javax.persistence jar missing

[abking]

Below is my pom.xml and within it I have spring-orm (3.0.2.RELEASE) as a dependency. I thought that as a result of having spring-orm as a dependency, javax.persistence would automatically be downloaded to my local m2 respository. Anyone know why this DIDN'T happen? And how I can cause maven to automatically download javax.persistence with the other transient dependencies?

<project>
        <!-- Spring Framework Dependencies -->
	<dependency>
		<groupId>org.springframework</groupId>
		<artifactId>spring-core</artifactId>
		<version>${spring.version}</version>
	</dependency>
	<dependency>
		<groupId>org.springframework</groupId>
		<artifactId>spring-orm</artifactId>
		<version>${spring.version}</version>
	</dependency>
  </dependencies>
</project>

Hi

In fact there is dependency on javax.persistence, but it's optional:

		<dependency>
			<groupId>javax.persistence</groupId>
			<artifactId>persistence-api</artifactId>
			<version>1.0</version>
			<optional>true</optional>
		</dependency>

The reason is that you can use spring-orm with e.g. plain Hibernate or iBatis - in such case you really do not depend on JPA.

Just add this dependency to your POM with a dependency to JPA implementation of your choice (e.g. Hibernate).
