Развертывание Birt Runtime 4.2.2 на Weblogic 10.3.5

Если просто задеплоить birt.war на Weblogic , получаем при старте:

weblogic.application.ModuleException:

Решение данной проблемы - закомментировать в weblogic.xml тег <prefer-web-inf-classes>:

<?xml version="1.0" encoding="UTF-8"?>
  <!DOCTYPE weblogic-web-app
    PUBLIC "-//BEA Systems, Inc.//DTD Web Application 8.1//EN"
    "http://www.bea.com/servers/wls810/dtd/weblogic810-web-jar.dtd" >
<weblogic-web-app>
<container-descriptor>
     <!--prefer-web-inf-classes>true</prefer-web-inf-classes-->
</container-descriptor>
</weblogic-web-app>

После этого приложение стартует, однако при попытке сгенерировать отчет валится:

org.eclipse.birt.report.engine.api.EngineException: Error happened while running the report.
   at org.eclipse.birt.report.engine.api.impl.EngineTask.handleFatalExceptions(EngineTask.java:2346)
...
Caused by: java.lang.NoSuchMethodError: org.mozilla.javascript.Context.initStandardObjects()Lorg/mozilla/javascript/ScriptableObject;
   at org.eclipse.birt.report.engine.javascript.JavascriptEngineFactory.createRootScope(JavascriptEngineFactory.java:74)
...

Проблема исправляется также через weblogic.xml, который в итоге принимает вид:

<?xml version="1.0" encoding="UTF-8"?>
  <!DOCTYPE weblogic-web-app
    PUBLIC "-//BEA Systems, Inc.//DTD Web Application 8.1//EN"
    "http://www.bea.com/servers/wls810/dtd/weblogic810-web-jar.dtd" >
<weblogic-web-app>
<container-descriptor>
<!--prefer-web-inf-classes>true</prefer-web-inf-classes-->
<prefer-application-packages>        
            <package-name>org.mozilla.*</package-name>
        </prefer-application-packages> </container-descriptor>
</weblogic-web-app>
