Re: Embed picture in HTML email
Would hopefully be the same for the Mailer taglib. It's cool that Mozilla supports the cid stuff, maybe it's even some kind of published standard out there, and things like Notes and Groupwise might support it too [must think who I can mail to test *grin*].

Anyway, you'll see lots of special tags that exist. I've never really played with them though. I'd definitely be interested in seeing any info which details the pseudo-library of extra tags that Outlook converses in, but have never really gone looking for them. Maybe it's possible to write a Java library for creating Outlook-HTML pages and then sending it as a mime-type that only Outlook responds to (?). We could then send 3 versions of every mail, plain-text, html and outlook-html. Just some thoughts...

JSTL Function Library
I am using Tomcat 5.X. I'm not sure which version of JSTL I have, but here is my jsp reference: %@ taglib prefix=c uri=http://java.sun.com/jstl/core; % I wanted to trim a variable I get from a database. I've searched the Sun website and have found the function library. %@ taglib prefix=fn uri=http://java.sun.com/jsp/jstl/functions; % I'm having trouble using this. Here is the tag: fn:trim(row.user_id)/ Here is the error: No tag trim(row.user_id) defined in tag library imported with prefix fn I'm not sure if it is a version thing or what. Do I need to make a tld file for this? I can't find this library on the Jakarta web site. Should I just use Jakarta's String library?
Re: JSTL Function Library

%@ taglib prefix=c uri=http://java.sun.com/jsp/jstl/core; %

There's really nothing you need to do to the server*, just make sure it supports

to make sure you've got the latest version: 5.0.19). As for your app, all you
should need to do is download Standard-1.1 and place jstl.jar and standard.jar

RE: Embed picture in HTML email
Its pretty simple from the docs included with mailer taglib but, heres how
it works with some examples :
First page is a simple html:form that collects the data. The
javascript:validate() method on that page forwards on to another html page
(the page that goes in to the body of your html email) which has these
tags in :
--
%@ taglib prefix=c uri=http://java.sun.com/jstl/core; %
%@ taglib uri=http://jakarta.apache.org/taglibs/mailer-1.1;
prefix=mail %
mail:mail

mail:setrecipient type=toc:out value=${recipient} escapeXml=false
//mail:setrecipient

mail:message type=html
html
body h1 go go gadget legs /h1
/body
/html
/mail:message
mail:send/
/mail:mail
c:redirect url=nextPage.do /

The user only sees the form page and nextPage.do and recieves a nice big
'go go gadget legs' in their email.

RE: Embed picture in HTML email
I used the mailer tag lib to generate the email sent from this page :

click the button 'e-mail this item to a friend' on the middle right of the

receive the mail.
It sends html including css and images etc. The trick is to generate a
normal html page and then send the built page as the body part of the

You can't embed pictures in emails. You can have img src=foo etc in
them, but the picture will be obtained from a server of some kind.
Some mail clients [okay, Outlook is the only one I know of] allow for some
proprietary xml-ish tags to be in your emails which will load resources
from attachments.
I usually send from Outlook to Pine to see this, but I'm sure there are
ways to see what the html really looks like in Outlook. Save it or
something. Anyway, you'll see lots of special tags that exist. I've never
really played with them though.
I'd definitely be interested in seeing any info which details the
pseudo-library of extra tags that Outlook converses in, but have never
really gone looking for them. Maybe it's possible to write a Java library
for creating Outlook-HTML pages and then sending it as a mime-type that
only Outlook responds to (?). We could then send 3 versions of every mail,
plain-text, html and outlook-html.
Just some thoughts...

