Dave, of course I know the URL is avaliable from HttpServletRequest. I

you didn't read my previous e-mails on the topic.
I couldn't find a way to get the remaining part of the URL after the
action's name. That is, to get /chapter1/1.html in
http://localhost:8080/action.do/chapter1/1.html
request.getPathInfo() always returns null.
I'm actually a little surprised your Action is firing at all if you're
doing *.do mapping and passing in something that doesn't end with *.do.
If you use /do/* mapping and pass in something that isn't "actively"
being mapped (i.e., mapping from "/do/chapter1/1.html" to an Action) I'm
not sure I'd expect Struts to handle this.
Now, if you do something like a wildcard mapping and define how you want
that to work (i.e., mapping from "/do/download/*/*" to an Action) you'll
probably get further--I'd look in to that.
For instance, I created a generic CRUD action class that mapped
"/do/admin/*/*" and "/do/admin/*/*/*" and stripped out chunks to get
table names, commands, and ids.
Also check out ActionMapping.getPath():
"Return context-relative path of the submitted request, starting with a
slash ("/") character, and omitting any filename extension if extension
mapping is being used."

Subject: Re: AW: [Solved]Cannot find ActionMappings or ActionFormBeans
Okay, thanks to everyone for all of their help. My problem was my
directory structure. I googled around to find some examples, and found
this page: http://www.jguru.com/faq/view.jsp?EID=531027
I had my JSP pages in the same directory as my struts-config.xml file.
So, I made a DatabaseRetrieval directory where I could put my JSP
pages, made a WEB-INF directory inside of the DatabaseRetrieval
directory, modified the web.xml to reflect that it was now
/WEB-INF/struts-config.xml and then tried recompiling. It worked!
Thanks again.

If you cannot explain where your struts-config.xml file is located,
then maybe you would prefer to search the net first. Look for
something like "(Java OR J2EE OR Struts) web application (directory OR
file) (packaging OR structure)".

Huh?
So, where is your struts file? Michael's saying that you probably
don't
have it in the right place, namely, under WEB-INF. The WEB-INF must

Subject: RE: Bean association with form
Hi Michael
Okay, I'm starting to understand the problem.... let's look back at the
JSP
<html:form action="SaveMappingElement">
Disclaimer: I know there are lots of variations in how you can use Struts,
so some of
what I'm saying is from my app that works and how the coding differs from
yours.
Yours may not be wrong, it maybe just different to mine, but how different
does it need
to be before it becomes wrong, I'm not sure about.
It could be that your form is not being identified as an action in your
struts-config.xml.
I'm guessing your action servlet setting is something like "*.do", in
which case your
action on the form needs to reflect "*.do". Try:
<html:form action="/SaveMappingElement.do">
Also, in your struts-config.xml you have lots of actions (which is
normal). You only
specify the name="{form-bean}" on the action that will receive one of
these forms. For
example,
<action path="/ShowTheAddPage" type="..." scope="request">
<forward.../>
</action>
<action path="/ProcessTheAddPage" type="..." name="MappingElement"
scope="request">
<forward.../>
</action>
Kind regards

So I am still at a loss as to why the bean was not getting associated
with
the html:form tag.
Adding the name attribute to the input tags works but WOULD be redundant
if
the html:form tag was working properly.

Subject: Re: Bean association with form
As long as you have your mappings setup correctly (and use the right
attribute name if you push the form bean into the request/session
yourself),
the <html:form> tag locates the appropriate form bean automatically and
the
name attribute is redundant.

Laurie is right, you need the extra action mapping in your config

I have also been adding the attribute name to the form elements as in:

Is this necessary? It works but I'm wondering if it is redundant?

When I run it the SaveMappingElement form is not populated but the
MappingElement bean is present and the bean:writes show the data that
is
populated.
Why doesn't the html:form tag pick up the MappingElement bean?

Subject: Populating a select box from a database
I want to populate a select element with items from a database. The items
can be retrieved by making calls to an API that retrieves data from the
database. These API methods may throw exceptions if the database is
inaccessible, or if the user is not logged in. The items only need to be
retrieved once per session, and should therefore be cached in the user's
session.
What is the best way to do this in Struts? Where should I make the calls
to
retrieve the list items? If I do this in the ActionForm, I am not sure
what
to do if an exception is thrown (for instance, if the user is not logged
in,
how to forward to the login page).
I've looked around for information about how to do this, but haven't found
much. Any help or pointers to resources would be greatly appreciated.
Thanks,
Rob

You want to do it in the Action instead of the ActionForm. You can
catch/handle any exceptions you want to and forward as appropriate, or
let the exception propogate and use declarative exception handling to
serve the appropriate page.

Subject: Re: Populating a select box from a database
Another suggestion is to use the DependencyFilter in Java Web Parts:
http://javawebparts.sourceforge.net/javadocs/javawebparts/filter/DependencyFilter.html
(I seem to be offering this suggestion a lot lately!)
With the DependencyFilter, you could define in an XML file what is
essentially a "managed" object to be created and stuffed into session.
You can do a bunch of different initializations with the object,
including calling methods on it or passing it off to another object to
initialize, either of which would probably fit your requirements well
because you can do whatever you need to at that point.
You *could* even create an ActionForm using this filter and populate it
accordingly. In fact, there is some details on doing that out on the
Wiki now:
http://wiki.apache.org/struts/PreInitializeActionForm
I don't know if doing the ActionForm is the best answer, but it should
work just the same.
I'm not sure how you could handle the error situations though... the
only suggestion that comes to mind is to have a check downstream from
this filter (either another filter or the first Action that executes as
part of your application), and if the object isn't in session and
initialized properly, then redirect to the logon page, or otherwise
appropriately handle it.

Subject: Tiles and tile definitions
I am having a problem with the tile definitions and the paths contain
therein.
My dev directory is setup:
web \
+ WEB-INF \
| \ tiles-def.xml
+ _common \
| + layouts \
| \ mainLayout.jsp
| + tiles \
| \ _header.jsp
| \ _footer.jsp
+ pages \
\ Test.jsp
I can create jsp pages which use tiles via the insert method. However
when I try to use a definition file things fall apart.
I have the tiles-def.xml in WEB-INF and in there is defined
<tiles-definitions>
<!-- main layout -->
<definition name="main.layout" path="../_common/layouts/mainLayout.jsp">
<put name="header" value="../_common/layouts/tiles/_header.jsp"/>
<put name="footer" value="../_common/layouts/tiles/_footer.jsp" />
</definition>
<!-- test page -->
<definition name="test.page" extends="main.layout">
</definition>
</tiles-definitions>
So essentially when test.page is created it will create a page with the
just header and footer. This is a test to get it working only - all the
other stuff (body, etc.) has been stripped out.
mainLayout.jsp consists of
<%@ taglib uri="/WEB-INF/struts-tiles.tld" prefix="tiles" %>
<tiles:insert attribute="header" />
<tiles:insert attribute="footer" />
and Test.jsp is only
<%@ taglib uri="/WEB-INF/struts-tiles.tld" prefix="tiles" %>
<tiles:insert definition="test.page" />
Now nothing appears when I try to open Test.jsp from a page that has
uses the <tiles:insert> method - the file is empty, no errors or
anything. I have the feeling it is something to do with paths but
removing ../ and various combinations doesn't seem to work.
