Treeview - Frameless Layout in struts
Folks,
I am developing a J2EE based data oriented application using Struts.
I want to develop a UI using Frameless Layout For Tree view, something like left side of the page will have a Tree View and depending on selected node right side of the page will be filled up with different forms for inputting/submitting/viewing the data in html.
Can some one please point out me to some examples of Tree View Implementation used in JSP for left pane navigation ?
I know Echo framework has this inbuilt functionality, But I want to develop this using struts.
Any suggestions using JavaScript or ready to use tags are welcome.
Thanks !
G

I think struts-menu (http://struts-menu.sourceforge.net) might suit your
needs.

You can/should do both: use PL SQL and make it light and make it
seperate DAO. Look at the DAO implementation and sample PetStore on
iBatis.com.

Joe,
calling PL/SQL stored procedures is certainly a way to do it, but as you
said.. the db layer should abstracted as much as possible...
I have some ideas of how to do it, but was looking around to see if somebody
knew something about that... or had other ideas...

In common usage, your Struts development
shouldn't need to know anything about your
database layer; after that, you might get better
answers from a PL/SQL user forum.
I have certainly used Java to call PL/SQL stored
procedures before, but not in a way that is
specific to either Struts or PL/SQL; I simply
used java.sql.CallableStatement.

RE: Struts and PL/SQL
Posted by Robert Taylor <rt...@mulework.com>.
If your trying to avoid the overhead of EJB, then you may want
to look into the Spring framework. I've been wanting to find a
flexible architecture/framework which allows me to start with a
non-EJB type of approach and easily scale to using an EJB container
while minimizing the impact on the application.
This article may provide some insight:
http://www.theserverside.com/articles/printfriendly.tss?l=SpringFramework
I would still advise wrapping your dataccess code in a business delegate or
application service instead of binding your Struts Action to the business
logic implementation.

Re: Struts and PL/SQL
Posted by "Daniel H. F. e Silva" <dh...@yahoo.com>.
Lucas,
Are you talking about PL/SQL stored procedures? Considering that, i recommend setting a DAO layer
up. And i do recommend using iBATIS DAO and SQL Maps for that. Resources about iBATIS can be found
at www.ibatis.com and www.reumann.net (Struttin' with Struts).
Cheers,
Daniel Silva.

Hi all!
I´ve been using Struts a lot with EJB and Hibernate with no problems.
But I always wondered if it´s possible to use an architecture that uses
STRUTS and goes directly to PL/SQL for the database layer. I know it is
possible in many way, but I would like to know if there is any special
product or package that integrates with PL ( the only one I found is
http://portalstudio.oracle.com/servlet/page?_pageid=473&_dad=ops&_schema=OPSTUDIO ) ... any pointers?
Thanks a lot

RE: Setting html:hidden property using JSTL
Posted by Robert Taylor <rt...@mulework.com>.
I believe the reason it's not populated in the
action form is because its in the request as an attribute
and not a parameter.
<snip-from-original-post>
I just started experimenting with jstl and i'd like to
set a hidden field on MyActionForm using a value
(contentId) available as an attribute on the request.

RE: Setting html:hidden property using JSTL
Posted by Kris Schneider <kr...@dotech.com>.
Small clarification that the Servlet 2.4/JSP 2.0 specs don't include/require
JSTL. Although a given container may include a JSTL implementation (like Resin,
I believe), it's not a requirement. For example, Tomcat 5.0 does not include a
JSTL implementation. For JSP 1.2, use JSTL 1.0. For JSP 2.0, use JSTL 1.1. As
Robert illustrated, the taglib URIs are not the same for the two JSTL
versions.

RE: Setting html:hidden property using JSTL
Posted by Robert Taylor <rt...@mulework.com>.
I'm sorry, I've missed parts of this thread, but this
last message caught my eye when you said it's printing
${contentId} to the screen instead of the value of contentId.
Which servlet spec. does your container support? I've seen this
type of behavior when the container supports Servlet Spec. 2.4 but
the web.xml file is referring to the 2.3 dtd.
If your container does support the 2.4 spec, then make sure your
web.xml file has
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
in its root element.
Again, if your container does support the 2.4 spec, then you
shouldn't need any .tld files or even jar files for JSTL.
All you should have to do is add (or include) something like this to the
top of your .jsp page.
<%-- JSTL Standard Tags --%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt" %>
If your container does not support the 2.4 spec, then you will need
to include the appropriate .tld and .jar files and update your web.xml
file to reference the appropriate .tld file(s).

