Re: Newbie Help: Struts 2 + Spring + Hibernate
Ryan, I just went through a similar learning process. I found that by following the model of the online tutorial, I had a lot more luck getting started than trying to start from scratch. Load up the WTP plugins for Eclipse, grab the "quickstart" zip file mentioned in the online tutorial, and use that as your starting point. Everything will already be laid out where it needs to be. You begin to understand why and how as you start adding your own functionality to the project. It really is a good learning tool. As for the Maven commands, you could use "mvn war:war" to build your WAR file. I often use "mvn install" because it builds, runs unit tests, packages, and installs the artifact in your repository. There are easily a dozen different ways to use Maven to build at various levels. As for hibernate mappings, just don't. I've found that the JPA annotations are cleaner and, in my opinion, easier! The tutorial covers those a bit, but the more advanced annotations are not difficult to catch on to. Good luck!

RE: Newbie help with Struts idiom: functional if/else tags
Hi
I had a similar problem a while back and found that using this instead
worked:
<%@ taglib uri="http://java.sun.com/jstl/core"; prefix="c" %>
I don't know why.
Might be worth a try.

I know I'll look back on this learning curve with a head-slapping
recollection, but until then, for posterity:
1. If I remove the taglib directive in the JSP, the various tags are
copied directly into the html output, with the browser doing its best to
just ignore them. The plaintext tag body content is actually rendered,
again, the result of the browser doing its best with what it considers
unknown markup.
2. When I put the taglib directive back in, the JSP compiles and
subsequently does something with the tag directives, as the tags are no
longer copied into the resultant html and the default always
seems to execute. Nor do I receive any exception output in the browser or
in the catalina.out logfile.
Whatever is misconfigured in my app is not a completely fatal situation:
I just can't get at the scripting variables to do meaningful operations on
them.

Re: Newbie help with Struts idiom: functional if/else tags
Thank you for the reply.
1. I want to say yes, Feature is a proper JavaBean, with essentials
public class Feature {
private boolean premium;
public void setPremium(boolean b) { premium = b; }
public boolean isPremium(){ return premium; }
}
and no overloaded methods.
"features" is populated thusly
ArrayList features = new ArrayList();
Feature f = new Feature();
f.setPremium(true); // e.g.
features.add(f);
and finally, in the Action.execute() method of the associated Struts
action
request.setAttribute("features", features);
return (mapping.findForward(target));
where the request.setAttribute() is the share-with-JSP-view technique
used by the Struts book I'm reading.
2. Failing to get the to work within in
#1 above, I also tried a different tack: using instead of
to cycle through the list elements that
formerly treated:
For the same ArrayList "features", containing instances of bean "Feature"
as above and set with the same Struts Action.execute via
request.setAttribute("features", features);
I attempt
True
False
which isn't even iterating over the list items. E.g, I get one line of
html output for the tag, containing
the string literal '${feature.premium}' in quotes - as if expansion of
${feature.premium} is not taking place.
I know the issues I'm raising are very elementary, but I hope they help
someone else in the process.

Re: Newbie help with Struts idiom: functional if/else tags
I'm still stumbling on some details.
For
fwiw, "features" is put in the request scope using
request.setAttribute("features", features);
in the Action that provides data to this JSP view.
The JSP prints false for cases where I know feature.isPremium() is true.
I suspect the 'feature' scripting variable has different meanings in the
two ways in which it is being used (logic:iterate tag and c:choose tag)
Help is appreciated, and I'm on my way to get modern books on both Struts
and JSPs.

Re: Newbie help with Struts idiom: functional if/else tags
Thank you for the reply. Using, for example, seems to solve only half the problem. Using , I can see my way clear to True True which gives a crude if/else effect, but this is almost surely ill advised. I think the same would apply to , as I know of no "else" construct that goes with either. One could also perhaps use ... ... which looks a bit better. Thanks.

Re: Newbie help with Struts idiom: functional if/else tags
Use either Struts or JSTL or bare scriptlet. In your particular case you can make the decision in the bean itself. Do not print HTML tags from Java, this produces unmaintable and unportable code.

Good day. I am new to Struts, and while I am coming up to speed, I'm still struggling with what are surely common idioms. In a JSP, I want to output, say, a element body conditionally based on a given bean property. In pseudocode, I want if bean.property == true print X else print Y I examined the Struts Logic tags, but found no if/else construct, and I suspect there is a good reason for this. Does Struts culture encourage me to somehow move the solution into the bean itself, or is there a informed, stylish way to deal with this in the JSP?

