Moving from Struts 1.0b1 to Struts 1.0b3

[Graeme Miller]

Currently having a problem with migrating code from using Struts 1.0b1 to
Struts 1.0b3

Everything seems to work fine apart from the fact that the validate methods
on our form beans (ie subclasses of org.apache.struts.action.ActionForm) no
longer get called successfully.  I have had a look through the release notes
and cannot find any reasons why these methods would no longer work.  

Any ideas people?  The following error is what gets thrown in the tomcat
log.

Re: Managing resource life cycle during request

[Ted Husted]

I doubt that overriding ActionServlet.process() would work. The
controller sends back the response, and it's done. It's then up to HTTP
to deliver the view, usually a JSP. 

Any clean-up routine would have to be the responsibility of the view,
which puts you into the scriplet zone.

[Jeff Trent]

Well, it looks to me that short of overriding ActionServlet.process(), there
is no way one can clean-up resources after the page has been rendered...

Re: Managing resource life cycle during request

[Ted Husted]

Following the rendering? By Struts? None.

It's a straight JSP (or other view technology, like a Velocity
template).

Generally, things go into the request, and are disposed when the request
is disposed.

There's an enhancement to the iterate tag in the works that uses a
RowSet directly.

Re: Managing resource life cycle during request

[Jeff Trent]

That's sounds okay for simple forms, but I'd rather not serialize objects
from a multi-row recordset to a collection every time.  Too much overhead!
Let me put the question another way, in Struts, what method on the form or
action class gets called following the rendering of the input page?  I'll
check source code now for this answer...

Re: Managing resource life cycle during request

[Ted Husted]

The types of objects I use for presentation should be disposed and
garbage collected. Here we would be talking about standard collections
of mainly Strings and maybe a few primitive types. Anything kinky would
be handled in the action. The view gets everything handed to it on a
silver platter.

Just because the objects are held in the bean doesn't necessary mean they

Re: Multipage forms and validation

[Ted Husted]

When the time comes, David's Validation servlet would get my vote.
Unfortunately, we need to get 1.0 out the door before voting on anything
like this. Beta 3 is counting down now, so we only talking a couple of
weeks now.

In any event, what features Struts, or any Jakarta product, will offer
in any timeframe, will always depend on what people contribute. No one
here can say "hey you, go implement this feature". What gets implemented
depends on what people choose to contribute, and David has stepped
forward with a very fine contribution. 

One of things that make it a fine contribution is that the Validator
servlet snaps right into the framework, without altering anything else.
So you're free to use it, or not to use it, or to use something else.
Which is as "Struts-esque" as you can get ;-) So I'd say use it .. I do!

Re: Newbie to struts - jdbc/dbtags

[Ted Husted]

You can configure Postgresql in the struts-config.xml, and then use the
same datasource with the Jakarta Taglibs JDBC. Works like a charm. 

Struts uses "org.apache.struts.action.DATA_SOURCE" as the datasource
identifier (see Action.java).

This is how you do it:










In the above case in yourBeanObject class you will have the method getBeanList() which 
will return a list of your beans. And in the bean class eachBean) you will have a 
method getName() which will return the name variable.

Hope this helps.

Re: Newbie to struts - jdbc/dbtags

[kuma.cra]

Hi,  im a newbie to struts basically applying the examples and reading
the documentation (mvc). I am about to connect a psql datasource
(Postgresql, luinx OS) database to a struts mvc utilizing a database URL
.

Thus is there a ActionForm example and what level if i have to create a
ActionForm class i.e /WEB-INF/classes/custom/ActionForm or can i create
a package above WEB-INF as at the moment i am creating/modifying
examples from the taglib's and packaging them under mt Struts-bbnpa (my
re-named struts app's.

Re: Managing resource life cycle during request

[Ted Husted]

In general, you should put everything you need for the presentation into
a JavaBean, release any other resources, and return just the bean in the
request. This way you also do things like immediately return the
connection to the pool (before anything bad happens). 

As and for an alternative, the Jakarta JDBC tags work great with Struts
too, if you like doing things on the page.

Personally, I use mostly RowSets, which can be disconnected from the
data source as soon as the command completes. The Struts tags don't
support RowSets directly (yet) so I end up pounding the RowSet into a
value object bean and/or an ArrayList for iterate (though a fix for that
is in the works too).

I'm trying to deploy a couple of struts apps on resin which I've deployed

Logic-Iterate

[Shane Warne]

Hi,
I was trying to us the logic-iterate tag and i'm stuck
at a point. Please go thru the snippet below,


  
<%
String myName = instance.getName(mybean.getName());
System.out.println(myName);
%>


Now, how do i get one of the properties of a bean when
i'm iterating through a collection of a bean objects.
Bottom line is i would like to pass the property
getName() into a variable. Can anyone help me in
sorting this out ??

