Scripting variable from ?

[Vandana Gupta/Raleigh/IBM <vg...@us.ibm.com>]

Hi,

Is it possible to get a String from ApplicationResources.properties using
struts:message and put it into  a scripting variable to be used later in
the jsp??

I wished to do the following:

<mytaglib:mytag  name="<struts:message key='mytag.name'/>"  attrib2=..../>

where mytag is a custom tag.
This does not work for a custom tag though it works for a normal HTMl tag.

I tried
<mytaglib:mytag  name="<%=<struts:message key='mytag.name'/>%>"  attrib2
=..../>

also. but  that didn't work either. So I thought I would assign what is
returned by struts:message to a variable say "name" and substitute it using
jsp expression as :

<mytaglib:mytag  name="<%=name%>"  attrib2=..../>

Now the problem is how do I get the value in a variable??
Any help would be greatly appreciated.
Thanks,
Vandana

Hi Vandana,

For very simple cases where I need to reuse the string, mainly related with
JavaScript event handling, I put it in a JavaScript variable and I am able
to reuse it from a JavaScript event:

<script language="javascript">
var msg='<struts:message key="hello.world" />';
</script>

<mylib:printtag onMouseOver="alert(var);" />

But that's not really clean. So I have developped an helper class to pick
messages in the resource file, and I can use it everywhere JSP code is
accepted:

<mylib:printtag msg="<%= LocaleUtil.getMessage("hello.world") %>" />

I don't think you can rely on a custom tag as recursion into attributes is
not permitted.
