Well, I think a lot of times how much is handled by one component is a matter of the component's design. And when you have a rich set of components to choose from, you can pick more granular ones or more complex ones, depending on your disposition. And, call me crazy, but I have better things to do than write the code necessary to support a full-featured data grid. As the people at companies like Infragistics will tell you, there's a hell of a lot of functionality you can add to a data grid. Personally, I'd rather work on the specific nuances of the system I'm trying to build. For one thing the dependencies between components are not known. In the Microsoft world DB's generally have to be ODBC or not work at all. A more verifiable result is implementing the wrong version of component and you have a disaster.. I'm not quite sure what you're talking about here. Since I did Delphi development, I wasn't aware of any ODBC-specific constraints. My Achilles heel was the Borland Database Engine (BDE). But I won't go into detail about that monstrosity. Using the BDE wasn't a requirement, though, and there were alternative ways to do things. (I think Borland has axed the BDE for good, finally). Also, I wasn't trying to say that Microsoft's way of doing things is better or anything like that. I'm just saying that user interface component-oriented development (RAD, back in the day) yields productivity gains. Microsoft is the most well-known promoter of GUI components, but they're certainly not the only one. 2)Finally I would like to request (Specifically) which IDE's handle JSF today Since JSF isn't even in beta yet, you're not going to find any full-fledged IDEs that support it.

In the JSF world, this would be a component that you would use the same way -- with a simple taglib. I'm assuming that this type of functionality is what the highly anticipated JSF grid will provide in the next release of JSF (maybe Craig can extrapolate). There's an example of a much less capable, but similar, component in JSF EA4. The main difference between the component and taglib approach is that in the component world, all of this functionality would be implemented by a component/renderer pair. The component itself would be a JavaBean, so it'd have methods, properties, and events, and integrate with tools. You could even have a JavaBeans customizer that would allow you to find and connect to the data source with a wizard interface. You could also develop different renderers, so perhaps one would output HTML and another might work for a WML device. Renderers are separate from the component itself, so all of the basic properties, like the data source, wouldn't have to be changed for a new device -- only the renderer.

Problem validating form manually in DispatchAction
Hi there,
am having a problem validating a form manually using the
DynaValidatorForm.validate() function. For some reason, when validation
is carried out this way it only seems to find errors in one of the form
fields - however, if I set the validate=true property in the
struts-module-config.xml file, validation does seem to be carried out
properly, which suggests to me that I did not make a mistake in the

Struts and Tomcat JDBC Realms
Hi all ! I was woundering about using Struts in Tomcat with JDBC Realms. I found lots of topics about Strunts and Realms but using policy files and I did not find any question or topic involving struts and JDBC Reals. Does struts support the use of JDBC Realms in Tomcat ? I don't intent to use it to proctect my Actions, but to protect my jsp pages under some specific app directories. I tried to implement this running Tomcat in Security Mode but I have some SecurityExceptions in some actions. Is it common ? Could I solve it setting priviledges to struts.jar in my catalina.policy ?

You can extend RequestProcessor using a intercepting filter pattern for
preprocessing
(http://java.sun.com/blueprints/patterns/InterceptingFilter.html), so you
don't have to check the session in every jsp.

problem with forwarding to input from the method validate
Hi, I'm working with Struts 1.1 and tiles. It seems like the validate() can't forward to my tiles page when an ActionErrors occurs. Here is my struts-config.xml file : action path=/EditDossCEAction type=com.atosorigin.agrippa.web.communs.doss.EditDossCEAction scope=request name=EditDossCEForm attribute=EditDossCEForm input=page.communs.editDossCECarte validate=true forward name=edit path=page.communs.editDossCE / forward name=editCarte path=page.communs.editDossCECarte / /action When my method validate on EditDossCEForm fails it returns a non null ActionErrors and this is supposed to forward to the input page. The RequestProcessor seems to find page.communs.editDossCECarte as the input, however it fails in finding the corresponding tiles definition ( mapping.findForward(input) is null) and therefore forward me to the correct page. I solved this problem by adding this forward : forward name=page.communs.editDossCECarte path=page.communs.editDossCECarte / Was anyone aware of this problem ? Any other way to solve this ?

Parikh [mailto:[EMAIL PROTECTED] Sent: Wednesday, October 08, 2003 8:20 PM The CMP2.x spec allows declaring EJBs as local objects.

