RE: Need some Multibox help.
You most-definitely need to instantiate a bean named feature. The
reason it "Cannot find bean feature in any scope" is because there is no
bean named feature in any scope. In a real-world application, you would
probably do this in an action via getSession().setAttribute("feature",
new Feature(...)) or request.setAttribute(...).

RE: NullPointerException at ActionServlet.java:1003 using JRun4; work OK under Tomcat/JWSDP1.2
I have solved this myself. It appears that JRun4 considers
"tim.web.xml" as part of "web.xml", and so it tried to load a config
file that did not exist.
(Any Struts developers reading?? -- Would it be possible in a future
release of Struts to actually say "resource not found:
/WEB-INF/module/struts-config-module.xml" rather then
NullPointerException?)

NullPointerException at ActionServlet.java:1003 using JRun4; work OK under Tomcat/JWSDP1.2
All,
I have a struts application using modules which deploys fine under
JWSDP1.2/Tomcat (5, I think), but when I deploy it under (trial edition

Peeking at the source, it looks like it's trying to read a config file,
presumably for my module.
Anyone seen this before? How did you overcome this problem?
Thanks,
Tim

RE: Problem with action chaining
Ted, I'm not sure how scripting will help. The page designers (or customizers in some cases) will have to know some scripting language, and someone (probably me) will have to support some additional mechanisms for the scripts to do the DAO work (design, develop, test, ...) I dug out your book, and carefully read section 8.4 "Chaining Actions". It says basically what you've said in this thread (good thing, eh? ;-) ) and in general I agree. However, I still have a case where I think the chaining is valid, and that comes when using the validator, and the input parameter points to an Action. Suppose I have a list of objects in the view, and I click the edit button next to one of them. The resulting URI becomes something like /EditObject.do?ID=102. The mapping for /EditObject.do points to com.mycompany.actions.ObjectAction, parameter="load", and the forward goes to /ObjectEditor.do, which has validation=true, forwards to a tile, and has input="/ObjectEditor.do". This way, the initial load of the object to be edited comes from the DAO, and if validation fails, the validator points back to the editor page, leaving the "incorrect" input in the form to be corrected, rather then starting with the DAO value of the data (this way, the error messages make more sense.) I think my original posting may have been misleading to a degree. I was suggesting writing new (additional) ActionMappings to reuse existing Action classes to create new views.

RE: Problem with action chaining
Ted, Thanks for the reply. Putting methods in the base action(s) works (since the actions are related by what attributes they add to the request or session.) The down side is that the page designer who is ignorant of Java (or may not have access to the code) can't make changes this way. If I have an action to retrieve each business object and put it in the request (session) under a known key, then the page designer can chain these together to produce the objects necessary for the view. I hesitate to say that the actions are "doing actual work", other then the bare minimum - access the DAO to get a (list of) object(s) and place it (them) in a request (session) attribute. (Background note -- I have a requirement where there will be customizations done by field engineers at various customer sites. They need to know how to move tiles around (new layouts), and understand basic struts tag libraries, and HTML [which they already know]. By chaining actions, they can use the existing .class files without us shipping the java sources and having them modified in the field.)

RE: Problem with action chaining
So is it a bad design if you have Action1 -> add CollectionOfObject1 to request Action2 -> add Object2 request And then chain them together to produce two request attributes? I have some pages which display a list of Object1, and other pages which require the Collection to populate a select. So I define action path 1 to be action 1 and forward to the display for the Collection of Object1, and define action path 2 to be action 1 forward to action 2 forward to editor page which has a select of collection of object 1, while editing Object2.

RE: [OT] reload servlet without restarting the application
You can make a simple servlet that reads the properties file and sets the log level. Then simply reference your simple servlet (heck, make it an action if you want) via its URL and it will re-read and reset the logger. If you want to get fancy, you can event export all the properties you find and make a form out of them, so you can enable various loggers on the fly.

RE: [OT] Log4J and Pre-Processor
Would you rather have that 5ns, or the ace-in-the-hole where you can
debug your app in an installed production environment by turning on
(assuming you don't use the final static boolean method) the appropriate
logger? This has been extremely helpful in debugging. It also catches
lots of things you wouldn't ordinarily see, like when you add this to an
ActionListener more then once and you see your actionPerformed() get
called more then once. It's also useful for profiling.
The biggest savings with if (logger.isDebugEnabled()) { } comes when the
logger generates lots of StringBuffer objects, costing memory and
garbage collection, which will significantly impact performance more
then the if () to check whether to do it or not.

RE: Tiles setup question
What does /myapp.index map to? Typically, a global forward maps to
/someaction.do. The action does its controller thing and forwards to a
tile (or other) for the view (or next action).
The example lines (Your-*) below were snipped from my working struts
webapp, so I'm pretty certain they work.

RE: Tiles setup question
The global forwards work for struts taglib tags, generally as the value
of the name="" attribute. They do not export to the web server (servlet
mapping, *.jsp, etc.) level. Thus, to access the forward you defined:
You would say:
[Return to main menu]
However, the target of path cannot be a tile, it must be an action which
forwards to the tile. [Is this true? I have never seen a tile as a
global forward target]
Here is an example:
Your.jsp:
<%@ taglib uri="/tags/struts-html" prefix="html" %>
[return to main menu]
Your-struts-config.xml:

RE: how to submit form using
This works for me:
Done
Put whatever javascript you want in the onclick handler.

RE: How to detect that session has expired ?
You ought not to refer directly to any jsp pages anyway. Always refer to an action which forwards to your jsp. Then you can put your JSPs inside WEB-INF if you want (insures they can never be directly accessed) and you never have to add any tag(s) to check for valid user. As Ed points out, Inheritance is your friend. Get to know him, and his cousin, Poly. Poly Morphism.

RE: from Action to Facade: simple attributes or Business Objects
The philosphy is that the Actions ("controller") move bean properties
from form bean(s) into business beans, and pass the business bean into a
business object to perform an operation. I.e., the action should
contain all of (and only) the web-specific portion of the application.
I.e., the latter case in your example. Think about what happens if you
add a property? How many places do you need to change it? One less (at
least) in the patter case. You can (typically) use BeanUtils.populate()
do move all properties in one fell swoop.

Deploying a struts application (WAR) under ColdFusionMX
Hello all, I am looking to build an add-on web application to a legacy coldfusion application. I have got a prototype working under tomcat and now I want to "deploy" it to the cf server. It appears that I cannot simply load a war file, nor can I unpack it under cfusionmx\wwwroot. Both apps need to be in the same application server so I can share session data (for single sign-on, database resources, etc.) Has anyone done this? Are there any resources available? The MacroMedia web site suggests (which I also discovered on my own) that you include the struts action servlet definition in the cfusionmx\wwwroot\WEB-INF\web.xml file, but I am concerned about install/uninstall-ability of this web app (there will eventually be as many as 8 of them, and we want to add/remove/upgrade them at will). Eventually, the legacy app may move away from cf in which case we can easily use any app server that suits us. The choices I think I have so far are: 1. Do what a reasonable container would do and manually "merge" the add-on to the main (cf) application, adding the ActionServlet mapping to the cf web.xml. 2. Drop cf as the web application server and use tomcat, moving the cf servlet pieces into their own web.xml (putting the cf part in its own context/web app). This is effectively the reverse of #1. 3. Figure out a way to make cfusionmx accept the .war or some archive or hierarchy like tomcat would. 4. Figure out a way to make a .car (coldfusion archive) out of my .war I'm looking for help with option #3 (preferred) or #4.
