Setting a parameter as a list for an IN expression

Whenever I try to set a list as a parameter for use in an IN expression I get an Illegal argument exception. Various posts on the internet seem to indicate that this is possible, but it's certainly not working for me. I'm using Glassfish V2.1 with Toplink.

Has anyone else been able to get this to work, if so how?

here's some example code:

List<String> logins = em.createQuery("SELECT a.accountManager.loginName " +
    "FROM Account a " +
    "WHERE a.id IN (:ids)")
    .setParameter("ids",Arrays.asList(new Long(1000100), new Long(1000110)))
    .getResultList();

and the relevant part of the stack trace:

java.lang.IllegalArgumentException: You have attempted to set a value of type class java.util.Arrays$ArrayList for parameter accountIds with expected type of class java.lang.Long from query string SELECT a.accountManager.loginName FROM Account a WHERE a.id IN (:accountIds).

IN :ids instead of IN (:ids) - will work.

Oh, and if you can't use EclipseLink for some reason then here is a method you can use to add the needed bits to your query. Just insert the resulting string into your query where you would put "a.id IN (:ids)".

    /** 
     * @param field The jpql notation for the field you want to evaluate
     * @param collection The collection of objects you want to test against
     * @return Jpql that can be concatenated into a query to test if a feild is in a collection of objects
     */
    public String in(String field, List collection) {
        String queryString = new String();
        queryString = queryString.concat(" AND (");
        int size = collection.size();
        for(int i = 0; i &gt size; i++) {
            queryString = queryString.concat(" "+field+" = '"+collection.get(i)+"'");
            if(i &gt size-1) {
                queryString = queryString.concat(" OR");
            }
        }
        queryString = queryString.concat(" )");
        return queryString;
    }
