Re: I should know this, but....

[Arron Bates]

First off, no need for the name attribute. If it's not working off the 
same bean structure the other nested tags are, then use the original 
 tag using the name attribute to get to the separate bean.

Otherwise from face value the tag markup looks fine... you may want to 
vary the name of the property to the id for clarity however.


Another point which may save you having issues, is that you can use the 
"property" property like a directory structure with relative and 
absolute references...

Check this out for more informative info...

The "The relative references and the "property" property" part...

http://jakarta.apache.org/struts/api/org/apache/struts/taglib/nested/package-summary.html#doc.PropertyProperty


...with that you can just use the  tag where you need it, 
and use the absolute reference from the root of the bean to get to the 
right spot.

Hope any of this helps in some way.

Re: Nested iterate name

[Arron Bates]

It's ignored as I preferred to have the tags rely on a central source 
the naming of the bean they're all going to be referencing. I feel it's 
safer being represented in a properly set up root tag, rather than any 
one name attribute of a parent tag.

Some people also put the name attributes of child beans from their 
iterate tags etc etc etc, out of habit or something. If supplying the 
name attribute made a tag a root tag, then the property hierarchy would 
be reset, and the form inputs would be broken with incorrect nested 
properties.

I also feel its better readability in the markup to have a root tag 
which is there for that purpose rather than looking through the tags for 
the errant name attribute. Also makes the child tags easier to read by 
disregarding the name attribute.

Anyways, this is all my $0.0.2. If enough people want this changed, then 
it's possible.

err... in the tags, I just get the tag reference and call "getParent()"

Naturally the first child needs the root tag to be the one it finds. For 
the curious, it's all in...
org.apache.struts.taglib.nested.NestedPropertyHelper

All the tags go to the same place to to this part of the deal. Any of 
the nested tags is an example of using it. Most just call...
NestedPropertyHelper.setNestedProperties(this);


Standard XML?... you're giving me a little too much credit there mate.

Re: Nested iterate name

[Arron Bates]

David,

You can wedge a  tag within the form tag. The child tags to 
the root tag will only see the root tag, and those outside the scope of 
the root tag won't know it's there either.

Example...









[... other nesting exploits ...]





...will work just fine. The stuff within the root tag will only be 
working against that bean, and the "other nesting exploits" stuff will 
be working against the form bean. As soon as the tags hit a valid root 
tag, they stop there and use that one. Which is what makes the above 
possible.

Is this the answer you're looking for?...

Re: nested tag issue

[Arron Bates]

Absolutely right.

What this code is trying to say, is that the nested tags need a valid 
"root" tag on each JSP. In this case, David's used the  
tag. It can also be the  or  tags. The form tags 
are bound to their form definition in struts-config.xml, to escape this 
and use an external bean, the  tag is required.

Reason for all this, is the tags look up their parent tag, and it in 
turn looks to its parent etc etc etc. If there's no root tag, then 
they'll run out, and not know what bean they're meant to be working off of.

Even when nesting through dynamic includes, the included JSP's need a 
 tag without parameters, so it's child tags can get that 
reference without running off the top of the JSP page looking for a parent.

Just in case anyone wanted the explanation.

Re: nested:iterate and updating a database

Once the servlet has updated the collection coming in from the form, you 
just fetch it in your action with the getMonkeyTeam() method. There's 
the list, updated and ready to go.

Re: nested:iterate and updating a database

[Arron Bates]

Ken,

More than likely you sould just have the one button for the entire list.

As for only updating the rows that have changed, you'll have to track 
and manage that yourself.
When the incomming data arrives, you'll have to match it against what 
you served, and find out the updated rows that way. If you have to avoid 
session storage, then it will become next to impossible without some 
client side logic. Not a 100% nice, but that's the way it is for everyone.

I think the easiest way is if the rows are substantial enough, to send 
out for updates on an individual basis... ie: edit links on a row, 
click, go to a page to update that row, etc etc etc.

It's a problem that would be nice to solve... need to give it more 
thought, unless anyone else has the elegant solution already made?...

In the JSP or your action?... In your action you can just call the 
setMonkeyTeam() method and pass it your collection.

If you don't want to work over the form bean, you can point a 
 tag at a bean and just use that.

For example, say you have a bean name "theMonkeys" in your session which 
holds your collection, you can simply use the following to iterate...



[...]



But to actually put the collection into the form bean in the JSP itself 
would require a scriptlet. Rather than this, I'd recommend doing it in 
the action, or iterating over the separate bean like above.

Did you try the tutorials on the keyboardmonkey site?...

I'm in the middle of a blurbish page of how to create nested lists etc 
with no logic in the constructors or holding the beans in session.

Hope this gets you a little closer to the target, if not, you know where 
we are :)

Re: logic:iterate and multiple selections

[Arron Bates]

Indexed options in the tag is one way to get it done, but it's not the 
easiest.

Here's a previous post where I put up a quick example of doing without 
nested tags, and with the nested tags...

http://www.mail-archive.com/struts-user%40jakarta.apache.org/msg31991.html

And if you have Struts 1.1b, then you already have the nested tags.


Running example of delete/add functionality using the nested tags...
http://www.keyboardmonkey.com/StrutMonkey/MonkeyStruts_v2.jsp

Primer and tutorials on the tags are here...

For older Struts versions the above site has the jar of just the tags.

Re: No tag?

[Arron Bates]

Because you have to manage the keys yourself, there's no automation to 
it. They're not locked in to using beans and their properties, which is 
what the nested tags are all about.

The nested tags only extend the tags which can benefit from the nested 
context. The errors tag is the same way, and any other tag which doesn't 
work off a bean/property combination.

It could be made so the message tag's property works off the same 
system, but I'm at odds as to its real benefit. What's your case to want 
it?... it may be enough to get me there.

Re: R: Brain Teaser

[Arron Bates]

Daniele's right, but to make things a little clearer than tag semantics...

In web.xml, there's a servlet mapping "url-pattern" attribute which 
tells the servlet to throw things onto the Struts servlet, of which we 
tell it to react a certain way via struts-config.xml.

