Re: [Mav-user] Can't get dispatcher to work
Well this is indeed a blast from the past! You seem to be missing jdom.jar from your classpath as well. There will be a version in your maverick distribution, or you can find the latest version here: http://www.jdom.org/ Also, sometimes you can have class path issues if you have duplicate jars with different versions in your class path, so I'd check for that as well. Finally, Tomcat can be funky when it comes to where you put these jars, so you may have to play around with putting it (only) in WEB-INF/lib or one of the Tomcat shared directories. Are you actually contemplating Maverick or just doing research? Maverick is pretty dated, especially in an ajax-driven world. Post-Maverick I ended up developing http://tagonist.tigris.org/, which does most of what I needed from Maverick but in 500 lines of code... and now I use http://code.google.com/p/htmleasy/ + Cambridge for basic html rendering, although that tends to be fairly simple given that most data is rendered by javascript/ajax. And my 2c on that is that for years I've used Wicket (and in fact are one of the core contributors) but nowadays stay clear of Java web frameworks altogether. I tend to use just plain HTTP services using Jersey/ JAXRS and JavaScript directly (e.g. using jQuery, though I might throw in a framework like Angular). The only thing left then is something to dispatch requests and handle security. I use Wicket for that, just because I know it well, though you could just use a servlet filter for it or a light framework like HTMLEasy, which seems like an excellent choice.

Re: [Mav-user] Maverick activity and support
It's hardly active, but the source code is stable and quite accessible, and there are still a few people monitoring this list. Maverick is a nice pick if you like it's composition pattern (using transforms, which is kind of the inverse of, say, Struts' tiles), and I think the code is well organized and easy to follow and extend. Also consider looking at Stripes and Click if you want to go the web MVC route. Personally, I think that if you're considering developing your web interface in JS, you might be better off just developing your backend as services, maybe using something like Apache CXF or Restlet for instance. Unless your site is very complicated and you want to use a web MVC framework to structure the flow through your site.

Re: [Mav-user] Need recommendation as to what controller to use..
Yiannis, You can use FormBeanCtrlBase for thread safe controllers. It won't solve your problem though, as an instance of this will be created with every request (instead of the session you seem to be looking for). Why not just use an object to hold your questionaire data and keep it in the session? You can use the HttpSession just like you would with Servlets. Btw, though there will be bugsupport for an unlimited time on Baritus, it is not actively being developed as I am working on a new project (which is currently in alpha, but will reach beta in a couple of weeks from now). Session handling etc. is much easier with this project, and it is fully component based. It might take some time to get used to if you are used to web-MVC frameworks (Maverick/ Baritus, Struts, etc.), but if you're not used to the page oriented approach, you'd probably find this project much easier to work with.

Haha, really... what's so wrong about starting another technology? I
actually think it is one of the strongest points of the Java communtiy that
there are so many. Gives people choice (after all, why should Maverick have
been started when there was Struts), and the competition makes open source

I do use Velocity, and am happy with it in the contexts in which I
use it.
However, it didn't seem to quite fit here. I wanted the source pages
to be plain old HTML, to the greatest extent possible. So consider
something like a role-sensitive navigation bar. rather than
#if ($user.inRole('admin'))
a href=''AdminFunctions/a
#end
#if ($user.inRole('manager'))
a href=''ManagerFunction/a
#end
...
I wanted
a href='' ctl:if='${user.inRole(admin)}'Admin Functions/a
...
Also, I wanted to be able to leverage XML tools (XSLT) in interesting
ways. If the control elements are expressed in XML, then I could
(for example) pass a template containing a looping construct through
an appropriate stylesheet (I'm referring here to an offline process)
and get a reasonable looking mockup.
Another thing: I figured I'd be using XSLT at runtime. Both JSP and
vanilla Velocity are what you might call text oriented. Meaning
that the results of a template evaluation or JSP page evaluation
would have to be reparsed as XML on every request. I wanted to avoid
that overhead.
Certainly I could have used Velocity. I'm not terribly proud of
having increased the number of Java web technologies, and I always
figured I could resist the urge when it came upon me. But it turned
out I was wrong.

