RE: PDF File Display in JSP-Struts
The question that Abhijeet asked was how to do it in a JSP. I agree that
doing this is a kludge.

Why would you ever do this? This looks like a complete and total kludge.
If you are sending back binary data (application/pdf), just do it from the
action class using the response.getOutputStream() and return null from the
execute method.
Advantages:
- you already have everything you need right there
- you eliminate the entry in struts-config
- you eliminate a useless jsp
- you can specify any content type (not just one per jsp)
- you get better exception handling
- the list could go on and on...

It may be an issue with using white space inside your jsp. I normally do
something like this (using a custom fo to pdf bean)... (note: everything up
to, and including, the c:set var=junkWhiteSpace is on one line)
%@ page contentType=application/pdf %%@ taglib prefix=c
uri=http://java.sun.com/jstl/core; %c:import var=blahFo
url=/test/blah.fo /c:set var=junkWhiteSpace
jsp:useBean id=foToPdf scope=page class=com...FoToPdf /
c:set target=${foToPdf} property=inputFo value=${blahFo} /
/c:setc:out value=${foToPdf.pdf} escapeXml=false /

RE: Struts custom tags tutorial
Using some style sheet logic in conjunction with JSTL is an elegant
solution. Here's a quick snip of code to do just that (the arraylist should
come from the action, and the style sheet should be in it's own file, but
you get the idea).
*snip*
style type=text/css
!--
.negative_true {
color: #ff;
}
.negative_false {
color: #00;
}
--
/style
%
String dataValues[] = {500, -200, 100, 20, 5, -7, 0, 800};
pageContext.setAttribute(dataValues, dataValues);
%
table cellpadding=4 cellspacing=0 border=1
tr
tdstrongValues/strong/td
/tr
c:forEach var=dataValue items=${dataValues}
tr
%--
This next line is really the only logic that needs included for
negative value checking.
My personal opinion is that this code has a small footprint, and I
wouldn't mind having
this presentation logic duplicated in multiple places throughout
my app.
--%
td class=negative_c:out value=${dataValue 0} /c:out
value=${dataValue} //td
/tr
/c:forEach
/table
/*snip*
Have fun.

Jarrod Lugo

In the case, the user described below, I didn't.
What he wanted to do was, based on data values, guarantee a color scheme and
other criteria, i.e. maybe all negative numbers should be in red. This is
view based logic, but one of the priciples we all use is try not to write
the same code twice.
I might be missing something but, JSTL, and most view technologies (except
custom tags, source includes and tiles), don't have the ability to
modularize common code or have strange syntax to achieve the modularization.
So to say just use the standard technologies and let the view have the view
logic is a bit of a cop out.
I suspect that most of what he wants to do is already in struts-layout so
there is a work around without writing his own tags.

I am not sure if you agreed with me or not on that one. In
case you did not, to clarify: I think that the view should
handle all the logic for presenting the data. It should not
be tied into the business logic For example, the business
logic should know how to get all the parts from the database
that are active. The View logic should cover how to make
them into rows, colors, highlighting.
The display should really only know what data is coming back.
From then on it should have the responsibility of making it
pretty and paginating and such.
I think we may be on the same page

Logic in the display which needs to know anything about the
specifics of business logic, makes no sense to me, although
there seem to be very few of us who have this attitude.
Examples of this include field size; required fields;
number logic (internationalization), etc.

Here are two easy ways out...
http://edhill.its.uiowa.edu/display-examples/
(Wonderful, worked great for me)
or
http://jakarta.apache.org/velocity
(Simple templating, integrates nicely)
my code corresponding to these struts tags else where. This
way the logic to display the data will not be there on the
JSP page.
Why don't you want the display logic there? I always
considered that the view should control how the data is
displayed... I could (and often are wrong about these
things) but it strikes me as strange. If you are trying to
keep it simple for HTML developers, try velocity. Most
anyone can do templates in that.

Hi Steve,
Let me clarify:
I know some of the basic concepts of struts and I have
been using things like the Action class, the Form class
etc. But the point is, after having finished the work on
the backend logic, I have to present my data in the form of
tables on the page. Now the table dimensions, the colours
used, etc. can vary based on the data
Problems with Struts 1.1, html-el, and weblogic 6.1
I have been running Struts 1.1 on WebLogic 6.1 with no problems (using both the html and html-el taglibs), until I tried to use the precompile option. If I have a page that uses the html taglib, the compilation works fine. But if I change the page to use the html-el taglib, I get this error. Any help would be greatly appreciated.

Nesting a tiles:insert inside of a tiles:put is returning Illegal to flush within a custom tag
Hello, I have a situation that I need to nest a tiles:insert inside of a tiles:put. I did this with template tags in the past with no problem. I am now getting an Illegal to flush within a custom tag error when I changed all the template tags to tiles. I have read about similar problems when nesting a tiles tag inside of an iteration tag... So, I hacked it by using tiles for the outer insert/puts, and a template for the inner insert/puts, but I shouldn't have to do this, right? Plus, I may need to use tiles for the inner insert/puts in the future and it is just ugly to mix and match this stuff... Any help would greatly be appreciated.