The action-mapping path in struts-config.xml is used in the form 
attribute, tells the struts servlet as to what action class we're going 
to use to process the request after its finished its input processing 
business.

Otherwise struts servlet wont know what to do with itself and starts to 
use your machines processing power to play chess with Big Blue over your 
internet connection*

It will play chess with whatever's available, even Fujitsu mainframe.

Re: Help on logic:iterate

[Arron Bates]

Think that the answer you're looking for, is that your tags aren't quite 
set up properly. There's work around of a work around. The child tags 
need to work of the bean that is the current object returned from the 
iterate tag, which is why the properties wont work. They also need to 
get the index from the iterate tag.

1) To get the bean from the iterate tag, you need to set an "id" 
attribute, (you did that, but weren't using it. Almost there :)
2) To get the properties working, the child tags need to address this 
bean in the name attribute.
3) To get the indexing, the child tags need to be told they're indexed 
with indexed="true"


For Example...

  





  


...personally, it's a whole lot of mess to have to account for. If 
you're using Struts 1.1b, you already have access to the nested tags, 
which look after each other in a much easier way. No need for special 
beans or indexed="true" properties. Here's the same thing with nested 
tags...

Example...

  





  



...a little easier, because the reference to the current tag is supplied 
by the parent tag. So, the child tags will get the index, mapped 
property, or whatever. And if you're on Struts 1.0/1.0.1 then you can 
get the tags and tutorials and such from http://www.keyboardmonkey.com/next

Anyways, one of these should get you working again.

Re: nested:iterate and indexId problems

[Arron Bates]

Just had a play, and there's a bug in the tag's extra info class around 
the indexId.
Until then, set an "id" attribute also, and it should work.

Seems though the extension is troubled by its super class, and it's 
looking like a fix is required there also. Either way, I'll sort it out 
tonight (few hours from now), so you can download NeXt again tomorrow, 
and it'll be sweet. Actually, from looking at the code, it's a surprise 
that common  tags aren't suffering from the same issue.

Actually, the markup is fine. Specifying name only means that it will 
look for a separate reference too the map outside the bean, which is 
what Siraj is doing here. The  is simply the content which 
the hyperlink is working off.

Something's either URLEncoding the parameter where it shouldn't or the 
request handler is stuffing up the processing of the query string.

Re: Questions regarding Nested Tutorial..

[Arron Bates]

Jeff,

Just a little clarifying... any value object in a list, is a nested object.

1) Not yet, but I only made it today :)
2) Personally, I'd like it to be there. It's the one thing stopping 
nested objects from being created on the fly rather than held in session 
(and that benefits more than nested tag users, eg: yourself). But I'm 
one voice in 10 that can say no to its inclusion in the new version... 
and that's after it's included in the commons project. Just have to let 
the process do it's thing...

You've migrated on, and trying to run a legacy copy of servlet.jar 
somewhere. I get it at work when a rogue version of the jar gets in there.

Update it (or even try removing it temporarily, as JRun should have it's

a little.

As much as you don't agree with Flash, it does have the potential to 
turn the market on its head (if you don't think so, go take a good look 
at the abilities in Flash fx).

That aside, a technology choice of any developer shouldn't bring

that Struts is a powerful enough platform to make the experience all the 
better for developer or user, Flash or otherwise.

Re: Questions regarding Nested Tutorial..

[Arron Bates]

Jeff,

Sorry that I didn't get back to you earlier, but the fact is that I just 
didn't have an elegant answer, besides building blank collections based 
on what you served. Not all that nice, especially when the first bean is 
done so nicely.

The problem is that when the bean is created when the request comes in, 
it only knows to make the first bean. When it tries to get at the nested 
beans & collections, there's none there, and it certainly doesn't know 
how to create them. If you know the structure, you can build the object 
tree in the beans constructor, and it works fine. If you don't know the 
structure, size of lists etc, this then becomes a real hassle. It's fair 
to assume too, that you're not going to know the extent of the data 
coming in, or simply it'd be nice to stay flexible, and just have it all 
happen when the request comes in.

It's not really a Struts/BeanUtils problem, as they're only populating 
what they can get to.

You could make sure that there's an object for every index in your list, 
or key to the map, if you had the "getProperty(int)" style indexed 
property. But the iterate tag can't use it to do it's business of 
showing the collection. To help out, I've made a couple of proxy objects 
that take your original collection, and make sure that the collection is 
expanded properly, and place-holders are used to store potential 
positions. You also provide it the class details of the objects to be 
made in the collections. So when an object is requested at an index, a 
new one will be made to your specs, and then returned to the BeanUtils 
for population.

Works a treat. I've tried it out on my more-than-complex-enough monkey 
examples, moving the scope to request, and it all works great. The only 
thing you have to do, is where you have your collection in your bean, 
wrap it in these collections (there's one for lists, and one for maps), 
and pass it the class definition of your clid beans. Also, because the 
potential is there to have place-holders in the collection (not map, 
list problem only) when it comes in for use by business logic, you have 
to call "clean()" on the list collection, to strip out any place-holders 
that are not required any longer.

I've just posted to the commons project for submission, so it still has 
to go through that process, but I'm putting together some docco whatever 
the outcome to go on my site etc etc. If you want a go at them without 
the extra docco (they have a fair bit of javadoc to them), get them from 
here...

http://www.keyboardmonkey.com/next/ReserveMap.java
http://www.keyboardmonkey.com/next/ReserveList.java

...you'll have to compile them etc.
They're java.util.Map and java.util.List implementations themselves, so 
you can maintain everything by still coding to the interfaces.

They should do what you're after. If not, get back to us...

Re: Displaying a Vector of vectors in JSP using STRUTS

[Arron Bates]

This is all good if you only ever want to show the data. Updating the data is 
another story. There's also the hassle of maintaining the child bean names 
etc etc etc (the last couple of problems you've just had). All managed for 
you.

The nested tags make this really simple (it was the problem they were 
originally created to solve). And they'll help do much more.

For a primer and tutorial...

They're in Struts 1.1b, or you can get a separate jar at the link above.

Re: Struts and X11

[Arron Bates]

This is where I start to run dry. I'm by no means a Unix guru, so this 
particular question should be fired at someone higher on the Unix food 
chain.
But this is all I know...

