RE: checkbox and iterate problem

[Neal]

I got it working..Thank you for your assistance.

I completely rewrote my code, and instead of using indexed=true, I
constructed the property inline using <%= blah %>
I'm not sure why I couldn;t get it working the first way, but now it works.

RE: checkbox and iterate problem

[Neal]

I'm afraid you've lost me, I thought the propery HAD to be boolean for a
checkbox.
Can you please send me a code snippet of what you have working (even if
its different then what I am trying to do).

High level: I just want to read a list a of strings items from a DB, and
then populate a form with the items and let the user select them or not.

Thanx

RE: checkbox and iterate problem

[Neal]

I changed everything from boolean (primative) to Boolean (Object type), no
difference
I still see the same behavior.
After submit my setter function is not called.
but for a non-indexed checkbox it is called.

However the getter() is always called.

RE: Struts - vs XSLT (ASP.NET v. Struts)

[neal]

Yeah I think youre right on one levelthat JSP is more directly
comparable to XSLT than Struts...except I was also referring to Struts'
declarative tag syntax for logic. Earlier in the thread we were talking
about how it is beneficial to make the presentation template declarative
syntax only. That is something where Strut's tag libs are more comparable to
XSLTbut ultimately I suppose tagLibs are a part of the JSP spec though
so ... alright fineyou are right.  ;-)

Nonetheless, it is interesting to know that Struts does not explicitly
dictate use of JSP.  So the controller is maliable enough (without having to
pick through the open source code to change stuff) to do a transformation
rather than a forward?  That's interesting to note.

As Joe said, Struts doesn't mandate JSP.
A more appropriate comparison will be

JSP vs XSLT

In this regard, both are scripting-oriented languages.
Performance aside, I believe the selection is a matter of preference.

RE: Struts - vs XSLT (ASP.NET v. Struts)

[neal]

Actually,

There's nothing to know in XsLT. I mean, the logic is extremely stright
forward basic iterative logic and the tags used to write that logic are the
same as custom tags:

Examples:



And these are just embedded within well-formed HTML and JavaScript so really
... the only limitation I would think is if the person didn't know a little
bit of xpath ... but anyone with any clue of XML knows at least a little bit
of xPath.  :)

I hear ya about the slow XML parsers but they're getting a lot better, very
fast.  The ASP.NET XML parser in particular is suppose to scream.

Well interesting.  Its good to know that others are think along similar
lines and not just me.  Thanks for the thoughts (Jacob too)!

There are a couple of frameworks out there that endorse this idea, and
there's certainly nothing in Struts that mandates the use of JSP.  I think a
person on this list has implemented something exactly as you describe with
Struts.

My .02:

1.  XSLT is slower than JSP, varying upon the complexity of the
transformation.
2.  Anyone working on your presentation layer must understand XSL.  This
eliminates web developers who know HTML/JavaScript and are savvy of custom
tag usage (who *can* work on ASP/JSP pages).


I actually think the idea is aesthetically pleasing, but practically not so
pretty. :)

Joe

Struts - vs XSLT (ASP.NET v. Struts)

[neal]

Alright, so if the purpose of Struts and ASP.NET is:

1. To seperate code from content
2. Make the presentation layer completely declarative

The why not just write a servlet that instead for forward to display JSPs,
looks up a different XSLT for display based upon the action class being
requested ... and instead of having to pass all your data to the
presentation servlet in beans ... you just transform your XML data using
that XSLT.  Seems to achieve the same goals and architecturally removes a
layer if you're going to use XML at all.  (Just servlet and XSL instead of
Servlet, JSP, and XSL).

??

Any thoughts??

If I understand the question properly, we also consider it good practice
to have the control layer set the values before forwarding to the
presentation page. In Struts, the control layer is most often
represented by the Action. We encourage people to always link to an
Action first before forwarding out to a JSP.

Struts uses ActionForm JavaBeans to carry the values that will populate
the JSP form.

