Re: how to access tiles defs in inserted jsp ?

[Michael Muller]

After another evening of flailing, I managed to make this work in a 
rather inelegant way:

In myPageTemplate.jsp, I added this tag:

tiles:importAttribute name=foo scope=request/

and I changed myBodyImpl.jsp to say:

foo = %= request.getAttribute(foo) %

This works, but I'mnot very happy with it.  Does anyone have a better 
solution?

i tried this, and got the following error in my jsp:

Error - tag.getAsString : attribute 'foo' not found in context. Check 
tag syntax'

I had to change the tag to say

tiles:getAsString name=foo /

since attribute is not an attribute of getAsString.

Subject: how to access tiles defs in inserted jsp ?


How do I access the value of a tiles setting from a JSP that is 
inserted into a template?  For instance, in the following scenario, I 
want a rendering of myTilesPageDef to say bfoo = bar/b, but 
it just says bfoo = /b.  I've tried some ugly hacks, which in 
addition to be ugly, didn't work.

Help!

Thanks,

tiles-defs.xml:

  definition name=myTilesPageDef path=myPageTemplate.jsp
put name=body value=myBodyImpl.jsp /
put name=foo value=bar type=string /
  /definition
myPageTemplate.jsp:

  btiles:insert attribute=body //b

myBodyImpl.jsp:

  foo = tiles:insert attribute=foo /

Refreshing screens

[Mohan Radhakrishnan]

Hi

This is a question about the best practice followed when refreshing
screens to reflect new data in the database.


1. View 1 has a 'search' button.
2. The searched records are displayed with a hyperlink for editing
them.
3. The edit page opens a new JSP. After editing the first page is
shown again.
4. The edited values will not be reflected until the 'search' button
is clicked another time in the first page. The records are in the scope in
the presentation tier.

What is the popular practice for this ? It is something like yahoo
mail that doesn't refresh the screen
automatically.

Do I call the same 'search' action every time I edit a record so
that the user need not click the button ?

Validation of user input depending upon the user locale.

[Sagar A. Phanse]

Hi!
I need some help.
I have a textfield in my JSP where user can enter the text.
Now I wanted to validate the user entered text into the textfield such that when 
jsp-form is submitted it will let only those characters to be entered in the textfield 
which are 
belonging to the language/locale of the user.. Depending upon the user locale.
E.g. If user is in Japanese Locale and if user enters ä or ü (german characters) it 
should be validated giving an error.
Is there any fascility available in struts for this?
If there is any other way than struts to achive this, even then do let me know.

-Thanks in Advance
Sagar

Tiles - Support for conditional composite?

[Richard Tomlinson]

I'm evaluating a possible Struts-Tiles solution but require clarification to the Tiles 
approach to page composition.

My requirement is that a potential web user could be categorised as an individual, a 
small business, a corporate, etc.   All categories of users have access to the same 
pages but the content may be different for each category of user.  The differences 
could be as small as a single content area or it could be a different template with 
differing areas.  From initial appearances Tiles assumes that the composition is 
static with respect to specifying the individual content areas.

A poor solution would be to generate lots of different Tiles defs for all combinations 
and employ complicated routing to each.  Likewise, generating a virtual site for each 
category of user leads to similar complications and duplication.

We have a propriatary, non-Struts/Tiles soluton (But of a remarkably similar approach) 
which has addressed all of these problems though we need to ensure that any other 
solution will have similar functionality to what we have already.

So, my questions are:

o  Is this type of functionality currently available?   

o  Has anyone thought of this before and is there a well known solution?

o  Is there any plan to extend Tiles to offer conditional composition?

Regards
Richard Tomlinson

Passing parameter to another Action class using POST

Hi,

I need to pass some parameters to another action class from my action
class. I can do it using query String. But how can I send the parameters
using HTTP POST programmatically ??

Query strings also have some maximum length and my parameter values can
get pretty lengthy.

1 simple way

You can set the attribute in the request as well.
String string1 = Stuff ;
request.setAttribute(Info, string1) ;
Then later in the other action class, just do :

String output = (String)   request.getAttribute(Info) ;

RE: Tiles - Support for conditional composite?

[Navjot Singh]

hi richard,

Well, tiles are great as they allow to create and define your template
definitions in xml files that can be changed easily.
One may follow the simple jsp includes way but usually i prefer tiles.

Your problem goes into conditional tiling.
In terms of typical web applications, these conditions rarely go beyond
roles. You may choose diff conditions. But i will take role example :-)

__Baseline__
What you can have is a common tile for all roles but then you can use core
taglibs.

__How__
c:choose
c:when test=${param.role == 'user'}
t:put name=left_panel value=/jsp/left_user.jsp type=page/
/c:when
c:when test=${param.role == 'corp'}
t:put name=left_panel value=/jsp/left_corp.jsp type=page/
/c:when
  .
  .
  .
/c:choose

I am pretty sure that you can move this check to 1 single file IF
+ roles are clearly defined and
+ the number of areas in page, that can change, are NOT TOO MANY.

Do let us know whichever you way you decided to choose.

HTH

Reusable Components

[Frédéric Dreier]

Hi,

I really need your help and hints... I was not able to found something
related on internet.

how can i make reusable 'high-level' components? taglib seems to be useless
for such components (that already use JSP's and actions). Tiles is exactly
what i need but it does not seems to work if sub-component JSPs are packed
in a JAR library..

Does anyone has some link or other resources about it? or even has another
solution?

Thanks in advance,

snip
But isn't there a way to send POST data programmatically ??
/snip

Servlet API 2.3 supports the HttpServletRequestWrapper class so you could
subclass and create one of these that returns the parameters you want. The
tricky bit will be in having it used for the forwarding. You will probably
need to play round with the RequestProcessor for that.

