LOL!

Yes. 'Tis true. I would suggest a different approach, but it is irrelevant.

Re: abstract class

[Brian Hickey]

Mohan,

Two different behaviors is what you wish then you need to derive from a
concrete base class. Abstract classes are more likely to provide conformance
to an architecture or signature template.

In Struts, folks usually inherit from the Action class to create certain
behaviors. If you need to super() to a base class, you are correct, it
cannot be an abstract class. I would suggest that it shouldn't be in most
any case, but I don't know your architecture.

It is also early and I am not sure of your terminology. A base class is a
super class (standard inheritance diagrams display that way) and subsequent
derivations are known as subclasses. When you want to use the code in a
super class from your sub class, you user super() to call it. So your sub
class (a derivation of your base class) needs to call into its super class,
it is done with a super() call. The super() call is (and must be) the first
statement in the subclass's overriding method.

All of this seems too easy, so I am sure I have completely missed the point.

Brian

Re: Struts Log

[Brian Hickey]

Wilson,

If it is a standard install and seeing as it is 1.0.2, it is most likely
that there is no Struts error log file.

Tomcat has log files for Jasper(the JSP compiler), Servlet (servlet inits),
and any mods like mod_jk that you may have installed with Tomcat. These are
populated on startup and don't normally contain errors and will not contain
runtime errors, so no help there.

There is only sterr and stdout. So, in Windows NT, you may use a command
prompt in a window to start Tomcat and it may start in that window or open
its own. In this case, the window itself is stderr and stdout. So you would
see runtime errors that wrote to stderr/stdout in that window. Not much
help, but if the error is generated and writes somewhere, that is where it
will show.

If you don't see anything there, you may need to do some
System.out.println()'s in your code to trace the execution.

The interesting aspect is that you are NOT getting a stack trace. Let us
know if you can see the error anywhere other than the browser.

Re: Struts Log

[Brian Hickey]

Wilson,

Logging is dependent on many things. Which version of Struts? What JSP
container? (i.e. Tomcat 4.1.X), are you using Log4J or jakarta-commons
logging?

It would also help if you showed the actual error message.

Re: Struts: a Graphic Artist blessing or curse?

[Brian Hickey]

I don't think management of a development staff was a goal of J2EE :o)

It is separation of process and/or skill sets that Struts/MVC provides for.
Whether this happens or not is up to people, not software... yes?

The method you refer to in your last paragraph is quite common and works
quite well. If someone can do all of the tasks in a large Struts project,
they are highly skilled, very experienced and are probably compensated quite
well.

Struts taglibs, like most all taglibs, are converted in the servlet and HTML
equivalents are "emitted" as the browser only understands HTML. Perhaps this
is the piece that designers/web developers struggle with.

FWIW, graphic design and Java development generally use different parts of
the human brain. It isn't to say they are mutually exclusive, just that it
is difficult to switch back and forth between these skills.

Tiles newbie

[Brian Hickey]

A coworker asked the following question "Can I implement Tiles as a stand
alone?"

I was busy so I said "Not likely and we are only in production with 1.0.2"

A quick search (if there is such a thing) of the archives reveals a lot of
Tiles info, but nothing specific to his question.

Does anyone know if I was too quick with my answer?

Re: Struts file upload validation problem

[Brian Hickey]

Martin is correct :o)

Also be aware that very very large files can exceed the setting of Java temp
space (memory) allocation is some containers and crash them.

One approach that works is to write a simple file upload script in Perl.
This allows you to check content-type, size, etc. and reject the upload
before trouble happens. It is also platform independent to a "reasonable"
degree.

Just another $.02 worth...

Re: How to Redirect ???

[Brian Hickey]

Wolfgang,

Redirect outside of an app can be done a number of ways.

One suggestion:

Map your redirect to a class that creates the forwardURL.
Put the forwardURL into request scope.
Create a JSP that does nothing but the redirect. Map to it in struts-config.
use the jsp:usebean and  tag to perform the external
redirect.

The advantage of this method is logging which can be done in the class and
you have no context other than what you specify in the 
tag.

Re: "deferring" an action

Alayne,

Would a time requirement mess things up? If not, your actions could simply
place the forms into session scope.

Most of our clients don't spend all day at their machines, so 30 minutes or
so is too much of a constraint...

Re: Re: user manually changing local

Marcus,

What datatype does getLocal() return?

I would likely write:

SetLocalForm myForm = (SetLocalForm)form

first and then:

String localString = myForm.getLocal();

or:

String localString = myForm.getLocal().toString();

It may not execute and differently, but it keeps the cast separate and
clear.

Re: Problem with using Vector?

[Brian Hickey]

Jana,

I think I see part of the problem. Here is some further info:



-- When you use type="com.ViewListingBean"... do you have a class named
ViewListingBean that has a 'package com' directive at the top? If so - good.
If not - that needs to be corrected.

-- The "id" in the usebean tag refers to the exact name of the bean your
action class placed into request/session scope.

-- The logic:iterate should look like..


