Hi Rajat,
I don't know if it is a good idea to answer all your questions with a
straight yes without knowing your implementation. It could be possible to port your
application to struts but you have to be careful.

Re: [OT] JSP or Velocity

[Markus]

Hi,
I've used JSTL and velocity. Velocity is fast and a smart way to generate
dynamic pages but  it is not as comfortable as JSTL is. You have to implement
many things which exist in JSTL and other taglibs already. If you use the
macro stuff it will be easier but still a lot work to do.
Kind regards,

Setter method signature when using the 'indexed' parameter of 'ht ml:checkbox'

[Markus . Malmqvist]

   Hi,

 

I have a checkbox inside a collection which is iterated inside JSP page.
Thus I must index the checkboxes to be able to tell which ones are checked.
However, I have been unable to find out which signature the corresponding
setter method of the actionform should have. I think I have tried all the
obvious ones and more... Could you please help?

 

  --markus

 

RE: Checkboxes inside a list

[Markus . Malmqvist]

   Hi,

According to my log printings the setter for the checkbox boolean was never
called even if there was checked checkboxes. Is this caused by the fact that
the setter for the boolean is embedded inside the list and the setter in the
actionform just sets the list? Should the actionform setter do something
else? At least now the actionform setter is not called. 

It is kind of logical actually, the framework should reach into the list and
call the correct setter for each item. Obviously a setter that sets the list
itself does not help at all. It was just that without really thinking about
it writing symmetrical getter and setter seemed logical. Now it feels quite
stupid indeed. I should have read that book further...  :-)

Well, after few trials with different setters I managed to find out that
while you can get a boolean array, it only reports the checkboxes that are
checked, and is thus useless without position info. I am almost sure that
the 'indexed' parameter of the 'html:checkbox' tag would enable position
info. However, I am unable to figure out what signature the corresponding
setter should have. I have several, and none of them is called... Is there
some document that would enlighten me, or could you please help? I would not
like to try to look it up from the sources... Another option would be to use
'multibox' tag instead, as suggested by a person.

I think the ActionForm contents are not relevant now, only the proper
signature for the setter matters. JSP itself seems to be working perfectly.
It generates HTML there checkboxes are differentiated by name, as it should
be in HTML. I could always rip the information straight from the request,
but I would rather use a setter and the form instead.

Sorry about rambling at the beginning, at least you can view my not so
impressive learning process.  :-)

Was that for all the checkboxes - or just the ones that were not ticked?

Can you show us a snippet of the actionform and the generated html?

   Hi,

 

Is it possible to have checkboxes inside a list? I tried this and the table
in the JSP was rendered fine and the getters of the list elements were
called correctly. However, after pressing submit the setters were not
called, and thus the checkbox values were not transmitted into the bean.

[a little bit OT]struts and velocity

[Markus]

Hi 
I've tried to install velocity with struts.
I followed the installation instructions from velocity.
Put velocity-1.3.1.jar and velocity-tools-1.1-beta1.jar in my lib.
copied toolbox.xml and velocity.properties in my WEB-INF
canged web.xml to


 
velocity
   
org.apache.velocity.tools.view.servlet.VelocityViewServlet

toolbox
/WEB-INF/toolbox.xml

10
  
...

velocity
*.vm
  


and I've writen the following velocitypage:



First Velocitypage


#set ($hello="Dies ist meine erste Velocitypage")
$hello
$msg.get("hello")
$msg.exists("hello")




velocityservlet renders $hello but it did not find the message 
the ressources to the messages is right, I've tested it with a JSP

Any suggestions?

Kind regards,
Markus

Re: AW: newbie and html:form

OK, let's give a try!
The HashMap is stored in the session scope? Is it right?
If so, you can reach it in the whole session, in every action or jsp without
adding it as request parameter.

Modifiable GUI elements inside a collection

[Markus . Malmqvist]

  Hi,

 

I have a curious problem. I have a LinkedList which contains records with a
checkbox and some fixed text fields. The value of this checkbox does not
seem to transfer from the browser GUI into server bean. The bean contains
the whole list of elements. All the non-modifiable text fields display
correctly, and if I set the checkbox boolean in the server side the box will
be correctly checked in the browser. Same kind of thing happens with
modifiable text field, information passes from server to browser, but not
from browser to server. I am quite confused, since all seems quite logical,
and it still does not work.

