Not sure, but if you after a really good templating mechanism forget those
two and take a look at the struts Tiles extension.

Subject: JSP Include Vs. Struts Template Include


Hi guys,

Can anyone help me understand the diff. between the JSP include (say
including 2
to 3 .jsp pages in the main jsp) and Struts Template include tags.

My main doubt is  Why Struts template include tag is preferred over its
counterpart?

Confused with the pros. and cons. of both the approach.

Awaiting your powerful replies.

Can I use template library tags directly with struts-faces?

[Diego Louzán Martínez]

I'm porting a Struts application to JSF using struts-faces.
Thisapplication uses the  tags from Struts and for now I
don'twant to migrate them to Tiles. My question is: can I use template
tagsdirectly with the implementation of the request processor
ofstruts-faces (FacesRequestProcessor) or do I have to implement
somevariant (like FacesTilesRequestProcessor)?Thanks in advance.

Announce: JPlates 3.0.1 released - object-oriented template processing for Java, JSP, and Struts

[Dan Jacobs]

JPlates Inc has announced the general availability of JPlates 3.0.1.  
JPlates 3.0.1 adds template processing to Java, providing fully 
compiled, object-oriented template processing with template objects and 
template methods.  JPlates dramatically improves productivity for Java 
and JSP and Struts developers.  A free evaluation version is available.

The new features in JPlates 3.0.1 include support for using JPlates 
template components with JSPs, even more support for Struts 
applications, dynamic class and configuration reloading for JPlates and 
Struts, enhanced Ant integration, and a new template visualization tool.

For more information and JPlates examples, visit http://www.jplates.com.

JPlates 3.0.1 syntax extends Java 1.4 syntax with JPlates template 
methods. Template methods are called just like other methods, but use 
JPlates template syntax for their method bodies.  The result is 
callable, executable templates.  The template method syntax combines 
template literal text with:  substitution and i18n expressions, control 
flow statements and method calls, variable declarations and assignments, 
and output format control statements.

JPlates classes are compiled into Java to ensure 100% compatibility with 
Java. The JPlates compiler is fast and robust, and maintains line 
numbers between the JPlates source and the generated Java to support 
easy debugging. The JPlates 3.0.1 runtime provides high performance 
template processing support for Servlets, Struts, JSP, J2EE, and J2SE 
applications.

JPlates 3.0.1 offers the most usable, flexible, and powerful technology 
for dynamic content generation on the web, for XML transformation, for 
source code generation, for generating personalized email, or for any 
other application involving template-based processing.  Use JPlates 
3.0.1 along with or in place of JSP, XSLT, and other template 
processors, wherever you generate stylized text, whether in a 
web-application, a code-generator, or any other kind of Java application.

Hi experts,

my english isn´t good, so I use simple english:

I got a "template.jsp" :

<%@ include file="taglibs.jsp" %>



 

   template.jsp ;-)
  

then I got a "fahrplan.jsp":

<%@ include file="taglibs.jsp" %>
 



The "content.jsp" can start Actions and make a new Messages object, the
control is returned to "fahrplan.jsp"
What do I have do write into the "content.jsp" or ActionClass, so that
the fahrplan.jsp shows me the messages?

I tried:







The message get writen, but not to the position  in the fahrplan.jsp

sharing tiles template across multiple applications?

[Raymaker, Dora]

Hello, I've got a number of separate struts/tiles web applications which
I'm consolidating under a single login.  These separate applications
need to be kept separate because they may need to exist on different
physical servers, have different hardware needs, etc.  Also, we do not
want to have to reload everything every time one piece of functionality
changes.  However, from the user's point of view, they should all look
like a single application.

 

To that end, I'd like to have my tiles template and certain of the
common tiles (header, footer, etc.) centralized, able to be used by all
of the distinct applications.

 

Is there a way to do this?

 

Currently we are running Struts 1.0, but will probably be moving to 1.1
for the consolidation project.

 

Is there a better way of achieving the goals of 1. unified maintainable
interface; 2. single login; 3. webapps with very distinct physical
needs; 4. enable updates to a single app w/o having to touch all apps?

 

Thanks!

RE: Template Method Design

[Andrew Hill]

Quickest way I found was to cut and paste the code from DispatchAction
source into my own class that extended my base class instead of action, then
I extend my DispatchActions from that. The disadvantage is that if you
upgrade to a new version of struts you need to remember to update your base
dispatch action class.

