In Eclipse, in JPA Project (runs in Java SE), Properties->Javadoc location, I attached the JavaDoc at path

/usr/share/javadoc/java-1.7.0-openjdk-1.7.0.60-2.4.3.0.fc19/api/

The documentation for Java works but if I pass the mouse pointer over some JPA functions (ex. getTransaction().begin() ) I obtain the error message:

void javax.persistence.EntityTransaction.begin()

Note: This element neither has attached source nor attached Javadoc and hence no Javadoc could be found.

How can I fix this problem?

You can use the online link: https://docs.oracle.com/javaee/7/api/

Or download the zip file: http://download.oracle.com/otndocs/jcp/j2ee-1.4-fr-doc-oth-JSpec/

Or if you are using Maven, you can enable "Download Artifact JavaDoc" on its Preferences page.
