ActionMessages with redirect
Hi all, Just before creating an ActioForward in my Action class, i am storing some messages using SaveErrors(). And I am using ActionForward(String path, boolean redirect) for creating the ActionForward with 'true' value for redirect parameter. My question is by doing this can I display the ActionMessages that I have saved using SaveErrors()? If not then how can I save ActionMessages/ActionErrors so that they are visible to me even after making a redirect? any suggestions? --RahulJoshi
How to remove the unwanted ???en_US string from ActionMessages
Hello all,
I am facing a wierd problem in my application. I want to add an
ActionMessage in the ACTION (LoginAction) class and then display the
message in the JSP page. In the JSP page, the messages are found without a
problem (so my ApplicationResources.properties configuration is fine),
however while prinintg them, the string ???en_US and ??? gets attached
to my message before and after respectively.
???en_US.my-message???
How do I get rid of these strings???
I searched the discussion-list for similar problems/solutions and found
this thread:
http://www.mail-archive.com/user@struts.apache.org/msg27565.html
However, the solution in that threads talks about using the presentation
logic as follows:
html:messages id=errmsgs
libean:write name=errmsgs//li
/html:messages
But thats exactly how I am doing also. But for me it still gives the error.
Below is the configuration and code snippets that I am using:
In struts-config,xml
message-resources parameter=myApp.ApplicationResources null=false/
In LoginAction.java
if (username == null || username.trim().length() == 0){
ActionMessages messages = new ActionMessages();
ActionMessage message = new ActionMessage(Username/Password cannot
be empty);
messages.add(credentials.empty, message);
saveMessages(request,messages);
In the JSP page
html:messages id=message message=true
div class=success
bean:write name=message/br
/divbr/
/html:messages
The output I get is
???en_US.Username/Password cannot be empty???

Re: How to remove the unwanted ???en_US string from ActionMessages
Hi there,
try this:
if (username == null || username.trim().length() == 0){
ActionMessages messages = new ActionMessages();
ActionMessage message = new ActionMessage(credentials.empty);
messages.add(ActioneMessages.GLOBAL_ERROR, message);
saveMessages(request,messages);
}
Basically, the thing to note here that ActionMessage takes a key from the
resource file which I assumed credentails.empty is. The first parameter of
the ActionMessges.add(...) is the property against which error is being
stored or the generic global_error constant.

Re: Struts action servlet mapping, getPathInfo() returns null
Again, thank you very much Laurie. I couldn't understand how ** wildcard mapping could work with suffix mapping (*.do). I have tried, in web.xml, *.do/** but tomcat said invalid url-pattern. If I manage to get ** wilcard mapping work with *.do, I will be able to correctly process a request like http://localhost:8080/myapp/server.do/chapter1/1.html Also, I've tried *.do** , tomcat did accept this but this time, it expected me to write ** at the end of all URL's. That is, it didn't work as a wildcard mapping. And in struts-config.xml, I modified my action as action path=/server** ... but this didn't work either. It seems that ** wildcard mapping is not possible with *.do suffix mapping. What do you think Laurie? -- Forwarded message -- From: Laurie Harper [EMAIL PROTECTED] To: user@struts.apache.org Date: Mon, 26 Sep 2005 14:31:10 -0400 Subject: Re: user Digest 25 Sep 2005 21:39:29 - Issue 6130 emre akbas wrote: Now, I have another problem. We have written our Struts application using prefix mappings, i.e *.do. In order to use DownloadAction with ** mapping, we should migrate to suffix mapping, i.e. /do/* . Is there an easy way of migrating a whole Struts application from prefix mapping to suffix mapping? Or, is it possible that both mappings exists in web.xml ? (Sorry, if these are weird questions.) [Note: '*.do' is a suffix, /do/* is a prefix (pre- - previous); just to reduce any confusion for people following along ;-)] Actually, I think wildcard mappings *should* work with suffix mapping too, though I've never tried it. But you can define both types of mapping in web.xml, so long as you pick a prefix your application doesn't already use. In other words, as long as you don't already have linkes that start /do/... then adding a /do/* mapping is fine. Migrating your whole app from one mapping style to the other wouldn't be super hard -- just find anywhere you have an explicit .do and update appropriately. However, I wouldn't recommend trying that if this is the only driver. If what you have works, keep it ;-) L.