Hi,
No, for this solution you can't use DynaForms. 
 You have to write an ActionForm.

HI,
I've tried to solve something like this, but it fails. In this case I've
written a validate method for this special case and I've called
super.validate(). It is much more easier and faster than try to solve it with 
validwhen or
requierdif (if it is possible!).

Maybe you could extend the action for each class you want to display and add

Problem with requiredIf validation

[Markus]

Hi,

we try to concat more than two conditions with requiredIf.
Something like (selectionOne==1 || selectionOne==2) && value ==2
The problem is that it is not clear how the validator evaluates the
expression.
Does anyone having experiences with that.


TIA,
Markus

Re: [Struts Workflow Extension] Any volunteers for furtherdevelopment and maintenance?

[Markus]

Hello Martin,
I've followed the discussion and took a short look over your pages. The
Stuts Workflow Extension 
seems to be an interesting tool and I will take a deeper look in the next
days.
It would be nice if you have time for answering my questions.


Kind regards,

Markus

Re: Struts security

[markus]

Hello,

sorry, my english is not so good, perhaps I haven'g got the point yet
(and I'm new to struts so I don't know if it works).

Every time a user clicks a link ( => call an action ) you want to check
if the user has the permissions for this action and if the user has not
the permission show an error page? In my opinion that solution is not so
good, especially for users :)

Perhaps you can do the following:
1) Code a login-Page
2) During login-action fill a java bean with all actions a user can
perform
3) Build your view based on this java bean

So users only see the actions they are allowed to perform.

Regards,
Markus

Re: common-logging, Struts, Log4j

[Markus Holzem]

By default the property-files
 commons-logging.properties
 log4j.properties
are located in the directory WEB-INF/classes
Usually you put them in your workbench in the root of the Java Source 
directory. If you build with ant you simply copy them there from your 
chosen source directory

where I find it? is it physical file?

I dont know why my configuration is not working, although I put the

What else should I specify, or configure to make it to work? I have 
log4j-1.2.4.jar in my WEB-INF/lib/

Should I set any system propreties? or web.xml? or struts-config? 

In my classes I am doing that:
 protected static final org.apache.commons.logging.Log log = 
org.apache.commons.logging.LogFactory.getLog(this.class);

   if (log.isDebugEnabled()) 
 log.debug("getMessage(" + locale + "," + key + ")");

(How can I enable/disable the Debug or Trace?)

Thank you in advance. I am really stuck and I couldnt make it to 
work. I am using tomcat 4.18

log4j.logger.app will inherit the appender from rootLogger, so you can just

Betreff: Double log output from commons-logging with log4j
Hi folks,

I'm hunting for some time the cause, why I get double output lines from
log...
My LogonForm::execute looks similar to:

  public ActionForward execute(
  ActionMapping mapping,
  ActionForm form,
  HttpServletRequest request,
  HttpServletResponse response)
  throws Exception
  {
  System.out.println("LogonAction::execute called");
  // Obtain username and password from web tier
  LogonForm logonForm = (LogonForm) form;
  String userid = logonForm.getUserid()
  //
  Log log = LogFactory.getLog(this.getClass());
  if (log.isDebugEnabled())
  {
  log.debug("User "+userid+" logged on");
  }
  // Return success
  return (mapping.findForward(Constants.SUCCESS));
  }
The output I get is:

...
[DEBUG] org.apache.struts.action.RequestProcessor -   Creating new
Action instance
[DEBUG] org.apache.struts.action.RequestProcessor -   Creating new
Action instance
LogonAction::execute called
[DEBUG] app.control.LogonAction - User A123456 logged on
[DEBUG] app.control.LogonAction - User A123456 logged on
...
Since I get "LogonAction::execute called" only once I'm pretty sure that
execute is only called once. I think it has probably to do with my
commons-logging.properties or log4j.properties, but I really can't spot
what I'm doing wrong:
commons-logging.properties:

org.apache.commons.logging.LogFactory=org.apache.commons.logging.impl.Log4jF

log4j.properties:
# Logger catogory (DEBUG < INFO < WARN < ERROR < FATAL)

I'm hunting for some time the cause, why I get double output lines from 
log...

