Thank You in advance

You can access this easily by writing a custom action handler. Here is the code for a custom action handler that sets the value of the Http Session id into a page parameter named "session-id".
import oracle.xml.xsql.*;
import java.sql.SQLException;
import org.w3c.dom.Node;
import javax.servlet.http.*;
public class GetSessionId extends XSQLActionHandlerImpl {
public void handleAction( Node rootNode ) throws SQLException {
XSQLPageRequest req = getPageRequest();
if (req.getRequestType().equals("Servlet")) {
HttpSession sess =
((XSQLServletPageRequest)req).getHttpServletRequest().getSession(true);
if (sess != null) {
req.setPageParam("session-id",sess.getId());
}Then from within your XSQL page, you can say:
<xsql:action handler="GetSessionId"/>
and then later in the page refer to the parameter named session-id to access it's value as a lexical or bind parameter.