Re: The mailreader example, database access
Some parts of the MailReader are well designed. Others not so much. Quoting from the Struts 1.2 documentation: * http://struts.apache.org/userGuide/building_controller.html The MailReader example application included with Struts stretches [the MVC] design principle somewhat, because the business logic itself is embedded in the Action classes. This should be considered something of a bug in the design of the example, rather than an intrinsic feature of the Struts architecture, or an approach to be emulated. In order to demonstrate, in simple terms, the different ways Struts can be used, the MailReader application does not always follow best practices. A goal for Struts Classic 1.3.x is to make the MailReader a true best-practices example with multiple plugins for the data access layer. We've taken the first steps toward that here: * http://opensource2.atlassian.com/confluence/oss/display/STRUTS/MailReader To offset streamlining the MailReader, we're adding a Struts Cookbook application with coding examples outside the scope of MailReader, based on the one Steve Raeburn started here: * http://www.ninsky.com/struts/ -- HTH, Ted. http://www.husted.com/poe/ On 9/22/05, Koen Jans [EMAIL PROTECTED] wrote: The struts design guidelines states that Actions perform the processing required to deal with a request (such as saving a row into a database); this can be done by logic code embedded within the Action class itself, BUT should generally be performed by calling an appropriate method of a business logic bean. Now, in the example, the database is retrieved from the servletcontext (why is this? one instance per user?) and the Action classes itselves perform the database operations on the database directly. This seems to me like poor reuseability.. Suppose i want to create a business logic bean, let's say UserHandler, wich handles all the user savings and retrievings. So in the Action class, i create an instance of UserHandler and let the UserHandler perform all the work. If i want to do this, i should pass the database along to a method, ex. userHandler.saveUser(UserDatabase database, String userName, String email, ..) But then i have to pass the database along, losing transparacy.. Or would this not make any sense at all? thanx - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: How to remove the unwanted ???en_US string from ActionMessages
Hi Amin,
Writting this:
ActionMessage message = new ActionMessage(Username/Password cannot
be empty);
will not solve the problem.
What you need to do to get rid of the following:
???en_US.Username/Password cannot be empty???
is:
1) Add a key/value pair to your application.properties file:
key1=Username/Password cannot be empty
2) You need to change the construction of your ActionMessage:
ActionMessage message = new ActionMessage(key1);
This will solve you problem.
Good luck.

ActionMessage and bundle choice
Hi, We know that ActionMessage class has a field to store the key of the message but not the bundle name of the key. For (error) messages that are not in the default message-resources, we can do the trick in the jsp file by giving the bundle of the key like: html:messages bundle=core id=msg bean:write name=msg/ /html:messages So far so good. But, what we shall do if the ActionMessages contain messages which have to be resolved from different bundles? Should we write several html:messages tags with different bundles?
Re: How to remove the unwanted ???en_US string from ActionMessages
when you construct your ActionMessage
the first parameter is the key into the MessageResource..
the second parameter is the resource OR string literal you wish to supply
assuming
message-resource parameter=classname [null=true|false] [key=name]
html lang=en
in this case if resource is true then your app will reference the key value
(name) located within
$webapp_home/classes/com/OrganisationName/app_en.properties