Re: Please help with this error ???en_US.errors.required???
Hi Vivien,
Take a look at your web.xml. Maybe you copied it from Struts dist and
message-resources was
already configured there. As settings in web.xml will override settings in
struts-config.xml,
classloader can't find resource to be loaded and then you get that messages.
Hope i helped you.
Kind regards,
Daniel.

I just spent Wednesday working with StrutsTestCase and UnitTestsGen and talking with Artur Hefczyc. UnitTestsGen isn't being maintained anymore, but he's more than willing to let someone else become a project member and take it over. However, the templates are currently written in Java C code statements. I spent Thursday looking at JUnitDoclet which offers all of the same functionality plus a little bit more and is actively maintained. I'd recommend you take a look at this instead. It's a bit more work to get it set up and going than UnitTestsGen, but most of that can be fixed by helping create better documentation (which is what I plan to submit to JunitDoclet after posting this message). -Mike - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

How to use tiles for Error Pages?

Re: Struts and Tomcat JDBC Realms
On 10/10/2003 01:46 PM Michel Bertrand wrote: Hi all ! I was woundering about using Struts in Tomcat with JDBC Realms. I found lots of topics about Strunts and Realms but using policy files and I did not find any question or topic involving struts and JDBC Reals. Does struts support the use of JDBC Realms in Tomcat ? I don't intent to use it to proctect my Actions, but to protect my jsp pages under some specific app directories. I tried to implement this running Tomcat in Security Mode but I have some SecurityExceptions in some actions. Is it common ? Could I solve it setting priviledges to struts.jar in my catalina.policy ? And so, does anybody implemented Struts + JDBC Realms + Tomcat ? Yes, many people do! Using a tomcat realm for authentication with standard security-constraints is not normally problematic. Setting up struts to make use of realm authorization (for roles) is child's play (as long as your database contains the roles links to the users). Just put the role attribute in the action mapping in the config. Where when are you getting these exceptions? Also, policy files don't need to come into it at all. Doing anything with priviliges to struts.jar is something I've never heard of. I think you are coming to the subject with a mindset for a different type of authentication authorization system - what you require from tomcat struts is not too complex.

Is the fact that the form.select option is ?

Processing a 'POST' from the JSP Page for an ArrayList?
I'm new to struts and so far love it, but this piece is killing me. I have a
jsp, form bean, view, action. I am ok with loading an arraylist and
embedding it into the jsp page using the iterate. Now, I want to make
changes to the table in the browser which is represented as an iterator, and
then I would like to get access to these changes back in my action class.
Currently, the action class sees the original view and not the updated view.
Here are some code snippets.
JSP -
html:form action=DeleteAwards?Method=DeleteAward
.
.
logic:iterate name=awardMasResultsForm property=awards
id=AwardMasView
.
.
TD VALIGN=MIDDLE ALIGN=LEFT class=cell
bean:write name=AwardMasView property=safAwdNameShort/
/TD
TD VALIGN=MIDDLE ALIGN=CENTER class=cell
html:checkbox name=AwardMasView property=deleteRecord
value=delete indexed=true/
/TD
Action Class -
List awards = ((AwardMasResultsForm)form).getAwards();
AwardMasView awardView = (AwardMasView)awards.get(1);
Iterator i = awards.iterator(); // this allows you to loop thru the
Arraylist
while (i.hasNext()) {
AwardMasView awardmas = (AwardMasView)i.next(); // get a copy of an
AwardMas bean from the list
System.out.println(awardmas.getSafAwardCode()); //would like to see
changed value here
System.out.println(JLB -delete + awardmas.getDeleteRecord()); //
would like to see changed value here
}
Let me know if I can offer anything else to help with this. :)

I speak as a newbie here, but I wonder if there is a way to setup struts-config.xml to expect an action that looks something like /whatever.xls, and then map that to a servlet that would create an excel file. I know that Internet Exploiter plays a lot friendlier when the mime type is actually a part of the URL (.xls in this case), so that might be a way.