This is in my Tomcat startup script...

rm /tmp/.X11-unix/X24
/usr/local/bin/vncserver :24
DISPLAY=localhost:24.0;export DISPLAY

...which I am assuming that it's cleaning up stuff first, starting VNC 
(the X client), and a config line for VNC.

I just did a quick lap around the net, and according to this page...
http://www.mail-archive.com/cocoon-users%40xml.apache.org/msg08873.html

...the edit should be in "catalina.sh". But I assume that that is the 
page you just posted. According to them it's all that has to be 
happening. Apparently 'Coon suffers these issues all by itself.

I suppose what I'm tyring to get at is that about these *nix environment 
specifics, I have no idea. But I wish you all the best :)

I do know, however, that buffering the image will have no effect. It's 
the rendering the image to a cnavas that the issue springs up from.

Re: logic:iterate with EJB's, casting problem?

[Arron Bates]

You'll most likely find that the "PortableRemoteObject.narrow()" will be 
the part giving you grief. The tags will have no idea that it has to do 
this. The fact that you can get away with it so easily with a small 
scriptlet will probably mean that it will remain your best option. Your 
problem is very specific and the tags are not designed to handle specifics.

Only other option, is to marshal from this EJB call into a basic bean 
within an Action before you forward to your JSP. Would also make the MVC 
purists happier. :)

What EJB container are you using that's running on top of VisiBroker?...

Re: Struts and X11

[Arron Bates]

It's because the underlying calls to make graphics at some point are run 
out to some native code so that it can run a little more smoother. I ran 
into the same problem trying to get graphics to happen on my servlet 
hosting provider.

Apparently you can get Java 1.4 to run in a headless mode which means 
that it will do everything. Otherwise, the VM needs to get at a running 
X service. My provider solved it by simply running a VNC process under 
my environment.

But, there is said to be more basic solutions like telling 1.4 to be 
headless etc. Do a search on JGuru.com, that's where I found the start 
to my answers. You cn even run a pure java AWT, which also gets around 
the head issues. This does mean you have to change only a few of the 
classes you normally use (BufferedImage etc)...
Pure Java AWT...

There may be others out there.

nothing to do with class size. Java wont use a class larger than 64k.

We also have to give thanks for Mark for passing on good paying customers when 
he's dropped them because he's "always the man"/ignorant.

Re: jsp size limit?

[Arron Bates]

Not really. It's a whopping class, and it's only really become an issue 
with JSP's, because people can throw in so much content, tags etc.

Re: Iterate Tag with Vector of bean

[Arron Bates]

You're probably just suffering from a naming conflict.
The "name" in the iterate tag itself is to reference a bean. The "id" 
will create a bean for each iteration that the child tags can get at. 
I'd first try naming them something different.

Re: variable number of text fields in a form

[Arron Bates]

It appears that it could be because you've nested "through" this property, and 
actually invoking something within your CallHistoryInfoItem returned at the given 
index.

If you're using a nested property (eg: "monkey.bunch[i].banana"), what it will do, is 
call all the getters down the line, and only call the setter on the last bean. For 
example, Struts will call the bean and use the getter method to get at the monkey bean 
(the "monkey" property). Then, it will call the indexed getter to get at the right 
bunch bean (the "bunch[i]" property). From this bunch bean, will call the setter on 
the banana property to set the value. So just keep in mind that the setter is only 
called on the last bean property.

I only say all this as it looks like your CallHistoryInfoItem is a bean in a nested 
structure, and the setter will be called later somewhere in the line.

Hope this gets you out of your problem.

Re: html input elements don't work

[Arron Bates]

You'll need to specify the bean name which is defined in the 
struts-config.xml file for your "createText" action.

Example...


You may also want to put in the ".do" on the end of your action name.

Example...


...just a little thing.

In the immediate, about all you can do is get a hold of the current 
index (or map item in the case of maps) in the form of a scripting 
variable... and yes, to use it means little scriptlets. Nothing's tag based.

Reason for all this is because to cater for everything, in every tag, 
would make the internals quite messy. I'm considering various solutions 
for use in the nested tags (because they're all relative to each other, 
it's not a step outside of their context, which it would be for the 
standard tags), but nothing is substantially clean enough for me to put 
it forward as a standard solution. It all has implications as to how to 
make it available to the values of all the child tags etc etc etc.

Re: Check this out!

[Arron Bates]

Anyone would think that trying to get an opinion on something is an 
uphill battle. :)

Instead of creating an entirely new tag, can you take a look at adapting 
the current one?...
Reason I say this, is that there's already a tag there, and this tag 
will need another name besides "link". "scriptlink" or something. An 
extra tag for people to learn.
Because the logic is already there to do the mapping, and the 
querystring appending etc etc, I think it would be easier to simply add 
an extra parameter called "script" or something that when set to the 
name of a JS function, that when present, will wrap the resulting URL in 
the java script function. This means that *all* current links could turn 
into JavaScript routed links by adding one parameter, and inversely go 
back by removing it. Which I think would be quite sweet.

Otherwise, it may turn out to be just a tag with an esoteric use.

Your thoughts?...

Arron.

Re: More detailed iteration needs?

[Arron Bates]

Have you taken a look at the Struts logic tags?...
...more specifically the  tag. Quite sure this will do 
the job.

As for "displaying first N of the collection", you can set "offset" and 
"length" attributes to the tag, and it will do just that. You can also 
use any form of a Collection, including a primitive Object[]. It will 
retrieve an Iterator from the collection, and go over that. So ArrayList 
will work as well as a Vector (albeit that _little_ bit faster). 
HashMaps and such will also work, but the offset and length will be 
useless. :)

There's a lot of tags in the Struts booty. Take a read over them some 
time. They'll be the answer to most problems.

Re: Iterate Problem

[Arron Bates]

This is all kind of fussy. You have to get the id's and everything 
right, manage the bean names etc, etc, etc.

You can forget all of that stuff and use the nested tags. Makes life 
100% simpler for iterating and everything else.
They've been in Struts since January. Just that not too many people put 
them forward to help the easy stuff, which they make even easier...

