Newbie question about Tiles suitability.
Hi, I just got told I have to create a web site similar to myYahoo where the user can customize what they want to view on the screen. You know the type, where you can pick and choose from a number of categories and a page is custom created for you. Is this a job for the Tiles framework? Thanks for any help.

How to use the html:text tag properly.
Hi, I am trying to get the value attribute to work in the text tag. I have an 'ITEM' bean with two properties. One is set up when the user selects an item. When they go to a page I want the page to display the existing value in 'item.primeLocation' and I want the text box to be prefilled with the value from 'item.primeLocation' but have the text user input go into 'newPrimeLocation. Both parameters are within the ITEM bean. I think the value attribute is supposed to get the from the 'primeLocation' but I actually get primeLocation passed into the text box. I must be doing something wrong. TR TDPrimary Location/TD TDbean:write name=ITEM property=item.primeLocation//TD TDhtml:text property=newPrimeLocation value=primeLocation/TD /TR Thanks for any help.

How to fill a String[] property?
Hi,
I have a form with a string array property 'Activities'. The form has the
following methods:
private String[] mActivities = new String[6];
public void setActivities(String[] parm1) { mActivities = parm1; }
public String[] getActivities() { return mActivities; }
On my page I need 6 textboxes to be filled in each representing an element
in the mActivities array. I have tried the following:
tdhtml:text property=item.issue.chargeInfo.activities[0] //td
...
tdhtml:text property=item.issue.chargeInfo.activities[5] //td
but I get bean.populate errors.
Any help is appreciated.

RE: How to track the row id......
Hi, I just finished doing something similar. I have an ArrayList with a bunch of charging objects. When the user goes to the summary screen I iterate through all the objects and show them the data. I have added two icons, edit and delete at the end of each charging row. Each of these icons is a link e.g.: html:link page=/editCharging.do indexed=true When the user clicks on the edit icon my editChargingAction is called with a request parameter of 'indexed'. This holds the element in the ArrayList that the user wants to edit. I take that index, get the details for that charge, put that object into request session and send them back to the same page.

The match attribute in the choice element is a regular expression, which matches against the parameter. In this case, the parameter value you would provide would be the User-Agent header. This would allow view selection to be abstracted out of the Action class. Any view could be updated to get an alternate rendering, without changing the Action code. The caveat being that you'd have to agree on what always provides the match expression in each Action. The User-Agent is a good choice, but other applications might use something else. -- === David M.

Subject: How to use Log4j with a startup logging servlet
I want to use Log4J for logging exceptions thrown in a Struts-based web app.
After searching through this list, I found 2 common solutions:
1. Extend the Struts ActionServlet and override the init() method to set up
a Log4J Category. Then in any custom Action class I can just call
servlet.Category.debug() (let's assume Category is a protected or public
variable).
2. Write a separate startup servlet and again set up LOG4J in the init()
method. But my question is, how do I invoke this servlet from my custom
Action class? Do I need to do a RequestDispatcher.forward() to the servlet
when an exception is thrown? Then how do I get back to the page I am on to
display the error message?

Struts design advice requested please.
Hi, I have been using Struts now for about a year and I really like it. It has saved me a lot of time and made my apps quite stable. I have just been placed on another large struts project. It will be pushing struts to the limit. A quick question on design. What I am going to do is a bit difficult to explain. This app is going to be used by users to input inventory data into two different databases, an AS400 and an Oracle/SQL database. The user will enter essentially the same type of inventory data into each system, but, there are differences between the two. Part of the project plan is that through a config switch, parameter etc, I will be telling struts if we are working with an AS400 system or an Oracle/SQL system and then the guy will slightly change, just the addition or deletion of a gui element. Example of required elements entered by the users in a form. AS400 ORACLE/SQL employeeID employeeID storeroom storeroom locationlocation location type bin Number My question revolves around the form bean. I though about making a form bean that includes all the properties that are required by the Inventory object for the AS400 and the ORACLE/SQL system. This would make one large generic form bean. Then I thought about making an abstract class that includes all the common elements amongst the object and from there I would extend and create an AS400 inventory form or an Oracle/SQL inventory form. If I go this way then how do I set up the Struts.xml file to use the specific inventory form, if it could be one of two? I hope what I am trying to convey is making sense. Depending on a config setting I think I should be using one of two form beans, not known until run time. Any help in setting up the above is appreciated.

