Re: how to solve a problem of fetchin' HUGE collection into form

[Elizabeth Barham]

A method that I used for a user to find out his or her employee id was
by having a 'search for employee id' link on a page next to a text
field where the user is to enter his or her employee id since most
employees don't know it.

This caused a new window to display, allowing the user to enter in his
or her name. They enter their name, hit submit, and in the same new
window, the results were displayed. When the user selects one of
these, the javascript populates the main browser window (the one that
launched the search page) and the new window closes itself.

In the above app, if the search resulted in only one record, then that
record was used to populate the main browser window, otherwise it
displayed all the results (which probably wasn't very wise in
retrospect).

Perhaps if the results are, say, over 25 records, then you could ask
them to be more specific or perhaps make pages for them to select from
- such as when you use a search engine on the web and receive a great
deal of results - 25 each page or whatnot (and perhaps with a text
field to re-do their search since at that point they'd realize that
their search wasn't specific enough).

An extension to the above method is by using javascript to initiate
the first query on the pop-up window, too. If there is only one result
then javascript populates the calling window (such as when a user is
pretty sure that the street name is correct but wants the system to do
a quick check; perhaps feedback could be provided in the status bar).

hth, Elizabeth

Re: problem

[Phil Steitz]

Look at your servlet engine log (servlet.log if you are using Tomcat with
the default setup).  Most likely the ActionServlet associated with your web
app is not loading because the data source initialization is failing.  The
mappings aren't there because the initialization failed.  The error message
will (hopefully) tell you why.  Make sure that you have the Oracle JDBC
driver jar in your application's WEB-INF/lib.

Sorry - this solution method doesn't seem to work in any way.

It seems that you have to use scriptlets again. Like in point 1.1 of the

It is not struts-, but MVC- specific, with a lot of Informations for using

You want to put 300k records in a select box!?
You havent really thought very hard about this have you?
I wouldnt worry about the app freezing for a long time. Its nothing compared
to the several days it will take your poor users to scroll through the
select box trying to select the street

rofl

Your best bet is to replace the select box with a popup window that has
somewhat more advanced methods for the user to find and select the street
name and then write the value back to the form field using javascript.

Re: Newbie pls help: Anyone using JBoss 3 w/ Struts 1.1?

[Tadashi Ishikawa]

Hi Brian,

I've tried the URL http://localhost:8080/bad/saveRegistration.do
I saw input form normaly. Your ActionForm was created, wasn't it?
When I clicked 'Save', I saw blank-page, but no exception.

As I suggested at last post, JBoss already found *Your* ActionForm 
before WebClassLoader find it.
Remove Struts-related classes from your-ejb.jar file, then it will work.

Hope this helps.

Problem with checkbox

[Sudhir]

Hi,

In my form I have got a list of organizations and I need to update only checked 
(selected by the user) organizations to database.
In my bean I wrote getter and setter methods to the list of organizations.

My problem here is while getting the list of selected organizations (while editing) I 
need to make the selected organizations
checked.  while populating I am populating the list of selected organizations to the 
form. If I try to put an attribute called
checked to checkbox tag it is giving error(Attribute checked has no value). And if it 
put some value like checked="true" it is
giving the error(Unable to find setter method for attribute: checked). Even though 
they are not getting selecting.(while editing the
form)  So how can I make the selected organizations checked.

Can anybody help me in fixing the problem.

Thanks and Best Regards,

Re: how to solve a problem of fetchin' HUGE collection into form

[Arron Bates]

Dare I say it... better info design. The most I've had was 500. From the
user's point of view, this is not good.

The freezing will most likely not be the server side, but your browser
slowly rolling over and having a cardiac arrest.  :)

Take the lower end of 100,000 options. If eack option had only one
letter, one byte, the dowload is already 1MB. Take that to an average of
say 15 bytes per record up to 300,000 and the result is one impressive
drop-down box.

Try getting the text that would be rendered into Html, get it into flat
Html, and then test it on the browser. I'm quite sure that you'll be
changing your mind and making it a free-text field real quick.