Nowdays though i prefer not to use dispatch actions, but rather hardcode an
if statement to check the parameter in my execute and branch on that. Its a
little more typing, but I find it gives more control and is more convienient
in other ways.

RE: Template Method Design

[Andrew Hill]

I use the technique of finalising execute (1.1 equivelent of perform) and
having it do the lions share of the work for things. For example in a crud
action most of the work is occuring in execute and the subclasses just do
those things that are specific to the record type in question...

I find it works *very* well, and indeed I would suggest that for all but the
most trivial apps your wasting a lot of your own time by having any concrete
action class do ALL the work when you could be using inheritance and an
abstract superclass 'template' to take care of the generic stuff.

(Incidentally one thing Ive found useful when doing things this way is to
have the superclass execute method create
an 'ActionContext' bean that encapsulates the four parameters that get
passed to execute, and then you pass that to your subclasses. Saves a lot of
time, and gives you a spot you can add extra stuff to later instead of
having to change lots of method signatures.)


In terms of exception handling though, you may be better off using the
struts ExceptionHandler feature for dealing with exceptions thrown by
actions.

Quick template question

Hello all.

I've got the following template file:

<%@ taglib uri='/WEB-INF/struts-template.tld' prefix='template' %>

 
 
 
 
 


Is there a mechanism to have just one file rather than 2 seperate files for the 
content ? Is it possible to at least replace the line:

 

with just the html code for that page directly in this file ? And if so how would I do 
that ?

Thank you,
Stephane

Re: Required Template Variables

[Sgarlata Matt]

I'm not sure exactly what you are trying to do, but I have 2 different 
ideas you can choose from:

1) Subclass the Action class to do this for you, and have all of your 
Action classes extend from this new subclass.
2) Store this information in the session so you don't have to pass it 
back and forth with each request/response.

RE: Using Sturts-HTML tags in Template

[James Childers]

First off, it's a very good rule to not break up opening and closing HTML tags into 
separate files. Second, this is required when your tags are custom tags: the include 
file is its own compilation unit, so as far as the interpreter is concerned the 
closing tag doesn't exist unless it is in the same file.

It's far better to a) use Tiles instead of include files, and b) make a single "main" 
page that contains your  tags, body tags, and so forth. The 
sub-tiles will populate your body elements.

In any case, Jasper is doing what it should. Put your opening and closing tags in the 
same file. In the case of JSPs, it's not just a good idea, it's the law.

Using Sturts-HTML tags in Template

[Joe Krause]

I am trying to place the bulk of my navigation and HTML header code into a
header.jsp file. Each JSP view page then includes a header.jsp and a
footer.jsp file using the following:

 

<%@ include file = "/templates/header.jsp" %>

 

// Page specific implementation

 

<%@ include file = "/templates/footer.jsp" %>

 

This works great. But when I added the <%@ taglib
uri="/WEB-INF/struts-html.tld" prefix="html" %> taglib directive and made
 become  in the header.jsp file and  become
 in the footer file, I get the following error:

 

org.apache.jasper.JasperException:
/WEB-INF/jsp/admin/employee/list.jsp(16,0) /templates/header.jsp(39,0)
Unterminated  tag

 

 

Is there a way to have the  and the  tags be in
different physical .jsp files? I thought that by using the PAGE DIRECTIVE
INCLUDE versus the TAGLIB INCLUDE I would be assured that the pages would be
included at compile time and thus work.

 

Please advise!

template theme idea

[Dan Allen]

I have an idea which I think would help to make struts more flexible
when it comes to "skinning" an application.  I might get shot down
for this, but it makes a lot of sense to be, so here goes.

Currently in struts, the paths in the configuration file (and
taglibs) can follow a forwardPattern and pagePattern which in
turn can currently use two variables, $M for the module directory
and $P for the path value.  I propose to add a third variable named
$T which would be replaced with the "theme name."  The theme can be
specified as an init parameter for the servlet in web.xml and
possibly overridden by a BaseAction if a certain cookie is read in.
It looks as though the best place for the getter/setter would be in
the ActionServlet since it needs to be available to all Actions that
are created.  Better I guess would be to place it in a
THEME_NAME_KEY in the servletContext and then use put the get/set
method in the Action.

