There is no method in struts to directly write a numeric value into a field (hidden or not). 
 
What you could do is this: 
 
&lt;html:hidden property=&quot;newSomeNumberVariableObject&quot; value =&quot;&lt;%= someNumberVariable.toString() %&gt;&quot;/&gt; 
 
That way you don't have to change any classes... only the jsp has to be modified. In HTML there are only string values... that is probably the reason why there is no setter for a numeric value. &nbsp;:-) 
 
Hope this helps.

Hi 
I am trying to pass a javascript variable of type long to and struts HTML tag hidden object using the following JSP page code. 
 
&lt;% 
long someNumberVariable = 1234567; 
%&gt; 
&lt;html:hidden property=&quot;newSomeNumberVariableObject&quot; value =&quot;&lt;%=someNumberVariable%&gt;&quot;/&gt; 
 
if someNumberVariable is of type String then it works ok. &nbsp;if it is of type long then I get the following error 
 
cannot resolve symbol 
symbol &nbsp;: method setValue (long) 
location: class org.apache.struts.taglib.html.HiddenTag 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; _jspx_th_html_hidden_2.setValue(someNumberVariable); 
 
I would prefer to pass the variable in as a long type rather than a String as it saves me doing casting in some class files. 
 
Thanks

JavaScript is a dynamic, object-based language commonly used for client-side scripting in web browsers. Recently, server side JavaScript frameworks have also emerged. JavaScript runs on nearly every operating system and  in almost every mainstream web browser.
