but i don't understand the data structure to hold the users. When you
get the ResultSet from mysql, how do you put it into the list? Without
using hibernate or similar, i've tried with several collections, for
example a <String >, Map <String><String>. The first string holds the
name or user id, and the map holds attribute-value pair. No success, i
think that is a bad solution.

and another question: i need the user id be passed to another action as
a parameter. I've tried with a s:form and a hidden field, something like
<input type="hidden" value="<s:property>"> is the idea. It's about an
online shop, and i'm having problems with:

1.- listing products from mysql
2.- adding products to the cart (from a mysql products list

i'm a little newbie with struts.....

Thanx for this post. This method is pretty simple and very useful.

Login->Wait Interceptor->Menu/Fail.jsp

I added Interceptor in Struts.xml


  <action name="doLogin" class="validatorlogin.Login">
       <interceptor-ref name="completeStack" />
       <interceptor-ref name="execAndWait" />            
       <result name="wait">Wait.jsp</result>
       <result name="success">menudemo.jsp</result>
       <result name="error">Fail.jsp</result>
    </action>



When i run the project,
After Submitting Login.jsp ,Wait.jsp is rendered after that i[b]t throws
Null pointer Exception instead of Menu.jsp[/b]



With reference to
http://struts.apache.org/2.0.6/docs/execute-and-wait-interceptor.html
http://struts.apache.org/2.0.6/docs/execute-and-wait-interceptor.html

You didn't attach the action source code, but I guess you are not
instantiating the Map before the ParameterInterceptor is executed. I
can think of 3 choices to do that:

1) instantiate the Map in the same place you declare the instance variable:
 Map<String, List<Object> textMap = new HashMap<String, List<Object>();

2) instantiate the Map inside a prepare method (the action must
implement Preparable interface)
public void prepare() {
  textMap = new HashMap<String, List<Object>();
}

3) get the (not null) instance from another place inside in the Map
getter & setter, for example, from session scope:
public Map<String, List<Object> getTextMap() {
  return (Map<String, List<Object>) sessionMap.get("themap");
}

Hi

<interceptor-ref name="sampleInterceptorStackIncludingDefaultStack">
 
          d-\d+?-[sop]
 
</interceptor-ref>

Instead of applying the above pattern, apply the following in struts.xml

its easy and simple to resolve the problem of ( Inappropriate OGNL
expression d-345234)

 <interceptor name="params"
   class="com.opensymphony.xwork2.interceptor.ParametersInterceptor"/>

I don't know what freemarker wants to say.
Does anyone have a suggestion?

Please post the S2 version number, the <s:select> tag you are using
together with the action code to initialize the select list/map.
