Re: use EL in Struts 1.1

Hi Rajesh
In layout page in a tile page am passing a querystring(parameter) as
?CategoryId=3
If i need to display can i just add it as
<img src="images/category${request.parameter.CagegoryId}.gif" width="120"
height="40">
 

I'm afraid not since the method signature is 
request.getParameter(String) and what you are trying to do is 
request.getParameter().getCagegoryId().getGif(), which you cant do since 
the getParameter method takes a String.
One way, not so pretty would be to use <%%> with casts and such:
 <% ((CagegoryObject) 
request.getParameter("CagegoryId")).getCagegoryId().getGif()%>.

Another way would be to use a bean:define tag (be sure to include the 
bean tag lib before trying this):
 <bean:define id="cagegory" type="CagegoryObject" 
value="<%request.getParameter("cagegoryId")%>" />

then you can write
 <img src="images/category${cagegory.cagegoryId.gif}" width="120" 
height="40" />

Replace the CagegoryObject with whatever Object cagegoryId is a type of...
I haven't tested this, but it should work...