My LogonForm::execute looks similar to:

   public ActionForward execute(
   ActionMapping mapping,
   ActionForm form,
   HttpServletRequest request,
   HttpServletResponse response)
   throws Exception
   {
   System.out.println("LogonAction::execute called");
   // Obtain username and password from web tier
   LogonForm logonForm = (LogonForm) form;
   String userid = logonForm.getUserid()
   //
   Log log = LogFactory.getLog(this.getClass());
   if (log.isDebugEnabled())
   {
   log.debug("User "+userid+" logged on");
   }
   // Return success
   return (mapping.findForward(Constants.SUCCESS));
   }
The output I get is:

 ...
 [DEBUG] org.apache.struts.action.RequestProcessor -   Creating new 
Action instance
 [DEBUG] org.apache.struts.action.RequestProcessor -   Creating new 
Action instance
 LogonAction::execute called
 [DEBUG] app.control.LogonAction - User A123456 logged on
 [DEBUG] app.control.LogonAction - User A123456 logged on
 ...

Since I get "LogonAction::execute called" only once I'm pretty sure that 
execute is only called once. I think it has probably to do with my 
commons-logging.properties or log4j.properties, but I really can't spot 
what I'm doing wrong:

commons-logging.properties:
 
org.apache.commons.logging.LogFactory=org.apache.commons.logging.impl.Log4jF
actory

log4j.properties:
 # Logger catogory (DEBUG < INFO < WARN < ERROR < FATAL)
 log4j.rootLogger=WARN,Console
 log4j.logger.org.apache.struts.action.RequestProcessor=DEBUG,Console
 log4j.logger.app=DEBUG,Console
 # Appender Console
 # Pattern: level, category, message
 log4j.appender.Console=org.apache.log4j.ConsoleAppender
 log4j.appender.Console.layout=org.apache.log4j.PatternLayout
 log4j.appender.Console.layout.ConversionPattern=[%-5p] %c - %m
Both are stored in the WEB-INF/classes directory.

Can anybody give me a hint?

Thanks, Markus

Re: Validator problem with integers

[Markus Holzem]

Hi Brad,

use mask instead of integer. That should do the job. Error message 
states, that the entry is invalid. BTW, arg1 has to be used both for 
minlength and maxlength since {1} is the argument in the error message.

I found that mask can solve nearly all validation problems if they are 
constrained to one field. If you have interdependent fields you still 
have to go back and implement ActionForm::validate.


 
 
 
   
 mask
 ^[0-9]*$
   
   
 minlength
 4
   
   
 maxlength
 4

Brad Plies wrote:

Hi folks,

Using struts-RC2, when using Validator with a dependency
on "integer" validation, I have a problem with the validator
assuming that any integer starting with zero "0" is
necessarily octal.  In one example, I have a form where
people enter phone numbers.  Which is split up into 3 text
boxes.  Area code, 3 digits, last 4 digits.  A fairly common
way to break it up.
Here is the validation.xml entry for one such field:


  
  
  
  
maxlength
4
  
  
minlength
4
  

Numbers like "0897" will cause the "... must be an integer" message.
Obviously it is not a valid octal number, and I know that the format
of these numbers would appear as an attempt at an octal number.
How do you prevent octal interpretation but still ensure that
the field is numeric?  I'm being a tad lazy here, because I
know I could always write my own pluggable validator, but
I'd like to use what already exists if possible.

Re: Singletons in Tomcat

[Markus Holzem]

I usually story Singletons in the ServletContext which is unique for
an application. I often think that ServletContext should be better
named ApplicationContext because that is actually what it represents.
I don't feel comfortable to leave Singletons hanging around on static.
variables. The benefit of ServletContext is, that you can easily
participate on the lifecycle of the ServletContext
(ServletContextListener::contextInitialized and ~::contextDestroyed)
and take appropriate actions when your Singleton acquires any system
resources.

Struts 1.1 on z/OS with WebSphere Application Server 4.0

[Markus Holzem]

Does anyone have experiences with Struts running on an IBM mainframe?
I'm particularly interested in WebSphere 4.0 (z/OS, *not* z/Linux).
I've tried to find anything in the archive, but I only found
references on WebSphere running on Wintel, Linux or Solaris. Since
WebSphere on z/OS is only 99.9% compatible to the other platforms
I'm a bit anxious about giving it a try.
I'd be very much obliged, if anyone could give some hints for running
Struts 1.1 on this platform.

