Re: how to decide how many beans to use?

[Patrick Refondini]

Check Struts Validator MultiRegistration Example.

In short what I got out of it is that you can deal with one ActionForm 
on several page thanks to :

1. the field page="..." attribute found in validation.xml form element.
2. the validator:javasecript page="..." attribute for client side 
validation if you wish.


Some code extracts to illustrate:

1. In validation.xml


  

  


  
 
 
  
 

 
  
 
 
  
 
   datePatternStrict
   ${datePattern}
 
 
  
   


2. In a first JSP



   In a second JSP




Here I use only one ActionForm (ValidatorForm) called userForm for two JSP.


may this help you ! , Patrick

Thank U for your reply and for the code details!
I used this approach to see which button was pressed and the

RE: how to decide how many beans to use?

1 actionform per page
except for wizards: 1 actionform per suite of pages that make up the wizard

There is doc around showing how to deal with Davids validation and wizards.

I'm running into a problem.  

I started out with one FormBean.  It's basically a flattened domain object.
I'm using the Dave W. Validation package and in the validation.xml, you
define
that for a particular FormBean you validate certain fields.  Different pages
need validation on different fields so using only 1 FormBean won't work.

So do you create a new FormBean for each page that needs different
validations?

thanks.

RE: ActionForm and default values

[Jesse Alexander (KADA 12)]

1 : no
2 : no

Struts allows to forward from an action to another action!!!
(should be documented in the mailing-list-archive and the dtd,...)

This way each page is a single problem (action to init, display,
action to evaluate). Struts-config.xml will tie them together.

Whether you use 1 or 2 actions for a page (earlier posts in the thread)
does not matter. I prefer 1 action and control the "flow" using the
parameter-attribute in the action-definition in struts-config.xml
In the action I just have a 
if ("init".equals(mapping.getParameter()))...
else if ("eval".equals(mapping.getParameter()))...

hope this helps

Subject: RE: ActionForm and default values


This means that in the action for the "select item" I need to get hold of
the form bean for the next page I'm going to so I can populate it.  
Two problems with this:
1. How do I get hold of the form bean?  Do I create it myself?
2. This all relies on me knowing the mappings of what page I'm going to go
to next so I can populate the form bean.  This defeats the object of having
the struts-XML file.

Below is the text from a previous email I sent.  The only reply I got was
the example didn't show 'best practises'.  In which case, what is the best
practise.


I've been through the struts-example again.  What I want to achieve is
something similar to the 'Edit user registration details'.  This
pre-populates the form with existing details.  Now the way the example does
this is to create the RegistrationForm in the action and then populate it.

>From "EditRegistrationAction.java"
// Populate the user registration form
if (form == null) {
if (servlet.getDebug() >= 1)
servlet.log(" Creating new RegistrationForm bean under key "
+ mapping.getAttribute());
form = new RegistrationForm();
if ("request".equals(mapping.getScope()))
request.setAttribute(mapping.getAttribute(), form);
else
session.setAttribute(mapping.getAttribute(), form);
} 

This seems really nasty as you are now hard-coding the name of the form
class that will be used for validation on the next page.  Any changes in
future to the "struts-config" file may well break the system.  It doesn't
feel right to have to create these forms ourselves.

Wouldn't it be more sensible to have a pre-creation method on the action of
a form that allowed allowed a the action to populate the form fields before
the page was displayed.

As long as you have the "name" attribute set correctly for the
appropriate  element of struts-config, the formbean will
always exist!  The controller servlet creates it for you.

Re: Development Environment

Trying not to cheer too much (just a satisfied user), Cygwin is a 
complete *nix environment that runs as a Windows process.  I love 
symbolic links, mounts, gcc, perl, awk and all the other tools -- 
especially the bash shell.  And I run it on every PC I use -- office and 
home.  At home I have sshd (secure shell daemon - part of OpenSSH which 
is included in Cygwin) and have no problems punching through any 
corporate firewall to not only access my home PC, but (with the help of 
TightVNC) bring up my home desktop remotely.

I like to think of Cygwin as a way of getting to me the most powerful 
open source tools on the planet while still letting me use all of the 
GUI tools I want when I have need for something more visual...

RE: dynamic input fields

[Press, Michael]

I just did this.  I based my solution on the Dynamic Properties solution by
Kevin Wang
(http://www.mail-archive.com/struts-user@jakarta.apache.org/msg01374.html),
but I needed to do it without modifying/extending Struts itself.

I created a BaseActionForm that my ActionForms extend.  The Base class has a
method that takes the HTTP request, and for each parameter in the request
that doesn't have a setter method in the form (determined via reflection),
it adds it to a hashtable.  It also provides methods to retrieve the
hashtable or one named dynamic property.

Then, my Action classes first call form.setDynamicMethods(request), and then
they can retrieve the parameters from the known getter methods or from
getDynamicProperty() or getDynamicProperties().