Subject: [Mav-user] a new view
I recently had reason to develop a new view type for Maverick, and
wonder if there might be any interest in it. If so, perhaps I can
contribute it back to the project.
The problem: I needed a very simple X?HTML template system. It had to
be something that, however, complicated under the hood, could be used
by junior developers and design people. I also wanted the source
pages to be valid XML, so that I could use the various XML tools to
edit/process/test the pages.
I wanted to avoid JSP's scriptlet syntax. JSTL might work, but I
wanted the source pages to be valid XML, so I wanted to avoid stuff
like
a href=c:out value='...'/ ... /a
Basically, I wanted XML source files, with the ability to dynamically
evaluate expressions and a some minimal amount of flow control.
Looping, for sure. Conditionals, probably. Something to match the
minimalist spirit of Maverick itself.
Something that might look like this (with some of the namespace stuff
cleared away):
html
body
h2Welcome ${user.fullName}/h2
Your order contains the following items:
table
ctl:for-each items='${order.items}' name='item'
trtd${item.productId}/tdtd${item.description}/td/tr
/ctl:for-each
/table
the current time is ${util.dateTime}
/body
/html
looks a bit like JSTL, but is required to be valid XML, unlike
JSP+JSTL. I used OGNL for the expression language.
The processing model goes like this: the page description (e.g. the
above sample) is loaded once at app startup and parsed as a stream of
SAX events. The events are recorded, and we do a certain amount of
pre-processing, e.g. joining and compiling text nodes. Then, at
request time we replay the event stream using a request specific
evaluation context that contains things like the current request,
the authenticated user, and some utilities. Maverick makes this
pretty simple, because we can grab the next transform step in the
view handler, and send the replayed SAX events on down the line.
This means that any XSTL we might want to perform can be specified in
Maverick's config, and will be handled completely by Maverick.
Another nice thing about this is that unlike using JSP+XSLT, where
the output of the JSP has to be re-parsed on every request, in my
system the source is parsed exactly once.
The strange thing about all this is that I wasn't able to find
anything that quite suited my purpose. So I guess that's one purpose
of this message: to see what I may have missed in the sea of Java
webapp frameworks.
The other purpose is to see if there's any interest in this. If not,
then I must have missed something, because I've been quite pleased
with the results. If so, then I can see about getting it cleaned up
and put out somewhere for the Maverick community to have a look at.

RE: [Mav-user] webwork, maverick and 24x7
Most servlet containers support hot-deployments. You should check out the usergroups/ documentation of the servlet containers you are considering for these features. My experience with various servlet containers (like Resin, Jetty, Tomcat, Websphere) is that it works allright if you play by the rules (like that all objects you put in the session are serializable). A pitfall is that some of these containers have (or at least used to have) memory leaks when utilizing the hot deployment features, resulting in performance loss or even VM crashes. And if you are considering building in hot deploy like features yourself, you can also start by looking at how the servlet containers try to accommodate it.

RE: [Mav-user] Controller chaining code
Hi, I did not actually follow the discussion back then, but I can tell you that we (me and collegues) use controller chaining very often. It works at least from Maverick 2.2.0 on. Besides the default support that Maverick has for it, I even took controller chaining a step further in the extension project Baritus (http://baritus.sourceforge.net), where you can do stuff like reusing a form in the chain and control whether population is done further down the chain and so forth. It's all Java though; I have no idea how this would work in Maverick.NET. And your question... I don't know where to find the source files, but you can do chaining just like this: command name=cmd1 controller class=MyCtrl2 / view path=myview.vm / /command command name=cmd2 controller class=MyCtrl2 / view path=cmd1.m / !-- this chains cmd2 to cmd1 (or should you say reverse) -- /command Eelco Hillenius -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Cort Schaefer Sent: zaterdag 10 juli 2004 1:31 To: [EMAIL PROTECTED] Subject: [Mav-user] Controller chaining code This post has a patch and talks about some additional source files - does anybody know where I can find them? http://sourceforge.net/mailarchive/message.php?msg_id=3805139 Cort --- This SF.Net email sponsored by Black Hat Briefings Training.

[Mav-user] New release(s) of Maverick (+opt)
Hi everyone. I just released new versions of Maverick and the opt packages. The changelog from 2.2.0: Version 2.2.2[6/27/2004] - Use Commons Logging instead of Log4J. - Log the stacktrace when reloadConfig() throws a Configuration exception on initialization. - A custom controller factory can now be provided. See the manual for an example. - Version 2.2.1[virtual] - Added support for URLs (http:, https:, file:, ftp:, jar:) as paths in XSL transforms. Also added support for monitoring 'file:' URLs and re-caching them upon change. - Redirects now properly encode session ids in the URL (if necessary). The only changes in the opt packages are the use of commons logging instead of log4j. Opt-fop - that I use for several projects myself - also has a fix for IE/ Acrobat 6 related (potential) troubles. I updated the docs with a short desc of the custom controller factory and an example of how it can be used, and I also added a short description of Baritus. Hope everyone has fun with it, and does not have too much trouble with switching to commons logging (probably not judging from the list traffic).