Before I make a patch I need to know where one would place this
information in order to modify.  The other issue I forsee is that
using WEB-INF for the jsp pages no longer becomes a viable option
since the path element would be 

/WEB-INF/jsp/example.jsp

doing

$M$T$P

would leave behind (in the default module configuration)

/default/WEB-INF/jsp/example.jsp

...so container security can be used instead.

The only issue I see with this in the taglibs is if you wanted to
include a "common" file to all themes.  Is there already a way to
change the pattern for creating the path in the taglibs...or is the
pattern sticky once it is set?

Dan

RE: Template VS JSP:include

[shirishchandra.sakhare]

But u are missing the obvious point...
With jsp include, if you want to change the layout, or some generic cahange, u will 
have to change all n pages..And with template u will just change 1 jsp..The template 
jsp..That is the real reason..to make the maintenance easy..

BTW, if u use tiles instead of Tmplate tags then u will have just n +1 jsps plus 1 
definition file...And it is very easy to implement..Very similar to the template...

You can combine the "use of template" and "content" pages into one JSP to
get n+1 JSPs.

Re: Problem forwarding from a Tile or Template.

[Cedric Dumoulin]

 You are going in the right direction, but you should declare the tiles 
plugin as follow in the struts-config.xml:

 
   
   
 
 This should be inserted after the  tags.

 You can check the struts-config.xml file in tiles-documentation.war as 
example.

 Hi,

 The provided code should work with Tiles if you have set the 
TilesRequestProcessor.

 The problem is that the jsp spec forbid the use of forward once the 
response is committed. But the jsp spec also said that a response is 
committed when you do an "insert()". Tiles, and Templates, use 
include(). Struts action  tag use forward(). So there is a 
problem. The TilesRequestProcessor takes care of this problem, and use 
include() instead of forward() when you use a  in a struts 
action.

I get "Cannot forward because the response has already been committed". I get the same response using Templates or Tiles. Here is a simplistic version of my problem.

one-pane-template.jsp is 
<%@ taglib uri="/WEB-INF/tld/struts-tiles.tld" prefix="tiles" %>




  

I am trying to attain a Tiled display, where one of the Tiles is a wizard. As there are a lot of initial form parameters for this app, I call the action and form to initialise the data. Hence, the ".do" call.

If I create an Action for the Tile container (one-pane-template.*) and populate the necessary beans there, calling "one-pane-template.do" and "requestCreate1.jsp" works, but this seems the wrong place to put the logic.

FYI - I initially raised this as a bug (for Templates)   http://nagoya.apache.org/bugzilla/show_bug.cgi?id=18469, but it was invalidated as Tiles had superseded it.

Re: [Q] struts-template - I centralized the layout file, but am Imissing something?

[James CE Johnson]

Hi Jeff,

I generally use Tiles to handle these kinds of things.

In your struts-config.xml install the Tiles plugin:
   
   
   
   
In your tiles-definitions.xml define your layout and other tiles:
  


 
   
   
   
   
   
 
 
 
  
 
 



Back in struts-config your actions forward to tiles instead of jsps:

 
   
 
   
 
Finally, your layout.jsp
<%@ taglib uri="/WEB-INF/tiles.tld" prefix="tiles" %>

 
   
   
   
   
 

Hope that helps a bit,
J

The only difference between the 3 files is the FOO.jsp which loads the

Now I've been able to get rid of all my structure.jsp files and replace it

I can invoke it from the struts-config.xml with an action reference like
this:

So essentially, I can now display any page that follows the standard

then invoking the MasterLayout with a tilePage= parameter to indicate which
tile should be thrown into the content section.
I have two questions:

1) Am I overlooking something that is likely to bite me?

2) Is there a more elegant way to control the filler tile?

In particular, I'm not crazy about the resulting URL line displayed in the
browser location. When I forwarded to the logon success page, I had a nice
url that just said:
http://localhost/MyAppName/LogonSubmit.do
But now that I am redirecting (instead of forwarding - to break the

http://localhost:/MyAppName/MasterLayout.jsp?tilePage=/TileWelcome.jsp
I can live with it the way it is, but I want to be sure I'm exploiting all

Problem porting JSPs with template to tiles

Using keys for template titles

[Ramtin Khosravi]

Hi,

I use struts-template taglib (not Tiles) and want to select the title of my
JSPs from the application resources. In other words, I want to use the value
of  as the key to look up a title string (like
the way we do it by ).

How can I do it? Or is there some other way to pass a parameter to the
template JSP?