There's a slight performance penalty in that the request parameters are
traversed twice (once by Struts and once by me), but it's important to me
(and my customers ;-)to be able to upgrade Struts without re-integrating my
customizations.

IntelliJ IDEA is the coolest thing since sliced bread!

Despite having a JBuilder license, I used to spend most of my code editing
time in TextPad because it was quick. I recently tried IntelliJ and have
completely switched over. It has some really cool features like Refactorings
(try them and see), CVS and Ant integration, remote debugging, and lots
more. IntelliJ is pure Java and high quality (doesn't crash), but it can get
a little slow on occasion. Very highly recommended.

RE: dynamic input fields

[SHURTLEFF,ROBERT (HP-FtCollins,ex1)]

You have to do it all yourself.

I have several of these.

In my Action, I manually extract what comes in and put them in a Map.

Struts by itself does not handle this situation nor table data very well.

However, I believe that there are some other addons that do the table piece.
Not sure about the dynamic piece.

RE: EJB = bad = MS.net

[Thinh Doan]

I vote to keep this discussion going on here since 1) I don't want to
subscribe to another mailing list, and 2) it's a "natural" progression for
me to follow the MVC (Struts) framework/mindset.  There are topics related
to Struts here that I can't afford to read them all, perhaps EJBs could be
one topic for those who are not interested in this subject.

About Ghoot's point that we need to pick the right technology for the right
application/requirements, I'd totally agree.  And I'm relying on this type
of discussions to help me make that initial decision, provided it's factual
and objective.  If everyone says technology XYZ should be avoided because
1)... 2)..., don't go there, why would I waste time considering or
evaluating it?

So many thanks to those who have contributed to this thread.

"a dvice" on this board


I'm not sure it is entirely off-topic, Alex. Many people are concerned, and
rightly so, about application of technologies and design patterns in the
development of systems which are also utilizing Struts. Sometimes the use of
a framework like Struts can result in confusion by less enlightened ones
than yourself about how to 'hook-up' the rest of the system. I've seen
several posts now by Ted Husted that talk about the proper allocation of
responsibilities to Action classes v. "business delegates" which interact
with the model. Meaningful advice about patterns and technologies can help
people who are searching for proven solutions. Unfortunately, the thread
went a bit astray even as it started because of the character of the
comments.

BTW, as for mapping "500 data tables to 500 entity beans" being an "idiotic
architecture", I went to an IBM WebSphere Commerce Suite course last month
and learned that the product has 300 tables, nearly all of which are mapped
by CMP entity beans. There are almost no session beans in the design. And
they don't use container managed transactions. Every unit of work started by
a web hit is wrapped in a JTA user transaction by the web app front
controller and the transaction includes the response generation. Not quite
the architecture I would have expected. Can't speak to any of the -ilities
of this design. But just goes to show, I think, that there are plenty of
ways to tackle the problem.

As for off-topic discussions, I would have expected you to flame the "Which
development environment" thread a little more vigorously than this one. But
maybe what is irrelevant, frivolous, ignorant, or off-topic is a matter of
personal opinion?

struts with div tag

[Yu, Yanhui]

Hi,

I have an interesting problem in the past two days and have not been able to
solve it, I am seeking help from you:
I have a form with three tables stacked vertically on top of each other.
The table in the middle would hold dynamically many rows of data.  I am
thinking using div tag to enclose this middle table so the user can still
see the first and last table on the same page without scrolling the page up
and down.  Since the middle table has the div tag so the user can scroll up
and down on that table.  But as soon as I add the  tag, the middle
table would show many blank lines on top of the real data-rows.  Any ideas?

Thanks,
Yanhui Yu

Hi, I encountered a rather interesting problem over
the past few days.  When I have nocache set in the
web.xml, I am not able to generate PDF from the
servlet in the IE browser.  I believe that this is due
to the specifics of IE.

As soon as I take the nocache out from the web.xml,
the streaming of PDF to the IE works fine.  

Now, the question is can I somehow disable the nocache
features for a specific page?  (ie the page that is
used to generate the dynamic PDF)

Thanks,

I agree. Doing EJBs is bad on many levels and creates more problems. 
Avoid EJB if you want to stay in Java.

Alternative is to just use Struts + TomCat + RowSet (or DAO if you are 
doing something simple or small) and done. This is the sweet spot. MVC 
is all you need.

Alternative, do EJBs and your organization WILL switch to MS .NET on the

EJBs are for newbies. (If you need middleware (very rare) use SOAP)

On husted.com, Ted Husted wrote:
Do not check for null ActionForm beans in your Actions
If an Action expects an ActionForm bean, then its API contact with the
ActionMappings should require that this bean, or a subclass, be named in the
ActionMapping. The Actions contact wit the controller is that it will always
instantiate the bean before the Action is called. If either contact is
broken, the application should expose a null pointer exception so that the
problem is fixed and the misunderstanding resolved. Whether an Action
expects an ActionForm bean should be specified in its Javadoc.