Primer, tutorials and downloads...
http://www.keyboardmonkey.com/next

It sounds like a plug, but I've had no complaints from anyone who's 
using them.

Re: Tab Libraries? Bah!

[Arron Bates]

You miss my point. JSP is actually excellent, and very powerful and 
solves everything that it needed to do.
Simpler is not better. There are people out there that only do JSP, and 
are not really into compiled java. Couldn't do that if the power wasn't 
there.

Don't hassle JSP for not being something it wasn't meant to be (a simple 
template engine for designers).

Re: Tab Libraries? Bah!

[Arron Bates]

Do you really think that JSP was made simply to do a templating engine 
to make life easeir for designers and people who only do markup?...
JSP had to fight back at ASP. Something you can hack immediately, no 
compiling and just run it. Really sweet and easy to get anyone going on 
the road to a server side solution. Java lacked that. You had to write 
and compile a servlet to get anything of the sort out of Java. Not 
something that people starting out would want to do. Especially when 
they're probably already written a "HelloWorld" in ASP and on their way. 
Java had to bridge this gap in a complete way, and it did.

In this capacity, and so much more, JSP is quite excellent, and very 
powerful. From power derives complexity however. The effort to a 
templating engine is left to you guys, but JSP is an out-of-the-box 
solution that can suit visual designers (yes you may have lead them a 
little, but they're not all the way stupid. Well...most of them), all 
the way to your coders. There is a need to dumb-down aspects of markup 
(I'm working on another super-simple template engine for other reasons). 
Some need it more than others. Usually the better the designer, the more 
dumbing-down you may have to do (they can be ignorant blighters at 
times), and on the other hand, I started out a designer, and embraced it 
all... anyways.

All this, I feel has to be respected.

It should be fine. To remove my personal doubt, I just tried it out

It even works the other way using  with a .

Re: NESTED TAG PROBLEM .....

[Arron Bates]

The nested tags work off a structure defined within a bean. Not a 
collection itself. So wrap the hashtable in a bean and you're on your way.

You're not using a form obviously, so you'll need the  tag 
to start everything off. Point this to the name you put the bean into 
your session with (currently "hashtable"), and it'll be fine. The nested 
tags work off the premise that they relate to each other. They always 
look up the tag hierarchy until they see a relative tag. Now there has 
to be a tag to start it all, this is what the  bean has to do.

Hopefully, this done it will start working as expected.

If you're still having trouble, there's a primer and a tutorial which 
will walk you through all the steps of using the tags.

Re: nested Tag

[Arron Bates]

If you're after the HashTable ability, you'll require the "bleeding 
edge". The use of a hashtable to get the right nested property was only 
added a couple of weeks ago. So you'll need a recent nightly build to be 
able to do this properly. That could be the problem just there, but 
let's move on...

To calarify... your StandardsForm has a getter method "getMyHashTable", 
which returns the HashTable of QuestionBeans.

Your markup is basically correct, with a few minor insignificant issues. 
You specify the "name" attribute in each instance. This is not needed. 
In fact, the nested tags will ignore what you put, and reference the 
bean specified by the root tag. A root tag is either , 
 (just an extension of the html version), and 
. If you using a form variant, then the name of the bean 
will come from there, if you don't want a form, then use the 
 and point it's name attribue of a bean in scope. ie: your 
StandardsForm bean.
Also, the first letter of a property is lowercase, and the internals 
will look after it.

Resulting markup will be looking like this...







This get anything a little clearer?...

Re: Struts 1.0 and Nested Tags. with Added Classes

[Arron Bates]

If you're using Struts 1.0 you can't just return the ArrayList. Return 
the Object[] by calling myArrayList.ToArray(). The ability to use the 
ArrayList properly in an indexed property was only added to 
PropertyUtils in February some time. You can't just replace the bean 
utils jar either, as for Struts 1.0, PropertyUtils was embedded. I think 
that the "null" error is that it doesn't have a clue as to what to do 
with the List.

Another possible issue, is that you may be confusing your beans. How?... 
In some of the tags you have provided a bean reference via the "name" 
attribute. Providing the name to all but one nested tag (nested:root), 
is a waste of time. Internally, the tags will make up their own idea and 
overwrite whatever you provide anyway. All the nested tags look up to a 
valid nested "root" tag. There are three options. , 
 and . In your case it's  (note: 
 is just an extension of ). So all your tags are 
looking to the form tag to get the bean reference. If that's not 
"theSCBean" it's going to be an issue.

To get it all working off theSCBean, make a  tag inside the 
form tag to take over, and use the theSCBean.
eg...

  

  

  
  

  

  


(I also noted in making the above example that the closing form and 
iterate tags were out of sequence, it may have just been your example, 
as it would have thrown a bad markup kind of error instead of the 
current null problem).

Also note in the above, that I changed the  to 
. Why?...  is there more for the other way 
of using it. Internally, nested tags will "always" set the name 
attribute. Setting the name attribute means that the "collection" method 
of using the options tag wont come into effect. The nested version is 
there for the "name" attribute use of the tag. The collection attributes 
accesses another bean all together, so it's best handled by the original 
tag. You've correctly made the bean via the define tag (good stuff :), 
and all you have to do is use the original tag and you'll be golden. If 
you move up to Struts 1.1, there's a nice "optionsCollection" tag there 
which is excellent for nesting, and doesn't need that extra bean define 
step.

The only other difference with the example above, is that I moved the 
 to be around the select tag. Only personal taste, as I 
like to keep the select and the accompanying options tag in their own 
unit as they both together form the input item. Makes it a little easier 
to read.

Anyways, I hope that somewhere in all that you find the rest of your 
legs in using the . I'd rather err on the side of too much 
info, than not enough. :)

Arron.

PS: Taken the nested tags tutorials on www.keyboardmonkey.com ?
   It will walk you through making lists within lists and whatever 
else. All the way up to making a tree.

Re: [Q] nested:nest and nested:write

[Arron Bates]

Instead of  try  with the nested property...