Thanks,

Error compiling 'cannot resolve symbol'

[Sylvie Djihanian]

Hi,
 
I am trying to compile the sample application 
"business.zip" I found in the Struts, an open-source MVC implementation article http://www-106.ibm.com/developerworks/library/j-struts/?n-j-2151.  
I get the following error:
 
[javac]

I downloaded junit.jar and copied it into my

should have come with the Ant binaries).
 
I'm somewhat new to the struts and java world... 
Do you know how I can get the builder to find the junit package?

RE: How do I Internationalize ActionError parameter values?

Use the request argument to get the session and then get the locale out of
the session using getAttribute(Action.LOCALE_KEY). If you have a shared base
class for all of your forms (that extends ActionForm) it might make sense to
put a getLocale(request) method in there.

RE: Any Hashmap examples used in jsp page?

[Deadman, Hal]

I don't think what you are trying to do should be done in the JSP by a
struts/custom tag.

Why not copy the value objects in the HashMap to an array based on the order
of the keys in your String array? Then pass the array to the JSP instead of
the HashMap. If you need the keys and they aren't attributes of the value
objects then you can pass the String array of keys to the JSP too.

"multiple" selectlists

[Dante le Poole]

Hi all,

Can Struts deal with selectlists which allow multiple selections? If so, how should I 
create the accessors methods for the formbean,
i.e. how does Struts get/set the multiple selections from the formbean?

Thanx!

Managing resource life cycle during request

[Jeff Trent]

I was wondering how other people deal with physical 
resource objects (eg. db result sets, etc.) during a request.  Before 
struts, I use to allocate the resource, call request.setAttribute() with the 
resource object, call request dispatcher (to do jsp presentation), then clean up 
the resource back in the servlet upon return.  In struts, this has all been 
abstracted out.  Is there an alternative way to manage request-scoped 
resources like this under struts?

Usually, you can just pick any old WAR and deploy it. No worries, mate.

There's no good reason why one WebApp should affect another (and every
reason why it should not).

Some vendors have started to use Struts as a compatibility test, so you
should be sure to check with PowerTier too.

Getting the locale object is easy. If you are in an Action perform method,
just call:

getLocale(request);

If you are not in the Action class, you can do what that method does,

Locale locale = (Locale) session.getAttribute(Action.LOCALE_KEY);
if (locale == null)
 locale = Locale.getDefault();

Hey,

Looking through the archive I found a couple of notes about
internationalizing the ActionError parameters.  I'm talking about the
following:

public ActionError(java.lang.String key,
   java.lang.Object value0,
   java.lang.Object value1)
Construct an action error with the specified replacement values.
Parameters:
key - Message key for this error message
value0 - First replacement value
value1 - Second replacement value

What I want to do is pass in keys from the properties file into the second
and third parameter.  Specifically I want to pass in the prompt keys to
display to the user the fields that are in error.

One possible solution proposed was by Craig as follows:

The java.text.MessageFormat class (which is how Struts is doing the
substitution) does not support internationalizing the replacement
parameters directly.  But how about doing this in two steps?

* Look up the internationalized replacement value from
  a MessageResources bundle

* Use the returned String as the replacement value in the
  ultimate message.

However, I need to get the locale somehow.  It seems alot easier to just
override ActionError to accept keys as parameters.  Has anyone overridden
the ActionError class to accept "java.lang.String key" parameters instead of
"java.lang.Object value0"?

RE: Null PointerException when run with Apache/SSL/Tomcat

[Deadman, Hal]

This could also be caused by a link URL including the port number which
sometimes caused a new session to be used. A NPE could result when code that
normally expected something in the session didn't find it because the
session was new. As indicated by the other post, this may be fixed in b3.

Ok, good.  The error I am getting is as follows:

How do I Internationalize ActionError parameter values?

[Kyle Robinson]

Hey,
 
Looking through the 
archive I found a couple of notes about internationalizing the ActionError 
parameters.  I'm talking about the following:
 public ActionError(java.lang.String key,
   java.lang.Object value0,
   java.lang.Object value1)

  Construct an action error with the 
  specified replacement values. 
  
  
Parameters: 
key - Message key for 
this error message 
value0 - First 
replacement value 
value1 - Second 
replacement value
 
What I want to do is pass in 
keys from the properties file into the second and third parameter.  
Specifically I want to pass in the prompt keys to display to the user the fields 
that are in error.
 
One possible solution proposed 
was by Craig as follows:
 
The 
java.text.MessageFormat class (which is how Struts is doing thesubstitution) 
does not support internationalizing the replacementparameters 
directly.  But how about doing this in two steps?* Look up the 
internationalized replacement value from  a MessageResources 
bundle* Use the returned String as the replacement value in 
the  ultimate message.

