First request in session problem and a bug in WOComponentRequestHandler
Hello wo-dev,
Maybe the following problems are known to you or maybe they're even
fixed in 5.4.
I hope that someone much more experienced in WebObjects can comment on this.
Our environment is WebObjects 5.3.3 with Wonder 4.0 deployed on Gentoo Linux.
The problem:
1. An application recevies the first request in session, by which
I mean a request without wosid cookie or SID in URL
(request.isSessionIDInRequest() == false)
For example an URL bookmarked by a user in her browser.
2. The request's handler key is wo, so this is a component action
i.e.: .../cgi-bin/WebObjects/ifirma.woa/wo/2.0.0.15.1.11.3.1
or direct component access
i.e.: .../cgi-bin/WebObjects/ifirma.woa/wo/FakturaBrowse.wo
Second one little or no sense in production because it would be a nice
backdoor so we reject it of course.
But first one is handled by WO in a weird way.
3. Before WOApplication.dispatchRequest calls a proper request handler
- in this case WOComponentRequestHandler it creates a new session
completely ignoring the fact that it makes no sense :)
If by a coincidence elementID in the request is equal to one of elementIDs
on a default (Main.wo) page in the application, invokeAction is called
on this element usually resulting in a weird exception being thrown.
Strange for me is that contextID is ignored in this case, in my opinion
a new session should expect contextID==0.
In our case, the following URL bookmarked by one of our users
https://www.ifirma.pl/cgi-bin/WebObjects/ifirma.woa/wo/7.0.0.15.5
caused an application to throw the following exception:
java.lang.IllegalStateException: er.extensions.ERXHyperlink : Missing
page name.
at invokeAction(WOHyperlink.java:78)
at invokeAction(ERXHyperlink.java:56)
...
(there was no improper WOHyperlink on this page, I can assure you)
Our solution:
The following code is put into Application class,
(descriptionForRequest method is not important here).
==
private boolean isRequestForRedirect(WORequest request) {
// Only component requests are filtered
if (componentRequestHandlerKey().equals(request.requestHandlerKey())) {
// First direct component access attempts are blocked
// i.e.: /wo/FirmaBrowse.wo or
/wo/oWHEMIojtbvC0evhGU1Dt0/FirmaBrowse.wo
if (request.requestHandlerPathArray() != null) {
String senderID = (String)
request.requestHandlerPathArray().lastObject();
if (senderID.endsWith(.wo)) {
pmLog.info(Redirecting request with direct component
access attempt: + descriptionForRequest(request, false));
return true;
}
}
// Then requests with too many elements in requestHandlerPath are
blocked
// i.e.: /wo/SomethingElse/oWHEMIojtbvC0evhGU1Dt0/0.0.21.1.1.4.2.0.0
if ((request.requestHandlerPathArray() != null)
(request.requestHandlerPathArray().count() 2)) {
pmLog.warn(Redirecting request with handler path array too
long: + descriptionForRequest(request, true));
return true;
}
// Finally block all component action requests without session
information
// i.e.: bookmarked URLs like /wo/7.0.0.15.5
if (request.isSessionIDInRequest() == false) {
pmLog.info(Redirecting request without session information:
+ descriptionForRequest(request, true));
return true;
}
}
return false;
}
@Override
public WOResponse dispatchRequest(WORequest request) {
boolean requestForRedirect = isRequestForRedirect(request);
// Redirect broken requests to default direct action
if (requestForRedirect) {
WOContext context = createContextForRequest(request);
WORedirect redirect = new WORedirect(context);
String redirectUrl =
context.directActionURLForActionNamed(default, null);
redirect.setUrl(redirectUrl);
return redirect.generateResponse();
} else {
return super.dispatchRequest(request);
}
}

During research on this topic I encountered a bug in
com.webobjects.appserver._private.WOComponentRequestHandler
If the above handler receives a request with requestHandlerPath longer then
2 elements and this is a direct component access, it throws
ArrayIndexOutOfBoundsException from line 108 in the above class.
And the user will see: An Internal Server Error Has Occurred.
Just try following URLs on your applications:
.../cgi-bin/WebObjects/APP.woa/wo/xxx/yyy/Something.wo
for example:
http://www.dyned.com/cgi-bin/WebObjects/WOShowcase.woa/wo/xxx/yyy/Error.wo
(xxx, yyy and Error can be of course any strings)
My code above does not solve this bug because invoking

Re: specify port
Monitor runs on port 56789 by default. Try edit/add WOPort=mymonitorport in its Properties file inside the monitor.woa itself. The system property WOPort determines the port usually of a WO app. It can be set in Properties (common during development), assigned automatically by Monitor, IIRC configured specifically in Monitor (check Monitor instance screen), or as a launch argument.