If that returns the error, it's all in the setup of the bean etc.
Because it's a "no getter method" error, I'd be checking over the 
methods and their signatures, making sure they're all public etc. It's 
quite a specific error. It's found the bean, but it can't get into it 
for one reason or another. If all your methods are public, start putting 
in System.outs (or logging calls) for the initial Beans' "getAccount()" 
method to make sure it's called, and then into the child bean etc etc to 
make sure all the methods are in fact being called.

Re: [Q] nested:nest and nested:write

[Arron Bates]

Nothing is outwardly obvious... but it won't be in the nested tags as 
it's forming the property correctly ("account.account_no").

One way to test, is to use the normal bean:write tag using your named 
FormBean and the full nested property.
eg:


And if you've named the bean the same name you have in the Struts config 
(as this is the name that the nested tags will be working off of), you 
should get the same error. With that said, it will have to be the scope 
of the bean, or the naming of the properties, the visibility of the 
methods etc etc. Nothing nested tag specific. All I can say is that the 
nested tags are laid up fine, and will be working off the bean named in 
the struts-config.xml

Trees & JSP Recursion in Struts 1.1...

[Arron Bates]

The ability to draw trees in a flexible, efficient and ultimately 
expandible manner is really hard. But Struts, JSP's and the Nested Tags 
in Struts1.1beta can do it easily and in a very elegant fashion... (or 
with Struts1.0/1.0.1 with a nested tags distrib younger than a month)



I just finished uploading a tutorial to my site to show you all how to 
do, in easy steps, everyone can do it.
And it's fun!
The end of the tutorial, you'll end up with a page which will display 
some of the file system of your JSP server!


Anyways, it's all there, some have been complaining that there is no 
"control" or "tag" to make trees... well, instead of having to rely on 
any one piece of code, the framework itself is capable of pulling it off 
in a very ellegant and most powerful fashion (you do your own markup, no 
putting up with what any one control does or doesn't do!).

Just give it a try.

Go to...
http://www.keyboardmonkey.com/

...and click on the "[NeXt]" section if you want a little ramp-up on the 
nested tags first, or just go straight to the "Pilot Light" section for 
the tutorials. You could go straight to the tutorials if you're quite 
familiar with Struts. They should get you through.

If you don't have Struts1.1, just pick up the nested tags distrib from 
the "downloads" section.

Enjoy.

Arron.

Re: nested tags question

[Arron Bates]

The nested tags as of probably a month and a half ago, the nested tags
penetrate dynamic includes.
I tried to mail the few (but vocal :) people that were throwing things
at me to get it done, you may have been the one that got away. Apologies.

Putting up a tutorial on my site tonight to show the potential of true
recursion and JSP's to make a tree structure. Trees have never been more
fun. :)

Re: Iterate update

[Arron Bates]

Martin confirmed it for you. But here's the spiel you're after...

The items in an interate tag need to have their properties set via an 
indexed property. The String[] you mention there is a valid form. Any 
Object[] is fine. In all truth, the setter for Object[] is academic. The 
PropertyUtils will actually call the getter for the array, and then set 
the item in the array for the index that it has. The actual method 
"setMyProperty(Object[])" will never get called.

As of a couple of months ago, you can now use any implementation of 
java.util.List in the place of the Object[].

As a side note... have you thought of spending the few minutes it would 
take to change your methods to the Object[] style and find out for 
yourself rather than get impatient with the people of the list (and now 
the developers list)?...

Then it wouldn't matter what we said, you'd know, regardless.

Re: indexed - Nested property and Javascript

[Arron Bates]

The following is how it would go...

document.MyForm.elements["echeancier.date[0]"]

...you use whatever ends up in your input's name attribute. index or 
not, mapped or otherwise. If you want to iterate through them, you could 
use...

document.MyForm.elements["echeancier.date["+ i +"]"]

Sorry about the lack of the tag. It's on its way.

Re: Cannot find message resources under key org.apache.struts .action.MESSAGE

[Arron Bates]

It should have been all you required.
I had the problem developing the other night, and that was the problem 
there.

You might want to try downloading the nightly build and trying again. As 
these types of bugs are being rectified it may pay to make sure that 
you're running on the latest.

add key="org.apache.struts.action.MESSAGE" to the  tag.

eg:


Try that one.
Some other bright spark found it (didn't leave his name). It's a problem 
with 1.1beta. Still has yet to be fixed for the full 1.1 release.

Re: iteration tag

[Arron Bates]

The name of the bean associated with your form, or any other bean name 
which is in scope.

For your example, add a bean to the session under the name 
"announcement" and you're golden.

Re: usage of html:options

[Arron Bates]

The tag Ted mentions is html:optionsCollection, and it's in Struts 1.1

If you have to run 1.0/1.0.1, then what you're doing with the 
bean:define is the standard use. Or, if you have a collection for the 
values, and a value for the labels, then you can just use the 
html:options, with the "property" property pointing at the bean property 
that will yield the value list, and the "labelProperty" pointing at the 
bean property that will be the list of labels. Only thing about this is, 
is that they're separate lists.

But to use the list of beans that themselves hold the label and values, 
then there is no other way but your bean:define usage you already have, 
or the new html:optionsCollection tag.

Re: nested tags

  The nested version of the bean:message tag wasn't added until the

library for the older struts 1.0/1.0.1 from...

Re: problem with arraylist and iterate

[Arron Bates]

There's a jar of the tags on the site for your older Struts. Many people 
are using it, and it works great.
It's up to the latest code which is in the Struts CVS version, so you're 
not missing out on anything.

Other than that, you'll have to slog it out with iterate tag and setting 
the indexed property on the child tags. Which is tougher.

Re: nonexistent "nested:message" & get properties in Action code

[Arron Bates]

No, no reason. It was simply missed.

I've made it, but a need a little more time to test it out. There 
shouldn't be any issues, it's a simple extension.
Do you want to test it also?... I can mail the implementation to you 
when it's done instead of waiting for the Struts build process to tick over.

Re: problem with arraylist and iterate

[Arron Bates]

What has to happen is the properties for each of the inputs in the list, 
have to get the correct "indexed" property to update correctly every 
time. The nested taglib in the current 1.1beta Struts can help you do 
this with ease.

