Struts and Quartz
Hi all, working with a struts application that I am trying to add quartz to but I am running into a slight snag. I can't seem to get the scheduler to be recognized. I am trying to follow the following tutorial: http://www.onjava.com/pub/a/onjava/2006/03/01/job-scheduling-in-web-application.html Unfortunately I am running into errors at the point of setting up the servletcontext. I am trying to use their sample code, as I don't know what it would be otherwise. thanks in advance for any help or suggestions on this matter. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Indexed Properties with nested Tags
Alright, I guess I should have thought that. I was worried that my fundamental understanding for this was wrong. For debugging I am putting my information into a String which is not being iterated (it for some reason always works, but those that are iterated over don't for some reason. I have no problem prepopulating, and no problem showing the form again, it's only when I try to have what the user inputs get placed into the form that is where I am lost. thanks once again for all the help everyone, sorry if I sound like a broken record.

Re: Indexed Properties with nested Tags
I should also like to say that the one part that seems to be giving me the
most problem is the setting of the variables in action when it is
submitted.
The other thing I am curious about is if what I am doing is incorrect. I am
using one action for both the submit as well as the prepopulate based on a
url parameter.
thanks once again.

As it stands I have come up with the following :

All I want to be able to do is pull 3 things out of an object, display

Indexed Property and Hand Cranking Lazy List
Hello all, I am sorry to subject this list to yet another person who doesn't
understand something, but I can't for the life of me figure out hand
cranking lazy lists.
I am using 1.2.9 with java 1.5.0_06 And I can't get lazy lists to work.
I am trying to use what I found at :
http://wiki.apache.org/struts/StrutsCatalogLazyList
And as such have :
In the ProdSelectionFrom:
private List skills = new ArrayList();
public List getSkills() {
return skills;
}
// non-bean version so as not to confuse struts.
public void populateSkills(List skills) {
this.skills.addAll(skills);
}
public void setSkills(Product skill) {
this.skills.add(skill);
}
public Product getSkills(int index) {
// automatically grow List size
while (index >= skills.size()) {
skills.add(new Product());
}
return (Product)skills.get(index);
}
In the JSP:
And can't even get this to display properly.
I am getting the error message:
No getter method for property: "skills" of bean: "ProdSelectionForm"
javax.servlet.ServletException: javax.servlet.jsp.JspException: No
getter method for property: "skills" of bean: "ProdSelectionForm"
Could someone please point me in the right direction as I am at my wits end
on this.
The entire point of what I am trying to do is to be able to post a list of
information about a product (such as description, number, price etc) and
allow the user to edit the number and have them submit the form so that I
can update a database with a new order.
I am using a product Object which has all of the characteristics mentioned
before as well as others, and each of them have publically available getter
and setter methods.
I would also like to confirm that the comment I read that I should be using
strictly strings when dealing with the jsp is correct - can someone confirm
that ?
Also is there a problem using ArrayList over List ?
Thanks so much for any thoughts/ time you can give me.

I think I have found the problem - or at least a potential cause. Would it
be correct in stating that this will not work using ActionForm (what I was
using) and that I must instead use DynaActionForm ?

