JSTL Map Accessors
Hello, I have a problem that I can't seem to get around. I have a number of maps in my request, all keyed by same sequence of String keys that are contained within an ArrayList in that same request. My question is how do I get to the values in those maps? I've tried variations on: but that obviously looks for entries keyed to "masterKey" and not the value contained in the masterKey variable. How would I evaluate masterKey before firstMap[] is evaluated? Is that even possible? What are my alternatives?

html:submit button
Hello, >From what I understand, the value attribute on html:submit button is both the value of the label and the value submitted to the property attribute when the button is pressed. Is there a way to separate those two? I need 10 buttons, all the same label, but with different values submitted, depending on which button is pressed. I am not sure how to achieve that with html:submit. Should I just throw in a regular tag instead?

Re: can someone help me?
What is your action mapping for majprospect action?
Since your form is going to be submitted to majprospect.do (you need
to add .do in there) your action mapping should basically have a
name="prospectForm" in it.
Also, to make sure your form is being named correctly:
request.setAttribute("prospectForm", form);
(if you are setting the form in request, make sure that the action
mapping for majprospect also has scope="request" otherwise it will be
looking for the form in the wrong scope)
I assume that the form has values prepopulated already and that you
have checked that before you exit that action all the values that need
to be there are there.

Re: Input with name different than bean name property
There is a value attribute in the tag >From what I understand you have a form bean that has id and parentId as properties. You have a child object with an id property, and you have a parent object with an id property. So you could have and That is, you can do this if you use JSTL. You can do the same without -el tags and with code snippets but I just don't even want to think about those.

Servlet help for a Struts programmer
I have an strange request: While I am very familiar with Struts (I've worked almost exclusively in Struts for last 2 years, right after college), I have only basic knowledge of actual Servlet programming. Now I am faced with a task of updating and maintaining a pure Servlet application. Does anyone know of a resource (or resources) where I can compare servlet functionality to struts functionality. I know they are related, but (for example) I miss having a Struts config file, where I can glance at one file and see all my action mappings. Is there anyone there in a similar situation? How are you coping? Thanks, Denis - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Servlet help for a Struts programmer
I am sure that in a week or two that might be apparent to me. However right now I am exposed to everything that ActionServlet and MultipartRequestWrapper hid from view. Using Struts in my programming, the controller part of the MVC was hidden. For example, one of the first questions I had was: How in the world do I control where a successful action will forward to? Where do I set that? My questions are pretty much in that ballpark. :) On Tue, 10 Aug 2004 12:40:50 -0700, Michael McGrady <[EMAIL PROTECTED]> wrote: > At 12:29 PM 8/10/2004, you wrote: > >Nope.. you misunderstood his question.

Re: Servlet help for a Struts programmer
Wow. I unleashed a beast. Next time I'll ask the question way before I have to leave work. I have to thank you all for your input. The discussion on Servlets and Struts and how they relate (or don't) was in itself very helpful to understanding how the things work. I will take your advice and tutorials and start from web.xml. One of the things I love about my job is that I always learn something on every project, be it Struts, or a taglib or (in this case a "missed step") Servlet. Thank you!

Re: Losing request attributes
In order to keep the actual entries that the user typed in (so they
don't have to retype everything if they changed a bunch of things) I
usually put the entire form and errors into request if there are
errors.
Then you need to make sure that your populate action checks for
presence of the form in request and overrides the DB entries with the
ones in the form.

[OT] Setting up a struts project in IDEA
Hello, I switched to IntelliJ IDEA 4.5 recently and I finally got an opportunity to set up a pure struts project for a demo. I unpacked struts-blank, and guessed at various settings IDEA asked me when I tried to set up a project. Now I can't get the IDE to recognize the tld's anywhere, I am not sure what path root it is using or how to set it. I've tried searching online for a tutorial on how to set up a struts project for development in IDEA, but I didn't have any luck. Is there anyone out there using IDEA 4.5 that has a list of settings, paths and other things that need to be set in order for all the bells and whistles to work?