RES: Struts and Tomcat JDBC Realms
Hi ! Tks for your answer. Now I understood what's happing (I hope so) ... I have a multipart/form-data and it has in its action a forward to a common text form, like: forward name=List redirect=true path=/list.do/ I believe when it reaches the redirect=true, Struts clear the request attributes and lost my user. So I have the authentication authorization problem that you advised me. Am I right ? I really need to have the parameter redirect because without it I have the MulpartIterator error. How could I workaround this situation ? Is possible to matain the user after the redirect ? And what about setting the roles for my actions ? I could simply do : action path=/upload type=com.ecommerce.album.PhotoUploadAction name=uploadForm scope=request validate=true role=user Here ? input=/album/upload.jsp Thanks in advance and regards ...

I was woundering about using Struts in Tomcat with JDBC Realms. I found lots of topics about Strunts and Realms but using policy files and I did not find any question or topic involving struts and JDBC Reals. Does struts support the use of JDBC Realms in Tomcat ? I don't intent to use it to proctect my Actions, but to protect my jsp pages under some specific app directories. I tried to implement this running Tomcat in Security Mode but I have some SecurityExceptions in some actions. Is it common ? Could I solve it setting priviledges to struts.jar in my catalina.policy ? And so, does anybody implemented Struts + JDBC Realms + Tomcat ? Yes, many people do! Using a tomcat realm for authentication with standard security-constraints is not normally problematic. Setting up struts to make use of realm authorization (for roles) is child's play (as long as your database contains the roles links to the users). Just put the role attribute in the action mapping in the config. Where when are you getting these exceptions? Also, policy files don't need to come into it at all. Doing anything with priviliges to struts.jar is something I've never heard of. I think you are coming to the subject with a mindset for a different type of authentication authorization system - what you require from tomcat struts is not too complex.

Hi Vivien,
Take a look at your web.xml. Maybe you copied it from Struts dist and
message-resources was
already configured there. As settings in web.xml will override settings in
struts-config.xml,
classloader can't find resource to be loaded and then you get that messages.

RE: Please help with this error ???en_US.errors.required???
Hi Vivien,
I think it depends on Struts version you are using. I use 1.1 and everything works
fine.
Your message-resources/ config tells Struts to look for your resources at package
org.apache.struts.webapp.tiles.dev1-1. So, you should have, for instance, this:
WEB-INF
--
|
|--- classes
--
|
|--- org/apache/struts/webapp/tiles/dev1-1
|
| - ApplicationResources.properties
If you are not using 1.1, please, upgrade to. If problem still happens, you know how
to find us.
Hope it was useful.

Not status.index you need to add a var='foo' and do:

Also, If you want 11-20 you should have begin as 11 not 10.

Re: JavaServer Faces
Thank you, Craig, for the umpteenth time for saying this. Why are so many people still talking about throwing in the Struts towel?! This is open source, is it not? Is it not the job of open source to keep ahead of the standards with great ideas that continue to make our jobs easier, more interesting, more fun, and going where no software has gone before? Is it not from open source that the standards are often based? Do we think that just because JSF is on its way into main stream that it will put an end to all we can possibly ask for as web developers? Has that ever been the case with the latest and greatest standard to come to the table? Have we not already heard of the great things the Struts developers have in mind for the future? If the new standards become all you need, then great! If not, then look to Struts and the Struts team for continuing to give you more. Thank you, Struts developers.

You should absolutely, positively plan on evaluating the use of JavaServer Faces components instead of the Struts HTML tags, and the JSTL tags instead of the corresponding bean and logic tags. Besides being standadized (which means, for example, that you can import and use *anyone's* JavaServer Faces tags, not be stuck with ones that are provided only by Struts), they are more powerful and more functional -- and they work fine in conjunction with Struts based applications. That has nothing to do with whether or not you need the other features of Struts (the core controller mechanisms, plugins, Tiles, Validator, ...) -- which can be used just fine with JavaServer Faces components as well. There is a functionality overlap in the core controller role, and for some people JavaServer Faces will be sufficient by itself. But it's our job as Struts developers to ensure that the gap continues to exist and increases; there's a lot of things required to build good web apps that are not UI components or tags, and are therefore outside the scope of JavaServer Faces and JSTL.

