RE: Suggestion needed on good Struts book

[Chappell, Simon P]

Of course, back in the old days, we just used to read the source code for the example 
application. By the time you figured out it's convoluted approach to everything, you 
were an elite Struts developer! :-)

In terms of books, I like Sue Spielman's book:

http://www.amazon.com/exec/obidos/ISBN%3D1558608621/hitchhikeguidetoA/

and Struts Kick Start

http://www.amazon.com/exec/obidos/ISBN%3D0672324725/hitchhikeguidetoA/

I was involved in the pre-press technical review of Sue's book and found it to be a 
great guide: enough information but no spoonfeeding. At $15, try it, it's not a large 
investment.

| No, you are still going to have a problem with the shared instance
variable when
| two requests occur at the same time.  A general principle you should
follow is
| to *never* use instance variables in an Action (or a servlet, for that
matter)
| to store anything that relates only to the current request.  It's fine to
use
| instance variables to share things that are common to all requests,
though.
|
| An easy way to do this in your scenario would be something like this:
|
|  public class MyAction  extends Action {
|  // protected ArrayList list = new ArrayList(); (COMMENTED OUT)
|  ...
|  public ActionForward execute(...) ... {
|  List list = myMethod(); // NEWER
|  // myMethod(...); (COMMENTED OUT)
|  obj.setList(list)
|  session.setAttribute("buinessObj", obj);
|  ...
|  return mapping.findForward(forward);
|  }
|  // protected void myMethod(...) { (COMMENTED OUT)
|  protected List myMethod(...) {  // NEWER
|  ArrayList list = new ArrayList();// new
|  ...
|  while (rs.next()) {
|  ...
|  list.add(el);
|  ...
|  }
|  // this.list =list;// new (COMMENTED OUT)
|  return list;
|  }
|  }
|

Re: ConcurrentModificationException

[Sergei P. Volin]

Thank you very much, Greeta!
I'm just doing that :)) I'm moving out all instance stuff out of the class
declaration into local methods and transfer them into methods through
arguments.
Thanks to all you guys for your kind advices, I'm on the road now. My old
painfull problem is resolved! I started programming in Struts about 2 years
ago but didn't pay my attention on design guidelines when coding Action
classes. Too shame to me :((

Re: ConcurrentModificationException

[Sergei P. Volin]

Greetings,

That is the question! Today morning I've found the reason of my troubles. It
was my negligence in how I assigned a value to the iterated list that I
placed in the object which I then stored in a session for JSP's iterator. I
declared the list in my action as a global variable, assigned a value to it
in the protected void method which is called by the action execute method
like this:

public class MyAction  extends Action {
protected ArrayList list = new ArrayList();
...
public ActionForward execute(...) ... {
list = new ArrayList();
myMethod(...);
obj.setList(list)
session.setAttribute("buinessObj", obj);
...
return mapping.findForward(forward);
}
protected void myMethod(...) {
...
while (rs.next()) {
...
list.add(el);
...
}
}
}

Now this piece of code looks like:

public class MyAction  extends Action {
protected ArrayList list = new ArrayList();
...
public ActionForward execute(...) ... {
list = new ArrayList();
myMethod(...);
obj.setList(list)
session.setAttribute("buinessObj", obj);
...
return mapping.findForward(forward);
}
protected void myMethod(...) {
ArrayList list = new ArrayList();// new
...
while (rs.next()) {
...
list.add(el);
...
}
this.list =list;// new
}
}

It looks that with this code I rid off all my troubles now - no
ConcurrentModificationException, no doubling of list size. I made a dozen of
tests - no exceptions and the results were correct.

Mr. Craig R. McClanahan! Am I right now with my code? Please, reply.
Thanks a lot,

Sergei Volin.

Re: ConcurrentModificationException

[Sergei P. Volin]

No add, no remove. More interesting fresh result. As I said it happens
sometimes, not always. Sometimes when I send two concurrent requests (from 2
*diferent* browser sessions!) there is no errors at all but the result jsp
data sheet is summarised! E.g. I get doubled amount of elements in the list
on both pages - 304 instead of 152 in normal situation. It seems obviously
that somewhere session objects of two different users are overlapped. How do
you like it?

how it could be. This is really painful to me since I can't even think what
could it be and the issue persists from time to time. And again - the
application works smoothly when there is no collision of requests.