If want a tutorial to walk you through it, or you're running an older 
version of Struts and need teh nested taglib library, go here...
http://www.keyboardmonkey.com/struts

After that, you shouldn't have iterating problems again.

Re: Tiles, included pages, and taglibs

[Arron Bates]

They may be separate pages in terms of development, but at runtime 
they'll become separate servlets all together and will be parsed as 
such. Being separate servlet entities, they'll need the talib 
declarations etc etc.

If you do static includes, the server will simply pick up the include 
file and write it into the same servlet. In this case you don't use the 
taglib declarations.

Re: Javascript problem referencing nested form fields

[Arron Bates]

This one is scheduled for a tips page someplace. I'm adding it to my 
site, but Struts home page should have one... anyways, onto the real 
topic

As you already know, the dot notation is getting in the way and messing 
up JavaScript document object model.

For the field you want, use...

document.forms[0]["address.number"]

...so to alert it's value...

document.forms[0]["address.number"].value

...to pull focus...

document.forms[0]["address.number"].focus()

You get the idea. All it needs is a string. So the following is the same 
and makes things handy...

var myVar = "addrss.number"
document.forms[0][myVar]

And naturally you can access and field in this way to make your scripts 
run on a standard.

Implications: none. it's cross browser. So go play :)

Re: OptionsTag bug using nested property?

[Arron Bates]

Your work-around is that much of a work-around, as it was the only 
solution up until a couple of weeks ago.

If you're running 1.1beta or something near it, you'll have the 
optionsCollection tag. It's a more natural fit to the system. Use the 
name attribute, to select the bean, the property attribute to get to the 
collection, label attribute which is the bean property of the item in 
the collection that is the label, and the value attribue the bean 
property of the item in the collection that is the value. If you're 
running this struts you could use...


 


And the nested version, naturally works against the same bean as all the 
other tags, the property attribute relative to the others etc etc etc.
But your workaround is the standard solution for most people.

Re: Multi Indexed & Nested properties samples?

[Arron Bates]

1.
Nope. Only that ArrayList will be slightly faster at runtime because 
there's no synchronization for threads on the class (and doesn't need to 
be, as there's only one bean to a user). Vector will work fine though. 
Most likely not a noticeable speed difference.

2.
Yes, they are nested beans. And no, they don't need to extend anything 
special.

3.
That part is up to you. As for the indexed tags, they're not in the 
1.0.2 distribution. So you could only get them if you updated your 
release to 1.1beta. If you get that, then you have the nested tags also. 
I'm probably bias but I find the nested tags easier to use for 
iterations and have a wider range of ability beyond that. If you want to 
keep running the older Struts (1.0.2), then you can pick up a library to 
use them from my site which has the ability of the nested tags in the 
current Struts distrib...
http://www.keyboardmonkey.com/struts

There's also a tutorial and primer on how to use the tags, including the 
creation of lists in the way that you're after.

Or, use a stylesheet! :)

That's a good one actually. Problem is though, you'll never see what's 
cut off by the width in IE. NS6 actually shows the whole thing when it 
drops down. Quite cool NS!.

Re: Controlling MaxWidth for html:options or html:select?

[Arron Bates]

I'm afraid that there's nothing you can do about it.

Limitation defined by Html, because no horizontal scroll bar will appear 
so users can read the whole string. You'll either have to split it up 
into the different parts or abreviate it in some way.

Re: Multi Indexed & Nested properties samples?

[Arron Bates]

Annie,

Somehow you're using a tag library that doesn't have the indexed tag 
ability. The error is complaining that you've specified the 
indexed="true" attribute, but it doesn't know about it one way or another.

When you speak of two vecotrs, is one return from a bean in the other?...
Anyways, This stuff is easier with the nested tags. Learn about them 
here...
http://www.keyboardmonkey.com/struts

And yes, you can have whatever you want editable on your list. The 
nested tags intro and tutorial on the site above should show you 
everything you'd need to know about editing things in lists, nested 
lists or whatever. There's a primer and tutorial to get you going.

Re: Difference between 'id' and 'name'

[Arron Bates]

"name" is the bean that you're working against (with the property 
attribute etc), and "id" is the bean that's going to be the result.

You could just the bean properties from the returned object.
Say each one had a "name" attribute, to write it out...






Nested tags version...




Either one will do what you're after.

Re: Property file

[Arron Bates]

Take a look in your Javadoc for standard edition, and look up 
java.util.Properties

Easient way to get a file from your classpath is to use the class 
object's getResourceAsStream method.
eg:
Properties p = new Properties();
p.load(this.getClass().getResourceAsStream(configFileName));

Then you just use the properties.
If you get stuck, there's a ton of this stuff in the forums of the 
JavaSoft site.

Re: nested:options not retrieving values

[Arron Bates]

Because you've specified the "collection" attribute, it's trying to find 
a bean reference under that name specified. Because it has to be a 
reference to a collection itself, it can't be changed to a nested property.

So, expose a bean to the name using the nested:define, in the collection 
attribute, and you should get that bean reference to use the original 
 tag.
Example...








The simplified nested version, is when you just use the property 
attribute to get a list if objects, that will render their string form. 
Not all that handy when you want to specify the different label and value.

The best solution is in the nightly builds or 1.1 Beta. Use the new 
 tag that extends the new 
 tag. This is pretty much what you're wanting 
actually. Set the property attribute to the bean property that is a 
collection of beans (that you have), and then set the label and value 
attributes to point to the various bean properties.

So, just replace your  line with...



Either one of these above will get things happening.

Re: check box

[Arron Bates]

Sanjay,

It should work for any Html input element. As long as you know the 
resulting input name, you can get at it.
...fun part, is that you can do string concats too if you want to be 
more dynamic...

Indexed example:
document.forms[0]["something["+ i + "].somethingElse"]

Re: check box - Attn. Ted Husted, Craig

[Arron Bates]

Sanjay,

1) The name of the form is the "name" attribute of your action details 
specified in your struts-config.xml file. It  also has to be the 
reference name of your bean. So...

document.myBean.submit()

...would submit the form.

2) For this I just have to recommend a great JavaScript reference. The 
JavaScript Bible by Danny Goodman.
But to kick you off...

Great way to reference events from your form items, checkbox for example...


