[solved]RE: Nested error
I never did figure out how to fix the exception I was getting, but I found
an alternate implementation that works. However, my business logic is built
on ArrayList and I didn't want to change that. Thanks to the magic of
getters and setters, I was able to do both:
-
Form snippet:
private ArrayList items;
public Object getItems(int index) { return items.get(index); }
public Object[] getItems() { return items.toArray(); }
public void setItems(int index, Object item) { items.set(index, item); }
public void setItems(Object[] items) { }
public ArrayList getItemlist() { return items; }
public void setItemlist(ArrayList items) { this.items = items; }
-
I noticed that setItems() is never called so I never bothered to implement
it. Everything is now working fine.
Thanks for your time.

Does BeanUtils.copyProperties do a shallow or deep copy? Also, it is copying

Subject: Re: Nested error
It was initialized when JSP was prepared, then response was returned
to the browser. If you use formbean with request scope, it is gone.
When you hit the submit button, you initiate new request, it which the
form is recreated, and this field may not be initialized.
So, the fact that you were able to render a page means nothing, if you
use request scope for formbean. Use session scope or reinitialize
formbean each time. Caution: if you use request scope, then reset()
may be not called (not sure on that), so initialize the form in the
consructor.

RE: Themes
Use CSS. Use one JSP/tile to get your content together, then based on the company setting, choose a CSS style sheet to go with it. The style sheet would contain your graphics, fonts, layouts, etc. Take a look at http://www.csszengarden.com/ to see the possibilities of this approach. Wiebe -Original Message- From: Martin Ravell [mailto:[EMAIL PROTECTED] Sent: Monday, June 13, 2005 5:22 PM To: Struts User Mailing List Subject: Themes I have a requirement to build a 'Themes' (think 'skins') capability into the UI of my Struts app and would just like to poll the list for ideas on the best way to approach such a mechanism. Multiple customers use the same app but they need to be presented with a view that meets their specific requirements. For example graphics, fonts and even layout would be specific to the user's login (actually their company/organization which is stored in the database). Now, for ease of use I guess something relying on CSS would be a way to go. Since I already use stylesheets for most HTML elements specifying a particular theme's stylesheet would not be hard. The tricky part is that I'd also like to be able to specify different jsp pages (mainly for Tiles layouts) in case I need to modify the layout beyond what is easy to do with CSS. Ultimately I may well have functionality in the app itself that is specific to a given customer so this concept should deal with handling customisation to that level well. Ideally I'd like to have a concept of an 'alternate source' directory that is used by the app to load it's jsp. i.e. the app first looks under the appropriate alternate directory for a jsp and uses the page it finds there if it exists but falls back to the standard jsp dir if there is no alternate. This would mean that I could create a theme with only those pages that need to be modified rather than copying and modifying the entire jsp source tree. If anyone has had to implement something along these lines I'd love to hear from you. What sort of mechanisms have you found work well within the structure of a Struts app? My architecture is Struts, Tiles, Spring and Hibernate if you are interested but I'm thinking that it's the Struts area that I'll be looking at mostly for this job.

RE: PlugIn and the base URL
Hey David, that is a great idea. Let me build on it a bit... When the .war file is deployed, the baseURL property will be blank. When the application starts up, it will check this property. If the property is blank, the app will be in 'inactive' state and the only menu item presented to the user is 'Activate'. The action for 'Activate' will read the URL from the response and set the property. The application is now in the 'active' state and operating normally. The next time the application starts up and checks the property, it is not blank so the app is 'active'. The activate action could do a couple of other things as well, such as record the activation time (if you need it for billing) or fire off a message to a licensing or billing server (for hosted apps, etc).

The startup information you would obtain, in that situation, on the host and server port would be wrong. Only the request object would have the correct data. With that in mind, the Devil's Advocate suggests: Can you provide a plug-in to check a file for the information you require? On first run, there would be no data so let them, upon first installation, run an action. That action could see if said file exists and, if not, put it's url information (from the request) into that file (and this one time into that class's class instance data).

