[Jelly] Define Beans

Hello,

I would like to create a bean, which has a complex property.  My Jelly
script looks something like that, but it doesn't work:

---%<------------------------------------

  <define:taglib uri="mytaglib">
    <define:jellybean
      name="beanA"
      className="package.name.BeanA"
      method="execute" />

    <define:bean
      name="beanB"
      className="package.name.BeanB" />
  </define:taglib>
  
  <goal name="hello"> 
  
    <mytaglib:beanB
        var="mybeanb" />
        
    <mytaglib:beanA
        var="myConverter"
        propertyOfTypeBeanB="mybeanb" />  **)
  ....

---%<------------------------------------

**) Jelly tries to set 'mybeanb' as String to 'propertyOfTypeBeanB',
which results in an IllegalArgumentException. 

Is there a way to do something like that with Jelly?

Thanks for any hint,
-Stefan

is more appropriate.

And so it should.

Defining a bean as part of a taglib means that it will call the
execute method when the tag is executing.

If you'd like to create a bean, and store it in a property, the
useBean tag http://jakarta.apache.org/commons/jelly/tags.html#core:useBean
is more appropriate.
