jakarta.el.ELResolver

jakarta.servlet.jsp.el.ScopedAttributeELResolver

org.opencms.jsp.util.CmsJspSimpleELResolver

public class CmsJspSimpleELResolver
extends jakarta.servlet.jsp.el.ScopedAttributeELResolver

Does basically the same as ScopedAttributeELResolver, but always marks top-level properties as resolved even if no value was found.

This is meant to bypass ImportELResolver (in Jakarta EE 10 and later), which comes later in the resolver chain and would be normally triggered later for an unresolved property, but incurs a heavy performance penalty on Jetty, especially in combination with the Mercury template, where potentially undefined top-level variables are used a lot.

Using this means that the functionality provided by ImportELResolver will not be available in OpenCms JSPs.