Wendy, (and Struts Dev list)
Thanks again for your help. I've started playing with the JSTL tags and they
seem quite useful.
This is my first Web development project, which could explain some of my
confusion. I'm directly jumping into struts, so I'm not sure when some of my
questions are about the Struts framework or about J2EE in general.
In any case, I have a few follow up questions based on your last two emails:

I haven't found any information on configuring Tomcat 5 to work with JSP 2.0.
As far as I can tell, it doesn't need any extra configuration. In any case,
I've written code that should work for JSP 1.2, and then for JSP 2.0, but
neither seems to work.
As it stands, my application is pretty simple (I'm keeping it this way until I
learn all of the ins and outs of struts). There is a login page, which
contains a struts form. In the LoginAction class I load my ProjectsBean into
the request object:
request.setAttribute("projectsBean", new ProjecsBean());
which automatically populates the bean with the data I'd like to display. I
then forward to the projects page.
The following jsp page (using scriptlets, I know, *blch*), works, and does
basically what I would like it to do:
<%
ProjectsBean projectsBean =
(ProjectsBean) request.getAttribute("projectsBean");
Set projects = projectsBean.getProjects();
Iterator projectsIterator = projects.iterator();
Project project;
%>
Project ID
Project
Customer
Software Version
<% while (projectsIterator.hasNext()) {
project = (Project) projectsIterator.next();
%>
<%= project.getProjectId() %>
<%= project.getProjectName() %>
<%= project.getCustomerName() %>
<%= project.getSoftwareVersionName() %>
<%
}
%>
I tried coding it using the JSTL tags that you recommended, which of course, is
a lot cleaner:
Project ID
Project
Customer
Software Version
Instead of doing what I would expect, it prints out the the text of
"$(project.projectId}" instead of its value.
Note that I also tried using your JSP 2.0 recommendation, replacing the
tag with just "${project.projectId}". Same result.
Thanks again for your help, Wendy, and to everyone who responded to my earlier
post. I've forwarded this response to the list as well in case Wendy is not
available again to respond.

Any scope should work. Also make sure the Project object includes the
appropriate (JavaBeans compliant) getter methods for the properties you
want to displey.

Re: Newbie Help
Anthony, I'm still a newbie to struts myself, so take this email with a gain of salt (or 2). I put in a suggestion down below that may make your life easier if you have a lot of reports to deliver (or similiar items on what you are displaying). > -- Start JSP Code > > <% > ProjectsBean projectsBean = new ProjectsBean(); > projectsBean.populate(); > %> My personal opinion is that using this code negates the functionality of Struts (but I haven't seen any other part of your app or pretend to be anything but a newbie to struts still). My guess is that this is your problem, you might need to put inside the <% %> tags a request.getSession().setAttribute(projectsBean, projectsBean); or something to that effect. I could be wrong on this... See below for a solution that is *possibly* more adaptable. Suggestion: Anyhow, when I make reports for people to look at I give them 1 page with a drop down box with all the report names on it. Have an Actionform collect the report name and any other information the Struts Action then creates the object and puts it in the session and then below the submit button I have Table Code goes here. This allows me to maintain a minimal set of code to display any and all reports that the company ever wants. Add an item to the drop down box, they hit the submit button, the action grabs the data they want and I throw it into the session and redisplay the same page. In some cases I have multiple sets of logic tags for each report as there may be a wide variation of fields which need to be displayed. You could also use Tiles and design a jsp page for each individual report and inside the logic:present tags just put as well. I'm sure there's a number of ways to do it.

Hello, and thanks in advance for your help.
I am a newbie with respect to struts, and for that matter web development in
general. I am attempting to design a simple jsp page (using the struts
framework) to print a table of values that are read from a bean. For now, I'll
stick to trying to generate the table, and worry about any additional response
from the user later.
The following is code from my jsp, surrounded only by the opening and
tags:
-- Start JSP Code
<%
ProjectsBean projectsBean = new ProjectsBean();
projectsBean.populate();
%>
Typically you won't want to do any logic like the above in scriplets. In
other words it's better to do the above in a Servlet (ie Strut's Action)
and put your 'projects' list in scope there
ProjectsBean projectsBean = new ProjectsBean();
projectsBean.populate();
request.setAttribute("projects", projects);
However, your code will probably work if you put your projectsBean in
pageContext...
<%
ProjectsBean projectsBean = new ProjectsBean();
projectsBean.populate();
pageContext.setAttribute("pojectsBean", projectsBean);

I'd like to use as much of the struts tag libraries as possible, without resorting to inline java code. The code above does not work as I would expect it to. Any tips on where I am going wrong?

How would I do this? I upgraded all of the jars to 1.2.4 version of struts,
and copied the TLDs and DTDs, but the READONLY attribute is still not set.

Re: Newbie Help html:text conditional arguments
It's possible you just need to update your taglib declarations to use
the EL version of the tags.
