Stuts with OJB how to return Object to html:form tag

[ross]

Hi All,

Have an issue with populating a form from a POJO (Bean like with getters /
setters) returned from OJB

Have setup Struts with ObjectRelationalBridge

Using DynaValidatorForm for validation

Passing objects into DB without issue.

Was hoping to pass the object back to the same form that I am using to
collect input.

Do I need to convert POJO into an ActionForm so it can be seen as a bean by
the form tag??  Can I use the DynaValidatorForm??  Can I pass anthing else
back to the form tag other than an ActionForm?

I imagine there is a simple solution but its eluding me for the moment.

Regards

Ross Rotherham

RE: accessing Attribute of a parent-tile-definition

Bad luck. I didn't succeed with the suggestion of Cal.

I searched the archive for the cited posting. I found it, but it does not fit

I have no Jsp-file where I import a tile and for so I have no place to put the

My tiles reside in XML-files and I use defintion names as action target.

Dynamic multimedia content with Struts...

[Todor Sergueev Petkov]

Hello everybody : is it possible with struts tag libraries to
retrive dynamically for example pictures from a database and place them
on the jsp page on the fly

And also another question : I would like a user to be able to select
from a page certain file names ( dynamicaly generated ) and
then to press a download button -> I want to fetch the requested files
from a database, pack them in one unique zip file and push this to the
user.
Has any of you done something similar... And if not do you think it is
feasable

Thanks,

My thanks go to both Wendy and Shane on this one.  I found a third way to get around 
it, which is closest to my original intent: 

I pointed the global forward to the jsp page called test.jsp (instead of directly at 
the action!).  The jsp page then links correctly to the action using , once

Yes, you can do it without the ".do" and it is safer to do so.
You can even do this which is nice:

...

Note the /test? instead of /test.do? 

I remember looking at the source code before and the URL comes in in pieces so that 
the query string is separate from the path and so struts automatically puts on the 
filter (.do or whatever it may be).

Not sure if you need the .do part but I do and that can be bad if you change the

it.  I will look at mine now to see if I can change it.

I am getting the following error on , which I can't figure out:
HTTP ERROR: 500 Request[/test] does not contain handler parameter named

RequestURI=/clientdb/test.do


I am following a couple of decent examples using the LookupDispatchAction class (pages 
128 -130 in "Programming Jakarta Struts" by Chuck Cavaness). My config is basically 
the same as what he has, but I have a couple of minor differences, which I don't think 
should be causing any issues, but maybe someone can put me right: 
The JSP link that gives me the error is the following: 

My action mappings section has the following action:

I also have a section for the testForm: 



...


My /pages/test.jsp uses a template, which points at /pages/testcontent.jsp, which 
contains the following: 






As u would expect, the "insert.label" key is contained in the properties file (as well 
as the "test.maintain.label"  from the initial link)

insert.label=Insert
test.maintain.label=Maintain Tests



My TestUpdateAction class has the following hierarchy and methods


LookupDispatchAction
  |
BaseLookupDispatchAction
  |
BaseUpdateAction (methods: getKeyMethodMap (),getKeyMethodMap (params), insert 
(params), update (params), delete ()
(Maps "insert.label" to "insert")
  |
TestUpdateAction

My TestForm was generated using Xdoclet from the Test.java source code, and has a 
protected "updateMethod" string variable, with a getter and setter.
TestForm is inherited from ActionForm

The kind of thing that I'm thinking might be causing the issue include: 
1.  The hierarchy of TestUpdateAction
2.  The fact that /pages/testcontent.jsp is not referenced directly, but via the 
following lines in /pages/test.jsp:

3.  The calling link does NOT in a Form.  Its entire contents looks like this: 

<%@ include file="/tags/taglibs.jsp" %>









Can anyone see anything I'm missing, or anything that I'm just doing incorrectly?  
Any help is much appreciated.

redirecting problem

[harm]

Hi all,

In my struts application I need to check if some information is still 
valid. If not then I need to redirect the user to some other page.
The page I need to send the user to is not static. So I need to calculate 
to which page the user needs to be redirected.

