You can have a copy of the API binary with all same config files outside of your app.  And you should be able to init the database, have you done this yet?  (from the bin dir of the api binary)

 

gsh -registry -runscript

 

just checking… J

 

Thanks

Subject: [grouper-dev] Using Grouper API in a maven project

 

Hi Devs,

 

I trying to create a project which directly interacts with the Grouper Java API. The project is a maven project and I have added the following dependency.

 

<dependency>
    <groupId>edu.internet2.middleware.grouper</groupId>
    <artifactId>grouper</artifactId>
    <version>2.3.0</version>
</dependency>

I also copied the files inside the conf directory in the binary distribution into resources directory in the project and configured the correct database connections in the hibernate properties file. Also using the gsh I initialized the database.

 

But when I tried to run simple example code provided in the API.txt document I get the following error

.

.

Grouper warning: cannot find class com.thoughtworks.xstream.alias.CannotResolveClassException, perhaps you are missing jar: xstream.jar

Grouper error: grouper versions do not match, GrouperVersion.class: 2.3.0, grouper.version.properties: null, manifest: null

Exception in thread "main" java.lang.NullPointerException

After Googling for the exception message I found this grouper email thread [https://lists.internet2.edu/sympa/arc/grouper-dev/2011-10/msg00069.html] which is discussing the same issue. There is an open issue for this https://bugs.internet2.edu/jira/browse/GRP-673 and I tried to manually copy this file into my project to overcome the issue. But I cannot find the misc/version.properties file in the API binary distribution.

 

Where can I get this file? Or else your help on how to fix this issue is highly appreciated.

 

Thanks