However, I need to get the 
locale somehow.  It seems alot easier to just override ActionError to 
accept keys as parameters.  Has anyone overridden the ActionError class to 
accept "java.lang.String key" parameters instead of 
"java.lang.Object value0"?

Re: visual changes based on state

You can either 

1. Route users to different pages based on their state, or

2. Deliver the current state to the presentation layer in the form of
JavaBeans that the Struts logic tags can test.  ...

Re: Null PointerException when run with Apache/SSL/Tomcat

[Bryan Field-Elliot]

I had an extremely similar (though not quite exact) problem last week. I 
posted as you did, but no one responded. This morning, I upgraded from 
Struts beta-1 to beta-3, and so far it appears to have magically fixed 
the SSL problem. Hopefully a similar path will fix yours too.

Good luck,

 Hi Jon. I'm having a similar problem as Dudley with a HashMap. I tried
playing around with your example but couldn't get it to work within the
context of what I'm doing. Perhaps another example would help. For
example, I have a scriptlet that looks something like:

 fee.fie.fo.sql.ResultSetBean rsb =
(fee.fie.fo.sql.ResultSetBean) request.getAttribute("resultBean");
 java.util.HashMap hm = rsb.getProperties();
 String foobar = (String) hm.get("foobar");
 out.println("foobar = " + foobar);


So, the ResultSetBean contains a HashMap as a property. I get a reference
to the HashMap and then can extract a value with a key as input. Any ideas
on the syntax of doing this with "bean" tags? TIA.

RE: Format on the JSP pages

[Joyce Tang]

Title: RE: Format on the JSP pages





 Michael,


Thank you very much for the response.


However, I have heard about reservation on using taglib from Jakarta just for the purpose of datetime formatting.  It is too expensive to convert your datetime to long, wrap it in context and then use tablig.  Also there will be nested tablib usage problem.

Are there any simpler ways to do it?


I notice there on the to-do list for struts is a task to support PropertyEditor.  Is there any work around when the PropertyEditor support is not there yet.

Thank you very much for the help.

In addition to Craig's comment, if you decide to use the Jakarta Taglibs
project  , you can this on your JSP
page.


<%@ taglib uri="http://jakarta.apache.org/taglibs/datetime-1.0"
prefix="dt"
%>


  
property="startDateTime"/>


In the above example my bean contain the following method


public long getStartDateTime() {
  //
  //  return the Calender.getTime() component;
};

RE: Hidding .jsp files

[Mikkel Bruun]

 Hi Craig,

A blast from the past...I believe this post is a month old...

Anyways...I see your point, but consider this...

If I only refered to the functionaly (pages, actions whatever), I would have
the following problem...

myForm.do forwards to myAction which is validated to myForm...

So if I linked to myForm.do, my GET would be validated and myForm would
return errormessages...

So I need an URL that doesn't trigger any logic, but just shows the form to
the user...(or have a hidden init field in the form)...

One thing to keep in mind is that, in a typical Struts application, the
names of the JSP pages are obscured anyway -- because the form submits
go
to the controller servlet.  For example, walk your way through the
Struts
example application, and note how many of the locations actually shown
have "*.do" extensions on them ...

As a more radical way to hide things (but more for the purpose of
discouraging users from setting bookmarks in the middle of an
application), I've also resorted on occasion to more radical approaches:

* Open the application in a window that doesn't have a location bar

* Create a frameset with only one frame in it (so the location bar
  never changes at all).

Resetting an Action Form (urgent)

[Mikkel Bruun]

Hi Guys, 

Please help me out on this one...

I ran in to a small problem...

1. In the system im developing the user has to go through several pages,
entering information that needs to be processed...
2. When ever the user enters invalid data, he'si returned to the form and is
presented to error messages...
3. The user should be able to press the bacl button, or user other means to
navigating backwards in the process. When navigating backwards the forms
should be populated with whatever data he has entered...

(of course all the above is straight forwrd implemented in struts, but check
this)

4. After the user has completed the entire proces, he is able to do it one
more time. 
This time the forms should not "remember" what the user previuosly entered,
and should therefor be blank...

To give a more substantial example...it could be an insurance broker who
would do several calculations on an house insurance for each customer...
Each calculation should be isolated from each other...

Is there a simple way to do this???

At the moment there no coupling between my ActionForms and my Logic Beans
(ie no association or anything)...

Could I use the transaction token??? and if so, is there any documentation
for the transaction token!!

thanks in advance

Mikkel

If you have a link, you can post it to the User list. 

Or if you want to send it to me, I can put it on my Struts page. 

Depending on the nature of the material, we could then consider whether
to add it to the Users Guide.

Null PointerException when run with Apache/SSL/Tomcat

We are getting a NullPionterException which seems to originate from the the
struts-html tag libraries.  The error only occurs when we run Struts with
Tomcat/Apache and SSL.  If we bypass SSL and just go through Apache (port
80) we do not see the error.  Has anyone else seen this problem when running
Struts through SSL?  Any suggestions would be appreciated.  The error
message is shown below.