In my Action class I would like to do the checking. And redirect the user 
to the correct page.
I cannot use something like this:

return (mapping.findForward("overview"));

because the redirection page is dynamic.

Any ideas on how to achieve this?

Thanks a lot,

Hi;

If I want to initialize an ActionForm from a session bean, what's the

Looking at it it seems to me that I want to tie the session bean to the

RE: Is this a bug with struts config file?

[Richard J. Duncan]

My experience is the same as yours. That while the ".do" can be omitted
in the action definition, it may not be omitted in the forward. FWIW, I
think this is proper behavior. Certainly if you html:link to the forward
your html pages will be do-less. Also, you can change to another scheme
(e.g., "/action/login") simply by modifying the structs-config.

Subject: Is this a bug with struts config file?

 

Short version:

I would think that I could do this then 
and Struts

would know to add the .do for me.  When a  is
rendered it does not

have the .do on it.  I have to make it  

 

Is that a bug?

 

Since Struts determines extensions on the fly (at Servlet startup based
on
URL pattern in web.xml)

it just seems defeating that you would have to hard code an extension
anywhere in the system.

 

 

Longer version: 

In my crusade to wipe out all hard coded ".do" extensions in the app for
future upgradability

(for instance all my links are like this 
instead of "login.do" 

 

I found that (unless something is not right) the global-forwardS don't
act
as I would expect.

It implies in the struts config dtd that if contextRelative not true
then
the path is module relative.

 

It seems minor but if I need to change the extension to ".go" or
something
else,

say, because if a hacker doesn't know you are using Struts because the
extension is ".poo" then

it may help the system.  But in order to make the change I would have to
go
into all my many

struts config files and globally replace ".do".  Not too bad if I am
doing
it but when someone else

in the group with less experience does it then it could be a pain.

Re: method to get new Id to next action when old Id is in request?

[Ted Husted]

When you forward from one action to another, Struts treats it just like 
a new request from the client. If a parameter was used to populate an 
ActionForm from one action, that same parameter will be used to populate 
every other action in the chain that uses the same ActionForm in the 
same scope.

Chaining actions together is generally frowned upon. The primary reason 
is that it indicates that the actions are becoming an API unto 
themselves. This is often a bad idea since the intelligence you are 
putting into these various action is trapped within Struts and the web 
layer and cannot be reused.

The recommended approach is to look at the underlying operations these 
actions are performing, and refactor those operations into a facade or 
set of business objects that all the actions can share. Then, instead of 
chaining actions, have a single action call whatever methods it needs on 
the facade, or instantiate and execute whatever business objects are 
needed. That way you can do whatever you need to do from any action.

The underlying idea is that each Struts action should represent a single 
use case scenario. The scenario requires certain input (the ActionForm) 
and results in certain output (the ActionForward). Interally, the Action 
class should focus on selecting the appropriate business classes, 
handing these external classes whatever input they need, and deciding 
what to next.

Chaining an action often indicates that a business operation is embedded 
in an action. Business operations should be refactored out of the 
presentation tier, and into a business layer that you can control 
without the help of the HTTP protocol.

Of course, your mileage may vary. If you must chain actions (), 
a simple solution is to add a "read-only" switch to the properties you 
want to set and share between actions. Then have the setter check the 
readonly property before changing the value.

if !(readonly) this.value = value;

Of course, this doesn't work with DynaActionForms. The next best thing 
is to add a helper bean to the context and have your actions prefer that 
to the ActionForm property. Something like

String id = fetchHelperId(request);
if (null==id) {
id = myForm.getId();
putHelperId(request,id);
}
(which could be reduced to processHelperId(request,form)).

Incidentally, the reason you have to create a new ActionForward is that 
these are shared by all the clients and all the requests. If you change 
the ActionForward instance returned by findForward, you are changing it 
for the rest of the application as well. (Hence, the freezing.)

So, if you must add parameters to an ActionForward (), a new 
instance must be created and returned by the Actions. (Which is why we 
return the ActionForward and not just the ActionForward name.)

-Ted.

