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?

Then we have a bunch of context xmls available in the folder "CONTEXT".

PersistenceManager has that class:

This was my stupidity, but a stupidity that was not easy to identify :).

Problem:

  1. My code is compiled on Jdk 1.8.
  2. My eclipse, had JDK 1.8 as the compiler.
  3. 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.
  4. 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
    1. 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.MemberPointSummaryDAOImpl

According to this log, Spring could not find your MemberPointSummaryDAOImpl class.

Hey, I know that error is turning up, but that's not the issue! It's in my pom. I Will update the pom and the screenshot having the class. That's not the issue. The issue is with this: WARNING: Exception encountered during context initialization - cancelling refresh attempt – Cannes
Can you verify that this jar (with this class in it) is available under your WEB-INF/lib folder in the Tomcat working directory? – Pylorus
The Jar does exist with the class in the lib folder. I am not able to upload the screenshot for some reason. But yes, ofcourse, it does exist. The problem I see is, it's not able to cancel refresh and hence the bean is getting injected again and there it throws an error. – Cannes
@Cannes : I am facing the same issue.Did you find any solution? – Tractate
@RockingDev: Check my answer above, mine was because the tomcat in my eclipse was on JDK 1.7, hence the problem. Could it be similar to you? – Cannes
@Pavanraodk Its not because that. – Tractate

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.

  1. To closed ideas,
  2. To remove all folder and file C:/Users/UserName/.m2/org/*,
  3. Open ideas and update Maven project,(right click on project -> maven->update maven project)
  4. After that update the project.
