A form with valiable number of beans
I am trying to use Struts to create a page where I am editing an Entity (e.g. an order) and a variable number of sub-entities (e.g. order lines). I have corresponding beans in my session (an Order bean with a vector holding a number of OrderLine beans). I would like to have certain properties of all sub-entities open for editing and the page being recreated with all the values if it is submitted and the displayed again. How could I use the ActionForm and the tag-library to be able to use the automatic population of the properties of the form bean? I have tried to use the logic:iterate tag to build the list of order lines but stumbled on the naming of each text field. For example, the quantities field would have to be named "quantity1", quantity2", etc. If I use the form:text tag I can specify the bean and the property, but this gives me an identical name for all "quantity" fields. Even if I manage to uniquely name the fields, how can I create an ActionForm with corresponding properties to be set by the framework. Maybe I have to do this manually? Any suggestions how? If this has been discussed before, please point me to an approximate time frame. Regards, Lars Andersson
Struts+Weblogic+WARs
Hi! I'm using weblogic(sp6) with Struts and the WebAppStartup class, which was posted in the struts-user list. My problem is, that i want to use the weblogic property "weblogic.httpd.defaultWebApp", so my problems with the context path would vanish (and i would like to have this webApp in the root of the server). But unfortunately the WebAppStartup.class needs as a parameter the virtualName of the webApp, which does not exist... The source of WebAppStartup uses "ServletContextImpl servletcontextimpl = servletcontextmanager.getContext(s1);" to find the jsp pages which should be precompiled. Unfortunately the servletcontexmanager is not documented in the API-Doc, so i need some advise here Any hints? Sorry, if this is wrong mailing list, but i found the source of WebAppStartup here and it seems that there more weblogic users. Thanx Andre

Reuse is a tricky thing to acquire. You can't reuse too much neither too few. There are other risks with tags, while components, like component super overloading (too few tags that make too MANY things) or component superabundancy (too many of them doing ALMOST the same things). Or, as I commented, what if the tags just aren't adequate ? What I was trying to say there is that the argument must be based in all the shades of gray, and there's no such thing as "THE TRUE POWER" of Struts in rigid application models. As far as I'm concerned, I see the true power of Struts in its ability to accommodate all those situations and still providing a sound and elegant alternative for each case. It is that what seduced me into the project. Regarding the article, I see it providing some interesting ideas for a problem Struts has: excess of beans we have to code for LARGE applications. There's no technical argument to break the resistance against a BORING procedure (culture ALWAYS breaks technique - we must remember that). I provided once a tentative solution creating some tool (FBBuilder - form beans builder) to try to figure the beans out automatically. Didn't get much response (I can understand that). This is another approach, generalising the bean concept. We will have to figure out something about that problem, and this seems to be a good candidate.

EJB references
Hi Jim and Alex,
I think both of you understood me wrong. I am not planning to access EJBs
from JSP pages at all. I will have a lot of session EJBs to manipulate
Entity EJBs. But, the suggested approach accessing them from servlets was:
- Declare EJB references as private member variables
- in init() of servlet: initialize enterprise naming context, use that
context to call lookup to obtain reference, use reference to call portable
remote object's narrow method (see an example below)
BEGIN EXAMPLE
public class myservlet extends HttpServlet throws ... {
private CustomerHome m_home;
public void init() ... {
try {
Properties p = new Properties();
// ... specify some JNDI properties specific to the vendor
Context jndicontext = new javax.naming.InitialContext (p);
Object ref = jndicontext.lookup("CustomerHome");
m_home = (CustomerHome) PortableRemoteObject.narrow(ref,
CustomerHome.class);
} catch ... {
}
END EXAMPLE
Then you hold on to m_home reference and reuse it in each thread that
accesses your servlet. So, my question was, since I am going to have many
m_home(s) like this what should I do? If I put those in each action class
then every single time I am going to do above procedure (very resource
consuming). Or, should I create private member variables in action classes
and hold on to those home references? As Craig recommended, to create a
startup servlet and initialize those in there. But, how am I going to make
all of those availbe to action classes (If this is very simple, pardon my
knowledge. I am new to using EJBs)?
If you can give me some more ideas I really appreciated it.
Thanks,
Misak