ConcurrentModificationException

[Sergei P. Volin]

Greetings!

Why did I get this message when sending two concurent requests to the same page?
I'm using:
1) RH8.0, Linux 2.4.18 #2 SMP
2) java version "1.4.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0)
Classic VM (build 1.4.0, J2RE 1.4.0 IBM build cxia32140-20020917a (JIT enabled: jitc))
3) Tomcat 5.0.19
4) Struts 1.1

The same exception I've got on 4.1.24. I really have problems (with other symptoms) 
with concurrent requests. Not often (because server is not highly exploited) but 
persisted. And more often on Linux platform than on Windows. Why so? Could it be a jvm 
issue? Or may be Tomcat? Or Struts? Or mine? Without concurrent requests application 
works smoothly.

Regards,

Sergei Volin.

Good point about the testing. I didn't mention it because I was responding to specific 
issues in the original email, but testing is everything. Your end-user/customer will 
not care if you used all the trendy GoF patterns, if the software doesn't work. The 
software must work. Testing is the best way that we have at this time of ensuring 
that. Thus we have:

Learn it, live it , love it. There will be a test (pun intended! :-)

frustrations isn't going to help much?

Thanks for the suggestion about the small company though. Looking back, the most fun I 
had at work was working for a small company.

While the original flame war was less helpful, the question that has emerged
from it's ashes is a good one. I don't claim to have all the answers, but I
can offer some personal observations. Feel free to disagree.

1. You can do nothing about those who choose not to learn. I've tried
changing them and it doesn't work. I consider this a basic fact.

2. You have a great deal of control over your ability to learn. If you
aren't big time into learning, then I recommend catching some enthusiasm for
it.

3. There will be always be good and bad tech leads. I am a tech lead; I try
to be a good one. I can put a String to standard out or standard error! ;-)

4. I had the same frustrations that you have. I made the decision that the
best way to restore the balance of good in the universe, was to try to

newbie/humble grunt. I teach a class on learning Java one lunchtime a week
and try to bestow a little wisdom and encouragement whenever I can. I am a
Java mentor here and I lead a study group of us that are seeking our Java
Certification.

5. No one reads documentation. This is a fact. Learn what is "drop dead
fired and escorted from the building" important and then try to
auto-generate it. :-)

6. Leadership is a rare commodity. There's a lot of management out there,
but precious little leadership. Again, deal with it. Become a leader and
just do what needs to be done. This is what I have tended to do. The ol'

RE: [OT] RE: Memory usage

[P K]

Sorry to continue on this topic. I've learnt a great deal of non struts stuff on this 
list and this only adds to it.
I've been bothered (mostly in my mind) with questions about peoples capabilities and 
desires when it comes to work. Viru, this original poster of the question on Memory 
Usage clearly has a desire to learn, but what about people who don't? How do you deal 
with them?
I currently work with a Tech Lead who wouldn't be able to output a String to standard 
out if asked to write a program. I don't care about her taking credit for the work 
that we do. She doesn't provide any leadership whatsoever to the project except 
produce paper that no one bothers to read. Have you guys come across situations like 
this? What have you done about it? Don't get me wrong - I am not prone to complaining 
nor do I think I am a member of the elite 'Black Team'.

