Re: Downloading files
Hello Sean,
This saves me from a lot of work.Tnanx. I just tried it and it works fine,
except for the case of of images. I guess for that case I have to use
ContentType(image/jpeg).

Try this:
// get the file extension
String fileName = formFile.getFileName();
// the mime type for this file
String mimeType = servlet.getServletContext().getMimeType(fileName);
// if we got one set it
if (null != mimeType) {
response.setContentType(mimeType);
}
// otherwise set a default
else {
response.setContentType(text/plain);
}
// otherwise output the file
ServletOutputStream os = response.getOutputStream();
os.write(formFile.getFileData());
return null;
Works for us ... This way you leave it up to the container to tell you
the mime type. You can also configure mime types in your web.xml
deployment descriptor file.

Hi Alexander,
This is what I did after searching the archieves. I'm a little bit
confused
with the mime type (shouldn't multipart/form-data work for every type
of
file? it doesn't work for .jsps). I think I have to search more on this
one.
Thanx for the reply,

Re: When i have three buttons that all can submit the same form...
Subject: Re: When i have three buttons that all can submit the same form...
From: Pim [EMAIL PROTECTED]
===
Changing the form's action is the solution we chose with the help of
javascript.
We created a function:
function go(whatAction) {
document.forms('skillForm').action=whatAction;
document.forms('skillForm').submit();
}
The button then looks like
td align=leftinput type=button onClick=go('/WebApp/formSearch,do')
value=bean:message key=button.search///td
The advantage is that you can use an actionforms for each action (validation
in the actionforms) and a perform method in the action which does his thing.
The disadvantage is that the in the form action some other things may occur.
For example when somebody doesn't use cookies, the session id is written in
the form action. So it comes down to good old string manipulation which is
always tricky.
The other thing you could do is making the action class more intelligent. In
the action class you could find out which action is called. Based on that
knowledge do your validation en seek a correct forward. This solution is
discussed in this group several times. Just seach for 'multiple' and you get
wat you want.

when i want to click Add(or Delete) to submit the form, i should change

Are there any method else to do that except using JavaScript in Struts

Multiple war files
Hi, I am working on this Enterprise application where we have to split the whole UI into multiple .war and .jar files. The .jar files shall contain all the Action and Form beans and the .war file shall contain all the JSPs and the respective struts-config.xml, web.xml files. I can see how to split the jar files so that I can arrange the Action and Form beans seperately. But I somehow cant seem to find a way to arrange the JSPs into different war files. I am using jsp templates all across the product and some of the components like the header, buttons, template page etc shall be common throughout. So my question is, can a struts-config file in a given war file access JSPs in another war file. I guess one way to do that by prepending a ../war file name to the jsp so that the Server knows where to look for that JSP. All I wanna know if this is possible and if there is any cleaner way of doing this. How does one usually organize the whole UI into multiple units so that some units can share some resources like templates and headers so that they dont have to be duplicated in each war file. Thanks. -Jitesh -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

problem with bean having session scope
Hi, I have 3 form beans. Each of them have a session scope defined in the struts-config.xml. Here's the config for one of them: action path=/piechart type=be.stluc.info.struts.PieChartAction name=piechartform scope=session When I try to access them in one of my Action class, I don't have any problem. But when I try to access them, from one other Action class, then suddenly, they don't exist anymore. I used the piece of code, Mr Keith Bacon posted in reply of one of my previous mail ( http://www.mail-archive.com/struts-user@jakarta.apache.org/msg25984.html ) And that so, I saw that one time, my session contains all three form beans and another time my session contains only one form bean. Here's the code I use in my Action classes: ParticipantDetailsForm partDetForm = (ParticipantDetailsForm) request.getSession().getAttribute(participantdetailsform); (participantdetailsform is one of the 3 form beans I share in the session) Could anyone give me pointers where I should look for ?

You can do it this way, but I would use a Struts tag instead of a jsp tag.

