StrutsTestCase
Thanks to this list I just found the StrutsTestCase package. I think its a great tool. Testing my forms and actions OUTSIDE the container has increased my velocity 10 fold. But it seems that not many Struts people talk about this package (aside from page 510 of J.B.'s book). Is there something wrong with it? Seems to me that StrutsTestCase really allows you to do TDD and Struts, a very powerful combination. Am I missing some major negative about StrutsTestCase?

file upload problem
Hi,
I am modifying the upload files given by struts and trying to upload the
file to server without the user entering any path.
I have modified the upload.jsp with
html:text property=filePath value=/upload/images /
Its means I am trying to upload to the same context in which the jsp is
running (webapps/test/upload/images)
I have modified the UploadAction.java as
//else {
//write the file to the file specified
String filePath = theForm.getFilePath();
System.out.println(filePath:+filePath);
String fileName2 = filePath+/+fileName;
System.out.println(fileName2:+fileName2);
OutputStream bos = new FileOutputStream(fileName2);
int bytesRead = 0;
byte[] buffer = new byte[8192];
while ((bytesRead = stream.read(buffer, 0, 8192)) != -1)
{
bos.write(buffer, 0, bytesRead);
}
bos.close();
data = The file has been written to \ +
theForm.getFilePath() + \;
//}
I get this output too
filePath:/upload/images
fileName2:/upload/images/test.jpg
I do not have any error the page just becomes blank and the file is not
uploaded. Any ideas?

Re: Preview of an Image and text
1. From the jsp page select the image (image path) for uploading. Let the
preview button be a submit button .
form name =frm method=POST action=$link.setAction('graphics')
enctype=multipart/form-data
INPUT TYPE =hidden NAME =filePath size=39 value=C:\Program

Re: Displaying errors messages from validate in V1.2.4
Your ActionMessage should contain the key to a message in some message
resources, rather than the actual message itself. Something like...
errors.add(ActionErrors.GLOBAL_MESSAGE, new ActionMessage(
user.required ) );
then define user.required=User name is null in your message resources.

the problem is when i write my regex in validator.xml file as [A-Za-z0-9-.\\s]
its fine but as soon as i write [A-Za-z0-9-.\\s\u00E0] its not working
I even tried to replace \u00E0 with\x{E0}(hex) its still not working.
Please kindly help me out what should i do.(somewhere i read that old version
of validator framework supported this)

Works on IE, can't say whether it does on anything else. Of course,
this will only work if you have enough information to construct the
complete preview on the client at that point, but you could
alternatively submit the form, then in the reply construct the file://
reference to the image as I've done above. That would probably give you
the best of both worlds, and also remove any cross-browser concerns.
But, if you can do it without touching the server, so much the better I
figure.

Re: Preview of an Image and text
Just carry the path of the file, not the image itself. When you submit
the form you can get at that information (I believe, if not just grab it
via JavaScript on the form submission and stick it in a hidden field).
Then, when yout next JSP executes, you have the path to the file and you
construct the img path:
img src=%=file://+myForm.getPathToImageUserSelected()$
Something like that. The basic idea is that the JSP you send back as a
result of the form submission is displaying the image from the user's
PC, not your server. You just need to append the file:// part of the
image's URI at some point.

RE: Tiles controller
Jim,
I think I see your problem: The getDataSource() method is only available in
an Action, not in a Controller. You could mix the two and make your action
subclass a TilesAction. That would give you access to a merging of both
worlds: Action and Controller. For more details, you could read Tiles

bean:message and escaping
Hi is there any way to escape html with bean:message?. The only way I find to achieve this is: 1 - set a pageContext var with the bean:message value. 2 - use bean:write, wich escapes html. I'd like to do this with a single tag. Something like bean:message key=mykey filter=true / If it's not possible wich is the best practice? Thanks in advance.

returning to correct form after validating a page in a wizard form
Here's hoping somebody's still answering questions this close to Christmas
:)
I have a form that takes place over 3 pages, with prev and next buttons for
the user to navigate around with. The buttons call their own action in my
dispatchaction, which increments the page # and sends to the appropriate
page. Now that I'm at the end and have added in the validation for this
form, I realize that I may have made a wrong turn... since I can only supply
one input in my actionmapping and it really needs to be one of 3. So,
while it does a lovely job of validating, its always returning me to the
wrong form :(
What I'd really like to do is just hard-code the input from the code in my
action... Is that possible? Or do I need to go back to the drawing board?
Thanks for the help!

Re: returning to correct form after validating a page in a wizard form
I may not be understanding this, because it seems somewhat obvious... I
assume you can determine on which page of the wizard the validation
failed... Assuming that's true, simply don't return the input forward,
instead have three forwards in your /submission mapping, as it looks
like you do already, and return the appropriate forward.
I assume I'm missing something because that's too obvious...