RE: [Very OT] Hypothetical challege
The simple answer is to store all your session data in a database, with a cookie value as the key. When the client connects, get the cookie value, read the session data from the database, do your stuff, update the database, and respond to the user. This will create a permanent session, which will survive shutting down the browser, web server, app server, and whatever else. The session will only end when the user explicitly logs out and terminates the session. If you don't like the performance hit of going to the database every time, then add a plugin. When the application starts, the plugin will read all the sessions from the database into memory. When the application ends, the plugin would write out all the sessions to the database.

A few facts and requirements: 1) Suppose you have 2 machines. One must serve as your web server and the other must serve as your EJB server. 2) Suppose you must keep track of some sort of session data for each client. How you store the session data is flexible to a point... You want to take advantage of stateful sessions for whatever reason (maybe your EJB server has more resources or something like that). 3) You obviously have a remote reference to your stateful session EJBObject in your web tier. 4) For whatever reason, you anticipate that you will want to restart your web server now and then while there will be some moderate traffic to it going on. Yet, you don't want to make all the clients lose their state. 5) You can use a cookie if you want to remember which client was which when the server restarts. 6) You have the option of storing the remote references to you stateful session EJBObject by getting EJBObject.getHandle() and storing it on the web server machine in a serialized form. 7) No, you can not buy another web server and cluster them! Let's say there is no more money left. How do you catch server/web app shutdown event with no non-portable code, so you can go through all your sessions and save the remote references to your stateful beans on the EJB tier on hard disk so when the server starts back up you would be able to restart the entire app without making the clients lose their state? Yes, this way of a contrived situation, but I am just very interested in how this could be accomplished. Anyone?

Hello Jack,
you detect a session expiration using the getSession( false ) method. If
you use false, the session is not created if there is no current
session.
In fact, in a previous e-mail that I sent, there was my Filter which
used the getSession method.
All it works if the session expires, and you have to set in some way the
web container in order to delete the session object.
So, I don't understand what do you mean I am not looking to create a
timeout but to detect a session expiration, so that the user can be
redirected to a page.

RE: Multibox deselection problem
This is a problem with HTTP: when all the checkboxes are deselected, the
browser doesn't send anything back, so you get the default of what you
started with. To solve this problem you must ensure that at least one box is
always selected.
I solved this problem by creating an additional checkbox that is hidden,
read-only and selected. This will ensure that the browser sends something
back.
String[] defaultEntities = {A, B, C, D, filler};

Subject: Multibox deselection problem
Hi !
I have a problem with the Multibox behaviour. I have checked the online doc
but nothing helped me so far... Here is my problem :
My app workflow is :
prepareImportAction.do - Import.jsp - processImportAction.do
In the prepareImportAction.do, I initialize the entities var (of type
String[], in session scope), so that the checkboxes are checked by default
when the jsp page is displayed :
String[] defaultEntities = {A, B, C, D};
myform.set(entities, defaultEntities);
In the jsp page, I have a set of :
html:multibox property=entities value=A/
html:multibox property=entities value=B/
html:multibox property=entities value=C/
html:multibox property=entities value=D/
I also have a small javascript that allows the user to select or deselect
all checkboxes in one click :
function checkAll(field)
{ var i;
for (i=0;ifield.length;i++)
{ field[i].checked=true; }
}
(nearly the same for de-selecting all checkboxes)
Now here is my problem. When I de-select all the checkboxes in my jsp page,
by hand or by javascript, my processImport.do receives a String[] array
containing the entities that were defined in preparaImport.do as default,
instead of an empty array.
This only happens only when all entities are deselected : if a single one is
selected, I get the desired behaviour.
May you help me to understand where I am wrong and why it doesn't work
please?

What database and version are you using? Paging can be accomplished in different ways in different databases. In some cases you can use a cursor. Other times you can't.

