Multi-page form
Is storing an object in the Session the best way to handle a multi-page form where people might use the back button to go back (assuming I set the pagecache to 1). The reason I am using a session instead of DirectAction is becuase it's a really long form and users will likely leave the form and come back later. I plan to store the sessionID in a cookie if allowed. Dan ___ Do not post admin requests to the list. They will be ignored.

Re: Binding question
Using WOLips' new add key method, WoLips automatically generated the

private String firstName;
public NewWindow(WOContext context) {
super(context);

OpenLaszo & WebObjects
If anyone can answer the questions on my post, that would be great.
http://blog.benkolive.com/2008/03/openlaszlo-webobjects.html
Well, when I started investigating what tools I was going to use to
develop my site, I discovered OpenLaszlo. Of the free tools I have
investigated so far, it is by far the easiest and quickest way to
develop a very attractive front end. And it's completely object-orient
which should make WebObjects folks feel right at home. Furthermore, it
deploys as a JSP. It gets better and better. Well almost...
OpenLaszlo has several ways to get data into its front end. It can
read XML files and through JSP servlets it can access any JDBC
database from what I could tell. Now for a WebApp where the user just
retrieves information (e.g. real estate listings), one could create a
WO app with DirectAction methods that return XML. Great!
However, I would imagine that's not the best way to make a fully
interactive app. Well, according to the OpenLaszlo ("OL")docs, they
have a Java-RPC. From what I can tell, your OL app (since it is a
servlet itself) can access the objects of other Java classes as long
as the classes are in the the OL app folder. Unfortunately, I'm not a
Tomcat, J2EE, JSP (whatever) expert...heck, I'm barely a novice. So I
have no idea how one would actually accomplish this.
But the thought of it is surely exciting. Instead of worrying about
SOAP or XML, being able to directly access our WO Objects would be the
greatest thing since sliced bread. If anyone who has done this or
might have an dea of how to do it. Please post a step-by-step
tutorial. You would be my saviour and when I sell my app to Google for
$832 million, I'll make sure you get a piece of the pie!

Re: Proble with tutorial
Well Gus, after all these emails, I'll throw in my beginner's advice
that I learned today. Use WO 5.3.3 It seems that 5.4 still has bugs
that need to be worked out.
I was having problems after I "upgraded" (or should I just say
changed) today to 5.4. And had many problems with the SQL in Entity
Modeler. Download the WebOjects 5.3.3 update and use a package
extractor to get all the frameworks. Download the Wonder 5.3
Frameworks and put those in place. Since I've gone back to 5.3.3 this
evening. No problems at all!
(Now, I'll give those migration tools a shot.)

I was only saying that the FrontBasePlugIn from Project
WOnder has no
problem with WO 5.4. If you installed Project WOnder and
included the
plugin from /Library/Frameworks it should be the one from
Wonder.
I haven't followed the rest of the discussion, so I don't

Re: Another EO question
Wow, thanks for all of that. That's way too much for such a newbie
like me. I'll wait until I get more comfortable with programming WO in
general.
OK, more important question though asked earlier but never answered,
why is Entity Modeler putting double quotes ("myColumnName") around my
column names when generating SQL command? When I try to execute then,
I get errors. When I change my frameworks back to 5.3, it stops
putting the quotes and generates the SQL just fine! Did I forget to
do something?

Re: A little bit of Ajax in a 5.3 app?
OK Mike, I've now spent 1/2 hour looking for documentation on how you added the "key" to your .java file in your video from the wod editor. I'm a newbie to Eclipse and for the life of me I can't find a command or keyboard shortcut that does that. This question goes back to the thread about devtools. I have always tinkered with WO because it was so easy for a non-programmer like me. I am trying to learn WOLips and Eclipse. One way is by going step by step through the old Apple Docs and trying to repeat functionality in Eclipse. The autocompletion nearly replaces the ability to quickly bind objects to EO attributes. But my question above and your use of something that's so basic and also so undocumented (unless I am completely missing something) is probably one reason that non- programmers are attempting to hold on to the old tools. You experienced WO/Java programmers should take it easy on the rest of us hobbyists (as we were called). And instead of lambasting us and telling us to "Just switch already," help us. I really like WO because I have been able to quickly build little databased web apps. I tried using Rails, and found that to be a disaster. The arrogant folks at 37Signals assumes that everyone who wants to make dynamic websites must be experienced programmers. Unfortunately, since I upgraded to Leopard, I had no choice but to learn to use WOLips. But what so many of you "real programmers" take for granted, I haven't a clue. Lately, I have seen answers to questions like, "just look at the Javadocs" with no further explanation among the many very helpful posts. That sort of "What an idiot you must be when the answer is right in front of you" is completely ignorant of the fact that not everyone knows what to do with the documentation and that some of us, especially me, learn more by example, than by reading the JavaDocs. Mike's video is clearly an example that using Eclipse/WOLips is fast, even faster than the old tools and for the first time I now see how I can use Ajax in my WebApp. What a great example. More please.

Caveats: This is completely unscripted, and just recorded straight through without any cuts, and to top it off, I didn't actually really PLAN what I was going do to beforehand, so the couple uncomfortable pauses are me trying to decide what I actually wanted to show -- nothing but the highest quality from Team Wonder :) .

Re: looking for relationship examples
I would start by reading an introduction book to WebObjects. Each one deals with this topic. In case you can't find one, start with Apple's documentation: http://developer.apple.com/documentation/DeveloperTools/WebObjects-date.html#/ /apple_ref/doc/uid/TP3440-TP3436-TP3592 Although examples of the mechanics of how to create a relationship mostly refer to using WebObjects with Xcode which of course has been deprecated, the theory is the same. You just need to apply the same ideas in Wolips. In Wolips, it's just as easy, right click on one of the tables involved in the relationship and select "New Relationship" select your fields and your done! If you know nothing about relationships and Enterprise Objects though, again start with either Apple's Documentation or a book. My favorite beginner's book, Josh Marker's WebObjects 5, is out of print though you can find it at some libraries. Can't PeachPit print on demand? But there are others.

