> abstract | Portlet is one which cannot be created directly. It acts as a portlet template, useful for defining common properties for a group of related portlets.
> instance | Portlet is the basic entry. It should provide all the necessary information to create the portlet, at least the classname.
> ref | Portlet is based on an existing <portlet-entry> which can be of any type, including other ref entries. The engine will follow all refs until it finds either an abstract or instance entry, override all parameters found in the these definitions by those in the ref definition's, and then create the portlet using the combined definitions

Element: parameter
> The hidden attribute controls whether the customizer will display the parameter. This element is optional.

> --- | ---
> boolean | Only `true` or `false` are allowed as a value for this parameter
> style | Designates the parameter as having a custom presentation style. The presentation style name is defined as value of [parameter name].style parameter. For example, if parameter named "symbols" is designated with type="style", then the style name is defined as value of "symbols.style" hidden parameter. Each parameter designated as having a custom style, will be displayed in the default portlet customizer using the defined parameter style. For sample parameter styles and instructions on how to develop your own, see javadoc for `org.apache.jetspeed.modules.parameters` package. See below for example registry entry.
> invisible | Parameters with this type are rendered as hidden inputs in the portlet customizer form.
> hidden |
> Allowable values
> false

> Parameter Name | Description
> _display | Initial display state of portlet. This parameter can only be set in PSML. If not present, Default: `normal`
> Value | Description
> --- | ---
> closed | Portlet is closed and not visible
> minimized | Portlet is minimized. Only title is displayed
> normal | Portal and content is displayed
> _showtitlebar | Should the Portlet's title bar be displayed. The title bar includes the Portlet title and the action buttons (Minimize, Maximize, Customize, and Close). When the title bar is disabled, i.e. value = false, the user will only be able to add or remove, if permissions allow, the portlet the customizer. This parameter can be set in PSML or in the .xreg files. This parameter was added in version 1.3a3. If not present, Default: `true`
> Value | Description
> --- | ---
> true | Portlet Title Bar is displayed
> false | Portlet Title Bar is NOT displayed
> _TimeToLive | How long, in milliseconds, should the portlet remain idle in cache. This parameter is used to override the default value. Example: _TimeToLive = 300000 which is 5 minutes (5 * 60 * 1000) and the portlet cached expires every 3 minutes.
> Time | Activity
> --- | ---
> 1:00 | Portlet created
> 1:00 | User Joe displayed the portlet content
> 1:03 | Portlet marked as expired, the portlet's refresh() is called, the portlet is no longer expired
> 1:05 | User Sam displayed the portlet content
> 1:06 | Portlet marked as expired, the portlet's refresh() is called, the portlet is no longer expired
> 1:09 | Portlet marked as expired, the portlet's refresh() is called, the portlet is no longer expired
> 1:12 | Portlet marked as expired. Since the portlet has been idle for 7 minutes, the portlet will be removed from cache.
> This parameter can be set in PSML or in the .xreg files. This parameter was added in version 1.3a3.
> _control | Overrides default portlet control with control specified. This parameter can be set in PSML or in the .xreg files. If not present, default portlet control, as specified by `services.PortalToolkit.default.control`, is used. This parameter was added in version 1.4b2.

Good URLs: `<url>http://jakata.apache.org/jetspeed</url>` Basic URL `<url>http://search.yahoo.com/bin/search?p=jetspeed</url>` 1 Parameter passed `<url>http://search.yahoo.com/search?p=jetspeed&amp;n=100</url>` 2 Parameter passed Bad URLs: `<url>index.html</url>` No protocol, http:// or hostname `<url>http://search.yahoo.com/search?p=jetspeed&n=100</url>` Contains & instead of &amp;. Remote URL caching: Portlet types extending the FileWatchPortlet (for example, NewRSSPortlet), read their remote URLs using the JetspeedCache. JetspeedCache uses DiskCacheDaemon to manage refreshing of these URLs upon their change or expiration. See the DiskCache for further details.
Element: security-ref
> Used by customizer to limit access to this item (portlet, parameter,...)
> Attribute Name | Description