It sounds like you need to replace your drop down box with a link to a
search screen.  On the search screen, the user types in a few letters and
the system displays just the streets that start with those letters.  Then
the user picks one and goes back to the form.

RE: Weblogic 5.1 + commons.logging - HERE'S THE ANSWER!

[Ren Bitonio]

Dean,

I believe you are talking about Struts version 1.1Beta1.  If so, then that
version of commons-logging.jar has a classloader problem issue, that does
not work smoothly with Weblogic 5.1.  I had this problem earlier with WLS61
SP2 and later resolved it.

You need to swap out your commons-logging.jar.  I believe the 5/9 nightly
build was the first edition to resolve this problem, as I checked its source
code to see if LogFactory class was fixed, regarding which classloader to
use and load the factory implementation.  It worked!  The latest ones should
work as well.

By the way, other than getting a newer jar file, there is another
workaround, which is placing the original jar file in the Weblogic's
globalclasspath, yet this is not the preferred route.  

Give it a try, and let me know how it works out.

Good luck,
Ren

I placed the commons-logging.jar into the WEB-INF/lib directory, however, it

I just recently upgraded to WebLogic6.1sp2 and Struts1.1 (build of 6/18).  I
thought I had done everything correctly to upgrade my web app to Struts 1.1,
but I was getting various NotSerializableExceptions.  So then I just tried
running some of the example web apps and I got the same problems, which
leads me to believe I didn't configure something right in WebLogic.  From
reading the mailing lists, there seems to be some sort of systemic problem
with getting NotSerializableExceptions under WebLogic, but I couldn't relate
any of the info IO saw to my specific problem.  Do the stack traces below
that I got running the struts-validator example mean anything to anybody?  
Thanks in advance,
Vic

Re: Use Jakarta's ObjectRelationalBridge (OJB) for your Struts app's persistence layer

[Steve Muench]

Here's an article illustrating how to use the Oracle BC4J framework
to quickly implement your collections of value objects for MVC-based
apps without hand-coding.

http://otn.oracle.com/products/jdev/howtos/bc4j/bc4j-collections.html

I'm working next on a writeup specific to building BC4J+Struts
applications.

Have fun.

RE: Weblogic 5.1 + commons.logging

[Chen, Dean (Zhun)]

I'm using sp8 I believe. But it's on Unix.  The jar files are in
/WEB-INF/lib directory.  I don't understand where WebLogic
looks for Jar files. Does it look in the WEB-INF/lib directory, what about
the appclasses directory?

Thanks,

Dean Chen

Re: 1.1b1 xml

[Dennis Muhlestein]

I got the 1.1b1 files.
I'm sure I'm using the correct ones because DynaActionForm works.

This could be another quirk with my system.  I've certainly had a few
during the upgrade process.  Maybe someone else can verify this.

To see the errors, I turned the debug level in my tomcat/conf/server.xml
of the ROOT context to 3 (or higher).

Re: 1.1b1 xml

[James Holmes]

Which version of Struts are you using?  Only Struts
1.1b1 and the nightly builds will accept the 1.1
config files.

You have to use a 1.0 config file for any other
versions.

1.1b1 xml

[Dennis Muhlestein]

I turned debugging up in tomcat just for the heck of it.  (ROOT Context
debug="3")  Tomcat printed a whole bunch of xml errors when I reload my
app.  The app worked correctly anyway (Go figure)

My xml validator validates my 1.1 xml ok.  If if change the dtd to point
to the 1.0 version instead and try to validate the xml, I get the same
errors that tomcat printed.

Basically, I think that no matter what dtd you specify, Struts is using
the 1.0 dtd.

I had this in my struts-config.xml:

http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd";>

RE: Use Jakarta's ObjectRelationalBridge (OJB) for your Struts app'spersistence layer

[Schneider, Eric]

Just one more to throw out there.  Solid design.  Has a good modeling tool
to create or reverse engineer a relational database.  Plus it generates java
source.

http://objectstyle.org/cayenne/ 

I just started using it a week or so ago.  Extremely happy so far.  Requires
the J2SE 1.4 tho...that may be a problem for some.