Help needed urgent
Hi all,
I am trying to list some names (with and ID code) and I want for each
name listed create a link, then when the user clicks on the link I want
to edit the record (the bean).
With this I have my list there with all the names:
http://localhost:8080/ExemploStruts/ListagemClientes.do
The problem is when I click on the name/link and it should call an
action in my DispatchAction, but it gives me an error on the server:
HTTP Status 404 - /CadastroClienteDispatchAction.do
*type* Status report
*message* _/CadastroClienteDispatchAction.do_
*description* _The requested resource
(/CadastroClienteDispatchAction.do) is not available._
Apache Tomcat/5.5.8
For listing the names I am using an this Action, which is
org.apache.struts.action.ActionForm type:
action path=/ListagemClientes
type=br.com.manager.action.ListagemClientesAction
forward path=/pages/dadosCliente.jsp name=sucesso /
forward path=/pages/erros.jsp name=falha /
/action
For my CRUD operations I am using an action of type
org.apache.struts.actions.DispatchAction:
action input=/pages/cadastroCliente.jsp name=ClienteForm
parameter=acao path=/CadastroClienteDispatchAction
scope=session
type=br.com.manager.action.ClienteDispatchAction
forward name=retorno path=/pages/cadastroCliente.jsp /
forward name=sucesso path=/pages/dadosCliente.jsp /
forward name=falha path=/pages/erros.jsp /
/action
This is my .JSP where I create the links:
logic:notEmpty name=listagem
logic:iterate name=listagem id=lista
tr
td bgcolor=#E6E8FAa
href=/CadastroClienteDispatchAction.do?acao=editarcodigo=bean:write
name='lista' property='codigo'/
bean:write name=lista property=nome //a/td
td bgcolor=#E6E8FA width=4% align=centera
href=/CadastroClienteDispatchAction.do?acao=excluircodigo=bean:write
name='lista' property='codigo'/
img src=imagens/lixo.gif border=0/a/td
/tr
/logic:iterate
/logic:notEmpty
These are my 2 action in the DispatchAction (excluir=delete, editar=edit) :
public ActionForward excluir(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
ActionErrors erros = new ActionErrors();
ActionForward forward = null;
ClienteDAO cadastroDAO = new ClienteDAO(this.getConnection());
ClienteFormBean clienteForm = (ClienteFormBean) form;
try {
cadastroDAO.delete(clienteForm);
forward = mapping.findForward(sucesso);
} catch (SQLException e) {
erros.add(ActionErrors.GLOBAL_ERROR, new
ActionError(errors.persistirCadastro, new String[] { e.getMessage() }));
forward = mapping.findForward(falha);
} catch (Exception e) {
erros.add(ActionErrors.GLOBAL_ERROR, new
ActionError(errors.persistirCadastro, new String[] { e.getMessage() }));
forward = mapping.findForward(falha);
}
if (!erros.isEmpty()) {
saveErrors(request, erros);
}
return forward;
}
public ActionForward editar(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
ActionErrors erros = new ActionErrors();
ClienteDAO cadastroDAO = new ClienteDAO(this.getConnection());
ClienteFormBean clienteForm = (ClienteFormBean)form;
try {
clienteForm = cadastroDAO.getDadosCliente(
((ClienteFormBean)form).getCodigo() );
clienteForm.setAcao(editando);
} catch (SQLException e) {
erros.add(ActionErrors.GLOBAL_ERROR,new
ActionError(errors.recuperarCadastro));
mapping.findForward(falha);
}
return mapping.findForward(sucesso);
}
Please, could someone tell me what is wrong OR tell me another way to
implement such thing.
I am using Struts 1.1
Thanks a lot
PS. My Bean and my DAO are working ok.

how to retain prepopulated values in ActionForm
Hi all, I need to show some prefilled value in a html form then take new inputs from the user and save the changes. I am doing this by prepopulating an ActionForm, putting it into request as an Attribute then displaying it onto the jsp. Its working fine and the changed value are also available in next Action. But the problem arises when some error is returned by ActionForm.validate() method In this case the same jsp is shown but the prepopulated values are gone. Is there any way to keep the prepopulated values in the jsp when input jsp is shown due to ActionErrors returned by validate() method. Do I need to store the prepopulated ActionForm in session instead of request? --RahulJoshi

How to reference pages external to a webapp using Tiles
I am working on an export coltrol system for the swedish customs. We are using struts and the tiles framework. We would like to have a separate webapp (or even a plain html site) with some standard templates for mainly menus. I have placed some images and standardized jsp-files there, these files should be used for all webapps developed. The problem is when I try to reference those jsp-pages in my tiles definitions file as absolute urls, Cannot get request dispatcher for path http://localhost:7001/std/tiles/common/layout.jsp. The referencing webapp is at http://localhost:7001/ex/do/... And the def looks like: definition name=.layout.ecs path=http://localhost:7001/std/tiles/common/layout.jsp; Is there a solution to this or must the standardized pages included in each webapp?

