| − | Here is a list of properties that ZK depends on.
| + | {{ZKConfigurationReferenceHeadingToc}} |
| − | | |
| − | == How to Define ==
| |
| − | To define a library property, you can configure it in <code>WEB-INF/zk.xml</code>.
| |
| − | [[ZK Configuration Reference/zk.xml/The library-property Element | The library-property Element]] for more information. For example,
| |
| − | | |
| − | <source lang="xml">
| |
| − | <library-property>
| |
| − | <name>org.zkoss.zul.Button.mold</name>
| |
| − | <value>trendy</value>
| |
| − | </library-property>
| |
| − | </source>
| |
| − | | |
| − | Alternatively, you can define it as a system property with the configuration file of your Web server, though the system property affects the whole system, not just one Web application.
| |
| − | | |
| − | == <i>class</i>.mold ==
| |
| − | Default: none | |
| − | [Since 5.0.0]
| |
| − | | |
| − | It specified the default mold of the specified component. The property name is a concatenation of the class name of the component and <tt>mold</tt>. For example, the property for the button's default mold is called <tt>org.zkoss.zul.Button.mold</tt>.
| |
| − | | |
| − | <source lang="xml">
| |
| − | <library-property>
| |
| − | <name>org.zkoss.zul.Button.mold</name>
| |
| − | <value>trendy</value>
| |
| − | </library-property>
| |
| − | </source>
| |
| − | | |
| − | == org.zkoss.util.label.classpath.charset ==
| |
| − | Default: UTF-8
| |
| − | [since 3.6.0]
| |
| − | | |
| − | It defines the charset used to encode i3-label.properties if the file is located in classpath.
| |
| − | | |
| − | == org.zkoss.util.label.web.charset ==
| |
| − | Default: UTF-8
| |
| − | [since 3.6.2]
| |
| − | | |
| − | It defines the charset used to encode i3-label.properties if the file is located in a Web application.
| |
| − | | |
| − | Prior to 3.6.2, the property is called org.zkoss.util.label.WEB-INF.charset.
| |
| − | | |
| − | == org.zkoss.util.label.web.location ==
| |
| − | Default: /WEB-INF/i3-label.properties
| |
| − | [Since 3.6.2]
| |
| − | | |
| − | It specifies where i3-label.properties are named and located.
| |
| − | | |
| − | == org.zkoss.util.logging.realCauseBriefly ==
| |
| − | Default: 6
| |
| − | [Since 3.6.1]
| |
| − | | |
| − | It defines the number of lines to log an error message.
| |
| − | | |
| − | If nonpositive is specified, the full stack traces are logged. Notice that # of lines don't include packages starting with <tt>java</tt>, <tt>javax</tt>, <tt>sun</tt>, or <tt>bsh</tt>.
| |
| − | | |
| − | | |
| − | == org.zkoss.util.logging.warningBriefly ==
| |
| − | Default: 3
| |
| − | [Since 3.6.1]
| |
| − | | |
| − | It defines the number of lines to log a warning message.
| |
| − | | |
| − | If nonpositive is specified, the full stack traces are logged. Notice that # of lines don't include packages starting with <tt>java</tt>, <tt>javax</tt>, <tt>sun</tt>, or <tt>bsh</tt>.
| |
| − | | |
| − | == org.zkoss.web.classWebResource.cache ==
| |
| − | Default: true
| |
| − | [Since 3.6.3]
| |
| − | | |
| − | It specifies whether to allow the browsers to cache the so-called class Web resources<ref>Class Web resources are resources that can be loaded by use of "~./*".</ref>.
| |
| − | | |
| − | By default, it is true. It means the static class Web resources are cached in browsers if possible, unless you upgrade ZK to a different version.
| |
| − | | |
| − | Notice the you can control the immutable period of the CSS files of class Web resources with
| |
| − | another property called <code>org.zkoss.web.classWebResource.cache.CSS.hours</code>.
| |
| − | | |
| − | If you are developing a component, it is better to turn it off (so you can force browser to load modified CSS and JS files by pressing F5).

| − | == org.zkoss.web.classWebResource.cache.CSS.hours ==
| |
| − | Default: 8760
| |
| − | [Since 3.6.3]
| |
| − | | |
| − | It specifies the number of hours in that period the CSS files of class Web resources won't be changed.
| |
| − | | |
| − | By default, it is 8760 (the same as other class Web resources). Notice that the resource is reloaded. If you want to turn off the cache of the CSS files of class Web resources, you can specify a non-positive value.