RE: Validator problem (or user problem... not sure which yet)

[David Winterfeldt]

The change from using multiple set-property elements
was made right after beta since it wasn't very clear
to call setPathname muliple times.  The Validator is
run through the ActionForm's validate method and
returns a standard ActionErrors object.  The
additional tags that used to come with the Validator
were for features now incorporated into Struts.

html:messages - Iterate through messages/errors.

logic:messagesPresent - check for the presence of a
message/error (can pass in an optional property to
check if there is a message/error for an individual
field)

logic:messagesNotPresent - check for the absence of a
message/error

Re: html:errors tag funny null strings

[Tim T. Young]

Are you using Websphere?  If you are, when null String objects get written
to a jsp
they produce a "null".  Early versions of Websphere did not do this but we
had problems
starting with version 3.5.3.

I just put a errors.header= and errors.footer= in the properties file and
it takes care of it,
since I didn't have anything I wanted to display like in the example below.

Actualy I'm not missing the entry for the error, since it gets writen to
the page, but there are aditional "null" strings.

I have this in properties file:

text.login.password.error=Password is required

on the jsp page I have



but the output on the page is not just: "Password is required"
but : "null Password is required null".

Does that make sense ?

RE: tag for the blank string to " " ... performance

[Niall Pemberton]

Alternatively, you could sub-class the struts PresentTag and override the
doStartTag() method to output the   if the condition is not true (I
haven't tested it, but see below example).

Then use in the same way as the struts PresentTag ... how clear is that?

  
  
  


===
import javax.servlet.jsp.JspException;
import org.apache.struts.util.ResponseUtils;
public class PresentTagNbsp extends
org.apache.struts.taglib.logic.PresentTag {

/**
 * Perform the test required for this particular tag, and either
evaluate
 * or output a " "
 *
 * @exception JspException if a JSP exception occurs
 */
public int doStartTag() throws JspException {

// Present, output body
if (condition())
return (EVAL_BODY_INCLUDE);

// Not Present, output  .
ResponseUtils.write(pageContext, " ");

return (SKIP_BODY);

}
}

RE: Dynamic Forms

[James Mitchell]

I'm interested to know how you are dynamically persisting these fields?
Certainly not in a RDBMS.  Perhaps this can be resolved with better design.

It almost sounds like someone is shoving this design at you and expecting
you to code it this way.  Is this the case?  If not, there are better ways
to structure your application so you don't have to do such a hack job on the
front-end.

It's not just about Jakarta...  from just a passing experience with 
the two tools, I found the mapping syntax for OJB to be far, far more 
comprehensible than that of Castor JDO.  Plus, have you ever looked 
at the source code for Castor stuff?  yikes.

I had heard somewhere that the Castor project was in hibernation, or 
worse... is there any truth to that?  So far i've still had better 
luck with Castor than Jakarta Commons Betwixt for Bean<->XML Binding, 
but I like Betwixt's approach better, and figure it's only a matter 
of time until the tricks to get Betwixt working sink through my 
skull...

I'm glad to see this become part of jakarta. It seems that of the three 
  things most needed by struts users(connection pooling, Object 
Relational Mapping and Caching) there are jakarta projects for all. I 
would like to see these formally brought into Struts. Of course they 
should be replaceable, but I find it odd that there's things in the docs 
like this: "Struts generic connection pool is an optional component. 
Many Struts applications use other connection pools for better 
performance, especially with high-volume production systems."

It seems that with Fulcrum and OJB we should be able to have it all in 
one simple download and tutorial.I know a lot of this is in Expresso but 
I'd like to have it all under one license and tutorial. I haven't tried 
Expresso but it looks like it replaces several Struts pieces rather than 
just addding functionality.

Re: tag

The forward tag allows you to give a name to view
component that can be referenced by Actions.

Take a look at the config file DTD for more info on
the config file's elements:

http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd

I also recommend reviewing the User Guide for details
on how the MVC architecture works with Struts.

The Struts Console make's managing the config file a

Maybe that's all I really need.  I also tend to lean towards Jakarta

I can understand this, that's why I didn't start out with Expresso.