An alternative is to forward to a page that writes out a form with hidden
fields and submits to the other action but this involves the client side.

 I have the same problem. I solve it by deleting the data-sources section
and some Action in the struts config file.

 It's the only way I can solve the problem, but it's not a solution,
because I need the data-sources and the actions.

 After reading the net, the problem can also be due to xml parser, so I try
to change the XML parser, but the problem is still present.

 So, I'm lost on the way to find to solve the problem.

 I will try with another Server, like jboss and see...

Subject: Converting an ActionError to a string programmatically


Hi all.

I am looking for a good way to turn an ActionError into a string, without
having a
PageContext or anything else so useful (so I can't use the
RequestUtils.message()
function).

Is there a simple way to do this?  I can probably do it the hard way, by
digging
through the RequestUtils source and working out what it does, but I'm hoping
that
either (a) there is another utility class I've missed that will do this, or
(b)
someone else has done this and can save me the pain!

The reason I need this is that I have some code that updates a back-end
system, and
returns ActionErrors if there are any validation failures.  Usually this
gets called
from a struts action, and the errors get displayed to the user with the
errors/
tag.

However, now we need to do some background batch updates, called from a
thread
spawned from a servlet (which is outside our normal struts pages).  The
batch process
is likely to be slow, and so we want the results of any validation failures
to get
logged to an error file, rather than getting displayed to the user.

Any suggestions?

Re: ClassCastException using the DynaValidatorForm

Don't you just love caching? The number of errors I have made like that 
which drove me insane until whatever it was - the browser, the server, 
the memory - stopped caching. Torture.

Did you also close the browser window you were using to test?  IIRC, 
Tomcat
serializes session data when you shut it down.  Just a guess, but I think
you had a session sitting around with the old form bean, and since the
name was the same, it got used.  If you had changed the name from the
beginning (myForm2) you likely never would have seen this.

 Thanks Sean, 
 
 I looked at it and it does avoid the BIG limitation posed by the
 standard spec in fact. Still I cannot use it since it disables the
 passing of the principal identity through calls to EJB methods.
 
That's what it says in the introductory documentation, but...

You're using JBoss/Tomcat right? Well give me a day and I'll email you a
class that should do all you want... It's a RealmAdaptor for
securityfilter/Jboss that uses the JBoss security extension and so
correctly instantiates the Principal for the EJB layer. It works for me
with JBoss4/Jetty, so you should give it a try. (I'm waiting on some
code from another guy whose done similar and so just want to compare -
if his stuff doesn't arrive shortly, I'll send mine as it)


 Now, I am new to the web development and it amazes me that such a basic
 feature is missing from the Servlet spec and is not addressed. Why is it
 that way? Is it so unusual to want to have the login fields on the start
 page??

Not unusual at all... And many Java sites have it that way, but they
don't necessarily use container authentication and they probably don't
use EJB's (many people steer clear - deep seated reservations from 1.0
are still abound).

If I get time I'm going to try and get the Jetty guys to 'surface' their
web Authenticators to allow developers to roll their own... I've looked
at the code and shouldn't be too difficult - one or two areas I'm not
sure about, but...

  Hi,
  
  My question is a bit off Struts but still since I am using Struts and
  it's too urgent for me I thought to try my luck here, maybe someone
 had
  stumbled on this issue too.
  
  I am running JBoss/Tomcat/Struts using the JAAS for handling the
  application security aspects. I have used the
  auth-methodFORM/auth-method clauses inside the Web.xml file.
  
  In my web site I want to have the site home page to have also a small
  login form where the user could enter username and password and login
 to
  the site. The home page, contains other links as well, which lead to
  other parts of the site or even to external pages on other sites.
  
  From what I've read so far, it seems to me that the FORM method is
  activated only when the web user tries to access a protected page.
 Then
  the Web Server (Tomcat in my case) returns the loginPage stated in the
  Web.xml file, and only after the login is performed (j_security_check)
  the Tomcat then redirects the web user to the original portected page.
  
  Is it possible to have the site home page as the login page still
 using
  mechanisms of FORM and JAAS? If so I would really appreciate any help
 on
  how to do it, and what are the configurations required. 
  
  Thanks,
  Erez

Re: Design question: Confirm action after validation ?

[Adam Hardy]

I have an Action base class which all my other Action classes inherit. 
In the execute() of this base class I check whether the user clicked 
cancel, before I call the child class execute().

I presume it would be easy enough to store the originating URL in the 
session, and if cancel is clicked, roll your own Action Forward back to 
this URL.

Since it is all in the base class, it could work for every action as 
long as you are careful to watch the parameters or ids.

Re: Design question: Confirm action after validation ?

[Shashank Dixit]

Hello Adam

I have one doubt. 

You have base action class for all your subaction classes.
What is the responsibility of this base action class.
Do your base action class checks which button is clicked?
If there are say 10 buttons in one form (say, GO, ADD, SAVE, NEXT, etc)
are there 10 if statements in your class. Or it
is sub action class resposibility to check this.? are there 10 or (any no)
of if statements in subaction classes.?
How to eliminate those if statements? any idea?

Pls reply

RE: Tiles - Support for conditional composite

[Navjot Singh]

hi richard,

I thought there is only part of the area that would differ based on roles --
user/corp/xyz
It seems your entire page will be different. In that case it does make sense
to

+ avoid tiles
OR
+ keep separate tiles for diff conditions.

My example works good only if 1/2 of N sections of the page are required to
be changed based on conditions.

hope i am clear ;-)

Re: Design question: Confirm action after validation ?