| |
| − | | |
| − | == org.zkoss.web.classWebResource.cache.etag ==
| |
| − | Default: false
| |
| − | [Since 5.0.1]
| |
| − | | |
| − | It specifies whether to use ETag to detect and return 304 for matched resource.
| |
| − | | |
| − | If turned on, the cached resource won't be reloaded if the user presses F5 to reload.
| |
| − | | |
| − | == org.zkoss.web.util.resource.dir ==
| |
| − | Default: <i>none</i>
| |
| − | [Since 5.0.0]
| |
| − | | |
| − | It specifies a directory, where ZK will load the so-called Class-Web Resources (CWR), in addition to the class path. CWR includes JavaScript files, CSS files, and other resources that are specified in the form of <tt>~./xxx</tt>.
| |
| − | | |
| − | By default, ZK only searches the class path for the required CWR. By specifying a directory here, ZK will search the directory first and then the class path. It implies a developer can override the default behavior by providing a file with the same name.
| |
| − | | |
| − | Notice: don't put security sensitive files in the directory specified here, since they can be accessed externally.
| |
| − | | |
| − | For example, assume we have a JavaScript package called <tt>foo.great</tt> and we want to put it to <code>WEB-INF/cwr</code>. Then, we have to specify the following in <tt>WEB-INF/zk.xml</tt>:
| |
| − | | |
| − | <source lang="xml">
| |
| − | <library-property>
| |
| − | <name>org.zkoss.web.util.resource.dir</name>
| |
| − | <value>/WEB-INF/cwr</value>
| |
| − | </library-property>
| |
| − | </source>
| |
| − | | |
| − | Then, you can place <tt>zk.wpd</tt> and required JavaScript files under the <tt>WEB-INF/cwr/js/foo/great</tt> directory.
| |
| − | | |
| − | == org.zkoss.web.servlet.http.URLEncoder ==
| |
| − | Default: <code>javax.servlet.http.HttpServletResponse.encodeURL</code>
| |
| − | [Since 5.0.0]
| |
| − | | |
| − | It specifies the class used to encode URL by including the session ID and the Servlet's context path, if necessary. The specified class must implement the <javadoc type="interface">org.zkoss.web.servlet.http.Encodes.URLEncoder</javadoc> interface.
| |
| − | | |
| − | If the clients are far away from the server, you might override this class by encoding the URL of JavaScript and CSS files with a server nearby. Thus, it could shorten the time to load a page. For more information, please refer to [[ZK_Developer's_Reference/Performance_Tips/Load_JavaScript_and_CSS_from_Server_Nearby|Performance Tips]].
| |
| − | | |
| − | In a sophisticated environment, e.g., [http://en.wikipedia.org/wiki/Reverse_proxy Reverse Proxy], the encoded URL might have to be prefixed with some special prefix. To do that, you can implement the <javadoc type="interface">org.zkoss.web.servlet.http.Encodes.URLEncoder</javadoc> interface, and then specify the class with this library property.
| |
| − | | |
| − | == org.zkoss.zk.ui.EmulateIE7 ==
| |
| − | Default: false
| |
| − | [since 5.0.2]
| |
| − | | |
| − | It specifies whether to make Internet Explorer 8 running in IE7 compatible mode. It is used if some of your JavaScript code doesn't work well in IE8.
| |
| − | | |
| − | Refer to [http://blogs.msdn.com/ie/archive/2008/06/10/introducing-ie-emulateie7.aspx Introducing IE=EmulateIE7]
| |
| − | | |
| − | == org.zkoss.zk.ui.event.EventQueueProvider.class ==
| |
| − | Default: <i>none</i> (it implies <javadoc>org.zkoss.zk.ui.event.impl.EventQueueProviderImpl</javadoc>)
| |
| − | [since 5.0.0]
| |
| − | | |
| − | It specifies the name of the class used to provide the event queue. The class must implement the <javadoc type="interface">org.zkoss.zk.ui.event.impl.EventQueueProvider</javadoc> interface.
| |
| − | | |
| − | == org.zkoss.zk.ui.input.grouping.allowed ==
| |
| − | Default: <i>true</i>
| |
| − | [since 5.0.5]
| |
| − | | |
| − | Turn on/off whether the user is allowed to key in the grouping character when entering a number. The grouping character depends on the Locale. For example, it is a comma in English, and a dot in Germany. By default, ZK will allow the user to key in the grouping characters and the grouping characters are simply ignored when the input is parsed to a number.
| |
| − | | |
| − | Some people still get confused whether the application considers a comma as a decimal point or not, when he is new to the application. By disabling the entering of the grouping character will help in this case.

| |
| − | Default: <i>none</i>
| |
| − | [since 5.0.4]
| |
| − | | |
| − | It specifies the name of the class used to load the page definitions. The class must implement the <javadoc>org.zkoss.util.resource.Loader</javadoc> interface and it must have a constructor as follows.

| − | Default: <i>false</i> (i.e., UUID recycle is enabled)
| |
| − | [since 5.0.3]
| |
| − | | |
| − | It specifies whether to disable the recycle of UUID. By recycling UUID will reduce the memory use of the browser. It is enabled by default.
| |
| − | | |
| − | == org.zkoss.zk.ui.sys.XMLResourcesLocator.class ==

| |
| − | | |
| − | * Notice that you can specify the property in <code>WEB-INF/zk.xml</code>, since it is too late. Rather, you have to specify in the server's configuration (as a system property).

| − | [Enterprise Edition]
| |
| − | [Since 3.5.0]
| |
| − | | |
| − | It specifies the name of the class that will be notified when a file download is happening. The class must implement the <javadoc type="interface">org.zkoss.zkmax.zul.FiledownloadListener</javadoc> interface.
| |
| − | | |
| − | A developer usually uses it to reject a download if the user tried to resume it in an unacceptable situation. For example, a developer can limit the user from downloading within upcoming 24 hours.
