redirecting to fully qualified hostname
All, The application I am working on is secured with a login that required a username and password. Once a user is logged in, all pages can be accessed as long as there is a Subject object in the Session. My problem is that part of the webapp provided links to pages that open in another window, and when the link is clicked, it is forwarding to the logon page as if the Subject object is no longer in the Session. I've determined that this behavior is only present when the hostname used for the request is not fully qualified upon the intial logon. For instance. User logons on by going to http://serverName/webapp/logon.do Then the application provides a link to http://serverName.mycompany.com/webapp/something.do which open a page in a new window. When the user click the link, a new window is opened but they are forwarded to the logon page as if they never logged on in the first place. How can I have all requests to the original hostname http://serverName/webapp be redirected to http://serverName.mycompany.com/webapp ? Is there anybody out there that has experienced this or knows of a better way to work around this issue? Thanks in Advance, Jonathan

No, the reset method will automatically be called on a Session scoped ActionForm upon each request.

RE: Login Security
You could put a cookie on the user's machine that expires after a certain period of time. Of course this only works when cookies are turned one and an experienced user could always manually remove their cookie. Another solution maybe is to get the user's IP address from the request Header and add it to a list of invalid IP address with their times of entry. Then upon a new request, you will have to check the list and determine how long ago the IP address was added.

[OT] - Login Application
Howdy All, I am writing a custom login application. Our organization has several web applications (Struts of course!) one of which is a shopping cart. The current login application adds two cookies to the users browser - one that stores a number representing a price index and the other an id. (Meaning different users pay different amounts for products depending on their level of membership). The issue: I am adding a 30 day persistence feature to the login if the user selects a check box at login time. It is possible that a users price index will change within a 30 day period due to advancement in their membership. Should the shopping cart (or any other app that needs to calculate price) be responsible for getting the price index vs. the login getting it? Has anyone had a similar situation and if so, how did you solve it?

Subclassing ActionServlet
All,
I need to check the Session for an authenticated user before most requests.
To do this I subclassed ActionServlet and only call super(request, response)
upon verification that authenticated user is in the Session.
if (request.getRequestURI().endsWith(welcome.do) |
request.getRequestURI().endsWith(logon.do) |
request.getRequestURI().endsWith(html))
{
super.process(request, response);
}
else if (request.getSession().getAttribute(USER) == null)
{
//Forward to login page
response.sendRedirect(/welcome.do);
}
I also know about the ability to subclass the RequestProcessor and
providing my own implementation of the processPreprocess method to
accomplish the same thing.
Does anybody know of any serious disadvantages or side effects of
subclassing the ActionServlet class rather than the RequestProcessor class.

Error Handling without using errorPage directive
Hello all,
I'd like to handle any and all exceptions handled thrown by my JSP pages
declaratively, ideally using global-exceptions in struts-config.
Currently, I have a JSP page called by a tile that uses the JSTL Tag
Library. Using the c tag I perform a check like this:
c:if test=${!empty featuredProductView.title}
... do some work ...
/c:if
If the method getTitle() throws an exception, I currently see the
following on the screen:
-- snip --
javax.servlet.ServletException: javax.servlet.jsp.JspException: An error
occurred while evaluating custom action attribute test with value
${!empty featuredProductView.title}: An error occurred while getting
property title from an instance of class
com.mandaladesigns.apps.commerce.framework.view.FeaturedProductView
(com.mandaladesigns.common.exceptions.MandalaException)
-- snip --
This also appears in the tomcat localhost log along with the stack
trace. But what's really interesting to me is the data I placed in
com.mandaladesigns.common.exceptions.MandalaException, which is my own
exception type that subclasses RuntimeException. Though explicitly
using an errorPage directive in the page works, I'd like to avoid having
to place an errorPage directive in all of my JSP files.
So, is there a way that I can place a directive, either in web.xml or
struts-config.xml that will handle these exceptions? It seems that
using error-page in web.xml and global-exception in
struts-config.xml directives are not consulted for this situation. I've
created entries for every type of exception that seems relevant in both
places but they don't seem to be getting called.
Thanks for your help,
Jonathan.

