java.lang.ClassNotFoundException: org.apache.commons.dbcp2.datasources

Question

I have added the necessary jars for the project but still i get the following mentioned exception. I am confused whether this is because of spring-mvc or commons.dbcp2. Can someone help me out to solve with explanation

Error in my console

Answer 1

According to the maven site commons-dbcp2-2.1.jar depends on:

commons-logging » commons-logging   1.2
junit » junit   4.11
org.apache.commons » commons-pool2  2.3
org.apache.geronimo.modules » geronimo-transaction  1.2-beta
org.apache.geronimo.specs » geronimo-jta_1.1_spec   1.1.1
tomcat » naming-common  5.0.28
tomcat » naming-java

See: DBCP2-Maven

So you also need this jars. The class you need for this exception in particular is in commons-pool2 , I think. If you start using Maven or Gradle you will avoid issues with dependencies like this. Here is a good tutorial for Spring with Maven: The tutorial

Answer 2

For me, the issue was that my local m2 cache of the JAR file was corrupt. After I deleted it, Maven said it could not download 2.1.1. I switched to 2.5.0 and the app loaded successfully.
