To resolved your problem you need to add some jar file in your project.
antlr-2.7.7.jar
commons-lang3-3.1.jar
commons-logging-1.1.3.jar
dom4j-1.6.1.jar
hibernate-commons-annotations-4.0.1.Final.jar
hibernate-core-4.2.0.Final.jar
hibernate-jpa-2.0-api-1.0.1.Final.jar
javassist-3.15.0-GA.jar
jboss-logging-3.1.0.GA.jar
jboss-transaction-api_1.1_spec-1.0.0.Final.jar
commons-lang3-3.1.jar
commons-logging-1.1.3.jar
dom4j-1.6.1.jar

Note: If possible then add the latest versions of above jar files.
You also need add log4j.properties parallel to the src file.
# Set root logger level to DEBUG and its only appender to A1.
log4j.rootLogger=DEBUG, A1
# A1 is set to be a ConsoleAppender.
log4j.appender.A1=org.apache.log4j.ConsoleAppender
# A1 uses PatternLayout.
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n**strong text**
