Portlet Preferences

[12年前 に Ahmed Elbassel によって更新されました。]

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.

Hi

Its old thread, but my reply will helpful to others.

Portlet preferences based on userId
set the value
long companyId=themeDisplay.getCompanyId();
long ownerId=themeDisplay.getUserId();
int ownerType=PortletKeys.PREFS_OWNER_TYPE_USER;

javax.portlet.PortletPreferences preferences = PortalPreferencesLocalServiceUtil.getPreferences(companyId, ownerId, ownerType);
preferences.setValue(key,value);
preferences.setValue(key,value);
preferences.store();

Get the portlet preferences value
preferences.getValue(key, "No Value ");

if you want to set the portlet preferences based on portletId.
Set the value

ThemeDisplay themeDisplay = (ThemeDisplay)resourceRequest.getAttribute(WebKeys.THEME_DISPLAY);
String portletId=themeDisplay.getPortletDisplay().getId();

javax.portlet.PortletPreferences portletSetup =PortletPreferencesFactoryUtil.getLayoutPortletSetup(themeDisplay.getLayout(), portletId);

try {
portletSetup.setValue(key, value);
portletSetup.setValue(key, value);
try {
portletSetup.store();
} catch (ValidatorException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println("value 1.."+portletSetup.getValue(key, "No Value"));
System.out.println("value 2.."+portletSetup.getValue(key, "No Value"));
} catch (ReadOnlyException e) {
e.printStackTrace();
}

Get the Value
portletPrefrence.getValue(key, "No Value");


Hope it will helpful

Thanks,
Ashraf

If you are using ConfigurationAction retrieve portletPreferences like this in java

String portletResource = ParamUtil.getString(
			actionRequest, "portletResource");

		PortletPreferences preferences =
			PortletPreferencesFactoryUtil.getPortletSetup(
				actionRequest, portletResource);
preferences().setValue("greeting", greeting);
preferences().store();

And in jsp use this

PortletPreferences preferences = renderRequest.getPreferences();

String portletResource = ParamUtil.getString(request, "portletResource");

if (Validator.isNotNull(portletResource)) {
	preferences = PortletPreferencesFactoryUtil.getPortletSetup(request, portletResource);
}
String greeting = preferences.getValue("greeting", "no peferences");

Sandeep
