jUnit Notes

1. java.lang.NoSuchMethodError: org.springframework.beans.BeanUtils.instantiateClass

Solution:  http://stackoverflow.com/questions/8237181/spring-junit-test-error

Background: struts-spring-plugin 2.3.7 depends on Spring 3.0.5 transitively, we need to explicitly add Spring 3.1.x dependencies.

<dependency>
			<groupId>org.apache.struts</groupId>
			<artifactId>struts2-spring-plugin</artifactId>
			<version>${struts2.version}</version>
		</dependency>
		
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-beans</artifactId>

		</dependency>

2. java.io.FileNotFoundException: class path resource [classpath:META-INF/persistence.xml] cannot be opened because it does not exist

Caused by redundant spaces, as shown below:

<property name="persistenceXmlLocation">
			<value>
				classpath*:META-INF/persistence.xml
			</value>
		</property>

Correted it as below:

<property name="persistenceXmlLocation">
			<value>classpath*:META-INF/persistence.xml</value>
		</property>