RE: Struts design advice requested please.
Thanks a lot I really appreciate all the advice. It really helped me out. One thing you said really surprised me. You said: For ActionForms, my preference is to use larger generic form beans. They are really a throw-away object, and linking them too closely to a hierarchy can be a waste of time. I have been doing the opposite of generic forms. My forms usually consist of objects within object. For example I might have an invoice object that has and employee and a part object within it. It would have been faster for me to make on big flat form but I thought that it would be better to break it up amongst a number of objects. Looking back though, most of my forms all they do is collect data that is used somewhere else. Something for me to think about.

I would consider extending the ActionServlet so that it stores which schema is in use. The Action could then look at the schema setting to route or otherwise handle the request as needed. Ideally, the Action should be able to just pass the schema setting back to the business logic, without knowing anything about the schema itself, except that it is some fact the business layer needs to know. I though about making a form bean that includes all the properties that are required by the Inventory object for the AS400 and the ORACLE/SQL system. This would make one large generic form bean. Then I thought about making an abstract class that includes all the common elements amongst the object and from there I would extend and create an AS400 inventory form or an Oracle/SQL inventory form. This is always a tricky question when dealing with persistence layer issues. Scott Ambler's paper http://www.ambysoft.com/mappingObjects.pdf discusses this in depth. For ActionForms, my preference is to use larger generic form beans. They are really a throw-away object, and linking them too closely to a hierarchy can be a waste of time. The business logic beans that form the real peristence layer are another matter (see Ambler). But ActionForms are really just an expediency. If I go this way then how do I set up the Struts.xml file to use the specific inventory form, if it could be one of two? If you use subclassing, then you would have an ActionMapping for each ActionForm subclass, which may or may not use the same Action class. If you use one big bean, then they can all use the same Action, and it can sort out which fields are being used for the active scheme. In either case, you can use a separate page for each schema1 type, and let the controller route to one or the other, or pass the schema type to the page and let it use the logic tags to render the appropriate form. The latter reduces the number of pages that need to be maintained, but makes for larger pages. The former creates more individual pages, and seems like better MVC to some folk. It's really a six-of-one half-a-dozen of the other issue, and may be best left up to whomever has to maintain the presentation pages. -- Ted Husted, Husted dot Com, Fairport NY USA. -- Building Java web applications with Struts. -- Tel +1 585 737-3463. -- Web http://www.husted.com/struts/ -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

Another questions about checkboxes
Hi, I have a form that has a Boolean property that in the form reset method is reset to false. This form is used over two pages. In the first page there is a checkbox that the user can select to modify this Boolean property. This page is submitted to an action class that just forwards to the second page. In the second page I display the checkbox value. After the second page the form is submitted to another action to process. The problem. In the first page the checkbox works correctly. In the second page, which is a summary page of selections on the first page, the form values are shown correctly. When the second page gets submitted to the last action class, the checkbox is reset to false and that is the value that the action class gets. I know that the second page, even though it only displays the values shown in the first page, is calling the reset method of the form. I need the reset method to set the Boolean to false because the user might go back a page and uncheck the checkbox. Does anyone have any experience of using checkboxes when the form goes over multiple pages? Any ideas on how I can fix this. Thanks a lot of any help.

Hi,
I have an action class that could get called after a users session has
expired. When the action class is called I have the following code:
if(session == null || session.isNew())
{
return mapping.findForward(logon);
}
I have a global forward defined for logon.
Now the problem:
When a user's session is expired and the click a link they go to this
action. The if statement evaluates to true and the forward to logon
correctly occurs. Then the rest of the Action code continues to be
evaluated.
Why is the rest of my code following the above if statement
continuing to be
run when I have done a forward?
Are you absolutely sure about this? No other people on your server who
could generate the same debug code as you? Because I don't expect the
code to continue: the return ...; statement jumps out of the method.

Can't forward to a global?
Hi,
I have an action class that could get called after a users session has
expired. When the action class is called I have the following code:
if(session == null || session.isNew())
{
return mapping.findForward(logon);
}
I have a global forward defined for logon.
Now the problem:
When a user's session is expired and the click a link they go to this
action. The if statement evaluates to true and the forward to logon
correctly occurs. Then the rest of the Action code continues to be
evaluated.
Why is the rest of my code following the above if statement continuing to be
run when I have done a forward?
Any help is appreciated.
Alex

how does this checkbox thing work?
Hi, can't seem to get this checkbox to work. I have an app that reads the fields of a database and creates an array of field objects. Then a jsp is produced allowing the user to input the new data. I have a checkbox that is tied to a field object that has a setValue(String) and getValue() method. When I read the database and the checkbox should be set I set the value to 1. This seems to have worked but when the screen is produced and the checkbox is checked and I uncheck it I find that the setValue() method is not being called and that the old value of 1 is being set.