From my experience working with human translators this might be a
better approach. Translators like to be able to manipulate word order
and punctuation.
It is a little more code but I'll argue that it is not any less
readable. Most importantly it works with Struts links and will properly
encode the URL:
applicationResources.properties:
message.benefits=The FedEx Custom Criticalnbsp;{0}nbsp;enables ...
mainPage.shippingLinkName=Shipping Toolkit
Put this at the top of the JSP:
fmt:setBundle
basename=com.nvisia.training.struts.resources.ApplicationResources/
bean:define name=stLink scope=page
html:link action=/shipping
bean:message key=mainPage.shippingLinkName/
/html:link

In the body of the jsp:
fmt:message key=message.benefits

If we have GUIs like today's Eclipse and IntelliJ three years ago, we would have seen Struts PlugIns right away. The GUI support for Web applications is a thousand-fold better now than it was three years ago, and the Struts support rode the wave. It would also be fair to say that Struts did much to create the buzz around JSF. If the JSF came out three years ago, tools support would have been a much tougher sell, not to mention the concept of taglibs as UI components. Remember how long it was before we saw much vendor support for JSP 1.2. Times have changed. Meanwhile, as James Holmes mentioned, it's nice to see that some things don't change: open source is still leading the way, with offerings like FacesConsole and Struts-Faces, not to mention MyFaces on SourceForge.

Re: JavaServer Faces
I think the main point is that JSF is primarily about standard re-usable user interface components. It has basic controller functionality, but the UI component side of things is the real focus. Many existing frameworks -- Struts, UIX (Oracle's framework), and others, will continue to add a bunch of additional functionality but will also be able to use JSF components. That's the bottom line. And, like Ted and Craig said, smaller applications may do fine with JSF alone. At 04:03 PM 10/10/2003 -0400, you wrote: Craig R.

Now Object Pascal definitely has its lackings from a designer's view (unlike Java, it has no interface datatype rsp. interface means: COM interface, at least something with GUIDs associated), but one thing has really converted me from being a C++ addict; formerly convinced that the power lies in language constructs; and that's the inherent power of Components itself. When coding for Delphi, Compo- nents are just everywhere, and Object Pascal, as most Apple innovations, is a truly powerful OO language. You can do great things in Delphi. The downside, still, is that Components don't make you a better developer, so there's a lot of room for those quick- and-dirty hackers usually located more in the VB direction. That's the drawback of ease-of-use: you also leave room for the otherwise-illicits. But that's just the trade-off of abstraction in general. Still: Components are the future, if you like it or not, things are generally tending the more to the abstract the more complicated the under- lying problems and technologies get. It is basically inevitable, as the restrictions of the human mind necessarily require abstraction (as it can handle just up to seven different topics at a time; this is rather well-researched by other disciplines) demand for this. Now look at UML and the MDA approach that is currently the flagship of OMG. Look at both J2EE and .NET. Both technologies were clearly influenced by a book named 'Business Component Factory' released in 1997 (as I lend it to a friend, I fail to cite the authors here), but it's important nonetheless. Note that Components don't mean Delphi Components (which are basically just normal Object Pascal classes) J2EE beans, COM objects or something like this, but may deal with entire, pre-fabricated encapsu- lations of common business processes in a standard way. Components, though there's no common definition for this term, are the next step in evolution to the OO paradigm (and be honest and ask yourself - ten years ago, what did you really think about Objects and C++?) I personally remember times when I thought C was a commodity language for lusers who didn't know Assembler, held C++ for being inferior to C for the resulting .exes being bigger and everything seemed to be much more complicated and the like. I've personally seen all this before. The last time when I had just the same feeling was when JSTL was released and Java scriptlets became more or less 'banned' in terms of proper coding. This was in 2002, actually. Though I didn't like it at first (I'm a Java developer in the first place, and developers write code, wasn't it so?), I more and more acknowledged the value of the JSTL approach, ending up in recently issuing an internal rule that all scriptlet code should be banned from all View pages in favor of JSTL tags unless there's a well-justified reason for it. Now, finally ending all this endless line of aphorisms, how does it fit into the Struts and JSF picture I originally wanted to write my thoughts about? Well, to sum it up in short: today, I know, like and favor Struts above all other frameworks, and it's always hard to leave the things behind that have you have become familiar with over time for something better or more advanced. I also admit I don't know very much about JSF yet apart from the basic ideas, but I spot similarities to ASP.NET and it somewhat fits into the general picture explained above, and I somehow suspect it can't be just coincidence that the web tier seems to generally go this way. Then, Craig is the specification lead, after all, and from what I get, he says that it will be good. I have no reason to distrust him or other people in this direction or think I know better. All I can say at this stage is that Struts works fine, it solves my everyday problems in a tightly-bound- to-HTML-and-JSP way, supports a proper MVC architecture if applied right, and so I currently don't feel lacking anything. But then, I was also content with TASM 15 years ago. So, finally, JSF deserve a real chance. From a design standpoint, the overall approach of JSF seems to be superior to a tightly protocol-related imple- mentation like Struts. And whether it's a good thing or not and if it fits our needs, we may decide in about two years. Just my 2 cents, -- Chris. See.. Anyone reason that this should be kept public is to correct our understanding of what JSF is really about. ;) With the talks of JSF and it's UI/Action like capabilities it is no wonder that we think of it as a possible alternative to Struts. To use it with Struts seems to me as saying that you are using only part of the functionality of JSF. Just like your using part of the