Even questions that don't belong here deserve to be treated with respect. That
is the single most obvious characteristic of STRUTS-USER that is distinctive
(even though it has lots of other good qualities).
Unfortunately, you decided to unload on a poster in a manner that is decidedly
out of the norm for STRUTS-USER. Your response is the kind of behavior that
creates problems for the perception of open source projects as being "friendly"
to users or not. If you think the topic is totally out of scope for
STRUTS-USER, then you should either (a) answer the question anyway but point
people to where they should really be asking; (b) *gently* encourage the user
to explore the other resources that are available (the archives are full of
examples of folks who have done this), or (c) shut your yap and press DELETE
instead of SUBMIT on your replies :-).
The culture of the STRUTS-USER list has always been *deliberately* different
from the "you idiot, how could you be so stupid as to ask that question in that
way" sort of attitude that far too many open source projects have. 
Fortunately, despite the fact that this is the most-subscribed-to user list at
Jakarta (ten short of 3000 at the moment), the occurrences of rude behavior are
so rare that they immediately attract notice for being out of character for
what we're trying to achieve :-). I'd say that we've been doing a pretty good
job maintaining a friendly, welcoming, and helpful community. I'd also like to
keep it that way.

RE: Debugging JSP

[Edgar P Dollin]

In my experience, if your jsp is so complicated you need a debugger, you
should write java classes and/or tags and debug them using junit/httpunit
and logging.

RE: [FRIDAY] RE: What does "do" stand for in .do files

[Chappell, Simon P]

Quite so.

And never underestimate the space savings that come from using a lower-case oh instead 
of a zero and a lower-case i instead of a one. Being smaller, the "o" and the "i" take 
up less space than the "0" and "1" ... in large programs this can result in quite 
significant space savings.

This wisdom brought to you by the Struts Mailing List Friday Afternoon Club. :-)

Re: session control

I think having objects in the session is no good solution. It might have 
a little bit of global variables, but thats only my 0.02$. I try to 
group objects into own contexts - I call it action-contexts, and allow 
actions only write information in these context. So you have better 
control which objects may removed.
Some architectures put _everything_ behind one big application
facade, so that other than various forms you are always dealing with the
same applicaiton object on all pages.
Others might think that a few objects is the right balance between
1 large application facade and lots of curiously named object running
around in the session.

RE: [OT] RE: log4j integration

[Chappell, Simon P]

We do specify the log filenames in each properties file, so we don't have any 
possibility of overlap there.

We did have a problem with JRun 4 before we switched to WAS, because it came with an 
old version of log4j in it's internal library. This caused us no end of problems and 
we did have to put log4j in the server classpath to overcome the issue. This has not 
been a problem under WAS 4.x

RE: [OT] RE: log4j integration

[Chappell, Simon P]

Jacob,

We use log4j 1.2.8 and we include the jar file right in out WEB-INF/lib directory of 
our application. The log4j.properties file then lives inside the WEB-INF/classes 
directory. This works well for us on IBM's WAS 4.x.

I've never seen anyone recommend having log4j at the container level, so go with it at 
the application level and forget about conventional wisdom! :-)

Hope this helps.

Simon

Re: Torque and Struts problem

[P. Daniell]

The problem is neither with Struts nor Torque but rather with the reflection
API, which exhibits strange behavior when asked to deal with classes named
"Component." Strangely enough, I found a thread on the struts-user thread

http://www.mail-archive.com/[EMAIL PROTECTED]/msg60817.html

dealing with the same problem. Everything behaves properly when the class is
renamed Komponent.

Favorite tag reference?

[P. Hill]

Hi,

Just thought I'd ask if anyone has any favorite on-line or paper references for
the various tag libraries.  Reading the new JSP 2.0 spec is certainly the brute 
force and often instructive approach and each of the taglibs in struts contains
a reference like:
http://jakarta.apache.org/struts/userGuide/dev_bean.html
Just wondering if others have found any useful on-line summaries/references
just to look up summaries, explanations, and maybe short examples for the 
various libraries.

What's your favorite? Are the Apache doc's as good as any?  Better than
some? Worse?
TIA,

RE: Unit Test in struts

[Chappell, Simon P]

On our intranet application, we make a round trip to the server everytime the user 
enters a piece of data. This sounds like it would be dreadfully slow, but in practise 
it isn't. Internally, we have bandwidth to spare and we keep our pages fairly 
streamlined (need to switch to CSS, so that we can shrink them even more, but they're 
not bad even now). So our users get their dynamic feedback and we threw out JavaScript 
... a win-win situation if I ever heardof one. :-)

Could you share with us how you worked around some of my issues, i.e.