Now I use Forte for JAVA 4.0 EE Early Access Programm and now the application doesn't work anymore. When I try to start tomcat I alwazs get the error message that ActionMappings or ActionFormBeans collection cannot be found. I use jdk1.4 SE. I'm pretty sure there is no error in the struts-config.xml cause it worked before pretty good. It looks to me like the action - Servlet is not able to read the struts-config.xml or looks in the wrong place and not below WEB-INF ? Any tipe how to solve this problem ?

Re: Timestamp
You should download the latest nightly Struts build and use org.apache.struts.taglib.bean.format.sql.timestamp=dd/MM/ in your ApplicationResource.properties file.

Populating a FormBean's underlying value object
I have a situation where I want to have an ActionForm (let's say AutomobileForm) w/ only 1 variable (Automobile). If the Automobile class's get/set parameters were all run of the mill types (String, int, boolean, etc), I would normally just have a method called 'getAutomobileObject()' inside the ActionForm. Then from the JSP page I would just have something like 'html:text property=automobileObject.carType/' and then the Automobile object within the AutomobileForm would automatically be populated (I believe via the BeanUtils.populate() method). Now the problem I'm having is the get/set parameters of Automobile are not run of the mill data types, but rather very specialized custom classes. I saw from the Struts Javadocs that once you start running into anything specialized, you're going to have to implement a specialized means to provide for automatic bean population. From what I can see, I'd have to change the code within the BeanUtils.populate() method to do this.I'd rather not since it makes upgrading to newer versions of Struts more complicated.

Tranforming Collection to a Map
Subject: Tranforming Collection to a Map
From: Lance [EMAIL PROTECTED]
===
Is there a method somewhere hidden in the commons package for doing this. I
see the CollectionUtils.getCardinalityMap(Collection col) method, but it's
not what I'm really looking for. I wanna do something like this:
Collection roles = new ArrayList();
//populate list
Transformer tranformer = new RoleMapTransformer();
Map map = CollectionUtils.getMap(roles, transformer);
//My Transform class
class RoleMapTransformer implements
org.apache.commons.collections.Transformer
{
public Object transform(Object obj)
{
RoleData role = (RoleData)obj;
return new DefaultMapEntry(role.getRoleID(), role.getName());
}
}
Maybe org.apache.commons.collections.BeanMap does this. There's just not
enough info in javadocs

RE: Populating a FormBean's underlying value object
the servlet spec only provides Strings for received parameters, so you need to be able to convert from this. I use adapters to get this type oof conversion via struts. I wrap the real bean inside, and the population of the underlying bean is handled by the wrapper ( it's actually just parsing a double out, but with special formatting requirements ) this also means I can populate a business bean, that's not an ActionForm and get web specific formatting / error handling. I'd actually like to get struts to pass in the request to the population call -- which would obviously make BeanUtils population a bit more web specific (by allowing more syntax in the property field to pass well known objects), but would allow my wrapper to be completely stateless. -Original Message- From: john.corro Sent: 15 March 2002 15:13 To: struts-user Cc: john.corro Subject: Populating a FormBean's underlying value object I have a situation where I want to have an ActionForm (let's say AutomobileForm) w/ only 1 variable (Automobile).

Re: nested:iterate - set method not called
Thanks for the reply Arron, ... well appreciated.
but I noticed in your example that the MonkeyBean contains an ArrayList of
monkeys (ArrayList monkeyList) and you have both a setter and a getter
method for it. I was trying to duplicate this on my form bean. My
ArrayList is contained in the FormBean itself. That's why I was expecting
the setter method in the formbean to be called.
Also, is it necessary for the beans contained in my ArrayList to a reference
to the form, much like you have a reference to the BananasIncorporatedBean
from the MonkeyTeamBean.
I apologize if these are simple question, I've struggle with this for 2 days
now and the project deadline is not budging.