RE: Any Hashmap examples used in jsp page?

[Shamdasani Nimmi-ANS004]

Steve,

This is how I used a HashMap in a jsp:










getUserList() method in my user_list bean returns a HashMap.

Hope this helps.

 Hi Jon. I'm having a similar problem as Dudley with a HashMap. I tried
playing around with your example but couldn't get it to work within the
context of what I'm doing. Perhaps another example would help. For
example, I have a scriptlet that looks something like:

 fee.fie.fo.sql.ResultSetBean rsb =
(fee.fie.fo.sql.ResultSetBean) request.getAttribute("resultBean");
 java.util.HashMap hm = rsb.getProperties();
 String foobar = (String) hm.get("foobar");
 out.println("foobar = " + foobar);


So, the ResultSetBean contains a HashMap as a property. I get a reference
to the HashMap and then can extract a value with a key as input. Any ideas
on the syntax of doing this with "bean" tags? TIA.

Having struts.jar in your classpath is actually a bad thing. Search the
archive for the thread entitled "Baffled No More" - it provides a good
technical explanation as to why this is. It could be that the presence of
struts.jar in your classpath is causing your problem. Try moving it to
/web-inf/lib.

struts.jar is in my classpath, this exception is thrown at runtime & there
is no org.apache.struts.example package in my struts.jar, hence my

RE: Wizard form approach

[Lacerda, Wellington (AFIS)]

Never did, but it seems the struts-example gives you some tips on that.

You can define a parameter action or phase that will hold the current phase
on the wizard. Since an Action can have multiple forwards, you can select
the next step based on what is the current one, if the user pressed cancel
or back.

On each interaction you will save a new transaction token on the session.

The form bean can be the same. Or it can be one for each step and then you
make the bookeeping of the user choices.

I think it is quite like that.

Is anyone currently using multiple pages (same ActionForm) in a wizard-esque
manner?  If so, how are you doing validation without knowing the details of
which elements are displayed on which page?  In other words I'd like some
fields to be required without having the user to go back 3 pages.  Thanks.

Generating Dynamic Input Tables.`

I hope this isn't a repeat, but I need a bit of help here.

I have a collection of simple value beans that I'd like to
allow the user to edit.  I don't know how large the
collection is, but the simple bean merely contains a Label
and Value.

I'm trying to do something like the jsp code below. If
there is a simpler way to deal with this I'm open to it as
well.

Thanks in advance!!

Thomas



collBean = The bean containing the collection.
collProp = The property name of the collection in collBean.

Look at the mail archives.  Basically, you carry two extra fields on your

against fields on the CurrentPage.

Is anyone currently using multiple pages (same ActionForm) in a wizard-esque
manner?  If so, how are you doing validation without knowing the details of
which elements are displayed on which page?  In other words I'd like some
fields to be required without having the user to go back 3 pages.  Thanks. 

RE: *TED* Re: I am finding that templates are SLOW

[Deadman, Hal]

Weblogic sometimes has trouble parsing relative paths. Are you using
Weblogic 6.0? It might be fixed in SP2. I do this <%@ include
file="/include/toppage.inc" %> and it works. Try /inc/imports.jsp.

In your action class you have to do lookup/create
for your entity bean usual way. 

After you got your reference ( remote interface )
nothing prevents you to put it into session
context ( or whatever ) of your servlet container. 

Then your jsp can fetch it and do what it like.

hope this helped.

Re: Auto Form/Action Class Code Generator?

[Ajit Joglekar]

Any ideas about how to do this? Tom, JD are you already working on this?

I thought about using JTidy to generate xhtml from the original html and
then to use JDom to access / update the form elements and attributes.

Regards,
Ajit Joglekar.

RE: Confused about Uploading

[Jon.Ridgway]

Hi Peter,

When you start the upload process with web container will store the file in
a temp location. This will vary depending on your setup. The important thing
is that you can access as shown below and then write to a location of your
choosing. This code snippet is an edited version of that found in the upload
example app.

Note file is the DiskFile object..
-

ByteArrayOutputStream baos = new ByteArrayOutputStream();
FileOutputStream fs = new FileOutputStream ();
InputStream stream = file.getInputStream();

byte[] buffer = new byte[file.getFileSize()];
stream.read(buffer);

fs.write(buffer);
fs.close();
baos.write(buffer);


Hope this helps,

Jon

Subject: Confused about Uploading

Hi all,
I am using the struts-upload.war example to upload
files. Everything sorta seems fine except I can't find
the files that I uploaded
Where are they? How can I specify where I want the
permanently saved? 
Better yet, are there any examples of how to store
them in a Db ? 

Thanks a million,
Peter.