The user is entering items.  User needs dynamic feedback as to to how much
is entered 
so correctness of data entry can be determined.

RE: Unit Test in struts

[Edgar P Dollin]

Maybe I am not smart enough for my applications (order entry, inventory,
etc.) 
I just don't see how to give any real functionality in the
application space without JavaScript.  

Some issues where I don't see a work around for which are intrisic
to all the applications I am working on.

1) The user is entering items.  User needs dynamic
feedback as to to how much is entered so correctness
of data entry can be determined.

2) User can't remember a code from a 'large' list and
needs to look it up and return to where he was with
the correct value filled in.  Perhaps it can be done
with some fancy footwork with actions but...

3) Menus, yes there are plenty of static menus but
all the real ones are javascript, i.e. coolmenus
cannot be tested with the existing test tools.  Menu's are
not required to be tested but it would be nice.

RE: Unit Test in struts

[Edgar P Dollin]

I have spent a fair amount of time with WebTest and HttpUnit.  The major
issues with both of these are JavaScript related.  For example if you use
JavaScript to populate select lists or html objects they are not available
in WebTest or HttpUnit (HttpUnit is a little better since you have finer
grained control).  

How does jWebUnit compare?

Thanks.

RE: Unit Test in struts

[Chappell, Simon P]

Well, we use Junit for testing our business logic (you do have your business logic 
split out into seperate objects right?), HttpUnit for functional testing and JUnitPerf 
for performance/load testing. We use all of these right now and are very happy with 
them. (ok, the DOM stuff in HttpUnit sucks, but we wrote our own tag content utilities 
and forgot about converting HTML to a DOM model.)

I'm actually just in the process of trying out StrutsTestCase 
(http://strutstestcase.sourceforge.net) for testing our actions. I got the examples to 
work, but I haven't gotten any further than that yet. Is this the tool that you were 
asking about?

RE: Struts-Menu (Support URL Re-writing)

[Edgar P Dollin]

Unless I am mistaken the relative url in struts-menu is just the text passed
in from menu-config.xml.  

In the CoolMenuDisplayer it calls, buildMenuString --> getArgs --> getUrl
which unless there is prior transformation the string from the config.

Let me know if I am seeing it wrong or if this is different from displayer
to displayer.

Thanks.

Subject: RE: Struts-Menu (Support URL Re-writing)


Struts Menu makes use of Struts classes to support "forward" and
"action" attributes.  If you use those, you'll likely get the re-writing
you're looking for.  I did this on a previous project and did find that
the "forward" attribute worked, but not the "action" attribute.  I
believe this is a bug in Struts since it should do rewriting when
looking up an Action's path.

The one issue with re-writing is that if you're using a menu that
matches URLs (i.e. tabbed-menu) - they probably won't get matched up.
At a previous project, we were using URLs to highlight the current page
we were on and we found that we had to use the "action" attribute or the
"page" attribute so that the jsessionid wasn't appended.  Of course, we
could've stripped this off in our Velocity template, but we wen't with
the quick, less-logic, way.

To see this project, go to http://telluride.resortquest.com and drill
down a bit.  The menu with highlight is on the right.  BTW, this site
uses the Velocity displayer for both the top menu and the side menu.

If you're not familiar with struts-menu, checkout the demo at
http://raibledesigns.com/struts-menu.

RE: Session Problem

[Edgar P Dollin]

If IE opens a new window (either through javascript or from the
file/new/window menu) and IE is in a session, the session is shared between
the two browser sessions.

If you open two copies of IE from the operating system, they will not share
the session.

The only way to solve this that I know of, is to keep a session token, if
you find it out of sequence, forward to a page which closes the window (if
javascript is enabled).  If you use tokens on your update sequences you
should be able to live with the two browsers in the same session.

I had a similar problem.
I have two browsers opened with diferent sessions (and logged on with
different users to my app) in the same machine.
In one browser, I click a button that opens a new window (window.open in
javascript) and in this new window a submit is performed to an action of
struts. This action has an execute that checks isTokenValid and gives
false, not because I haven't saved token first, but because session are
different. 