The getter will only ever be called, as it's the middle-man.
The system only wants to set the name property on the nested bean. It
will call the getter of the extrainfo object to get at the nested
bean, and then set its property. Never actually calling the setter of
the parent bean property.

Re: Help about iterate tag using
Check out the JSP™ Standard Tag Library (JSTL)
http://jakarta.apache.org/taglibs/doc/standard-doc/standard-beta1/Overview.html
snip from above page
The convention is to use the name var for any tag attribute that exports information
about the tag. For example, an iterator tag exposes the current item of the collection
it is iterating over in the following way:
c:forEach var=customer items=${customers}
...
/c:forEach

Re: Populating a FormBean's underlying value object
If I understand what you're saying, (using the previous Automobile example)
you would have something like
// THE ORIGINAL VALUE CLASS
public class Automobile
{
private CarType carType = null;
public CarType getCarType(){ return carType; }
public void setCarType(CarType ct){carType = ct; }
}
// THE WRAPPER CLASS
public class AutomobileWrapper
{
private Automobile auto = new AutoMobile();
public String getCarType(){ return CARTYPE CONVERTED TO
STRING; }
public void setCarType(String str){ auto.setCarType(CODE TO CONVERT
STRING TO CARTYPE); }
}
and then have the AutomobileWrapper class inside the ActionForm. Is this
correct? That's certainly one option I was considering too, but we're
looking to retrofit a current app to use Struts and theres hundreds of
classes like the Automobile classthus we'd have to write Wrapper classes
for most/all of those classes. Unless we absolutely have to, we'd prefer
avoiding that solution. I was originally hoping for something along the
lines of extending the BeanUtils class to accommodate additional data types,
but in a way that we don't have to alter the original source code to make
use of the extended BeanUtils class.

Hi, I noticed that this particular feature is on the Struts Project Wish-List, but I really need it now!! Well not really. I could revert back to my ugly scriptlets. But anyway, the problem is - I have an array of Strings (each representing a color - e.g. #33FFCC) and I'd like to present them in a table of radio buttons, so that the user can choose a color to represent something. I have begun by logic:iterating over the array. I'd like the value of each radio button to be the color (i.e. the current String from the array). It seems that there is no obvious support for something like this within the current API, so I'm just wondering if anyone has found a way!

I had a similar problem, but I am still using struts 1.0.2 release build so

logic:iterate id=entry name=searchresult scope=request type=foo
indexId=index
tr
tdinput name=cbx%=index.intValue()% type=checkbox
onclick=javascript:foobar('%=index.intValue()%');/td
tdbean:write name=entry property=foo filter=true//td
tdbean:write name=entry property=bar filter=true//td
/tr
/logic:iterate
/table
Maybe this is not the struts way of doing, but I at least it works...

unless the first checkbox is checked.
The original plan: call the function using (this) as a parameter, determine
the name of the form element that called the function using this.name, use
it to derive the name of the row's second checkbox, then set the second
checkbox's disabled property to false.
PROBLEM -- the only way I know of to alter the properties of a form element
identified by a string is to attach an id to the element and reference it
using document.all[variable_whose_value_is_the_id_of_the_element], as in,
document.all[elementId].disabled=false
where elementId is a variable whose value is the id of the element whose
property we want to set.
Except there doesn't seem to be any way to attach an id property to a
nested:checkbox tag... and DEFINITELY not a way to give it an id whose value
incorporates all the indexId values that are part of the current chain of
nested:iterate blocks (say, if it were buried 3 levels deep and would have a
corresponding name of first[3]second[6]current[9].propertyName).
BIGGER problem -- I'm not sure whether this affects references by variable
value rather than explicit name, but supposing for a moment the second
checkbox ends up getting named list[0].accepted, attempting to refer to it
directly by name within a javascript function as an experiment fails,
because the [x] part of the name gets interpreted by Javascript as an array
rather than as part of the name:
// crash and burn, because Javascript thinks we're referring to an array
named list
list[0].accepted.disabled = false;
Any suggestions on using nested:iterate, nested:checkbox, and the various
parameters available to come up with some scheme that will let me derive the
name of the row's other checkbox and access its disabled property?