[ANN] FreeMarker 2.3pre13 available
Greetings, I'm making this announcement because I consider that it is of general interest to Struts users who are investigating other view technologies (i.e. alternatives to JSP). A new preview release of FreeMarker 2.3 is available. Though it's a preview, at this point, FM 2.3 is really approaching its final state. FreeMarker is a well known template engine written in 100% pure Java. It is used as a component in various web application frameworks, such as JPublish, Niggle, Open for Business, and Tammi. Also, FreeMarker can be configured for use as the view layer for model 2 web frameworks, of which Struts is the best known example. Here is a link to the manual page that explains how to configure FreeMarker for use in conjunction with Struts: http://freemarker.org/docs/pgui_misc_servlet.html With the 2.3 release cycle, FreeMarker continues to get better. FreeMarker 2.2 introduced clean support for JSP taglibs. One user raved that he was amazed that it was actually simpler and more straightforward to use JSP taglibs from FreeMarker templates than from JSP's! What this means, of course, is that Struts users can migrate from JSP-FM without losing any investment they may have in JSP taglibs (their own or from third parties.) In FreeMarker 2.3, the new visit and recurse directives may well make it easier to do recursive XSLT-style transformations in FreeMarker than with XSLT itself! FM 2.3 also adds some other appealing new features, such as the ability to use variable interpolations in string literals, and the ability to define functions with return values in the template language. In short, for those of you who are open to making your lives simpler by finding more usable alternatives to better-known (and more widely-hyped) technologies such as JSP and XSLT, FreeMarker really deserves some serious attention.

RE: Formatting form data inside the *view* (JSP's)
Hi Sasha,
An alternative approach would be to create a generic mechanism to
populate the ActionForm with properly formatted string values. The idea
here is to write a method that transfers values from a bean to an
ActionForm, automatically applying default type conversion and
formatting based on the bean's property types. Another method can be
added to provide a way to override the default formatting behavior.
I write about this subject extensively in my book Jakarta Pitfalls
(Wiley). Chapter 2, ActionForms, begins with this problem and its
solution. Later sections in the same chapter show how to extend the
mechanism to automatically validate inbound request values (without the
need for declarative specification), and then populate the JavaBean
with converted values using the inverse of the formatting scheme.
The value of this approach is that you don't have to encode the
formatting logic in your JSPs at all. All the formatting code is in one
place, and new JSPs automatically get the formatting behavior without
adding any new code. It helps ensure consistency too, especially if you
have a lot of pages/developers.
A free, downloadable implementation is provided in the example
solutions for Chapter 2, at
http://www.wiley.com/compbooks/dudney/jakarta/index.html under the
Chapters 2,3,4 link.
I'm a bit puzzled that you say that you can't get the user's locale in
your ActionForm. I would think you should be able to do something like
this in your Action to get the locale and set it on the form instance:
public ActionForward execute(...) {
...
Locale currLocale = (Locale)
request.getSession().getAttribute(Globals.LOCALE_KEY);
form.setLocale(currLocale);
...
}

Subject: Formatting form data inside the *view* (JSP's)
Thought I'd throw this out in the middle of the week again...
Kind of a conceptual question: how do you format Dates, Numbers,
Currencies, etc. for *form fields* inside the JSP?
I know I could do in in the ActionForm getters, but:
1. I don't know the locate of the user at that point
2. I'd have to recompile the ActionForm every time I want to
make a
change to the *view* - seems like a bad practice.
What I'm looking to achieve is something similar to fmt:format JSTL
tag,
where you can specify a format mask, or even a format style defined
elsewhere.
Thanks,
-Sasha