Now I'm wondering if 'contact' was a type and what he meant was 'contract',
that is, in the sense of an API contract or implied constrain,
pre-condition.

(You out there Ted?)

Anyway, this seems like a good idea. I'm always complaining that exceptions
are often overused or misused in Java, and this seems like a good use: let
the exception raise havoc, in order to inform you of a really exceptional
condition, and one that should be exposed if it exists.

I don't think there is a way to set different value for the submit's value

How to name, package Actions

[Molitor, Stephen]

I have two best-practices questions:

FIRST QUESTION:  How best to name Action classes?  Do you name an action
after the button that initiates it, the place it comes from?  Or, do you
name the action for what it goes to?  Or, for what the action does -- but
sometimes it's not so simple.  For example, imagine this scenario:

1.  From the 'Show Widget' page, user selects the 'Delete Widget' button.
2.  action1 is performed, which forwards to the 'Are You Sure?' page.
4.  User selects 'yes'
5.  action2 is performed, which physically deletes the record.

What are good names for action1 and action2?  If you name your actions for
the user gestures that trigger them, you might have this:

action1:  DeleteWidgetAction
action2:  YesReallyDeleteTheWidgetAction

Naming the first action 'DeleteWidgetAction' seems to make sense, since its
triggered by clicking on the 'Delete Widget' button.  But, then it's hard to
come up with a name for action2.  Plus, action1's name is misleading,
because it doesn't actually perform the delete.  OK, lets try naming the
actions after what they really do:

action1:  ConfirmDeleteWidgetAction
action2:  DeleteWidgetAction

This seems a bit better, but action1's name is a bit awkward.  

In one way, Actions are like events triggered by clicking on something.  In
another sense, Actions represent the transition between two states, the
previous and next pages.  Or, they're just reusable commands.  This last
view is probably the most accurate, but I find it hard to come up with names
for commands.  Any heuristices or guidelines for naming actions would be
appreciated.


SECOND QUESTION:
How best to package Actions and ActionForms?  It's no problem for small
apps, but becomes a problem for larger ones.  Do you have lots of small
packages?  Do you put ActionForms and Actions in the same package?   Or,
separate sub-packages for Actions and ActionForms?  

Lets say I working for an application called 'MyApp', for a company called
'Acme', and that there's a set of pages in the app dealing with user
registration.  Here are some packaging options:

OPTION 1 - By app --> sub-app
com.acme.myapp.registration.Form1
com.acme.myapp.registration.Form2
com.acme.myapp.registration.Action1
com.acme.myapp.registration.Action2

OPTION 2 - By app --> sub-app --> object type
com.acme.myapp.registration.forms.Form1
com.acme.myapp.registration.forms.Form2
com.acme.myapp.registration.actions.Action1
com.acme.myapp.registration.actions.Action2

OPTION 3 - By app --> object type --> sub-app
com.acme.myapp.forms.registration.Form1
com.acme.myapp.forms.registration.Form2
com.acme.myapp.actions.registration.Action1
com.acme.myapp.actions.registration.Action2

(I don't care for option 3.)

Any thoughts, other schemes?  I presume one would a matching sub-directory
structure for the JSP's.


Thanks!

Is there any one who may help me to figure out how to use  rag

errors are:

javax.servlet.ServletException: BeanUtils.populate

Root Cause:
java.lang.IllegalArgumentException: argument type mismatch

my JSP file has:



and my ActionForm has:

RE: Struts design question about maintenance screens

[Jakkampudi, ChandraseKhar]

Another drawback of Option 1 is that if your jsp's change frequently (adding
fields in the form, different formatting etc.) having two jsp's requires you
to update two files. This is not a problem in itself but it might make for
more difficult maintenance because you might make changes on one jsp but
forget the other.
Just another thing to consider when you make your design choice.

Option 3 sounds attractive. Thanks for the idea, Emaho.

Please respond to

Struts Users

Mailing List

 

 




There are a number of ways to achieve this, and again (!) it's about
choice, although I must say this can be confusing for newbie  (and
experienced!) struts users.

1. 2 Actions, 1 for 'pre' and 1 for 'post' processing
2. An 'action' parameter, with switch behaviour in the action class
3. 'isVirgin()' extension to the Action Form.

Option 3 is basically an added method to the ActionForm class that allows
the Action to determine if 'pre' or 'post' processing the form, without the
need for an 'action' parameter. Consider the following in the Action class,
where 'sf' refers to the instance of the form:

// determine if pre-processing, and if so continue on to the View
if (sf.isVirgin())
return
mapping.findForward(ChikiConstants.ACTION_FORWARD_SUCCESS);

// getting this far indicates post-processing...

/**
 * Determines if pre or post processing the form.
 * Criteria being null indicates pre-processing.
 *
 * @return true if pre-processing the form
 */
public boolean isVirgin () {
return ( (criteria == null) );
}

The 'isVirgin' method returns true if 'pre' processing the form, and false
if 'post' processing.

