Try this. Works for me.
<html:submit property="<%=Constants.SUBMIT %>">
<bean:message key="changePassword.submit"/>
</html:submit>
Where Constants.java contains fixed constants. bean:message can be an
internationalized label which gets displayed to the user.
One other superior approach is to keep all the Constants in a properties
file and write your own PropertyFile manager to show the properties. The
advantage is that if you use the approach , the value is kept in the jsp
page at cmpile time. So if in the future you change Constants.java, the
value will not be reflected in the jsp page(cause it is already kept there
at compile time). Defer this till runtime by using a properties file to
store your contants. So even if you cnage your constants properties file,
you don't have to re-cmpile your jsp pages.
When you use the above approach, check for this name (in name=value) pairs
in your Action class and do your logic...So when the user clicks on the
Submit button, the name=value pair is send. Discard the value and look for
the name...
//Action class
---------------
if( request.getParameter(Constants.SUBMIT) != null )
{
//do something
}

Much thanks for this clearfying hack.
In my opinion we should look for a way to identify the pressed button
without
refering the label, cause this can be change due to internalization (maybe
with
an German locale "<< Prev" Button will be labeled "<< Zur�ck").
May be someone out there knows a way to have an fixed value that will be
passed
back beside the label.