Validation using multiple resource bundles
Validation of data in form fields worked fine when I had only default
resource bundle. But, when I started using multiple resource bundles,
the validation failed. I tried to specify the value for bundle attribute
for the 'arg' elements(s), and 'msg' elements but didn't work.
Following is my environment:
Struts 1.2.4
Tomcat 4.1.30
Commons Validator 1.1.3
Using http://jakarta.apache.org/commons/dtds/validator_1_1_3.dtd; in
validation.xml
As per the above DTD, we can specify the value for bundle attribute.
When searching on the internet for this problems, on some sites, I found
that Validation package doesn't support multiple resource bundles, but
only supports default resource bundles. Is that true? Or this was true
only with old versions of struts/validators.
Here is an example of my field element in validation.xml file:
form name=createUserForm
field
property=userId
depends=required,minlength,mask
arg position=0 bundle=security key=label.userId/
arg position=1 name=minlength
key=${var:minlength} resource=false /
var
var-nameminlength/var-name
var-value5/var-value
/var
msg name=mask key=userId.maskmsg
bundle=security /
var
var-namemask/var-name
var-value^[0-9a-zA-Z]*$/var-value
/var
/field
/form
Any help is greatly appreciated.
TIA

checkbox array transfer problem
I have the following problem with checkbox arrays. I would
really appreciate clues on what is the best workaround.
The situation is this:
- I have a data entry page flow with multiple pages
entering data into a form bean stored on the session
(all the actions share the same form bean).
- Several pages contain checkboxes so I have to reset
their corresponding form properties in an overridden
ActionForm.reset() method.
- Some of these checkboxes appear on the first page only
and causes a problem as the form will reset their
properties when navigating to the second page, but they
will not be repopulated as they don't have a control on
this page and therefore will remain cleared.
For simple checkboxes I just put a corresponding
html:hidden field on the pages that shouldn't render that
particular checkbox. The hidden field makes sure the
checkbox's value is posted through to the action and thus
repopulated into the form.
But, for array checkboxes created with html:multibox I
don't succeed with this solution. The solution with the
hidden field I used for simple checkboxes will only hold
one value, and thus will only keep one of potentially many
selections in the checkbox array.
How should this best be solved?
At the moment I have implemented a workaround that will only
reset the checkbox array when populating from a page that
actually contains the corresponding checkboxes. I do this by
adding a hidden flag field that signals that the page
contains the checkboxes and I can later use this as a
conditional in the reset method:
page1.jsp
input type=hidden name=hasPersonCheckboxes
c:forEach items=${personList} var=person
html:multibox property=personIds
c:out value=${person.id}/
/html:multibox
c:out value=${person.name}/
/c:forEach
MyActionForm.java:
public void reset(
ActionMapping mapping,
HttpServletRequest request)
{
if ( request.getParameter(hasPersonCheckboxes) != null )
personIds = new Long[0];
}
This way, if page2.jsp doesn't contain a hasPersonCheckboxes
field, the personIds attribute will not be cleared when
navigating to this page and will retain its value (given
that the form bean scope remains on the session).
But, there may be a better and cleaner solution?
(Sometimes I wish that Struts would include support for
handling all this checkbox reset stuff. F ex, each rendering
of Struts' checkbox or multibox tags could make additions to
some Struts managed hidden field that records what checkboxes
are placed in the form, and could use this for automagically
clearing the appropriate properties.)

Re: Struts and JDK 1.4.2_06
Mike Darretta a écrit : I encountered a strange issue that may be relevant to others After upgrading our JDK from 1.4.2_05 to 1.4.2_06, many of our struts actions reported the following error: Got the same problem when update tomcat and jdk (don't know which causes troubles). No getter method for property currentView of bean pagingListForm I upgraded all our apache-related jars to the most recent releases, but to no help. Then, I had an epiphany and simply renamed the form bean property to currView vice currentView, along with its accessor. Suddenly, everything worked as before (hmm...). For my case, my propertie was a calculated one (read-only) with only a getter method. (and the error message was the same No getter method ...) I must have to add a setter (empty code) and a variable to fix the bug. Are there any thoughts on how a form bean property name could conflict with a JDK release?

Re: Page navigation links
Is the Action path include the parameter I pass in the request ? For an example: Form A to B, I will pass code='Bcode' in Action B Form B to C, I will pass code='Ccode' in Action C If I back Form C to B, I need to pass code='Bcode' The Question is Is the Action path will include this 'Bcode' If not I need to think the other way to get it back. Thanks a lot Cliff --- In [EMAIL PROTECTED], [EMAIL PROTECTED] wrote: Presumably you would want such a construct to work regardless of what path a user took to get to a specific page (assuming there ARE multiple paths in your app, maybe there aren't). So, if it was me, I'd be thinking a linked list stored in session. Each page that is presented would append itself to the list. Clicking a link would have to break the list at the point of the page that was clicked (i.e., if there are six pages in the nav trail and the user clicks the third, you basically want to discard the last three, which just means removing the link to the next element from the element of the page the user clicked). You would of course have to add enough information to each element in the list as to allow your app to go to that page when clicked. Might just be storing the Action path, might mean each element is really a HashMap with a bunch of information, you would have to decide. I'm not sure something like this exists yet, I'd certainly think it does though.