Option 1 gives good seperation, but can lead to an unneccesary
proliferation of Action classes in large apps
Option 2 achieves the same, but can lead to 'messy' Actions
Option 3 needs additional logic in the form, but allows pre and post
processing in the one Action - however, this doesn't extend as far as
seperate actions and action parameters when you need to do more than just
pre and post processing.

In our applications we have used all 3 at various times. We tend to use
option 3 when we just need the split between pre and post processing, eg a
Search or Login action. In more complex sceanrio's we tend to use option 1
or 2.

Try to determine which best fits your scenario. Depending on your context,
one solution may be better than the other, but this will not be true across
the board for all scenarios. Think through your real needs before choosing
the solution.

With regards to your exact scenario, we developed option 3 as a solution to
this very situation, so I would suggest option 3 might be best suited,
although you will ultimately have to decide ! Having developed option 3 and
implemented it, we have found it to be the most effective way of getting
around this. As I previously stated, option 1 and 2 come into their own in
other situations.

Hope this helps - if you need any more detail let me know,

Ghoot

RE: Struts vs Template Engine or Both

[Phase Communcations]

If find it interesting that the argument of placing scriptlets into a jsp
page is reason enough not to use them. Has anyone heard of custom tags. If
you want to avoid placing scriptlets in your page then develop a tag that
handles the data. I have been developing in jsp for a year and a half and
have NEVER put a scriptlet in a page. I have found struts/jsp to be a great
platform for separating view and control. The other thing is let's not get
religious about MVC. There may, rarely (if ever), be an instance where
someone needs to grab some data form a view (hisss). But I have seen SQL
tags and other such tag-libs that might do someone some good who is working
on a project and wants to get a portion of it done and working. Then we can
go back and put things the way they should be (MVC). I have worked in
production enivronments where you need to get it done yesterday and you have
to write sloppy code to get it done. That's life. It's nice to have options.
I see that JSP provides that. Struts allows for the flexibility. This is a
good thing.

I am not getting in to a holy war over struts/jsp versus struts/velocity. I
am just saying. Stop with the scriptlet argument its not that major of a
point and your designers don't have to see a stitch of it and they shouldn't
have to use it if you understand what you are developing with and how best
to use it.

We are working on integrating Velocity tightly with Struts. A prototype
with several simple application examples is available here:

http://husted.com/struts/resources/velstruts.zip

This contains a *.war file. Put the *.war into the webapps directory of
a Tomcat installation and restart. Then point your browser at
http://server:port/velstruts/ to see and try the examples. We are
currently in the process of redesigning the API and putting together
documentation. I hope for a first release version in the comming weeks.
I will announce major changes on this list.

Regarding your questions:

- As you can see in the examples, JSPs and Velocity templates can be
used in the same application. No restrictions.

- Regarding the learning curve of Velocity. The language is
really simple. Less than 10 directives. Velocity templates don't
allow Java scriptlet. If you have been relying on that feature
a lot, existing applications might need some redesign to be able
to use Velocity. Velocity really enforces a clear separation between
view and control.

- Regarding performance: Many users have reported that they
obtain about the same performance with JSP and Velocity (it really
depends on the types of templates). So, performance it not an
argument for or against one of the two technologies. We plan to do
some more performance tests with a first release version.

Yes, I got around the same problem by upgrading from Tomcat 3.2 to 4.0.  The
release notes for Struts said that it should work with 3.2, but it didn't.
I was a little alarmed that the example did not work. I think I saw a
pending bug report somewhere.

Subject: pre-compiling JSPs w/ Struts


I'd like to go ahead and voice some thanks to anyone who can help me out on
this...

Ok, I know that this has hit the list a few times before, and I've peered
into the mail-list archive (as well as my crystal ball) to figure this one
out, but I was wondering if someone could give me a little validation:

We already have an existing application built on the Struts framework (works
great, woo-hoo!), but now we'd like to precompile the JSPs for production
purposes (current production uses non-precompiled JSPs).  However, we'd like
to retain the ability to use non-precompiled JSPs for development purposes,
QA, etc.  I understand how to precompile the JSPs, and they should reside (I
think) in the WEB-INF/classes folder.

As I understand it, to enable precompilation with struts, one has to define
a servlet-mapping (for each JSP class) in the web.xml file, and then refer
to these mappings'  values in your  tags within the
struts-config.xml.

To switch between precompiled and non-precompiled JSPs, one would swap out
web.xml files (one w/ servlet mappings, another without), and switch your
build target to package either JSP pages or their corresponding compiled
classes.

So, here's an example (as I see it) of using a precompiled JSP servlet
mapping w/ a Struts forward (let me know if this is wrong):

RE: html:submit button

[Maturo, Larry]

Hi Konstantina,

Since you haven't supplied enough details, I'll assume that
you have a table, and each row contains info on one product,
plus two buttons, one for displaying info and one for do
something with the product.

