OPA Data Adaptor Plugin importing XML to a session in Load

Question

Hi,
I am writing a generic plugin which saves the session data as XML using SessionUtils.exportSession. This works fine as I have the session as an argument in the Save method. How can I get the session in the load method to do the import ?
Sample code below.
cheers
Tony
  public String save(SecurityToken token, String caseID, InterviewSession session) {
          Session ruleEngineSession = session.getRuleSession();
          StringWriter xmlWriter = new StringWriter();
          SessionUtils.exportSession(ruleEngineSession, xmlWriter);
          System.out.println("*****DA_save:XML:" + xmlWriter.toString());
          savedValues.put(caseID, xmlWriter.toString());
  public InterviewUserData load(SecurityToken token, String caseID,
      InterviewRulebase rulebase) {
          StringReader xmlReader = new StringReader((String)savedValues.get(caseID));
          SessionUtils.importSession(????????, xmlReader);

Hi Ian,
Many thanks for the reply. If I understand correctly, the issue with this is that it is not generic, i.e. I have to know the attributes and types to insert whereas I would like to be able to load the exported XML, in its entirety, back to the session in the load method... or have I misunderstood ? This is where I thought SessionUtils.import came in, in the same way I use SessionUtils.export to save.
I would also like to store some of the specific data separately, in our own data model, which is the reason for writing the custom plugin, but by default I would like to store the data as is without having to amend the plugin whenever the attributes changed.
cheers