Ooohhh, Let's start a rumor. Craig is going over to Microsoft... It must be true 'cause I heard it on the list. -Original Message- From: Joe Germuska [mailto:[EMAIL PROTECTED] Sent: Tuesday, November 09, 2004 3:41 PM To: Struts Users Mailing List Subject: Re: A new paradigm of Struts development Sorry for going on so long. Nonsense. That's why we have *discussion* lists. I may have misunderstood, and I am at a disadvantage because I am still trying to get a good idea of what JSF is all about, but I thought that Craig saw any merger between Struts and JSF as a temporary thing which was fundamentally not a long run arrangement. Hm. Maybe; I don't recall that. The nice thing about the Apache license is that the code will live as long as you want it to. So the arrangement is as 'long-run' as the community interested in supporting it. Even if Apache revoked Struts' charter and Craig went to go work for Microsoft, the code would still be there, under a license which empowers you to take it and do whatever you need to with it. I don't understand your idea of a view controller, Joe. The view controller is a controller which is not something different from the Struts controller is it? The controller, from my perspective needs to be decoupled from the view. A view controller is just another way of saying, if I understand, that the view and the controller will be coupled. Only as much as the model and the controller are coupled right now. It's more of a logical partitioning of control responsibilities into inbound and outbound. Some things which need to happen before control is passed to the view are common based on the destination view, not the request path. At my job, the ability to hook some kind of control logic to the view has proven a nice way to organize things so that page preparation and form-prefilling behavior is shared and separate from form/request processing behavior. For a lot of things, the split isn't so straightforward, but we've come to like the basic model. Ultimately, of course, there has to be some interface between the view and the controller. I would wish there were an interface that could adapt the Struts architecture with the JSF sort of view intricacies. However, I don't see that the event-based, page-based, JSF approach can do that. And here's where I'm waiting to either have more time to really understand it -- I've read all the intro to JSF articles, but haven't spent time coding with it -- or for someone to make more specific arguments that say I need to do this, and here's why JSF makes it hard or impossible. Or even just here's a way that I can do this, which I need to do, without all that JSF silliness -- isn't this good enough, and less complicated?

RE: Need Ideas for This Puzzle
Keeping the unused fields around as hidden fields is a good idea. It will
keep your 'select all' javascript from getting complicated.
Just make sure that your action doesn't process any of the fields that were
made hidden, because hackers could modify those hidden fields manually
before sending back the response.

RE: sending/maintaning a download link
If you don't have access to a database, then creating some kind of in-memory database and storing it in the servlet context is a good alternative. Use a Struts plugin for setup and cleanup of whatever you use. One thing you will have to be careful of is using up all your memory.

If you've not had any problems, that is good. Tomcat is probably taking care

RE: site shutdown best practice?
Here is what I have done to implement the Site Shutdown use case. Create an application level status variable, called runStatus, with a default value of 'started'. Create a page where the application admin user can initiate the shutdown process. Enter the number X of minutes before shutdown. RunStatus is set to 'shutting down'. A timer is started which will run the shutdown process in X minutes (whatever the admin entered as a value). New Sessions: When RunStatus != 'started', all login attempts are automatically redirected to an information page. Current Sessions: If RunStatus = 'started', do normal action. If RunStatus = 'shutting down', display a 'System shutting down in X minutes' message before doing the normal action. If RunStatus = 'stopped', send user to information page and kill session. Shutdown Process: After X minutes, set RunStatus = 'stopped'. Then do whatever needs doing, like closing database connection pool, notifying admin user, etc. Wiebe de Jong -Original Message- From: Dean A.

Authorization and authentication are done using a database. From time to time, the site needs to be shutdown for general maintenance, upgrades, etc. I want to give the users fair warning that the site will be shut down at such and such a time. I also want to prevent the users from performing operations during this shutdown. I think it would be good if there were still a home page up, with indications that the system is offline and should be back by a certain time. At first I thought I would create some table in my database to control some of this but I think this is not such a great idea, as the reason for taking the site down may be to do something radical to the database.

