Grünschnabel
Guten Morgen!

Ich benutze für meine Wicket-Webanwendung Spring, Hibernate und JPA. Wenn ich das war-File deploye wird jedoch folgende Fehlermeldung in den Logfiles von Tomcat angezeigt:

Code: 
ERROR org.springframework.web.context.ContextLoader - Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [spring-jpa.xml]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: No persistence unit with name 'TestUnit' found

Ich wäre seh dankbar, wenn ihr mir einen Hinweis geben könntet, was ich falsch gemacht habe. Gegoogelt habe ich schon, jedoch bisher nichts brauchbares gefunden :-(

Hi,
erstelle eine META-INF/persistence.xml im Source Verzeichnis und lege die Persistence Unit dort an:

XML: 
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0"
	xmlns="http://java.sun.com/xml/ns/persistence"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
	
  <persistence-unit name="TestUnit">
     <class>com.test.Demo</class>
  </persistence-unit>

</persistence>