-- Then you can use tags nested in the iterate as:



You are correct - JSP/Struts will not allow redefinition of beans with the
same name in the same page/template/tile.

Re: Problem with using Vector?

[Brian Hickey]

Jana,

It would help to see the actual error.

More below...

This says you have a bean named "ViewListingForm" that has some scope
(request/session) in your JSP. Also that you will refer to that items in the
property collection in "listingsSummary" by the scripting variable
"ViewListingBean". The property accesses the collection (List/Vector) you
want by calling the form getter for "listingsSummary".

To be thorough, you will need to include the "type" attribute to identify
the object type that will be found in the collection "listingsSummary". It
looks like type="java.util.Vector".

The getter will be called by the iterate tag for "listingsSummary" and you
have the case correct.

Always check the Javadoc (start at: http://jakarta.apache.org/struts/ ). The
"id" attribute names the scripting variable you will use within the iterate
tag. In other words, each object contained in the Vector "listingsSummary"
will be referred to as "ViewListingBean".

So you can now use ViewListingBean to access the individual properties of
the objects in your listingsSummary. For example

Re: [OT] Serialization issue - stream has problems flushing?

[Brian Hickey]

Eddie,

HEH :) The only things I have been able to "geek up" were serialized objects
in J2EE. One time was a classpath problem and the other was some goofy
versioning thing that insisted on calling every method except the one I
wanted ...

Darn computers. Don't they know what we want to do?

Re: [OT] Serialization issue - stream has problems flushing?

[Brian Hickey]

Eddie

If he is writing his own wrappers then the class should take the basic form
of this:

import java.io.*;
public class ser {
 public static void main(String args[]) throws IOException
 {
  FileOutputStream f = null;
  Integer i = new Integer(1);
  f = new FileOutputStream("tmp");
  ObjectOutput s = new ObjectOutputStream(f);
  s.writeObject(i);
  s.flush();
  f.close();
 }
}

Forgetting to use the flush() method will cause what he observes.

Can it be that simple?

Brian

Re: Tomcat/Apache and .do

[Brian Hickey]

Marc,

The simple answer is:
Struts uses the action mapping, not Tomcat/Any other web server.

The action mappings are defined in struts-config.xml.

Tomcat also uses (by default) port 8080. Do you have Apache installed
w/Tomcat/whatever?

Re: Last for words with forwarding can someone please help me out here

[Brian Hickey]

Much information missing here. Which version of Struts? What does the code
look like?

Scoping manipulates what the page sees, not what the form bean contains.
That makes it interesting that you can change form bean contents by managing
scope.

If you have time, please give more info.

Thanks.

Re: Am I the only one using java.util.Date?

[Brian Hickey]

Rick,

You are on the right track. A suggestion would be to break the month, day
and year out on your forms (makes nice-nice with html:select) and provide
the code to populate them in your form instance. The conversion is actually
quite simple:

public GregorianCalendar getStartDate()
{
  return new GregorianCalendar( this.getStartYear(), this.getStartMonth()-1,
this.getStartDay() );
}

This getter (exists in the same form instance) will hand off the startDate
as a java.util.Date to your (dyn)Action.

HTH

Re: xml, jsp, DOM

[Brian Hickey]

Frederic,

I can give you the business case for Struts. Read on if you dare...

Struts allows the separation of layers (the Model/View/Controller) in any
application.

This provides many things including assignment of skills to specific areas.
Database developers get to do database development. Java developers get to
develop Java. HTML developers get to do HTML with (hopefully) a minimum of
Struts/JSP tags. Managers of software teams like this. It is easy and
efficient.

If a company is honest, they should admit that the value of their
application is in the data (Model) and the business logic (Controller).
Although pretty, the presentation layer (View) is what I call a "throwaway".
If they don't use good architecture, they end up chained to the presentation
layer and they spend large amounts of money on any changes to it. Struts
helps avoid this (still need good design and code) by making the
presentation layer "expendable" and "expandable".

A well designed Struts application can support web browsers, cell phones,
PDAs, and anything that may be invented for the forseeable future. All done
with a change or addition of simple presentation layer. Almost painless.

By use of sound techniques, all of your application is derived from the base
Struts classes and you can easily create additional convenience classes that
you can derive from or reuse. This makes each subsequent iteration of the
application easier and easier, not to mention taking less time. This equates
to dollars (or lire) saved.

Now the decision a company has to make is twofold:

1. Is Open Source a solid enough foundation to develop on?
2. Is it worth the time to adopt the OO techniques and Struts knowledge now
to the development team to save money later?

You may guess that every company may have different answers and you would be
correct.

In my humble opinion, Struts is based on best practices and solid OO Design.
That matters to me because I will always choose to be proactive over being
reactive in application development.

HTH

Re: SQL Query Builder [Off Topic]

[Brian Hickey]

Suggestion - simplify

Layout a JSP page using radio buttons (Or's) and CheckBoxes (AND's) that
coincide with the fields/values/whatever. If you can layout the page and
make it simple, logical and functional, then you can write the qualifier
class(es) to build your WHERE clauses. Swing is likely overkill.