Load-on-startup init servlet
I am trying to set up a start up sequence for my app but I have never set up something like that. Basically I want to initialize some classes with attributes found in my resources file. How would I go about doing this? I set up my web.xml file to load a servlet on startup, but I am not sure how I am supposed to get to the message resources that are loaded in the ActionServlet. I know I saw this done before but I can't remember how it was set up. Thanks. Denis - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Load-on-startup init servlet
So I can call MessageResources.getMessageResources("blah") in the init() method?
Is there an order I have to load the servlets in web.xml in order for
that to work? (if I remember correctly, ActionServlet actually loads
those resources, right?)

Filters
Hello all, Although I've been using Struts for small projects for a while now, I haven't really used filters. Now I am incorporating some functionality from another project into mine, and the other project used plain old servlets and filters. My question is this: In filter's doFilter method, is there a way to forward to a Struts action somehow? I need to populate the session and I have all this stuff already written, I just need to do a forward to the action somehow. How could I do this without request.getRequestDispatcher() calls? Or can I do it at all? I haven't wrote pure servlet in a long long while and I forgot a lot of things so please excuse me if my question is dumb.

Hello all, Sorry for the off topic post. I need to get some data exported into Indesign format, and I am not sure how to do that. Is there anyone out there doing this already?

Ancient (1.1) Struts Help - Map Backed Forms
Hello list,
I've recently moved jobs and landed in a position where I have to
develop with Struts 1.1 (don't ask me why they don't want to upgrade).
In any case, I need to use map-backed ActionForm, first time we're
doing this in the company looks like.
I am running into problems that I've previously solved by using JSTL.
However that is another no-no.
Basically the problem is this. When trying to access the page I get
this error:
javax.servlet.jsp.JspException: No getter method for property
value(officeCell_2001) of bean org.apache.struts.taglib.html.BEAN
at org.apache.struts.util.RequestUtils.lookup(RequestUtils.java:517)
JSP snip:
<% String curPos =
Integer.toString(position.getEmployeeId());
prop = "value(officePhone_"+curPos+")"; %>
Form:
public class MFEditForm extends ActionForm {
public MFEditForm() {
}
private String officeId;
private Map values = new HashMap();
public String getOfficeId() { return officeId; }
public String getValue(String key) {return (String) values.get(key); }
public void setOfficeId(String oid) {officeId = oid; }
public void setValue(String key, Object value) {values.put(key, value); }
}
from struts-config.xml
I prepopulate the formBean and set it in request. The formBean is
getting associated correctly with the form on JSP (I checked by
outputing the officeId without touching the map). Interesting thing
is that if I don't use getter methods (IE, if I use )
there is no error. It seems to me that the getter method is somehow
wrong, but I can't see it.
I tried these getValue signature variations:
public String getValue(String key)
public Object getValue(Object key)
public String getValue(Object key)
public Object getValue(String key)
It seems to me that this plain vanilla map backed ActionForm should
work without a hitch. Am I missing something really obvious? I
really can't use JSTL or EL tags so if there is a solution not
involving those, please let me know.
Thanks,
Denis

Forget that.
They're actually running 1.0.2. No map backed forms for me.

Redirect after a file download
Hello, I have an application that enables a user to download a file and keeps stats on total downloads as well as last time anyone downloaded a file. My problem is that the client wants the download page refreshed after a file has been sent. Right now I have a forward that points back to the download page (which would reload the stats from the DB reflecting the new download), but since I have something in the response in the download action it doesn't seem to follow the forward after sending the file. I am not quite sure how I should handle this. Does anyone have an idea? Thanks, Denis - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Redirect after a file download
I was unclear I guess. No, the refresh happens after the action
STARTS sending the file, at the beginning of the download.
This solution works with a timeout on the second window.location.
I was hoping I could do something else, perhaps forking control or
something after the response has is sent, but I didn't think it
possible.
The file is constructed in the action so it's not really a direct path
to the file, thus the need for the timeout (so the action has some
time to construct the file and write to DB).
Thank you for your response,
Denis