...and in your java script to handle this...

function doSomething(inElement) {
  if (inElement.checked) {
alert("hello");
  }
}

And one more free extra tip...  :)
If you're trying to reference an element that has dot notation (nested 
properties), you can do so like this...

document.forms[0]["myProperty.nestedProperty.something"]

... to disable the above example element ...

document.forms[0]["myProperty.nestedProperty.something"].disabled = true;


For more detail and everything else, Danny Goodman has the answer :)

Arron.

Re: JavaScript problem

[Arron Bates]

If you give the submit tag a property value it will change the name to 
that of the property. It should match a bean property, but it can be a 
fake one.

eg:
public void setMyNonSubmitTitledProperty(String temp) {}

...and in the markup





...it should render...

Re: Displaying recursively defined bean...

[Arron Bates]

The biggest benefit this has which the other tags cannot capitalize on, 
is that they can be used in a markup manner without too much regard as 
to how much code is in the JSP that started the run. The included JSP 
could be the fifth inclusion, 100 beans down, but as long as the 
definition of the current bean matches the tags it uses, it will work. 
And work for everything, form inputs or whatever.

The other tags and the explicit dot notation fashion, is limited to your 
knowledge of the entire data model and have to explicitly set it each time.

With further deliberation on its implementation (and a couple more 
people beating me for the feature), the nested taglibs are now using the 
session object and the tag objects themselves, to temporarily store the 
information needed to get dynamic includes working.
In short... you can use dynamic includes with nested tags!

So this is a retraction of sorts. :)

It's a retraction because the result, is indeed very cool. Now being 
able to have true object style recursion in the markup to draw a tree 
that can have all the form inputs you can eat. Oh, it is a beautiful 
sight :)

I already have a working tree in an app from this system. I'm working on 
a tutorial at the moment to show it off and define the details. But for 
a brief going over... here was my test.

For the first page...

  

  

  

... and the included JSP ...

  
  Test: 
  

Only detail being that the included page has to be started off with an 
empty  tag (because all the child tags need a parent to get 
their details from). Simple enough.

You can get the jar update from my site, or the Struts nightly build.

Re: Nested Tags - new be

[Arron Bates]

Sanjay,

I'm all for some client-side operation, but at some point the server has 
to find out about it so that it knows how to manage your data model 
properly. Forget the nesting tags, this problem will get you in whatever 
your server side solution is. Once the Html is served, the server just 
doesn't care until it gets the next request.

The nested tags just evaluate the model at JSP execution time, just like 
any other tag, JSP or top-down servlet.

If you had to do it without a trip to the server, you will have to 
gather all the details of the extra rows in some hidden form element, 
and then process the details on the server when the user finally submits 
the page. It's possible, but not fun. Not the least of which is the 
client-side rendering of the page. If you're using IE5+ NS6+ you can 
just do Html replacements easy enough. The ability is certainly there... 
but approach with caution. It could quite easily become a nightmare.

For example, if a user is adding a whole heap of rows, they think that 
the data is in there because it's on the screen as they typed it, and 
simply types in another URL... all the data is lost, never to return. 
Not even with the back button (because JavaScript objects and state are 
not cached by the browser). Unless you can be certain that the page will 
be posted to the server after filling out these new rows, I would steer 
clear of it all together.

Another option is to have a page on a hidden frame send updates to the 
server. Every time that something changes to the data on the screen, get 
JavaScript to fire off the hidden frame with the update. Because you're 
only wanting to send updates, there's no heavy Html having to be 
generated by the server to be returned, maybe just a yes or no to tell 
your JavaScript whether the server got any errors etc.

Whatever you do... it will change the way you have to code your web 
interface, and increase your development time. How familiar are you with 
JavaScript?... This aint no simple mouse-over. :)


The monkey example uses the server-side management simply because a lot 
of puritans out there simply refuse to regard anything with client-side 
logic. And it's also 100% easier to do and manage.

Re: nested:iterate - set method not called

[Arron Bates]

The setter on a nested property, such as the list properties in my 
example, is only there as a convenience. The Struts managing code will 
never actually use it. It only worries about the last bean in the nested 
property definition. My construtors use it to make the simple example 
easier to do.

As for storing a reference to the form bean in all the shild beans... 
no. This is probably not model behaviour. I only did it so I could get 
my delete buttons working for the banana objects. The setter of the 
banana's object knows that the bean is to be deleted as it's been 
called. The reference to the parent bean is there so it can call the 
parent bean and tell it that it wants to be deleted.

If you don't need this more advanced bean driven functionality, then you 
really should avoid it.

Re: Cannot submit the form using button

[Arron Bates]

Because Struts doesn't just write out what you put in as the action. It
looks up what you specify in your struts-config.xml file, and relates
that back to something that the server and Struts really needs.

If you really needed to do this (it would be better to have a
dispatching style action), look at what the action is in the form tag of
the resulting html and change that accordingly.

Re: Nested Iterates...

[Arron Bates]

Marcelo,

Excellent! You're only one step away from taking over the world... :)

For properties that aren't collections, use the  tag 
instead of the the  tag. It represents logical steps in 
the nested hierarchy, that aren't collections.

For example, say for every monkey that works at the plantation, they 
each have an adress, but all address information is in another address 
bean. The markup would look like thus...


  



  


...there's a list of monkeys, but only one address for each monkey.
Your instance is the otherway, but same theory. One nested bean that 
will lead to a collection.

What does confuse me a little is that the beanRefName on the start of 
the nested property. The name of the bean itself should not be there, 
only the properties of the things that you're trying to manipulate under it.

I'm assuming that the bean you want to get at is returned by a getter 
method inside your Struts bean?...

If it is, just change that tag and you should be on your way.

Arron.

I'd say it's time for a new provider.

Provider I'm using for my java hosting has private VM for only $20 
canadian per month, and you can frisbee up to the site whatever you

Re: Nested Iterates...

[Arron Bates]

Marcelo,

It's kind of fuzzy as to where you're trying to get to. There's three 
loops. So I have to assume that you want a radio button for each 
"answer" within each "test" within each "item". Say there's three 
elements in each, you'll end up with 27 radio buttons. Right so far?...