Re: how to retain prepopulated values in ActionForm
When a validation error occurs, the usual intention is to allow the user to correct his/her mistakes by presenting the values that were entered. If you wish to override this behavior, you can manually call validate() by applying some of the techniques Rick Reumann demonstrates in the section Manually call validate and use Request Scope on http://www.reumann.net/struts/articles/request_lists.jsp.

Re: how to retain prepopulated values in ActionForm
If the form is returned after validation, the fields should be refilled with whatever the user submitted, unless your input somehow causes a new request to be created. After validation, Struts has done exactly what you did to prefill the form: instantiate a form bean, populate properties, and place it into request or session scope under the name associated with the validating action mapping. Is your input somehow causing a new request to be created? This might lead to the values being forgotten. (A quick test of that might be to switch the scope of the validating action mapping to session, at least to see what happens.) Sometimes there are other components of a form (like a select menu) which are prepared by a prepopulation action but which are not properly form properties, and those don't automatically get re-established in a case like this -- is that what's happening to you? There are a few solutions for that, but rather than clutter this message, lets see if that is the issue or if I'm misunderstanding you.

I've seen this conversation before so I don't think I am saying anything

There is a performance overhead from reading a database to present to the

Re: using html:option tag
From: [EMAIL PROTECTED] This works fine and I can save the correct value to the database. The question I have is how do I display the same option tag when updating the user and the details are returned from a database. The same JSP snippet you posted should work in both the 'add' and 'edit' forms. For select list contents that are the same for every user, I use a ServletContextListener to place collections in application scope, and then use html:options or html:optionsCollection.

[RT Expr] HTH, Glenn [EMAIL PROTECTED] 27/09/2005 12:08 PM Please respond to Struts Users Mailing List user@struts.apache.org To user@struts.apache.org cc Subject using html:option tag Hi All, I am using the html option tag embedded within the html select tag to select a value from a drop down list as follows: html:select property=title html:option value=MrMr/html:option html:option value=MrsMrs/html:option /html:select This works fine and I can save the correct value to the database. The question I have is how do I display the same option tag when updating the user and the details are returned from a database. So in plain English after the user has saved the client to the db he then wants to update the record. A search is done but how do I display on the JSP page the selected option with the option of seleting something else from the drop down list. Thanks in advance
Re: CactusStrutsTestCase working problem with tiles extension
Thank you Richard for the answering... Since my app is written in a lower J2EE
version so I have to use strutstest_2.0.0.jar which doesn't support
verifyTilesForward() method.
Any other suggestions? Thanks.

Carl,
Check the CactusStrutsTestCase javadoc. You should use
verifyTilesForward instead of verifyForward(). There is also a
verifyInputTilesForward() too.

Re: writing images from a database
From: Braun, James F [EMAIL PROTECTED] Goal: Read a blob image from an Oracle database and render it on an html page using the struts framework. I have no trouble getting the image from the database. However, I wonder if there isn't a better way to display it rather than writing it to a physical file and then rendering it. I'm using the html:img tag to display the image now. When the browser encounters an img tag, it makes a separate request to the server for the image. You can map that request to whatever you want-- I would use a Servlet-- and write the bytes of the image out to the browser. I do this with JFreeChart to display a pie chart, but the basics are the same whether you read the image from a database or create it on the fly. If you want to use an Action, (maybe you need some values from the form bean to figure out what image to load,) you can 'take over' the response, and then return null from the execute method to tell the framework that it doesn't need to do anything else with the response. For images that don't change, there should be some sort of caching mechanism in place so you're not constantly going back to the database for the same image. -- Wendy Smoak - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: writing images from a database
You need to put in a bit more buffering, etc. in this code, Mark. I
recommend you read up on how to read and to write to files more
efficiently. Also, due to the nature of how computers work, I would
highly recommend you create a multi-threaded application to do this.
You will find that your performance will be hugely impacted.