validation issues when using multiple modules
I have configured two modules in my web application using Struts 1.2. Each has its own struts config as defined in the web application's web.xml. Each has its own validation XML and resource bundles as defined in their respective struts config files. The problem I'm seeing is that if I violate a validation rule for the root module (/), everything works as expected and I see the appropriate error message on the page. However, if I violate a validation rule in the sub module (/app2), the validation works fine except the error message prints out without the value that should be filled in by the arg0 element for that field. In other words, instead of 'List size is required' I see 'is required', where 'List size' is the value for key 'list.size' that is defined in the resource bundle for module /app2 and is referenced by the arg0 element for the list size field. I am referencing the resource bundle for /app2 in the html:errors tag. In addition, I have tried defining list.size in the root module's resource bundle just to verify that the problem isn't that struts is looking there for it, and that doesn't seem to be the problem because I still see the same behavior. Has anyone seen anything like this or can anyone give me some hints as to what might be going wrong here?

Re: exception thrown while trying to validate user input
What version of struts are you using! I think that the version you are using might be de reason for this problem. ActionErrors has been deprecated in favor of ActionMessages as far as I know in recent struts versions. On the other hand, struts in action covers afaik version 1.1. Hope this help.

Re: Dynamically adding an ActionMapping
On Thu, 16 Dec 2004 11:21:01 -0500, Chaikin, Yaakov Y. [EMAIL PROTECTED] wrote: Craig, What is the reason the configuration gets frozen? I don't mean to ask about the mechanics of how it's frozen. I am just curious as to why freeze it and not let it be dynamically updated during application lifetime? The primary reason for this approach is a performance-related optimization. Underlying most of the collections of configuration objects in Struts are uses of HashMap, which is explicitly declared to be non-thread-safe for methods that modify the structure, but thread-safe for read-only use. If one *knows* that the collection will never be modified during its lifetime, then one can also know that no locks are needed at read time -- and that happens a *lot* during the lifetime of a Struts-based application. On the other hand, if the configuration data structures were allowed to change dynamically during the lifetime of the application, we'd have to lock on read accesses as well. That doesn't matter in an app with, say, 10-20 users who play with it occasionally -- it is critically important in apps that are supposed to be Internet scale. A completely separate discussion could be had about the maintainability and testability of an application that allows dynamic updates to its configuration. I'm very much in the conservative camp on this issue -- if you haven't been able to thoroughly test the exact application environment of your updated code (and this is basically impossible when you allow dynamic updates to the runtime configuration), then you have *zero* guarantees about the quality of the implementation of your app at any given time.

Re: OJB struts
More importantly (from the perspective of Struts) is that the webapp framework should not *dictate* a decision for how you factor your business logic and persistence logic. That is a decision that should be made on it's own merits (independently of how you choose your view tier framework) -- any solution that binds you to *one* particular view tier technology and *one* specific business logic technology and *one* specific persistence technology should be viewed with suspicion. Struts doesn't do that. Craig - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: file upload problem
Hi Jay,
I tried this way too, but I am actually getting FileNotFoundException. This
is the modified code
String filePath = theForm.getFilePath();
System.out.println(filePath:+filePath);
String fileName2 = filePath+fileName;
System.out.println(fileName2:+fileName2);
//byte[] fileContent =file.getFileData();
OutputStream bos = new FileOutputStream(new File(fileName2));
int bytesRead = 0;
byte[] buffer = new byte[8192];
while ((bytesRead = stream.read(buffer, 0, 8192)) != -1) {
bos.write(buffer, 0, bytesRead);
}
bos.close();
In the catch block I made SOP to print the exception and this is the output
in Tomcat console.
filePath:/upload/images/
fileName2:/upload/images/test.jpg
fnfejava.io.FileNotFoundException: \upload\images\test.jpg (The system
cannot
find the path specified)
Why is the system not able to find out the path?

Re: file upload problem
how is ur file path given ??/
please try to give the full path ie like C:\Program Files\Tomcat
5.0\webapps\cevm\uploadedimages\
ie filePath value should be C:\Program Files\Tomcat
5.0\webapps\cevm\uploadedimages\
ie in your jsp page give something as below .
INPUT TYPE =hidden NAME =filePath size=39 value=C:\Program
Files\Tomcat 5.0\webapps\cevm\uploadedimages\/

RE: file upload problem
Hi Jay,
It works if I give in this way but I wanted to upload by giving relative
path. i.e. the context in which the application is working. Also if I print
File fileTemp = new File(fileName2);
System.out.println(fileTemp:
+fileTemp.getAbsolutePath());
I get fileTemp: D:\upload\images\test.jpg which actually doesn't exist. Any
ideas on how to over come this issue?