Re: Setting html:hidden property using JSTL
Posted by klute <so...@yahoo.com>.
Hello All,
I *really* appreciate your help. Because of a
hard-pressing work deadline, i actually gave up on
getting that to work using JSTL and ended up using the
ugly <input type="hidden" name="contentId"
value="<%=request.getAttribute("contentId")%>"/>
instead.
I'll definitely come back to JSTL at a later time
since i consider that to be a proper way of doing this
sort of things.
Robert, if ${contentId} is available as an attribute
(which it was) and not as a parameter, i would expect
it to produce null or something instead of literally
printing out ${contentId} string...
Rick, i tried creating a var in the jsp and the result
would still be the same: the value of the hidden
property was printed out as {$myVar}. And, if i do
c:out in the begging of the jsp, i do get an actual
int value printed. weird... i definitely need to spend
more time doing my homework to understand how it
works...
All the best,
James

Not sure. If you have
- struts-el jar included
- proper definition of the tld in web.xml
- proper declaration for the tld on top of the page
then using it as:
<html-el:hidden property="contentId" value="${contentId}"/>
should be fine.
The only thing I'm still concerned about and maybe somehow it's related
is that contentId has to be a property of your ActionForm or else Struts
would complain that it couldn't find the property 'contentId' Are you
maybe creating the "contentId" var dynamically first in the JSP page and
then trying to set as above? "Usually" you don't need to do like you are
doing (setting the value) since that value can be set before you get to
the page and thus just doing <html:hidden property="contentId" would be
fine.
What does <c:out value="${contentId}"/> produce on the page (or in
source) when placed right before the html-el hidden tag?

Re: Setting html:hidden property using JSTL
Posted by klute <so...@yahoo.com>.
Thanks a lot to all who responded!
So i tried using html-el using the syntax Rick
suggested:
<html-el:hidden property="contentId"
value="${contentId}"/>
The resulting html contains:
<input type="hidden" name="contentId"
value="${contentId}">
This are the tagligs i am importing on this page:
<%@ taglib uri="/WEB-INF/struts-bean.tld"
prefix="bean" %>
<%@ taglib uri="/WEB-INF/struts-html.tld"
prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-html-el.tld"
prefix="html-el" %>
<%@ taglib uri="http://java.sun.com/jstl/core"
prefix="c" %>
What am i doing wrong?
Thanks a lot,

Use the html-el tag instead of the html tag. Then you can do:
<html-el:hidden property="contentId" value="${contentId}"/>
Much cleaner.
Although remember it might even be easier/cleaner to simply make sure
contentId is in your ActionForm .. then you can just do...
<html:hidden property="contentId"/> and it'll set the value for you.

R: Setting html:hidden property using JSTL
Posted by Amleto Di Salle <di...@di.univaq.it>.
Hi,
yes you can use the EL but depends on the Web Container you are using.
If you have a Web container JSP2.0 (and 2.4 servlet) compliant (for
example Tomcat5.0.x), you can use JSTL 1.1 (if you want to use them you
have to set your application)and html Struts standard.
In order to use, this version you have to do the following in the jsp
page:
<%@ taglib uri="http://jakarta.apache.org/struts/tags-html"
prefix="html"%>
<html:hidden property="contentId" value="${contentId}"/>
But if you have a WebContainer JSP1.2 compliant (e.g. Tomcat 4.x) you
have to use the html-el version + JSTL1.0. They are in the "contrib"
directory inside the struts directory. But in this case the procedure in
order to use them is just to complicate.

Oggetto: Setting html:hidden property using JSTL
Hi All,
I just started experimenting with jstl and i'd like to
set a hidden field on MyActionForm using a value
(contentId) available as an attribute on the request. Basically, i'd
like to do something like this:
<html:hidden property="contentId" value="<c:out
value="${contentId}"/>"/>
Which does not work. Should i be using EL syntax
instead? And what would the correct syntax be?
I did check that <c:out value="${contentId}"/> returns
a valid value so my confusion is just passing it as a
value to the html:hidden property.
Any help is greatly appreciated.

Subject: Treeview - Frameless Layout in struts
Folks,
I am developing a J2EE based data oriented application using Struts.
I want to develop a UI using Frameless Layout For Tree view, something like
left side of the page will have a Tree View and depending on selected node
right side of the page will be filled up with different forms for
inputting/submitting/viewing the data in html.
Can some one please point out me to some examples of Tree View
Implementation used in JSP for left pane navigation ?
I know Echo framework has this inbuilt functionality, But I want to develop
this using struts.
Any suggestions using JavaScript or ready to use tags are welcome.
Thanks !
G