I would like to state a basic assumption I deduced in learning
struts, then

Assumption: ActionForm property getters and setters should
return and take
Strings.
My initial impulse was to try passing the actual data types
(Dates, Numbers,
etc.); however, the Struts mechanism seems to pass Strings to
the ActionForm
setter methods on form submission (which throws a conversion
Exception of
course). Then I tried making the setters take Strings, and
getters return
the actual data types, but this seemed to confuse the introspection
mechanism; plus I didn't see any way to apply formatting inside the
html:text tags (like you can in JSTL's fmt:format tags).
Question: How does one handle formatting data (custom
formatting or i18n)
for (pre/re)population of a form?
Ex.: An update form; a user's information is loaded from the
database into
classes (Strings, Dates, Numbers, etc.). If you want to format
this data,
you have to do it in the Model, as the ActionForm only takes and
gives
Strings - which seems to be a Bad Practice. Even if you had
additional
special setters for the explicit purpose of populating the
ActionForm from
original data types, you still don't know what Locale the
client is from.
Is my assumption incorrect? Is there a basic flaw in my
understanding of
the use of ActionForm? Or there an actual short-coming, and
workaround?
In short, How Can You Format Data For Strut's Form Tags Inside
The Actual
JSP :-) ?
Thank you for any input.

FreeMarker integrates quite well with Struts.

ANN] Struts-FreeMarker-JSP taglibs integration
Folks, The first release of FreeMarker 2.2 labeled production/stable is available. FreeMarker 2.2 may be of special interest to Struts users because it is the first template engine, to our knowledge, that supports the usage of 3rd party JSP taglibs. This means that you can have the cleanness and simplicity of a template engine like FreeMarker without giving up the ability to use powerful 3rd party JSP taglibs like Cewolf or SiteMesh and so on. You have the best of both worlds! See http://freemarker.org/docs/pgui_misc_servlet.html for more details about how to configure Struts for use with FreeMarker. There is also an example of struts usage in the distro. For those who don't know it, FreeMarker is a well-known, tried-and-true tool for doing page templates in Java. In practice, it is mostly used in the web space to get data from servlets into HTML pages. Aside from the ability to use JSP taglibs, FreeMarker 2.2 introduces a host of powerful new features. Here is a not-necessarily exhaustive list: namespaces -- macro libraries can be defined in separate namespaces so that different people can work on different pieces without any possibility of naming clashes. For more details, see: http://freemarker.org/docs/dgui_misc_namespace.html fine control of whitespace -- this has been the bane of template engines and a constant subject on mailing lists. We think we've really nailed this problem now. For more details, see: http://freemarker.org/docs/dgui_misc_whitespace.html more powerful macros -- Macros can defined with default parameters, and can be invoked with optional body content. For more details, see: http://freemarker.org/docs/ref_directive_macro.html Simplified syntax -- Macros and transforms are now invoked with a common syntax, so, despite the increased power, FM 2.2 is actually substantially simpler! For more details, see: http://freemarker.org/docs/ref_directive_userDefined.html clean interoperability with jython -- Of special interest to python fans, jython objects can be used transparently from within FreeMarker templates.

However, what I Retuirn is a login object specifying the username. Should I simply be storing This in the session? If so will this mean that this object will remain there until: 1. The session times out 2. I clear the session I want to be able to access the login object at ALL times. Will it be available no matter what? Jon. *-* Jonathan Holloway, Dept.

Nested Radio Buttons + Mutual Exclusion
Does anybody know how to use the nested:radio button component so That you can have mutually exclusive sets of radio buttons? Jon. *-* Jonathan Holloway, Dept. Of Computer Science, Aberystwyth University, Ceredigion, West Wales, SY23 3DV. 07968 902140 http://users.aber.ac.uk/jph8 *-*
Mutually Exclusive Radio Buttons
I wonder whether somebody could help me out here. I'm trying to create a number of radio buttons that have to be mutually exclusive. I know that its possible just by setting the property to be the same value for all but what if I'm using a nested:iterate tag? Surely this will result in the property being different for each of them because of the nested index, e.g. like property=Banana[0].ripe Rather than just: property=ripe which would allow mutual exclusion. Is there any way around this, Many thanks, Jon. *-* Jonathan Holloway, Dept.