RE: Beans static method in non static way
Hi Bill,
Thanks again for your reply. This JavaBeans component model specification
seems quite hard to locate.
I did find a PDF from 1997 on the Sun site (ver 1.01). Is this the only
point of reference? Can you provide me with any recent JavaBeans Spec
documentation?
I suppose I am struggling to find the meaning/advantages of excluding access
to static methods (accessed in a non static way).
My knowledge is limited with AWT, reflection, intraspection etc, but I'm
guessing that using these while doing GUI development (other than web) would
allow/enable access to these types of methods.
Cheers,

Subject:RE: Beans static method in non static way
Thanks for the clarification, Andrew. JSTL is predicated on the
JavaBeans
component model and is such getter methods are expected to be
instance
variables. And I certainly understand your limitations as far as
the code.
I think in a lot of cases, a getMaxLength() method would be an
instance
method that uses a static field.
However, since you indicated that you cannot change these things --
if you
are using a JSP 2.0 container like Tomcat 5 than you could use JSPs

Subject: RE: Beans static method in non static way
Thanks v.much for your reply. To the contrary, I don't have a lot of
static
methods, but many objects each with one or two static methods.
For example: we have a class called 'Subject' (yep nothing special -
building HTML forms here). Classes like Subject are provided to me
in a
package.
Subject has static getMaxLength(). If this was accessible in JSTL it
will
make my life as the web guy a lot simpler.
Instead I have to create a class like SubjectHolder which has a
Subject
property and a method which calls this.subject.getMaxLength().
(This is starting to sound like Struts Form Beans etc... but I have
found
them limiting and for now choose to avoid them) Then JSTL also
starts to
look like ${thing.subjectHolder.subject.maxLength}.
If Subject class has a max length, any instance also has a max
length. I
don't see how this suggests state? Can you elaborate?
I can't really dictate the way these classes are designed. Wrappers
it may
have to be (in the order of 10's to 100's!).
Cheers,
AS

Well, I don't mean to sound like a OO-snob, but I have to
say that
if you
have a lot of static methods than it means that your code is
written
more
like a procedural language than an object-oriented one.
That being said, if you have to de4al with thte static
methods than
the best
way I would think is to use the wrappers like you are doing.
I
mean, the
method you access with JSTL are object properties --
properties mean
state
-- so, static methods mean no state -- since I think it is
completely
reasonable to not be able to access static methods -- aside
from the
technical/implementation reasons.
Another approach is to turn your classes with the static
methods
into
singletons and change the static methods to instance methods
on the
singleton.
That is all I can say for now as I need to get back to
watching my

Subject: Beans static method in non static way
Hello,
I have read most of the discussion on JSTL1.0/1.1.
Especially concerning static
RE: Beans static method in non static way
My 2 cents:
Although static methods are valid code applied to instances of
the class; this is a matter of parsing and code generation.
Static methods are logically methods of that instance's
class object.
In either case Java's reflecton mechanism doesn't seem to
provide API access to invoking a static method. Though
I don't recall having tried such...

Hi Bill,
Thanks again for your reply. This JavaBeans component model specification
seems quite hard to locate.
I did find a PDF from 1997 on the Sun site (ver 1.01). Is this the only
point of reference? Can you provide me with any recent JavaBeans Spec
documentation?
I suppose I am struggling to find the meaning/advantages of excluding access
to static methods (accessed in a non static way).
My knowledge is limited with AWT, reflection, intraspection etc, but I'm
guessing that using these while doing GUI development (other than web) would
allow/enable access to these types of methods.
Cheers,

Subject:RE: Beans static method in non static way
Thanks for the clarification, Andrew. JSTL is predicated on the
JavaBeans
component model and is such getter methods are expected to be
instance
variables. And I certainly understand your limitations as far as
the code.
I think in a lot of cases, a getMaxLength() method would be an
instance
method that uses a static field.
However, since you indicated that you cannot change these things --
if you
are using a JSP 2.0 container like Tomcat 5 than you could use JSPs

week ending on date
What mechanisms in JSTL (or even the datetime taglibs) are there to
perform date calculations? So far i've only seen formatting options.
Essentially i'm looking to calculate the Friday (or Saturday) date for
the current week (and eventually be able to generate a list of dates
representing week ending...).
I'm using the following to obtain today's date.
jsp:useBean id=now class=java.util.Date /
and formatting it using
fmt:formatDate value=${now} pattern=MM/dd//
Thanks.
Anuj.