In this case you then make each button look like an array, in 
your form bean, declare something like:

private int editIndex = -1;
private int infoIndex = -1;
private String editString = "";
private String infoString = "";

public String getEditString(int index) {
return editString;
}

public final void setEditString(int index, String editString){
this.editString = editString;
this.editIndex = index;
}

   public int getEditIndex () {
return editIndex;
   }

public String getInfoString(int index) {
return infoString;
}

   public final void setInfoString(int index, String infoString){
this.infoString = infoString;
this.infoIndex = index;
   }

   public int getInfoIndex() {
   return infoIndex;
   }

In your jsp, inside your iterate, you woud use:

 
 

When submitted you can use getInfoString and getEditString
to see which button was pressed (the pressed button will have
a value other than "") and then use the appropriate get index
to see which item was selected.

Implement HTTP and HTTPS in a safe, flexible, and easily maintainable manner

[Niall Pemberton]

This gives an example of how to integrate SSL into a Web App, using Struts
as an example.

The method call can take place anywhere, but always appears to be 
remote. That could be many remote machines though. Location independence

pre-compiling JSPs w/ Struts

[Joseph Barefoot]

I'd like to go ahead and voice some thanks to anyone who can help me out on
this...

Ok, I know that this has hit the list a few times before, and I've peered
into the mail-list archive (as well as my crystal ball) to figure this one
out, but I was wondering if someone could give me a little validation:

We already have an existing application built on the Struts framework (works
great, woo-hoo!), but now we'd like to precompile the JSPs for production
purposes (current production uses non-precompiled JSPs).  However, we'd like
to retain the ability to use non-precompiled JSPs for development purposes,
QA, etc.  I understand how to precompile the JSPs, and they should reside (I
think) in the WEB-INF/classes folder.

As I understand it, to enable precompilation with struts, one has to define
a servlet-mapping (for each JSP class) in the web.xml file, and then refer
to these mappings'  values in your  tags within the
struts-config.xml.

To switch between precompiled and non-precompiled JSPs, one would swap out
web.xml files (one w/ servlet mappings, another without), and switch your
build target to package either JSP pages or their corresponding compiled
classes.

So, here's an example (as I see it) of using a precompiled JSP servlet
mapping w/ a Struts forward (let me know if this is wrong):

RE: EJB = bad = MS.net - worrisome flow of ignorant off-topic "a dvice" on this board

[Cakalic, James]

I'm not sure it is entirely off-topic, Alex. Many people are concerned, and
rightly so, about application of technologies and design patterns in the
development of systems which are also utilizing Struts. Sometimes the use of
a framework like Struts can result in confusion by less enlightened ones
than yourself about how to 'hook-up' the rest of the system. I've seen
several posts now by Ted Husted that talk about the proper allocation of
responsibilities to Action classes v. "business delegates" which interact
with the model. Meaningful advice about patterns and technologies can help
people who are searching for proven solutions. Unfortunately, the thread
went a bit astray even as it started because of the character of the
comments.

BTW, as for mapping "500 data tables to 500 entity beans" being an "idiotic
architecture", I went to an IBM WebSphere Commerce Suite course last month
and learned that the product has 300 tables, nearly all of which are mapped
by CMP entity beans. There are almost no session beans in the design. And
they don't use container managed transactions. Every unit of work started by
a web hit is wrapped in a JTA user transaction by the web app front
controller and the transaction includes the response generation. Not quite
the architecture I would have expected. Can't speak to any of the -ilities
of this design. But just goes to show, I think, that there are plenty of
ways to tackle the problem.

As for off-topic discussions, I would have expected you to flame the "Which
development environment" thread a little more vigorously than this one. But
maybe what is irrelevant, frivolous, ignorant, or off-topic is a matter of
personal opinion?

Re: tag

[Eddie Bush]

The validate function can be implemented to validate your form input.  If
you find erros, you can put those errors into an ActionErrors object and
then return them.  The 'best practice' approach would probably be to have
your validation encapsulated in a 'utility bean' that you could instantiate
to make calls against (that's how I am doing mine anyway).  However, for a
small project you could easily include all of you login right in validate.
There is a good example of doing this in the struts documentation, and I
believe the users guide covers the topic quite well too.  If you haven't
already looked them over, you really should.

How to best use the validation mechanisms provided by struts is quite a
debated issue =)

No matter where/how you implement your logic to validate your form, you'll
want to create an ActionErrors instance and add ActionError instances to it,
and finally return the ActionErrors object.  Very simply:

ActionErrors actionErrors = new ActionErrors();

... then, assuming they don't specify a file - and assuming it is a required
field.

actionErrors.add("File", new ActionError("error.file.required"));

and then at the end of your perform, don't forget to:

return actionErrors;

The text passed to the ActionError constructor ("error.file.required") needs
to be specified in your application resources file.