 */
protected boolean isTokenValid(HttpServletRequest request) {

// Retrieve the saved transaction token from our session
HttpSession session = request.getSession(false);

//--> here, session id is different of the main window
session, but equals to the other window session.

if (session == null)
.
.
.

//as session id is wrong, token is invalid.
}

If I have one only main browser opened this problem doesn't happen. I
think that it can be a window.open IE problem, but I still couldn't find
out a solution. 

If anyone has one...
Thanks..

How do I make sure the session on both the browsers will be different
other than URL Rewriting. 

This I do not know. :-(
You can take a look through all the browser options and see if there is
anything to make it associate cookies only with a specific window, but I
would be quite surprised if there is such an option. I suspect in the
absense of url rewriting you will need to use either different machines
for each browser, or a different browser (ie open second window in
mozilla or something). Hopefully Im wrong on that and someone else on
this list has a better idea!

I tried to use URL rewriting explicetly for session tracking,
unfortunately I wont be able to use this because Its not been guaranteed
in the code is been written using  always for the links. As
both the browsers sessions are using only the same cookies, so I think
the problem is because of that. How do I make sure the session on both

On the same machine? Rather sounds like its the same session. Im not
sure about IE6, but as I recall, IE5 will share its cookies between the
various windows if cookies are enabled. If cookies are disabled then url
writing takes over (asuming youve made sure your links are re-written by
using the appropriate tags) which means they shouldlnt share sessions if
opened seperately. You could test this theory by disabling cookies in
your browser and see if it makes a difference.

Put it a log statement somewhere to log the sessionId and compare the
results for both the windows to see if it is indeed a different session,
or if the second window causes the first window to end up in the
second's session.

FYI, using HTTP 'error' 202 SC_ACCEPTED (and maybe others) works around the

will find out later if this issue is truly resolved.

I have a an interesting issue which at first blush doesn't seem solvable but
could be a bug in struts 1.1 or my use of struts. 

I have a partially implemented struts application which is using filters for
security (not the sourceforge security filter).  I used to issue a 401
error, have the container trap the error and forward to the logon page.
That worked fairly well with tomcat 4.1.18.  I had a testsuite in
Struts-Test, HttpUnit and WebTest which was working reasonably well.

I updated to tomcat 4.1.29 which passes the http 401 error to the page, with
the actual login page.  This causes failures in HttpUnit and WebTest which
assume a 401 error is a Basic Authentication Error.  I thought about
throwing / catching other errors but have not completed tests.

The sourceforge security filter just does a RequestDispatcher forward to the
login page.  This works fine on straight jsp pages.  However on struts pages
there is some additional processing and something (I have not yet figured
out) from struts gets put in the response so that there is an
IllegalStateException thrown when the filter performs the forward.
Additionally, response.redirect has the same issue.

The only struts log messages have to do with PropertyMessageResources, which
are not there for both straight JSP and struts resources.  Does anyone know
what in struts could be writing to the response or where to start looking?

Thanks in advance.

RE: Data Sources problem

[Edgar P Dollin]

I don't mean to discourage you however you are developing an application
using struts.  The current struts datasource is deprecated and it is
recomended that you use either a jndi datasource or a product like poolman
on sourceforge or a DAO product which maintains the datasource itself.

I suspect your problem is due to not including struts-legacy.jar since the
datasource is only marginally supported and was not included in the base
jar.

[Sergei P. Volin]

  Hello Ted-

  I'm a newb w/ Hibernate and not Struts. With some difficulties but
i've managed to install struts-hibernate example on Tomcat-4.1.24 and
Firebird-1.0. And have a lot of questions.
  What should this example show? I mean how to play with this example? I
did not find any help, only readme about how to install this example. Well,
I've installed it. What next? I see a text entry with Submit button and 3
links at http://localhost/eg1/Welcome.do. What should I enter? And what
shall I expect after pressing submit? Really lost.
  Moreover, when i press submit butoom (whatever i enter) the result is
always error. Why? I see message - Could not execute query. And find it:

  public static String HQL_FIND_USER = "FROM user IN class eg.User WHERE
user.userName = ?";

  Is it really a problem in this query? Its incompleteness? Tomcat
complaints on dot. Or is this a firebird sql specific problem?

