It configures the interpreters to interpret the zscript codes. The allowed child element is language-name and interpreter-class. You might have multiple zscript-config elements in one zk.xml.
<zscript-config>
<language-name>Java</language-name><!-- case insensitive --!>
<interpreter-class>my.MySuperJavaInterpreter</interpreter-class>
</zscript-config>
Note: Unlike most other configurations defined in WEB-INF/zk.xml, the definitions defined in zscript-config are applied to all Web applications sharing the same zk.jar.
In other words, the scripting language defined here are visible to all Web applications sharing the same zk.jar. Furthermore, it may cause errors in another Web application, if the classes or resources are available only in the Web application defining this.
Thus, if it is an issue, just put zk.jar and relevant ZK libraries under the WEB-INF/lib directory.
[Required]
It specifies the language name. It is case insensitive. The previous implementation with the same language name will be replaced if any.
[Required]
It specifies the implementation class. It must implement the org.zkoss.zk.scripting.Interpreter interface. Instead of implementing it from scratch, you can derive from the org.zkoss.zk.scripting.util.GenericInterpreter class. If you want to support the hierarchical scopes (i.e., one interpreter scope per namespace), it can also implement the org.zkoss.zk.scripting.HierachicalAware interface.