RE: [OT] DAO ... where to draw the line?
When it comes to app architecture, I always recommend the Core J2EE Patterns
book. The Second Edition is now available and you can get an overview of it
at http://corej2eepatterns.com/Patterns2ndEd/BusinessObject.htm
In response to your question:
A DAO should only contain the SQL code for the
create/read/update/delete/find methods of one single database file or view.
The Business Object, which is new in the Second Edition, wraps the DAO and
manages the state and business rules for that one object. Remove any
business rules, etc currently in your DAO and move them to the associated
Business Object when refactoring.
The Application Service, which is also new in the Second Edition, manages
business rules across multiple objects (Business Objects and/or DAOs).
Remove any business rules, etc currently in your Session Façades and move
them to the Application Service when refactoring.
Leave the transaction control, database connection stuff, etc in the Session
Façade.
So, go with your first example. Employee and Department should each have
their own DAO. If Department is just a simple lookup table, you could
combine them at the Business Object level. If Department is complicated with
its own set of business rules, then make use of an Application Service.

Subject: [OT] DAO ... where to draw the line?
[OFF TOPIC]
I know this is a struts forum, but as struts developers using DAOs,
where do your DAO implementation draw the line?
For example:
Let''s say I have three tables:
Employee (contains employee_id, employee_name, and dept_id)
Department (contains dept_id, dept_name, loc_id)
Location (contains loc_id, location_name)
How deep do your classes go to replicate the data?
Do you do this...
public class Employee {
private int id;
private String name;
private int deptId; // just the id
// .. implementation details
}
or do you do this
public class Employee {
private int id;
private String name;
private Department dept; // all of the data
// .. implementation details
}
and so on and so on. Class Department has the same type of problem.
Does it hold just the id for location or a variable class Location?
Should DAOs just fill in the id (keys) so it is up to the application
using the DAOs to get the Employee class, then the Department class, and
the the Location class like:
Employee emp = EmployeDAO.getEmployee(1);
Department dept = DepartmentDAO.getDepartment(emp.getDeptId());
Location loc = LocationDAO.getLocation(dept.getLocId());
System.out.println(emp.getEmpName() + works in + loc.getLocationName());
or
Employee emp = EmployeDAO.getEmployee(1);
System.out.println(emp.getEmpName() + works in +
emp.getDept().getLoc().getLocationName());
Now this is just a simple example, but where do you draw the line? It's
possible to go on and on and on and cycle back to employee...
Any thoughts, links, tips, best practices, whatvere would be helpful!
Thanks!

RE: Struts security/validation
I had a similar problem, which I discovered when one of my users tried to
enter a street address containing an apostrophe. Since I use apostrophes to
delineate my text strings in my SQL statements, this caused a database
error. I fixed it by not allowing apostrophes to be entered into any of the
test fields.
I admit this is overly restrictive, but I don't know how to get the
apostrophe into my database otherwise. How would you do it Craig?
For SQL destined test, I disallow \ and '.
For XML destined text, I disallow , , , \, and .

Hello all,
I'm in the process of trying to secure my struts application against
Cross site scripting, SQL injection style attacks.
One of the things I'm doing to prevent this is trying to restrict special
characters (;.(){}...etc) getting beyond the validator.
Just thinking out loud for a moment ...
Cross site scripting attacks don't happen when sensitive characters
are inside an *input* field. The problem comes if you *output* the
data without filtering for them. That's why the Struts bean:write
tag, for example, filters , , , and ; for you unless you
explicitly tell it not to, so if you are diligent about how you copy
your database data to output pages, you can safely accept these kinds
of character in input.
I notice that Kishore Senji (one of the other respondents in this
thread) is using Google's Gmail, just as I am at the moment. Since
this is a web application, it's a good thing that Googe isn't
disallowing the magic characters on input into a textarea, or else we
would not be able to participate in this conversation :-).
Is filtering input really the appropriate strategy for dealing with
this problem? If successful it will certainly help, but the approach
strikes me as overly restrictive for most application needs.

RE: Struts security/validation
Craig, both you and Jim suggested that I make use of prepared statements. I implemented my SQL using strings because it is easier to tweak during the development phase. Now that the project is in maintenance, moving to prepared statements is a good idea. Probably help a bit in performance as well. As for the XML/SOAP calls, using the serializer to create the character entities would be good.

