Error is as shown below. The problem is, occurring as below, this XmlWebApplicationContext need not occur, since it's injecting the bean again. How to avoid it?

[![PersistenceManager is in the war][2]][2]5 Answers
This was my stupidity, but a stupidity that was not easy to identify :).
Problem:
- My code is compiled on Jdk 1.8.
- My eclipse, had JDK 1.8 as the compiler.
- My tomcat in eclipse was using Java 1.7 for its container, hence it was not able to understand the .class files which were compiled using 1.8.
- To avoid the problem, ensure in your eclipse, double click on your server -> Open Launch configuration -> Classpath -> JRE System Library -> Give the JDK/JRE of the compiled version of java class, in my case, it had to be JDK 1.8
- Post this, clean the server, build and redeploy, start the tomcat.
If you are deploying manually into your server, ensure your JAVA_HOME, JDK_HOME points to the correct JDK which you used to compile the project and build the war.
If you do not like to change JAVA_HOME, JDK_HOME, you can always change the JAVA_HOME and JDK_HOME in catalina.bat(for tomcat server) and that'll enable your life to be easy!
The important part is this:
Cannot find class [com.rakuten.points.persistence.manager.MemberPointSummaryDAOImpl] for bean with name 'MemberPointSummaryDAOImpl' defined in ServletContext resource [/WEB-INF/context/PersistenceManagerContext.xml];due to:
nested exception is java.lang.ClassNotFoundException: com.rakuten.points.persistence.manager.MemberPointSummaryDAOImplAccording to this log, Spring could not find your MemberPointSummaryDAOImpl class.
Didn't really believe, but maven clean helped me
In my case, I'm using j-hipster and I had to do ./mvnw clean to overcome this warning.
- To closed ideas,
- To remove all folder and file C:/Users/UserName/.m2/org/*,
- Open ideas and update Maven project,(right click on project -> maven->update maven project)
- After that update the project.