MS SQL and NSTimestamp.DistantFuture
Hi all, Apparently MS SQL Server does not like the value NSTimestamp.DistantFuture tries to send to the database. After capturing the exact SQL and trying it out using Aqua Data Studio, I get the following error: Syntax error converting datetime from character string. The value it is trying to use is: '292278994-08-17 02:12:55' MS SQL doesn't like anything more than a 4-digit year. I suppose I could just not use NSTimestamp.DistantFuture, and pass a date like '-12-31 23:59:59' or something. Any better suggestions for a work-around?

Creating and Editing EO's
Hi all, I think it's a rather basic question, however after searching the web for sometime, I haven't found the answer yet. I have made a D2W application, in which I want to have a few differences between creating a new EO and editing an existing EO. Particularly, when creating, I want the user to be able to provide a value for the database primary key through a D2WEditString, and when editing, I want the user not to be able to edit them at all, through a D2WDisplayString. I thought doing this adding a few rules with the assistant for such cases. However, it seems that there is no way in D2W to distinguish between editing an existent object, and creating a new one, as it uses the same page and the same task. Is this really true? I can't believe, there's no way to make this small differences. Any suggestions of how I can make this work? -- Atentamente, Cuauhtemoc Hohman ___ Do not post admin requests to the list.

Re: ERXMutableArray fields in Entity Modeler
Hi Ray,
Thanks for your response, and yes, I think you understand. I was
hoping to not have to create a new table with just a boolean column
along with a relationship and that I could somehow just store an array
in one of the attribute fields directly for the same effect. I
assumed that's what ERXMutableArray class was for. If not that, then
what is it usually used for?
Thanks,

From: Jeff Schmitz [EMAIL PROTECTED]

To: WebObjects Mailing List webobjects-dev@lists.apple.com
Hello,
I've taken Dave's SooperSeekrit Screencast project as a starting
point to start playing with EO objects using the Wonder Framework.
Using Entity Modeler (with Frontbase prototypes), I've added an
ERXMutableArray to one of my classes that I want to use as an array
of Boolean's in my code. In this case, what do I need to put as the
Value Type? Also, for the width, will it be 4 bytes X the max
number of Booleans to be stored?
snip
I have tried just leaving these fields blank.
Then using the following code, I'm able to create a User object ok,
and it shows up in my database with the Boolean array as a Blob:
Group group = Group.fetchRequiredGroup(ec, name, user);
Boolean [] bools = {true, false, true};
ERXMutableArray boolArray = new ERXMutableArray(bools);
User.createUser(ec, boolArray, first, last, password, newuser,
group);
ec.saveChang es();
However, when I try to a fetch from the DirectAction class as follows:
EOQualifier qual =
User.USERNAME.eq(username).and(User.PASSWORD.eq(password));
User user = User.fetchRequiredUser(ERXEC.newEditingContext(), qual);
I get the following exception on the User.fetchRequiredUser line:
Apr 16 22:31:32 SooperSeekrit[49595]
(ERXDatabaseContextDelegate.java:105) INFO
er.transaction.adaptor.Exceptions - Database Exception occured:
java.lang.ClassCastException: er.extensions.ERXMutableArray
I'm guessing it has to do with the missing fields?
Thanks,
Jeff
I might be misunderstanding your question or what you are trying to
do. But I think that you are not going to be able to do this as you
describe.
The picture you show is for the Properties of an attribute value. In
other words, if you are returning an array of booleans, then you
somehow have a to-many relationship that is returning some number of
value attributes. Those value attributes are of t ype boolean. The
relationship is, in an object-oriented sense, an attribute also. But
it is not a value attribute.
If you look at a relationship in a model, and look at its
Properties, you will see what can be done with a relationship.
Does this make sense?