Nested problem not finding the id
I'm currently using a nested:form part inside a nested:iterate loop
to display a number of different items along with a corresponding
edit and delete button for each item. The problem I have is that
I can't refer to the id of the item using:
nested:hidden property=addressId/
Could somebody tell me why it's looking for the addressId in my
initial person form instead of the nested Address object which
is contained with an arraylist in person, i.e.
PersonForm
Arraylist addressList
where addressList is of type person.
I get the following error message.
ServletException in:/person/addperson.jsp]
No getter method for property addressId of bean Personform
This is the following code segment, note that the nested:write
tag locates the address object correctly but the nested:hidden
tag within the nested:form tag does not. Do I need to use
nested:root or something?
nested:iterate property=addressList scope=session
tr

URL Rewrite Cookies
I'm still having problems with sessions here but I've kind of narrowed it down now. if I have a html:link tag in a page that is currently using Session A will it still use the same session if I use that link to get to another page? I'm assuming it uses URL rewriting instead when using html:link which is why the session ID changes when I look at the debug information on the Struts side. Can anybody shed some light here? My link by the way goes through the same action (instead of linking to another page) which simply returns a forward to the correct page. Jon. *-* Jonathan Holloway, Dept.

Iterate + indexed property arghhh....
Hello,
I wonder whether somebody can help, I'm using the logic iterate tag to
loop through a number
of items producing a delete button for each of the items. When the
delete button is
clicked I want to delete that particular item. Using the below:
html:submit indexed='true' onclick=return confirm('Confirm
Delete?'); property='action'
bean:message key=questionoption.button.delete/
/html:submit
I produce a list of buttons which SHOULD appear like follows:
input type=submit name=action[0] value=Delete
input type=submit name=action[1] value=Delete
input type=submit name=action[2] value=Delete
but instead the name appears like this:
input type=submit name=action[0] value=Delete
With [0] being outside the bracket.
Can anybody tell me why this is? Does it make a difference if I use '
to enclose the values
or whether I use to enclose the values. It would seem that it does so
does anybody know
the EXACT syntax for specifying a HTML submit button? Should I be using
a nested:submit
component? Does that really make any difference?
Also on the server side how would I catch which button has been pressed?
I can't use:
String action = (String)request.getParameter(action);
Because the index causes a problem,
Many thanks in advance for any help or tips you can provide me with,
this seems to be the last
part of my problems.
Jon.

Session Problems
Hi, I'm curerntly having problems with sessions in Struts. I have two JSP's both of which point to the same action. In my first JSP I have a number of basic properties and a list of addresses as shown below: *Name: Bill Blah *Age: 23 * Addresses (list) 23 Glamorgan Street | ER34 5RT | Edit | Delete 13 Glamorgan Street | ER34 6TT | Edit | Delete The addresses are simply displayed using a logic:iterate tag. I also supply a link on this page to add an address in a seperate page, this JSP allows a user to add an address to the list in the first page. When the page is submitted it is simply added to in the actionform. Once I've entered the new address using this second page I'm returned tot he first page where the new address is shown in the list of addresses. the problem I have is that when I add a second address it removes the first address and only the second address is shown here as: * Addresses (list) 13 Glamorgan Street | ER34 6TT | Edit | Delete instead of * Addresses (list) 23 Glamorgan Street | ER34 5RT | Edit | Delete 13 Glamorgan Street | ER34 6TT | Edit | Delete I'm assuming this is a problem with the session, could somebody please explain to me why this happening.

RE: Session Problems
The form bean is simply a standard action form, when its created
It simply does the following in the constructor
public PersonForm() {
addresses = new ArrayList(20);
}
To get the addresses and iterate through them I simply have:
/**
* Get Addresses
*/
public Object[] getAddresses() {
return (this.addresses.toArray());
}
When the second form is submitted the following method is called
In the AddAddressAction via the lookup dispatch action:
public ActionForward addAddress(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
//Check that the token is valid, if it is then reset it
if(isTokenValid(request)) {
System.out.println(Token is valid, resetting
the request);
resetToken(request);
}
else {
System.out.println(Token is invalid);
}
//Get the action form
PersonForm personForm = (PersonForm)form;
int addressId = (personForm.getNumberOfAddresses() + 1);
System.out.println(New id is + generatedId);
//Create the question option from the buffered values
Address address = new Address (generatedId, new
String(address));
//Add the question option to the action form
personForm.addAddress(address);
//Save a token for this request to prevent automatic
refreshing
//from submitting the request again
System.out.println(Saving the token);
saveToken(request);
//Now the address has been added return to the add person page
return (mapping.findForward(addPerson));
}
The address is added but the next time I try to add an address to old
one
Is overwritten..

