Hi. There may be no standard, but this code works just fine for us. Define a class to which all portlets have access and change it according to your needs:


import java.util.Hashtable;

public class InterPortletCommManager {

  private static InterPortletCommManager thisMgr = null;
        private Hashtable something;

  private InterPortletCommManager() {
    try {
        something = new Hashtable();
                        // do any initialization of local variables here
    }
    catch (Exception ex) {

    }
  }

  public static InterPortletCommManager getInstance() {
    if (thisMgr == null) {
      thisMgr = new InterPortletCommManager();
    }
    return thisMgr;
  }

        public Object getObject(String portletId) {
            // retrieve an Object by using a portlet ID
                return something.get(portletId);
        }

        public void setObject(String portletId, Object someObject) {
            // use the ID of a portlet as a key for the object to be stored
                something.put(portletId, someObject);
        }

}

with InterPortletCommManager.getInstance() all portlets have access to the Vector "something". Of course you can create other methods and other objects to use amongst all portlets.

Hope it helps. Regards, dj