Adam Hardy wrote:
I have two actions chained together. They both take the same formbean. 
The first is sectionInsert.do and the second, which sectionInsert 
forwards to on success, is sectionEdit.do

sectionInsert.do receives the properties of a Section in the request 
parameters, including id=0 where it is 0 because it does not exist in 
the DB yet. So it inserts the new Section into the DB and returns the 
new id, which is needed by sectionEdit to put into the html for the edit 
page.

I originally thought I could save the new id to the formbean and this 
would get passed on, but sectionEdit instantiates its own formbean and 
fills it with the request parameters - include id=0.

Is there an intuitive way of passing on the new id?

I already use sectionEdit.do as a first action by calling it with an id 
on a querystring, where the formbean picks it up. I would like to use a 
method that is easy for both these situations.

I'd appreciate any inspiration.

I don't think you need to put .do.
Actually in the web.xml file you have following code

*.do
  

here you can configure as you want you can configure *.yup also & it works.

Hi.



the ".do" in forwards to actions is necessary because when you make a
forward, the request is processed again by application server,  if you not
add .do in forwards  to struts actions then the application server do not
map the request to action servlet of struts.

Thanks for the response Marty,

I am using Tomcat 4.1.24, and have no problem generally putting these

Where can I find out what the rules are for folders to hold JSPs for

Re: Returning values from a BasicDynaBean in jsp

[Kris Schneider]

I guess my previous example wasn't clearly formatted, but it certainly wasn't
supposed to illustrate executing a query from a JSP. Here's a modified example:

Java (e.g. an action):
--
import javax.servlet.jsp.jstl.sql.Result;
import javax.servlet.jsp.jstl.sql.ResultSupport;
...
ResultSet rs = ...;
Result result = ResultSupport.toResult(rs);
request.setAttribute("result", result);
...

JSP:

RE: Actions Best Practice

[Erez Efrati]

The only thing you cannot do is having a mixture of this solution
(having the action-mapping parameter set to the 'init' or else) and the
one of DispatchAction class that keeps all the operation under the same
roof (class).

That's not necessary. In the action mapping, you can specify the action 
parameter with parameter="init" or parameter="send".

Well, JSTL is just *one* of the Jakarta Taglibs libraries.  If that is the

Re: [APPLICATION SCOPE] -How and Where to store in app scope

[Thomas Cornet]

IMHO, the best thing to do is to create a Plugin, where you'll store all 
what you need to. The plugin init method is executed once while the servlet 
container loads the webapp.

Re: JSTL and Struts-el

[Marco Tedone]

Are you telling me that ${customer.name} it's enough for Struts-el to look
for a customer bean stored in any scope and process a getName() method? If
so, that's great.

Would it be a good approach to have taglibs, jstl and struts from their
respective bundles? I downloaded taglibs (complete version, nightly build)
and I suppose there is something similar for JSTL. This way we are
guaranteed to run always the last versions.

For stuff, mainly in my project I'll need to present bean information and to
cycle through collections, more or less what an enterprise application is
made of, isn't it? One risks to get bored :))

Apache Tomcat web servers

[yan]

Thanks for the advice Hue, you have given me a lot to go on there - much
appreciated.

Do memset.com actually support Apache/Tomcat?  I couldn't quite see a
reference to it under their products on there site.

I have been considering http://www.nameonthe.net or
http://www.joshuainternet.com

Anybody know about them who can comment as to their suitability?

RE: JSTL ot struts taglibs?

[Bailey, Shane C.]

Scriptlets are more powerful (you can do ANYTHING Java can do), faster, is a
standard (it is the Java language you know) and if you are going to spend
time learning a new language (${var} == "pooPoo") then you would be better
off learning Java (assuming you don't already know it) cause then you could
do scriptlets and middle tier coding and more whereas if you use your time
learning JSTL all you will know is JSTL.  

Believe me, JSTL will be easy to replace if someone comes out with an
alternative.  I am a programmer but I understand the importance of having
the tags be similar to HTML tags and not like tags containing scriptlets.

If it makes you happy $var is a legal Java variable name so you could just
write scriptlets with $var and no one would realize you weren't writing JSTL


:)

Why do you think Ant is so popular??? It got rid of all the $var UNIX script
like crap and made it more like tags should be!!!