This is going off the list of items, then list of tests, then list of 
answers. With this, you should be striving for the following underlying 
property...

item[i].test[j].answers[k].radioIem

The markup should be something like this...











Just to clear a few things up. The use of the nested root is to serve as 
the basis of a nested tag structure for a JSP. It takes the place of a 
 or  as not all pages will be specified by a 
form. The tag then takes the name attribute as the name of the bean that 
the tags will then reference. You've placed it half way down the 
structure, and the danger of what will happen here is that the tags will 
assume that this is the start of a hierarchy, and start again. That's 
why the name attributes of your resulting Html doesn't have the "items" 
reference. So move the root to the start, or if there's already a form 
tag there, remove it all together.

Second... there's no real need to specify "name" attributes in the 
nested tags, as your input here will be ignored anyway :) This is 
because all the tags will be looking to their parents to get the bean 
name, as it's assumed that they're working together. The only thime that 
the name will make a difference is in the initial rooting tag.

The same almost goes for id's. Id's will define scripting variables for 
you, and nothing else. They're not a "requirement" for the nested tags 
to do their thing. To get the tags running, all you'll need are the 
"property" attributes that define the property of whatever the current 
tag is addressing.

As for your duplicate indexes... it's the first time I've come across 
it. :) ...so there's nothing that I can directly say to combat it. 
Hopefully, it will be taken care of with the above tips taken care of.

If you want to get a little more familiar with the tags from the ground 
up, there's a primer and a tutorial on my site which should take you 
through everything...

Re: How do you do a map with hotspots in Struts

[Arron Bates]

Html image map is basically links. Work the same way, sending GET 
requests only.

Only way to submit a form without JavaScript is to use the image tag. 
Then you cn do the form thing.
When clicked, it will pass the x & y coordinates. You can figure it out 
on the server. Much harder than links from the image map.

But no, Strut's doesn't have image map shape tags.

Re: Development approach question

[Arron Bates]

If known for nothing else, I may go down for creating the infamous 
Monkey/Banana bean model example :)

I don't think that one object per row is much of an overhead for the 
benefit it brings. You are going to have to marshal your results anyway, 
so you may as well create separate objects. Hell, you could even have 
the beans as a proxy only and go driect through to the result set. But 
that's not very MVC.

The nested tags don't "imply" anything. They simply make easier work of 
some more complex markup. Even with nested beans you can use the old 
tags. The nested tags are also better at adaptation. If your spec 
changes, then it will be easier to update with the nested system. Even 
if I'm not nesting beans, I still use the nested tags. They simply make 
life easier.

You could take me as being bias :) ... so are there any other opinions 
out there?...

Re: html:options bug?

[Arron Bates]

The collection attribute needs the bean reference only. The dot notation 
is for your property. Because the collection isn't the bean itself 
you'll have to use a define tag or something to make a bean reference 
directly to your collection, then use that reference in your collection 
attribute.

For your second example... The collection attribute is overriding, and 
ignores the name attribute. It's meant to be the direct link to a bean 
reference that itself is a collection.

Re: Problem using the nested taglib

[Arron Bates]

Almost. :)

 is a valid nested tags root. For compatibility reasons. 
 is literally an extension of that. Other than that you can 
use the  for non-form based stuff.

Indexed attribute is not needed. It has limited use in all the tags, and 
doesn't penetrate (multiple iterators) very well. The nested tags will 
ask each tag to get the underlying property. When it comes across the 
iterate tag, it will get it's correct index. All behind the scenes 
without you having to worry about it. It will work correctly for all 
tags, not just some, which the indexed attribute fails to do. For all 
intents and purposes, you only need the "property" property in the 
nested tags because all the rest is done for you. Makes management of 
markup much easier.

Re: Server-side Charting libs?

[Arron Bates]

Java 1.2 should be all you'd need for a good charting package. Not that 
I have a particular library in mind. I have seen one on sourceforge 
someplace. They are out there.

When ever I've needed a chart I've luckily had to the time to piss 
around and make it myself. Java2D in 1.2 should be all anyone needs to 
get the job done. Has the ability for some very sexy imagery.

You can use any charting package, as long as it will render to an Image 
object or some sort (Buffered or otherwise) which you can just pump from 
a Struts action using Sun's own JPEG output stream, which you can get a 
hold of in thier Advanced Imaging Toolkit or something (www.javasoft.com 
:) . With that you set the quality etc. As far as I know all the JPEG 
stuff etc is now in 1.4

Re: nested:iterate - set method not called

[Arron Bates]

The getter will only ever be called, as it's the middle-man.
The system only wants to set the "name" property on the nested bean. It 
will call the getter of the "extrainfo" object to get at the nested 
bean, and then set its property. Never actually calling the setter of 
the parent bean property.

Re: how to edit an array of records with action forms?

[Arron Bates]

Nightly build version can use implementations of the java.util.List 
rather than having to get back the primitive array object. Makes things 
easier to work with.

Returning the Object[] actually renders everything but ArrayList style 
collections useless because the mapped collections and such don't know 
how to update from an index. Returning the array from an ArrayList 
itself isn't that big a hit, as it's backed by such an array anyways.

Re: how to edit an array of records with action forms?

[Arron Bates]

Who's fixing the number of records?... The tags will happily do whatever 
with what they're given. The monkey example adds and deletes objects in 
the various lists with ease.

You could even map the bean properties to access columns in a result 
set. Wouldn't be on the "best practice" list however :)

Re: nesting tags cannot find EmptyTag

[Arron Bates]

You're running an older version of Struts I take it (1.0, 1.01)?...

There's a jar made especially for these versions of Struts that doesn't 
have the extra tags like the empty tag.
Download "nested_tags_10.jar" (binaries), "nested_tags-src_10.jar" 
(source) from...
http://www.keyboardmonkey.com/struts

That should get it working. You will also have to replace the tld with 
that which comes in the jars, otherwise weblogic will still complain 
(All this is because weblogic parses and checks the tld's). The location 
and name of the tld's don't matter, as long as it matches the definition 
in your web.xml and JSP's etc.

Hopefully that will get you working.

Arron.