HTH,

Eddie

RE: Code To Update DB With Transactions (was RE: EJB = bad = MS.net)

[Cakalic, James]

In short, I think the catch is that this style of dealing with transactions
distributes knowledge and responsibility throughout the application, relying
on a coding convention to implement a system policy. Better to encapsulate
that policy so that it can be globally enforced.

An EJB container brings three benefits that immediately come to mind. First
is that it provides that global implementation of transaction management.
All calls to enterprise beans can be performed in the context of a
transaction which the container ensures is either committed or rolledback as
appropriate. Regardless of how convoluted the path might get through code
contributed by any number of developers, the transaction management is
applied globally and consistently. Second, the transaction management is
declarative. I could write all day about it but it's one of those things
that, until you've experienced it, you really don't appreciate it. Sort of
like the first time you use a configurable logging package instead of
System.out. Third, the container can bring resources beyond simply database
connections into the scope of the transaction. For example, JMS-compliant
messaging systems like MQSeries and SwiftMQ can now be incorporated in a
transaction along with database activities.

Even if you don't use EJBs, I would think that you would want to seriously
consider the encapsulation of your transaction management. For example,
suppose you had something like this:

abstract public class TransactionalCommand implements Serializable {
protected Connection _conn;
public void setConnection(Connection conn) {
_conn = conn;
}
protected Connection getConnection() {
return _conn;
}

abstract void performExecute() throws Exception;
abstract public boolean isReadyToExecute();

public void execute() throws Exception {
if (isReadyToExecute() == false) {
// subclass determined not ready to execute
throw new Exception("Not ready to execute!");
}
new TransactionExecutive().executeCommand(this);
}
}

public class TransactionExecutive {
public void executeCommand(TransactionalCommand cmd) throws Exception {
Connection conn = null;
try {
conn = DbUtils.getConnectionWithTransaction(...);
cmd.setConnection(conn);
cmd.execute();
DBUtils.commit(conn);
} catch (Exception e) {
// some command failure
DBUtils.backout(conn);
// maybe provide some global logging?
throw e;
} finally {
DBUtils.releaseConnection(conn);
}
}
}

Then you could encapsulate your update logic like this:

public class AddUserCmd extends TransactionalCommand {
// could have setters for input properties
// could have getters for output properties

public void performExecute() throws Exception {
DBUserValidator.saveToDb(getConnection());
DBAuthorisationValidator.saveToDb(getConnection());
}
}

And you'd invoke it, perhaps even from your Action like this:

AddUserCmd cmd = new AddUserCmd();
// some input parameters?
try {
cmd.execute();
} catch (Exception e) {
// something went wrong so handle it
}

Note that the "simpler" part is really the implementation of the AddUserCmd
class and the usage pattern for executing the business logic. Now that
you've encapsulated the transaction management within the
TransactionExecutive and provided an infrastructure for wrapping your
transaction business logic so that it can be handed in to the executive, you
don't have to think about getting connections, commit and rollback, or
disposing of connections. That code exists in one place providing a global
policy implementation. You are now free to think about how to implement the
business logic of what you are trying to accomplish without being distracted
by the mechanics of low level details like transaction handling.

By the way, did you notice that TransactionalCommand implements
Serializable? Now, if you wanted, you could serialize your commands, maybe
queueing them for asynchronous or batched execution. Maybe you find that you
_would_ like to distribute your system physically. Perhaps putting the web
server on one system and the database on another. Perhaps, not saying
definitely so, but perhaps there might be benefit then, performance,
administrative, or otherwise, to having a separate process running on the
database system that is the target for your commands. You could change the
TransactionalCommand.execute method to say, open a socket to your server
process and serialize the command to it. The server process could
deserialize it and use the TransactionExecutive to execute the command. All
without changing any of the rest of the implementation of your application.

This design is really quite similar to what my team is currently doing. But
instead of our own command framework, we'r

RE: EJB = bad = MS.net - worrisome flow of ignorant off-topic "advice" on this board

[Esterkin, Alex]

I hope not many enterprise applications are built using this ignorant
'advice'.  IBM argued against EJBs up until recently because of countless
deficiencies in EJB container implementation in WebSphere 3.5.*.  Since
WebSphere 4.0 introduction, they have clearly warmed up to using EJBs in
their "best practices" white papers. 

As any other technology, EJBs can be abused. If one mapped a fully
normalized DB schema consisting of 500 data tables to 500 entity beans, this
would be an idiotic architecture. In any case, this has nothing to do with
MVC or Struts.

I suggest members of this list stick to the main topic of discussion -
Struts.  Struts has nothing to do with EJBs.  In a properly designed
application, EJBs, DAOs or any other persistence related components
shouldn't be accessed directly from presentation elements and components,
such as JSP tags.  

Sticking closer to the topic of this list will allow to reduce the flow of
postings to more reasonable levels.

Best regards,

   Alex Esterkin

I agree. Doing EJBs is bad on many levels and creates more problems. 
Avoid EJB if you want to stay in Java.