LookupDispatchAction
Does anybody know why the following is casuing me so many problems.
I'm using LookupDispatchAction and have a number of methods defined
in my action class including an execute method. The problem is that
the execute method ALWAYS gets executed and not the intended method.
I have in the addbanana.jsp:
html:submit value=Add Banana property=action/
and in Struts-config:
action path=/addbanana
type=com.example.AddBananaAction
name=BananaForm
input=/addbanana.jsp
scope=session
parameter=action
/action
In my action class I've defined the following:
public ActionForward addBanana(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws
IOException, ServletException {
return (mapping.findForward(success));
}
public ActionForward deleteBanana(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws
IOException, ServletException {
return (mapping.findForward(success));
}
/**
* Get key method map just obtains the map that maps the button
* text onto the particular method in this action
* @param mapping is the action mapping
* @param form is the action form
* @param request is the http request
*/
protected Map getKeyMethodMap() {
Map map = new HashMap();
map.put(Add Banana, addBanana);
map.put(Delete Banana, deleteBanana);
return map;
}
/**
* Execute method
* @param mapping is the information regardin gthe URI mapping and the action
* @param form is the action form used
* @param request is the request
* @param response is the response
* @return the action forward, a destination to forward the user onto (eg another JSP)
*/
public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws IOException,
ServletException {
Logger.logInfo(Execute Called);
//We can now put these bits in the database
return (mapping.findForward(success)
}
Does anybody know why EXECUTE is called but the intended ADDBANANA method is not
called?

LookupDispatchAction
Ok the reason I had just put strings in the Map was because of
Lack of internationalisation, I've now done this but still I get
The same error that of a NullPointerException. I'm assuming this
Is because of a method not found error from my ServletException
Output in Tomcat... (See attached) Am I correct in assuming that
map.put( button.banana.add, addBanana );
maps onto the method..
public ActionForward addBanana(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws
IOException, ServletException {
return (mapping.findForward(success));
}
I've simply stuck super.execute() in my execute method and also
Tried removing the method as well but I still seem to get the
Following exception *sigh*. Can anyone suggest whats wrong?

RE: LookupDispatchAction
Ok, here goes... I've definately defined the internationalization Stuff in ApplicationResources. Note the struts config bit below And the fact that I've specified the scope as session, does this make a difference? action path=/addbanana type=com.example.AddBananaAction name=BananaForm input=/addbanana.jsp scope=session parameter=action forward name=success path=success.jsp/ /action My JSP has the bit... html:submit property=action bean:message key=button.banana.add/ /html:submit Is this wrong for a submit button? Should I be specifying a value Attribute? If so how do I pass the bean:message bit in, is it this instead html:submit property=action value=bean:message key=button.banana.add/ /html:submit Finally application resources contains... button.banana.add=Add Banana Many thanks, Jon. -Original Message- From: Wendy Smoak [mailto:[EMAIL PROTECTED]] Sent: 13 February 2003 00:28 To: 'Struts Users Mailing List' Subject: RE: LookupDispatchAction Ok the reason I had just put strings in the Map was because of Lack of internationalisation, I've now done this but still I get The same error that of a NullPointerException.

Adding a new object to a collection in an actionform
Does anybody know how to add a new Object to a collection
that exists in an ActionForm.
public class MonkeyForm extends Actionform {
public ArrayList bananas;
...
...
public void setAddBananaForMonkey(Banana newBanana) {
bananas.add(newBanana)
}
}
I know I can create an empty object just by doing this:
nested:submit onclick=addmonkey.do
property=addBananaForMonkey
value=Add New Banana For Monkey/
But how do I go about creating a new banana with initialized properties
that come from a nwe form on another page. Is it possible?
I need the new form because I want the user to enter the details for
the banana BEFORE it is created as blank in the actionform.
It would be ideal if I could enter these new details in a popup window
of some sort but how do I go about doing this,
Many thanks in advance,
Jon Holloway.

