I did not want to derive my taglib from BeanTagLibrary, because:

1) I dont like to be closely coupled to an external library, which only supplies optional features that are not at the core of my lib.

2) the above can also be rephrased as a OO design aspect. My library "is not a BeanTagLibrary". It has a completely different purpose. For example, by inheriting from BeanTagLibrary, it would suddenly support the "beandef" tag, which is completely alien to its function.

after all, inheritance is only available once, and therefore should be used with caution..

Hi,

is there a way to do this:

<mytag class="myClass">
  <someTag someAtt="dada>
    <anotherNestedElement att="dada"/>
  </someTag>
</mytag>

where <mytag> comes from a library which is not derived from
BeanTagLibrary or any other Library, and the other tags are not defined
in any library.

The result should be that from the nested tags an object hierarchy is
created, and the root object supplied to the mytag object through the
setSomeTag() method.

Right now if you created your own library, deriving from BeanTagLibrary and
registered "mytag" as a possible root tag, it'd all just work. However you
did say...


where <mytag> comes from a library which is not derived from
BeanTagLibrary or any other Library

why do you have this restriction? Is it namespaces that you don't want to
expose to the end user? You can always register that the empty namespace
binds to your tag library and it'd just work.

e.g.

public class MyTagLibrary extends BeanTagLibrary {
    public MyTagLibrary() {
        registerBean( "mytag", MyDefaultBean.class );
    }
}
...

JellyContext context = new JellyContext();
context.registerTagLibrary( "", new MyTagLibrary() );
context.runScript( "my.jelly" );

then the script that you supplied would just work.
