Re: Curious how others handle these situations..
Hi Rick, This is the approach what i have taken.. 1) I had all forms set to Session Scope in the Struts config. 2) Maintain an "actionStack" form variable in all the form, which would keep track of all the required actions as CSV in FILO order(Login,PlayerSearch,EditPlayer,..) 3) Maintain an "action" Variable in each form where ever needed to put the action into the stack. (we had a jsp tag written to put the "action" value to the actionstack for each form submitted as request attribute & put this actionStack in request scope for next form) 4) when u need to go back to the previous action fetch it from the actionStack and forward it to that action path(also remove that action from the stack). This also helps u to even facilitate back button on the menu which will be a very generic approach.

Re: Curious how others handle these situations..
Hi Rick, I did this for a large application where there were a lot of different record types with various linkages much as your roster has with players, and where said linkages could nest quite deeply. You will need to use the session to do it cleanly. The idea is to somehow keep a stack of ActionForms. Another need I had was to allow several such page-flows to go on simultaneusly in multiple windows (which session scoped forms would have problems with). In my case I went so far as to implement a new scope - the 'operation context' - which is basically a sort of sub-session identified with a unique id which is its attribute key in the session, passed in the request url. It consists of a map and some other properties and methods. I overrode the request processor to allow for my actionForms to be stored in this context. I also needed to bang up a fair bit of support code to deal with things like cleaning up the operation contexts at the appropriate time etc... The operation contexts can be stacked, and the term I came up with to describe the act of putting aside the current one to go work on another with the ability to come back later was "diversion", so when the user "diverts" to another page the dispatch action will note that they are diverting to X (based on some hidden field set when the user clicks the link or button to divert) , will push a new operation context onto the stack for that operation context id, and forward to the appropriate action (for which the requestProcessor will instantiate the new form and store it in the operation context as normal). When the user has finished playing with X (ie they save the changes or cancel) the action will pop that operationContext replacing the previous one at the top of the stack and a url or forward name or such like stored as a property in that operation context tells it which action to go back to after that to continue where the user left off. Obviously since your using a stack you can divert multiple levels as deep as you want... Since the operation context has its own attributes (lie session and request) one can also use these to pass info between the actions and then do a redirecting forward (where the operation id is encoded as a url parameter). The application I did this for is quite complex and has a lot of configuration that can be done through the ui. There are many different record types that the administrator can create and edit, and most have relationships to various other records (that have their own dependencies ad infinitum...) that would normally have to be created first, making the process quite tedious. By implementing 'diversions' however I was able to make the application practically guide the admin users through the process almost like a wizard but much much more flexible. Since there arent all that many admin users for any particluar deployment of the app, the memory overhead for using the session like this wasnt significant, while the huge boost in user-friendliness was. :-) In your case you probably dont need to go as far as I did. You could perhaps just keep track of the pages in the stack in a session scoped collection and override the requestProcessor to look in that collection for the form instead of instantiating it. If it finds a form in that collection it can use that (storing it under the normal key in the session (or even request actually. Hmm) where the other strust things (like tags) will look. (You will note we need to go via an action rather than hitting any JSPs directly here so that we make a trip through the requestProcessor where our code will find the form and put it in the appropriate place!) hth Andrew Rick Reumann wrote: To cut to the chase.. Imagine a hypothetical UI where you have checkboxes next to football players and by checking the boxes and hitting 'save' you would be saving a roster. Typically you'd have a FormBean to capture this information and probably a "RosterAction". Now also imagine that next to each player on the above list where you set up the roster, there is also an 'edit' button that lets you edit the player. In the application this will not be the only way you can get to edit a player so its behavior needs to be self contained (ie "PlayerAction"). The question I have is, how do you guys handle situations where you need to get 'back' to different pages depending on where the user was? For example, in the above scenario, after a user edits a player, I want the user to be forwarded "back" to the same roster selection screen with what he was working on - what he's checked - still selected. However, if maybe the user is getting to the edit a player functionality from a search screen of search results where he searched for a player to edit, I want the user returned to that screen. The only clean way sort of clean way I've found to accomplish this is to rely heavily on the use of Session. For example if the Session is used t
Re: [Struts-Chain] how to use another chain for preprocessing?
To chain actions, you simply return a non-redirect ActionForward which points to a Struts action path. This is chaining (where a redirect isn't) because it results in the ActionServlet triggering a second "run" through the RequestProcessor's processing flow. OK, that's what I was thinking, along with using the trick to set the arguments on your forwards (see http://wiki.apache.org/struts/ForwardingWithDifferentParameter) This can have some unexpected side effects, which is one reason it's not considered "supported behavior". Also, as Ted notes on the references Wiki pages, when people chain actions, it is often (though not always) because they haven't got a clean controller architecture. Fair enough. I notice that the email from Craig included in that page is over two years old and heavily references the transition from Struts 1.0 to Struts 1.1; is that still useful this far on? I don't think so. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