Rewriting the URL in a form:form action
I've got a system with a large number of JSPs that I'm developing using Tomcat 3.2 and Struts 1.0 (12/4 nightly build). Because of the large number of files, I've started organizing the them in subdirectories. This has caused me to run into a problem, however. There doesn't appear to be any way to cause the URL in a form:form tag's "action" parameter to be rewritten using the webapp's context path. As a result, if I use an action="x", it directs the action to x in the current directory, which in my case isn't what I want. If I use an action="/x", it directs the action to the x in the web server's root directory - not the root of my webapp context, which is what I want. I tried embedding form:rewrite page="x" inside the action= of the form:form, but predictably that does not make jasper happy at all: "Attribute has no value" - note the empty attribute name in the message. Does anyone have ideas on how to make this fly, or do I simply have to go back to a flat directory structure? -- Erik

Because of the large number of files, I've started organizing the them in subdirectories. This has caused me to run into a problem, however. There doesn't appear to be any way to cause the URL in a form:form tag's "action" parameter to be rewritten using the webapp's context path. As a result, if I use an action="x", it directs the action to x in the current directory, which in my case isn't what I want. If I use an action="/x", it directs the action to the x in the web server's root directory - not the root of my webapp context, which is what I want. I tried embedding form:rewrite page="x" inside the action= of the form:form, but predictably that does not make jasper happy at all: "Attribute has no value" - note the empty attribute name in the message.

Re: EJB references
You probably need to create a helper class that does all this work, keeps the references as public variables and create it as a singleton in the init of the servlet, and store it as an application wide variable so you can access it easily and have references to all the session beans. I can't remember the deal though with synchronisation and EJBs, you had better check on that as there will be a high possibility of multiple threads (servlets) accessing it at the same time.

Mildly complex bean:message situation
Hi all.
I'm working on a moderately large webapp based on Struts 1.0 (nightly
build from 12/4), and I've run into a situation I can't figure out how
to handle cleanly using bean:message.
What I have is a sentance in which only some words are hyperlinked to
other pages within the app. The sentance has to be localizable, and
the hyperlink potentially needs to be rewritten to include the webapp
context path and session id.
The problem, of course, is that
bean:message key="foo" arg="uri"
won't work, because I can't use form:rewrite for the uri arg.
Any ideas?
Also, how do you experts handle the issue of localizable messages
involving a count, as in
There are {0} messages waiting.
If {0} is zero, I'd like it to read
There are 0 messages waiting.
If {0} is one, I'd like it to read
There is 1 message waiting.
If {0} is two or greater, I'd like it to read
There are n messages waiting.
Do I *have* to break down and use a scriplet just to pick the right
message from the bundle, one for n=1 and one for the other cases? Are
there going to be problems with that approach in other languages (I
would think so)? Should I be constructing this particular piece of text
in the preceding Action class, and passing it as a session or request
attribute?
What's your approach to this cases?

Message formatting goes through java.text.MessageFormat calls. You gain
access to all the formatting power of messages resources, like conditional
formats...
Instead of a cut and paste from the javadoc, have a look at
http://java.sun.com/j2se/1.3/docs/api/java/text/MessageFormat.html where
there's an example that you can apply to your problem. And perhaps you'll be
able to solve the first one, too.

I18n In Struts
Greetings, I am relatively new to this alias but not to the struts paradigm. I did much of the work on the Java Petstore Demo web tier where we in the past have used a very similar architecture. Prior to doing the Java Petstore I working in the Sun Global Products engineering group where I wrote internationalization tools. Regarding Internationalization. I believe much of this can be done through a templating mechanism. In Petstore we use a very similar templating mechanism to struts which allows us to define virtual screen names which are mapped to xml based screen definitions in separate files (one per language). In struts this would be mapping the forward page to a forward screen name (a screen is composed of all the elements (JSP pages and included text) which make up a single view that a user would see. The screen definitions are defined in xml and is encoded in Unicode which allows us to do much of the localization by either including a separate file or including the localized text directly. In this model we have one screen definitions for each language. To add another language the developer need only add another screen definition file along with the JSP pages that require full translation. Each language will also have its own template which is specified in the screen definitions file. This model also supports partial localization in that you can translate individual elements that make up a page. The user can change language on the fly using an action. We have a working localized version of this in the Java Petstore Demo 1.1.1 located at http://java.sun.com/j2ee/download.html. Though the demo is not pure struts (yet) I believe this same methodology may be beneficial in struts. I encourage feedback and comments on this method of internationalization/localization using templates. regards, greg
Re: Rewriting the URL in a form:form action
I had suggested: form:form action="%= request.getContextPath() %/x" as a possible solution to the form URI getting the context problem. But in another thread, Richards-san pointed out (asked?): And although we can so things within % % tags, it is not preferred? So, I guess that the politically correct way would be to extend the form tag to take an attribute like: form:form action="/x" usecontextpath="true" Wasn't something like this brought up with another tag ealier? -- Michael Westbay Work: Beacon-IT http://www.beacon-it.co.jp/ Home: http://www.seaple.icc.ne.jp/~westbay Commentary: http://www.japanesebaseball.com/
Re: design question
Jim Richards wrote:
As I understand it, is the basic design of struts generally to avoid
any direct java code in the .jsp files, and do everything through tags?
Tags and beans, yes.
And although we can so things within % % tags, it is not