RE: problem with bean having session scope
I suppose the form bean is created the first time I use a jsp:useBean tag in my jsp file, isn't it ? (for example: jsp:useBean id=searchbydateform scope=session class=be.stluc.info.struts.SearchByDateForm/) Actually, the creation of the ActionForm bean is handled by the Struts framework itself (I guess by the controller servlet?). That's how forms can be populated automatically via the Struts taglibs and then passed to the Action class associated with this particular ActionForm class. This is just a shot in the dark...but perhaps the explicit creation you are specifying by the jsp:useBean tag is screwing up Strut's management of the ActionForm bean? In any case, you don't need to use the jsp:useBean tag at all for ActionForm beans, as Struts takes care of instantiating, read/writes, and scope management for these beans. --joe -Original Message- From: Slimane Zouggari [mailto:[EMAIL PROTECTED]] Sent: Friday, March 15, 2002 9:15 AM To: Struts Users Mailing List Subject: Re: problem with bean having session scope Thanx, I supposed it was something like that :) The thing is, I still don't understand why my beans aren't shared among all of my action classes :( Friendly Regards, Slimane At 12:05 15/03/2002 -0500, you wrote: AFAIK, a session bean is destroyed when the session expires (30 min by default).

form bean roperties and ArrayLists
Can form bean properties be of type ArrayList?
And if yes, are there any special considerations when doing so, with
regards to the getter and setter methods?
I am using an ArrayList in a form bean as follows:
--- snip ---
...
private ArrayList recipients;
...
(in the constructor)
recipients = new ArrayList();
...
public void setRecipients(ArrayList recipients) {
this.recipients = recipients;
}
public ArrayList getRecipients() {
return this.recipients;
}
--- snip ---
I am getting the following error:
exception
javax.servlet.ServletException: BeanUtils.populate
...
root cause
java.lang.IllegalArgumentException: argument type mismatch
. and I suspect it has something to do with the ArrayList usage.

Holding on to request data
Hi - I need to keep a request around during a page display. What I am doing goes like this: - User clicks on a button - Request gets passed to various struts Action classes where various things happen - Request then gets passed to a jsp page. This jsp page is a frameset containing two frames. The second frame needs to refresh itself (I do this with a meta tag). This is basically an action in progress stage, where a status message is displayed in the lower frame. Once the action is done, the message gets replaced with actual data, and the auto refreshes stop. Problem is, once control goes back to the browser to display the jsp, the request is lost. Unfortunately, it contains data that needs to be passed back for the refresh action. Right now I am pulling out the individual parameters and attributes and building the URL for the refresh with them. This is ugly, since every time info is added to the request, it has to be manually added to the refresh URL. Is there an easy way to have the jsp page just pass the original request on to the refresh URL? I don't want to put the request info in session scope, since it is not really session information. One limitation - I can't use JavaScript here. One of the project requirements is no client-side code. Thanks, Bryan -- Bryan Glennon (mailto:[EMAIL PROTECTED]) BPG Consulting, Inc.

Re: form bean roperties and ArrayLists
Data coming from a browser that is used to populate a form bean is basically
of type String or String[]. I think if you change the ArrayList to a string
array you will have better luck. I haven't tried this yet but it has a
better chance of working than the ArrayList declaration.