Help!!Banging my head trying to figure out how to do this.
Help, I can't figure out how to structure this. I am trying to make a dynamic program that updates fields in a table. Essentially the program should work as follows: A user logs in. I get a list of objects that they can modify. For each object I get a list of tables. For each table I populated a vector of Field objects. All this goes into two Maps. The first map is(Object, Tables) the second map is (tableName, tableDefinition) with the tableDefinition object having a vector of fields. Hopefully this is not too confusing at this point. I use an iterate tag to iterate through the nested maps to dynamically create a nav bar of: object 2 | table name table name object 2 | table name table name Now the fun part. I can select a table and iterate through the tables fields and create a debug html table listing field name, field caption, field type, field default value. Now I need to create a form created from these fields. And the form when submitted need to populate the fields default value? First question: How does a form populate a field that is within a ArrayList that is within a map that is within another map? How can I create the input fields at run time? Any help is really appreciated. Thanks Alex -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
getting indexed variable during scripting.
Hi,
I have a logic:indexed loop that has a couple of html elements that use the
indexed property. I need to get the current iteration and use that variable
in a JavaScript statement.
Specifically I have a text box that has a JavaScript calendar that when
selected allows a user to select a date. When the user has selected the date
the JavaScript function needs to know the name of the text box to place the
values.
A code snippet of the resulting source is as follows:
TDinput type=text name=field[6].fieldDefaultValue value=
readonly=readonly/TD
tda href=javascript:show_calendar('addOnForm.a250171_dttm',null, null,
'DD/MON/');
I need to replace the a250171_dttm with the field[6].fieldDefaultValue
dynamically.

Comment on using the Struts platform for this project.
Hi, I have to create a app that allows users to change/input data into a database. Sounds simple. Problem is I have to make it dynamic so that is will work with any database or table. I have a back end VB app that will send me: Field name Field caption Field type Field display type e.g.. radio, drop down, text box etc. I then need to dynamically create a form with form elements. Is Struts suited for this or should I stick with a plain servlet? Alex
How to pass initialise parameters to action class
Hi, I have an action class that has a variable that I want set from the web.xml file. To prevent the action class from reading the xml file everytime it is accessed I wanted to set the variable once in the action classes init() method. After looking at the action class I see that there is no init() method. Any idea how I can set the value of a variable only once in the action class? Regards Alex

How to do this type of validation?
Hi, could someone give me some architecture hints on how to do the following: Lets say you have a business object that has a couple of mandatory and optional fields populated by the user. The user goes from page to page, each time inputting either a required piece of info or an optional piece of info. I need to create a web GUI to allow an administrator to specify which optional fields for their site are mandatory. When the user goes through each page he must populate the mandatory and any optional fields made mandatory. My first idea was to create an xml document that consisted of the business field name and then a true/false flag. The web page would allow the user to set the optional fields as required or not. Then I thought I could feed this document to my business object and set boolean fields to required or not. Then the question is how do I force a user to input a piece of info when they visit a mandatory page? An example of my proposed code is: private int stockNumber; //optional field private boolean bStockNumberRequired=false; //flag to specify if this field is now required public void setStockNumber(int i); public int getStockNumber(); public void isStockNumberRequired(boolean is) public boolean getStockNumberRequired(); Any thoughts are appreciated.