[Adam Hardy]

my base action class sorts out all the general objects and variables 
that the child actions need - this is the child action's execute() 
signature:

public String executeList(ActionMapping mapping,
  ActionForm form,
  HttpServletRequest request,
  HttpServletResponse response,
  BlackSailUser user,
  Locale locale,
  MessageResources messages,
  ActionErrors errors,
  Connection conn)
throws Exception
I guess the list of responsibilites for the base action superclass is:

(1) establish the action to carry out (your GO, ADD, SAVE etc) which is 
a token that is set by any of a request parameter, request attribute, 
action mapping parameter, or cancel button.
(2) get a jdbc connection object from pool
(3) get message resources from request
(4) get locale from request
(5) get user object from session
(6) get errors from request
(7) error handling  (I don't have any in my subclasses)
(8) get any lists for drop-down boxes (a seperate call to subclass)

Had to check that out by looking at the code. It served me fine since my 
first struts app.

[SCAFFOLD] StorageBeanBase feature request

[Umberto Nicoletti]

I am in the middle of the process of defining the data access layer to 
be used for a new Struts-based application, for which we already use 
Scaffold's ProcessBeans.

We decided not to go with Hibernate as a persistence layer (to my 
disappointment) and to choose Scaffold Access/StorageBean approach instead.
Reading on this list I found an email by Ted Husted saying that he was 
(maybe still is?) not happy with the StorageBean deployment.

So my question is what should I do? I quite like the Scaffold data 
access layer and more importantly my DBA trusts it too.
I'd prefer to go with StorageBeanBase, but in this case I should make 
minor modifications to the Scaffold code (which I will give back to the 
community of course). The other option is the Access approach, but it is 
deprecated and it is not nice to compile an application with lots of 
warnings.

The modifications I have to introduce in the StorageBeanBase are:

replace all calls to

StatementUtils.executeUpdate(null,etc);

with:

StatementUtils.executeUpdate(getResource(),etc);

and add a static String resource=null; with getters and setters
that can be overriden by subclasses. This is motivated by tha fact that 
I have tables located in many different schemas/db hosts and want 
ConnectionAdaptor to return the right connection for that schema/db host.

Thank you,
Umberto

RE: NestedIterateTag won't let go of collection

[Edgar Dollin]

There is a known bug if the collection is passed in directly (i.e.
%=myCollection%).  If the collection is passed in as a bean in the
session, at least certain tags handle it correctly.  The other thing to try
is to disable tag pooling ($TOMCAT_HOME/conf/web.xml --
enablePooling=false).

 Using: Struts 1.1
 Servlet Container: Tomcat 4.1.24
 
 In the process of studying the memory footprint of my

 garbage collected even though there were no apparent 
 references.  The biggest culprit was a rather large 
 collection that was being displayed using nested:iterate.  
 
 I am mentioning *how* it is being displayed only because 
 JProbe revealed that the reason the collection isn't getting 
 free'd is because the associated NestedIterateTag object was 
 maintaining a reference to it - even after the user session 
 was invalidated.  
 
 I realize that this may not be Struts-issue per se but one of 
 how Tomcat manages (reuses) tags.  Have you seen such 
 behavior and is there a way to coerce tag to free the 
 application object?

Then each row is identified somehow (indexed?). Each row will need to
have 
that checkbox named (property) exactly the same way on each row, but you
can assign a different value (suppose index value) to the checkbox of
different row. Your form that accepts values from html request will need
to have String [] property that will be filled with indexes of checked
rows upon submission.

RE: how to upload files to the server

There is an example on struts site called struts-upload.
It is well commented, so try it out. If you can't find it
let me know and I will email it to you directly. The file

Re: Tag inside a tag

[Kris Schneider]

Kishan,

That's the expected behavior of the tag. If you use disabled=true, it will
output disabled=disabled. If you use disabled=false it won't output anything.

Quoting [EMAIL PROTECTED]:

 
 My apologies, It works (the text is disabled) although it prints
 disabled=disabled

 Kris, the solution of using equal tag is not working. The html in the page

 I do not know why it is writing disabled=disabledwhen I am giving it

 logic:equal name=form property=textDisabled value=yes
html:text property=name

 It is not able to convert properly the struts html tag to html tag.

   disabled=true/
 /logic:equal
 logic:notEqual name=form property=textDisabled value=yes

 /logic:notEqual
 
 Standard Struts w/request-time expression:
 html:text property=name

 disabled=%= rt expr that evals to true of false %/
 
 Struts-EL:
 html-el:text property=name

disabled=${el expr that evals to true or false}/
 
 And probably a few others...

Struts upload problem

[J.Broeking]

Hi there,

i have a problem with the struts upload. We need to upload files larger than
1 MB.
We currently use Struts 1.1.b2. I have recompiled the struts classes - this
works fine.

In the upload example und web-inf i modified the struts-config.xml file as
follows:

 !-- This is where you set the maximum file size for your file uploads.
   -1 is an unlimited size. If you
   don't specify this here, it defaults to -1. --
  controller maxFileSize=-1 /

Normally i thougth i now would be able to upload file larger than 1 MB, but
this doesn't work.
We have changed or tomcat port from 8090 to 80. Does this has any influence
on the upload?

help needed!

best regards

Jens

 I guess the list of responsibilites for the base action superclass is:

 (1) establish the action to carry out (your GO, ADD, SAVE etc) which is
 a token that is set by any of a request parameter, request attribute,
 action mapping parameter, or cancel button.
 (2) get a jdbc connection object from pool
 (3) get message resources from request

 (5) get user object from session
 (6) get errors from request
 (7) error handling  (I don't have any in my subclasses)
 (8) get any lists for drop-down boxes (a seperate call to subclass)

 Had to check that out by looking at the code. It served me fine since my

Use of ActionForms with ActionForwards - seems to be a non starter...

[Brook, Andy]

Hi all,
I cant seem o get a form to be passed through an ActionForward to a
target Action.
 
