JBoss Portal supports the integration of Google gadgets and Netvibes (UWA compatible) widgets out of the box. This integration allows you to display the content of the widget within a portlet. Both types can be added in the administration interface by editing the 'Page Layout' of a page or in the configuration of the users dashboard when selecting the appropriate 'Content type'.
It is possible to modify certain behavior of caching and fetching widgets by changing the init-param values of the portlet.
Connection timeout used for the directory lookup in milliseconds.
Time in minutes for which a widget should be cached. After this time the cached widget information will be deleted and fetched again when the information are needed.
Times in minutes for which a directory query should be cached. After this time the cached query information will be deleted.
This parameter defines if all widgets from a directory lookup should be fetched at the time of the query or not. The default values is false. This means that widgets are only fetched on demand - when the information is really needed.
The parameter for both widget types can be changed identically in either:
...
<portlet>
...
<init-param>
<name>connectionTimeout</name>
<value>5000</value>
</init-param>
<init-param>
<name>widgetExpiration</name>
<value>360</value>
</init-param>
<init-param>
<name>queryExpiration</name>
<value>60</value>
</init-param>
<init-param>
<name>fetchWidgetsOnDirectoryLookup</name>
<value>false</value>
</init-param>
...
</portlet>
...
For Netvibes widgets it is also possible to define a init-param called defaultHeight to set a specific default height if no height attribute is defined by the widget itself. The default value is 250.
