RE: Is there a better way to write this code?

If you want logic and valid xml docs, have a look at xsp (implemented in
Cocoon et al.)

Re: Is there a better way to write this code?

[c tang]

One simple reason for not using scriptlet is that
making a jsp page an invalid xml doc.

Yeah, right.  Write all the assembler you want dude, and you will be
relegated to the heap of the unemployed.  The day belongs to the VM, whether
it be MS or Sun.

So why complain about not being able to do something and just do it in a

Re: Is there a better way to write this code?

[João Guilherme Del Valle]

The thread is going, so let me in. :)

Keith is right. It´s a practical tool, not a taglib translation of Java
Language, not a wrapper to it. My honest opinion is that it´s possible (and
very easy) to make this kind of tag available, but it´s not the point. The
idea behind taglibs is to encapsulate logic, presentation, business or even
persistence logic. But providing method access would bring shortcuts to some
tasks that shouldn´t be there, the JSP should be kept as simple as possible.
One could say "It´s there, but if you don´t want to use it, just do not!".
Why doesn´t java lang allow explicit pointers? Why is type safety so
disciplinefull(!)? Why we (java developers) don´t want the "unsafe"
directive from C# (this kinda disables some consistence checks, like null
pointer exceptions)?

After proving Struts beans with access to method any methods, we could
agregate operators, classses and maybe even tag reflection. Just for fun,
not personal. ;-)

João.

Re: Is there a better way to write this code?

[Fernando Esteban Barril Otero]

In my opinion, one should use JSP with taglibs to 
present the data. If you need special
processing or more complex behavior, you
should encapsulate it inside a bean or a
custom tag.

The examples you mentioned (Integer.toOctalString(),
String.toLowerCase()) can be easily achieved using
the JSTL. If you want other, you should create a
tag for it.

Re: Is there a better way to write this code?

I like struts as a 'practical' tool for business development.
I haven't had a problem with it being restrictive in (fairly limited) practice. I hope 
that struts
guides you towards best practise & standard techniques.
On wrappers - I normally wrap collections anyway to apply restrictions & to add extra 
functions.
(A very old design pattern). That's my 2 cents worth.

Re: Is there a better way to write this code?

[c tang]

I think you miss my point.  We are lucky that the
examples I gave have some special tag builded in
struts.  How about writing Integer.MAX_VALUE,
Integer.toOctalString(), String.toLowerCase() etc.
There are tons of public API in jdk not mention third
party one.

You are right this thing is very powerful.  But that
should not be the reason to not doing it.  I can
always do the MyBean.wait() in scriptlet.  There is
nothing to stop that.

Re: Is there a better way to write this code?

[Arron]

I can see what you're trying to say and it would be truly flexible if 
you could do that.

But I can already foresee the reaction from the die-hards, and that is 
that it would give the person doing the markup "too" much power. 
Probably get at some things that shouldn't be gotten at, like MyBean.wait().

Nice idea, wouldn't get past the committing committee I'm afraid.

And the fact is, if you want to get that sort of power, you may as well 
script it. There's plenty of ways to get a hold of your object for 
scripting. The MVC model is to decouple a the model. Having access to a 
specific api isn't decoupling.

Re: Is there a better way to write this code?

[Fernando Esteban Barril Otero]

To write the size of collection object or array,
you can 
and write with .

The "size" bean can also be used with the tag

...


In the case of toString, if you don't specify a property
attribute in the tag , the output is the toString
of the object, like the above example.

This may help to avoid scriptlet in the JSP in some
cases.

Creating a wrapper class may get rid of scriptlet in
JSP. But that means for every public api (such as
Collection.size(), Object.toString()) that does not
fit get/set pattern, a wrapper class has to be created
in order to avoid scriptlet using struts.  IMHO, that
is worse than just using scriptlet because it bloats
the class number significantly.

You have three options on starting the nested tags.

nested:form - extends html:form
html:form - naturally
nested:root - this is the "formless" option for starting off. It requires
only a "name" attribute which has to match the name of a bean which is in
"scope". This can be done by defining a bean in the struts-config.xml and
have it put in session scope, or you can use the  tag and set
the name of the nested:root tag to the name of the bean in this jap:useBean
tag.

One other thing...




...there's no need to set the "name" property here. It will be ignored by
the nested tags anyway, as they must rely on the founded name set by the
parent tags.

RE: Is there a better way to write this code?

[Alex Paransky]

Some background:

I am using Struts 1.0.1.  The nested tags were obtained from
http://www.keyboardmonkey.com/struts.  I could not find a reference manual
for the nested tags, but looking at the .TDL it appears as they were
intended to be a 1-to-1 mapping with struts.  So I simply replaced



In the examples on the www.keyboardmonkey.com/struts site, all the tags were
used inside of a form.  I don't have a form, perhaps that's why I was
getting a null pointer exception.  I am new with STRUTS so I do not know why
this is happening and I have not had a chance to dig into the source code
yet.

For one, I recommend getting your properties into getter/setter
methodology. Simply so you can use the wealth that is the Struts tagging
system (as it's (the bean spec Struts runs against for it's model
components) kind of what it's all about).

By "'raw' String" do you mean the object's "toString()" method?... Any
property that yields and object to be written out will have it's
"toString()" method called to write it to the output.

I'm also curious about your "null pointer" issue with the nested

Re: Is there a better way to write this code?

[c tang]

I agree with Alex that current strut taglib has a big
deficiency.  It allows only access through get/set
methods of a property.  How do I write the size of
collection object to a page without resorting
scriptlet or <%=?  How do I write toString() output to
a page without resorting scriptlet or <%=?

I had a proposal to allow x.y expression to get y
in the this order:
(1) x.getY()
(2) x.y()
(3) x.y

In this way, to write toString of x object to a page,
simply use


This proposal is shotdown.  Without this, scriptlet
has to be used in jsp.

Re: Is there a better way to write this code?

[Arron Bates]

For one, I recommend getting your properties into getter/setter 
methodology. Simply so you can use the wealth that is the Struts tagging 
system (as it's (the bean spec Struts runs against for it's model 
components) kind of what it's all about).

By "'raw' String" do you mean the object's "toString()" method?... Any 
property that yields and object to be written out will have it's 
"toString()" method called to write it to the output.

I'm also curious about your "null pointer" issue with the nested 
extension (for some reason :).
Can I get a hold of the bean and JSP you were trying to run it with?...
