Ok new stuff I was not aware of !
I've just built the app on my personal mac book air, with no real WO installed (we build wo apps with gradle), and no WOBootstrap.jar is added to the woa. I said to myself it will not work without it, but to my surprise it launches the app with -classpath="all the classpath from the txt classpath files"... and of course the app launches...
But I fear the command line length limitation on certain unix....

So, especially the maven guys, do you include the WOBootstrap.jar ? And if so, which one is it ?!

Thanks for your answers

Alex

Hi,

funny thing I've got the same error at startup on my recently woinjected App in deployment only (woinject v1.0.1) :

Caused by: javassist.NotFoundException: com.webobjects.foundation._NSUtilities
at javassist.ClassPool.get(ClassPool.java:450)
at com.woinject.WOInject.init(WOInject.java:66)
... 6 more

I have no clue what's wrong. All the needed jar's are in the classpath.
Looks like there's some class loader issue in there, is there something I'm not aware of ? The WOBootstrap.jar must be the one from the wotaskd 5.4.3 ?

Thanks for your help,

Alex

This question is probably best for Henrique, but I welcome any help on this.

I am attempting to introduce WOInject to an existing large Wonder
application.

Good to hear. :)

Launching the application locally in WoLips works
perfectly, injection of some @Singletons works well.

My problems begin when the application is launched with WOMonitor. I
get the following exception trace :

Caused by: java.lang.Error: Cannot initialize the application to take
advantage of WOInject features.
at com.woinject.WOInject.init(WOInject.java:89)
at com.clicktravel.travelmanager2.app.Application.main(Application.java:23)
... 5 more

Looks like neither JavaFoundation nor ERFoundation libraries are in the application classpath.

Googling for some answers turned up this message which is probably
related to my issue :
http://lists.apple.com/archives/webobjects-dev/2012/Jun/msg00242.html

I do not quite understand the advice given in the message, so am
unclear if I am doing something wrong. I am using 1.1-SNAPSHOT of
WOInject. I am also using an AppRunner class equivalent (which does
not extend ERXApplication) which calls WOInject.init with the
classname of my real Application class (which does extend
ERXApplication).


The WOInject website is a bit outdated. The latest stable version of WOInject is 1.0.1. I'm using this version in a huge application for more than a year without problems. The problem reported by Joseph in the mentioned thread seems to be unrelated with yours. Have you tried to configure your application as described in the WOInject Setup [1] section? Something like this:

package my.app;
 
import com.woinject.InjectableApplication;
import com.woinject.WOInject;
 
public class Application extends InjectableApplication {
    public static void main(String[] args) {
        WOInject.init("my.app.Application", args);
    }
    ...
}

Does it work?

I note there is a branch hotfix-classloading on WOInject. Should I be
using this version instead?

Only if you have strange class loading problems as reported by Joseph.

Is it correct to change the WOMonitor configuration to point at the AppRunner class instead of my real
Application class?


Yes, you need to run the application from the AppRunner in this case. The original solution (described in the docs) doesn't need it.

Last year, I've started working in a framework/solution to reduce class loading problems without adding too much friction for WOInject users. I made some progress, but it's still not finished. The community interest in WOInject is a motivation for me to keep working on it. :)


Cheers,

Henrique

Any help would be gratefully received!

Thanks,
Steffan