I would need to see the full stack trace of that exception to be able to diagnose further why you're getting a ClassCast, though. I believe you also have to replace the entire array when it changes (meaning setArrayOfBooleans(arrayOfChangedBooleans)) -- I don't think EOF likes mutable values, but maybe there's some trickery inside of Wonder specifically for ERXMutableArray, I'm not sure. I've never used this class though ... Maybe Anjo knows, but his weekend apparently starts on Thursday (something about Americans being #1, and Germans not ...

Re: I wonder if you have seen this before: exec: -X: invalid option
I don't recall either, but I do recall seeing this. I think it was
something simple, wrong version of the JVM marked as default, no
default. something.
For a quick hack, you should be able to edit ~/Library/
wobuild.properties and add
jvm=java
Before you do that, try running the build with ant -verbose -debug and
see if you see anything that looks like a problem.

Store a 32 bit integer and you have 32 booleans and you can provide accessor methods in your business logic that returns the info however you want. You can even use KVC so that some arbitrary labels match up with specific bit positions. You can write all the accessors (for better documentation) or use objectForUnboundKey (check the doc for exact) to respond to an
arbitrary KVC to your object.There are lots of ways to do it. Some might be less workable in the future, but it depends on what you need to do.- rayOn Apr 17, 2008, at 3:35 PM, [EMAIL PROTECTED] wrote: Original Message Subject: ERXMutableArray fields in Entity Modeler From: Jeff Schmitz [EMAIL PROTECTED] Date: Thu, April 17, 2008 4:20 am To: WebObjects Mailing List [EMAIL PROTECTED].com Hello,I've taken Dave's SooperSeekrit Screencast project as a starting point to start playing with EO objects using the Wonder Framework.

In other words, if you are returning an array of booleans, then you somehow have a to-many relationship that is returning some number of value attributes. Those value attributes are of t ype boolean. The relationship is, in an object-oriented sense, an attribute also. But it is not a value attribute.If you look at a relationship in a model, and look at its Properties, you will see what can be done with a relationship.Does this make sense?- ray erxmutablearray.jpg ___Do not post admin requests to the list.

Problem with bindings to application class variables using WOLips in 5.4.1
I have moved an app to Eclipse/WOLips and WO 5.4.1 under Leopard. I
think everything is working except for this last issue. Any component
page that has a binding to an application class variable is throwing
an unknown key exception.
WorkerThread2
com.webobjects.appserver._private.WOComponentRequestHandler:
Exception occurred while handling request:
com.webobjects.foundation.NSKeyValueCoding$UnknownKeyException
message 'com.webobjects.appserver.WOApplication 0xb7c63f
valueForKey(): lookup of unknown key: 'stateList'.
This class does not have an instance variable of the name stateList or
_stateList, nor a method of the name stateList, _stateList,
getStateList, or _getStateList
I have in my application class a number of lists setup for various
popup menus that I reuse in several components. One of these is just a
list of state abbreviations. In my component wod file it is bound as
application.stateList.
In Application.java I have.
public class Application extends ERXApplication {
public NSArray stateList;
Anyone seen this before and know what causes it? I have cleaned the
project and all my bindings to the session class seem to work fine and
I don't really know what would make this different. Is there some kind
of project setting that would cause this. I must admit to being
thoroughly lost in the Eclipse/WOLips environment.
Thanks,
Kevin ___

That seems quite true to me, com.webobjects.appserver.WOApplication
does not, in fact, have stateList. :-)

I'd guess that you have something messed up in the launcher: no main
class selected, the wrong default directory, your application is in a
package but this is not sent in build.properties of your application.
When WO can find your Application, it defaults to
com.webobjects.appserver.WOApplication. This is almost never what you
want.

Re: I wonder if you have seen this before: exec: -X: invalid option
I think I had raised this issue on one of my failed deployment attempts.
my MacOSXClassPath.txt had
jvm=${jvm}
I just fixed it there now just rsync around the working file. I could
never get that file correct in my deployment straight from eclipse.
Granted I haven't tried in a few years.

For a quick hack, you should be able to edit ~/Library/
wobuild.properties and add
jvm=java
Before you do that, try running the build with ant -verbose -debug
and see if you see anything that looks like a problem.

I have another plain HelloWorld app and I don't see this error.
Where in Eclipse are the flags passed into java? It's not in the
script, it's not in the WO tab of the run configuration. Any
thoughts?
Thanks, much obliged.