  Really appreciate your comments,
  Sergei.

RE: [OT] Canoe Webtest / HttpUnit

[Edgar P Dollin]

Thanks for the article.  Something about the update from 4.1.18 to 4.1.29
caused my cookie test javascript to give inconsistent feedback in the
HttpUnit javascript.  I tried another algorithm and worked past the error.

BTW for you test junkies, if you used web.xml  to
trap http errors and return a different page, tomcat 4.1.18 doesn't pass on
the http error with the page redirect while 4.1.29 does.  Tests of pages
which take advantage of those automatic redirects will start failing when
you do an upgrade.

Thanks again.

Edgar

[OT] Canoe Webtest / HttpUnit

[Edgar P Dollin]

I have been struggling with these two testing tools for a while now
attempting to retrofit http tests over an existing working application.

JavaScript has been a bear, stuff that works on Mozilla and IE breaks in
HttpUnit (not that the review didn't turn up myriads of errors).  Repairing
the scripts has really strengthened the code.

I know that others on this list use Canoe Webtest.  It is much nicer writing
Webtest scripts than HttpUnit java code.  

However, I am ready to give up on WebTest, but before I do would like to
hear if others have had similar problems.  The issue I can't seem get around
is that my site requires cookies.  I have a hidden field and some javascript
to test if cookies are enabled and value the hidden field.  Webtest won't
value the field and won't let me set the value of the field.  Additionally,
this issue cropped up when I upgraded from Tomcat 4.1.18 to 4.1.29.

Any insight is welcome.

Thanks.

In your load action, always fill out the entire form.  As long as you
session based form beans and don't use the reset (for checkboxes) the data
will pass without input fields in the jsp.

I am a believer in standard actions and have your business classes implement
interfaces for the actions to use.  So in the save/update/delete sequence
you have a single action which calls standard functions in your business
classes.

RE: Is there a way to prevent urls from being entered from the browser?

[Chappell, Simon P]

It wouldn't be useful for most people, but for an intranet application where a regular 
PC would be overkill, it made sense to use thin clients, and even more sense to use 
touchscreens and toss the keyboard and mouse (we have space constraints in the packing 
stations as it is, there was no way that the engineers would give us room for 
luxuries! :-)

It is a complement that Microsoft is worried about the feature set of

Save session state to db... I hope no one here does that (but I do think 
that if .Net suggests for them to do it, GREAT)

Version is a strength of .Net? Have you ever had .DLL hell?

OK, I do not think the author knows that J2EE comes with built in JAAS 
and... it's declerative role based security. Struts and other tags uses 
Servlets (since 2.2, go read JavaDoc) Role based API.

Again, I do not think the Author is familiar with localization in 
Java... for example JSTL's localization.

Again... on testing, I happen to use OpenSta that runs circles. I think 
he is implying that I can't test in J2EE. The benefit of MVC layers is 
that you can test each layer.

PageController is an MVC? Looks a lot like MV... with a small c.

This is commic: "How to migrate Struts to ASP". ??

That is what I want to do, get propiratory with a Vendor, who want's choice?
You know, clients no longer say should I use .Net or Struts, topic 
just does not come up for large projects.

Oh, does it run on the largest comercial platform, Linux?

I do my development on Linux, w/Eclipse and Tomcat and pgSQL. but, every 
3 months, I reformat my windows machinee and re-install XP.
I do not do this with Linux(Fedora)... and I guess my new OSX is BSD, 
but I have had it less than 3 months.

This question comes up periodically, so I started a list of Struts-powered sites.

http://simonpeter.com/techie/java/struts/sites.html

I hope this helps.

I know that I wouldn't like to think about not using it on the Intranet application 
that I head up the development team for. It has greatly aided our productivity and has 
now come through it's second peak season with flying colours. We started with Struts

RE: Connection Pooling

[Edgar P Dollin]

Drop connection pooling in struts and either go to Container pooling or use
a product like Poolman (on sourceforge).  Struts DataSource is no longer
supported.

