how to set Preferences

[sandeeppujar]

Hello,

What is the best way to set preferences in portlets. Is there some document I can refer to.
I have setup mysql database as the data source to store the preferences.

I am looking to store prefernces
1. as some key - value pair.
2. Per user.

Other question is can I use PortletPreferences interface from the RenderRequest object ?

thanks,
Sandeep

You can use the PortletPreferences.store() method directly. Behind the scenes, JBoss Portal will save your user preferences (values) in table jbp_user_pref_prop_value (if you want to check with your DB GUI tool).

In your portlet you should:

1. obtain a reference to PortletPreferences:

PortletPreferences portletPrefs = portletRequest.getPreferences();

2. update the desired values of the preferences:

portletPrefs.setValue(...) or portletPrefs.setValues(...)

3. Invoke portletPrefs.store().

Thanks ,

I have another question,

If I have a guest user , then how do I save his preferences ?

I have it setup and use portletPrefs.store(), but nothing appears in the database, is there any configuration I am missing.

Below is my code

PortletPreferences pref = request.getPreferences();
pref.setValues(team + PREF_METRIC_LIST, metricsArray);
pref.setValue(team + PREF_ACTIVE_METRIC_LIST, "yes");
pref.store();


Thanks for all the inputs,
Sandeep

could you give a good primary key for a guest user ? if so I can persist it in a database.

The primary key can be "guest" .

I guess PortletPreferences class assumes that there is a current user who
has logged in.
For guest this might not work as guest need not log in but still I might want to store some preferences for him.

Is there a way I can set the user to guest by default and store the preferences for guest ?

thanks,