Alternative is to just use Struts + TomCat + RowSet (or DAO if you are 
doing something simple or small) and done. This is the sweet spot. MVC 
is all you need.

Alternative, do EJBs and your organization WILL switch to MS .NET on the 
next project, leave J2EE, and you have to learn VB.net.

EJBs are for newbies. (If you need middleware (very rare) use SOAP)

RE: (StrutsNewUser) - Accessing datasource in an initialisation servlet.

[Christopher . Falling]

Dave, which version of struts are you using?

Here is how I access my datasource with a nightly build from ~ Jan 20.

  

  
  
  
  
  
  
  
  

  

This is how I access it

Subclass of org.apache.struts.action.ActionServlet

java.sql.Connection conn = null;
javax.sql.DataSource dataSource = 
(javax.sql.DataSource)
this.getServletContext().getAttribute(org.apache.struts.action.Action.DATA_S
OURCE_KEY);
try {
  conn = dataSource.getConnection();
} catch (Exception e) {
...
}


In my action classes I pull the database from the servlet

try {
  dataSource = (javax.sql.DataSource)
servlet.getServletContext().getAttribute(Action.DATA_SOURCE_KEY);
  myConnection = dataSource.getConnection();
  ...
} catch ...

Notice that the key is the org.apache.struts.action.Action.DATA_SOURCE_KEY
which
is the default key assigned to the datasource if you don't set the key
property.
The default is fine for my app which is only using one datasource.  If you
need
multiple you need to define the key in the data-source node of the XML.

Hope this helps

Chris

There are a number of ways to achieve this, and again (!) it's about
choice, although I must say this can be confusing for newbie  (and
experienced!) struts users.

1. 2 Actions, 1 for 'pre' and 1 for 'post' processing
2. An 'action' parameter, with switch behaviour in the action class
3. 'isVirgin()' extension to the Action Form.

Option 3 is basically an added method to the ActionForm class that allows
the Action to determine if 'pre' or 'post' processing the form, without the
need for an 'action' parameter. Consider the following in the Action class,
where 'sf' refers to the instance of the form:

// determine if pre-processing, and if so continue on to the View
if (sf.isVirgin())
return
mapping.findForward(ChikiConstants.ACTION_FORWARD_SUCCESS);

// getting this far indicates post-processing...

/**
 * Determines if pre or post processing the form.
 * Criteria being null indicates pre-processing.
 *
 * @return true if pre-processing the form
 */
public boolean isVirgin () {
return ( (criteria == null) );
}

The 'isVirgin' method returns true if 'pre' processing the form, and false
if 'post' processing.

Option 1 gives good seperation, but can lead to an unneccesary
proliferation of Action classes in large apps
Option 2 achieves the same, but can lead to 'messy' Actions
Option 3 needs additional logic in the form, but allows pre and post
processing in the one Action - however, this doesn't extend as far as
seperate actions and action parameters when you need to do more than just
pre and post processing.

In our applications we have used all 3 at various times. We tend to use
option 3 when we just need the split between pre and post processing, eg a
Search or Login action. In more complex sceanrio's we tend to use option 1
or 2.

Try to determine which best fits your scenario. Depending on your context,
one solution may be better than the other, but this will not be true across
the board for all scenarios. Think through your real needs before choosing
the solution.

With regards to your exact scenario, we developed option 3 as a solution to
this very situation, so I would suggest option 3 might be best suited,
although you will ultimately have to decide ! Having developed option 3 and
implemented it, we have found it to be the most effective way of getting
around this. As I previously stated, option 1 and 2 come into their own in
other situations.

Hope this helps - if you need any more detail let me know,

Ghoot

RE: Development Environment

[Kanoza, Douglas (NCI)]

Visual SlickEdit (http://www.slickedit.com/home.php).  In my experience,
every IDE I've ever worked with (JBuilder, JDeveloper, Visual Café) forces
you to do things their way, which is usually not the way I want to do it.
Plus, they're expensive, take up a lot of disk space, and are usually memory
hogs.

RE: Struts design question about maintenance screens

[Emaho, Ghoot]

There are a number of ways to achieve this, and again (!) it's about choice, although 
I must say this can be confusing for newbie  (and experienced!) struts users.

1. 2 Actions, 1 for 'pre' and 1 for 'post' processing
2. An 'action' parameter, with switch behaviour in the action class
3. 'isVirgin()' extension to the Action Form.

Option 3 is basically an added method to the ActionForm class that allows the Action 
to determine if 'pre' or 'post' processing the form, without the need for an 'action' 
parameter. Consider the following in the Action class, where 'sf' refers to the 
instance of the form:

// determine if pre-processing, and if so continue on to the View
if (sf.isVirgin())
return mapping.findForward(ChikiConstants.ACTION_FORWARD_SUCCESS);

// getting this far indicates post-processing...