Re: [Mav-user] I want to switch to Maverick....
1. It sounds to me that you do not need a lot of different commands, but possibly a lot of different views... If you need to do some Java action on a specific request, you can do that with a controller. You will (probably) at least end up with the number commands that you need to have controller classes. On the other hand, if most of your processing actually takes place in the XSL processing, and most of the time your controller does little more than just getting the XML from your XML repository, you could just define one command for that, and e.g. use a request parameter to figurure out which view (and thus which XSL transform) to use. 2. If the above works for you, your configuration file is probably not that big. Note that you can define your views globally (with all the transforms etc.) and reference them in the command definitions. If it still is too big, see if pre-prosessing the config file with XSLT works for you. See configuration option 'configTransform'.

After a some time I ended up with Maverick.java We are running a live website using Cocoon2/eXist xmldb/xslt/jBoss and if possible move slowly towards Maverick, implementing the Maverick servlet alongside the cocoon servlet. I have read the manual looked at the examples downloaded the source and is very impressed of the simplicity of this implementation. 1. we have a ton of xml docs located in the eXist db. They are all transformed using xslt and serialized as html. I can do all this using xslt in Mav. without any problem but how do I serve all these html pages just using one command (is this right). 1a. can i use wildcard/regex in the command name=product_* ? 3. what html form template/validation system is the defacto standard with Mav. 4. does it require 2 Mav. servlets to serve /product/xx.html and /distros/xx.html. 5. can is split the maverick.xml file into more files so it would be easier to manage.

Re: [Mav-user] Eclipse plugin
I developped a first scratch that is like an XML editor - of which there are several useful plugins available, and probably will be part of the Eclipse distro sometime (http://www.eclipse.org/proposals/eclipse-webtools/index.html). However, it is a little bit smarter about views e.g. and potential functionality would be direct navigation to a defined controller class (you F3 in Java source files). But... too many other projects, too much hours of paid work to do, too many hobbies and festival season is here. I have stopped developping it and will not pick it up again either, as I think the rate of time I have to invest in it and it's general usefullness is not favorable enough. Now about the pluggable controller factory. Actually that has been the only functionality in Maverick I found lacking myself.

Re: [Mav-user] Site permissions and release plan
Actually it is not. You can still use Log4J as you did, but there's one more lib living in you app space now - if it wasn't allready there because a lot of project have a dependency on it. I really like Log4J and never used other logging systems when I did not have to. I do understand users who do not want to have the dependency on it when they do not use it.

It would be great if one of the project admins of Maverick could include a link to Baritus on the Maverick site. For the people who use Maven: the project is Mavenized, but as Maverick is not at the default Maven repo site (www.ibiblio.org/maven), you could include the repo http://test.topicus.nl/maven in your maven build.properties for the time being.

Subject: [Mav-user] Maverick webapp not visible anymore?
Hi,
This is probably a nwebie question that can be listed under really
stupid mistakes but here goes:
Last week I made a new webapp using Maverick and although the Database
Application it was connecting to had some problems (which are completely
besides Maverick so
these should not matter for this question) the commands I defined for
testing Maverick did work fine.
This morning I tried to start up Maverick to continue working but for
the life I could not get the webapp working! All examples etc. worked
fine, so Tomcat should be running fine, I did not get any weird messages
when starting up etc.
All I could get was:
type Status report
message /mticketing/welcome.m
description The requested resource (/mticketing/welcome.m) is not
available.
Even requesting a test html file did not work.
I tried to stop tomcat, clear the cache, reboot my machine, etc. but no
changes in behaviour.
Does anybody have a clue what I can do next to at least get the first
screen (which is nothing more than an HTML file) visible? I am getting
slightly mad here...
Thanks in advance,
Michiel