Forms and multiple buttons
I've successfully built a page that iterates over a nested arraylist displaying the contents of the arraylist in the following way --- | Title | Code | Available? | Edit | Remove | |---| | rara | 1220 | X | Button | Button | | asdd | 1435 | X | Button | Button | --- In the case of the edit button I want to display an alternate screen that allows the entry of the details (title, code and available). In the above table I just want them to be read only. I also want the remove button to remove the selected object from the ArrayList. Can anybody tell me how I shoudl go about doing this? Is it a case of embedding id's in the button and manipulating the array list using these ids and an action? If so how do I partition my action up into various parts to achieve this? Is it a simple case of using dispatchAction and passing the id in the query string? Many thanks in advance, Jon. *-* Jonathan Holloway, Dept.

Re: Nesting forms
You don't actually need to create three forms. All you need to do is to create one action form for your top level form, in your case LineItem. The other two are standard Java classes, just make sure they implement Serializable. You can just refer to these in your main form in the following way LineItem ArrayList shippingList then in your Shipping java object just have Shipping ArrayList billingList The code is simple to loop through and display these and it simply involves sticking nested:iterate tags in your JSP to loop through the fields within the other objects. Hope that starts you off, you don't actually need to piss about with the struts-config.xml file at all apart from declaring your initial actionform there, hope that helps you out.

RE: log4j problem
With struts1.1b2 I think you need to get another commons-logging.jar first.
If it can help, Struts will use your log4j conf file if it finds it. In this
conf file you need to set specifically org.apache.struts to have a log level
as WARN for example (as shirishchandra sakhare said!).
In your webapp init servlet, you will have something like this:
PropertyConfigurator.configure(path_to_your_log4j_conf_file);
and the conf file could look like this:
# Set root logger level to DEBUG and its only appender to A1.
log4j.rootLogger=INFO, A1
# A1 is set to be a ConsoleAppender.
log4j.appender.A1=org.apache.log4j.ConsoleAppender
# A1 uses PatternLayout.
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%d{dd/MM/yy HH:mm:ss} %-5p %C{1}
%x - %m%n
log4j.logger.org.apache.struts=WARN
hope this helps.

Re: A Useful Struts Resource
Struts doesn't deal with client side browser stuff, your right, but for those of us building complex user interface components in a browser we have to use something. Making the same functionality available in desktop applications to web appliactions is a big problem and we need a way of solving this. HTML doesn't do the job on its own and so we need a scripting language like Javascript. The point I was trying to make was if the Javascript used is compatible with Netscape (and possibly Mozilla) as well as IE which is what I was viewing it on. Alternatively another method of complex client side user interfaces is to use flash remoting and link it through to Struts http://www.javaworld.com/javaworld/jw-01-2003/jw-0117-flash.html? I think this has already been done but can't seem to find the link.

JNDIConnectorPlugin Example - C.Caveness Book
Has anybody attempted to use the example in the Programming Jakarta Struts book for the JNDI stuff. It defines two things: a) A JNDIConnectorPlugin class that takes the properties from the struts-config.xml configuration file. b) An EJBHomeFactory that uses the JNDIConnectorPlugin to lookup a reference to an Enterprise Java Bean. The JNDIConnectorPlugin simply takes the values from the config file and inserts them into the servlet context for retreval by any servlet via: getServlet.getServletContext() The problem with this is that it needs to call this from the EJBhomeFactory which is simply a singleton class and has no reference to the Servlet Context. In the book by C.Caveness he retrieves these properties from a properties file but what I want to do is to get them from the servlet context (which JNDIPlugin has used to place the values). Is there any way of doing this from a standard class or does EJBHomeFactory need to be implemented as a servlet? Is this the best approach to take when looking up EJB's form an action class via the jndi properties? It seems to me like it is and I don't want to hardcode the values in the EJBHomeFactory rather take them from the servlet context. Also when it comes to the EJBHomeFactory I only want to cache references to one EJB namely my central facade session bean. Does anybody know whether it's possible to resuse the same instance (that's cached) in different action classes or does it have to be a seperate instance for each action class (in a similar way to which a database connection pool works). Does anybody have any other better methods of looking up EJB's form action classes? Many thanks, Jon. *-* Jonathan Holloway, Dept.