I think it would be interesting to boil down what Struts, ASP.NET, and
the other framework do to generic case studies. I put some preliminary
notes here:

Gotcha, looks exactly like Struts way of doing it.

Perhaps I'm a bit daft, but how is this *not* using tags--you just said
"custom tag"??

The mechanism looks damn near identical to me.  I think the pull vs. push
difference is more behind-the-scenes, the actual developer usage looks the
same as Struts.

Oops .. in paragraph 3 (QUESTION) ... the last sentence should actually

Rather, in the ASPX file you would have (a custom tag - aspx:field name="x"

I noticed a few similarities to ASP.NET in Struts (from a 30,000 foot

anyone else thinks of this comparison:

BACKGROUND
In ASP.NET (for those not familiar) there is now seperation of code form
content, similar to thatr achieved in JSP model 2.  They do it via
"CodeBehind".  Effectively, every .ASPX file (new ASP extension) comes can

the same thing as the classes written to facilitate the controller for
various JSPs in an MVC model.

QUESTION

populated in the form.  You wouldn't use tags to grab the data and set it
into the form field.  Rather, in the ASPX file you would have (a custom

Jakarta Commons Lib ... and Struts

[neal]

I am new and still pondering whether to use Struts or not.

I am aware of the MVC pattern as a reason to use Struts but am curious to
know how it's funcitonality libraries and wrappers compare.  Does Struts
provide similar functionality to those libraries found in the Jakarta
commons libs?  Commons offers some pretty sweet stuff.

Does anyone use Commons/Jakarta taglibs along side of Struts .. or does
Struts intend to be a one-stop-shop sort of solution?

RE: Tomcat/Struts - DB Conn Pooling

[neal]

Thanks!

That is a great article on setting up connection pooling directly in Tomcat.

So, I see that some people are using Struts, some PoolMan, and some their
application server (in this case Tomcat) to achieve conn pooling.  I am
curious to know (a) which is the most popular of these three mechanisms? (b)
why?, and (c) which one is generally regarded as the "best-practice"
implementation?

RE: Tomcat/Struts - DB Conn Pooling

So, you find the Struts connection pooling to be a little limited?  What
would you say is the limitation on Struts conn pool?  Is caching the only
significant limitation or are there others?

It sounds like you're saying you prefer Poolman, when possible.  Would you
say your sentiment is pretty typical of most other users out there?

For those of you out there who have written web apps using Tomcat and

Tomcat might also provide this functionality, though I wonder if they

RE: Non-Struts related : input one text field then show description in another field

[neal]

So, you just want to determine the city and state, based upon the user's
input zip code? I think the best thing to do would just break that form up
into steps (first get the zip code, submit the page, and come back with that
data from the servlet).  Sucks to have to do that but if there's that much
data you might not have a choise unless you want to employ some sort of fat
client that can make socket callbacks ... or you could use the iFrame as Joe
suggested.  This would also give you the feeling of doing it dynamically as
the whole page wouldn't have to redraw.

Good luck.

Aah - I see what you're saying.

Well, I don't know if this is for Intranet or internet purposes but either
way I'm presumign you don't want to make the user download a  list of all
possible postal codesthat would be one large page.  :)

How about if you defined a multideminsional array, wherein there are three
deminsions: state, minimum postal code, and maximum postal.  You could then
compare whatever the user enters against the postal code range, per state,
to determine which state is applicable. In which case you would again just
define a method for the onBlur event.  In this case it would be a
user-defined method that would do an integer comparison of the input value,
against the 2nd and 3rd dimensions of the array, in order to the correct
index ... to get you the correct state contained in the first dimension.
>From there of course its just a matter of assigning that value to your

Sounds like you're saying that you want to cause the page to submit on the
onBlur event, correct?