RE: [Mav-user] new user
Thanks for thanking ;)
I was wondering if anyone took a closer look at the example, and if
anyone has any comments.
I kind of forgot to explain my goals behind the framework. I do not like
the available validation frameworks because in those frameworks you have
to put type information etc. in a configuration file. Moreover, to keep
the error reporting working, you should use 'flat' forms with string
fields. Now, what I achieved in this framework is that:
1) You have standard typechecking and error reporting build in. If you
need an integer field, just declare it as an integer property in your
form. If user input is not valid for an integer, an error is recorded,
the original input value is saved as an override (in order to show the
user the value he or she submitted).
2) The ability to use 'deeper' forms (hmm, my English is lousy at
times... Sorry). E.g., you can have a form like this:
public class EditCDForm extends AbstractForm
{
private Long someId;
private CD cd = new CD();
// create empty instance to be able to populate it from the
request
...
And HTML fields like this:
input type=text name=cd.title
So, no need to construct the object anymore, as you allready have it in
your form. You could do:
Long newId = (Long)session.save(form.getCD()); // make persistent with
Hibernate
Besides, this gives you better structuring options, especially where you
reuse forms for different purposes.
3) Multi-line handling. In my form I could have:
private Double[] trackLength;
And in my html form I could have:
input name=trackLength size=10 !-- field one --
input name=trackLength size=10 !-- field two --
input name=trackLength size=10 !-- field three --
That should result in having my form populated with an array of three
doubles for field trackLength. If you look at the complete example, you
can see that the error reporting knows about these fields as well; if
you give invallid input for field two, there will be a saved error and a
saved override value for that field. It's a pitty that multilines only
work for flatt fields, but that's HTML...
As a final note, I do not:
1) Worry about javascript validation (which seems to be the key focus of
Jakarta Commons Validator). When I write webapps, I try to avoid
javascript as much as I can. Imho, you need to focus on the server side
validation anyway, and if you really need to write some javascript, you
better just write it and keep it visible (I *hate* all the JSP tags that
generate fancy stuff for you... makes it much harder to debug)
2) Take extra model information (like maximum field sizes etc) into
account. It's pretty easy to do by overriding
protected boolean validateForm(ControllerContext ctx, AbstractForm
formBean)
from AbstractCtrl. And if you want to do this automatically, I think you
want to do this at a central place (like a custom hibernate mapping
file).

Eelco

Fantastic! Thanks for the example!
I agree with Jeff that Maverich doesn't need documentation because it's
simple. It#8217;s 80/20 rule? 80% of the time you don't need
documentation for Maverick at all :~), but those 20% of rare cases will
make you read source. Just my $0.02.
Struts' online documentation is more targeted at novice inexperienced
developers, whereas Maverick is for those who tried everything else and
got
disappointed. This is one of the reasons Struts got so much attention
(7 books published!) despite the unnecessary complexity and all really
hard time it gives to its adopters.
So Maverick remains a hidden gem in ocean of J2EE application
frameworks.

Re: [Mav-user] Sitemesh or view transforms?
For what it's worth, here are my thoughts... I never gave Sitemesh a serious try, though maybe I should as it seems to be very popular lately. I must say that I think it does not give me much confidence looking at the release notes and looking at the pace that is worked on the project (which does not seem to be very fast for a project with quite a few outstanding bug reports). But... I could be wrong and maybe it is great to use. Now, about your top and side bars. Personally I would not have a problem to do some proper logic coding in the view (and maybe use some logic centric components to keep the view clean) AS LONG as you do not have to handle flow stuff in the top and side bars. The kind of processing that goes on in your top and side bars are - even if the processing is complex - probably allways the same.

Re: [Mav-user] Reload command in web.xml
I have to object to that (and I am not one of the maintainers). I think the documentation is good, taking the scope of the project and the provided examples in account. Moreover, I think it is one of the better written OSS Java projects around where it comes to clearity of design and code. In other words: you should not have any trouble understanding what's going on under the hood looking at the sources.

A couple of weekends ago I put together the first few chapters, and now having a weeks worth of Maverick under my belt, I'm definately going to include a segment on it. I'm wondering if anyone feels up to spending a bit of time acting as a reviewer for the book as a whole and particularly the Maverick section when I get to it. I haven't written that bit yet. :-0 When I get to that, I'll probably be asking a million dumb questions wringing every last bit of information and usage and example ideas out of the people in this group... My hope is the section of maverick will become the 'cookbook' for maverick **as long as the illustrious leaders are fine with this**... I know this should probably be done via serverside or someone, but the 'soon to be' maverick section really needs to be reviewed by people who use it. Whaddaya say Jeff? If anyone is interested, just drop me an e-line. I written about 93 pages so far, but it's only been a weekends work and has a few bugs in it, and I only get every second weekend or so to work on it (in between cooking and cleaning :-), so it'll be a while before it's finished. Maybe if I have real user comments within the doc I'll get off my arse and finish it and get it published... :-) It's currently in word doc format using the O'Reilly animal book template btw.

Your right, I had some strange behaviour in the past when working with the

mav (through bean utils) will do the datatype conversion for you, so
instead
of :

}
you can just have:

Maverick uses Commons BeanUtils to populate its beans (like the
controllers
in your case). BeanUtils does not populate any fields that do not have a
getter as well. The solution is to include the getters (like getTerm()
etc.).