I'm trying to think how to explain this delicately ... consider the process:

1. drink beer
2. use bathroom
repeat

Now carefully consider step two in light of the word "recycling". See? Now ... be 
careful about drinking clear yellow liquids. ;-)

RE: Tabbed menus using Tiles

Try struts-menu at sourceforge.  It integrates very well and gives you nice
choices for menus without writing a lot of javascript.

RE: HELP: about to get datasource of struts and pass to logic bea ns...

[Edgar P Dollin]

Don't spend the time to get DataSource working.  It is deprecated and will
be removed from struts in 1.2.  I use Poolman at sourceforge (I highly
reccomend it for non-j2ee projects).  Most others use the DataSource
supplied with the container.

There are lots of classes involved.  I will give you
an example:

1. my LogonAction calls EditorService.java (business
delegate)
2. EditorService.java calls MySQLEditorDAO.java (data
access object implements EditorDAO.java, which is a
data access interface)
3. the MySQLEditorDAO.java returns EditorBean.java (a
Java bean with three properties)

Here is my LogonAction.java:

package org.apache.artimus.logon;

import java.io.IOException;
import javax.servlet.ServletException;

If you use container authentication or filters, this isn't an issue.  The

If he's using Servlet 2.3, then he can also use the 
ServletContextListener in conjunction, where is where the logic for 
whether the session has been restarted could likely belong.

truncated data in the form

[Sergei P. Volin]

Hi there,

Can anybody shed light on why data sent by POST is truncated sometimes. The
form is actually sufficiently big, 200kb (it is a survey form). The form has
text, textarea fields, checks and radios. The fields that are truncated are
text and textarea types. The problem occurres not often but persists. Could
it be some "bad" symbols that users enter? Then what are they?
It is more a html specific question than struts. But once I use struts
(struts-1.1) I place the question here.

Best regards,
S.Volin.

RE: Server manged vs. struts managed db pools

[Edgar P Dollin]

I will speak about tomcat since that is the one I have used most recently.  

The web.xml file which is in the war file has a reference to the JNDI
objects created by the container.  Say you have the same application
deployed multiple times (one for each customer).  In my application(s), each
customer has a separate physical database which means that you have to mess
with server.xml in the web container configuration to add the additional
database for each customer added (not really an issue if you are adding
context elements for virtual servers).  Additionally, you don't need a
configuration parameter in your application for the JNDI database handle as
it can be hardcoded and only change struts-config.xml to reference the
correct database.

RE: Does Taglibs cause any performance Issues ???

[Edgar P Dollin]

Tags stay in memory (in pools) based on the tags used and the parameter
values of the tags.  If memory is an issue then you can disable tag pooling.
If cpu performance is an issue (pooling the tags saves object instantiation
and release) then leave tag pooling in place.

RE: Types supported by DynaActionForm (or DynaValidatorForm)

[Edgar P Dollin]

There is some contradiction when it comes to types in ActionForms.  The
general idea of struts is to put a bunch of Strings (or booleans) between
the application and view layer so that after unsuccessful validation the
framework can return the typed values unchanged.  In certain cases,
individual developers put in support for types other than Strings for
certain features.

The bottom line is, until there is more concensus on the use of data types,
use non String ActionForm properties at your own risk.

RE: Server manged vs. struts managed db pools

[Edgar P Dollin]

There is another issue regarding connection pooling in struts vs connection
pooling in the container.  In struts the war file contains all the
information the app needs to run.  With container pooling (at least with
tomcat and resin) you have to coordinate the container configuration with
struts configuration.  With a single container running multiple apps this is
a bit of an issue.

RE: [OT] Stress Test

[Chappell, Simon P]

I must admit that I have not tried JProbe or Clover, so I can't help there.

I liked JUnitPerf for the task that I had. I originally wanted to use JMeter, but was 
unable to figure out quickly enough how to have unique test data for each simulated 
user, which was crucial for the test that I wanted to run. Also, the tool had to work 
from within Ant, which both JUnitPerf and JMeter will do.