Indexed Properties
This has been driving me nuts for the past little bit.
I have a page that is populated using indexed properties. The prepopulation
works fine, and I get the results as I would expect them, but trying to
submit the form I get an index out of bounds exception. I know that it is
being caused because the page doesn't have the arrayList to use in the
indexed properties. I guess my question boils down to using indexed
properties properly. I will start by putting in an explanation of what I
have and what I am trying to do:
The following is what I am working with :
JSP:
What I am trying to achieve is that a user clicks on a link, they are sent
to page, and all of the values are prepopulated. The page is then displayed
and the user has the option to modify any of the variables that they want to
before resubmitting the page. (When they resubmit the form has a url
parameter attached to it). What is happening (or at least what I believe is
happening is the following: link is clicked, reset is called action sets
the variables, page is displayed, user can modify the page and resubmit,
reset is called on the form, the action is called (this is where it dies as
there is no longer an ArrayList) to modify. My question is am I going about
this in a manner that seems sensible or am I way off base ? I have the
values being prepopulated, but when trying to use the values that the user
puts in I can't use them in the action, nor can I pull the values from the
form without again setting the values in the form. I am hoping it is that
I have over looked something, but it's possible that I don't understand
something as well.
Here is the Action code (This is the entire execute method) :
HttpSession session = request.getSession();
ProdSelectionForm prodSelection = (ProdSelectionForm) form;
User user ;
user = (User)session.getAttribute("User");
Order order = new Order();
ArrayList products = new ArrayList();
ArrayList pageRes = new ArrayList();
ArrayList results = new ArrayList();
String action = (request.getParameter("Dest") == null ? "populate" :
request.getParameter("Dest") );
order = user.getCurrOrder(user);
if(action.equals("populate"))
{
prodSelection.setResults(order.getProducts());
}
if(action.equals("Delete"))
{
ArrayList p = new ArrayList();
p = prodSelection.getResults();
int count = 0;
while (count < p.size())
{
Product t = (Product) p.get(count);
t.setDescription("" +t.getNumProducts() +">" +pageRes.size()
+"<");
p.set(count, t);
count++;
}
t.setDescription("" +t.getNumProducts() +">" +p.size() +"<");
p.set(0, t);
user.setOrder(p , user);
prodSelection.setResults(p);
prodSelection.setTest(prodSelection.getTest()+" + " + p.size());
return mapping.findForward("success");
}
return mapping.findForward("success");
Form code: (In the form code is an ArrayList called results. This arraylist
contains a bunch of Product )
public Product getResultsPage(int index)
{
if(this.results == null)
{
this.results = new ArrayList();
}
while(index >= this.results.size())
{
this.results.add(new Product());
}
return (Product) results.get(index);
}
public void setResultsPage(int index, Product p)
{
if(this.results == null)
{
this.results = new ArrayList();
}
while(index >= this.results.size())
{
this.results.add(new Product());
}
results.set(index, p);
//return (Product) results.get(index);
}
public void setResults(ArrayList results)
{
this.results=results;
}
public ArrayList getResults()
{
return this.results;
}
Products is an object that stores various things about a product with
numProducts, and description being two of those things.
Within Products is both getter and setter methods for the numProducts as
well as description.
Thanks so much for any help you may be able to provide.
Re: setting an an html:text value with another html:text
That will work I suppose I was just hoping that there was a somewhat more elegant way of doing it, the fact that I'm not using JSTL should have hit me in the face that this wouldn't be elegant however. thanks for the thought.

Hi all , I am attempting to do the following, and it obviously isn't working, but I was hoping someone on the list would point me to something that might work instead: I have this text field and I want to be able to alternate the readonly property from true and false. I tried to put in the below which is bolded " Any thoughts or ideas as to how I could do that in a nice manner would be greatly appreciated. What is going to happen is that the action is going to toggle the value depending on a parameter comming in from the URL. thanks in advance for any thoughts or ideas.
Re: Using html:errors with a field that is iterated.
On 11/3/06, robin bajaj <[EMAIL PROTECTED]> wrote: Hi Adam, Yes, I think html:errors is a pretty good validaiton mechanism. Especially if you use the Struts validation framework (validation.xml, validator-rules.xml) for generating your errors. Yes I am using validation.xml and validator-rules.xml. For showing errors right beside each specific field that fails the validation, you will need to have tag beside each field. For this question I was more curious about those fields that are being generated by using an iterator, which means there may be many fields with the same validation needs, but I won't know how many fields there are. Basically I am wondering if there is a manner to use error validation to preform validation on a list that may have from zero to hundreds of elements. The list that I am using is being created by : Hopefully that question makes sense. But if you want to show all the errors at once (say above all the fields) then you can use tag as-is.

