Portlet Preferences to no logged users

Question

Hi people,
I created a JSR168 Portlet with view and edit mode. I put into my webcenter custom application. I go to edit mode to set some preferences from portlet, to do this I need be logged in.
The problemn is that just logged users can view the preferences that I set. If I logged off I can't saw any preferences.
I tried use edit_defaults mode, but don't work fine.
Can someone help me please?

Hey sorry for the delay but here it goes :)
Think you should get enough information by this example to complete what you want, else just ask :)
So first of all you will need to add a parameter definition to the oracle-portlet.xml
THis is what you should add after the portlet-name in the oracle-portlet.xml:
<navigation-parameters>
            <name>param1</name>
            <type xmlns:xsd="http://www.w3.org/2001/XMLSchema">xsd:string</type>
            <label xml:lang="en-US">First Parameter</label>
            <hint xml:lang="en-US"/>
        </navigation-parameters>Normaly you shouldn't do anything extra in order to show those parameters and store them. Everything from here is managed by your consuming application. Notice here that the consuming can only be of the webcenter kind so a custom webcenter application or webcenter spaces due to the oracle specific implementation of the parameters. This gets standardized by the JSR286 but webcenter doesn't support this yet...
Also notice that when you change something to the oracle-portlet.xml or portlet.xml you should refresh the registration in your consuming application AND remove the old portlet from your page and replace it by a new one. Otherwhise you will not see the new parameter.
So when you added this to the oracle-portlet.xml and refresh the registration you should see the parameter in the portlet parameter tab when you click the pencil on the portlet in edit mode. Note that you should have customize rights in order to do this.
Parameters that you set their are not stored for the user, they are application wide stored so if for example admin1 sets a value and admin2 changes it to another value, the last value will overwrite the first one.
The next thing you should need to know is how to get the parameter from your code.
This is queiet easy... THe PortletRequest has the getParameter function that will return the value:
in your backing bean you can write this:
        String param = "";
        PortletRequest request = (PortletRequest)FacesContext.getCurrentInstance().getExternalContext().getRequest();
        param = request.getParameter("param1");
       if(param.equals(""))
           param = "No value for the param has been set yet";
       return param;In fact that's all you need to know for implementing parameters.
In case something is not clear or you have problems, just ask.