RE: Obtaining the ActionServlet context from a utility class
I'm embedding the attributes themselves in the struts-config file and passing these to a custom struts plugin that I've created. I then embed these attributes in the servlet context on startup of the class (i.e. in the init method). The thing is I have another factory class that needs access to the servlet context and that's the problem I have, getting hold of the action servlet before obtaining the servlet context to retrieve the attributes. I sit possible just to embed the functionality of my factory class in my plugin class and simply call the methods in the plugin class. I didn't think this was the right way hence the creation of a factory class and a plugin class to do the job. I don't want to use the utility in non Struts related classes either, this is purely for my Struts action classes use.

What about an extensive UserProfile object graph, populated after the authentication process, from which a vast amount of personalization and customization content originates? I work for a **really** large J2EE shop with many WebApps and we are in the endless pursuit of the one company image. There seems to be no way to meet that requirement while also adhering to Servlet requirement of not sharing objects between WebApp sessions (I know, I know ... it's right there on page 51 of the J2EE Servlet Spec PDF.) EJBs might go a long way to helping this, but precious few of the WebApps actually use them ... somebody said something about something that some else said about something they read from someone who sat next to someone who heard about someone who tried something sometime ago, somehow, somewhere, someway ... And now it's policy. Besides, what if all that needs to be shared is the Struts SkinChooserFormBean? Is that the ideal candidate for an Entity Bean? So, is this the cross-roads of the real-world and the J2EE Servlet Spec? Maybe we should think about some methodical means of being able to share a given object or object graph across WebApps in a non-strategic, almost casual context. Something like contacting a broker, asking it to contact the WebApp that is registered as primary for a given type of object (e.g., UserProfile, SkinChooserFormBean, etc.) and having it extract and deliver a ReadOnly copy of the object?

RE: Complicated Web Interfaces?
Ok in principle then it seems fine it's just I don't like the fact that a scripting language whether client or server side can be embedded in the presentation logic, it still seems like a bit of a workaround. I've wondered about whether the Model2X approach and the Model 2 approach for some while now and it seems like the latter doesn't seperate the concerns as much as Model 2X. The only thing that makes me doubt this is the fact that Sun and yourself have gone this way via the Model 2 approach with Java Server Faces rather than the Model 2 approach. Is there any particular reason why this method is preferred over the Model 2X approach? Jon. -Original Message- From: Craig R.

Surely embedding javascript in a JSP is just as bad as embedding scriptlets in a JSP? Or am I missing the point here somewhere :) ? The big difference is that scriptlets execute on the server, as the page is being generated -- and have access to the entire object model of your application (leading to the temptation to embed business logic there). JavaScript doesn't execute on the server, it executes on the client, and doesn't have direct access to your business objects. Embedding JavaScript to enhance the user experience (i.e. improve the quality of the presentation) is fine. An example of this is the client side validation JavaScript that can be created by the Validator Framework -- this improves life for the user by catching errors earlier. Using JavaScript to send background HTTP requests that grab stuff directly from the database (bypassing the normal control flow) and changing the contents of select lists is a little more iffy -- but some intranet based apps (where the 100mbps network makes it pretty fast) will undoubtedly use such techniques to more accurately simulate what a GUI app can do. You can still flow such requests through the controller servlet, though -- to special actions that just return data instead of HTML -- and that seems fairly reasonable. Jonathan Holloway.