Bottom line is, yes, Struts tags aren't the best but JSTL is not much better
and will probably be replaced with something not so ugly in the future.


Just my .02 sense.

I like it how some people don't get disturbed by questions about connecting
to a database with JDBC to the Struts user list but get mad if you post a
differing opinion about the crappy way some tags were written that
interfaces with Struts code.  What an ACE!

Definitely JSTL.  They're more powerful, easier to use, potentially
faster, and a Java standard.

Hi Adam,

Yes, maybe - although they're not dedicated tomcat hosting.

> By the way Hue, you neglected to state one very important fact - how

The package we use from memset cost us about £350 for 12 months hosting
(there's 25% off for 12 months in advance) - which I think is a 96MB server
with 6GB disk on a contended 1.5Mbps connection and Debian Linux - it has
performed flawlessly. This works-out at about £30/month. This includes 2 ip
addresses, unlimited domains, unlimited services: DNS, TC, Apache,
PostgreSQL/MySQL, multiple JVMs, MX/POP3/IMAP services etc. etc.

> Maybe you can clear up something else for me - with full root access to
> a virtual server? What is virtual about it? Are you still sharing
> hardware with other customers?

Yes - you do share hardware with other customers as memset use User Mode
Linux, UML - see the following links for anyone not familiar with this
amazing technology:

http://www.usermodelinux.org/ (for the community homepage)
http://uml.openconsultancy.com/ (great link from one who practices what he
preaches! - also offers hosting services)
http://user-mode-linux.sourceforge.net/ (sf project and very good links,
too)

As you might expect from Linux - UML is a very advanced, groundbreaking and
seems an extremely stable and robust technology. It basically allows Linux
to host multiple hosts on a slightly-patched hosting server. Each UML
(virtual server) is totally self-contained and runs a full-blown version of
Linux (with again, only a slightly patched kernel). Almost any Linux package
can be installed on a UML without modification and to all intents and
purposes behaves _exactly_ like a normal server. We have not seen any
situations where any other UML has dominated the host and caused us to run
slowly; also never had a server 'fail' and need hard re-booting; never had a
situation where the virtual server has behaved any differently to a "normal"
server.

For us it works very well - we like flexibility of a dedicated server and we
host several domains and we think we understand Debian Linux pretty well. We
use it for email (qmail) with IMAP/SSL, Apache with mod_ssl (for SSL mode)
and for multiple virtual hosts and Tomcat hosting under each domain and
PostgreSQL for database storage. We could not now envisage going back to
dedicated TC hosting only!

Eeek - yes, very scarey. At least with these types of packages the bandwidth
is unmetered so it wouldn't actually cost you any more money!!!  Ok,
seriously though - yes, this is a big concern, but there are loads of
resources for securing Linux servers and even great tools to test for common
vulnerabilities, common exploits and common ports that should not be open!

But, when I discovered our previous hosting company was running a very
outdated TC installation - at least this way we are in control of the server
configuration. We use long, complex passwords; _all_ maintenance traffic to
and from the server is encrypted: Webmin/SSL, IMAP/SSL, SCP for FTP-type
activities (over ssh); ssh for shell; all services not needed are disabled;
PostgreSQL will only communicate with processes on the local server; Tomcat
runs under a JSM ... the list goes on!  We've tried pretty hard to be
careful - who knows, hopefully we've made it difficult enough that someone
will not waste effort trying to get in. I sleep more comfortably during the
day - knowing we're in control of our server!

Hope that bit more info helps,

H.

Apache Tomcat web servers

[yan]

Hi,

I am trying to find a Web host for my JSP applications, but I am finding it very 
difficult locating a suitable host.  

Anyone know of any good Web hosting vendors who support MySQl, Apache server and the 
Apache Tomcat servlet container?  I prefer a UK based host as this is where I reside.