There is a performance overhead from reading a database to present to the
JSP page, however you look at it. There is nothing wrong with writing the
image once to the file system, and storing a reference to the image on the
file system.

Re: writing images from a database
The Wiki is your friend:
http://wiki.apache.org/struts/StrutsFileDownload
Specifically, you will be interested in the downloadapp.zip sample I
posted there... it has an example of serving a BLOB from a database. All
you need to do is have a mapping to this Action, and use it as the src
attribute of an img tag.
As another poster said though, there is definitely a fair amount of
overhead to doing this. That being said, I've done it to good effect on
at least two occassions. But, you do have to think about whether it is
appropriate... in my case, it was a client's logo in a frame that only
changed when the user changed clients, very infrequent. I can't imagine
I'd serve images from a database if it was going to be needed a lot... I'd
have to have an exceptionally good reason for doing it. Maybe you do :)
In any case, that sample app should show you how.
Note too that even if you aren't using a version of Struts with the
DownloadAction, what's there is still somewhat applicable, and there's
nothing to stop you from bringing DownloadAction over to your app anyway
AFAIK.

iPlanet 6 and Struts 1.2
Platform: iPlante 6.0 (sp2 on Solaris, sp1 on Windows for dev) JVM: 1.2 Struts: 1.2 IDE: IntelliJ 5 I have structs running, but some things don't seem to work (like the JSTL support), but a more important break is the reading of the message properties file. In my struts config I have the following entry: message-resources parameter=com.wh.downy.resources.MessageResources null=false / At the moment, this resource contains the following (actually two copies, one just .properties and the other named _en_US.properties): errors.header=divul errors.footer=/ul/div errors.prefix=li errors.suffix=/li prompt.email=Your e-mails do not match. ppi_form.firstName=Please give your first name. IntelliJ properly sees them as a bundled resource and both show up inthe class path under /WEB-INF/classes under the app space on the server. But when I use html:errors / in a JSP, errors appear one after another and not in a ul. Further, if I try to use a message in a validator, I just get ??message_name_en_US???.

Of course a dirty way would be printing out plain html like input

Yes, you could do that. Another possibility would be to write a JSP 2.0
tag file containing something like
c:choose
c:when test=${type eq 'text'}
html-el:text property=${property} ...
/c:when
c:when test=${type eq '...

tag:mytag type=${obj.value.type}
property=${obj.value.content} ...
It's cumbersome (and there are some caveats about calling the HTML tags
from a tag file if you want to support optional attributes, which I can
describe if you're interested).
The other way would be write a traditional custom tag in Java and have
it call into the existing HTML tags to do its work.

Re: writing images from a database
The way I do this is to dynamically control caching on the CLIENT.
Some clients have one cache time and others have a different time.
Also, for different images, you can use different caching times on the
same client. There are lots of ways to fry this fish.

Re: Struts action servlet mapping, getPathInfo() returns null
Remember that servlet mapping and action paths are two entirely seperate things. For servlet mappings, *.do/** would be infix, not suffix -- and infix is not allowed. Suffix means, roughly, 'at the end'. In other words, you can either have 'text*' (prefix mapping) or '*text' (suffix mapping). It's one or the other, you can't mix them. So, to use wildcard action paths with suffix mapping, your mapping would be '*.do', your action would be specified like this action path=/my/action/** ... and the URL you would use to access it would look like this http://host/app/my/action/some/path.do The servlet contain matches the entire request URL against your servlet mappings, do it can't match '.../...do/...' because the '.do' is neither at the start of the URL (for prefix mapping) or the end of the URL (for suffix mapping). It's only *after* the contain matches the URL as a whole that it's passed to Struts for matching against your action paths. So, you either use prefix mapping and have something to match at the start of the URL, or you use suffix mapping and have something to match at the end of the URL. Like I said, I haven't tried it with suffix mapping, but that's how it would look in theory. L. emre akbas wrote: Again, thank you very much Laurie. I couldn't understand how ** wildcard mapping could work with suffix mapping (*.do). I have tried, in web.xml, *.do/** but tomcat said invalid url-pattern.