JoAnn, Please don't take this wrong, but it is considered quite rude to email the list in such quick succession. Believe it or not, most of the people on the list actually work and have things to do other than check for new messages every 2 minutes. In fact, it's only by people volunteering to answer questions that questions get answered. Nobody gets paid to do it! My apologies if you feel my response is rude. It's not meant to be rude. It is meant to help you realize that, by spamming the list like you did with this message, you're potentially alienating the very people who might be able to help you. In other words, you're likely to get ignored. Most questions get answered pretty quickly, considering nobody is paid to answer questions.

How to use tiles to render dynamic pages
Hi, We have an application that displays 4 columns of data in a page. The number of columns is configurable by the admin and also by the user. The minimum number of columns displayed is 2. If a column is not displayed then the space allocated for it needs to be taken up by other columns. Is there an easy way of doing this using tiles? Do I have to write custom code in my JSP to look up the user/admin choices and then display the columns and also resize them? Or is there any built in controller that can help me with that?

Re: Serious performance impact with iterator
If you are using tomcat you could look at the trimSpaces option for JSP page compilation in server.xml There are also filters that can be used to compress the page as it is being sent to the browser. You can also try writing out tags differently to minimise spaces produced in source eg ... ... ... The spaces inside a tag will not be output to the page. So by putting the indentations there, you can see them in the code but not the html that is sent to the browser. Eg abc will produce 'abcabcabcabc' where as abc will produce 'abc abc abc abc' JoAnn Lemm wrote: Hey All, I'm wondering if anyone else is seeing this impact.

which tries to insert this value in database,
If this value exist i get an SQL error, then i have to
display this SQL error on the jsp and also the
dropdown box,
but when i get back to my jsp the dropdown box is
empty, i.e. the arraylist is empty.
How do i retain this arraylist in my Action class??
In my action class i have the following code,. if
there is no error i remove the bean from request scope

Struts form problem.

It's the exception, when I try to open a jsp from de browser: The exception: -- (util.RequestUtils 306 ) Error creating form bean of class ar.com.byosoft.webportal.forms.LoginForm java.lang.NullPointerException at org.apache.struts.config.FormBeanConfig.createActionForm(FormBeanConfig.java:214) at org.apache.struts.util.RequestUtils.createActionForm(RequestUtils.java:294) at org.apache.struts.util.RequestUtils.createActionForm(RequestUtils.java:193) at org.apache.struts.taglib.html.FormTag.initFormBean(FormTag.java:453) at org.apache.struts.taglib.html.FormTag.doStartTag(FormTag.java:433) at org.apache.jsp.jsp.common.left_jsp._jspx_meth_html_form_0 (left_jsp.java:360) at org.apache.jsp.jsp.common.left_jsp._jspx_meth_logic_empty_0 (left_jsp.java:335) at org.apache.jsp.jsp.common.left_jsp._jspService(left_jsp.java:116) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:94) at javax.servlet.http.HttpServlet.service(HttpServlet.java:802) at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:324) at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:292) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:236) at javax.servlet.http.HttpServlet.service(HttpServlet.java:802) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:237) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:157) at org.apache.catalina.core.ApplicationDispatcher.invoke(ApplicationDispatcher.java:704) at org.apache.catalina.core.ApplicationDispatcher.doInclude(ApplicationDispatcher.java:590) at org.apache.catalina.core.ApplicationDispatcher.include(ApplicationDispatcher.java:510) at org.apache.jasper.runtime.JspRuntimeLibrary.include(JspRuntimeLibrary.java:966) at org.apache.jasper.runtime.PageContextImpl.include(PageContextImpl.java:581) at org.apache.struts.tiles.TilesUtilImpl.doInclude(TilesUtilImpl.java:101) at org.apache.struts.tiles.TilesUtil.doInclude(TilesUtil.java:137) at org.apache.struts.taglib.tiles.InsertTag.doInclude(InsertTag.java:758) at org.apache.struts.taglib.tiles.InsertTag$InsertHandler.doEndTag(InsertTag.java:890) at org.apache.struts.taglib.tiles.InsertTag.doEndTag(InsertTag.java:460) at org.apache.jsp.jsp.layout.layout_jsp._jspx_meth_tiles_insert_1 (layout_jsp.java:194) at org.apache.jsp.jsp.layout.layout_jsp._jspx_meth_html_html_0 (layout_jsp.java:124) at org.apache.jsp.jsp.layout.layout_jsp._jspService(layout_jsp.java:81) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:94) at javax.servlet.http.HttpServlet.service(HttpServlet.java:802) at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:324) at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:292) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:236) at javax.servlet.http.HttpServlet.service(HttpServlet.java:802) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:237) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:157) at org.apache.catalina.core.ApplicationDispatcher.invoke(ApplicationDispatcher.java:704) at org.apache.catalina.core.ApplicationDispatcher.processRequest(ApplicationDispatcher.java:474) at org.apache.catalina.core.ApplicationDispatcher.doForward(ApplicationDispatcher.java:409) at org.apache.catalina.core.ApplicationDispatcher.forward(ApplicationDispatcher.java:312) at org.apache.struts.action.RequestProcessor.doForward(RequestProcessor.java:1056) at org.apache.struts.tiles.TilesRequestProcessor.doForward(TilesRequestProcessor.java:261) at org.apache.struts.tiles.TilesRequestProcessor.processTilesDefinition(TilesRequestProcessor.java:237) at org.apache.struts.tiles.TilesRequestProcessor.processForwardConfig(TilesRequestProcessor.java:300) at org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:231) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1158) at org.apache.struts.action.ActionServlet.doGet(ActionServlet.java:397) at javax.servlet.http.HttpServlet.service(HttpServlet.java:689) at javax.servlet.http.HttpServlet.service(HttpServlet.java:802) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:237) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:157) at org