I believe the action looker-upper ignores .do part in your action in the form tag but the correct syntax would be : html:form action=/edit /html:form Since your action config specifies /edit your form tag should also specify /edit. I think that is what is confusing the lookup. It's looking for a mapping of /edit.do (that doesn't exist) where the action servlet disregards .do part and properly dispatches. hth danny -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
html:form frustration
bean definition
ActionFormBean formBean =
formBeans.findFormBean(mapping.getName());
if (formBean == null) {
JspException e = new JspException
(messages.getMessage(formTag.formBean,
mapping.getName()));
pageContext.setAttribute(Action.EXCEPTION_KEY, e,
PageContext.REQUEST_SCOPE);
throw e;
}
// Calculate the required values
name = mapping.getName(); // --- Line 803
scope = mapping.getScope();
servlet = mappings.getServlet();
type = formBean.getType();
Any suggestions would be *greatly* appreciated!
Thanks,

RE: html:form frustration
Thanks for the clarification, Kevin. I misunderstood what Danny was saying in his code snippet. After looking at it again, I noticed that he'd added the name attribute to the action mapping for the /load action... Unfortunately, that isn't my problem. /load.do doesn't display a form. All it does is load a list of values and stores them to the session context (so they can be displayed in a select box by edit.jsp). It then forwards to the edit.jsp. It's the form on edit.jsp which is the problem. (if I take out the html:form tag and replace it with an html:iterate which iterates through my list, it works fine) For some reason, it's having trouble with lookup on the /edit.do action specified in the html:form tag. Looking at the /edit action-mapping entry, it DOES have the name=editForm definition. Jonathan -Original Message- From: Kevin A. Smith [mailto:[EMAIL PROTECTED]] Sent: Thursday, September 19, 2002 3:37 PM To: Struts Users Mailing List Subject: RE: html:form frustration That just associates a logical form name with the underlying Java implementation.

But for some strange reason the HttpSession I create in my LogonAction loses an attribute (The UserBean) in the next request (only with Resin)! Are there any JSPs involved in your testing? They always seem to create a session when they start up. If for some reason (short timeout or otherwise) the initial session you created and put the user bean into was invalid when a JSP started, it would create a new (empty) session, which could be what you're seeing in that second servlet. The locale attribute probably comes from a html:html locale=true tag in your JSP (assuming you are using a JSP). Do try and set the session timeout in web.xml (as you mentioned).. a very short session timeout is one possible explanation for what's going on. I don't know if this will help you solve the problem, but that's my best guess at what's happening to your session. Good luck with it! -- Jonathan Fuerth - SQL Power Group Inc.

I'm guessing the LOCALE attribute is coming from the web browser! I also tried setting the session-timeout to 30 minutes in web.xml and that didn't work either. No, the session is stored only on the server side. The web browser has no direct control over what's actually in the session.. it just remembers a session key which helps the server figure out which session object to use for the current request. Your browser can make the whole session seem to go away (by refusing to remember the session key) but it can't add or remove items that are stored inside a particular session. But this is where things get really strange! I started up K-Meleon (Mozilla browser) to check and see if MS-IE was sending my location in the request (Hence the LOCALE attribute) and everything worked just fine! Not one problem! I can login/logout etc. UserBean is getting saved in the Session. Everything works as expected! Back to IE and it still doesn't work. IE is setup to check for newer page version with each request. So it's not a problem with the cache. Maybe we've both overlooked the obvious: Is it at all possible that you've got cookies turned off in your MSIE privacy options? That's what it sounds like at this point. -- Jonathan Fuerth - SQL Power Group Inc.

problem with error messages
Hello,
I am getting the following error message on one of my
jsps:
javax.servlet.ServletException: Exception creating
bean of class com.valleyrec.toteboard.beans.Toteboard:
{1}
I know from browsing the struts source that the {1}
should be the forward.forward property from
org.apache.struts.taglib.logic.LocalProperties.properties.
That message is:
Exception forwarding for name {0}: {1}
with the {0} and {1} replaced by parameters. I've had
this problem across multiple versions of struts
(including today's cvs and a few daily builds from
last week). Does anyone know why I'm not getting the
correct error messages? Could this be a bug, or do I
have some sort of configuration error?