[Mav-user] maverick-opt-fop with fop-0.20.5rc3a
Hi all,
When using the latest version of FOP (which is the only version that behaves
really well with my system) I came across some API changes that breaks
FopTransform from maverick-opt-fop.
1. Options are now only supported for command line operations;
2. The Avalon logger now must be set with 'driver.setLogger(log)' instead of
'MessageHandler.setScreenLogger(log)'.
I do not think 'options' is supported in any other way now; I could not find
any docs about it (though I didn't search the mailing list. As it not really
encouraged anyway, imho it's best to just discard it.
I've included a path that works with both the older (4) and the 5rc3a
versions of FOP. I do not set a logger though (but have the 5rc3a version as
a comment), as one of the methods breaks one of the versions. If not set,
the default (screen-) logger will be used.

RE: [Mav-user] reusable controllers and session objects
IMHO a sensible strategy of developping apps is to first focus on the behavoir and after that focus on performance issues. That does not mean that it is wrong to take performance issues in account in an early stage, but just do not let it overtake the main focus of your project. In my experience caching CAN make a huge difference though, especially when you have database heavy apps or - like Jeff said - object that have high initialisation costs. But ya, things like synchronisation can be killers as well. And if you use transactions for instance... be smart with them (like: is it possible to do more in the same transaction... made huge differences for us when working with OJB). And as a side note: three years ago I developed several java webapps for the AS-400 platform (JDK1.1.x). In that case object creation *was* very expensive so it did make sense to use object caching. I do not know about the current performance charactaristics of that platform. Second side note: GC can give you problems at times. A recent project where we made heavy use of JSTL could crash our server! There is/ are memory leak(s) in JSTL presumably the forEach tag. The strange thing was that in certain cases when the GC did a run the JVM ended up using more memory than before this run. On several servers (both on Win and Lunix) the memory usage could exeed gigabytes within one minute before crashing... That brings me to an example where caching makes a big difference. If you look at the performance gain Tomcat 4.1.x got compared to Tomcat 4.0.x: for our apps it was the caching of the custom tags in Tomcat 4.1.x that made the difference (about 1500 milis!). Funny thing though is that, allthough Tomcat 4.0.x is a lot slower with our JSTL intensive project than Tomcat 4.1.x, the former never crashes. This is to illustrate that, allthough caching can make a huge difference at times, it also adds complexity thus usually more bugs (can confirm that from personal experience too!) So my bottom line is to be practical. First build your app only addressing the most obvious performance issues. When all works/ is stable look at performance characteristics. IF you want to cache be aware of the added complexity, maybe using something like JCS (http://jakarta.apache.org/turbine/jcs/index.html) can help reducing that (allthough I never used it). The reason that I sometimes use singleton controllers is that those controllers do a lot of initialisation that is equal for all users and should be done only once. Eelco -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Schnitzer, Jeff Sent: maandag 31 maart 2003 23:42 To: [EMAIL PROTECTED] Subject: RE: [Mav-user] reusable controllers and session objects From: Valeri Sarantchouk [mailto:[EMAIL PROTECTED] I am trying to avoid creating new objects at every request. Is it possible to use a servlet as a (Trhowaway2) Controller? Or other reusable accross requests conroller. [...] ClientModel has 38 fields and its creation and rendering are costly operations. Plus we have at least 70 concurrent users (accessing the same view at the same time) at low periods and 350+ at high, so creating new objects for each request and passing old ones to gc doesn't look good from performace point of view. In old application, I use an object pool to get instances of Client objects for new users; and re-use Client objects found in user's session for logged-in users. Can you advise me on how to replicate an object pool with Maverick and how to reuse the same object found in session? I see you found the ControllerSingleton (and presumably FormBeanUser) controller base classes. However, are you sure of the performance characteristics of your application? Much research has gone into this subject, and the general conclusion has been that the performance cost of object creation and collection is vastly less than the performance cost of synchronization. The generational garbage collection scheme in modern JVMs is very efficient, especially with short-lived objects such as Throwaway controllers. On the other hand, the thread synchronization required for an object pool is tortuous for an application with high concurrency. Search the JBoss list for this subject - they concluded that the object pooling of EJBs is only of value when the initialization cost of a bean is very high (establishing network connections, etc). My own experience confirms this. The Sims Online player website produces zillions of objects (much, much more than a typical website) yet when maxed out under load testing I find that threads are always waiting for monitor locks. Just to give you some more idea of relative scale, a single Tomcat request produces a flurry of objects. Populating bean properties with BeanUtils produces a flurry of objects. Every JDBC driver I've ever seen produces *vast* quantities of garbage. Watching an application under a profiler is an enlightening experience -
RE: [Mav-user] reusable controllers and session objects
I prefer Velocity for simplicity and, combined with the toolbox and velocity servlet project, you can do all the stuff you can do in JSP's. With XML/XSLT you have 'know' all the stuff you're going to use in a view beforehand (just like using Velocity without the toolbox extention). Personally I like program 'dirty' at times according to the majority of Java programmers it seems. For instance, I have no problem with getting data from a database with a query that's in a view (that needs no input). Just like PhP :). I think one of the reasons that a lot of starters/ webdesigners prefer PhP and ASP/.NET over Java (at least that what I see around me) is not that it is harder, but that the Java way of programming webapps allways has to be in perfect OO style. So, even for a small site, you *have* to start with an object model. Then translate that (or the other way around) to a RDBMS. Then use something like OJB/ Hibernate/ Castor to talk to your model (and I NEVER have seen a project that did not cost a lot of time thanks to bugs in these mapping layers). Then ofcourse for every trival piece of info to show on your site you have to write an controller (hey, I wonder where the C in MVC is for... could it the controller for INPUT usage?). But then... finally we have build ourselves a nice and clean webapp. Funny thing is though, that for the smaller to average sized web projects your average PhP 'script kiddie' would have build the whole damn thing in one third of the time it took us! And we did not even start thinking about using EJB's. My point? Don't overengineer all the time. Seen it happen too often. AND it gives Java a bad name for the more 'pragmatical' programmers (read PhP/ ASP/ 4GL adepts) and managers in general. Hah that's a relieve. I just had to put this on a mailing list. I seriously have discussions at least once a week on this subject with my Java oriented collegues (who strongly disagree on this, just as they prefer Struts over Maverick as it 'does so much for you' (read: they have the form beans/ tags)), and I have to hear too often from collegues who use PhP/ ASP/ .NET/ Delphi to build applications that they think Java takes too long to develop an application. Be practical! Engineer according to the complexity of your application! Allright... I'm feeling like a scoolteacher/ know-all. Sorry about that. But I *am* wondering what other people think about this. Maybe a new thread?

