Description
Hello,
I'm trying to get CDI (WELD) to work on our Java EE application. We use Struts2 as front-end framework with Action classes (as controllers).
We want to be able to use CDI and inject into the Action classes but we have no success on integrating the cdi-plugin.
On weblogic server startup I get the following error:
16-Sep-2015-09:52:04 [ACTIVE] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)' [ERROR] InterceptorBuilder.Actual exception Caught Exception while registering Interceptor class com.opensymphony.xwork2.interceptor.ExceptionMappingInterceptor - interceptor - zip:D:/dev/bin/oracle/weblogic/12.1.3.0/user_projects/domains/granite_domain/servers/GraniteServer/tmp/_W L_user/granite/dajv2g/APP-INF/lib/struts2-core-2.3.24.jar!/struts-default.xml:194:116 at com.opensymphony.xwork2.factory.DefaultInterceptorFactory.buildInterceptor(DefaultInterceptorFactory.java:64) at com.opensymphony.xwork2.ObjectFactory.buildInterceptor(ObjectFactory.java:209) at com.opensymphony.xwork2.config.providers.InterceptorBuilder.constructInterceptorReference(InterceptorBuilder.java:70) at com.opensymphony.xwork2.config.providers.XmlConfigurationProvider.lookupInterceptorReference(XmlConfigurationProvider.java:1114) at com.opensymphony.xwork2.config.providers.XmlConfigurationProvider.loadInterceptorStack(XmlConfigurationProvider.java:932)
Which is caused by:
Caused by: java.lang.NullPointerException at org.apache.struts2.cdi.CdiObjectFactory.getInjectionTarget(CdiObjectFactory.java:185) at org.apache.struts2.cdi.CdiObjectFactory.buildBean(CdiObjectFactory.java:158) at com.opensymphony.xwork2.ObjectFactory.buildBean(ObjectFactory.java:178) at com.opensymphony.xwork2.factory.DefaultInterceptorFactory.buildInterceptor(DefaultInterceptorFactory.java:42)
I checked out the source code and I could see that the beanManager instance variable is NULL. This happens because none of the 3 lookups is able to get a reference to the BeanManager.
