Thanks, John,

Well, I did take a look at this, but how do I debug a maven built war app? It runs fine with WOlips as an ordinary WOApp. 
In WAR case I just keep guessing what's wrong and i don't get much info from a reverse engineered class. Especially when I am new in WebObjects. Unfortunately, this is extremely unproductive.

I'm not a maven user, so I can't help in that regard.  I think you first step should be to fire up jad or jd-gui and see what is causing the NullPointerException.

Hello,

just wanted to bump the thread. 

Sorry again for responding with a very long delay. As I said, email filtering settings were misconfigured. :)

Would appreciate your help!

Hello,

Thanks, John and Michael for your answers. 
Sorry for a very delayed reply. Unfortunately this message was filtered out by accident with other wo conversations.


To be specific - I want to build a true WAR app with maven.
I tried to follow your suggestions, but they didn't work - I still get the same error as in the first post. Let me explain my steps in detail.

1. After building war with maven I get MyApp.war archive [1]. Inside, empty META-INF folder. WEB-INF/lib contains all WO, 3rd party and MyApp.jar libraries.
MyApp.jar structure can be seen in target/classes . 

2. My Info.plist is in [2]. The problem is, I can not find any documentation on the requirements so I had to use Wonder Source framework as an example. Also, I am not sure why paths are like Resources/Java while there are no Java folder inside  Resources (Ajax lib for instance).

3. Web.xml is almost identical to yours, Michael, with the exception of (that doesn't exist):

                <listener>

                                <listener-class>com.commoditrack.core.SystemPropertiesHelper</listener-class>

                </listener>


I assume it is optional.


4. Is there any way to debug paths/missing resources?


Your help is much appreciated.


Regards,

Gintautas

Hi Gintautas,

 

I went through the same struggle last year.  Below are working configurations for a true war app built with maven.

 

Notes:

·         The below configuration is for a wonder project (i.e. uses the ERXServletAdaptor, etc)

·         Make sure you have a correctly templated Info.plist under your Resources directory

·         If using maven to build the war, I suggest avoiding the WO/wonder plugins; they aren’t required and can be nettlesome.

 

If everything works correctly, you should be able to plop your war file into the webapps directory of a tomcat and watch it run.

 

Hope this helps,

Mike

The default build.xml file (non-maven) you get with a new Wonder Application contains a war target.  It should just work.

Hello all,

 

I am trying to build a true WebObjects WAR. Unfortunately, no luck so far.

 

Is this tutorial is still valid?

http://wiki.wocommunity.org/display/WOL/Packaging+WO+Applications+as+true+WAR+with+Maven

 

So now I have a maven project that builds my app.jar and packages it into a war (including ALL libraries).

 

Initial project was created with archetype plugin as woapplication with true war support.

 

Please, could you provide me with any hints what may went wrong. I would really appreciate more documentation on this.