No getter method error
Hello,
I am working on my first Struts application and I've run into a problem
with reading bean properties with the taglibs. I am using the NetBeans
IDE w/j2sdk 1.4.2 and Struts 1.1.
OK, this is what I see in my browser:
[ServletException in:/tiles/timesheet_viewer.jsp] No getter method for
property date of bean day'
Here is a chunk of the log file for the Tomcat container:

at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:107)
..
..
I've checked the struts-user archives for no getter method and a lot
of those threads were caused by problems with property names and their
corresponding accessors. I've double-checked my beans and that doesn't
seem to be the problem. My getter/setters use the same datatype, I
reference date in the tag and my getter is getDate(), I haven't
overridden my accessor methods or provided multiple accessors with
different signatures
My next step will be to take a look at RequestUtils.java:968 to see if
that provides me with a clue as to what I'm doing wrong.
Thanks for your help.

Here is the chunk from the JSP that is using the logic and bean taglibs.
week1 is a WeekBean that holds 7 DayBeans. Each DayBean then has some
properties that I would like to display:
logic:iterate name=week1 id=day
tr
tdbean:write name=day property=date//td
/tr
/logic:iterate
Note that this works fine, the toString() method of the DayBean is
called and returns the classname:
logic:iterate name=week1 id=day
tr
tdbean:write name=day//td
/tr
/logic:iterate
Next we've got my beans, I've removed some comments and cruft to make
this not manageble:
public class DatedTimesheetBean extends Vector {
/** A string to be used when this bean is displayed. */
private String date = ;
/** The total elapsed time (in seconds) of all of the items in this

Keeping Actions clean - separating actions from business model from persistence

Re: how to keep developing time as short a possible?
I think I have a good practice: Point Resin (or container) to your project where IDE is: web-app id='/' document-directory='\jasic\bPproj\bP' Cany changes to Java or JSP, you do not need to restart resin. (changes to xml files, you do). I also recomend dual mointors, resin console and browser on right; Eclipse front and center. As soon as I save an action java file, for example, I can go to left monitor w/mouse, browse the action, and new debnug messages display in resin console. Eclipse detects a change, and creates a class file. Resin detects the change, and reloads the new class. hth, .V [EMAIL PROTECTED] wrote: Hi all, I'm a J2EE developer.

Re: Keeping Actions clean - separating actions from business modelfrom persistence
I use my own framework because I don't know any better.
I am using Torque as my underlying persistence mechanism, and I have
introduced a very simple level of indirection that I think should keep me
independent of Torque in the future (I plan to swap in Hibernate or OJB on
the next app I work on). The level of indirection I introduced is
encapsulated in an object I call the DaoManager. The DaoManager is created
by a Factory class that gives me an instance of the DaoManager that works
for my particular application. Right now my Factory is creating a
DaoManager that works with Torque, but in the future it will create one that
works with Hibernate or OJB. (More info on the Factory pattern is in the
Gang of Four book, not the J2EE core patterns book someone recommended to
Sasha earlier today).
public interface IRecordDao {
public BigDecimal getId();
public void setId(BigDecimal id);
}
public abstract class DaoManager {
public abstract IRecordDao createDao(Connection conn, String daoClassName)
throws DaoException;
public abstract IRecordDao getDao(Connection conn, String daoClassName,
BigDecimal id)
throws DaoException;
public abstract void saveDao(Connection conn, IRecordDao record)
throws DaoException;
public abstract void removeDao(Connection conn, String daoClassName,
BigDecimal id)
throws DaoException;
}
As you may have noticed, this technique introduces the constraint that each
DAO must have a single numeric primary key. This is not an onerous
constraint, but may be an issue in an existing database where introducing
surrogate keys would cause problems.
I am interested in this topic so I may do some research this weekend to see
if I can think of a better way than I am currently using.
I don't know if there's a better list to discuss this type of thing... so
far this seems to be a pretty good one :) You might want to prefix your
messages with [OT] (off-topic) if you aren't sure if they are appropriate