Try something like this:

   


And then course you would do the lookup server-side and return the page
with
the revised list of zipcodes, per the chosen state.  This is a similar sort
of thing to what ASP.NET does with postback.  Note though that onBlur
probably won't work with NN4 and possibly not NN6...last I checked it was
an
event only listened to by MSIE.  Also note that this implies making a lot
of
round trips to the server, which might decrease performance of you app in
high-traffic scenarios.

RE: when to use Struts

Yeah, I know what I am saying would be like reinventing the wheel, and thus
the point of using a framework (to not reinvent the wheel).  However, my
main concern is that learning to use this 'wheel' might take longer than
building one myself.

I'm sure the guys who wrote Struts are masters of the field and I have heard
great things about Struts.  I guess I am simply posting the question to try
to get more information about it.  On the surface it just sounds like one
more thing to learn, and I'm just trying to gauge the value.

What about Struts do you find to be the most valuable features?

RE: perform() called twice

[Neal Kaiser]

This is a little out-there, but, by any chance are you using Netscape 6
and Frontpage for your JSP editor?

I found a bug in Netscape 6 that causes a page to be submitted twice (when
actually pressing it once) if there are certain Frontpage META tags in your
page.

The solution for us was to remove the frontpage meta tags it auto-generates.

One way to tell would be by doing a tail on your access_log file. If you see
two
requests, then that might be the problem.

ActionError Substitution Problem

[Neal Kaiser]

All my substitutions are showing up like this:

Sorry, the username [Ljava.lang.Object;@7268de is already in use.

My code is like this:

String user_username="test";

errors.add("username",
new ActionError("error.user_username.unique",user_username));

I've also tried:

new ActionError("error.user_username.unique",new
String(user_username)));

And my properties file has: 

error.user_username.unique = Sorry, the username {0} is already in use.


I am using Orion and Struts build from 2 nights ago.

What am I doing wrong?

RE: Strange Error with

[Neal Kaiser]

Rather than going custom taglib route, is it possible to use  ?
The problem with that is that the file must inherit from the calling file's
struts
elements.

For example, something like this:





The only include that works is the <%@ include> directive, but that doesn't
solve this
method size limit problem.

Is this a container thing? Or is this a spec thing?

Yep, same here. Increasing the heap didn't do it.  I wish there was a better

Strange Error with

[Neal Kaiser]

I am using Orion 1.4.7. I don't know if this is an Orion bug, or possibly
Struts?  I have a jsp which uses the include directive to read in a list of
countries:


The jsp looks like this:


<%@ include file="../util/countries.jsp" %>



And the countries.jsp is something like this:
..
Tuvalu
U.S. Virgin Islands 
Uganda

If I have 223 lines in my countries.jsp file, it works, no problem. However,
if I go over 223 lines (no matter what line it is) I get this error:

Error parsing JSP page /galacy/register/layout.jsp

Error creating jsp-page instance: java.lang.VerifyError: (class:
__jspPage28_register_regstep2_jsp, method: _jspService signature:
(Ljavax/servlet/http/HttpServletRequest;Ljavax/servlet/http/HttpServletRespo
nse;)V) Illegal target of jump or branch

I just tried putting the select list in the .jsp rather than using an
include -- same error.

I am leaning towards this being a container bug, not a Struts one. But I
just wanted to verify and make sure this wasn't know with Struts first...

Thanks, Neal

RE: Client-side validation (Old questions that die hard)

[Neal Kaiser]

Dave,

One functionality that might be nice for the validation you are working on:

The ability to say that a field is required IF a certain form parameter
exists.

Something like:



 



So, the property "addr" is validated ONLY if the
registrationForm.role="Admin"

That's probably not the best syntax, but I think you get what I mean.

Thanks, Neal

Getting Form Names

[Neal Kaiser]

I am using the struts validation framework
(http://home.earthlink.net/~dwinterfeldt/) but I have a problem because most
of my forms are multiple-page forms.

There is a syntax where you can say if a field is required or not in the
framework.  However, even though a field is required, it might be on the
second page of the form.

