RE: Retrieve Data From WebServer
Hi, I was also having similar problem some time back. According to my knowledge... If the data is common to all the users then may be you can have a singleton class and then only once you can populate the data, and every time you use the same data. If the data is user specific then I think storing in the session is must. Lets wait about the others ideas also...

Re: Antwort: Re: Creating new Session without invalidating the old one [*]
[EMAIL PROTECTED] wrote: Hello! Thank you to all for your hints. Now, I want to tell you, what I did at last. My application consists of nearly 100% forms. The application is logically devided into two parts (-> represented by two browser windows), and it must be possible to get from one part to the other. If somebody goes to the other part, datas must be migrated from the first one, which needn't to be closed - it's possible, that the user works with both parts at the same time. To achieve these needs, I created an object in the ServletContext, where datas are stored, which are needed to migrate from one session to another session. The key to these data in this object is the session ID. If an user switches to another part of the application, this is done using a direct call to a jsp, like href=some.jsp;sessionid=E19593A3AB3BB4EBB92C6E64916B729C I'm using sessionid (and not jsessionid), because this way, the request is sessionless (I'm using URL-rewriting for session-tracking and https) and I can check in the loginfilter myself, if the request belongs to an already logged in user. If the sessionid is valid, the user gets a new one and I can fetch data from the ServletContext-object. My thinking was to put 2 objects in a single session, each representing a respective window's attribute. 1 session, 2 "windows". You could just have this new Window class extend HashMap to get key-value pairs. -Dave - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

It has the advantage of not throwing a checked exception and its parameter ordering makes more sense to some (myself included). A reason to not specify a value for html:text, at the view level, is that it overwrites the value in an associated form-bean object. This could lead to overwriting user input or overwriting data that was populated from an Action. It may be acceptable to specify value on a checkbox, for instance, because user's don't typically interact with this value directly. Still, if a value for a checkbox, like any other form control, was set in a controller class, then a page level value will overwrite data. At the very least, this is counterintuitive.

Re: validator and DynaValidatorActionForm
Thanks a lot for all your input and help. It looks like I need some basic concepts clarified. Here a very short background of the application and what my intension is: The object 'subscriber' is a special business object: it represents the logged in user and contains a lot of information about him: Personal data like name, address, e-mail, preferred language etc. But it contains also information about his roles, type of subsciption he bought etc. Shortly I need parts of this information almost everywhere in the application and thats why the thing sits in session scope. The action we were discussing 'changePersonalDataForm' represents a form where the user can change some of this informations such as personal data, language etc. Other things such as roles, subscibtion information etc are not visible to the user. The object has logic to retrieve its information from various database tables and also store information back if there are changes. This is performed exclusively in this object not in any action. The object is created and filled when the user has successfully logged in. So I used to initially fill the firstname directly from the business object into the form. If the user submits the form the information is updated in the object and also written back to the DB server. Nice things like ChangeEventListeners as available in Swing and also in JSF are sort of missing in Struts (at least I did not find something alike) So the key question seems to be: What is the correct or preferred way to link business-objects with form beans. Is this only possible by copying data from a business object to a form bean or is there any 'smarter' way? Copying ends up in writing a lot of copy-code which is inefficient. I am looking for sort of a component model, which means I have a couple of objects in session or even application scope and can directly use then in many different forms/actions. But so far I am missing a concept like SWING controls do have it where you can bind controls such as a listbox, textbox etc directly to objects or even database tables. I think JSF offers similar things but I don't see anything alike in struts 1.2.8 (the version I am currently using). Maybe someone could clarify these things for me or you may have some good recipes for me, how to solve these things best with Struts. Many thanks again for your help!

Basically, you need 2 actions, one to populate the form and one to

Or at least two action mappings, if you want to use automatic
validation. If you're happy to invoke validation manually, you can get
by with just one action and one mapping.

Nope, with that approach you would simply *seperate* your one action
class into two classes which each encapsulate one branch or your if
statement below -- i.e. an action that does 'Populate the form' and one
that does 'Perform update operation'.
If you don't like having two separate classes, there are various options
for combining them, including the various flavours of dispatch action
and the approach you illustrate below.
In my Action class I did:
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
{
ActionForward af = null;
..
String operation = request.getParameter("operation");
.
if (operation != null &&
operation.compareToIgnoreCase("update") == 0)
{
. Perform update operation here
}
else // showData
{
Populate form here
}
return (new ActionForward("/showPersonalData.do"));
}
The surprising thing (at least for me...) is, that when running in the
debugger, execute method is NEVER called (does not stop at any
breakpoint) !!!
Do you have validate="true" on your action mapping? If validate is set
to true, the framework will perform validation for you automatically
before invoking the action. Hence, you need to either a) have two action
mappings in your config (note: two mappings, not necessarily two action
classes), one with validate=false and operation set to null and one with
validate=true and operation set to whatever; or b) using a single action
mapping, set validate=false and call validate() manually as appropriate.
Is there no more intelligent way then creating lots of actions?? Maybe
this is a motivation to move to JSF!!