Forwarding to dynamic action

[Markus Pedratscher \(WebBS\)]

Hi,
I am struggling with an action forward problem.

My application has a baseAction which is the parent of some of my actions.
It checks if a user is logged in. If the user is logged it the child action
is executed.

If the user is not logged in it takes the user to the login form. For now I
store the originally requested action, i.e. I store request.getServletPath()
+ "?" + request.getQueryString() in a session variable (not good I know) and
if the login is successfull I want to take the user back to the originally
requestd action. I don't want to use forwards to do this as I would have to
list all my secure pages in struts-config (global or action forwards).

What I want to do it to 'redirect' the user from one Action to another
Action by using something like 'mapping.findForward("/myAction.do?x=y&u-r")
from within my loginAction.

Any ideas on how to do that with struts or a workaround?

Thanks for your help.
Markus

RE: How to access ActionErrors from within FormAction

[Markus Pedratscher \(WebBS\)]

The problem is that if I want to display the error in a Javascript 'alert'
box
I don't want the html header and footer, I just want the message.

The problem with this is to get the error text *only*. The only way I've
found is
to use

String error = RequestUtils.message(pageContext,
"org.apache.struts.action.MESSAGE",
"org.apache.struts.action.LOCALE",
"errors.login.detailsInvalid");

That works fine in a jsp but I don't want this logic in my jsp and
I can't access pageContext from within the Action.

Does anyone know how to get the error text (access application.properties)
from within an Action.

Thanks for your help,
Markus

Why is this an issue?  Just to put any error.header or error.footer in

If you must, the following will get you the list of errors:

 ActionErrors ae = (ActionErrors)
request.getAttribute(Action.ERROR_KEY);

That is exactly my problem. How can an Action class populate a form bean before 
the form bean is created?

:-) Ok, that is the "do all in the jsp"-way. Isn't there a way to read the form 
bean's propertys directly in my db bean? The form bean is somewhere in my 
session, right? Or request? Just wondering it it works.

BTW: I implemented it now using the struts way you mentioned. It works fine.

Will, thanks for your quick response.

Ok, that is a good idea. I will try it. You are right: My way is not the
struts-like way to do it.

But still: Is there no way to get data out of the FormBean? Somewhere in
my JVM this FormBean exists, and somehow I should be able to read data from it.
Or am I wrong?

How to communicate between JavaBean and Struts ActionForm Bean?

[Markus Herrmann]

Hello Struts users,

i have a JSP whose form data is stored in an ActionForm bean (as it should be). 
The ActionForm bean sets the form data to default values (e.g. it gets todays 
date). The JSP not only displays the form, but also displays data which comes 
from a DB bean. In the JSP I use the  tag to associate the DB bean 
with the JSP. The DB Bean connects to a DB and writes the data into a Vector, 
which is displayed by the JSP using the  and  tags. 
No problems until now.

Now i would like to select the data in the DB bean depending on two propertys 
in the ActionForm Bean. How can my DB bean read propertys from the ActionForm 
bean?

Note that until this point no user intaraction happens. This JSP is the entry 
point of the application. I decided not to post the whole code here, because i 
do not think that this helps to understand and answer my question. Correct me 
if i'm wrong.

Thanks for any help in advance!

Re: Help : Dropdown List

[Markus Garscha]

Hi!

i started to use struts only a few weeks ago. i try to connect castor
(http://castor.exolab.org, a persistence module) and struts. i often
have following case:

public class A {
  private B b;

  public void setB(B b);
  public B getB();
}

public class B {
  pivate String description;
  pivate C something;

  get...
  set..
}


and a manager-class which handles A,B :

public class Manager {
  
  public A getA();
  public void setA(A a);

  public ArrayList getAllB();

}

my goal is to work with struts html-taglib, so i can handle Objects in
(e.g.) html selections. the current problem is that struts works over
String-classes to identify the selected value. 

it would be better if struts can handle different classes (get and set
them) and gets a property (e.g. "description") which is shown within the
dropdown (select) list.

any suggestions how to realize such a wrapper?

thanx
markus

RE: servlet-mapping not available

[Markus Skyttner]

If you have apache and tomcat set up on the linux box, your problem could be related 
to how tomcat is configured to run with apache.