So I am wondering if it is possible to get a String array (or something)
from the Struts framework that will list all of the form names (i.e
).  That way I can extend the validation
framework to make sure the field is present before checking if it is
required.

Thanks,

Neal

RE: [Q] TRANSACTION_TOKEN_KEY - Multiple Page Forms

[Neal Kaiser]

Thanks, that makes sense. I'm using that design pattern now. Do you have any
prefered
design patterns for multiple page forms.  For example, if your Registration
example was spanned
over 3 different JSPs, where would you put the logic that knows what page to
validate, and what page to  forward to?  Would you use hidden tags? Would
you use different action paths? (ie saveRegistration.do would be
saveRegistration1.do, saveRegistration2.do, etc)  Just wondering the best
way...

Thanks.

RE: [Q] TRANSACTION_TOKEN_KEY

[Neal Kaiser]

How does this work when they are registering for the first time, not
editing. I can
see that in EditRegistrationAction the token is set... but if they are
registering
for the first time where is the token set? It seems that it would fail when
it hits
the token check in SaveRegistrationAction, but I know it doesn't, so it must
be set
somewhere, right?

JspException: Must specify type attribute if name is specified

[Neal Kaiser]

I just upgraded to last nights build and get the following error:

javax.servlet.jsp.JspException: Must specify type attribute if name is
specified   at org.apache.struts.taglib.html.FormTag.lookup(FormTag.java:669)
at org.apache.struts.taglib.html.FormTag.doStartTag(FormTag.java:441)   at
/getstarted/regstep1.jsp._jspService(/getstarted/regstep1.jsp.java:84) (JSP
page line 47)

This is the line in the .jsp it is complaining about:



And this is what I have in struts-config.xml:

   

and


 

  
  



I do seem to be passing the type, so I'm not sure why I get an error?

Any pointers for places for me to look?

When I upgraded, I updated the struts.jar and copied in the latest .tlds.

Thanks, Neal

Data Validation

[Neal Kaiser]

Has anyone thought about adding data validation tags to the Struts taglibs?

For example, what if we could do:



or something like that.

Could it not generate the necessary javascript, as well as provide an easy
to use
interface for detecting and reporting errors in the Action.perform()?

Just wondering...  Where do people typically do their validation? In the
ActionServlet
or ActionForm? Are there any pros/cons?

Thanks,
Neal

I had to move the struts.jar to orion/lib instead of WEB-INF/lib and move my

RE: Help Debug Form Error? - Can ActionForms be Serialized ?

[Neal Kaiser]

This is a long shot, but one difference between my ActionForm and the
one from the struts example is that my ActionForm implements
java.io.Serializable
(and of course extends ActionForm).  I do this because my Action Form is
eventually
passed to an EJB.  Could that somehow break struts?

RE: Help Debug Form Error?

[Neal Kaiser]

Also, FYI, I updated to last night's struts nightly build and I still have
the
same problem.  For what it's worth, here's the genereated registration.jsp
servlet
snippet that's causing the error:

 // 
start
__tag5.setParent(__tag4);
__tag5.setProperty("addressBook_company");
__tag5.setMaxlength("30");
__tag5.setSize("25");
__tempInt = __tag5.doStartTag();

IT DIES RIGHT HERE in the doStartTag()

My container is Orion 1.4.4.

Thanks,

Neal

Help Debug Form Error?

[Neal Kaiser]

I have a strange problem. I have a simple form that is making use of some


The page stops loading and the following exception is thrown:

I've checked my RegistrationForm.java and it looks OK. There is a get/set
method for AddressBook_company.
Could it be the "_" throwing it off?

Any help is appreciated...

Thanks.

Form errors

[Neal Kaiser]

I probably missed this in the documentation, but if I want to pull out the
error message for a specific field, how would I do it?  Let's say I have a
username which was left blank and I create a new ActionError :

errors.add("username",new ActionError("error.username.required"));

Now, in my .jsp, rather than having all the errors displayed with
, I want to put the
error.username.required error right next to the username field:

  


I don't want it to use errors.header or errors.footer either in this case.