Using html:errors with a field that is iterated.
Hi all I am using struts 1.2.9 and starting to work on error validation. So far I have my login page using: etc etc etc. I was wondering firstly Is this still the best manner in which to display errors ? The second question which has more to do with the title is How does one use error validation on fields that are iterated ? As an example if I have 3 fields where a team has to enter a score, I want to ensure that the only values that are entered beside each field is a number. If any of those fields have other than a number I want the error to appear only beside that particular field. Is this something that can be done with error validation ? I am looking around for examples but most examples are quite dated and I am trying to use the best things available to me. thanks in advance. Adam
Re: Textfield problem with pulling value out.
I managed to get the problem working, unfortunately that fix is by doing
something that is against best practices (if I understand them correctly).
To get this to work what I ended up doing was pulling the results from the
search and putting that in the reset of the resultsAction. I am pretty
certain your question about the setting the value on the set and not the get
hit the nail on the head. I will work on the suggestions that you made and
see what progress I can make.
Thanks again so much for all the time and effort.

It's more likely that I don't understand. This is my first struts project

Here is all of the getters/setters that I have so far. It is quite possible

for numProducts indexed property. And i dont understand why are you
populating blank values in the getter methods..I mean you should be doing
that in your setter methods..something like
public void setNumProducts(int index,String val) {
while(index <= results.size()) {
results.add(new Product());
}
Product p = (Product)results.get(index);
p.setNumProducts(val);
}
maybe i dont understnad the context of your problem properly, but this
what
i do with indexed properties.

Re: Textfield problem with pulling value out.
One other thing I just realized that I should include is the fact that all
of my forms are request based, which doesn't allow me to include the form
information from one to the next, so to get around that (for more testing) I
have included the array in a Session variable so that I can pull it out in
the second action.
Again thanks for all thoughts/ideas/suggestions

Re: Textfield problem with pulling value out.
If this is a bad technique I would be more than happy to change it to a more
standard technique. Any suggestions on how to improve my code are always
welcome.
thanks for the suggestions thus far.

I don't think I've ever seen that technique before, but you have to
remember
that size() is 1 based and index (or get(index) ) is 0 based. So when
someone calls getNumProducts(5), your while loop fills in indexes 0, 1, 2,
3, and 4 (because then index and this.results.size() are both 5), then you
proceed to ask for results.get(5), which doesn't exist. You should be
able
to change your while list to something like:
while(index >= this.results.size() + 1) {
this.results.add(new Product());
}

Re: Textfield problem with pulling value out.
Here are the 2 get methods that I have.
thanks again for all the help.
public int getNumProducts() {
return numProducts;
}
public int getNumProducts(int index)
{
if(this.results== null)
{
this.results = new ArrayList();
}
while(index >= this.results.size())
{
this.results.add(new Product());
}
Product p = (Product) results.get(index);
return p.getNumProducts();
}