I don't know if I'm in the minority here but I came from a graphics -> 
html -> javascript -> perl/php/asp -> jsp direction and am learning to 
properly separate everything by learning struts. I tend to think of 
Struts as entire web development system rather than just the frontend. I 
also have a lot of Jakarta "brand loyalty" because it helps with the 
whole decision making process and jakarta projects have good mailing lists.

the actual error message. Ex.: "null Password is required null".

What's going on ? Is this fix-able ?

RE: Validator problem (or user problem... not sure which yet)

[wbchmura]

the problem I was having was caused by the struts-config.xml file 
defining the plug in like:





I took a look at the struts blank war and copied that syntax over which 
is like this:






And it started recognizing my rules.  Now I cannot get it to show error 
messages, although it does successfully redirect back until the 
validation requirements are met.  Does validator feed the error messages 
into the normal html:errors?  I noticed it had a validator taglib at one 
point, but I am not sure where it is now that 1.1b incorporated alot

Where I have this in my validator.xml file...

?1 This means it should give me an error if it is not filled in?
?2 Should I have to invoke something from the action to check it, or is 
it just like an actionform?
?3 What else can I try?  Its like its all working, just ignoring my

Lot's of stuff in your action class, but I see that you defined a
DynaValidatorForm in your  but you are casting it as a
DynaActionForm in your action class...if you cast it correctly as a
DynaValidatorForm and then invoke the validate() method (like in my
previous email), it might correct the problem...try it...

Re: Why Tiles?

[Ted Husted]

The next closest thing might be SiteMesh,
http://uk.opensymphony.com/sitemesh/

Or, you could compare it against the Template taglib, but that may be
too similar to draw any real constrst. 

The real comparison, I think, might be between using Tiles and not using
Tiles.

Re: Use Jakarta's ObjectRelationalBridge (OJB) for your Struts app'spersistence layer

[Ted Husted]

I don't see any reason for Struts to adopt any particular approach to
representing the model. There are already a number of packages for this,
including Castor, Turbine, ObjectRealtionalBridge, and like a dozen
others. It's cool that one of these will sport an Apache License now,
but Struts developers should be able to choose their own model layer. 

Of course, if anyone wants to document some good ways to use Struts with
any of these packages, I'm sure that we'd be happy to expand the User
Guide in that direction. But I think Struts' position as an independant
controller for Java Web applications fills a very real need. Other
products have tried the all-in-one approach, and it's just too much for
a lot of people to swallow. A layered application should be able to
choose for itself what component it wants to use on a layer-by-layer
basis. 

There were several issues with the GenericDataSource class in Struts
1.0, which didn't seem like they were ever going to be resolved. To give
people fair warning, I put some disclaimers in the documentation. Since
we're not selling anything here, there's no reason not to tell the
unvarnished truth =:0)

Moving forward, we're moving the dependencies to the Commons DBCP and
can concentrate the development efforts there. I've already noticed that
the pool in Struts 1.1 is more robust than 1.0.

Though, personally, I think the odd thing is that Struts supports
connection pooling at all. Bit too close to the model for my taste. But
at the time it was added, there were few datasource-based connection
pools available. 

Down the road, I think the Stuts DataSources feature may become a way to
manage and swap between different datasource connection pools, rather
than to just load an internal implementation. This can be a useful
feature for a controller. You might want to run unit tests against
different pools, side by side, or switch to another pool for
troubleshooting, which seem like useful controller features to me.

Weblogic 5.1 + commons.logging

[Chen, Dean (Zhun)]

Hi,

I'm migrating my Tomcat application to WebLogic 5.1, in doing so I am
getting this error:

Thu Jun 20 15:05:07 EDT 2002:  Error

I placed the commons-logging.jar into the WEB-INF/lib directory, however, it
still complains. Has anyone seen these types of error before? Is this a
weblogic problem or a commons-logging problem?

id?

