Difference between <jsp:useBean> and <bean:define> ?

[Anan H. Samiti]

When I define something like the following in my ActionClass (in a Struts/JSP Architecture)

request.setAttribute("myVo", myVoObject);

I could access this object from my JSP page (as far as I know) by declaring a bean like:

<jsp:useBean id="myVo" class="mypackage.myVo" />

resp.

<bean:define id="myid" name="myVo" property="getVo" type="mypackage.myVo" />



But what is the difference?

Is the next html:text tag valid for both declarations?

<html:text name="myidValue" property="myValue" size="10" value="<%= myVo.getMyValue() %>" />

I could access this object from my JSP page (as far as I know) by declaring a bean like:

<jsp:useBean id="myVo" class="mypackage.myVo" />

resp.

<bean:define id="myid" name="myVo" property="getVo" type="mypackage.myVo" />

AFAIU, the main difference between these two is that the first is recognized
in any JSP context. The second requires Struts, which not everyone uses.