Need Iterator/Indexed help quick, please.
Hi, I have gotten myself into a bit of a jam and I am wondering if someone could help me out. I got a web app that a customer wants to make some last minute changes to. From the looks of it, it looks simple but I can't figure it out. Hopefully someone has an idea on how I can do this. I have a vector, that holds a CategoryList object, that holds a vector of Category Objects. Each one of these objects has the usual set/get methods: CategoryList Object set/get CategoryList Vector add Category List adds a Category to the above Vector getCategory(int i) returns the Category at that element for the above Vector. Category Object set/get categoryGroup (String) set/get categoryValue (String) ***I think this is what I need populated*** set/get categoryValues (Vector) of Strings There can be an unknown number of category objects in the CategoryList Object. On my page I want to create a series of Select dropdowns with the categoryValues of each Category Object. I have managed to do this via: TABLE logic:iterate id=category name=CategoryList property=categoryList scope=session TR TD bean:write name=category property=categoryGroup / /TD TD html:select name=category property=categoryValue indexed=true bean:define id=categoryValue name=category property=categoryValues/ html:options name=categoryValue / /html:select /TD /TR /logic:iterate /TABLE This creates something like: TR TD Project /TD TD select name=category[0].categoryValue option value=CommissioningCommissioning/option option value=Commissioning,Engineering SignoffCommissioning,Engineering Signoff/option option value=Commissioning,Government AgenciesCommissioning,Government Agencies/option option value=Erection/InstallationErection/Installation/option option value=Erection/Installation,StructuralErection/Installation,Structural/o ption option value=Erection/Installation,Structural,Footings Foundation /select /TD /TR My problem is getting the value of what the user selected. All I want to do is for the first select box, whatever the user selected put that in the respective categories categoryValue property. But I do not see where that value is going. When I look at the request parameters I get: category[0].categoryValue = Erection/Installation,Structural,Footings Foundation In a nutshell is there a way to populate my objects with the value that the user has selected? Do I need to modify my object? Any help you can provide is highly appreciated. Alex pwCategory.java pwCategoryList.java
REPOST: A hint how to do the following with a bean.
Hi, Need a hint on how to do the following: I have a bean which is a vector of items. Each item object has a name, description price etc. When the user selects an item I create this vector and pass it to a page which iterates through the vector and creates a table. Something like: name desc price storeroombuyer The table I get has the same data for the first two rows. I want to take out those first two rows and place them into the table caption. Without iterating through the vector how can I get the name and desc property of the first item. That data is going to be the same for all the other items in the vector. Thanks for any help. Alex

newbe: radio button iteration

I want to create a list of radio buttons all with the same name but the values being the entity number. For example: input type=radio name=entityNumber value=123 1996 DODGE DAKOTA PICK-UP TRUCK input type=radio name=entityNumber value=234 1996 DODGE BUS I have tried the following: logic:iterate id=en name=entitySearchList scope=request TR TD CLASS=TD_Border html:radio name=en property=entityNumber value=bean:write name=en property=entityNumber / / /TD TD CLASS=TD_Border bean:write name=en property=entityName / /TD /logic:iterate The above obviously does not work. I would appreciate it if someone could lend me a hand. Thanks Alex
struts architecture question.
Hi,
I am trying to figure out if I have properly designed my classes.
I have a class that extends ActionServlet. The only reason it does that is
because all my web apps need a couple of generic objects in the application
session before anyone can use the applications.
So I overrode the doGet and doPost and init() methods. Examples are below:
public void init() throws javax.servlet.ServletException
{
super.init();
//do Some Configuration;
}
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws java.io.IOException, javax.servlet.ServletException
{
HttpSession session= request.getSession(true);
*/
if(session.getAttribute(Constants.SERVLET_CONFIG)==null)
{
session.setAttribute(Constants.SERVLET_CONFIG, configSettings);
}
/**
* place the rdserver object in the session
*/
if((session.getAttribute(Constants.RDSERVER))==null)
{
rdServer server=new rdServer(strHost, strPort);
session.setAttribute(Constants.RDSERVER,server);
}
super.doGet( request, response);
}
I don't know what is wrong with the above it just looks wrong. And, when I
start this app in tomcat I can see that the web app is being parsed and
loaded twice.
Any design tips, comments on the above are appreciated.
Alex
Can you comment on this design idea?
Hi,
hopefully someone can comment on an idea I have.
I have a VB backend that I talk to via a socket to handle db access. When a
connection is made to the back end I put a Boolean value of TRUE under the
active key in the application session. If for whatever reason the VB
backend goes down I get the key active and set it to FALSE. I created a
tag that as the user goes from page to page it checks this key and if it is
active it continues displaying the page and if it is not it takes the user
to a generic, back end down page.
A problem I found is that a user could be on a page and submit data to a
servlet. If the backend has gone down while the user has been on a page, the
servlet will not know about it and attempt to do some work. I do not want
this to happen. I want a similar set-up that I have for the pages for the
servlet.
I was thinking of overriding the doGet and Post methods of the ActionServlet
to check if the active key is true. If it is continue passing the request
to the servlets if it is not then send them to a generic, back end not
available page.
Something like this:
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws java.io.IOException, javax.servlet.ServletException
{
String errorPage=/serverNotAvailable.jsp;
if(key)
{
//do usual work
}
else
{
RequestDispatcher disp=new request.getRequestDispatcher(errorPage);
disp.forward(request,response);
}
super.doGet(request, response);
any comments are appreciated.