Previously I had multiple Actions, and forms were submitted fine.  I've
migrated the multiple action types I had into a single Action class to
be more maintainable, and replaced existing action class names (in
struts-config.xml) with ActionForward instead.  
 
Now, the validate() method of the associated form gets executed, but the
form does not get passed on to the target 'dispatcher' Action, I get a
null form within the dispatcher Action.
 
Is the use of ActionForms and ActionForwards not mutually compatible, I
think I've missed something somewhere.  Perhaps ActionForwards are for
routing only and don't handle form submission...
 
Any clarification appreciated!
 
Andy.

Re: Design question: Confirm action after validation ?

[Adam Hardy]

I plan on using EJB but haven't got that far yet. At the moment I am 
using a bunch of 'factory' classes as my model, and would like to 
isolate this layer from the request, response objects etc in the actions.

So the fact that I get the connection in the base action is a legacy 
thing - I thought about changing it and probably will soon, to a 
strategy where the actions don't see the connection.  I changed the 
database configuration so that the pool is a JNDI resource, but I 
haven't got around to this second bit yet because the interface between 
the actions and the factories requires more thought as to how I marshall 
the data across.

I am thinking if there is a generic way by which I can achieve this
functionality.
I also realize that I might end up making scope=session for
every form, in trying to implement this requirement. (and I am
worried about this too).
Any ideas, pointers and/or thoughts will be very useful.

RE: Validation of user input depending upon the user locale.

I agree.  What you wants sounds like it would cause more harm than good.
Just my humble opinion though.

Hi!
I need some help.
I have a textfield in my JSP where user can enter the text.
Now I wanted to validate the user entered text into the textfield such that
when jsp-form is submitted it will let only those characters to be entered
in the textfield which are
belonging to the language/locale of the user.. Depending upon the user
locale.
E.g. If user is in Japanese Locale and if user enters ä or ü (german
characters) it should be validated giving an error.
Is there any fascility available in struts for this?
If there is any other way than struts to achive this, even then do let me
know.

-Thanks in Advance
Sagar

The file is present.

In fact I have two files
1. validation-rules.xml
2. validations.xml

The error is occurring only for the first one.
The second file is being read without any problem.

I even removed all the code in validation-rules.xml and left only the following code:
form-validation
 global
  /global
/form-validation

Still the error persists!!!

many thanks for keeping up with my questions - appreciate it. And yes

 I looked at it and it does avoid the BIG limitation posed by the
 standard spec in fact. Still I cannot use it since it disables the
 passing of the principal identity through calls to EJB methods.
 
That's what it says in the introductory documentation, but...

You're using JBoss/Tomcat right? Well give me a day and I'll email you a
class that should do all you want... It's a RealmAdaptor for
securityfilter/Jboss that uses the JBoss security extension and so
correctly instantiates the Principal for the EJB layer. It works for me
with JBoss4/Jetty, so you should give it a try. (I'm waiting on some
code from another guy whose done similar and so just want to compare -
if his stuff doesn't arrive shortly, I'll send mine as it)


 Now, I am new to the web development and it amazes me that such a
basic
 feature is missing from the Servlet spec and is not addressed. Why is
it
 that way? Is it so unusual to want to have the login fields on the
start
 page??

Not unusual at all... And many Java sites have it that way, but they
don't necessarily use container authentication and they probably don't
use EJB's (many people steer clear - deep seated reservations from 1.0
are still abound).

If I get time I'm going to try and get the Jetty guys to 'surface' their
web Authenticators to allow developers to roll their own... I've looked
at the code and shouldn't be too difficult - one or two areas I'm not
sure about, but...

  Hi,
  
  My question is a bit off Struts but still since I am using Struts
and
  it's too urgent for me I thought to try my luck here, maybe someone
 had
  stumbled on this issue too.
  
  I am running JBoss/Tomcat/Struts using the JAAS for handling the
  application security aspects. I have used the
  auth-methodFORM/auth-method clauses inside the Web.xml file.
  
  In my web site I want to have the site home page to have also a
small
  login form where the user could enter username and password and
login
 to
  the site. The home page, contains other links as well, which lead to
  other parts of the site or even to external pages on other sites.
  
  From what I've read so far, it seems to me that the FORM method is
  activated only when the web user tries to access a protected page.
 Then
  the Web Server (Tomcat in my case) returns the loginPage stated in
the
  Web.xml file, and only after the login is performed
(j_security_check)
  the Tomcat then redirects the web user to the original portected
page.
  
  Is it possible to have the site home page as the login page still
 using
  mechanisms of FORM and JAAS? If so I would really appreciate any
help
 on
  how to do it, and what are the configurations required. 
  
  Thanks,
  Erez

When the Struts webapp is not at the root of the server

[Doyle, Michael J]

Hi,

I have been working on a Struts based web application. Things have been
going fine developing on http://localhost:7001/myStrutsApp
http://localhost:7001/myStrutsApp . I've discovered a problem when I
deploy to http://www.somehost.com/somepath/myStrutsApp
http://www.somehost.com/somepath/myStrutsApp . 

Struts gets confused with the paths it generates to Actions and rewritten
URLs. It seems that Struts assumes the web application is always at the root
of the server, e.g. http://www.somehost.com/myStrutsApp
http://www.somehost.com/myStrutsApp . 

It produces 
form action=/myStrutsApp/myaction.do

when what I need is 
form action=/somepath/myStrutsApp/myaction.do

Thus, the html:form html:base and any other tag that rewrites the URL
don't work properly in this configuration.

Is there a workaround for this? Perhaps something to do with module
configuration? The web server is Netscape 3.5.1 and the app server is
Weblogic 5.10 sp13.