Re: [Mav-user] Model doesn't get initialized?
Stephan,
To be short, the basic idea for JavaBeans is that if you have a property, it
starts with a (usually) private or protected defined field. In order to
grant access on your 'bean' to the outside world, It should have a 'getter'
and/ or a 'setter'; resp. to allow reading and writing of the field. The
standard says that a getter be of form: 'getXxx' where where the Xxx stands
for the name of the property, the first character (right after 'get') being
capitalised. An exception to 'getXxx' is the reading of a boolean value,
which should have the form 'isXxx'. This is the only exception. The setters
take form: 'setXxx'.
As '$model.name' tries to find property name, JSTL will look for the method
.getName() in your class. If it's not there it will fail (I don't know and
actually don't care about the case when your field is declared public).
Read more about it: ftp://ftp.javasoft.com/docs/beans/beans.101.pdf
Another thing to know about Java are the code conventions:
http://java.sun.com/docs/codeconv/html/CodeConventions.doc8.html
And... before doing anything else, please read at least:
http://java.sun.com/docs/books/tutorial/java/index.html.

Re: [Mav-user] server side redirects for commands
Thanks for pointing that out Jeff, You are right about the difference between redirects and forwards ofcourse, and now that I took a closer look at the code, I understand the flow. I was just looking at the friendbook example and thought that using redirects was the way to link commands in Maverik fashion. Maybe it's a good idea to adjust the friendbook example, so that the differences in usage (redirect/ forward) become clear. This is currently in the friendbook example: command name=logout controller class=org.infohazard.friendbook.ctl.Logout/ view name=loginRequired ref=loginRequired/ view name=loginFailed ref=loginFailed/ view name=success type=redirect path=welcome.m/ /command Instead something like this would clearify things: command name=logout controller class=org.infohazard.friendbook.ctl.Logout/ view name=loginRequired ref=loginRequired/ view name=loginFailed ref=loginFailed/ !-- use a redirect (HTTP 302 response) parameters set in the ControllerContext will be made available to the view in the form of request parameters Note that only string parameters will make sense -- view name=success type=redirect path=welcome.m/ !-- if you want to do a forward (server side) you can use view name=success type=document path=welcome.m/ instead. Using this will save you a client server roundtrip, and you can use arbitrary objects as request parameters, and you will have access to the model set by the last command). Note that if you access the model , and that model is a command, you create a dependency of commands and loose the freedom freely linking commands without them knowing about each other. If you use parameters in the ControllerContext, or you use a common command-neutral model, you just have a 'contract-like' dependency. -- /command I understand that you can do neat stuff with inheritance. On the other hand, I think it is nice to make commands (potentially) work together without requiring them to use a common base class. A contract (command requires certain variables to be available) couples loosely. But, hey... the nice thing about Maverik is that you can decide yourself!