Often tomcat and apache are set up so that servlets are required to live under the 
"/servlet" URL-mapping at your server, therefor try this in your web.xml-file:

action/servlet/do/*

instead of

action/do/*

or, if you really prefer *.do, try (in the -tag) /servlet/*.do rather 
than *.do!

Hi!

after developing a web-app locally I tried to get it run on our linux
server.
Unfortunately the servlet-mapping (*.do) seems to be unknown to the server,
so it comments the mapping home.do as unknown (requested url not found).

web.xml and struts-config seem to be valid.

We already have a web-app running on our server that is an organizer we have
bought. maybe i should handle this fact properly - as far as i know,
tomcat's server.xml seems to be valid, too.

Direct requests to jsps work. All classes and the struts are working.
I'm using struts with tomcat 3.2.1 and apache.

Any idea what the matter is? Please help.

Re: internationalisation

[markus . plattner]

Hi Damien,

it's rather simple - struts does this for you.

The only thing you have to considere about is "how to change the 
language", because struts internationalization is based on a Locale
stored in the Session context (Attributename: Action.LOCALE_KEY).

And don't forget to set the locale=true parameter in your web.xml file. 

At first struts tries to detect the proper local from the Request data and 
set's it to the Session Attribute mentioned above if it is not already 
set.

hope it helps

Hi gurus!
I use helper methods that log a warning when a null is
returned - makes it easy to track down errors.
Q1 - Is this good practice? I suspect I'm replicating
logging that struts already has.
Q2 - Are there problems with such methods being
static(will they be a bottleneck)?

Frank - your concern about run-time errors is very
true. I was thinking of using logical names with a
prefix (say gfd=Global Forwards, fbn=Form Bean) so I
can scan my source code & compare the results with my
config file. Not hi-tech & breaches the java standard
of having nice clean names but if I get one more time
waster caused by a mis-match of names I might start
doing it). Just occured to me that it'll help me  find
unused things as well.

Independently from Struts, you have to change the MIME-type of your

I have a form where the user can add and delete values in a collection (by
submitting the form with different params). When they are done
adding/deleting they can hit a 'save' button to invoke an action to save
the data to a database and display a results page.

But if the user hits the browser back button, the last action they invoked
on the data entry screen is invoked. If it was an add, another item is
added to the collection, which although wrong is harmless.

If it was a delete, then an exception array out of bounds is thrown because
the collection no longer contains the previously deleted value.

How can I prevent the user doing a double add/delete? Do I need to use a
transaction token?

RE: =?ISO-8859-2?Q?Newbie design question - How to use properly use a connection pool in the b=

[Markus Massak]

if you have a central dbmanager bean (handling the connpool)
which each object can "see" because it is a singleton, the
db beans can access it. this has nothing to do with servletcontext
and even less with view. it's communication between model (db beans)
and controller (dbmanager). you also can see dbmanager as model.

Content-Type: text/plain; charset=iso-8859-1
From: <[EMAIL PROTECTED]>

I am trying to stick with the MVC paradigm and keep separate the model from
the view.  As the Struts User Manual suggests, I am writing the business
logic as Javabeans (not EJB), these beans are used by the JSP pages.  I
would like to have all of the data
base work done within one bean and have other beans closer to the view use
that bean to do the actual selects and updates/inserts.  This would be easy
if the db bean opened a db connection each time it was instantiated, but to
be able to effectively use a
 connection pool, it would need to persist (like a servlet).

The problem I am having is how would I give the other beans access to this
db bean that has the connection pool?  I was thinking I could maybe put the
db bean into the ServletContext to give it 'app scope', but then those other
beans would still be unable
 to access it since they don't have access to anything that has to do with
the view.  What I am considering is having the beans used by the JSPs store
the connection pool and then when they need to access the database they
could create the db bean object
and pass it a free Connection to do its work...

Any suggestions?

Thanks,
Kenny

RE: Broadvision 6.0 and Struts

[Markus Skyttner]

The group I am in has too tried this and found the same problems as
Nicholas. From these and other reasons we are now moving away from
BroadVision entirely.

If I were to make a strategic decision now (having two years of
BroadVision development experience) I would try to avoid getting into
those problems. 

I agree that the reference struts BroadVision sample applications in
BroadVision 6.0 are very poorly designed.