Re: DirectAction & User login Questions. [Solved]
Well I discovered my problem here. Very stupid of me. For some unknown reason I selected ERXApplication instead of Application when WOLips asked me which class containing main. Obviously I selected ERXApplication. And then just kept hitting the run button. Finally, I did a run as instead and then selected Application. And now the initialization code works and is defaulting to DiractActions!

Re: DirectAction & User login Questions.
I think people might have misunderstood what I was trying to ask.
Specifically, I thought that this line:
setDefaultRequestHandler
(requestHandlerForKey( directActionRequestHandlerKey() ));
was supposed to set the default handler to "wa" so when I type into my
browser http://127.0.0.1:5/cgi-bin/WebObjects/Benko.woa the
console should return a "false" based on the code below. Instead it
returns true. It does return false when I go to http://127.0.0.1:5/cgi-bin/WebObjects/Benko.woa/wa
though. So it seems to me that the default handler is still "wo"
and isn't getting set to "wa".
public class Application extends ERXApplication {
public static void main(String[] argv) {
ERXApplication.main(argv, Application.class);
}
public Application() {
NSLog.out.appendln("Welcome to " + name() + " !");
/* ** put your initialization code in here ** */
setDefaultRequestHandler (requestHandlerForKey( "wa" ));
}
}
public class DirectAction extends ERXDirectAction {
public DirectAction(WORequest request) {
super(request);
}
public WOActionResults defaultAction() {
WOComponent page = pageWithName(Main.class.getName());
return page;
}
}
public class Session extends ERXSession {
private static final long serialVersionUID = 1L;
public Session() {
}
}
public class Main extends WOComponent {
private static final long serialVersionUID = 1L;
public Main(WOContext context) {
super(context);
System.out.println(hasSession());
}
}
my Main WO:
Untitled
Hello World

Right - it's just so easy to get a session with these ... Something
to be careful about, lots of the dynamic input elements create
sessions.

You need to be careful that nothing you are doing in Main is causing
a session to be created. Try putting a breakpoint in the session
constructor to understand why this is happening. The default DA
should look for the authentication details and respond with the
right component if the authentication was successful; otherwise
return Main without doing anything that could create a session.
On the WebObjects Wiki/confluence, it is stated that people typing
in URLs with your components could cause problems. So how do I keep
people from doing so?
See my framework "LEWOStuff"...
LEWOApplication.createRequest(..)
This has a javadoc note about it.
If I have a user/passwords login app, how do I keep people from
using a common username and password simultaneously on different
computers? There will be multiple application instances, on several
servers.
Can you define what you want here -- you want people to be able to
login from only one client host using a web browser?
cheers.

DirectAction & User login Questions.
Hi,
I am working on a pretty significant WO App and you will likely see
lots of questions from me over the next few weeks (months). I've done
some minor apps, and am no WO genius.
So Question 1,
I want the app to create no session until a user successfully logs in.
Based upon what I have found this is the right way to do it:
public Application() {
NSLog.out.appendln("Welcome to " + name() + " !");
/* ** put your initialization code in here ** */
setDefaultRequestHandler
(requestHandlerForKey( directActionRequestHandlerKey() ));
}
However, after doing so I run my app, and it goes straight to main and
creates a session. I know this because I have a string bound to
hasSession(). When I manually add wa to the URL, the same page says
false to hasSession().
WO 5.4, Latest Project Wonder, WoLips, and Eclipse, OS X 10.5.
Question 2:
On the WebObjects Wiki/confluence, it is stated that people typing in
URLs with your components could cause problems. So how do I keep
people from doing so?
Question 3:
If I have a user/passwords login app, how do I keep people from using
a common username and password simultaneously on different computers?
There will be multiple application instances, on several servers.

Re: No database connection
Sure, sorry about that. After one builds his application and creates his .jsp file per Apple's docs, one of the products in the Servlet Resources->WEB-INF folder will be a doc called web.xml. In it you will find the following: The data source to be used by EOF. If there are multiple data sources, then the definition below must be used to configure which JDBC URL (Model) should use which data source. If EOF should use a JDBC driver directly, this section must be commented out jdbc/DefaultDataSource javax.sql.DataSource Container Since I used XCode to create my EOModel and I specified the connection in it when i set it up, I just commented this section out as it says to do in the description. And Viola! my app works beautifully. Sidebar, I've seen some posts (including my own) about how to use WebObjects with OpenLaszlo. While I am sure there are several different ways (SOAP, XML-RPC, etc) I am using JSP as a go between. So far I got it to populate a window of info from a WebObjects component. Next step (no pun intended) will be to invoke direct actions (e.g. add, edit, delete). Should have that test done tonight. If there's an easier way, I could find no tutorial or combination of tutorials to show me the way.

JSP with WebObjects Question
I am trying to figure out if I can use a particular combination of JSP and WebObjects. I have read and understood Apple's Docs reagarding this but it doesn't give an example of what I want to do. From within a JSP, can on access a method create in WO without returning a WO html page. For example: I have a WO Component that grabs data from OpenBase, shows the data in a WORepitition, and has Update, delete, and Add buttons and associated methods. Now I want to use a JSP the get the data from WO, and the JSP to be able to invoke those methods. I am trying to do this because I have another app that works easily with JSP and getting it to work with WO is way beyond my abilities.
