Hi there, I am trying to create a database index for a mapping table. My source looks like this: | @ManyToMany( | targetEntity=PortalUser.class, | cascade = { CascadeType.PERSIST, CascadeType.MERGE }, | fetch = FetchType.LAZY | ) | @JoinTable( | name="friends", | joinColumns={@JoinColumn(name="psid")}, | inverseJoinColumns={@JoinColumn(name="ptid")}, | uniqueConstraints={@UniqueConstraint(columnNames={"psid", "ptid"})} | ) | If I try to use the following code i get an error: | @ManyToMany( | targetEntity=PortalUser.class, | cascade = { CascadeType.PERSIST, CascadeType.MERGE }, | fetch = FetchType.LAZY | ) | @JoinTable( | name="friends", | joinColumns={@JoinColumn(name="psid")}, | inverseJoinColumns={@JoinColumn(name="ptid")}, | uniqueConstraints={@UniqueConstraint(columnNames={"psid", "ptid"})} | ) | @Index(name = "friendindex", columnNames={"psid", "ptid"}) | Does any one has a solution for this? Thank you very much, Maciej View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3988511#...