Thanks for any help,
- Mike

[OT] JSTL

I've never used JSTL before, and I'm not sure exactly what it is.  Is it
built into standard JSP technology (thus usable without any add-ons), or is
it a tag lib that you have to download and put in your project?

Try logging what is in this cancel parameter

calling isCancelled()

Actually I've just realised I'm suffering the same problem. I'll try it 
myself. Let me know what you find as well!

RE: When the Struts webapp is not at the root of the server

[Doyle, Michael J]

The web server fronts the app server. Locally, during development, I call
directly against the app server. For deployment, I must go through a web
server. It sends requests to root/somepath to the root path of my app
server. Thus, the actual path to my resources is
root/somepath/myWebApp/whateverresource. (FWIW, I deploy as an expanded
war, though I can change that if it fixes this problem.)

Works ok until you get the Struts url rewriting which doesn't know about
somepath. I'm hoping there's a way to make Struts know about somepath.

Thanks,

Re: [SCAFFOLD] StorageBeanBase feature request

[Ted Husted]

I'm not using the SQL parts of Scaffold in new development. For new 
development, I'm now using Hiberate.

I'm away next week, but later this month, I'll apply some outstanding 
patches to Scaffold, and look at providing a direct alternative to the 
SQL package using either Commons SQL/Dynabeans, the new Mapping package 
in the Jakarta Commons sandbox, or Ibatis. There are just too many other 
likely alternatives now to keep this package alive.

Of course, you can always check-out the code yourself and use as part of 
in-house development.

The Access paradigm is not strongly linked to the StorageBeans. 
Essentially, it's just a facade, and you could use anything you like 
behind the facade. (Say Hibernate, for example.)

-Ted.

Umberto Nicoletti wrote:
I am in the middle of the process of defining the data access layer to 
be used for a new Struts-based application, for which we already use 
Scaffold's ProcessBeans.

We decided not to go with Hibernate as a persistence layer (to my 
disappointment) and to choose Scaffold Access/StorageBean approach instead.
Reading on this list I found an email by Ted Husted saying that he was 
(maybe still is?) not happy with the StorageBean deployment.

So my question is what should I do? I quite like the Scaffold data 
access layer and more importantly my DBA trusts it too.
I'd prefer to go with StorageBeanBase, but in this case I should make 
minor modifications to the Scaffold code (which I will give back to the 
community of course). The other option is the Access approach, but it is 
deprecated and it is not nice to compile an application with lots of 
warnings.

The modifications I have to introduce in the StorageBeanBase are:

replace all calls to

StatementUtils.executeUpdate(null,etc);

with:

StatementUtils.executeUpdate(getResource(),etc);

and add a static String resource=null; with getters and setters
that can be overriden by subclasses. This is motivated by tha fact that 
I have tables located in many different schemas/db hosts and want 
ConnectionAdaptor to return the right connection for that schema/db host.

Thank you,

Include response in the JSP page

[Affan Qureshi]

Hi,
I have a JSP page which needs to dynamically include response from actions
(or servlets) which are actually images streamed over the response. I tried
to use jsp:include href=/someAction.do / but I guess it has some problem
for extensions other than jsp and html. (I saw a similar bug for Tomcat
bugzilla). I have tried to define a mime-type for 'do' in web.xml but does
not help. I guess I cannot use bean:include  for the purpose.

Any suggestions?

Also another question, can I get request Attributes set in this page in the
action/servlet that I call thru jsp:include /?


Thanks,
Affan

Try the validationQuery tag so that the pool validates the connection

There is a known bug if the collection is passed in directly (i.e.
%=myCollection%).  If the collection is passed in as a bean in the
session, at least certain tags handle it correctly.  The other thing to try
is to disable tag pooling ($TOMCAT_HOME/conf/web.xml --

 Using: Struts 1.1
 Servlet Container: Tomcat 4.1.24
 
 In the process of studying the memory footprint of my 
 application, I found that certain objects were not getting 
 garbage collected even though there were no apparent 
 references.  The biggest culprit was a rather large 
 collection that was being displayed using nested:iterate.  
 
 I am mentioning *how* it is being displayed only because 
 JProbe revealed that the reason the collection isn't getting 
 free'd is because the associated NestedIterateTag object was 
 maintaining a reference to it - even after the user session 
 was invalidated.  
 
 I realize that this may not be Struts-issue per se but one of 
 how Tomcat manages (reuses) tags.  Have you seen such 
 behavior and is there a way to coerce tag to free the 
 application object?

Re: [SCAFFOLD] StorageBeanBase feature request

[Umberto Nicoletti]

Thanks Ted,
I already generated an in-house version of Scaffold with my patch, but 
got into another trouble.

I got my StorageBeanBase working, but get ResourceExcptions when 
executing findCollection(), which in turns call getCollection.
What I see is that the prepared statement is closed before the 
collection is populated from the ResultSet.
So when ResultSetUtils call getMetaData() the resultSet throws 
SQLException: connection closed.

What am I missing? Please bear with me, even though I am posting on the 
wrong ml (but I knew you were here).

Code snippet from StatementUtils:

public static final ResultSet executeQuery(
Connection connection,
String command,
Object[] parameters)
throws SQLException {
Statement statement = null;
PreparedStatement preparedStatement = null;
ResultSet resultSet = null;
try {

if ((parameters==null) || (parameters.length==0)) {
statement = connection.createStatement();
resultSet = statement.executeQuery(command);
}
else {
preparedStatement = connection.prepareStatement(command);
for (int i=0; iparameters.length; i++) {
preparedStatement.setObject(i+1, parameters[i]);
}
resultSet = preparedStatement.executeQuery();
}
}

finally {
try {
//
//   WHY ARE YOU CLOSING THE STATEMENT HERE
//   CLOSING THE STATEMENT HERE RELEASE THE RESULTSET TOO...
//
if (statement != null) statement.close();
if (preparedStatement != null) preparedStatement.close();
}
catch (SQLException sqle) {}
}
return resultSet;

} // end executeQuery

Thank you in advance,
Umberto

I'm away next week, but later this month, I'll apply some outstanding

in the Jakarta Commons sandbox, or Ibatis. There are just too many other 
likely alternatives now to keep this package alive.