In my humble opinion, a pure strutsified application running under
Tomcat is faster (and easier to develop and less error prone) than the
equivalent solution running on expensive BroadVision software. That's
what we have found in some small tests we have done. I don't know
exactly why, but I suspect the reason may be buried somewhere deep in
the BroadVision software??

Hello,

My group has just been creating a small example application using Struts
and
BV 6.0. Our plans are to use it in a larger project if it works well. 

So far we have run into a few problems. BroadVision has customized many
of
the Struts tags and provide their own struts.jar. (Actually, they seem
to
provide two slightly different ones, but I can't find any documentation
on
how they are different.)

An example problem is that BV has created their own version of the
html:form
tag that automatically tacks on the BV session ID and engine ID to the
query
string and as hidden values. I haven't figured out how to get rid of
these
(for example if you'd rather use cookies so pages are bookmarkable). 

I've also not been able to get the simple html:base and html:link tags
to
work properly. The tags actually generate hrefs which are missing the
gateway name...

I tried to use the standard Jakarta Struts library, but I cannot get it
to
work with BV 6.0. (The errors I get seem to indicate that BV 6.0 has
incorporated an earlier version of tomcat that doesn't support some
features
needed by struts - like removing attributes from request scope.)

I have to agree with SPE - the sample BV applications using Struts are
very
poor examples, although the Marketplace app (which comes with Business
Commerce) is probably their best example. I notice, however, that they
don't
use html:link or html:base anywhere...

How does bean:define work?

[Wittwer Markus]

Hi!

The bean:define tag simply exposes a bean as a scripting variable by adding
it to the page context:

// from DefineTag.java
pageContext.setAttribute(id, value, inScope);

Now one can access the bean by 

Value of title: <%= title %>

I did the same within a custom tag I wrote but I cannot directly access the
bean as a scripting variable:
 // the tag retrieves some key and stores it
in the bean "title"

Value of title: <%= title %> 
causes an "Variable title not defined" exception,

but

Value of title: <%= pageContext.findAttribute("title").toString() %>
works fine.

Before anyone asks: I have to use scriptlets, because I want to nest the
output within another struts tag.


Thanks for your help,

Markus Wittwer

Trouble is, they put the wrong slide show into the archive.  The code
examples are correct and include Struts, Tapestry (Richard's favorite, I
think), and xsltaglibs.

Richard didn't seem to like Struts too much, but shows it anyway.  He took a
lot of time to show Tapestry.  It's a replacement for JSP and my impression
is that it uses Action Listeners better than any Servlet I've seen.  But
maybe I made that up because I was falling asleep during that part of the

Regarding step 1, you are correct.  I had it wrong.  The jar files must be
used.  This might explain why the .TLD files weren't moving over.

If this is correct, step 2 may not be necessary.  But to clarify, Step 2 had
a typo, and wasn't clear to begin with.  Sorry about that.

It should read:

2. Move:
o strutsblank\WEB-INF\classes\*.* to strutsblank\src
o strutsblank\WEB-INF\*.tld to strutsblank\src

Again, the purpose of moving the .tld into src was to make sure they got
included in the .war.  If I had the open tools wrong, this would explain it.

Anthony,

I am trying to implement your solution and need some clarification on steps
1 and 2.

Step 1 question -
The instruction that come with the downloaded files from Borland
(Nostruts.zip & webinfextension.zip) indicate that the "JAR" files need to
be placed into "c:/jbuilder5/lib/ext" which is different from your
instructions which say to place the "ZIP" files in the directory. I have the
ZIP files in the directory but I am wondering if I missed something here?

Step 2 question -
The instruction "Move: strutsblank\WEB-INFclasses to strutsblank\src". So I
created "strutsblank\" and "strutsblank\src" directories under
"C:/jbuilder5/jakarta-tomcat-3.2.1/webapps/", then extracted (unzipped) the
"struts-blank.war" to the "strutsblank\" directory. Next, I moved
"\strutsblank\WEB-INF\classes" to "\strutsblank\src\classes", is this

Subject: JBuilder w/Struts Support


Here is my recipe for JBuilder5 w/Struts Support.  These steps are a
culmination of a variety of posts found on a variety of groups.  Thanks to
all who contributed to this, for there are many.  I hope these steps work
for everyone.  And I hope Borland eventually adds better support for JB5
w/Struts in the near future.  The .TLD is the biggest problem, and it's not
even a Struts specific requirement.