Oddly enough, I was originally using String arrays but I decided to
change to ArrayList instead! Anyways, I found the solution to my
troubles, from the www.keyboardmonkey.com/struts sample application
(StrutMonkey.war, specifically in MonkeyTeamBean.java).
Here's what I did, in case anyone is interested. Quite a simple
solution actually.. I only had to change the getter and setter
methods:
-- snip--
public void setRecipients(Object[] newRecipients) {
recipients = new ArrayList();
for(int x=0; x newRecipients.length; x++) {
recipients.add(newRecipients[x]);
}
}
public Object[] getRecipients() {
return this.recipients.toArray();
}

RE: How do I change images (mouseover, mouseout) using the struts API
Since this is client-side UI behavior, you will need a Javascript handler function to swap out the images...once you have it (the function), use the onmouseover attribute of the html:link tag to specify the function that should be called. This is a pretty common piece of Javascript functionality, and you should have no problem finding an example on the web that can be tailored to your needs. The only way to do this without JavaScript is to refresh the whole page, and I'm pretty sure that's not what you want. :) -Original Message- From: Paul Idusogie [mailto:[EMAIL PROTECTED]] Sent: Friday, March 15, 2002 11:23 AM To: [EMAIL PROTECTED] Subject: How do I change images (mouseover, mouseout) using the struts API Importance: High Can someone kindly provide guidance on how to implement this using the taglibs available with struts?

Valid questions, all. :) I have to admit I'm not 100% sure when the ActionForm bean is first instantiated/initialized, but this is what I think: The ActionForm bean is created and initialized when the URI specified by the action-mapping for this particular Action/ActionForm pair is requested.

As for the last question, ActionForm beans can appear as fields inside other ActionForms, so you can nest your form beans such that when one gets instantiated, all of the nested form fields get instantiated too.

RE: problem with bean having session scope
Yep, that's what I meant, mis-type on my part there. hmmm...so you want 3 ActionForm beans to be instantiated when a single Action is delegated to, but don't want to use nested forms? Okay, you can do this two (maybe more) ways: 1. You could chain your actionforwards such that the Action called forwards to a second Action, the second Action forwards to a 3rd, etc., and thus your ActionForms get instantiated. The final Action in the chain then forwards to whatever page you wanted the user to see. 2. The Action (call it Action A) that is called when it's associated URI is requested explicitly creates whatever ActionForms you want and initializes them with setXXX methods. Then Action A places these form beans into the HTTPRequest object as attributes with the SAME NAME that struts would use for the attribute, i.e. the logical name specified in the action-mapping for the form bean. Then, when subsequent URI's are requested associated with other Actions, if Struts finds that an attribute with the associated (with the particular Action) form bean's logical name already exists, it will use that object rather than instantiating a new one (I'm pretty sure that's how it works). The only drawback is that you would have to make sure that Action A's URI is requested BEFORE the other Actions' URIs, so that your logic will initialize and store the ActionForm beans rather than the Struts framework. whew. I don't know if that helps, but it's the best I could come up with based on what I know about Struts. :) A final consideration: Is is possible that 2 of the 3 beans don't need to be ActionForm beans at all, but just value objects that are created and stored in the session? -Original Message- From: Slimane [mailto:[EMAIL PROTECTED]] Sent: Friday, March 15, 2002 3:49 PM To: Struts Users Mailing List Subject: RE: problem with bean having session scope Hi, Thanx again for your answer :) The problem is that I don't want to nest my ActionForm, I want them all treated as a unique session bean.

Iterate problem
Dear Friends, I have a jsp in where we have columns as follows Add no. of rows you wish to add - go AB CD E save 1. Using java scripts we allow user to add rows dynamically on the page. 2. How may I achieve this functionality of dynamically adding rows using struts? how will it map it back to an collection attribute in java bean. Everybody's comments are highly appreciated.