Re: ActionMessages question (simple)
Caro Vinicius,
Your java code is fine. But you got confused on the struts tags.
If you want to display ALL the messages you have, (that's probably what
you need) one under the other, separated by 's, you would use:
But if you only want to display that "removido" message when it exists,
you can use:
The html:messages tag loops over all of the items in your ActionMessages object.
The "id" is the label of the "current message instance" in the loop.
The "name" in the bean:write tag in this case corresponds to the label you gave to "current
message instance".
Um abraco,
Thompson

This is the validate method in my form:

This is the mapping inside my struts-config.xml:
I'm not using the tag (I believe it's not mandatory to
use one).
Am i missing something?

Re: Curious how others handle these situations..
Hubert Rabago wrote the following on 10/25/2004 11:54 AM: First, allow the editing of a player from one location only. This way, I only need to get back to that page. I 'try' to do this also. Second, if you're on the roster screen, and you want to edit the player, I'll let you do that, but in a separate window. I like this approach also and is what I decided to do for this one app (not related to nfl or rosters:). I was initially going to try to avoid the opening of extra windows, but in this case it makes life so much easier. However, when I absolutely need to support this, then the location to forward back to (ain't that an oxymoron?) gets included as an optional request parameter. If it's present, that's where I forward to after the edit. If it isn't there, I forward to the default "view" page for that data. Just to clarify, the optional parameter isn't a dynamic value that gets calculated into a view. It's a static label, so I still control which views an action forwards to, and I can still see them all in my config file. Right. The problem/ugly part is having to make sure you set up, in a seeminly unrelated action, all the stuff the action you will forward to also needs to perform its task. I suppose the difference between this and your session+mapping approach would be, you'd be duplicating info on the config, whereas I'll just have an if statement on my action. In both cases, each "edit" link/button/form would have to be aware of what it's got to do to get back control after the edit operation. Yup. I only opted for the config approach since later on if you didn't need the 'if' logic, I found it cleaner to just delete the config entry versus having to mess with the action if logic - although like I mentioned above, I'd still have to have my action aware of where it's going to next so I'd still end up having to modify the action if things changed, so the config approach doesn't buy much anyway:) Thanks for your input. I appreciated it. -Original Message- From: Rick Reumann [mailto:[EMAIL PROTECTED] To cut to the chase.. Imagine a hypothetical UI where you have checkboxes next to football players and by checking the boxes and hitting 'save' you would be saving a roster. Typically you'd have a FormBean to capture this information and probably a "RosterAction". Now also imagine that next to each player on the above list where you set up the roster, there is also an 'edit' button that lets you edit the player. In the application this will not be the only way you can get to edit a player so its behavior needs to be self contained (ie "PlayerAction"). The question I have is, how do you guys handle situations where you need to get 'back' to different pages depending on where the user was? For example, in the above scenario, after a user edits a player, I want the user to be forwarded "back" to the same roster selection screen with what he was working on - what he's checked - still selected. However, if maybe the user is getting to the edit a player functionality from a search screen of search results where he searched for a player to edit, I want the user returned to that screen. The only clean way sort of clean way I've found to accomplish this is to rely heavily on the use of Session. For example if the Session is used to store search results and the roster. You can have mappings that look like: If you don't use the Session above, all have to make use of fowarding back to other actions and having to set up a bucnh of parameters before doing so.