Is there an easy way of migrating a whole Struts application from prefix mapping to suffix mapping? Or, is it possible that both mappings exists in web.xml ? (Sorry, if these are weird questions.) [Note: '*.do' is a suffix, /do/* is a prefix (pre- - previous); just to reduce any confusion for people following along ;-)] Actually, I think wildcard mappings *should* work with suffix mapping too, though I've never tried it. But you can define both types of mapping in web.xml, so long as you pick a prefix your application doesn't already use. In other words, as long as you don't already have linkes that start /do/... then adding a /do/* mapping is fine. Migrating your whole app from one mapping style to the other wouldn't be super hard -- just find anywhere you have an explicit .do and update appropriately.

Re: JSF or Struts Classic (was Vs)
There is a fundamental problem with talking about the definition of
words in other than a lexical sense. Words do not have definitions
like you find, for example, in biology but, rather, have meanings and
the meaning is, as Ludwig Wittgenstein loved to say, the use.
People who look for and talk too much about definitions of terms
tend to have idiosyncratic and private senses of terms which leads to
confusion rather than to clarification, to heat rather than to light.
Words are neither swords nor shields in life and its battles, but are
a mysterious and wonderful public way to communicate within the
dimensions of our environments and understanding. Hence, there is not
a right or wrong way to talk about components, but there is the way
they are talked about and if you don't to do it that way, then no one
will understand you. I like the way Ted tackled this issue. The
issue never had anything to do with meanings, definitions or the word
component. Thanks, Ted.

If you are going to compose an application
from components, then the components are more closely aligned with the
business objects they encapsulate. A Customer component then may be
composed into any number of Applications from Accounts Payable to CRM. Such
a Component would have its own UI for CRUD operations, and a Web Services
Interface for data and method access, and it would likely have its own data
persistence or utilize framework or container managed persistence.
In our application, now that we are collecting coherent segments of
ASPX code into controls, that's what exactly what is happening. The
architecture is chain-based and service-orientated. We aren't using
business objects per se, but there are a number of business entities
present in the model (database schema).
The command and query files for Chain and iBATIS are grouped by
business entity. The iBATIS datamaps acts like a code-behind for the
Commands. For every coherent set of command, we end up with a
companion datamap configuration.
The ASPX page flows tend to follow entity lines as well, which became
even more apparent when we started normalizing the UI into controls.
Now we have a components like a FacilityFinder, FacilityLister,
FacilityViewer, and FacilityEdtior, each of which is encapsulated as a
tag (or component) with it's own markup and code-behind.
The neat part is that its easy to reuse these components when use
cases cross entity lines. If we need to list or edit facilities as
part of a larger case, we can plop the appropriate tag on the page,
turning it on and off as needed. The ASPX page then starts to act like
a controller. Instead of presenting content, it manages a set of
components from its own code-behind. Right now, most of our pages look
like this:
%@ Page language=c# Codebehind=Events.aspx.cs

(The content tags are part of the Spring templating system, which is
not unlike Tiles.)
This page presents a finder control and a lister control. The finder
control collects search criteria. The code-behind hands the critieria
it collects to the lister using a method like this:
protected void finder_Click(object sender, EventArgs e)
{
AppArgs a = e as AppArgs;
lister.Open(a.Criteria); // A Criteria is a Map
lister.Visible = true;
Template_Load(App.msg_EVENTS_HEADING,
App.msg_EVENTS_LIST_PROMPT);
}
After browsing the list, the client might select an item
protected void lister_Click(object sender, EventArgs e)
{
AppArgs a = e as AppArgs;
Key = a.facility_issue_key;
SetResult(App.RESULT_STEP_LIST);
}
SetResult is a Spring.Web base method. It fires a redirect or forward
to another page. We coded the result so that the Key property is
included. The reference is kept in a configuration file.
This ResultSet elements tells Spring.Web to redirect to the
Search.aspx page and append the query string op=Issuesq=${Key},
where Key is a property on the calling page. (Obviously, the value of
Key replaces the variable notation.)