Thanks,

template

[Amit Badheka]

HI All,

I am using struts templates in my project. I am including three pages in my template.

My requirements are such that I want to open a jsp page in new window (onlys that 
single page). 
Is it a right idea by the mean of MVC?

also, the problem I am having is when I tried to do this, main window gets refreshed 
on click event ( thought nothing is specified on submit).

Is anybody has any idea??

please help.

Re: Problem with Struts Template and proxy caching

[Cedric Dumoulin]

 Hi,

 I think that once the response is committed, you can't change the 
response's header (check the spec).
 So, if you set the header after the template is inserted, the change 
has no effect because the insert commit the response.

RE: Use of Struts 1.0.2 template tag doesn't display jsp errors in included files

[mech]

Solved the problem myself by migrating to Struts 1.1b2 and using the
 instead. Now I get an jsp error message in each tile and can
debug more easily.

Also solved some other difficulties with pathes to resources that can
now be context relative instead of template relative...

Use of Struts 1.0.2 template tag doesn't display jsp errors in included files

[Michael Echerer]

Hi all,

I'm using Tomcat 4.1.15 with Struts 1.0.2 and set up a framework to use templates with 
the -Tags.

I already set  but I still don't get any exceptions dumps 
if a part of jsp code is incorrect in any of the included files. 

The template part causing that error is either empty or the template is not processed 
any further which is quite difficult to debug.

Testing each inserted file separately also doesn't help me in every case, because some 
included files require beans that had been stored into the request scope by an earlier 
included file for example. So the bean cannot be found if I don't include everything 
in the correct order.

Is there any better solution for debugging jsp pages that are template generated?
What is the closest I can get to have a jsp page using any kind of includes to only 
one page which contains all the content?
Is that  + no error display problem solved if I use the  tags instead 
or will I have the same difficulties for jsp debugging?

I would like to separate design from content without considering for debugging so much 
that I don't have "just one large page". What is a better practice for that?

Thanks a lot.
Michael

Re: Template problem

[Cedric Dumoulin]

 The reason is that your action do a RequestDispatcher.forward(...), 
which is not allowed once the response is committed. This is a problem 
with the template library.
 So, you should consider to use Tiles and its ActionComponentServlet, 
which allows such insertion.

imp: frameset in template

[Amit Badheka]

Is there any way to put a jsp page that contains frameset, in template?

I tried the same but the page contents are included as it is, and not the pages 
included in frames.

template


  
  
  


template-end---

-index





  in index-
  


  
  

  
  


  
index-end--

any help will highly appreciated.

Re: frame in template

[Eddie Bush]

There are two ways Tiles will bring content in - as an include or as a 
value.  You want to bring your content in as a value (to be specified in 
your frameset), but currently your bringing it in as an include.  The 
same type of thing happens when you want to set the title for a 
document.  Go look at the example and you can't miss it (hint:  it's not 
an include!).

Re: hrame in template

[Eddie Bush]

You wouldn't want to do a typical insert for a frameset.  All you care 
about is retrieving the string representation of the file-name in your 
app's URL namespace.  See getAsString or getString (I forget which) tag 
in the tiles taglib.  There are examples on this ... (no, not frames, 
but there are examples of just getting the item as a string and not 
doing an include).

Re: [TILES] Problem using struts actions in tile's template

[Cedric Dumoulin]

 You can add a try/catch around the RequestDispatcher.forward(..) call, 
catch the undesired exception, and do an include when the exception 
happen. This should work.

Thanks Cedric, Danny, James for all of your help. I understand what you are
saying (re:forwards/includes). 

As a test I modified the struts 1.02 ActionServlet
(I love OSS:-)) to check response.isCommitted() and do a forward or include
accordingly. This works great in Tomcat. Unfortunately it does not work in 
WL6.1 SP3.  The WL response object seems to always isCommitted==false so I never do
an include and it never works :-/.  

Oh well, I guess I'll have to do the thing I was dreading most, re-writing 
the whole site templating. Ugh.

 Hi,

 Danny has well explained what is happening. The problem is that Struts 
RequestProcessor do a forward in response to the  in the config 
file. If you use the Tiles servlet, your code should work because the 
TilesRequestProcessor check if the response has already been committed. 
If yes, TilesRequestProcessor do an include instead of a forward.

 To be short, use the TilesRequestProcessor, and it should work ;-).