Ingredients:

o Borland JBuilder5 Enterprise (not tested on other versions)

o Struts Support Addin
Nostruts.zip & webinfextension.zip
http://codecentral.borland.com/ goto JB5 x OpenTools

o Struts Blank .war file
struts-blank.war http://jakarta.apache.org/struts goto
downloads

Steps:

1. Download/Install the above:
o Extract the Struts Support Addin files to the open tools
directory.  Usually it's c:/jbuilder5/lib/ext on Windows.
o Extract the Struts Blank file to your webapps directory.  This
allows it to run outside JB5  For example, the path would likely be
C:/jbuilder5/jakarta-tomcat-3.2.1/webapps/strutsblank on Windows.  You can
call it whatever you want, but JB5 doesn't like dashes in the project .jpx,
so I took it out.

2. Move:
o strutsblank\WEB-INFclasses to strutsblank\src
o strutsblank\WEB-INF\*.tld to strutsblank\src
o You'll see...

3. In JB5, set up Struts Support Addin
o Tools | Configure Libraries...
o New...
o Name: Struts Support Addin
o Location: User Home (default)
o Add... c:/jbuilder5/lib/ext/Nostruts.zip
o Add... c:/jbuilder5/lib/ext/webinfextension.zip
o Click OK

4. Set Up Struts (still in Configure Libraries)
o New...
o Name: Struts v1.0 Release (or whatever version you have)
o Location: User Home (default)
o Add... path.to.struts.jar
o Click OK
o Click Required Libraries Tab
o Add... Struts Support Addin
o Click OK

5. Start a new project in JB5.
o File | New | Project

error in MultipartIterator

[Markus Pallo]

Hello,

i have found an error in the method createLocalFile of MultipartIterator.
If the uploaded file contains a \r\n\n sequence there will be a wrong carriage added.

The sequence \r\n\n will change to \r\n\r\n.

The cutCarriage flag will be remembered from the last read if 
readBytes will be 0.

The following diff contains the fix

Index: MultipartIterator.java

newbie: Error 500 No action instance for path /login could be created

[Markus Roghani]

I'm using struts-1.0-b2 with tomcat 3.2.1.

I wrote a simple login skript like the logon skript in the
struts-example. After I submit my form-data to login.do, I've got the
error message:
Error: 500

Location: /testapp/login.do

No action instance for path /login could be created

I can't find what caused this error. My login application is almost
the same as the logon application from the struts-example.

How odd, because I am 100% sure that the getResourceAsStream works fine for
us in 3.5.3! We used to have a patch for it when running 3.5.2, but all of
us removed that patch when we upgraded, and it still works. I believe that
we are using a system DTD though, but not because it didn't work otherwise.
Oh, and we're running the advanced version of WAS.

On the other hand, I'm not too surprised since we are experiencing strange
behaviours with WebSphere every day. I sincerely think that just about any
other application server out there must beat WebSphere in terms of
productivity and ease of development. Is there anyone out there that has
positive experiences from WebShpere?

RE: WebSphere problem

[Markus Torpvret]

We're running struts on WebSphere 3.5.3 and don't have any problems parsing
the config file. We have not made any modifications at all to the
ActionServlet class, it runs just fine out of the box.

Maybe you could turn up the debug and detail init args to the ActionServlet
to get a more specific trace, it's kind of hard to see what's going on. Are
you sure that there's nothing wrong with the config file?

On a side note:
The only exception I've had during init was due to the fact that we had no
web.xml file. Since that particular message seems to be missing from the
ActionResources.properties file in struts 1.0 beta1 it was kind of hard to
find... It cleared up fine when I created an empty web.xml file (or rather
one containing )

Why does Struts try to read web.xml? Shouldn't that be left to the servlet
container? All init information is stored in the WebSphere database, so we
don't really need a web.xml file...

RE: Struts with IBM VisualAge for Java

[Markus Torpvret]

We're running Struts 1.0-beta-1 with WebSphere 3.5.3 (the new fixpack 3) and
it works pretty well out of the box. We're not using VisualAge though.

Getting Struts to Work with Weblogic 5.1 SP6

[Markus Meissner]

Hi,

has anyone gotten any of the recent nightly builds of Struts 1.0 MVC 
framework to work with WLS 5.1 sp6?

Any suggestions would be helpful.

Thanks,
Markus