Re: writing images from a database
I went through the process recently - the performance of MySQL handling images
was
soo bad I immediately changed all my thinking and put the images in a
sub-directory in
my file system.
The code I was using was buffering (32k) and the images were only about 100k
and still
I had to wait 8 seconds for them to appear on my browser - simply not
accepable. The
same images in the file system appeared near-instantaneously on my browser.
Also, MySQL had a default buffer size limit of 1mb, any file I uploaded needed
to be
within this limit. I know I can modify this, but what do I modify it to?
Should I make it
2mb, 10mb, 100mb, 2gb, 4gb, how big is my upload file going to be? It was all
very
restrictive and badly implemented. Maybe oracle is better?
Kind regards

I had to wait 8 seconds for them to appear on my browser - simply not
accepable. The
same images in the file system appeared near-instantaneously on my browser.
Also, MySQL had a default buffer size limit of 1mb, any file I uploaded
needed to be
within this limit. I know I can modify this, but what do I modify it to?
Should I make it
2mb, 10mb, 100mb, 2gb, 4gb, how big is my upload file going to be? It was
all very
restrictive and badly implemented. Maybe oracle is better?
Kind regards

There is a performance overhead from reading a database to present to

Two years, solutione exists, works, but is not accepted by the Party. Martin Cooper, 2005-06-17: It does have to do with the HTML 4.01 spec. With such a change, we allow the Struts tags to generate HTML that is not compliant with that spec. For *years* we have said that the Struts tags will generate valid HTML 4.01 code, and I, for one, am not willing to see us go back on that decision now. Whoa! Being a bit stalinistic, are we? What happened to freedom of choice? So un-American ;-) Craig McClanahan, 2005-06-21: As for adding something like html:attribute, I think it is definitely bad policy to hand developers a loaded gun aimed at their feet. They already have boxes full of TNT on their desks. Letting them have a gun as well does not change a lot. Really, imagine a battle tank with a gun which cannot be rotated backwards: We do not want them to fire at our own troops. Tank commanders are not idiots (en masse), so are programmers. I never took the best thing since sliced bread seriously, but seems that there are quite a few of Darwin Law victims, who can cut themselves with a kitchen knife and then bleed to death.

I'm using DB2 with pictures stored as blobs. We have a system similar
to what Wendy suggested. When the image is retrieved from the database
it is sent to an image servlet that will cache the image. The browser
then asks the image servlet for the image. The image servlet is also
smart enough to ask the database for the image if it finds it is not
available in the cache. I tried to write it flexibly enough so that the
size of the image cache and the the amount of time an image stays in
cache is flexible. Also, if this system becomes too slow we should
easily be able to switch to a file system approach.
Good luck,

The Wiki is your friend:
http://wiki.apache.org/struts/StrutsFileDownload
Specifically, you will be interested in the downloadapp.zip sample I
posted there... it has an example of serving a BLOB from a database. All
you need to do is have a mapping to this Action, and use it as the src
attribute of an img tag.
As another poster said though, there is definitely a fair amount of
overhead to doing this. That being said, I've done it to good effect on
at least two occassions. But, you do have to think about whether it is
appropriate... in my case, it was a client's logo in a frame that only
changed when the user changed clients, very infrequent. I can't imagine
I'd serve images from a database if it was going to be needed a lot... I'd
have to have an exceptionally good reason for doing it. Maybe you do :)
In any case, that sample app should show you how.
Note too that even if you aren't using a version of Struts with the
DownloadAction, what's there is still somewhat applicable, and there's
nothing to stop you from bringing DownloadAction over to your app anyway
AFAIK.
