Check out the MadvocConfig class: https://github.com/oblac/jodd/blob/master/jodd-madvoc/src/main/java/jodd/madvoc/component/MadvocConfig.java#L66

By default, ServletConfigInterceptor is the one that those all the @In and @Out magic for you. When you specify the:

@InterceptedBy(EchoInterceptor.class)
public String book() {

you simply didn't use the ServletConfigInterceptor but just the echo one.

Fix

Either add the default configurator explicitly:

@InterceptedBy(EchoInterceptor.class, ServletConfigInterceptor.class)
public String book() {

OR specify all default ones

@InterceptedBy(EchoInterceptor.class, DefaultWebAppInterceptors.class)
public String book() {

OR add echo to default ones:

madvocConfig.setDefaultInterceptors(ew Class[] {EchoInterceptor.class, ServletConfigInterceptor.class};

OR do the same in madvoc.props

OR create new ActionInterceptorStack

and so on :)
