Hello.
I use PortletPreferences class,this code to store preferences in the action(ConfigAction implements ConfigurationAction):
preferences().setValue("greeting", greeting);
preferences().store();

,and this code to retrieve the data in the jsp page:
String greeting = preferences.getValue("greeting", "no peferences");
But I dont get the values that I stored it.
How can I use the preferences successfully.
Thank you.

Are there any errors in your console log or catalina.out file?

I am also having problems using preferences.store() in 6.1 is that the version you are using? I ma be raising a jira ticket tomorrow if I cannot crack it.

to help more perhaps a full snippet of code showing how the preferences were created in the first place.

If you are using ConfigurationAction retrieve portletPreferences like this in java

1String portletResource = ParamUtil.getString(
2            actionRequest, "portletResource");
3
4        PortletPreferences preferences =
5            PortletPreferencesFactoryUtil.getPortletSetup(
6                actionRequest, portletResource);
7preferences().setValue("greeting", greeting);
8preferences().store();


And in jsp use this
 1
 2PortletPreferences preferences = renderRequest.getPreferences();
 3
 4String portletResource = ParamUtil.getString(request, "portletResource");
 5
 6if (Validator.isNotNull(portletResource)) {
 7    preferences = PortletPreferencesFactoryUtil.getPortletSetup(request, portletResource);
 8}
 9String greeting = preferences.getValue("greeting", "no peferences");


Regards,
Sandeep