/**
 * Determines if pre or post processing the form.
 * Criteria being null indicates pre-processing.
 *
 * @return true if pre-processing the form  
 */
public boolean isVirgin () {
return ( (criteria == null) );
}

The 'isVirgin' method returns true if 'pre' processing the form, and false if 'post' 
processing.

Option 1 gives good seperation, but can lead to an unneccesary proliferation of Action 
classes in large apps
Option 2 achieves the same, but can lead to 'messy' Actions
Option 3 needs additional logic in the form, but allows pre and post processing in the 
one Action - however, this doesn't extend as far as seperate actions and action 
parameters when you need to do more than just pre and post processing.

In our applications we have used all 3 at various times. We tend to use option 3 when 
we just need the split between pre and post processing, eg a Search or Login action. 
In more complex sceanrio's we tend to use option 1 or 2.

Try to determine which best fits your scenario. Depending on your context, one 
solution may be better than the other, but this will not be true across the board for 
all scenarios. Think through your real needs before choosing the solution.

With regards to your exact scenario, we developed option 3 as a solution to this very 
situation, so I would suggest option 3 might be best suited, although you will 
ultimately have to decide ! Having developed option 3 and implemented it, we have 
found it to be the most effective way of getting around this. As I previously stated, 
option 1 and 2 come into their own in other situations.

Hope this helps - if you need any more detail let me know,

Ghoot

RE: Struts design question about maintenance screens

[theron . kousek]

thanks Simon:

With all do respect to the other method (ie, parameters), I tend to favor
your approach.I have just completed a maintenance screen by having a
combined action and I don't like the if-else's and the action file is huge.
By splitting it, I can re-use the LoadFormAction in other areas as well as
the SaveAction and not have both operations (load and save) tightly coupled
as I don't feel they should be tightly coupled.The only drawback I see
with this favorable approach is more source files but these source files
will be smaller and more maintanable/straight-forward I believe.

Before I went with this approach, I just wanted to hear how others felt
about this approach.

thanks for your input.

Theron

In reference to having two actions (create and update) instead of one
combined action, this is exactly what I have done. While the struts-example
uses a parameter, I personally prefer not to take that route.

I have simplified my code/JSPs by having each do only one thing (good OO)
at the slight expense of increasing the number of Java classes and JSPs.

Using 2 JSP instead of 1 might seem like duplication, but there isn't that
much and each JSP is much easier to read/maintain than the single JSP that
is trying to pretend it's two. The extra action classes are also not a big
deal as I move more and more logic out of the action classes themselves.

Just my thoughts.

Is there a way to have display only properties on a form? For example, I
want to display UserID as non-editable field and address as editable. I
cannot use the "disabled" attribute on text tag because these values are not
passed to the server and I need the userID to edit proper values.

I am doing something weird like using both 



The text tag is used to display the data and the hidden variable passes the
data to the action form. Seems kludey but it works. Is there a better way.
Maybe a tag that can store additional information about a form that is not
an "input" field.

Re: form validation

[keithBacon]

There are various solutions.
I put a hidden variable on my form (& in the formBean) with the form name in
it.
If it's not there I know not to validate the form data.
Some people have 2 Actions & Action classes for this but I fear that would lead
to too much code duplication.
However some of my Action classes are getting a bit big & unwieldy.

RE: Struts design question about maintenance screens

[Jakkampudi, ChandraseKhar]

You dont need two actions. You can use an 'action' parameter to decide which
action you are performing. 
On your html:link add a parameter action="view" 
and on the submit action="add" or action="edit" depending on  what you are
doing.
In your action, you can have if statements that perform different functions
base on what you are doing.

There is an example in the struts docs that explains this. (Cant find it
now. you have to search for it)

Subject: Struts design question about maintenance screens



Hi Folks:

thanks to your help, you indicated that the Action should preload form
values on a maintenance form.   This works great.

I have an Action object that allows maintenance on a table (call it table
A).   This action object handles "preloading of data"
as well as the actual "updating of data" (Add/Edit/View).

Another question I have:
- The action object gets kind of "kludgey" in how I have to keep track of
"whether I am preloading data (called from a html:link)" or whether I am
"Applying" the data (called from the form Submit).
Is it "overkill" if I create 2 different actions (1 action to preload the
data and another to "update" the data)?I think by doing it this way, it
may be easier for me to incorporate the "sensitive form resubmit"
prevention by using tokens.

Any suggestions are much appreciated.

thanks,
Theron

It's simply because EJB 2.0 has local interfaces (1.1 doesnt) , not that
"claim to location independence is eroding".

I wish.  Unfortunately I now believe it's somehow my ISP, as I'm receiving

Re: tag

[Eddie Bush]

While I haven't used this yet, I do recall seeing something about it in the
User's Guide on the main Struts page.  Try looking at
http://jakarta.apache.org/struts/userGuide/building_view.html and see if
that helps.  You may also wish to examine the javadocs.  The information in
one of those two areas should help.