I have had a response to an enquiry from a hosting company called 'Houxou '.  This is 
what they have replied:

"Assuming Tomcat is "well-behaved", I would have no problem running on our servers, 
but would need to investigate how happy it is to co-exist with two competitors on the 
same machine:

Apache server pages; and 
Sun's Chilisoft ASP"

I am not sure what they mean

Any advice would be gratefully received

(servers hosted in the US/Canada) in the last 6 months after
failure-after-failure with Tomcat - although they apparently supported
tomcat. They felt I was being "unreasonable" if I complained that TC was
down frequently as they claimed their servers were still "up" and serving
static content - so this was fine in their mind - the simple website in
question was finally offline for at least 2 weeks.
We were being blamed for apparent errors in the pages although the website
had not been changed and had worked flawlessly for 3 months prior to this
outtage ... and also worked without changes on a fresh download of Tomcat
and on every configuration of ours: Windows and Debian Linux with IBM, BEA
and Sun's JDKs 1.3-1.4 and under a JSM and without a JSM!
We did attempt to get a refund as we'd paid for 12 months hosting in
advance - but they refused and unless we wanted to get legal they would not
pay up - in the end we transferred to another ISP (easy to do as our DNS is
located elsewhere and enabled us to do this). A *costly* lesson.
The lessons we learned are:

1) Always keep control of DNS records - and allows easily and quickly moving
from a poorly-performing ISP. Ours are with "register.com" - not cheap but
their DNS appears to be very solid and all DNS can be configured online and
DNS costs are included in the domain registration costs. There are plenty of
other options for other DNS providers, though.
2) Never go with an ISP for technologies they "seem" to support - only ever
go with a technology from an ISP if they specialise in this and really know
what they're doing. Recommendations seem to be the key, here -
recommendations for kgbinternet seem to crop-up a lot - I haven't personally
read a bad word about them yet.
3) For JSP specifically - always consider what _could_ go wrong with hosting
and what implications sharing with other sites could have. For instance a
private JVM is a really good idea - from a security, performance and
reliability viewpoint. Also, consider what effect other services running on
the same server could have - for instance we lost tomcat once as, unknown to
us - the server was also being used for users just playing about with
tomcat - another user had deleted their "jserv" directory and this caused
tomcat to fail to start - taking our site with it. We also had problems
wanting to change some settings for the JSM - in order to run Struts/Tiles -
this was finally done - but grudgingly only by the above ISP.
4) Consider what version of Tomcat (or other container) you'd like to be
running and ask whether this is the version they run and how proactive are
they at installing security updates and fixes. When we first investigated
the version running with our ISP it was Tomcat 3.2 beta 4(!) - even though
3.3a Final and 4.1.x was also suitable for production. From the Tomcat bug
database there appeared to be some very serious security problems with the
version they were running: source disclosure, web.xml disclosure etc.!

After trying 4 different shared hosting providers we now use

if you're not familiar with Linux then you may have a stiff learning curve -
but they have excellent and very helpful tech support staff and if you're
running Debian "apt-get install tomcat" gets you a fully-running Tomcat 3.x

Check out the June issue of "Java Developer's Journal" (vol. 8, issue 6),

This is standard JavaBean behavior.  Regardless, I encourage you to use

That's not necessary. In the action mapping, you can specify the action

The question had nothing to do with scriptlets.  It was about using JSTL
or Struts tags.  I'm not going to participate in another JSTL debate.  The
tags speak for themselves.

RE: Apache Tomcat web servers

[Hue Holleran]

Hi yan,

I would be inclined to keep-away from ISPs who do not have good and
*extensively* proven experience with JSP and only go with those who are
specifically recommended to you for JSP. I fell-out with a UK-based ISP
(servers hosted in the US/Canada) in the last 6 months after
failure-after-failure with Tomcat - although they apparently supported
tomcat. They felt I was being "unreasonable" if I complained that TC was
down frequently as they claimed their servers were still "up" and serving

installation - JVM, JSM (Java Security Manager enabled) all correctly setup!

The real advantage is that this allows hosting of multiple domains; full
root access; ability to host email if you need it; ability to choose JVM;
ability to run apache to front tomcat if you want; ability to run own
SSL-enabled service if needed; basically pretty much anything that you can
figure-out how to do it!

The obvious real downside is that with power comes responsibility and the
responsibility is with you to ensure you don't leave the server wide-open to
attack; leave an open mail relay; leave a host that can be commandeered in
an attack etc. etc. But starting with modest objectives and building from
there can get you the service you need without great cost and with full
control - and if you're unsure there are plenty of resources from where help
can be sought.