Of course, you can always check-out the code yourself and use as part of 
in-house development.

The Access paradigm is not strongly linked to the StorageBeans. 
Essentially, it's just a facade, and you could use anything you like 
behind the facade. (Say Hibernate, for example.)

We decided not to go with Hibernate as a persistence layer (to my 
disappointment) and to choose Scaffold Access/StorageBean approach 
instead.
Reading on this list I found an email by Ted Husted saying that he was 
(maybe still is?) not happy with the StorageBean deployment.

So my question is what should I do? I quite like the Scaffold data 
access layer and more importantly my DBA trusts it too.
I'd prefer to go with StorageBeanBase, but in this case I should make 
minor modifications to the Scaffold code (which I will give back to 
the community of course). The other option is the Access approach, but 
it is deprecated and it is not nice to compile an application with 
lots of warnings.

The modifications I have to introduce in the StorageBeanBase are:

replace all calls to

StatementUtils.executeUpdate(null,etc);

with:

StatementUtils.executeUpdate(getResource(),etc);

and add a static String resource=null; with getters and setters
that can be overriden by subclasses. This is motivated by tha fact 
that I have tables located in many different schemas/db hosts and want 
ConnectionAdaptor to return the right connection for that schema/db host.

Thank you,

Struts and inter-application messaging

[douglas reames]

Good morning,

BACKGROUND:
I have a struts application that needs to:
[a] Process a request within its own context.  Output:-  string to add 
parameters to URI path:  SQL=SELECT no, product,   vendor_no FROM table 
WHERE no=103,

[b] Append parameters string from [a] to URI - that forwards control for 
future processing outside of Struts app.  Output:-  
http://same-server:8080/cocoon/excel-reports?SQL=SELECT no, product, 
vendor_no FROM table WHERE no=103, and  finally

[c] Forward request to external application to complete processing sequence.

PROBLEM:
[a] and [b] are no problem.
But when I attempt to Forward the result with a mapping.findForward(URI 
string), I get an illegal argument  exception -  
java.lang.IllegalArgumentException: Path 
http://same-server:8080/cocoon/excel-reports?SQL=SELECT no, product,   
vendor_no FROM table WHERE no=103 does not start with a / character.  
This method, as I now understand it, restricts forwarding to 
intra-application.

I get the same result when using org.apache.struts.actions.ForwardAction.

QUESTION:
What is the Struts way to handle forwarding a request to an external 
application?

Best regards,
Douglas Reames

RE: Struts and inter-application messaging

[Navjot Singh]

think simple.

+ Struts does the job with in 1 context so when you forward for same
application, it works.
+ to forward to external app, use response.sendRedirect(externalURI).

encode the url before redirecting

I've solved my problem. Now you've checked the parameter, check to see 
if the request.attribute is set with
request.getAttribute(Globals.CANCEL_KEY);

For some reason in the RequestProcessor it sets this attribute to true 
when the request.parameter is present. Check it out. This is the one 
that the Action.isCancelled() checks. It has to be not null.

[OT] Use of Static Methods

One of my programmers asked me whether or not it is OK to define helper

doing this?  I should know the answer, but just can't put my thumb on it

Odd, I can't reproduce that in 1.1-rc1.  Unless you're
extending something which might override the
isCancelled(HttpServletRequest) method, or the
html:cancel tag is not contained within an html:form
tag, I can't think of anything else.

Re: problem with dbcp and database restart

[Dan Tran]

Meissa,

When your database restarts, all your dbcp connections (in the pool) become
staled connection.

In order to resolve this problem, dbcp needs to do a ping to database server
to make the connection is still up before giving to your app.

Looking into dbcp configuration doc, it should have a param you can setup
(something like QueryString) where
it should be a select statement to a database table.  You many need to setup
a dummy table just for this purpose.

Hope this helps.

Subject: problem with dbcp and database restart



 hi all,

 I have a problem with my configured datasource using dbcp.
 I have posted this question to tomcat user list in vain...
 Maybe some struts user could help.

 I've configured my dbcp connection pool  in Tomcat 4.1.18
 server.xml file.

 here is an extract of it
 ResourceParams name=jdbc/intranetMail
  parameternameusername/namevalueXXX/value/parameter
  parameternamepassword/namevalueXXX/value/parameter
 parameternamedriverClassName/name
   valuecom.sybase.jdbc2.jdbc.SybDriver/value/parameter
 parameternameurl/name
  valuejdbc:sybase:Tds:s198000SGD1:5000/intranet_mail/value/parameter

 parameter
   nameremoveAbandoned/name
   valuetrue/value
 /parameter
 parameter
   nameremoveAbandonedTimeout/name
   value60/value
 /parameter
 Everything works fine. But
 when our database server is restarted, I have to restart Tomcat
 in order to aquire connection to my defined pool.

 I wonder if there is a manner to avoid restarting Tomcat when
 the database server is restarted.

 I have added the parameters below to my pool config.

 parameter
   nameremoveAbandoned/name
   valuetrue/value
 /parameter
 parameter
   nameremoveAbandonedTimeout/name
   value60/value
 /parameter

  I recognize ,I've added that quite blindly.
  Can someone confirm me if this is a cure to my problem ?

  any suggestion is greatly appreciated.