RE: Buffering the ouput of a JSP page within an action
Check out Matt Raible's solution to templated-email using Velocity. It is good and I intend to use it for this purpose. http://www.theserverside.com/blogs/showblog.tss?id=SpringVelocityEmail Wiebe -Original Message- From: Amine Bousta [mailto:[EMAIL PROTECTED] Sent: Monday, April 19, 2004 3:01 AM To: 'Struts Users Mailing List' Subject: Buffering the ouput of a JSP page within an action Hello, I'm trying to write a struts action that could save in a database and send by e-mail the output of a JSP page. This JSP page needs attributes values that are stored in the session context. In other words, I need ServletContext of the struts action and the JSP page to be the same. I first tried to use the Java URL object to perform this action but it creates a separate ServletContext. I didn't find any solution to this issue on the internet. Does anybody can help me?...

If you use the strut from an old car, it might have some carbon on it.

The story behind the letter below is that there is this nutball who digs things out of his back yard and sends the stuff he finds to the Smithsonian Institute, labelling them with scientific names, insisting that they are actual archaeological finds. This guy really exists and does this in his spare time! This is the actual response from the Smithsonian Institution. It is a masterful piece of diplomacy. Bear this in mind next time you are trying to let someone down gently. Smithsonian Institute 207 Pennsylvania Avenue Washington, DC 20078 Dear Sir: Thank you for your latest submission to the Institute, labelled 93211-D, layer seven, next to the clothesline post...Hominid skull. We have given this specimen a careful and detailed examination, and regret to inform you that we disagree with your theory that it represents conclusive proof of the presence of Early Man in Charleston County two million years ago. Rather, it appears that what you have found is the head of a Barbie doll, of the variety one of our staff, who has small children, believes to be Malibu Barbie. It is evident that you have given a great deal of thought to the analysis of this specimen, and you may be quite certain that those of us who are familiar with your prior work in the field were loathe to come to contradiction with your findings. However, we do feel that there are a number of physical attributes of the specimen which might have tipped you off to its modern origin: 1. The material is moulded plastic. Ancient hominid remains are typically fossilised bone. 2. The cranial capacity of the specimen is approximately 9 cubic centimetres, well below the threshold of even the earliest identified proto-homonids. 3. The dentition pattern evident on the skull is more consistent with the common domesticated dog than it is with the ravenous man-eating Pliocene Clams you speculate roamed the wetlands during that time. This latter finding is certainly one of the most intriguing hypotheses you have submitted in your history with this institution, but the evidence seems to weigh rather heavily against it. Without going into too much detail, let us say that: A. The specimen looks like the head of a Barbie doll that a dog has chewed on. B. Clams don't have teeth. It is with feelings tinged with melancholy that we must deny your request to have the specimen carbon dated. This is partially due to the heavy load our lab must bear in its normal operation, and partly due to carbon dating's notorious inaccuracy in fossils of recent geologic record. To the best of our knowledge, no Barbie dolls were produced prior to 1956 AD, and carbon dating is likely to produce wildly inaccurate results. Sadly, we must also deny your request that we approach the National Science Foundation Phylogeny Department with the concept of assigning your specimen the scientific name Australopithecus spiff-arino. Speaking personally, I, for one, fought tenaciously for the acceptance of your proposed taxonomy, but was ultimately voted down because the species name you selected was hyphenated, and didn't really sound like it might be Latin. However, we gladly accept your generous donation of this fascinating specimen to the museum. While it is undoubtedly not a Hominid fossil, it is, nonetheless, yet another riveting example of the great body of work you seem to accumulate here so effortlessly. You should know that our Director has reserved a special shelf in his own office for the display of the specimens you have previously submitted to the Institution, and the entire staff speculates daily on what you will happen upon next in your digs at the site you have discovered in your back yard. We eagerly anticipate your trip to our nation's capital that you proposed in your last letter, and several of us are pressing the Director to pay for it. We are particularly interested in hearing you expand on your theories surrounding the trans-positating fillifitation of ferrous ions in a