Hope the above helps,

Nope. I prefer something like:

I can do it your way. It'll cost you $1000, will take

How is submit different from update?  And reset depends on how you do it...
A typical reset button on a form is client-side, it just puts the form back
the way it was when that page loaded.

LookupDispatchAction is good for this... Instead of (or in addition to) the
execute method, you would have methods for (as an example) create, update,
delete, (or whatever the submit buttons on your form are called).  The
getKeyMethodMap() method maps the text on the buttons to the method.

So in one action, you can handle all the things that need to be done on that
form.

As far as going to a different action, a form generally posts to it's own
action, but once the code there is executed you can forward wherever you
want.  Either use mapping.findForward() to look up one of the forwards in
struts-config.xml or instantiate your own ActionForward object and return
that.

RE: JSTL ot struts taglibs?

[Bailey, Shane C.]

Another debate.  Your debate was to make me feel like I was doing something
wrong by posting my opinion.  There was no debate.

The tags do speak for themselves and if you think that $var which Java
allows but is NEVER used is acceptable syntax for a tag then that speaks
volumes as well.

Never said, "JSF will replace JSTL".  I just said let's see what that
technology and others has in store in the near future.  Java didn't have
every API and package when it first came out so, like I said, we will see
what JSF has to offer in the near future.  I'm just hoping it is some
replacement for those step backwards tags.

Re: Returning values from a BasicDynaBean in jsp

[Kris Schneider]

Didn't like the JSTL Result suggestion, I guess ;-). As a JavaBean,
BasicDynaBean only exposes two properties: "dynaClass" and "class" (both are
read-only). So, that's all JSTL can get out of a BasicDynaBean instance. The
Struts tags, on the other hand, leverage BeanUtils/PropertyUtils so they're
perfectly capable of dealing with DynaBean properties. This is the Struts
equivalent to your JSTL snippet, but it'll actually work if "person" is a DynaBean:

Extending Tiles Role Attribute

[Terry Brick]

Hi,
I really need to ability to specify multiple roles in
my tiles tags (using the "role" attribute) like we can
with Actions.  I did a quick text search on the struts
source and it looks like maybe it's using Strut's
RequestProcessor.  In case anyone has done this, I'm
just hoping someone can point be to the right
direction so I can quickly implement something.  Any
pointers?

Re: How to configure commons-logging on JDK1.4

[Kris Schneider]

If you're happy with Jdk14Logger instead of SimpleLog, that's fine. But I just
verified that you *can* get SimpleLog to work with JDK1.4. As I said, make sure
commons-logging.properties is in WEB-INF/classes, *not* a subdirectory.

Yep.
Its interesting to note that one of the major struts development tools
(Camino) was developed here in Singapore (by Scioworks Technologies). Id
imagine that once the recession is over and companies start to spend on IT
projects again we will see even more adoption adoption of struts in the
region.

Of course Id imagine that lack of an IT budget in the current economic
climate was once of the things that has driven many to struts and other open
source solutions, but having now seen the benefit they will probably stick
with it.

That doesn't surprise me.

IMO, the Jakarta Struts framework has become the de facto standard for web
based application development on the J2EE platform.  With more and more
companies (and government agencies) web-enabling their applications, I think
you'll see a steady increase in traffic here.  I still cling to the hope
that by being a "Struts Evangelist" somehow I helped us (even if only a
little) get where we are today.

Another off topic note - With the increased need for professional Struts
Training, I decided to begin offering Struts Training Classes for beginner
through advanced users.  This would be outside the scope of my involvement
with Struts-Atlanta.

Struts-Atlanta is (and always will be) FREE.  The training classes/packages
would not be free and probably not be cheap (costs for instructors and
classrooms are not cheap).  As I said, I haven't formalized the packages
yet, but more info on this will follow.  Email me privately if you (or your
company) are interested.

RE: JSTL ot struts taglibs?