RE: [OT] Use of Static Methods

There is nothing taboo about writing static methods. They are good in

That will keep you safe. As there is only 1 object of the class for which

You may change the behaviour of class in NO time if

RE: [OT] Use of Static Methods

Depends on what you want to do. 'static' classes are loaded, not instantiated.
And you are saying you want to factor out common code and marked as 'static'.  I
cannot think of any reason not to.  Just make sure it's thread-safe.

Note there is a difference between Singleton and static.  Struts Action classes
are singleton.

Re: Cancel button not working?

[Adam Hardy]

Via logging is basically how I solved it - by figuring out where in 
struts I was going wrong.

What it means now is that RequestProcessor is not setting that attribute 
- you don't need to set it by hand, struts should.

It's just one little if clause. According to your logging, 
request.getParameter(org.apache.struts.taglib.html.CANCEL) has a 
value, right? The parameter is not null?

If the parameter is not null but the attribute is null, that means that 
you have either not got the same struts code as me (1.1 final) or your 
RequestProcessor is not executing the processPopulate() method.

I would check 2 things:

that org.apache.struts.taglib.html.Constants.CANCEL_PROPERTY == 
org.apache.struts.taglib.html.CANCEL  (i.e. that the parameter name / 
cancel button name in your HTML is correct)

and that RequestProcessor.processPopulate() is executing. This method 
also puts the data into the action form, so you could use that as a 
check unless you can grab the source code and put some logging in there.

As you can tell I'm intrigued.

I've solved my problem. Now you've checked the parameter, check to see 
if the request.attribute is set with
request.getAttribute(Globals.CANCEL_KEY);

For some reason in the RequestProcessor it sets this attribute to true 
when the request.parameter is present. Check it out. This is the one 
that the Action.isCancelled() checks. It has to be not null.

bean:write and c:out only takes proper javabeans?

[henrik . bentel]

Does the bean write tag and the c:out tag (JSTL) only accept object that
adhere to the Javabean specification?

I have objects with public fields(no getter or setter) and objects inside
objects all public(again no getter or setter).
But if I try to do somthing like(in JSTL) C:out value=
${resultBean.intMember}/ where intMember is just a public int field, I
get the following exception:
org.apache.jasper.JasperException: An error occurred while evaluating
custom action attribute value with value ${resultBean.intMember}:
Unable
to find a value for intMember in object of class beantest.testBean1
using
operator . (null)
 at
org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:254)


Yes, idealy I should use proper javabeans, but in this case my struts app
is interfacing with a CORBA based backend, and all result-structures
comming back are IDLEntities with public fields(the backend is an old
C-based app with nothing but heavily nested enums and structs and whatnot.
).

So my assumption was that the tags used reflection on fields so I could
just write value=${result.innerResult.wayInnerResult.innerLong}
Are there any ways of doing this?

   I apologize if this is a bit off topic, and if it is a

   question.
   I've never used JSTL before, and I'm not sure exactly 
 what it is.  Is
 it
   built into standard JSP technology (thus usable without 
 any add-ons),
 or
   is
   it a tag lib that you have to download and put in your project?

RE: [OT] Use of Static Methods

[David Graham]

 
 One of my programmers asked me whether or not it is OK to define helper
 methods as 'static' - and I realized that I didn't know the answer.  So
 I
 guess the question is, in a web application, can common code be factored
 out
 to a helper class and marked as 'static'?  

Static methods are evil for many reasons including philosophical (they're
not OO) and practical (you can't override their behavior).  You should use
a Singleton class with non-static methods.

Struts' RequestUtils class is a good example of why you should never use
static methods.  Developers want to override their behavior but can't
because everything is static.

David

 Are there any major problems
 with
 doing this?  I should know the answer, but just can't put my thumb on it

Re: tiles and tabs; post instead of link

[Dudley Irish]

I have just finished converting the example from the tiles examples
from links to submits.  It is a little more complex than just changing
the code that generates the links to generate submits, though you have
to do that too.

First let me describe what I was trying to do.  I have a form which
has a number of tabs each of which contains inputs.  So there is the
header of the form that has a few inputs, then several tabs that all
have inputs.  My idea was to use the formbean to carry all this
information around and repopulate fields as necessary.  Please note: I
am not sure this is the best way to do this and I haven't gotten all
of my functionality working, so I will happily take advice on how to
do it.  Given that, this is how I did it.

I started with tabsLayout.jsp from the examples.  Using a tiles
definition like the following:

definition name=.population.tabs path=/common/layouts/tabsLayout.jsp 
  put name=formaction  value=/Population.do /
  put name=focus  value=name /
  put name=selectedIndex  value=0 /
  put name=parameterName  value=selected /
  put name=tabbody   value=/Population.jsp /
  putList name=tabList 
item value=One   link=/filler1.jsp /
item value=Two   link=/filler2.jsp /
item value=Three link=/filler3.jsp /
item value=Four  link=/filler4.jsp /
  /putList
/definition

Notice the addition of formaction and focus.  You must also add
useAttribute takes for these like so:

  tiles:useAttribute name=formaction classname=java.lang.String/
  tiles:useAttribute name=focus classname=java.lang.String/

Then in tabsLayout.jsp you start the form with:

  html:form action=%=formaction% focus=%=focus%

Notice the use of formaction and focus, though I think that focus
might be better off as a form parameter rather than as a tile
attribute.

Next you add

  bean:define id=selected
   name=populationForm
   property=selected
   type=java.lang.String/

to give your Java code access to the form parameter that identifies
the selected tab.  I have not included the details of the ActionForm,
but you do need to add selected to your form.  We will get to how this
is set below.

The following snipet of code is used to check the value of selected.
It shows some modifications that have not been fully tested.  In
particular, I am in the process of removing the selectedIndex tile
attribute.