Hi,
I am using the latest cut of Struts from the nightly build. I need the iterate
function.
Something has happened to my error messages. In my action class if a method fails I
set the
following error:
errors.add(ActionErrors.GLOBAL_ERROR, new
ActionError(error.invalidBidAmount));
I then save the error via:
if(!errors.empty())
{
this.saveErrors(request,errors);
return (new ActionForward(mapping.getInput()));
}
When the user is redirect back to the page they came from all the user sees is the
error.header
msg.
I have this tag in my web page after the body tag:
html:errors/
I must be missing something. Could someone set me on the right track.

Hi, I notice that the message tags written by David Winterfeldt have been rolled into the Struts project. I downloaded the latest version of Struts and I am retrofitting the message tags. I think I figured out that I need that following code in my action class to save a message: messages.add(ActionMessages.GLOBAL_MESSAGE, new ActionMessage(rfqRFQCreationResponse.title,Hello)); But now I am wondering how to retrieve the message on a page. I tried: %@ taglib uri=/WEB-INF/struts-validator.tld prefix=validator % validator:messagesExist name=MyMessage ul validator:messages id=message name=MyMessage libean:write name=message//li /validator:messages /ulhr /validator:messagesExist but this is not finding the message in the request session. Could you give me a quick tip and tell me how to access the new version of the messages on the page? Thanks Alex = Regards Alex Colic, HBA, B. Ed PopWare Inc. Driving down the cost of conversions!

A bit of design help please?
Hi, I am wondering how the following can be done in Struts. You have a page with two frames, one being a navigation frame consisting of a series of links that populate the second frame. On start-up the second frame has a log in screen and the navigation frame just has a company image. On successful login you want the navigation pane to have a series of links to tasks that the user can do. They click on a task and the second frame fills with a form etc. When the user logs out or the session is killed the navigation frame links are removed. How can I control and keep the navigation frame synchronised with what is going on? Any help is appreciated. Alex
Re: A bit of design help please?
Hi, Thanks for the reply. Just a bit of elaboration. What I should do is have a simple login page. No problem. On successful login I send them to a framed page. So far so good. Question about this dynamic links. Could you elaborate on how to create them using struts? Alex -- Date: Thu, 16 Aug 2001 09:37:04 -0400 To: [EMAIL PROTECTED] From: Jon Crater [EMAIL PROTECTED] Subject: Re: A bit of design help please? Message-ID: [EMAIL PROTECTED] alex-- i think the best way to do this is not to have the frameset appear until after a successful login. obviously, you don't want the links to your functional areas to appear until after the user has been authenticated. so throw up a non-framed page which contains your login form. after authenticating the user, forward to your frameset, where you can dynamically build navigation links in the navigation frame based on permissions, etc, and where you can prepopulate the content pane with a default page until the user selects a link. targeting the content pane from the link is simple HTML (a href=/SomeAction.do target=contentlink text/a). your forward should then go to the content pane, where your output is displayed. when the session dies or the user logs out, simply forward him/her to the login page or some other non-framed page. hope this helps...
ActionForm not being updated. Please advice.
Hi, I am trying to get that iterate tag to work. I am interating through a vector a displaying the results. I have one field that I want the user to update hence I have made it a text box. When the page displays, the data is correct but when the user enters something into the text box and hits submit, the form in the actionservlet has the old data not what the user has entered. My jsp is as follows: html:form action=viRFQBid.do logic:iterate id=item name=ItemBidForm property=itemList TR TD CLASS=TD_Border bean:write name=item property=number / /TD TD CLASS=TD_Border html:textarea name=item property=partDescription / /TD TD CLASS=TD_Border html:text name=item property=unitPrice indexed=true / /TD /TR /logic:iterate /html:form Anything the user enters in the unit price is ignored, the old value is present in the form. My Struts config is: form-beans type=org.apache.struts.action.ActionFormBean form-bean name=ItemBidForm type=com.popware.rd.viPro.form.ItemBidForm/ /form-beans action-mappings actionpath=/viRFQSummary type=com.popware.rd.viPro.action.viRFQSummaryAction name=ItemBidForm input=/pwRFQList.jsp forward name=successpath=/pwRFQBid.jsp/ /action !-- Process the rfqBid action -- actionpath=/viRFQBid type=com.popware.rd.viPro.action.viRFQBidAction name=ItemBidForm input=/pwRFQList.jsp forward name=successpath=/pwRFQBidResponse.jsp/ /action /action-mappings viRFQSummaryAction works, the form is populated and passed to pwRFQBid.jsp but whatever the user enters as a unit cost is ignored. I take the form out in viRFQBidAction and check it. Any help in figuring this out is appreciated. Alex
How to use the indexed property-Please get me going?
Hi I am trying to use the indexed property with a page. I have a vector that holds a series of item objects. Each item object as a name, desc and unit price field. The page iterates through the vector and creates a table displaying the name and desc of an item and a text field for the unit price. I want the user to input the unit price and then submit the table. I have added indexed=true to the unit price text field: bean:write name=item property=unitPrice indexed=true / I have downloaded the 0912 nightly build. When I get to the page with the above table I get the following error: javax.servlet.ServletException: org.w3c.dom.DOMImplementation: method createDocumentType(Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;)Lo rg/w3c/dom/DocumentType; not found If I take the index=true off I do not get the above error? Could someone please help me out. Alex

