<?variable-resolver class="..."?>
Specifies the variable resolver that will be used by the zscript interpreter to resolve unknown variables. The specified class must implement the org.zkoss.xel.VariableResolver interface.
You can specify multiple variable resolvers with multiple variable-resolver directives. The later declared one has higher priority.
The following is an example when using ZK with the Spring framework. It resolves Java Beans declared in the Spring framework, such that you access them directly.
<?variable-resolver class="org.zkoss.zkplus.spring.DelegatingVariableResolver"?>
Refer to Small Talk: ZK with Spring DAO and JDBC, Part II for more details.