Re: Tiles vs Template Tags

[Eddie Bush]

Assuming a variable named booleanValue (which is a ... boolean!):

Use Tiles, the template library is deprecated in favor of Tiles 
because tiles has more functionality.

I believe using the JSTL if tag with the empty keyword will return 
true when the value is false.

Also when iterating a collection i want to check whether a value is null or

It's hard (for me at least) to determine the problem from those spots of

you are trying to do.

Pros and Cons of Hard coding a JSP page in a Struts template vs using a parameter?

[Smith, Johnathan M.]

I would like to know the pros and cons of hard coding a JSP page in a struts
template.

Which struts template is better on speed and memory?

EXAMPLE1
<%@ page language="java" %>
<%@ page import="javax.servlet.http.*" %>
<%@ page import="javax.servlet.jsp.*" %>
<%@ taglib uri="/WEB-INF/struts-template.tld" prefix="template" %>
<%@ taglib uri="/WEB-INF/cdd.tld" prefix="cdd"  %>






EXAMPLE2:
<%@ page language="java" %>
<%@ page import="javax.servlet.http.*" %>
<%@ page import="javax.servlet.jsp.*" %>
<%@ taglib uri="/WEB-INF/struts-template.tld" prefix="template" %>
<%@ taglib uri="/WEB-INF/cdd.tld" prefix="cdd"  %>



"/>


I would think that example number 1 is better and faster??  From looking at
the source code example 1 is bigger do to a include inline?

You won't notice any difference in speed or memory between the two.  Looks 
like the second one is more flexible though.  Why are you importing 
javax.servlet and javax.servlet.jsp?

You'd probably be better off using tiles as it's the more popular/developed

Re: Tiles/Template Automation

[Cedric Dumoulin]

Hi,

   Sorry for this late answer, I am abroad since 2 weeks, and have some 
trouble with my mails.

The preferred way is to use definitions defined in a centralized xml
file. This is more flexible than having some attributes hardcoded in the
jsp files themselves.

Tiles/Template Automation

[Adam Sherman]

If I want to avoid defining attributes in multiple locations, and modifying 
more than one file for each new page, how should I use Tiles/Templates?

To clarify:

I want all files in a certain directory to use the same template.
I also want the attributes, like Title, to be contained in the files 
themselves.

This means that I can add a page, simply by creating it in the right 
location.

Any ideas?

Thanks,

A.

Re: global forward and Struts template--(error)can't forward responseafter it's commited

[Cedric Dumoulin]

Hello Keven,

The error message you got says exactly what is wrong: you can't do a
forward once the response is committed.

Checking your code, it appears that you do a forward in a page inserted
by the template. This is not possible due to jsp specification.
Templates use "include" to do the insert. A side effect is that the
output stream is flushed, and response committed. So, once you have done
an include, you can't do a forward ...

Re: how to display Struts Tags inside Template Pages ?

[Keven]

Hi, Anen:

First, I want to clarify that the great sample(test.zip) was posted by Sean. We should 
thank him. Sean, are you listening us?

I had the same problem as what you have.  It seems that struts template doesn't work 
well with frame. If someone can answer this, that would be great.

Thanks.

  It's a great sample of how to work with Template in Struts.

Re: template

[Keven]

Hi,Sean, David and Cedric:

Thank you very much for your reply.
Sean, I tried with the ziped files. It works fine. Thank you very much to make it so 
clear.

Now, I am trying to use the same strategy to work with struts example(I modified the 
example for practise only). I have put all jsp files under Struts-example directory. I 
have index.jsp as following:

template.jsp
--

<%@ taglib uri="/WEB-INF/struts-template.tld" prefix="template" %>








  
  



-

index.jsp:


<%@ taglib uri="/WEB-INF/struts-template.tld" prefix="template" %>

  
  
   <%= request.getContextPath() %>/Heading.jsp
  
  
   <%= request.getContextPath() %>/tour.html
  



Heading.jsp:
---

<%@ page import="org.apache.struts.webapp.example.Constants" %>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>



  MyAccount

  

  

  join us


-
When I enter http://localhost:8080/Struts-example/index.jsp, I got the a page with 
join us on the header(top frame), and the content of tour.html on the bottom frame.

