I am facing the following error when I try to create bean using Application Context for the circle class! Circle class implements the Shape
interface which contains a method draw()
.
Configuration:
I am learning spring and have setup a Java Project in eclipse with all the required jars (Spring and Apache commons logging). I have the spring.xml in my classpath in the src folder. Have also tried downloading the latest jars (Spring 4.0.4 release, previously worked with 4.0.0) but now is not working. Cannot think of any solution to fix this.
Error:

The problem occurs because
PropertyEditorRegistrySupport.class.getClassLoader()
is null
. According to JavaDoc, this happens if the class PropertyEditorRegistrySupport
has been loaded by the bootstrap class loader instead of the system class loader:
Some implementations may use null to represent the bootstrap class loader. This method will return null in such implementations if this class was loaded by the bootstrap class loader.
Perhaps your Spring libraries are on the endorsed class path?