Is that possible?
Thanks.

Reloading Message Resources w/o Restarting Container

[Neal Kaiser]

Is it possible to do this?

Saving HTTP Request Info

[Neal Kaiser]

I'm brand new to struts, so forgive me if this has been covered heavily.

Let's say I am POSTing a bunch of information from a form to an
ActionServlet.  This ActionServlet will
detect I'm not logged in and ask me to log in (by redirecting me to
logon.jsp for example).  Now, after I successfully log in to the Logon
ActionServlet, I want to submit all that POSTed form stuff just as if I was
logged in the first time.

Does struts have a mechanism for this, or should I just write my request
info to my session before logging in and read it in after?

Thanks.

Request for Nightly Build Orion App Server Compatibility

[Neal Kaiser]

Would it be possible to copy struts-config_1_0.dtd  out of the struts.jar
and into the \WEB-INF\classes\ directory so the nightly builds will work
out-of-the-box with Orion Application Server?

Another odd problem which I'm facing is I can't get the example Data Source
Configuration to work on Orion App Server.  I have:



  

I have
  
database
org.apache.struts.example.DatabaseServlet

  debug
  2

1
  

in my web.xml file, but it doesn't look like the DatabaseServlet ever gets
instantiated because I don't see any debug traces at all.

Have any Orion users successfully done this?


Thanks,

Neal

Can't Connect to PostgreSQL with struts-example on Orion App Server

[Neal Kaiser]

Can someone tell me what I'm missing?

In web.xml I have:


database
org.apache.struts.example.DatabaseServlet

  debug
  2

1
  


In struts-config.xml I have:




I know that my postgresql.jar is OK and have tried a connection successfully
with the jdbc URL above.

When I go to localhost/struts-example I get:

ERROR: User database not loaded -- check servlet container logs for error
messages

What's weird is that since I have debug=2 I should see some log() statements
about connecting to PostgreSQL. I get nothing in my log. The only thing I
see on my console is:

New org.apache.struts.util.GenericDataSource
Set org.apache.struts.util.GenericDataSource properties
Call
org.apache.struts.action.ActionServlet.setDataSource(GenericDataSource[activ
eCount=0, autoCommit=false, closed=false, description=Example Data Source
Configuration, driverClass=org.postgresql.Driver, loginTimeout=0,
maxCount=4, minCount=2, password=password, readOnly=false,
url=jdbc:postgresql://localhost/galacy, useCount=0, user=galacy])
Pop org.apache.struts.util.GenericDataSource


Any ideas?

Thanks.

RE: Missing message for key index.title

[Neal Kaiser]

Thanks. I actually have both of those already. I think it might have to do
with
the Orion Server.  I did take the steps that have been posted in the past to
get it to work with Orion, but still no luck.  Could this be related? In my
orion console I see:

[root@www orion]# Orion/1.4.4 initialized
resolveEntity('-//Apache Software Foundation//DTD Struts Configuration
1.0//EN', 'http://jakarta.apache.org/struts/dtds/struts-config_1_0.dtd')

"form-beans" here.

and a bunch more errors.

Missing message for key index.title

[Neal Kaiser]

Can someone tell me what this error means:

javax.servlet.jsp.JspException: Missing message for key index.title at
org.apache.struts.taglib.bean.MessageTag.doStartTag(MessageTag.java:261)

I get it when trying to run the  struts-example on Orion Server.

THanks

Struts and Orion?

[Neal Kaiser]

Sorry if this has been covered before, I just joined (and don't know how to
get to the archives).

Has anyone successfully deployed the struts-examples for version 1.0 with
Orion 1.4.4?
I get the "Missing resources attribute org.apache.struts.action.MESSAGE"
error when
accessing it.

THank you.