RE: problem with bean having session scope
okay, thanx a lot for your help :) I'll try the second method tomorrow (now it's 2am and I'm feeling sleepy :) Friendly Regards, Slimane At 17:02 15/03/2002 -0800, Someone poor demented soul by the name of Joseph Barefoot presented us with the following text which may contain useless information. Yep, that's what I meant, mis-type on my part there. hmmm...so you want 3 ActionForm beans to be instantiated when a single Action is delegated to, but don't want to use nested forms? Okay, you can do this two (maybe more) ways: 1. You could chain your actionforwards such that the Action called forwards to a second Action, the second Action forwards to a 3rd, etc., and thus your ActionForms get instantiated. The final Action in the chain then forwards to whatever page you wanted the user to see. 2. The Action (call it Action A) that is called when it's associated URI is requested explicitly creates whatever ActionForms you want and initializes them with setXXX methods. Then Action A places these form beans into the HTTPRequest object as attributes with the SAME NAME that struts would use for the attribute, i.e. the logical name specified in the action-mapping for the form bean. Then, when subsequent URI's are requested associated with other Actions, if Struts finds that an attribute with the associated (with the particular Action) form bean's logical name already exists, it will use that object rather than instantiating a new one (I'm pretty sure that's how it works). The only drawback is that you would have to make sure that Action A's URI is requested BEFORE the other Actions' URIs, so that your logic will initialize and store the ActionForm beans rather than the Struts framework. whew. I don't know if that helps, but it's the best I could come up with based on what I know about Struts. :) A final consideration: Is is possible that 2 of the 3 beans don't need to be ActionForm beans at all, but just value objects that are created and stored in the session? -Original Message- From: Slimane [mailto:[EMAIL PROTECTED]] Sent: Friday, March 15, 2002 3:49 PM To: Struts Users Mailing List Subject: RE: problem with bean having session scope Hi, Thanx again for your answer :) The problem is that I don't want to nest my ActionForm, I want them all treated as a unique session bean.

Link Tag w/ improved javascript/ecma support
Greetings, I don't know if a similar solution has been provided, but, I tweaked the Link Tag to support the writing of 'javascript:[function_name]([param1,param2,param3...])' to the href attribute of the final output. Here is a summarization of it's functionality: I added the following attributes: function - This is the name of the javascript function that will be called; functionName - This is the name of the bean that will provide parameter values from one of it's properties. functionProperty - This is a property of a bean that will either provide a String or an ArrayList to populate the parameters of the function urlIndex - This allows you to include the url generated by href,forward or page to be included at a specific place in the funcion's parameters. There is another class that I wrote that does the actual processing and preparation of the url. I named it EcmaUtil. I modeled the computeURL and computerParam methods of the RequestUtils class when I built the methods for the EcmaUtil. The LinkTag class that I wrote extends the BaseHandlerTag under the org.apache.struts.taglib.html package of struts jar. I know the code needs a bit of reworking to fit back in to the struts framework. I stripped out the MessageReources for the most part and removed some exception handling that will need to be included again. Anyways, if nobody has done this in the nightly or if it sounds like it might be of use. Let me know and I will post the code,the tld and an example of it's usage.

RE: How to Pre-fill a formbean - correction
Without seeing the source code to mainForm, we can't help much. It looks
like you don't have a method in mainForm with a signature like this:
public void setProperty1(String value) {
...
}

In mainAction, where form is passed in by the method header, the code
form.setProperty1(Dog);
compiles.
In loginAction, the code:
MainForm mainForm = new MainForm();
mainForm.setProperty1(Dog);

You can do it this way, but I would use a Struts tag instead
of a jsp tag.
Instead of using jsp:useBean and jsp:getProperty, all you
need to do is
bean:write name=mainForm property=mfProperty/
and that will write out the mfProperty to the JSP.

Phil,
Your loginAction should create and populate a mainForm
bean and then saves it in the request scope. In the
main.jsp, get a reference to this form by:
jsp:useBean name=mainForm scope=request
class=com.MainForm
and the input fields on that jsp get the defaults from
this form bean. You have to use class (not type) so
that if you come from a differene route to main.jsp
rather than Login and the mainform bean may not be
there already, a new one will be created for u. Then
your jsp won't bombs and the input fields still get
blank defaults.