Is it not from open source that the standards are often based? A historical note that supports what Susan (and Ted) are saying here. During the planning for what became JSTL 1.0, I was advocating the inclusion of an expression language in whatever tags we came up with, because it's a key ease-of-use feature compared to the clunkiness of expressing functional logic in XML. The strongest piece of my argument: Struts users who are used to the power of expression evaluation won't accept standard tags that don't have this functionality. :-) Now, we've got EL expressions not only in tags that understand them, but (as of JSP 2.0) EL expressions work everywhere in your page -- even in template text. And the expectations of Struts users, setting the bar pretty high, had a lot to do with that. Do we think that just because JSF is on its way into main stream that it will put an end to all we can possibly ask for as web developers? Has that ever been the case with the latest and greatest standard to come to the table? Have we not already heard of the great things the Struts developers have in mind for the future? If the new standards become all you need, then great! If not, then look to Struts and the Struts team for continuing to give you more. Thank you, Struts developers.

Does it need to have the entire dataset, or can it use an action/controller to lazy load the information from a datasource (or ejb, or web service, etc.) ?

(Doing a good view, one should know CSS, or JavaScript, etc. ) Some DAO's, such iBaits, have pagination. (and caching; also iBatis can return a List, and displaytag needs a List. How nice.) Lazyloading might help in some cases in Java, but it would not help you in SQL/Data side. SQL works on sets (set theory, right; intersections, unions, etc. Read up on Celko) and server side and client side cursors are slow and non scaleable. A given DB engine compiles the querry, selects a path, executes the path with joins, sorts the result and then send it out(this last part you want to be faster?). Some DB engines, such as pgSQL offers support for SELECT . . . LIMIT/OFFSET, so you can get to the 3rd set of 1000 records from your result set. Depending of the DB engine you use, I would ask in the DB forum, since row by row loading (what I think you wanted) is same in C lang as it would be in Java. (CLI, OCI, etc.) I do have a google like example of doing this in a good practice example open source app. bP, If data access is slow for you, I would stress test that layer/module.

RE: Keeping Actions clean - separating actions from business mode l from persistence
Hi
I have generally have done the following:
In the Action:
Use a DTO(data transfer object) to transform the ActionForm
to a business layer data object
Instantiate the business logic class of interest
Call a method on the business logic passing the DTO object
Depending on the status returned, do the appropriate actionForward
call in the action.
The action is a client of the business logic.
(in case I am not using Struts, but vanilla Servlets, the Servlet
replaces the action. the rest till applies).
In the Business logic Layer:
Apply the necessary business rules.
In case of Database persistence, call the persistence manager.
ask the persistence manager to persist the data.
The business logic shouldn't care how the data is persisted.
The standard persistence methods (create, save,
findByPrimaryKey,remove,findBy...)
are exposed to the Business Logic.
The BusinessLogic passes to the Persistence layer objects in the
businessdomain (e.g. standard data objects).
Primary Keys are encapsulated in a PK class.
In the persistence layer
store to the datastore by the method of choice (JDBC/any other
engine etc.)
do the necessary transformation on business data as required by the
persistence store.
do the reverse when retrieving data from the persistence store.
The persistence manager contains the actual classes that know how to
store and retrieve data to the persistent store.
I have always wondered where is the best place to do connection management
with the dataStore.
Should the business Logic do connectionManagement (e.g. opening a connection
(via a connection pool or otherwise)) or should that be the responsibility
of the persistence layer. Doing it in the latter(PersistenceLayer) frees up
the BusinessLayer of connection Mgt code.
If you are implementing connectionpool, the overhead is the time to return
the connection to the pool and get it back.
Thoughts are welcome!

