Subject [jira] [Commented] (WW-4911) JSONResult exception in struts2-json-plugin-2.5.14.1.jar
Date Sun, 21 Jan 2018 09:07:01 GMT

    [ https://issues.apache.org/jira/browse/WW-4911?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16333425#comment-16333425
] 

Yasser Zamani commented on WW-4911:
-----------------------------------

Please define
{code:java}
import com.opensymphony.xwork2.inject.Container;
import com.opensymphony.xwork2.inject.Inject;

public class MyTestAction {
@Inject
public void setContainer(Container container) {
Object o = container.getInstance(JSONWriter.class, "struts");
}
}{code}
then see if {{o}} is null or not?

Also pease configure log4j2 with {{DEBUG}} level for your app and set {{devMode}} to true
and see output for any warning?

It seems Struts could not load beans from xml there.
