RE: Wht does load-on-startup tag in web.xml means ??
Hi Shakti, load-on-startup means you want call your servlet class at the time of server startup. A typical use will be for loading context/application level parameters in the memory. The value indicates the order in which servlets are loaded. For eg:- 1 indicates this servlet will be loaded first. Also, You want action servlet to be loaded before calling your personal servlet.

Hi All, I have a typical problem. I have iPlanet and Weblogic installed. iPlanet is forwarding request to weblogic. 1) From iPlanet server I make a call :- 172.31.235.253 - - [26/Nov/2003:11:26:56 +0900] GET /shvn/dfw/INTEAPP/directDerivatives/BankAdminAuditLog.do HTTP/1.1 200 14149 This call is forwarded to weblogic and I get the page loaded. 2) I have a Run button on the page:- When I click on Run this is the URL generated in iPlanet server logs (same thing seen in the URL):- 172.31.235.253 - - [26/Nov/2003:11:28:19 +0900] POST /shvn/dfw/INTEAPP/directDerivatives/BankAdminAuditLog.do;jsessionid=1EP150JOqJYdAj8YI80z9tx1CgaD3fJtN8oD15pW92rJbPKWIngI!490032195!-1407194149!8080!7002 HTTP/1.1 404 1317 jsessionid was attached in the URL and this results in 404.

Please help. Thanks Very much in Advance. Tapan - Do you Yahoo!? Free Pop-Up Blocker - Get it now
Null pointer in PropertyUtils - set method not getting called in form-bean
I have a colletion(ArrayList) : TenureMatrix which contains beans.
This I am initializing in the action class on first call and setting it in
the request scope.
This is my code for displaying the data -- I am using struts-layout taglib
for this.
layout:collection name=TenureMatrix
layout:collectionInput title=trader.tenor property=spTenureYear
formProperty=spTenureYear /
layout:collectionInput title=trader.tenor
property=spTenureMonth formProperty=spTenureMonth /
layout:collectionInput title=trader.tenor property=spTenureDays
formProperty=spTenureDays /
layout:collectionInput title=trader.tenor property=maxSpread
formProperty=maxSpread /
layout:collectionInput title=trader.tenor property=minSpread
formProperty=minSpread/
/layout:collection
The data is displayed properly on the first call to action.
Here is the generated Html code:-
trth class=ARRAYTenor/thth class=ARRAYTenor/thth
class=ARRAYTenor/th
th class=ARRAYTenor/thth class=ARRAYTenor/th/trtr
td class=ARRAYinput type=text name=spTenureYear[0]
class=ERROR value=5/td
td class=ARRAYinput type=text name=spTenureMonth[0]
class=ERROR value=4/td
td class=ARRAYinput type=text name=spTenureDays[0]
class=ERROR value=4/td
td class=ARRAYinput type=text name=maxSpread[0]
class=ERROR value=44.454/td
td class=ARRAYinput type=text name=minSpread[0]
class=ERROR value=4.454/td
/trtr
td class=ARRAYinput type=text name=spTenureYear[1]
class=ERROR value=6/td
td class=ARRAYinput type=text name=spTenureMonth[1]
class=ERROR value=3/td
td class=ARRAYinput type=text name=spTenureDays[1]
class=ERROR value=7/td
td class=ARRAYinput type=text name=maxSpread[1]
class=ERROR value=66.454/td
td class=ARRAYinput type=text name=minSpread[1]
class=ERROR value=6.454/td
/tr/table/td/tr/table
The setters/getters exist in the form bean properly.
eg:- Variable declarations in form bean:-
String[] spTenureYear=null;
// Get Sets :-
public String[] getSpTenureYear()
{
return this.spTenureYear;
}
public void setSpTenureYear(String[] spTenureYear)
{
System.out.println(spTenureYear+spTenureYear);
for (int i=0; ispTenureYear.length; i++ )
{
System.out.println( ~~~+spTenureYear[i] );
}
this.spTenureYear=spTenureYear;
}
However when I click on submit ( Calls the same action again ), I get a null
pointer in propertyutils!! what might be wrong?
In fact, even the System.out in the *setSpTenureYear* call is not getting
executed !!!
Help..

How to prevent access to pdf files
Hi all, I am on a page. There are a list of pdf files on the page. If a user clicks on a pdf file, I want him to be redirected to a login page if he is not logged in. However this doesnt seem to be happening even with filters. Does the click on a pdf file not recognized as a request? Please suggest, although the question is slightly offtopic.

[RESEND] : Error coming in AppLogin tag - CheckLogin.java - Sample mail application
Hi friends,
I am working on struts -1.1 rc and tomcat 4.0.6.
I have installed mail registration application and it is working fine.
I can see all the pages properly.
However if I open a new browser window and type the URL direcly :-
http://localhost:8080/myExample/mainMenu.jsp
I get a null pointer. Ideally it should send me to the login page.

RE: Country select pull down.
That is very well explained robert. Mick - however if you can avoid using countries from your own database and ejb, use country taglib.That is a very clean way of using countries. Search for that. Tapan In case you want to use countries jsut in On Thu, 2003-03-20 at 20:16, Robert Taylor wrote: snipis this solution you mention something I can put in my DB, and use the dataSource to access directly like you mentioned?/snip No. First. I'm assuming your servlet container is 2.3 compliant and the country list does not change. If this is so, then you would want to implement a ServletContextListener. In the contextInitialized() you would get a reference to your EJB which is responsible for accessing the country list from the data source. Your EJB would retrieve the data in the form of a Collection of LabelValue beans. You would then place the Collection of LabelValue beans in the ServletContext under an attribute name; say countryOptions. At this point, the country list is available to your entire application under the countryOptions attribute name. If your country list must change based on the locale, then you would want to populate your country list in an Action which is invoked prior to displaying the page. In the Action you would basically go through the same process as defined above except you would store the list in the HttpServletSession as an attribute named countryOptions (if it didn't already exist). This way, it available to all requests from the specified locale. If the country list must change based on the locale and it is used on multiple pages, you could abstract the getCountryOptions() into a base Action or you could set up a filter which looks for the country list and populates it if it does not exist. There are probably other ways of accomplishing your objective as well, but the above were off the top of my head. robert If so, how, or where would I look to go in the right direction? -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Thursday, March 20, 2003 9:14 AM To: [EMAIL PROTECTED] Subject: RE: Country select pull down.

Mick, Populate a collection of LabelValue beans with your countries (assuming your have something like countryId, countryName for each country) when your web app initializes (ServletContextListener-if 2.3) and place it in the ServletContext. Then on your .jsp page use the following syntax assuming your country list has an ServletContext attribute name of countryOptions. html:select property=country html:optionsCollection name=countryOptions label=countryName value=countryId /html:select This will reduce the number of custom tags by 277 which should do the trick.