Extending tag libraries
This is a little OT, but it, uh, kind of has to do with Struts :). I'm interested in adding a few attributes to some of the struts tags. They're really only useful in the context of a specific web project I'm working on, so I'd really prefer not to edit the Struts TLD and implementation (for various other reasons too :). Problem is, a lot of these have to do with view/layout, so I wanted to use .tag files. Everything's fine if I extend a single property, say : <%@ attribute name="property" required="true" type="java.lang.String" %> Problem is, there are a lot more attributes, most are optional, and different permutations, etc. Is there a relatively easy way of doing this in .tag files? Do I have to use tag classes and, if so, is it possible to tell the JSP processor to re-compile the stuff I output so it doesn't write verbatim to the client? - Scott - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I don't think you need 'value' here: The 'name' attribute [1] is "The attribute name of the bean whose properties are consulted when rendering the current value of this input field." Does this work? Even after dealing with the 'first display' problem, that still leaves you validating the form bean (which may be missing data) yet displaying values from some other bean sitting in session scope.

Re: Best way to secure struts-webapps?
Thomas Hamacher wrote: Laurie, thanks for the input. I am aware of the container managed security. But as far as I read in the internet, there is no good solution to use container managed security together with tiles. So if I wanna have a login-box on every page, that redirects dynamically to the same page after login I will have some trouble with the container managed solution. Is this not true or did I misunderstood anything? It all depends on exactly what you need to achieve. CMS uses URL matching, so you'd probably have to have some way to have two distinct URL mappings for each page, one secured and one not, and have the login box forward to the secured page -- e.g. if you're on /foo.do, have the login box forward/redirect to /secure/foo.do. I haven't tried any of this though, so I'm just guessing at a possible solution. And another question to the filter-based solution as Leon also recommended: Does this also work if I have different tiles for one page and some of them are secured and some aren´t? E.g. I have a tile for an adminMenu, which is only loaded if I have a user with admin-roles in the session, but which is part of a usual public tiles-page? This way the servlet-filter will never find it´s pattern, will it? Is there a simple -Tag combined with an entry "role" in the action mapping and role-security-check in the RequestProcessor enough security to be sure, only admins access these actions? Or is there a way to get around these security-checks, which I should keep in mind? Generating different content based on the current user role is really orthogonal to how you establish user credentials -- that's access control as opposed to authentication. Once you have the user authenticated, be it via CMS, a filter or something else, you can then employ various techniques (including, but not limited to, Antonio's Dimensions project) to control the visibility of content.

RE: validator and DynaValidatorActionForm
Why are you making these fields so complex? You have Instead of the simple form: ? Why do you need to specify all of that redundant information like value and name when you have the property attribute? And why are you pulling values from the session scope instead of the request data that was submitted? That seems an unusual choice to my thinking. Also, what is your html:form action specified there? Is it listed as "/changePersonalDataForm"? Or another form name? Using a different form might be your problem - after all the html:form uses the bean associated with that form so a different bean would have different values, especially if you are mixing and matching values from a session scoped bean with a request that has its own values.

Re: Dynamically Initializing Checkbox Value
Yes you do, the form is passed in as one of the parameters to execute(). The typical pattern is for the action to be invoked via an action mapping, populate the form bean and forward to the JSP. It's during this action processing that you copy your business data into the form bean, thus initializing it. The form in the JSP is then bound to the form bean, both reading from and writing to the same place. When the form is submitted, another action is invoked and in that action you copy the appropriate data from the form to wherever you need it to complete the operation. To answer your earlier question, you *can* have a form which takes its values from a bean other than the form bean -- I think you've already had that working for some input types. However, in the case of checkboxes, that's going to be problematic, since the input's value is doing double duty -- it's specifying the value that should be submitted *if* the checkbox is selected, and also specifying the value that the checkbox property must have for it to be considered selected already. If you don't want to copy the permission data from your model into the form bean before rendering the form, you can do as previously suggested and put the entire business object into the form bean; that solution actually doesn't prevent the properties being written/updated. There are problems with this approach for certain types of inputs, but for boolean values rendered as checkboxes it should work fine. L. Anthony N.