RE: [OT] Stress Test

[Chappell, Simon P]

I stress-tested our app with a combination of HttpUnit and JUnitPerf. My test was 
designed to see what the maximum throughput was, rather than testing longevity, but 
the basic principles should be the same. I had multiple simulated users, logging in. 
each in independent sessions, and then running unique data through the application.

RE: Token documentation

[Edgar P Dollin]

I haven't seen any but there isn't really much to document.  You put an
integer into the form with a value that is updated by the action.  This
value must change from request to request, typically it is incremented.  You
must carry a hidden field in the jsp to carry the token to the following
request (if you don't have the hidden field and are using session beans the
value will always be correct, with request beans it will always be
incorrect).  The load action also puts the token value into the session so
the next action can check the value.  When the target action is invoked, it
picks up the token and checks the value against the actionform.  If the
value is not the same, i.e. the user hit the back button and resubmitted,
you have an error situation.  You can forward to an error page or take
whatever action you deem necessary at that point.

RE: Lazy questions on this list

[Chappell, Simon P]

Perhaps, instead of just pointing people at the smart questions FAQ (however much it 
seems like the right thing to do), we could point them at the appropriate entry in the 
various Struts FAQ documents. This would be a much more helpful thing to do and over 
time people would both get help and maybe even get the hint that there are places to 
look before asking the list. And if appropriate FAQ entries do not exist for such 
questions, then shame on us long-time Struts users (me included)!

Be nice to the newbies, because eventually, if they stick around, they become the 
grizzled old fogies like me and Mark and a few others around here.

So everyone raise their right hand and repeat after me: "I will not flame the newbies, 
and I will point them at appropriate sections of the FAQ" See, that didn't hurt. :-)

RE: MessageResources...

[Edgar P Dollin]

A brute force approach is to loop through the context objects looking for
ActionMessages or ActionError objects which contain the key you are looking
for.  Of course, once you have it, just put the key somewhere for future
reference.

RE: URGENT:static methods in JSPs

All the tags us introspection to access the objects.  Introspection works
only on non-static public fields and methods.  You must find a way, possible
with a façade, to make your static method non-static.

You are right.  This is not the right forum.  

The reason you are asking on this forum (you will get a good answer quickly)
is the reason you are using struts and the reason struts has a future.  All
the other frameworks except for JSF and Microsoft are of technical interest
only.

Mappings

[Edgar P Dollin]

Has anyone encoded map keys as path parameters in the struts config?  I am
doing this but was wondering if there were any 'gotchas' I haven't forseen.

What I am doing (in MockStrutsTestCase) is using the 'success' forward from
an action be conditional or hard-coded.  If it was conditional (developer
would use the 'key' as the path in struts-config) the forward path is looked
up elsewhere, else it is used as is.

Thanks in advance.

struts source (newbie)

[J P]

Hello,
Pardon me, but Struts by nature is configurable / extendable and therefore 
editable? One would quite frequently like to get into the source of the .javas? I have 
downloaded and installed 1.1 but can see nothing but classes, JARs and WARs. I for 
expample want to configure the ActionServlet, but cannot becasue I cannot find the 
.java! I have unpacked the JARs and WARs but the source is thus far elusive. In the 
struts-blank app for example, all classes and config files are present, but what of 
the source? Is it not included in the distribution or is it separate?
 
Regards
 
Eager 2 Start.

RE: Session Timeout on post

[Edgar P Dollin]

Strictly a container issue.

If you keep the login information in hidden fields, you will be able to
reinstate the user session although the session information will be gone.
You should be able to post the submited record however.  You can use a
filter for this.

Or, if you're using Ant, try the optional xmlvalidate task (this is almost
exactly one of the examples given):

StrutsTestCase and Multiple Struts Configuration files

[Edgar P Dollin]

Has anyone used StrutsTestCase with multiple comma-delimited struts
configuration files and multiple message files.  If so are there any issues
which might make it less straight forward than straight struts?

Thanks

Edgar