When I click Join us link at the header, I want to have 1). URL changed to 
http://localhost:8080/Struts-example/editRegistration.do?action=Create, 2)  MyAccount 
on the header(top frame), and 3)  whatever content the above URL corresponding to on 
the bottom frame. In order to achieve this, I need to implement a jsp file which uses 
the template.jsp. The jsp file should be something like:

myJsp.jsp:


<%@ taglib uri="/WEB-INF/struts-template.tld" prefix="template" %>

  
  
   <%= request.getContextPath() %>/Heading.jsp
  
  
   <%= request.getContextPath() %>/?(What should I put here)
  


My question is: what should I put in the above commented area? I tried to put 
registration.jsp. It just doesn't work.

David, you said that "Struts templates do not work with HTML frames". So we have no 
way to achieve this by using Struts template. Is my understanding right? From Cedric's 
answer, it seems there is a way in intermixed. I never used intermixed before. I will 
have a look at it.

My boss likes to use frame with Struts framework. Is it really possible to do it? or 
we have to make decision to not use frame? Your opinion and help is appreciated.

Once again, many thanks to Sean, David and Cedric.

Regards.
Keven

Personally I avoid using frameset because it results in several requests.

Tiles, and I think Templates also (not tested), work with frameset. But
you need to a well understanding of how frameset and Tiles/Templates work.
The frameset declaration look like the following:

" name="header" id="header"
scrolling="Auto">
" name="body" id="header"
scrolling="Auto">
" name="footer" id="header"
scrolling="Auto">


And your insert tag:








The key point is that the insertion of the body/header/footer is not
done with a  tag on the server, but by the frameset from the
client browser. Thus, you have one request for each inserted tiles or
region.
There is a simple example of using frameset and tiles in
tiles-documentation.war (under tutorial/).

Re: template

[David Geary]

Hi Keven,

Struts templates do not work with HTML frames; I believe that's the
cause of your problem. (If anyone has gotten them to work with frames,
please holler). When I originally developed templates, I tried to get
them to work with frames, but it was very difficult. If I remember
correctly it's because each frame creates its own request, which wreaks
havoc with templates.

That said, you really shouldn't need to resort to frames, because
templates gives you pretty much the same functionality, except for being
able to resize regions.

I don't know if Tiles (which is an extension of templates) works with
frames; my guess is that they don't, but Cedric should be able to answer
that. Cedric, are you listening?

btw, you're probably better off using Tiles or a later version of
templates. Both implementations offer similar capabilities; which you
prefer is largely a matter of taste. You can read about the later
version of templates and download the source code at:

http://www.javaworld.com/javaworld/jw-12-2001/jw-1228-jsptemplate_p.html.

RE: template

[Sean Gay]

Kevin,

Firstly let me apologise for giving you slightly incorrect information about
your problem initially. Never fear though I have a working solution for you.

Using the direct=true is correct in this case as you are putting the output
into a frameset (I missed this initially) and not including the file into
the template. This being the case you need to treat it like a string and
have the full path to the file placed in here. I think where things are
going wrong is where you may have a context path which is making your app
look in the wrong spot for the file when it tries to display within the
frameset. If you include this context path where you are outputting
"welcome.html" you should be right.

I have done this in the attached zip. If you just unzip and place in the
directory that you have your app running you should be able to see what I am
explaining.

Again sorry for the initial goose chase that I sent you on.

Regards,
Sean

RE: template

[Sean Gay]

Hey Kevin,

I think I know what is going on here.

When you are doing "" you are using direct=true which directly outputs the string
"/welcome.html" as the file to be used for the header. This would mean that
any contextPath that you have for your server is not being applied and as
such no file can be found as it is looking for it in the root of your web
server.

I think that what you should be using is something like the following which
will include the file rather than just outputting the string. ""

The same would apply for the content.

Hopefully this solves your problem. I usually only create separate files if
they are going to be used over multiple pages, such as navigation, page
headers etc. You could also do something like this to save having
superfluous files lying around.

struts template

[Keven]

Hi, All:

I would like to implement web pages using struts. the page layout consist of four 
parts: top menu, side bar, main content area, and footer. Depend on the role of users, 
the top menu will change accordingly--some button wii be disappeared, some buttons are 
added. I think this should be achieved by struts template. And for every page, there 
are two jsps, one is template jsp, and one is the jsp that uses the template jsp. I 
haven't actually implement it yet. Does anyone know the best way to achieve it? Thank 
you for your time and help.

