You can use the following Spring EL construct to evaluate static methods:

<evaluate expression="T(org.hibernate.Hibernate).initialize(yourObject)"/>

See the appropriate Spring EL reference part:

spring-webflow 2 uses OGNL expressions. OGNL allows for static referencing of fields and methods. To utilize it you would want to use the '@' notations.

First you reference the class (with package). You would want to put an @ before the package and class name and an @ before the method call. With hibernate it would look like

<evaluate expression="@org.hibernate.Hibernate@initialize()"/>

  • It doesn't work. I get parse error: org.springframework.expression.spel.SpelParseException: EL1041E:(pos 24): After parsing a valid expression, there is still more data in the expression: 'bean_ref(@)' – marioosh Nov 24 '10 at 07:56
