dynamic arg0 in bean:message?

Hi,

What I want to do is something like this:

<bean:message key="error.minCharacters"
  arg0="<bean:write name="globals" property="minChars" />" />

or

<bean:message key="error.minCharacters"
  arg0="<%=minChars%>" />

Where arg0 is the result of a bean property, but I can't seem to get it 
to work. If I hard-code the value

<bean:message key="error.minCharacters" arg0="20" />

It works, but it kinda defeats the purpose.

What am I doing wrong, or is there a better way to accomplish this?

Thanks
--
Frank

Well, the best way is probably to use the Struts-EL tag library, which will
allow you to do this:

 <bean:message key="error.minCharacters" arg0="${globals.minChars}" />

Your first attempt failed because you can't nest custom tags in custom tag
attributes.

Your second attempt failed (probably) because your scriptlet variable
"minChars" was not declared, or set to the value of your bean property.

Thanks everyone! Since I had a jsp:useBean in the page already, I was able to do 
the following:

<%=\"\"+globals.getMinChars()%>

Re: dynamic arg0 in bean:message?

Your first example is invalid :

<bean:message key="error.minCharacters"
   arg0="<bean:write name="globals" property="minChars" />" />

A JSP tag cannot be used as attribute value of another tag (XML syntax)

This should work :

<bean:define id="minChars" name="globals" property="minChars" type="String"/>
<bean:message key="error.minCharacters"  arg0="<%=minChars%>" />

Either escape the double quotes ("<bean:write name=\"globals\"
property=\"minChars\" />" ) or use single quotes ("<bean:write
name='globals' property='minChars' />" ).