[Kamholz, Keith (corp-staff) USX]

When you use the  tag, do you have to define the id that
stores the result of the iteration before the tag?
My code is:

  

  
  
  
  
  
  

  
  
NO ENTRIES
  

If I don't define the id before the iterate tag, I get a runtime error that
says:
Cannot find bean mc.oldDept in scope null:
However, if I do define the id, then I get a compile time error that
complains about a duplicate variable.
Maybe the "cannot find bean" error is referring to the "oldDept" part rather
than the "mc", but I dont' know.
What's going on?

RE: Validator for Struts 1.02

The 7/2/2001 release is the Struts Validator 1.0
release to go with the Struts 1.0 release.  I even
have a 1.0 download which is just the 7/2/2001 release
zip renamed.  The 7/2/2001 release is very stable.  A
lot of people were using it with no bug reports for a
long time.  And even subsequent work done on it for
months was very minor until I started making the
Validator work with the Struts nightly builds.

I'm glad to see this become part of jakarta. It seems that of the three 
  things most needed by struts users(connection pooling, Object 
Relational Mapping and Caching) there are jakarta projects for all. I 
would like to see these formally brought into Struts. Of course they 
should be replaceable, but I find it odd that there's things in the docs 
like this: "Struts generic connection pool is an optional component. 
Many Struts applications use other connection pools for better 
performance, especially with high-volume production systems."

It seems that with Fulcrum and OJB we should be able to have it all in 
one simple download and tutorial.I know a lot of this is in Expresso but 
I'd like to have it all under one license and tutorial. I haven't tried 
Expresso but it looks like it replaces several Struts pieces rather than 
just addding functionality.

Re: Struts Validator and global commands

[David Winterfeldt]

If you are referring to redefining forms between
locales, you only need to override change from the
default locale (no language or country defined).  So
if the default locale has first name, last name, and
phone number and you wanted a different phone number
mask for french.  You would just have to create the
form with the same name and duplicate the phone number
field with the different mask.  

If you want to actually create shared groups of fields
for something like an adddress, you can't currently
create fields in the global section.  I want to do
that though.  So it will be something that eventually
gets done.  Then you could create a field set for
something like an address and reuse it.  But right
now, you will need to duplicate similar fields between
different form elements.

Correction - Using SwitchAction to switch to default sub-app

[Mete Kural]

Sorry I have to make a correction. 

I said in my email:

I meant to write this URL instead:
http://localhost/switch.do?page=/&prefix=

Thanks,

RE: html:base tag and tiles?

Byrne>>  I had a similar issue with the template layout being a sub

Subject: html:base tag and tiles?

I'm using tiles for my primary page definition, and I've chosen to put
my common tiles building blocks into a "web space" subdirectory
called "tiles", including my main layout tile.  When I try to use the
html:base tag to define the default URLs for my web pages, it refers,
naturally enough to the tiles subdirectory since that's where the main
tile lives.

What I'm looking for is a way to get the  element that's emitted
to refer to the top of the web space, i.e. http://localhost:8080/app/
and not http://localhost:8080/app/tiles. 

Of course, I could put the mainLayout.jsp in the top directory, but I
had really wanted to factor the basic tiles definitions into their own
directory

Has anyone run into and solved this problem?

Using SwitchAction to switch to default sub-app

[Mete Kural]

Hello,

I've been trying to get a hold on how to effectively
use these sub-apps but I'm confused about how to
switch between sub-apps still after reading the few
messages on the topic already in the archives.

I have two sub-apps in my web-app: default and
/catalog.

I added the switch action to my action-mappings in the
/catalog sub-app config file i.e.
struts-config-catalog.xml



If I call the /switch action in the /catalog sub-app
it should switch to the default sub-app if the correct
parameters are given.

But when I type this in the address bar of the web
browser:

http://localhost/catalog/switch.do?prefix=&page=/

, I get the directory listing for /catalog the first
line starting with "Directory Listing For /catalog/"
and then listing all the jsp files in my /catalog
directory.

Shouldn't it take me to the index page for the default
sup-app, i.e. /index.html ?

I set up the switch action in the default sub-app's
config file as well. When I type this in the address
bar of the browser:
http://localhost/index.html?page=/&prefix=
It takes me to the index page for the default sub-app
as it should. But why not when I call the switch
action from the /catalog sub-app?