  %
String selectedColor=#98ABC7;
String notSelectedColor=#C0C0C0;

int index = 0; // Loop index
int selectedIndex = 0;

try {
  selectedIndex = Integer.parseInt(selected);
}
catch( java.lang.NumberFormatException ex ) {
 // do nothing
}
// Check selectedIndex bounds
if( selectedIndex  0 || selectedIndex = tabList.size() ) selectedIndex = 0;
String selectedBody = 
((org.apache.struts.tiles.beans.MenuItem)tabList.get(selectedIndex)).getLink(); // 
Selected body
  %

Then we insert the tabbody, or the header as per the tile
definition.  We have to do this here in order to keep it and all of
the tabs in the same html:form definition.

  %-- Insert the tab body --%
  tiles:insert attribute=tabbody flush=true/

Then we insert the tabs.

  %-- Insert the tab pages --%
  table border=0  cellspacing=0 cellpadding=0
%-- Draw tabs --%
  tr
td width=10nbsp;/td
td
  table border=0  cellspacing=0 cellpadding=5
tr
  logic:iterate id=tab name=tabList type=org.apache.struts.tiles.beans.MenuItem 

  %
String color = notSelectedColor;
if( index == selectedIndex )
  {
  selectedBody = tab.getLink();
  color = selectedColor;
  } // enf if
index++;
  %
td bgcolor=%=color%
input type=submit value=%=tab.getValue()% name=tab/
/td
td width=1 /td

  /logic:iterate
/tr
  /table
/td
td width=10 nbsp;/td
  /tr

This is actually a little simpler than the tiles example.

Next we insert the selected tab:

  %-- Draw body --%
  tiles:insert name=%=selectedBody% flush=true /

And close the form:

  %-- End the form --%
  /html:form

All of this will make more sense when you are looking at the
tabsLayout.jsp from the examples.  Now the final piece the Action.
Here is the code that I have been testing with:

  public ActionForward executeAction(ActionMapping mapping,
 ActionForm form,
 HttpServletRequest request,
 HttpServletResponse response)
throws ClientException, Exception {
String tab = request.getParameter(tab);
PopulationForm popForm = (PopulationForm) form;

try {
  if (tab == null) {
popForm.setSelected(0);
  } else if (tab.equals(One)) {
popForm.setSelected(0);
  } else if (tab.equals(Two)) {
popForm.setSelected(1);
  } else if (tab.equals(Three)) {
popForm.setSelected(2);
  } else if (tab.equals(Four)) {

David Graham wrote:

And the generally accepted way to get a reference to the singleton is 
with a static getInstance method, right?  Is there any way to make an 
anonymous subclass of a Singleton that uses a static method to get the 
instance?  For example:

public class SubclassSingleton {

  public static void main(String[] args) {
MySingleton ms = new MySingleton() {
  int doSomething() {
return 42;
  }
}
MySingleton inst = ms.getInstance();
System.out.println(ms.doSomething());
  }
}
class MySingleton {

  static MySingleton me;

  static getInstance() {
if (MySingleton.me == null)
  MySingleton.me = new MySingleton();
return MySingleton.me;
  }
  int doSomething() {
return 8;
  }
}


This simple code doesn't work, because even if you subclass the 
singleton and override one of the methods, the getInstance() method will 
create a base-class MySingleton.  And since this method is static, it 
can't be overridden.  So while singletons are useful, you can't use them 
in anonymous subclasses (as far as I can tell), which makes them 
difficult to use with mock object unit testing.

Please someone point out the flaw in my reasoning, it has bothered me 
for quite a while and I'd love to be proven wrong.

validator validwhen not working?

[Poon, Johnny]

Hi,

I'm trying to use validwhen, so that it's only valid when either all three
related fields are empty or are filled, it's valid; otherwise not.  ssn_1,
ssn_2, and ssn_3 are the field names.  For some reason, when I put this in,
none of the validation takes place, not even required, minlength, maxlength,
nor mask, which all worked before I put validwhen in there.  Did I do
anything wrong?

Here's the one of the fields in my validation.xml file:

field property=ssn_1 depends=validwhen, required, minlength, maxlength,
mask
msg name=required key=errors.required.enter /
msg name=minlength key=errors.minlength.digit /
msg name=maxlength key=errors.maxlength.digit /
msg name=mask key=errors.mask.numeric /
arg0 key=ssn_1.displayName /
arg1 name=minlength key=${var:minlength} resource=false /
arg1 name=maxlength key=${var:maxlength} resource=false /
var
var-nametest/var-name
var-value( (*this* == null) and (ssn_2 == null) and (ssn_3
== null) )/var-value

RE: [OT] Use of Static Methods

[Yansheng Lin]

I gave this a bit of thought before.  I felt in some situations, static methods
and instances are preferred.  For example, if you want to synchronize a query
method.  Or in some situations where overriding is rare, i.e.,
java.util.Calendar.

 Subject: Reusable Components

 Hi,

 I really need your help and hints... I was not able to found something
 related on internet.

 how can i make reusable 'high-level' components? taglib seems to be useless
 for such components (that already use JSP's and actions). Tiles is exactly
 what i need but it does not seems to work if sub-component JSPs are packed
 in a JAR library..

 Does anyone has some link or other resources about it? or even has another
 solution?


Reusable user interface components is what JavaServer Faces is all about,
and it can be used with Struts:

  http://java.sun.com/j2ee/javaserverfaces/

One of the features is exactly what you're asking for -- the ability to
package up components, renderers, and the corresponding tags into a JAR
file that auto-configures itself when you drop it into /WEB-INF/lib.

 Thanks in advance,

 Frederic

How do you know overriding is rare for any particular class?  Widely used
code such as Java and Struts cannot assume anything about how developers
will want to use the classes so you should always (even for internal code)
make classes as flexible as possible.
