Tomcat 7 SEVERE: Context [] startup failed due to previous errors after add spring-data-jpa to dependency in pom
I have a spring rest app.It is configured with annotations.
When I add spring-data-jpa dependency the application is falling with error on Tomcat 7(jdk 1.7):
Jun 22, 2015 5:05:18 PM org.apache.catalina.startup.HostConfig deployWAR
INFO: Deploying web application archive /var/lib/tomcat7/webapps/springRest-1.1.war
Jun 22, 2015 5:05:19 PM org.apache.catalina.core.StandardContext startInternal
SEVERE: Context [/springRest-1.1] startup failed due to previous errors

I add logging.properties file to WEB-INF/classes:
org.apache.catalina.core.ContainerBase.[Catalina].level = INFO
org.apache.catalina.core.ContainerBase.[Catalina].handlers = java.util.logging.ConsoleHandler

But I didn't catch any additional info into log.
My source code:
MyWebApplicationInitializer.java:
import upc.ua.springrest.config.WebConfiguration;
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

public class MyWebApplicationInitializer extends  AbstractAnnotationConfigDispatcherServletInitializer {

protected Class<?>[] getRootConfigClasses() {
    return null;
}

protected Class<?>[] getServletConfigClasses() {
    return new Class[]{WebConfiguration.class};
}

protected String[] getServletMappings() {
    return new String[]{"/"};
}

}
WebConfiguration.java:
package upc.ua.springrest.config;

import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "upc.ua.springrest")
public class WebConfiguration extends WebMvcConfigurerAdapter {


}

HelloWorldController.java:
package upc.ua.springrest.controller;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class HelloWorldController {

    @RequestMapping("/helloWorld")
    public String helloWorld() {
        return "dataSource.toString()";
    }

    @RequestMapping("/")
    public String root() {
        return "Hello, Alex!";
    }
}

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>2.3.2</version>
            <configuration>
                <source>1.7</source>
                <target>1.7</target>
                <compilerArguments>
                    <endorseddirs>${endorsed.dir}</endorseddirs>
                </compilerArguments>
            </configuration>
        </plugin>
