Project WONDER

I guess you followed instructions on the web site at
http://wonder.sourceforge.net/start.html

If so, sorry it's my fault; those instructions are actually outdated and you
didn't have to replace the ProjectBuilderJambase. Please put the original
back and follow the instructions in other document called Quick Start Guide
(quickstart_macosx.html)  You'll find the guide in Wonder-1.0.1 pre-built
distribution. 

If you need other assistance, please let us know.

Thanks, 
Tatsuya

You may consider this a bit off-topic, but I think this list reaches many D2W experts, so...
I'm considering using D2W and Wonder in a project where the reference model is not an EOModel, but is very similar: an object graph with entities, attributes and relationships. The question is would it be possible to use another model than an EOModel in D2W?
Alternatively I could consider generating an EOModel, based on the other model, but then the issue is that editing contexts will try to retrieve data from or store to a database that is not there.
Any suggestions on how to tackle this?

Hi Rudi,

the short answer is that you could do this...but the reality is that 
you could only use the rules but none of the components, because they 
are geared heavily towards EOEnterpriseObjects. Maybe you could create 
a custom EO adaptor for your data and leverage it that way if you need 
the components, too.

I've also been thinking about this recently and thought about creating 
a "EOBeanAdaptor", which could access the data in plain java objects, 
transform them to EOs, do all the stuff in D2W and on saveChanges push 
them to the java objects again - but I didn't need this because I found 
another solution for my problem.

Cheers, Anjo

Hi Max,

thanks for taking the time to draw up a plan :)

I'm very much in favor of a release very soon; sunday's fine with me. 
As can be seen by the number of workarounds needed to get the 
mergeFile() stuff into D2WModel working again, supporting pre-5.2.2 is 
really a pain in some cases. In this case, we were relying on 
mergeFile() actually getting called, super.mergePathURL() is not 
available on pre-5.2.2 so I opted for re-implementing mergePathURL(). 
Of course, this sucks and I'd really like to remove that code again...

Cheers, Anjo

Hi

We are in the process of a new install Project Wonder in order to use 
the ERChangeNotificationJMS framework.  We would like to use FrontBase 
with Open JMS.  There is a file called create_frontbase that ends with 
the sql command:

drop table jndi_context;

Now - in the rest of the sql in the "create_frontbase" file - the "drop 
table whatever" is followed by a sql to create the table.

So - my question is - ion my newly build database - am I now missing 
the "jndi_context" table?

Or - is this a table no longer used by project wonder and this line is 
for people upgrading to the latest version?

Also, I checked the sql in the mysql build for project wonder - no 
mention of a "jndi_context" table.

Thanks for your help.

Hi there
	I'm setting up webobjects on RedHat Enterprise Linux 5 which has  
apache 2.2 installed. I've got my webobjects application running via  
direct connect, as is wotaskd and JavaMonitor.
	I've also managed to get the webobjects module compiled and  
installed thanks to the various how-to's posted around the web and  
the application is running but it cannot be access via Apache. I was  
getting the dreaded "The requested ... was not found on this server"  
message, but I switched the ScriptAlias Directive according to the  
following post from Yoshihiro Sugisawa (June06)
>
> try change 'ScriptAlias'.
> example
> #ScriptAlias /cgi-bin/ "/var/www/cgi-bin/"
> ScriptAliasMatch ^/cgi-bin/([a-z].*) /var/www/cgi-bin/$1

So now I'm getting no response from my connection - and there is  
nothing in the apache  access_logs. In the apache error_logs I get  
the following

[Thu Sep 20 15:41:05 2007] [notice] Apache/2.2.3 (Red Hat) configured  
-- resuming normal operations
*** glibc detected *** /usr/sbin/httpd: malloc(): memory corruption:  
0x000055555b1dde60 ***

Has anyone managed to get WebObjects running on RHEL5 & Apache2.2?

I'm not sure if it's related, but the include to the webobjects conf  
sits before the mod_rewrite and mod_alias as follows

>
> LoadModule userdir_module modules/mod_userdir.so
>
> Include /etc/httpd/conf/webobjects.conf
> <Location /cgi-bin/./>
> SetHandler WebObjects
> </Location>
>
> LoadModule alias_module modules/mod_alias.so
> LoadModule rewrite_module modules/mod_rewrite.so
>
Apparently in Apache2 the AddModule directives have been removed as  
there is a way to order the Module load order, but I can't find  
details to this in the documentation, and I think that mod_rewrite is  
part of the base module anyway so it's always going to be loaded first.

Hi All,

I have just converted one of my projects over to use Wonder and while  
testing the Nightly Sync function ( I spawn off a thread that  
executes every 24 hours to synchronies 2 databases ), I noticed I  
kept getting the following error message...

Database Exception occured: java.lang.IllegalStateException: Found  
null delegate. You can disable this check by setting  
er.extensions.ERXRaiseOnMissingEditingContextDelegate=false in your  
WebObjects.properties

So I did some searching and came across this response from Anjo  
discussing what causes it and what the solution is

http://lists.apple.com/archives/webobjects-dev/2006/Apr/msg00162.html

"Wonder uses an editing context factory, which is "a good  
thing" (tm). As long as you create your ECs via  
ERXEC.newEditingContext() you shouldn't have any problems."

So I went back and changed my code to :

ec = (ERXEC) ERXEC.newEditingContext();

However I still get the messages. Now I could of course just turn  
them off via the property as the error suggests, but I wanted to know  
why Anjo's suggested fix doesn't help. Does it have anything to do  
with the fact its running in its own thread not the main applications  
one ?

Hi Mike,

I don't think so, unless there is something else Im missing, but here  
is how those parts of my Application.java look....


public class Application extends ERXApplication

and

	public static void main(String[] argv) {
		ERXApplication.main(argv, Application.class);
	}

Looks OK ... Are you defining any custom delegates that are overriding  
ours?  Are you sure you have converted EVERYTHING to ERXEC?  Turning  
the warning off is definitely wrong.  This should never happen and  
it's bad if it does.

Looking at the code, if you were overriding with your own it would be  
a different error message, so that's not it.  It's gotta be that  
you're missing an editing context creation somewhere.

Hi Mike,

Yeah I figured it's probably a bad idea to just turn off the message.

As I said this is running in a thread. There is only one EC which  
looks like this....

private ERXEC ec;

...
ec = (ERXEC) ERXEC.newEditingContext();
...

Anjo's other suggestion from that old mailing list email was to  
explicitly set the Factory ( mind you he said you shouldn't have to  
if you use the line of code above ). But I thought I would give it a  
try anyways...

ERXEC.factory().setDefaultDelegateOnEditingContext(ec);

But this also doesn't help.

I receive the error message twice every-time I save the context.

Any other ideas ?

What's the stack trace from the error?  It should basically tell you  
which EC it is?  Are you extending ERXSession?

Thats the funny thing there is no "stack trace" per say. All I get  
is.....

  10:43:23,685  INFO [Thread-3] (er.transaction.adaptor.Exceptions:

NOTE: Thread 3 is the correct thread, i.e. the one that is launched  
to do the updates.

Yes. But the thread is being launched from inside Application, so Im  
wouldn't think the Session would effect it.

Hi All,

Does anyone have an example of implementing ERCoreBusinessLogic  
AuditTrail ? Or pointers on where to start  ? Reading through the Jav  
Doc and code hasn't gotten me to far. Maybe I need to start with  
ERCoreBusinessLogic itself. Like setting the Actor ?

Any help, pointers, code, examples, articles, blog posts etc would be  
most appreciated.
