Custom struts2 tag?

I want to write my own struts2 tag, which has a separate class of actions for itself and can be called from different jsp pages.

Sort of:

<s:writetext type="aaa" parentid="xxx" parentname ="yyy" height ="50" width ="125" />

Is it possible? Please help, I am very new to this, and googling about this did not help.

Thanks Aditya

This old question has become relevant for me this week, when some existing code is being reviewed. Apart from tbruyelle's answer , this was the most useful link for me:

http://bodez.wordpress.com/2009/03/13/customising-struts2-jsp-tags/

In short (1) ,

  • Extend an existing tag (e.g. org.apache.struts2.views.jsp.ui.TextFieldTag )
  • Extend your behavior (e.g. org.apache.struts2.components.TextField )
  • Define a new theme and templates (for example, copy and edit an existing theme in /core/src/main/resources/template )
  • Create a new TLD for a customized version of taglib
  • Deploy it in a web application

struts 2 API can also be useful.

Unfortunately (and surprisingly), there is very little documentation on how to do this, and the javadoc for existing location components is a bit leaner and misleading. Perhaps it is not intended to be used in this way?

Notes

(1) I edited this answer a few years after the initial post to add this summary, matching the answer with SO recommendations. Unfortunately, this was a long time without working with similar code, and I cannot be sure that I have retained the essence of the linked blog, so please refer to the link if it still works.