Only a suggestion based on the K-I-S-S principle.

The Amiga was the first machine and OS to use "flat" memory addressing. It

As for WebObjects, it is one of the two branches of history that the top

Re: DB hit from ActionForm Validate method

[Brian Hickey]

Sean,

-- 

IMHO, the answer is: logins are DB functions. Your role as a Struts
developer is to simply request the login and read the results of the
request. Understand that when you drag DB functionality into your Struts
app, you risk complexification (how about that word?) of your app and your
code. You may make maintenance a nightmare down the road.

Any DB worth a hoot has the capability of locking out users after X number
of attempts. It's a DBA thing as to how many and then how to reset.

Just a suggestion, but don't go there. You request the Login and wait for
the response. If it's bad news, report it to the user. Struts is all about
separation of Model - View - and Controller.

Re: struts & complicated forms

[Brian Hickey]

Bram,

I am sure if you think in terms of a list or an array, you will see that
what you wish is not only possible, but normal.

Use the html:radio tag and assign the property attribute to the form
property. The length of the array/list will tell you how many groups the
page was populated with and each item will provide you with the choice.

Subject: struts & complicated forms


I'm fairly new to struts, but I've encountered a problem.
I want to present the user with a list of radio button groups, each
consisting of a fixed number of radio buttons (=4).
The number of groups (ie. the length of the list) is dynamicly determined.
Therefore I'm unable to create an (Dyna)ActionForm class to capture the data
on submit.

My question is: how can I capture an undefined number of radio button groups
into one action form?

I am using struts 1.1

Thanks in advance,

Re: text input and style sheets

[Brian Hickey]

Mark,

Check the doc first, but I think you will find the following should work:




this assumes you have a form bean with the get/set property named startDate
and containing a default value of "01/01/2000". If you don't want to access
the bean for a default, simply use the value= attribute to designate the
default.

Using a form bean has a benefit. You code the reset() and validate() methods
yourself. You control what the user sees on error.

Our HTML/design person has created our text input boxes with the following
code



I am trying to figure out a couple things...
1. How do I implement the class attribute within a stuts tag.  I am assuming
this is a CSS thing, since I haven't used it before.  anyone know?

2.  How do I set a default value for the input field?  if I said it
explicitly like so:



then the associated form does not repopulate the form field if there is an
error.  is the only way to do this, to make it an initial value in the form
object?


thanks,

Re: [LISTEN UP] Mailing List Usage

[Brian Hickey]

Craig,

Thank heaven there are humans out there :o)

I do what you describe - here is the snippet:























Then, in the Application class I call:

  public void initDatabase() {
  // try to get a db handle
  DataSource ds = null;
  Connection dbConn = null;

  try {
  ds = super.findDataSource(null);
   dbConn = ds.getConnection();
  } catch (Exception e) {
   return;
  }

In the end, the log shows GenericDataSource properties being overwritten
when the second datasource is processed. The end result is that the
erstwhile "default" connection is always pointing to the second datasource
and fails to load any data from the first datasource.

Perplexing, eh?

Thanks for any thought and effort !!

Brian

Re: [LISTEN UP] Mailing List Usage

[Brian Hickey]

Maybe I should bracket [NTTL] for New To This List. I have no idea of
"Subject" protocol and posted a question about multiple data sources
earlier. Either I posted something entirely lame or I posted something folks
have to think about - alot.

If this were an EJB list I would post an in depth question on determining
isolation levels, but it isn't. So, I will rephrase the original question in
hopes that I can gain some insight.

To wit: "Do/did all versions of Struts support multiple datasources?"

"If so, why can I not get ActionServlet.addDataSource to do anything
other than overwrite the existing GenericDataSource properties?"

As for OT posts, I am neutral. If I can both give and receive assistance
with Struts - it is working fine.

Thanks

Brian

Muliple Data Sources

[Brian Hickey]

Anyone done this successfully?

I have the December 2001 release of Struts (I think this is 1.0) and I am
developing a webapp that has a need for two datasources. I modified the
struts-config and, leaving the default data-source without a key, added the
new data-source (same Oracle database - diff user/pwd).

...

   
   
   
   
   
   
   
   
   

...

The Application class calls:

 public void initDatabase() {
  // try to get a db handle
  DataSource ds = null;
  Connection dbConn = null;

  try {
  ds = super.findDataSource(null);
   dbConn = ds.getConnection();
  } catch (Exception e) {
   return;
  }
.

I gen the .war file and deploy it. Tomcat starts and you see the first
data-source load and:

org.apache.struts.util.GenericDataSource
properties are set to the default (null key). Then you see the second
data-source load and the GenericDataSource properties are set to the second
data-source.

Now - when the inits run, he runs the queries against the second data-source
even though I am using the null value for DATA_SOURCE_KEY. ARGGH!

I stumbled through the Digester code and the format of data-source seems
correct.

Can anyone assist? I am pulling what little hair I have left out :o)

Thanks in advance.

Brian

BTW - I also tried naming the default data-source with a key = "default" -
no go. He loads, but the behavior is the same.