That's the conventional wisdom; however, IMHO it's sometimes
permissible to use scriplets. Consider this JSP page:
%
java.util.Enumeration e = request.getParameterNames();
boolean hasParams = false;
while(e.hasMoreElements()) {
String name = (String)e.nextElement();
String[] values = request.getParameterValues(name);
hasParams = true;
for(int i=0; i values.length; ++i) {
String next = values[i];
if(i == 0) { %
b%= name %:/b %= next %
% }
else { %
, %= next %
% }
} %
% }
if(!hasParams) { %
iNo parameters with this request/i
% } %
The JSP page listed above prints request parameters, which is useful for
debugging. I refer to JSP pages that are mostly scriptlets with a small
amount of HTML sprinkled throughout as JSP components, for lack of a better
term. In such cases, I believe scriptlets are just fine.
Of course, the functionality in the JSP page listed above could be
implemented as a custom tag. Whether you implement JSP pages or custom tags
is largely a matter of taste. Custom tags are a little more difficult to
develop, but they are easier for page authors to use. JSP components are
easier to develop, but they are a little more difficult for page authors to
use because they must be included.
Just wondering before I embark on my project, if it's worth including the
design of any extra tags, or just doing the things I want in % % ...
The bottom line is twofold: reuse and division of labor. You can't reuse
scriptlets buried in a JSP page, but you can reuse custom tags or JSP
components. If you're on a large project with software developers and page
authors, ideally you'd like the page authors to use tags implemented by
developers. This helps maintain a division of labor where software developers
and page authors can work in parallel, with few dependencies.

Re: design question
One issue not really discussed is the performance aspect of using tags. Looking at the generated Java source from a JSP, a single tag can be expanded into 5 or more lines of Java code. For a simple tag like "ifNull", I would think using scriptlets with a if statement will lead to better performance (although I've NOT done any timing measurement). Just my two cents. --- David Geary [EMAIL PROTECTED] wrote: Of course, the functionality in the JSP page listed above could be implemented as a custom tag.

Subject:Strugs Orion JNDI
The following error that occurs in ActionServlet's
startup with the
newest
Struts nightly build and Orion:
register('-//Apache Software Foundation//DTD Struts Configuration
1.0//EN',
'jndi:/home/jblum/web/struts/WEB-INF/lib/struts.jar/org/apache/str
uts/resour
ces/struts-config_1_0.dtd'
resolveEntity('-//Apache Software Foundation//DTD Struts
Configuration
1.0//EN',
'http://jakarta.apache.org/struts/dtds/struts-config_1_0.dtd')
Resolving to alternate DTD
'jndi:/home/jblum/web/struts/WEB-INF/lib/struts.jar/org/apache/str
uts/resour
ces/struts-config_1_0.dtd'
seems be caused from the following line in
ActionServlet.java (about
line
881):
URL url =
this.getClass().getResource(registrations[i+1]);
when this is replaced with:
URL url =
getServletContext().getResource(registrations[i+1]);
the dtd is found and everything works.
However you have to rebuild struts.jar - but that is easy ant.
Hope this helps!

As this requires changing the source, I kindly request that the Struts
development team could fix this also.
This statement again depends on the container correctly implementing the
class
loader they are using for web applications.
My understanding is that Struts has been working fine with
previous versions
of
Orion. It sounds like they changed something in the latest
code. If so,
they
should change it back.
