My ActionClass Contains

i am assigining in the following way in to my bean in one of my previous action class


ArrayList alist = new ArrayList();
for (int i=1;i<=30;i++)
{
alist.add(i);
}
atdForm.setAtDate(alist);




my ActionForm contains the below contents

ArrayList atDate = new ArrayList();

public ArrayList getAtDate()
{
return atDate;
}

public void setAtDate(ArrayList altDate)
{
this.atdate = altDate;

}







So now i am trying to generate a DropDown in my jsp




<logic:iterate id="element" name="AtdAForm" property="atdate">
<html:select property="selList">
<html:option name="dateList" value="<bean:write name="element"/>"><bean:write name="element"/></html:option>
</logic:iterate>

Please UseCodeTags when posting code or configuration. Unformatted code and configuration is very difficult to read. You can edit your post to include them by using the button.

you can do something like this

ArrayList alist = new ArrayList();
for (int i=1;i<=30;i++)
{
alist.add(i);
}
request.setAttribute("alist",alist);

then in jsp you can retreive this as given below
<html:select property="selList">
<logic:iterate name="alist" id="element"> // as name is name of attribute in some scope
<htmlption name="dateList" value="<bean:write name="element"/>"><bean:write name="element"/></htmlption>
</logic:iterate>
</html:select>



hope this helps

Sorry for mistake

In JSp It would be something like this

<htmlption name="dateList" value="${dateList.element}"><bean:write name="element"/></htmlption>

javax.servlet.ServletException: org.apache.jasper.JasperException: /GetAttDetails.jsp(115,0) Attribute name invalid for tag option according to TLD
org.apache.struts.chain.ComposableRequestProcessor.process(ComposableRequestProcessor.java:286)
org.apache.struts.action.ActionServlet.process(ActionServlet.java:1913)
org.apache.struts.action.ActionServlet.doGet(ActionServlet.java:449)
javax.servlet.http.HttpServlet.service(HttpServlet.java:617)
javax.servlet.http.HttpServlet.service(HttpServlet.java:717)

but i was able to solve the issue in the following way