I have a 4 tier architecture.
PRESENTATION TIER
- Struts
- Action classes
BUSINESS TIER
- Business Objects
INTEGRATION PERSISTENCE TIER
- DAO Manager
- DAOs
- Other database access mechanisms (I do some JDBC using a fancy home-grown
SQL building mechanism when dealing with particularly complex queries)
RESOURCE TIER
- Databases
In addition to the 4 tiers, my applications are separated into two parts.
One part is a reusable framework that is shared among many applications.
The second part is the actual application code that is specific to a single
application because of business rules, etc. (Even if you don't need a
reusable framework for your work, such a thing can be useful because it
allows you to do things like swap out your persistence mechanism without
disturbing your presentation code and business objects)
A single Abstract Factory (informally called Walmart) is responsible for
creating the DAO manager and the business objects in the reusable framework.
The application code must define a concrete implementation of the Abstract
Factory. This implementation must know how to create a DAO Manager that
works with the persistence mechanism being used.
So, to finally get around to answering your question, the caller of the DAO
manager does not need to know anything about the persistence mechanism used.
The DAO manager's job is to hide this information from its clients.
True, the application code does need to provide the implementation of the
Abstract Factory and an implementation of the DAO manager. However, since
the DAO manager is an abstract class, its clients can rely only on the API
of the DAO manager rather than relying on the API of the underlying
persistence mechanism. Thus the clients of the DAO manager need not know
anything about the persistence mechanism being used. So even though the
application does have to specify what persistence mechanism is used and how
to interact with that mechanism, that definition is in *one place* which
means that it can be changed if need be without impacting the business
objects.
In other words, who orchestrates the interaction of business and dao
classes? Does the action instantiate a business class and populate it
from
your ActionForm, then get a dao instance from a factory, and pass it the
business class? Or is there another pattern to this?
The exact interactions among the components of course depend on the business
rules. A typical use case is that the Action class creates a few DAOs based
on information in the request and then passes those DAOs to one of the
business objects. The business objects may in turn retrieve other DAOs,
create DAOs, or even return DAOs to the Action class for further processing
by another business object.
Well that was rather long-winded... did I answer your question or go off on
a useless tangent? ;)

Re: How To Work Out This Action Mapping?
I think you may be doing two things wrong: 1. j_security_check is a special URL. If you have a security realm defined in your web application, and authentication method specified as FORM, then the container will automatically forward any requests for protected resources to a configurable login form. This login form collects the username and password, and posts to this special URL; the post to j_security_check gets intercepted by your servlet container, which performs Container Managed Authentication - it looks for the j_username and j_password, authenticates the combination, and forwards to the originally requested resource, or to a configurable error page if the authentication fails. All this to say that you can not map an action to j_security_check. Furthermore, you can't even aggressively authenticate using CMA (Container Managed Authentication) - if you go directly to your login page (without being forwarded there by you container), and try to submit the form, you'll get an error. 2.

Re: How To Work Out This Action Mapping?
Caroline Jen wrote: Thank you for your reply. I am using container managed authentication. My problem is how to go from j_security_check back to my Struts framework. That turns out to not be your problem ... that is the container's problem. The key thing to remember is that the user should never access your login page (whatever it's URL is) directly. Instead, form-based login is triggered the first time that an unauthenticated user requests a URL that is protected by a security constraint. What happens next goes like this: (1) Unauthenticated user requests a protected resource (*NOT* the login page!) (2) Container remembers the protected resource that was requested in a private variable. (3) Container displays the login page, which must have a destination of j_security_check, and waits for the user submit. For some containers, including Tomcat, this is the one-and-only time that submitting to j_security_check will not return a 404. (4) User enters username and password, and presses the submit button. (5) Container authenticates the username and password combination. If valid, container recalls the resource saved in (2) and displays *that* to the user in response to the login submit. If this doesn't make sense, temporarily switch your app to use BASIC authentication instead, and walk through the process. The user experience will be identical except that the login page will be a popup dialog box instead of your configured login page. (Technically, it's different in one other respect -- it's the *browser* that does the remembering in step (2) and the restoring in step (5), but the user doesn't know that). The important point is that, at no time, did anyone ever submit a request to the URL of the login page, because there is no such thing when using BASIC authentication. You should pretend there is no such thing when using form based login, also; think of the login page as part of the container, not part of your app. In answer to your original question, the simplest thing to do on a login page is just use the standard HTML form element instead of the Struts html:form tag. Then, you can just say: form method=POST action=j_security_check ... /form Craig - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