Re: Dynamically Initializing Checkbox Value
Anthony,
I am puzzled by your comment that you don't have a form bean before you
get to the jsp. We do this all the time. Say I want to display a list
of inventory items for a user. I retrieve a list of inventory items
matching the query data the user gave me and create an array of
inventory item forms to pass to the jsp. I convert information from the
list inventory item beans and place each one into the array. Then just
set the array as a parameter in request scope and then use that
parameter to build my jsp.
I do the same if I am providing a means for a user to update information
on an item. I initialize the form in the prep action, display the jsp
and read the form in the processing action. So I read/write to the same
inventory item form bean and read/write to my DAO inventory item bean
for the backend. The only reason I use 2 different beans is it was
mandated to separate the view from the model and I need to convert some
data say the unit of issue ID to a actual unit of issue for the user.
I hope this helps.

Hello all,
public class Role {
private int id;
private String name;
private String description;

}
Each of those properties has getter and setter
methods. By the way, in the *actual* Role class,
the
permission booleans are named such things as
"canAccessProjects" and "canEditCustomers" and
other
such actual permissions, which is why I am not
using
an array of booleans in this case. I want to
refer to
them by name.
Now I wanted to create a JSP that contained a
form,
that allowed a user to edit a role. Here is the
definition of my form bean (called EditRoleForm):
public class EditRoleForm extends ActionForm {
private boolean roleId;
private boolean roleName;
private boolean roleDescription;
private boolean rolePermissionA;
private boolean rolePermissionB;
...
private boolean rolePermissionN;
}
I kinda dont understand why do you need 2 beans as
long as u only care about
reading from them.
you could have somehting like this in your form
bean
public class EditRoleForm extends ActionForm {
Role role = new Role();
/*getter method*/
}
and then in your jsp you have
Permission A:
you dont need to specify a value explicitly, it
loads the field with
whatever value the property has.
In this instance, the form bean looks quite similar
to
the role bean.
In my JSP, I have the following:
Name:
Description:
property="roleDescription"
value="${role.description}"
/>
Permission A:
property="rolePermissionA"
value="true" />
Permission B:
property="rolePermissionB"
value="true" />
...
Permission N:
property="rolePermissionN"
value="true" />
As you can see, all of the checkboxes are going to
be
initialized blank. I would instead prefer them to
be
initialized with the value in the role within the
request scope. I was able to do this using the
"value" parameter in the text and textarea tags,
but
the value parameter is used differently for the
checkbox tag.
I hope this clears it up.
One final note: After reading everyone's
responses,
and also reading around on the web, I seem to be
getting an idea that the name of the property in
the
Role bean and the Form bean should be identical,
and
this is the way it is able to initialize the value
in
the checkbox, and also set the correct value in
the
form bean when it is submitted. This seems like a
bad
idea. For one, how do we know that there is a
one-to-one mapping of beans to form beans? If I'm
modifying a few beans all on the same JSP page, I
certainly don't want there to be confusion.
I hope I've made myself clear, and I look forward
to
everyone's response. I really appreciate the time
and
effort everyone has taken in helping me out thus
far.

Re: Session Timeout
I think I found the offending code. It is located in the Struts
RequestProcessor.processLocale method (which is called *before* the
pre-process). In that method is the following code:
// Has a Locale already been selected?
HttpSession session = request.getSession();
So I will *always* get a non-null session when I get control in the
processPreprocess method.
There doesn't seem to be a hook before any processing is done.

A new session is created when you request a new session somewhere,
it's not created automatically. However, there could be a filter,
request processor, action, or JSP somewhere that does a
request.getSession() or .getSession(true) (or '... session="true"...'

If Facelets was supported in a standalone environment (i.e. without JSF) you could possibly just invoke a *.xhtml URL and skip the intermediate step altogether. It would be nice if we could make Tiles work this way.

Here is what I mean : My webapp requires some filesystem path to work

requires to customize the container JVM ("-Dxxx=yyy"). Is there a

Re: Session Timeout
[moving to struts-user list]
A new session is created when you request a new session somewhere,
it's not created automatically. However, there could be a filter,
request processor, action, or JSP somewhere that does a
request.getSession() or .getSession(true) (or '... session="true"...'
in JSP), which all will create a session if none exists. If it's
buried deep enough in a chain of filters it could *appear* to be magic
:-)
There is a method isNew() on the session that you can check to see if
it's a new session that might help in your case.