post the getter method for the numProducts. that might be causing the

Textfield problem with pulling value out.
Hi all I have been working on this probelm for the past couple of days, and
don't seem to be making any progress on it. I am fairly certain it is a
problem with my understanding of struts, and as such it makes it quite
difficult for me to solve the problem myself.
I am trying to use a textfield and pull values from it. The following
explains the scenario. User clicks on a page, page loads with a form that
has a textfield. User enters search criteria and submits form. This works
fine. Page returns with the search form and textfield, as well as a second
form that displays the results of the search. This also works fine. The
user then goes through the results filling in numbers for each result
indicating how many of each they would like to order and then submit the
form. This is where the problem results. I end up gettting an error from
the page anytime I submit the form where there is 1 or more results.
Submitting with no results works fine and the page loads correctly.
Submitting with 1 result errors out with
java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
Submitting with 10 results errors out with:
java.lang.IndexOutOfBoundsException: Index: 2, Size: 0
Submitting with 100 results errors with :
java.lang.IndexOutOfBoundsException: Index: 6, Size: 0
Submitting with 200 results errors with :
java.lang.IndexOutOfBoundsException: Index: 155, Size: 0
The number seems to be random (I am guessing it is how far into the
form it gets before the error is encountered)
Any help on this would be much appreciated.
I am including all the information that I believe to be important but
would have no problem including more.
In the jsp form there is:
Search
Add To Order
Product
Product Desc
Quantity
NO RESULTS
In the action (this action is only for the search results):
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws
Exception
{
SkuSearchForm skuform = (SkuSearchForm) form;
HttpSession session = request.getSession();
User user = new User();
Order order = new Order();
ArrayList products = new ArrayList();
ArrayList results = new ArrayList();
user = (User)session.getAttribute("User");
order = user.getOrder(user.getCurrOrder());
products = order.getProducts();
int number = 0;
int count = 0;
Iterator iter = results.iterator();
//there is nothing happening in here as there is no results for some reason.
while(iter.hasNext())
{
Product p = (Product) iter.next();
if(p.getNumProducts() != 0 )
{
products.add(p);
}
count++;
}
{
count = 1;
Product p = new Product("TestProd " + count,
"TestDesc"+count + "
" +count, 10, new BigDecimal("101.0"));
products.add(p);
results.add(p);
count++;
}
order.setProducts(products);
order.setOrderId("ID12");
user.changeOrder(order, "ID12");
skuform.setResults(results);
return mapping.findForward("success");
}
In the form (The methods I thought were appropriate):
public void setResults(ArrayList results)
{
this.results=results;
}
public ArrayList getResults()
{
return this.results;
}
public Product getResult(int index)
{
if(this.results == null)
{
Struts textfield +Iterated list +retrieving user changed value from form.
I am working with struts 1.2.9 and trying to use the iterate function. I
seem to be having a problem extracting the value from a text field inside an
iterated loop. I am able to get/set values thare are being placed simply
into html, but run into difficulties when working with the text fields. I
am able to set the values into the text field, but unable to pull them out
when in the action code of the form. The following is what I have used for
code thus far:
If I understand the struts wiki page that I was pointed to properly the name
in the text must be the same as the id, but when I would try that I would
simply receive index out of bounds errors - that was making all references
to counter called results.
Results is an object that is holding a product, description, and
numProducts.
This is in the Action portion - well it is a snippet of the entire thing.
ProdSelectionForm prodSelection = (ProdSelectionForm) form;
int count = 0;
// take in the number of items in the order ArrayList and iterate through
them
while(count < order.getProductsSize() )
{
Product p = null;
// pull the product from the order at each position to manipulate them.
p = (Product) products.get(count);
// set the order amount to be what the old amount was on top of the
amount that is currently on the screen
p.setNumProducts(p.getNumProducts() + 1 + prodSelection.getNumProducts
());
// the below code was to test and see if the variable would change at
all, with the +100 it would increment the amount on the screen by 100
everytime the action was called, so that lead me to believe that I am
setting the values right.
//p.getNumProducts() + 100 + prodSelection.getNumProducts() );
// set the product back into the product arraylist so it can be passed
to the
products.set(count, p);
count++;
}
//set the product arrayList back into order so it can be presented on the
screen.
order.setProducts(products);
And finally for the form I have the following relevant code:
/**
* @return Returns the numProduct.
*/
public int getNumProducts() {
return numProducts;
}
/**
* @return ReturnsnumProduct at the specified index
*/
public int getNumProducts(int index) {
Product p = (Product) results.get(index);
return p.getNumProducts();
}
/**
* @param numProducts The numProduct to set.
*/
public void setNumProducts(int numProducts) {
this.numProducts = numProducts;
}
I seem to be able to pull the value from the page, but it won't pull the
changed values - that is to say it will only pull the value that was there
when the page was first presented regardless of anything that I type.
Could someone point me to where I am having a brain fart. Ps. I have been
made aware that I should be using JSTL, but would welcome any other critisms
the list might have to offer.
thanks in advance for your time on this matter.