Advice on how to implement the following:
Hi, I need a bit of advice on how to implement the following. I am creating a page that holds a list of item names along with their description. So far I created a vector that holds an array of items and then passes it to a Struts page in the request scope. The page then iterates the array and then produces the page. So far no problem. Now I need to add a text field in which the user can input prices for these items. Then I need that form submitted to my actionservlet for processing. This is where I get lost. I thought of adding a price field to my item class and then as the vector is iterated on the page I create a textfield binding it to the price field in the bean. But when the page is submitted I don't think the vector will be passed to my action servlet for parsing. Any help is appreciated Alex
objects still being cached why?
Hi, I am still having that problem with objects being cached. In my jsp I have some data that is displayed regularly. Therefore I have put that object into the context via: context.setAttribute(CommonProblemList ,tbeList ); When the data the list is based upon changes, I have a monitor class that listens for that change and then repopulates a similar object and then puts it into the context via the method/line above. Then in my JSP I access the data via the below: TR TDbean:message key=prompt.select/TD TD logic:present name=CommonProblemList scope=application html:select property=wrTitle bean:define id=list name=CommonProblemList scope=application property=list / html:options collection=list property=name/ /html:select /logic:present TD /TR I have set nocachein my actionservlet via: init-param param-namenocache/param-name param-valuetrue/param-value /init-param My problem is that if I change the data in my database the data in my JSP page is not updated. I have stepped through my code and my monitor class does see the change in the database, it is compiling a new object and it is placing it into the application context. I checked the object data being placed and it does have the new data in it but if I got to the web page which uses that object it only shows the old data. If I shut tomcat down and restart it I do see the new data. Can someone suggest what is going on here and how to fix it? Thanks for the help. Regards Alex Alex Colic.vcf
best way to create front end to web.xml
Hi, I need to create a GUI front end to the web.xml file. This way the file can be configured from a web page. What I thought about doing was to create an admin screen, have the user log in, and check against a file etc. Then I was going to get the servletContext, open a stream and read the web.xml file. Then populate a vector and pass it to a struts page that would set up a series of labels and textboxes with prefilled info. Once the user has submitted the page I was going to read through the parameters and update the file. Sound good? Regards Alex Alex Colic.vcf

why is servlet.init method being called twice.
Hi, I created a base actionservlet class that in its init method, the first thing it does is call super.init(). In this base class I set up common settings for all my web apps.

The problem is that as my webapps start the init methods in all three classes are being called twice? Is this correct? Alex Alex Colic.vcf
help with checkbox
Hi, I am hoping someone can point me in the right direction. First, I have a checkbox that regardless of if the user checks it or not I need it to be set to true. Can someone suggest a way via JavaScript or otherwise to set this checkbox to true. Second, for the same checkbox, if I do not set its value and then go a few pages forward I have a status page that displays the value of the checkbox. If I have not checked the box the value is false, if I then go back a few pages and then check the box and go to forward to the status page again it is shown as checked but, if I go back and uncheck the box and then go forward it is still shown as checked. Any ideas what is up. Thanks Alex