Are my parameters incorrect? I'm giving a zero-length
string prefix for the default sub-app and the URI "/"
for the index page. What do you think I'm doing wrong
here? 

Peace,
Mete

RE: FW: Bean Usage - Collections

Thanks!  I'll try it out.  I decided not to use bean:define either because

Keith,

I don't use bean:define, but it works in most cases. Instead, I 
create the bean in my action class. That means you will have to 
specify the .do or /do/... url whenever you have a link to your page. 
The Action will run before you ever hit your JSP so you create the 
bean in the Action and use the request passed into your Action 
to set the action in the proper scope. You do not have to define the 
bean in struts config.

The values entered on the form will be placed in the bean specified 
on the html:form tag. If that is a struts form, you will end up with 
two copies of your bean (it can be convenient because then you 
have from and to values), one on the form and one associated 
with your action class. The name you specify on your html:text(?) 
tag would be the name you assign to the attribute you saved 
in the action class.

Hi everyone,
I'm new to struts and right now I'm working on some collections in my

I have an EntryHolder bean class that has 3 properties (ArrayLists of
entries) which each hold a different type of entry.  Each type of entry
is
it's own class.  I then have a form that fills in the info into the

class.
I believe I can just use the  tag (before the link to my form

bean
in struts-config, if the input doesn't come from a form?)
In order to the put the entry into the corresponding ArrayList, do I

to the list in my Action that handles the form?
If so, how do I access that bean in the action?  My only guess is that
I get
it from the "request" parameter, or the HttpSession .
Any input would be greatly appreciated.  Thanks!

RE: Dynamic Forms

[David Morris]

Adrian,

Would it work to store your property name/values pairs 
in an arrayList and then use iterate or the nested tags 
to loop through the values when you display them? The 
generated text tag would then be something like 
property="dynValues[0].value" value="Some Value". You 
would build the arrayList of dynProps each one having a 
value, name pair.

  

  

  

David Morris

>>> [EMAIL PROTECTED] 06/20/02 08:14AM >>>
Hi,

I have checked through almost the entire archive and encountered loads
of articles covering dynamic forms, but all use the DynaActionForm,
which requres the properties to specified in the struts-config.xml
file.

In most cases this is fine but for a few JSP's the property names are
being dynamically generated at run-time so I can't add them to the
struts-config file.

Struts Validator and global commands

[Alok Ghosh]

Hi, I am using the new version of Struts Validator (v1.1) to validate a
form on one page.

 

The top of my form has common fields, ie. firstName, lastName, and the
bottom of my form is dependent on a drop down box.  (ie, different forms
are shown on different drop down selections. Like Province if Canada is
picked, or State if USA is picked)

 

In my validation.xml file, I know I can have multiple versions of the
same form in different  tags.  Ie)   
and .

 

But is there anyway I can specify a set of global  for the top
common part of the form?

 

I know under  there is a  category used for
variables, can I place  tags there?

 

How would I go on about doing something like this?

Please help,

 

Thank you,

Alok.

If u've i18ned  ur bean:messages wut's the problem.
place appropriate "error.something.like.this" accordingly in all of ur

and use this name when creatin' errors i.e for example

ActionErrors errors = new ActionErrors();

if (sometrouble)
 errors.add("ErrorName", new

Re: Struts-Tiles Questions

[Cedric Dumoulin]

  Tiles is shipped with Struts1.1 in the contrib folder.
  Documentation is in struts-tiles.jar, in the same way struts documentation is in 
struts-documention.
  Versions on Jakarta and on original Tiles site are exactly the same. Binaries from 
original site contains more war files (like blanks*.war). They are not generated in 
the Struts distribution to not overload it. It is just an option in the ant build file.

  The overhead in using Tiles is to compare to the gain in maintenance and reuse. It 
is a comparison in the same order that choosing between using C or Java language ;-). 
But the Tiles time overhead is not in the same magnitude.

Change the line in ApplicationResources.properties to instead read:

That is, you should have braces ('{' and '}') around the ints instead of
