George Gastaldi closed FORGE-1261.
----------------------------------

         Assignee: George Gastaldi
    Fix Version/s: 1.4.2.Final
       Resolution: Done


The Hibernate tools plugin already bundles freemarker as a new dependency. Freemarker has a built-in logging facade system that delegates to the underlying logging implementations (much like commons-logging). 

When the Hibernate tools plugin is installed, log4j (which is bundled with this plugin as well) kicks in and freemarker chooses the Log4j implementation. 

This is not handled correctly in the module.xml, given that declares that it depends on nothing but the javax.api.

Thanks to [~tm2] for detecting this.

> Summary:  the org.freemarker module should express a dependency on org.apache.log4j but doesn't
> Workaround:  edit modules/org/freemarker/main/module.xml and add the dependency
> The long version:
> "rest endpoint-from-entity" works fine in the version of Forge that is bundled in JBoss Tools 4.1 (Forge 1.3.3).
> However, the DTO-based functionality added in FORGE-1060 looked tasty, so I downloaded Forge 1.4.1 and took it for a spin.
> Regardless of whether I run 1.4.1 standalone or within JBoss Tools (Eclipse), "rest endpoint-from-entity" fails with
>     java.lang.ClassNotFoundException: org.apache.log4j.Priority from [Module "org.freemarker:main" 
> (I have a complete stack trace but it doesn't add anything profound).
> Once I edited modules/org/freemarker/main/module.xml and added a dependency for the "org.apache.log4j" class, "rest endpoint-from-entity" ran happily and generated the expected classes.
