As suggested by others the last time you asked this question, first try
to determine whether it's the the servlet, servletContext or HashTable
that's null.

Hmm, guess you were asking about extending DynaValidatorForm. I must
have been thinking of some other question that was similar to this
one. Anyway, a DynaValidatorForm is a DynaBean, so you can call
set("propertyName", "reset Value") from your reset override method.
These API versions aren't exact, but I don't think these classes have
changed much:

RE: Extending DynaValidatorForm
Thanks David,
But I need sample code. Can u provide it? I got your logic but finding it
difficult to implement. The main problem is how to get the property name at
runtime. I have many forms that extend the DynaValidatorForm.
Thank you,
AM

servlet.getServletContext().getAttribute("userList") is throwing NullPointerException in my sessionDestroyed() method
Hi team,
In my login action I am adding the user who logged in into
hash table and I am putting that hash table in
servlet.getServletContext().setAttribute("") as fallows
Hashtable userList = new Hashtable();
userList.put("username",username);
servlet.getServletContext().setAttribute("userList",userList);
and in my sessionDestroy() method I am removing that user from the
context when his session expires as fallows
HttpSession session = sessionEvent.getSession();
String user = (String) session.getAttribute("username");
System.out.print(" USER "+user);
session.removeAttribute("ServiceNo");
Hashtable userList = (Hashtable)
servlet.getServletContext().getAttribute("userList");
userList.remove(user);
I am getting NullPointerException in this line Hashtable userList =
(Hashtable) servlet.getServletContext().getAttribute("userList");
But I am sure the list in not null;

linking struts2 action to pre-existing pure Java servlet
Hi, I have a servlet which implements some logic based on some URL parameters passed to it. I can invoke this servlet directly from my browser, by simply supplying the parameters thru the URL. http://localhost:8080/myproject/myapplication?param1=value1¶m2=value2 However, I would like to set these parameters thru' the struts.xml ( using ) and thereafter link this servlet ( the servlet simply extends HttpServlet) to the struts action so that it is invoked the same manner as above. any clue on how I can do this. I can get the request parameter values in the action class but cannot fiure out how to pass this to the servlet. Should I simply call ServletActionContext.setRequest(name of the servlet object). Thanks for your help, I really appreciate any pointers!! -- View this message in context: http://www.nabble.com/linking-struts2-action-to-pre-existing-pure-Java-servlet-tf3899596.html#a11055023 Sent from the Struts - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

[S2] datetimepicker reset value to 00:00 when type="time" after submitting page
I have a datetimepicker in my JSP to let user select time:
When user select 10:15 and submit to webserver, after the web page refreshes
the value becomes 00:00.
Is this another datetimepicker bug?
I have a type converter for converting time the format string is "HH:mm":
public class TimeConverter extends StrutsTypeConverter {
private static Logger log = Logger.getLogger(TimeConverter.class);
public Object convertFromString(Map context, String[] values,
Class toClass) {
log.debug("entering convertFromString() values[0]='" + values[0] +
"'");
if (StringUtil.isEmpty(values[0])) {
return null;
}
try {
Date dt = TimeUtil.getGuiTimeFormat().parse(values[0]);
Object rtn = new java.sql.Time(dt.getTime());
log.debug("rtn=" + rtn);
return rtn;
} catch (Exception e) {
log.error(e, e);
}
return null;
}
public String convertToString(Map context, Object o) {
log.debug("entering convertToString() o=" + o);
String str = null;
if ( o != null ) {
str = TimeUtil.getGuiTimeFormat().format(o);
log.debug("entering convertToString() str=" + str);
}
return str;
}
}
But the debug log shows the time str is 10:15.
Thanks!

Let me rephrase: I don't know how you'd be able to use a Set directly on a web page simply because it's *not* indexable.

Name them whatever the name of them is in the action. For example, I have a JSP page that uses the following S2 tag for a text input field where exMap is (obviously, I guess) a map with its backing object's id as the map key: I dynamically create additional components with the following JavaScript, called from a method taking id, which, and idx parameters: var name = 'exMap[' + id + '].' + which + '[' + idx + '].foo'; var sTag = ''; This example is a little bit different because each of the map entries is an ordered list (and I formatted and edited heavily so it might be minorly broken), but you get the idea. d.

In a merged iterator, know which iterator current item belongs
Hello, I want to successively call several iterators. This works perfectly fine with a merged iterator, but now I need to know to which iterator the currently processed entry belongs to, since they have to be treated differently. See the small example below that illustrates my intention. Currently I just check if the current entry is an odd number or not, but this does not work if numbers.length>operators.length+1 or even operators.length NUMBER OPERATOR Thanks, Anton signature.asc Description: OpenPGP digital signature

Parameter Mapping with Set elements
Hi!, I'm having a problem trying to map elements from a Set Collection in my Action to form components, and to generate form components dinamically and have them inserted in this set. Any suggestions? The main problem is that the only way to access collection elements with ognl is like accessing an array, and when i generate those dinamic components with javascript, i don't know how to name those elements to have them mapped to the Set.

sort entries by the selected tag
Hello, I would like to sort the menu created by the selected tag. So far I just pass a TreeMap where the entries are sorted already.

Or, you can use the s:text tag (assuming you are using struts 2) and:
where format.decimal is defined in a resource bundle somewhere (see
http://cwiki.apache.org/confluence/display/WW/Localization for
details) as:
format.decimal={0,number,###.##}
The text tag reference
(http://cwiki.apache.org/confluence/display/WW/text) has some links to
more information about using MessageFormat.