RE: Curious how others handle these situations..
I personally try to avoid situations like this. There are a couple of ways I avoid it. First, allow the editing of a player from one location only. This way, I only need to get back to that page. Second, if you're on the roster screen, and you want to edit the player, I'll let you do that, but in a separate window. Perhaps the player's name doesn't even link to the edit form, but instead to a view form (or in your case, I'll have a "view" button instead of an "edit" button, though I've always gone the link route). From there you can click on Edit, make your changes, get back the view form, and close the separate window if you want. However, when I absolutely need to support this, then the location to forward back to (ain't that an oxymoron?) gets included as an optional request parameter. If it's present, that's where I forward to after the edit. If it isn't there, I forward to the default "view" page for that data. Just to clarify, the optional parameter isn't a dynamic value that gets calculated into a view. It's a static label, so I still control which views an action forwards to, and I can still see them all in my config file. I suppose the difference between this and your session+mapping approach would be, you'd be duplicating info on the config, whereas I'll just have an if statement on my action. In both cases, each "edit" link/button/form would have to be aware of what it's got to do to get back control after the edit operation. hth. -Original Message- From: Rick Reumann [mailto:[EMAIL PROTECTED] To cut to the chase..

requiredif combined with other validation rules
hi. i'm using struts 1.1 and have a question about combining requiredif
with other validation rules. i have
field[0]
country
fieldTest[0]
EQUAL
fieldValue[0]
840
mask
${uszipmask}
if a user chooses a country other than 840 (usa) and leaves the zip blank,
then the form passes validation. however, if he chooses a country other
than 840 and enters something in the zip field then the mask is applied to
that value. i would like the mask rule to be bypassed also if the country
isn't 840. is this possible?

RE: tab UI controls for struts
I had a look for such things a few weeks ago. My requirement was for a server side implementation - i.e. one that didn't execute the content of hidden tags. I couldn't find anything that met that requirement. I did find a pretty cool looking client side implementation at http://www.pintexx.com/ I've implemented my own tab control as a bunch of custom tags. There is no inherent dependancy on Struts - the state is maintained in hidden html fields & a change of tab is indicated via request parameters. I'm not in a position to share any of this code I'm afraid, but I'm more than happy to discuss the design etc. Paul > -Original Message- > From: kjc [mailto:[EMAIL PROTECTED] > Sent: Monday, October 25, 2004 4:36 PM > To: [EMAIL PROTECTED] > Subject: tab UI controls for struts > > > looking for a tab UI control for use with struts. > > > - > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > ** Axios Email Confidentiality Footer Privileged/Confidential Information may be contained in this message.

If I use getContentType() of FormFile, does it give the same results on different operating systems that is if the client is using different operating systems. Yes, the client determines by its own mechanisms what MIME type to send. For a specific example, MSIE insists on labeling all JPEG images as "image/pjpeg". This is annoying because we use a third-party application which explodes when it tries to process progressive JPEGs. We've had to institute a process which "resaves" all JPEGs explicitly as not-progressive. It would be nice if MSIE would tell the truth, so we could only use that process when we really need it, although I suppose given how badly the third-party app response to PJPEGs, it's probably safest that we do this anyway. Does the change in server OS affects the getContentType() result. No, it shouldn't, because it simply accepts whatever is sent by the client.

Object size/memory usage

}
public calss Object2{
private name;
private id;
private depetId;
private country;
private jobFamily;
private isActive;
. (there are another 100 attributes)
}
Then I create
Object1 obj1= new Object1(); and set all attributes (name, id, depetId)
of this object.
Object2 obj2 = new Object2(); and then set the first three
attributes(name, id, depetId).
My question is that is obj1 and obj2 of the same size or usage of
memory?

Hi Craig. I was hoping you could explain 1) how people typically chain actions in struts 2) why it is a bad idea I have some ideas for answers to both questions but I'd like to hear what you think. Here's a page in the Wiki about this eternal question: http://wiki.apache.org/struts/ActionChaining To chain actions, you simply return a non-redirect ActionForward which points to a Struts action path. This is chaining (where a redirect isn't) because it results in the ActionServlet triggering a second "run" through the RequestProcessor's processing flow. This can have some unexpected side effects, which is one reason it's not considered "supported behavior". Also, as Ted notes on the references Wiki pages, when people chain actions, it is often (though not always) because they haven't got a clean controller architecture. I notice that the email from Craig included in that page is over two years old and heavily references the transition from Struts 1.0 to Struts 1.1; is that still useful this far on? I'm not sure who the "I" is in the lead-in to that page is.

