How to run Spring 3.0 PetClinic in tomcat with Hibernate backed JPA

Question

OK, this probably is supposed to be the easiest thing in the world, but I\'ve been trying for the entire day, and it\'s still not working.. Any help is highly appreciated!

Answer 1

Ok, here is what I did:

1. Get Tomcat 6.0.26

2. Checkout the petclinic sample:

   svn co https://src.springframework.org/svn/spring-samples/petclinic/trunk/ petclinic
   

3. cd into the petclinic directory

4. Modify src/main/webapp/WEB-INF/spring/applicationContext-jpa.xml to use Hibernate:
   • COMMENT the <context:load-time-weaver> (load-time weaver SHOULD NOT be used with Hibernate, this is for Toplink)
   • Declare Hibernate as jpaVendorAdapter (comment the Toplink part, uncomment the Hibernate part)
5. Modify the src/main/webapp/WEB-INF/web.xml to use the applicationContext-jpa.xml

6. Modify the pom.xml to bundle jta.jar in the war (as pointed out by @skaffman):

   <dependency>
     <groupId>javax.transaction</groupId>
     <artifactId>com.springsource.javax.transaction</artifactId>
     <version>1.1.0</version>
     <!--scope>test</scope-->
   </dependency>
   

7. Build the war

   mvn install
   

8. Deploy it to Tomcat

   cp target/petclinic.war $TOMCAT_HOME/webapps
   

9. Browse

   http://localhost:8080/petclinic
   

Answer 2

Looks like a problem with PetClinic packaging:

and

http://jira.springframework.org/browse/SPR-6880

There's fix in there for the pom.xml