Redirects are inherently client-side phenomenon; they are the result of an HTTP 302 response. Inside the server, you forward from one request to another. In fact, this is how Maverick executes JSPs (or other documents) - using the forward mechanism. Try this: view name=simpleReport type=document path=showSimpleReport.m/ This chains the first command to the second. Any params are persisted across the invocation... and if you're careful about your controller base class, you can get access to the model as well.

The current version of Maverik does a normal redirect (response.sendRedirect). Imho it would be great if Maverik would recognize that it is about to redirect to another Maverik command, and instead of doing a real redirect, call that other command. And instead of making a string copy of the objects in the context (stored like getCtx().setParam(blah, obj)) to request parameters, make (or keep) the objects available in their original form. I have got the case that I want to do a redirect to another command. For this other command I have some object (which is not of type string!) available in my first/ calling command. Right now the only way that I can expose arbitrary objects from the first command to the second command is by using session objects (or something similar), which is not *that* handy. Besides my own little problem (I already implemented the workaround), I think doing a 'server side' redirect is better because it saves a client-server roundtrip. Better because it it more efficient, and because it does not expose variables meant for internal use (which is allways the case if command1 calls command2?). Well, what do you all think?

Re: [Mav-user] Interesting MVC post
Although the refered piece makes sense I can think of some pro-MVC defences: You *never* have multiple simultaneous controls or views to worry about I would not say never. Think about portal-like functionality. Sure in the end (the complete webpage) it is just one view, but is'nt that the same for most GUI apps (one total window)? Actually I'd like to look at my webapps as a composition of elements that have their own view and can all have different controllers. BTW.. this can be done by including commands like this: c:import url=http://wholepathtoserver:port/cmd.m/ it won't work with a relative path (like c:import url=cmd.m) in Maverik (see one of my earlier posts). Your application, be it a CGI script, mod_perl handler, or even an all-in-one embedded Perl template, receives one and only one request for any one invocation, and it must generate one and only one response. Depends on how you look at it... see above. Flow of control is linear and predicatable. In the end it allways is, or is the author using random processing ;-) Desktop MVC applications are typically single-user and the in-memory model persists for a session (e.g. while the application is running). In contrast, web applications are multi-user, and in most cases, the per-user model is regenerated on each request (i.e. by restoring a user's session data from a database on each request). Mem model and single/ multiple user problems are IMHO not part of the problem that MVC solves. And the model is regenerated? What does it matter where I get the model from? There are other differences: controllers are inputs, not chunks of application code as they are portrayed in many web application frameworks; presentation elements can safely contain programming code, as long as it's presentation programming, not application programming; the model is the application state, not the application architecture, and so on. Agreed. I see this a lot in web apps that use MVC frameworks. If you want to just display something of your model, just code it in your JSP, maybe using a null command (so that you can still do nice transforms). I think Maverik does a good job (better then some other frameworks) at providing a clean architecture to solve above problems. I have come to the conclusion that most people who talk about MVC in regard to web application design don't properly understand what it is We work with design patterns to have a common basis of communication. Just consider talking about MVC in the context of web applications talking in a different accent. We globally mean the same as the traditional GUI guys, but have some small interpretation differences. I am pretty sure that most experienced programmers talking about MVC in a web context understand how the pattern works in their context. On the other hand... maybe we (programmers after the Smalltalk age?) are all just darn ignorant, and should lean from our coding ancestors ;-) (uh, sorry that was not very nice...) I think the author is right as well when he says that MVC does not solve all your problems (surprise, surprise). But it *does* give the community a nice proven method to make our webapps a bit less messy.