Re: Using the template tag library with parameters like jsp:param

Hi All

Sorry for the bother - but, who knew - i.e., The issue was apparently
related to the struts "version" I was using (i.e.,
"jakarta-struts-1.0.2")...

Apparently, the examples will work only with jakarta-struts-1.1-b2.At
least in my current environment (winXP/j2sdk1.4.0_01/jakarta-tomcat-4.0.4)

Thanks!

Yes. Use the direct attribute, like this:



Then in your template, you can access that value; for example, like this:

...

Normally, the  tag will include content associated with 
the named parameter, but if you
specify direct='true' with , the  tag will 
just retrieve the value.

See http://www.javaworld.com/javaworld/jw-09-2000/jw-0915-jspweb_p.html 
for more information about templates and the direct attribute.

btw, if at all possible, I suggest that you use Tiles instead of 
templates. The former, which is an extension of the latter, has more 
functionality.

No, but you can use  as illustrated above.

Using the template tag library with parameters like jsp:param

[CB Thomas]

With jsp:include, I can pass parameter values to the included page by using 
jsp:param.

Can I get this functionality using the Struts template tag library?  If so, 
can I use request.getParameter to retrieve values in the included page?

Re: Mapping troubles with a dynamically generated template include

[Cedric Dumoulin]

  Hi,

  Check Tiles. They are compatible with templates, and accept an action 
has content. Also, you can associate a "controller" to a tile. This 
controller will populate your tile.

  Hope this help,
 Cedric

Mapping troubles with a dynamically generated template include

[Chip Paul]

My site features a "news" sidebar that is present on
every page.  It is pulled from a database.

My files use the templates and set "news.jsp" as a
content spot.





My question is: How can I have my NewsAction called
and the results populated into the news.jsp file, and
all this work in a templated mode so it appears on
every page.

I tried using /news.do as the template, but that
causes an exception when the forward gets processed
after the JSPWriter has begun writing.  I remapped
news.jsp in my struts config to auto-call the action
and forward to a different jsp file, but I still get
the exception:

java.lang.IllegalStateException: Cannot forward after
response has been committed

I'm sure this has been done since it's common in
"Blogger" type apps, but I can't find a reference to
how to do it correctly.

Thanks,

Chip

Problem using nested struts template tag

[Ying Gao]

I use nested template tag as the following:



  

  
 
 
 
 
  

  



template.jsp is a template that contains header, content and footer.
contentTemplate.jsp is a template that contains a title image and a detail
content jsp to which I pass myContent.jsp. It works fine except that the
browser (both IE and Netscape) keeps busy for a while after the page header,
content and footer are loaded. It seems that the browser tries to load
something else.
JavaScript won't work until the browser finish loading. I have no idea what
it is loading.
It only happens when I use template:put tag to pass a content
(myContent.jsp) to the nested
template (contentTemplate.jsp) without using 'direct="true"'. If I use
'direct="true"'
the browser returns immediately but that is not what I want. I want the
content to be
included instead of printed directly.
Does anyone know what the problem is? Is there any solution or workaround?
Thanks.

Iris

Re: struts template opinion

[Eddie Bush]

Yes - that's the key:  doing.  You may have to gain some insight on how 
to "plug-in" tiles to your application.  It just occurred to me that 
1.0.2 doesn't (I don't think) have the plug-in architecture.  Therefore 
... I'm not quite sure what you need to do - probably use the servlet 
included in Tiles.  Cedric is probably around somewhere and will be glad 
to clearify.  So far as the rest of the Tiles behavior (in Struts 
1.0.2), I believe it is accurately depicted by what Chuck's chapter has 
to say about it.

You'll get it!  Heck, if I can do this stuff, anyone can ;-)

Eddie

Re: struts template opinion

[Eddie Bush]

You only need to use the tiles actions if you forward DIRECTLY to a tile 
though - ie. there is no physical page and you want to forward to it. 
 Look at Chuck's chapter and try it out - and then post here if you have 
questions ;-)  Playing with it is the _best_ way to learn it.

Good Luck!

You will certainly want to visit that :-)  Chuck does a  pretty good job 
of "laying it all out".  One tip:  remember when ti comes to tiles - if 
you want to forward to them the action you use must come from 
org.apache.struts.tiles.actions.* - not org.apache.struts.actions.*! 
 Hopefully that will save you the frustration I initially had :-)

Can anyone tell me the best source of information on how to develop with

considered the best source?
