Answer 1

For this error, there can be different solutions. I have noted down the ones that had worked for me.

Solution 1. This is always happened in deployment and debugging environment. In deployment environment, just make sure your server classpath has included the Spring jar library (e.g spring-4.0.4.jar).

In debugging environment, the steps may vary from different IDE, but the solution is same. In Eclipse, developers usually will create a tomcat, jboss…whatever application server for debugging, just make sure the correct Spring jars are included.

1. Double click on your debugging server
2. Click on the “Open launch configuration” to access the server environment
3. Click on the classpath tab
4. Include the Spring jar file here , it may also required common log jar due to Spring dependency.
5. Done, run your application again.

.

Solution 2. If you are using Maven as a build tool and downloading dependencies using it, there can be some jar conflict. Because Tomcat servers normally provide some jars such as servlet-api and jpa-api. So if you again included them using maven; there will be problems in identifying them.

Solution 3. If you are using Eclipse as your IDE and using Maven as your build tool and tomcat as your server; remember Tomcat server will not look on the jars which are just inside the folders. For that there's a small trick,

1. Right click on your project and select properties
2. From the displayed window, select Deployment Assembly
3. Select Add
4. Add Maven dependencies
5. Click Apply and Click OK

Hope one of these solutions would help you to solve your problem. Happy Coding and make sure that is using Java.

Answer 2

In my situation, I use maven to build the project, just because the war file is not created correctly, it will leads to this exception. I check the war file and run install again, that solve my problem.
