struts-config.xml question
When defining an action element in the struts-config.xml file, we always utilize the path attribute. For example, I have two actions defined in my struts-config.xml *snippet* actionpath=/home type=foo.strutsApp.ContentAction name=contentForm forward name=fail path=/Login.jsp / /action actionpath=/login type=ginsu.strutsApp.LoginAction name=loginForm forward name=fail path=/Login.jsp / /action */snippet* Say I want to make the first action element be invoked by any path that starts with /home (like /homeshop or /homes). Basically, can I define a wildcard in the path attribute? I would like to have the ability to have a few different URLs mapped to the same action WITHOUT having to define all of those relative URLs in more action elements. In essence I would like to have something along the lines of: actionpath=/home* type=foo.strutsApp.ContentAction name=contentForm forward name=fail path=/Login.jsp / /action So that the path attribute is mapping potentially any number of relative URLs that begin with /home to this action. This would allow me some great flexibility for real time content updating. Is this possible? TIA. - Do you Yahoo!? The New Yahoo! Search - Faster. Easier. Bingo.
RE: struts-config.xml question
Hey, talk about exactly what I was looking for. Thanks, Jerry. I'm perusing the download right now. Anyone in this community using the Wildcard-Matched Actions project? Wildcard-Matched Actions Project: http://www.twdata.org/struts-wildcard/ It seems to be just 2 new classes with code pulled from the Cocoon project, and is dependent upon using Struts 1.1. I think upgrading to Struts 1.1 shouldn't be too hard. I've read some about this in the Struts in Action book -- great resource by the way. It would be somewhat comforting to hear from people who are utilizing this.

Can we 'hot swap' the struts-config.xml?
Is it possible, with an instance of a struts 1.0 webapp running in tomcat, to re-initialize the struts-config.xml while the application is still up? I say this because it would be great if I could edit the struts-config.xml as an admin of my site without disrupting the webapp and any potential end users of the webapp. I worry about synchronization issues.

No action instance for path your path name could be created
Hello all. I apologize for the size of this message,
but I thought it necessary to include some of my
source.
I am trying to do a very basic thing here. I trying
to pass form data to an Action object. However i am
getting the following tomcat error, when I submit from
http://localhost:8080/ginsu/test/addFile.jsp :
*** Begin My Error ***
HTTP Status 500 - No action instance for path /addFile
could be created
type Status report
message No action instance for path /addFile could be
created
description The server encountered an internal error
(No action instance for path /addFile could be
created) that prevented it from fulfilling this
request.
*** End My error **
I have consulted both the Struts in Action book as
well as the struts-example web app. I just don't see
where my problem resides. So I thought it best to
consult you more experienced struts users. My first
guess is that I have configured struts-config.xml
incorrectly.
I will first list my struts-config.xml file (which is
where I _think_ my error may be), my addFile.jsp (a
simple form), my AddFileForm (struts FormBean), and my
AddFileAction class (Struts Action).
I hope you guys can see something obvious. Here's
hoping.

RE: No action instance for path your path name could be created
Yes I am sure everything is compiling. I use ant to take care of my build and creation of my ginsu.war (ginsu = my web app name). In my build process, after a compile, I basically jar all of my class files into ginsu.jar, and this jar file winds up in my WEB-INF/lib directory. I basically deploy my application by dropping the ginsu.war into %CATALINA_HOME%/webapps, and restart my server. So I am sure the class is being created. --- Vivian, Nigel (N.)

how to invoke the action servlet?
I have been referencing the book Struts in Action by Ted Husted as well as the struts site. I cannot figure out what to point my browser to in order to invoke struts. I have zero JSPs in my struts application -- I have no need for them because I am utilizing Model X where I have one XSLT servlet that represents my entire view layer. I thought I could just point my browser to http://localhost:8080/ginsu (ginsu being the name of my web app). I realize I have no index.html or index.jsp, but I'm just trying to go directly to the action servlet from the browser. Is this not possible in struts?

Re: how to invoke the action servlet?
Ah, I am sorry. I forgot to mention that I had tried
different combinations of URLs. I did try
http://localhost:8080/ginsu/ginsu.do and I get the
same tomcat error as when I enter
http://localhost:8080/ginsu .
I also realize how vague I was. I'll try to be more
specific: I am using Tomcat 4.1.18, and I get a 404
with a description of The requested resource is not
available when I try these different URLs.
I went back to my %CATALINA_HOME%/webapp/ginsu
directory and discovered that my struts-config.xml
file was there. I think this is incorrect.
The web.xml file and the struts-config.xml file both
need to reside in my
%CATALINA_HOME%/webapps/ginsu/WEB-INF directory,
correct?
So I moved the slide-config.xml to the web-inf
directory and restarted tomcat and received the same
results.
Any further thought?
Thanks again, and I appreciate the fast responses.

The URL of an action is composed like this:
http://${hostname}:${portnumber}${contextpath}${actionpath}
So, if you install your webapp at context path
/ginsu, and you want to
invoke the action with a path of /ginsu (which
appears to be the only
one you've defined), the URL would be:
http://localhost:8080/ginsu/ginsu.do
since you are using extension mapping. The first
part (/ginsu) selects
which web application, while the rest (/ginsu.do)
selects the action.

RE: how to invoke the action servlet?
Heh, I must be getting tired. I did mean
struts-config.xml. The slide thing was a slip (I'm
also using jakarta slide as a content management
system).
The struts-example.war file works fine when placed
into tomcat. So tomcat and a well configured struts
instance seems to work on my machine...which means
something is wrong with my implementation. I will
take a look at the source for this example. I
appreciate your help and advice.
You'll hear back from me soon enough ;)

My suggestion to you would be to try and get the
struts-example.war running ...
Just put the war file in your webapps directory (or
unjar it there), then try to run the example. If
that works, you can slowly integrate your code into
that webapp. Surely you will find the point at
which it starts failing.
Good luck!