Subject: Session Timeout
Hey Everyone,
I am trying to use a custom session timeout JSP. To do this, I extended
"RequestProcessor" and overrode "processPreprocess" and added the following
code:
HttpSession sess = req.getSession(false);
if(sess == null){
// even when the session IS timed out, I never get here.
String uri = "/myapp/sessiontimeout.jsp";
try{
doForward(uri, req, resp);
}catch(Exception ex){}
return false;
}
The problem is, even when I know the session was expired, I never get a null
session. Am I missing something?
Thanks
John

Re: Dynamically Initializing Checkbox Value
Actually, that's incorrect. I want to *read* from the
Role bean. I want to *write* to the form bean. I
just don't know how to go about it yet. :) It seems
like I have to read/write to the same form bean, which
doesn't make sense, because I don't have the form bean
until I get to the JSP page, so there's no way to
initialize it.
Thanks for the help,

Hello all,
public class Role {
private int id;
private String name;
private String description;
private boolean permissionA;
private boolean permissionB;
...
private boolean permissionN;
}
Each of those properties has getter and setter
methods. By the way, in the *actual* Role class, the
permission booleans are named such things as
"canAccessProjects" and "canEditCustomers" and other
such actual permissions, which is why I am not using
an array of booleans in this case. I want to refer to
them by name.
Now I wanted to create a JSP that contained a form,
that allowed a user to edit a role. Here is the
definition of my form bean (called EditRoleForm):
public class EditRoleForm extends ActionForm {
private boolean roleId;
private boolean roleName;
private boolean roleDescription;
private boolean rolePermissionA;
private boolean rolePermissionB;
...
private boolean rolePermissionN;
}
I kinda dont understand why do you need 2 beans as long as u only care about
reading from them.
you could have somehting like this in your form bean
public class EditRoleForm extends ActionForm {
Role role = new Role();
/*getter method*/
}
and then in your jsp you have
Permission A:
you dont need to specify a value explicitly, it loads the field with
whatever value the property has.
In this instance, the form bean looks quite similar to
the role bean.
In my JSP, I have the following:
Name:
Description:
Permission A:
Permission B:
...
Permission N:
As you can see, all of the checkboxes are going to be
initialized blank. I would instead prefer them to be
initialized with the value in the role within the
request scope. I was able to do this using the
"value" parameter in the text and textarea tags, but
the value parameter is used differently for the
checkbox tag.
I hope this clears it up.
One final note: After reading everyone's responses,
and also reading around on the web, I seem to be
getting an idea that the name of the property in the
Role bean and the Form bean should be identical, and
this is the way it is able to initialize the value in
the checkbox, and also set the correct value in the
form bean when it is submitted. This seems like a bad
idea. For one, how do we know that there is a
one-to-one mapping of beans to form beans? If I'm
modifying a few beans all on the same JSP page, I
certainly don't want there to be confusion.
I hope I've made myself clear, and I look forward to
everyone's response. I really appreciate the time and
effort everyone has taken in helping me out thus far.

Re: Best way to secure struts-webapps?
Laurie, thanks for the input. I am aware of the container managed security. But as far as I read in the internet, there is no good solution to use container managed security together with tiles. So if I wanna have a login-box on every page, that redirects dynamically to the same page after login I will have some trouble with the container managed solution. Is this not true or did I misunderstood anything? And another question to the filter-based solution as Leon also recommended: Does this also work if I have different tiles for one page and some of them are secured and some aren´t? E.g. I have a tile for an adminMenu, which is only loaded if I have a user with admin-roles in the session, but which is part of a usual public tiles-page? This way the servlet-filter will never find it´s pattern, will it? Is there a simple -Tag combined with an entry "role" in the action mapping and role-security-check in the RequestProcessor enough security to be sure, only admins access these actions? Or is there a way to get around these security-checks, which I should keep in mind? Thank you very much Thomas Am Dienstag, 29.

Best practice for external webapp configuration ?
Hello,
I'm searching for best practice in JEE applications to put configuration
elements outside the war/ear.
Here is what I mean : My webapp requires some filesystem path to work
(logs dir, system-dependent config files...). I'm using a java sytem
property to setup a root path for external configuration, but this
requires to customize the container JVM ("-Dxxx=yyy"). Is there a better
"JEE" way to do such things ?
Nico.