Going by this statement that you replied to and didn't correct anything
about it:

> there's a good chance that (in the future) containers 
> will have their own optimized versions of the JSTL-tags, there are 
> already some
> implemented in TC5.x

It doesn't sound like the optimization is totally there and everywhere.  

Anyway, I'm not saying that scriptlets are the way to go if you reread all
my posts.  I am saying the guys who were assigned to write the JSTL tags (at
least the logic ones) really dropped the ball by appearing to not know their
intended audience (UI specialist which are used to HTML like tags and not
${var} ==).

More of a philosophical disagreement than anything.

I'm sure I'll end up using JSTL but I am hoping for a little better
implementation of some of the tags.  That's all.

Don't be so sure.  Because the JSTL is standard, containers can optimize
the java code generated from JSTL tags.  This means a  tag can be
converted into a real Java if statement instead of creating tag instances
and invoking the tag's lifecyle.  My understanding is that the Jasper JSP
compiler (comes with Tomcat) actually generates faster Java code if you
*don't* use scriptlets at all.  Resin and Tomcat both optimize JSTL tag
usage.

So, with the JSTL we get the best of both worlds:  Fast page rendering and
standardized, powerful and easy to use markup tags.

Isn't "Tata Consultancy Services" an odd name for an IT biz. It sounds like
a cosmetic surgeon's office or something.

Re: Tiles status and feature suggestion WAS accessing Attribute of a parent-tile-definition

[Reinhard]

Not at all. If you use Tiles-controllers, you can dynamically create your 
component-content and insert it in your layout using the attribute-name in 
your tiles-definition. In your Tiles-controller you have all freedom to 
create a dynamic content.

I do it this way and it works well (having many controllers in one logical 
page)

Don't be so sure.  Because the JSTL is standard, containers can optimize
the java code generated from JSTL tags.  This means a  tag can be
converted into a real Java if statement instead of creating tag instances
and invoking the tag's lifecyle.  My understanding is that the Jasper JSP
compiler (comes with Tomcat) actually generates faster Java code if you
*don't* use scriptlets at all.  Resin and Tomcat both optimize JSTL tag
usage.

So, with the JSTL we get the best of both worlds:  Fast page rendering and
standardized, powerful and easy to use markup tags.

RE: [FRIDAY] Impossible requirements & customer expectation management [WAS: methodto get new Id to next action when old Id is in request?]

[Nicholas L Mohler]

My experience...you have to explain the consequences in layman's terms (no
"geek talk", and yes, I am a computer geek).  If you can, instead of
explaining why the software won't work given the requirement, and a
real-life example that the customer can relate to and understand...for
example, it's like trying to tie my shoes when I'm not allowed to have
shoe-laces (I wouldn't use that one).  A good analogy can sometimes go a
lot further that a brilliant explanation.

So what does one do when one has requirements that are (for all practical
purposes) impossible?

How does one actually go about convincing a Customer/PHB/VIP that its
impossible without them thinking one is incompetent and making excuses?

no offence meant James but I've had past experience when the so called
architects and designer of my client have asked me not to use hidden
variables...period...

they would not listen to anything, they would not discuss about and hence
my
question. Obviously you do understand that the answer given by you is
something I cannot tell to my customers but thanks for answering anyway.

That's ridiculous.  If that were true, then just give up and go home.

Re: how to pass a jsp variable to a javascript function

Hi Julie,
what do you get as a result of that iterate? It looks correct. Do you 
have javascript errors?

Hi All,

Can anyone suggest how to pass a jsp variable to a javascript function 
correctly? It is in a nested:iterate block that has an indexId="tmpIndex". 
 what I would like to do is to have the 'y<%=tmpIndex%>' variable pass 
into my JavaScript function.It seems like the server side <%=tmpIndex%> 
variable can not be translated into the client side script function.

Here is my code:





var y<%=tmpIndex%>=<%=tmpIndex%>;







any suggestions?

Very Appreciated.

I am trying to figure out the code in struts.validator.FieldsCheck.java
in order to write one of my own.
Can someone explain what the purpose of the following lines of code in
all of the validateXXX() in Struts:

validateIntRange (...) {

if (isString(bean)) {
value = (String) bean;
}
...
}

Is this really necessary?