Re: how to forward page on logic:notPresent?
Hi, I thought about login:forward but from what I know I would have to know the name of the next page and place that in this tag. I don't want to do that because if I change the order of my pages in the struts.xml file then I have to remember to change this tag. I think what I am looking for is a way to either, immediately submit this page if an object in the session does not exist and this let the action servlet figure out what the next page should be or, check in the previous page if this object exists and if does not then bypass this page.

why is this form not being properly submitted?
Hi,
I have a form with two buttons. If the user clicks one button the form is
submitted via the standard action defined in the form tag. If it is the
second button, I change the action and submit the form. The problem is that
I have a text box on the form that when I check its value in the action
servlet that parameter is not being passed. A snipped of my html page is as
follows:
html:form method=POST action=wrSearch
TABLE name=tblModifyWRCriteria
TR
TD
bean:message key=prompt.wrNumber /
/TD
TD
INPUT TYPE=text ID=wrNumber Name=wrNumber SIZE=20
/TD
TD
On the default button wrNumber is submitted to the action servlet but on the
the second button I do the following:
function doWRModify(wrNumber)
{
workrequest.wrNumber.value=wrNumber;
workrequest.action=/wrModify.do;
workrequest.submit();
}
I set the value of the text box, then I reset the action then I submit the
form. In the below case I get null returned:
String strWRNumber=request.getParameter(wrNumber);

Need help with logic:iterate :)
Hi, I am trying to get a handle on the logic:iterate tag. I have an object in application scope under the key 'storeroomList.' There is a vector of objects under the property 'storeroomList'. Each one of the objects in this vector has a property 'name.' What I am trying to do is go through the vector and print out the names. I have attempted the below but the only storeroom name to be printed out to the screen is the last storeroom. I traced the execution of the iterate class and it looks to be getting the correct data, going through each element of the vector and pulling out the name property and then looping through all the elements without printing them to the screen and then the bean:write is called. Any help is as usual greatly appreciated. Oh, bonus question.. Lets say I only wanted to print out a particular storeroom. Iterate through the vector but only print the storeroom that had the name "main." logic:iterate id="storerooms" name="storeroomList" scope="application" property="storeroomList"/ bean:write name="storerooms" property="name" /BR /logic:iterate Regards Alex

Any idea why? my web.xml file is as follows: !-- Action Servlet Configuration -- servlet servlet-nameaction/servlet-name servlet-classcom.myCompany.rd.pwActionServlet/servlet-class init-param param-nameapplication/param-name param-valuecom.myCompany.rd.reqPro.ApplicationResources/param-value /init-param init-param param-nameconfig/param-name param-value/WEB-INF/struts-config.xml/param-value /init-param init-param param-namedebug/param-name param-value2/param-value /init-param init-param param-namedetail/param-name param-value2/param-value /init-param init-param param-namevalidate/param-name param-valuetrue/param-value /init-param load-on-startup2/load-on-startup /servlet Regards Alex
Update on caching lists.
Hi so far my list caching is going well,
I have set up a thread to monitor database changes and to update the lists
stored in the servlet context. Unfortunately, although my program is
noticing the change in the database and it is recompiling the data and
putting the new data into the context under the same name, the lists are not
being updated.
I place lists in the servletcontext via:
context.setAttribute("storeroomList",storerooms );
When the lists change I recall my cachelist method and the above line is
repeated. I thought that would replace the present list with the new one but
that is not occurring.
Is there another way I am supposed to be replacing attributes?
To test I opened up a web page populated with my list and then went to the
database and changed some values in the list. My program then caught these
changes, and repopulated the lists and then placed them in the context
again. I then opened up another window and the page was populated with the
old data.
Any help in this matter is appreciated.

Update on caching lists.
Oh, I thought about using removeAttribute() and then setting the attribute of the list again but I am worried about pulling a list out of the servletcontext just as a person might be accessing a page that needs that list. Regards Alex
how to cache lists?
Hi, Lets say you have a web app that runs over a number of web pages in a wizard fashion. On each one of these pages you need to present the user with a select box holding lists. e.g. locations, cities, etc. This data is read from a database and rarely changes. How would you cache these lists so that as each user access this site they do not need to have this info downloaded again? I was thinking in the init() of my ActionServlet to access the database and get these lists then place them in the session with Application scope. I think this would allow each user to access the data without reaccessing the database. Any comments or suggestions are appreciated. Regards Alex