Re: request question
If your trash-can button is using a link, you need to encode the request
parameters into the link when you generate the JSP page. If your
trash-can button is submitting a form, you need to create elements in your JSP page for each request parameter.
I would recommend the latter approach, because it's the only way you can
use the POST method to submit your request, and that's the recommended
approach for any operations that attempt to modify the data in the system.

Re: Problem in Locating a properties File (Not application.properties)
Caroline,
You need to use getResourceAsStream() method from
ServletConfig class.
request.getSession().getServletContext().getResourceAsStream("/filename.properties");
This will return you an InputStream that you can pass
to Properties.loadProperties() and make it work.
The "/" represents the context root.

Re: [Struts-Chain] how to use another chain for preprocessing?

Hi Craig. I was hoping you could explain 1) how people typically chain actions in struts 2) why it is a bad idea I have some ideas for answers to both questions but I'd like to hear what you think. Thanks, Bill The code that is in the repository now has focused on providing a chain implementation that is fundamentally backwards compatible with existing Struts 1.1/1.2 functionality. As such, it emulates the current RequestProcessor architecture by passng all requests through a single commonly configured pipeline (which can, of course, be customized). Going beyond strict backwards compatibility, there's lots of options: * A chain can already invoke another chain using the generic LookupCommand capability. The "other" chain's name can be determined either literally (via the "name" property) or indirectly (via the "nameKey" property, naming a context property where some other processing logic has stored the name of the chain to be executed). * Given this, it would be trivial, for example, to create a chain equivalent to the standard DispatchAction, which based the name of the chain to run on some request parameter, or other incomding characteristic on the request. In the "servlet-standard" chain, this technique is used to execute a user-defined preprocess chain if there is one, ignoring it otherwise. * Alternatively, it would be possible to set things up so that the name of the action implicitly selects a correspondingly named chain (if there is one); defaulting to the standard chain if there is nothing special. That way you could customize the processing of individual actions without having to affect all of them. * Regarding chaining of actions themselves, if you are using the standard request processing chain that remains as bad an idea as it has always been in Struts, and I don't see any reason to make it easier with chaining than it is today. Instead, a different approach is likely to be better -- for example, building a chain that forwards to a view named "foo" could automatically look up a setup chain (specific to that view) and execute it if it's there. This would likely eliminate many occurrences of the "setup action --> view --> process action" design that you see in lots of Struts code. What a chain does is totally up to who designs the chain. Once you free yourself from a requirement to be backwards compatible (leaving the existing servlet-standard chain there for people that *do* want that), there's a lot of room to innovate. So, the answer to nearly all of yor questions is "yes, you can do that if you want to." Craig On Fri, 22 Oct 2004 20:23:28 -0400, David G. Friedman <[EMAIL PROTECTED]> wrote: I'm curious about Struts-Chain and have read through the 1.2.4 source on it plus the 1.3 SVN repository. I don't see anything suggesting how to make my action chain itself to another action in the struts-config.xml example. Nor do I see anything suggesting how to have an action be processed by a chain other than the default chain. Is struts-chain supposed to be as one chain per web.xml pattern matching? Are the chains supposed to do that and use a common struts configuration object? (I.e. Just /do/whatever invokes chain a but mapping /dothis/whatever3 invokes a different chain? Thanks for any help.

Re: : pre-populating fields from the Action java code
Thanks. Yes, I can reference the bean name from every or
other element inside of the . But if there are lots of
fields, it would be nicer to only write the bean name once, in the
tag.

I have a question about pre-populating the fields of a form you display

determines the form bean's name automatically based on the
specified action and the settings in struts-config.xml. But, what if you
wanted a web page with multiple forms all pointing at the same action?
For example, an airline ticket website might display 10 possible flights
and have a button to book each flight. All the buttons point at the same
bookFlight action, but the flight number attribute is different.
In other words, how do I implement the code below without using the
"name" (or beanName) attribute:
MyAction.java:
request.setAttribute("inputForm1", new InputForm("$499", "flight 31"));
request.setAttribute("inputForm2", new InputForm("$599", "flight 32"));
request.setAttribute("inputForm3", new InputForm("$699", "flight 33"));

Unless I am misunderstanding what you are looking for, that is what the
arg0-arg4 attributes are for, to insert up to 5 parametric replacements.
In case I have goofed, check the docs at:
http://struts.apache.org/userGuide/struts-bean.html#message
If you prefer to use JSTL over struts tags when possible, the JSTL
equivalent is the tag.
