I did something vaguely similar a long time ago ... I needed to access the internal IdentityMapManagerHello, I'm building an app using Eclipselink and I would like to have a little servlet that essentially reads the in-memory settings (eg things like what persistence units are configured to which dbs, what cachs statistics can I get, etc) - I've looked through the api for toplink and can't seem to find anything to do this. Any ideas for getting this sort of info? Thx! -Tony to print out which threads were holding onto locks. For EclipseLink, the basic starting point would be: ... import org.eclipse.persistence.sessions.factories.SessionManager; public class EclipseLinkSpyServlet extends HttpServlet { public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { ServletContext sctx = getServletContext(); sctx.log("EclipseLinkSpyServlet - doGet"); response.setContentType("text/html"); PrintWriter pw = response.getWriter(); pw.println("<html><body><head><title>EclipseLinkSpyServlet</title></head>"); pw.println("<body><h1><center>EclipseLinkSpyServlet</center></h1><br>"); // key is String name of session, value is (obviously) a Session Map sessions = SessionManager.getManager().getSessions(); For each session, you can ask it for its org.eclipse.persistence.sessions.Login via getDatasourceLogin() which has a lot of database information. --