Re: [Mav-user] server side redirects for commands
Ok, I guess the example with the "bye" view doesn't
make much sense.I have got a working case where I use it. Check out:
http://financialtools.nl:8080/euronorm/renderq.m?collection=questionsdefinitionId=hijsbanden
It'sin dutch language,and very much in
progress (not sure for how long this site will be up, but probably at least this
week), but just answer a few questions, and you should end up with a pdf. The
site uses the following config (excerpt):
command
name="getanswer" controller
class="nl.topicus.euronorm.net.questions.ui.GetAnswerCtrl"/
view name="success"
path="questions/renderquestion.jsp"
transform
path="mlayout/bodyLayout.jsp"/
transform
path="mlayout/standardLayout.jsp"/ /view view name="simpleReport"
path="showSimpleReport.m"//command
command
name="showSimpleReport" controller
class="nl.topicus.euronorm.net.questions.ui.ShowSimpleReportCtrl"
param name="reportPath"
value="${rootdir}/WEB-INF/resources/reports"/
/controller
view name="success"
type="null"//command
In the getanswer command I store theuser
choice forlater use, and try to find the next question based on the
choice. If I am on the end of a series of questions, I am ready todisplay
a report, based on the given answers/ made choices.I just implemented an
simple approach (showSimpleReport) to rendering a report,that tries to
find a pdf file inthe repositoryfollowinging a certain naming (like,
if you answered a,b and a,I try to find [report-name]-aba.pdf). If I find
the file, I'll send it tothe servlet outputstream directely (at this
time..., will probably change this week), hence view with type
null.
So, in the above example, I have command
'getanswer' that hasthe behavouir of storing user choices and loading the
next question. If I find that I am on the end of the question chain, I want
toforward to a 'report renderer', and let this renderer do its
work.Seperation of concerns.
This works very well for me, and allthough I can do
this ina number different ways without chaining, this is what I like best.
The danger would be that you (or I for that matter) would end up making a
one-size-fits-all comand before you know it. But... if you think there's a much
better way of doing this... I'm allway opento suggestions.
Cheers,

Subject: RE: [Mav-user] server side redirects for
commands
While supporting the concept is important, I'm not personally
convinced*yet* that controller chaining has enormous merit. So far I
haven'tseen a compelling need for it in my work. Certainly in the case
of thefriendbook logout, a redirect is fully appropriate in order to
preservethe browser's ability to bookmark links. Even if you
wanted to provide a more sophisticated "bye" page instead ofjust sending the
user back to the welcome page, it seems to me thatyou're best off putting
the controller logic in the Logout class andforwarding to a normal "bye"
view.But I'm open to different views - John-Mason Shackelford seems to
beputting a lot of effort into the subject, and I'm curious to know
howthat goes :)Jeff Schnitzer[EMAIL PROTECTED]

Thanks for pointing that out Jeff, You are right about
the difference between redirects and forwards ofcourse, and now
that I took a closer look at the code, I understand the flow.I
was just looking at the friendbook example and thought that
usingredirects was the way to link commands in Maverik
fashion. Maybe it's a good idea to adjust the friendbook example, so
that the differences in usage(redirect/ forward) become clear. This
is currently in the friendbook example: command
name="logout" controller
class="org.infohazard.friendbook.ctl.Logout"/
view name="loginRequired"
ref="loginRequired"/ view
name="loginFailed" ref="loginFailed"/
view name="success" type="redirect" path="welcome.m"/
/command Instead something like this would clearify
things: command
name="logout" controller
class="org.infohazard.friendbook.ctl.Logout"/
view name="loginRequired"
ref="loginRequired"/ view
name="loginFailed" ref="loginFailed"/
!-- use a redirect (HTTP 302
response)
parameters set in the ControllerContext will be madeavailable to the
view in the form of request
parameters
Note that only string parameters will make sense
-- view name="success" type="redirect"
[Mav-user] server side redirects for commands
Hi all, Say, I have got a view like: view name=simpleReport type=redirect path=showSimpleReport.m/ (I use .m for Maverik commands). The current version of Maverik does a normal redirect (response.sendRedirect). Imho it would be great if Maverik would recognize that it is about to redirect to another Maverik command, and instead of doing a real redirect, call that other command. And instead of making a string copy of the objects in the context (stored like getCtx().setParam(blah, obj)) to request parameters, make (or keep) the objects available in their original form. I have got the case that I want to do a redirect to another command. For this other command I have some object (which is not of type string!) available in my first/ calling command. Right now the only way that I can expose arbitrary objects from the first command to the second command is by using session objects (or something similar), which is not *that* handy. Besides my own little problem (I already implemented the workaround), I think doing a 'server side' redirect is better because it saves a client-server roundtrip. Better because it it more efficient, and because it does not expose variables meant for internal use (which is allways the case if command1 calls command2?). Well, what do you all think?
