check out struts-wildcard project!
Hello all. I've created a few struts applications with struts1.0 and struts 1.1rc. I've often found a need to update content on my applications. As in updating or adding new URLs. However, I could not execute live updates -- meaning I had to bring my application down, edit the struts-config.xml file, and restart. For most people, this might be fine. For me it was not. I would like to encourage people to take a look at http://www.twdata.org/struts-wildcard/ . It basically allows you to enable regular expressions in your action mappings. Plus, this is _really_ easy to use. I have a few actions defined in my struts application, but one really stands out: Any content request goes through this action mapping. So basically any relative URL within my context, "mycontext" that begins with "/view" will go to my ContentAction. So h**p://mydomian/mycontext/view/whatever.do will be sent to this action. Note, that I store my URLs and associated data in my own tailor made XML configuration file. This allows me to update and add new URLs without bringing my server down. I don't even have to edit my struts-config.xml. This project provided very key functionality to my application. I encourage you all to take a look at this project. - Do you Yahoo!? The New Yahoo!

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. Thoughts? - Do you Yahoo!? The New Yahoo! Search - Faster. Easier. Bingo.

RE: No action instance for path 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.)" <[EMAIL PROTECTED]> wrote: > Are you sure that you have a compilied Action class > where the webserver can > find it e.g > ...webapp/web-inf/classes/.../AddFileAction.class it > could be > that your Action class is not compiling > > Nigel Vivian > __ Do you Yahoo!?

No action instance for path 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.
* struts-config.xml ***
http://jakarta.apache.org/struts/dtds/struts-config_1_0.dtd";>
*** end struts-config.xml ***
And now my jsp form:
*** Begin addFile.jsp ***
Add an XML File to Slide
Filename:
** End addFile.jsp
My FormBean:
** Begin AddFileForm.java *
package src.ginsu.strutsApp;
import org.apache.struts.action.*;
public class AddFileForm extends ActionForm {
protected String filename = null;
public String getFilename() {
return this.filename;
}
public void setFilename(String filename) {
this.filename = filename;
}
}
** End AddFileForm.java
And finally, My AddFileAction class:
** Begin AddFileAction.java
package src.ginsu.strutsApp;
import ginsu.content.adapter.*;
import org.apache.struts.action.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.StringTokenizer;
import java.util.Vector;
import javax.xml.transform.dom.DOMSource;
/**
*
* @author tarkentond
*/
public class AddFileAction extends Action {
public ActionForward perform (ActionMapping
mapping,
ActionForm form,
HttpServletRequest
request,
HttpServletResponse response) {
AddFileForm addForm = (AddFileForm)form;
String fullPath = addForm.getFilename();
StringTokenizer tokenizer = new
StringTokenizer(fullPath, "/");
Vector temp = new Vector();
while (tokenizer.hasMoreTokens()) {
temp.addElement(tokenizer.nextToken());
}
String slideFileName =
(String)temp.lastElement();
String slideUri = "/files/" + slideFileName;
try {
ContentAdapterImpl adapter = new
ContentAdapterImpl();
adapter.initDomain("ginsunamespace", "root");
adapter.createFile(new
FileInputStream(fullPath), slideUri);
DOMSource dom =
adapter.retrieveXml(slideUri);
request.setAttribute("dom", dom);
} catch (Exception e) {
request.setAttribute("exception",
e.toString());
}
return mapping.findForward("xslServlet");
}
}
*** End AddFileAction.java
Thanks in advance for your time and effort looking
over this long email.

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 ;)

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.

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? Here is my struts-config file: http://jakarta.apache.org/struts/dtds/struts-config_1_0.dtd";> And here is my web.xml file: http://java.sun.com/j2ee/dtds/web-app_2_2.dtd";> action org.apache.struts.action.ActionServlet config /WEB-INF/struts-config.xml debug 2 detail 2 2 XSLServlet ginsu.XSLServlet XSLServlet /XSLServlet action *.do index.jsp /tags/struts-bean /WEB-INF/struts-bean.tld /tags/struts-html /WEB-INF/struts-html.tld /tags/struts-logic /WEB-INF/struts-logic.tld /tags/struts-nested /WEB-INF/struts-nested.tld /tags/struts-tiles /WEB-INF/struts-logic.tld I noticed that there is an element: index.jsp Is this an absolutely necessary element in the web.xml file? I figure the index.jsp would just contain a redirect to the action servlet. Any help is appreciated. Thanks! - Do you Yahoo!? Yahoo! Platinum - Watch CBS' NCAA March Madness, live on your desktop!
