Merry Christmas to you also Rajender.
The eaisest is to inject the DomainList domainList in you mailet
Just declare as field
@Resource(name = "dnsservice")
private DomainList domainList;
and the mailet container will inject it for you (see also [1] for an
example using a setter method).
That way, your mailet will benefit from any change in the domain list
code and from any change in the configuration (can be xml, jpa... based).
Thx, Eric

Hi Eric,
Merry Christmas to you :).
I am trying to read domains from the database from my custom matcher.
I have a written a helper class which is replica of
org.apache.james.domainlist.jpa.JPADomainList.java which has the below
method.
public List<String> getDomainListInternal() throws DomainListException {
List<String> domains = new ArrayList<String>();
EntityManager entityManager = entityManagerFactory
.createEntityManager();
LOGGER.info("entity manager created.......");
final EntityTransaction transaction =
entityManager.getTransaction();
try {
transaction.begin();
domains =
entityManager.createNamedQuery("listDomainNames")
.getResultList();
transaction.commit();
} catch (PersistenceException e) {
getLogger().error("Failed to list domains", e);
if (transaction.isActive()) {
transaction.rollback();
}
throw new DomainListException("Unable to retrieve
domains", e);
} finally {
entityManager.close();
}
if (domains.size() == 0) {
return null;
} else {
return new ArrayList<String>(domains);
}
Now In my custom mailet class, I have called the above method, but I
am unable to retrieve the domains from the database table. Below is my
code from custom mailtet.
try{
domainsList =
oTestJPADomainsList.getDomainListInternal();
}catch (Exception exp)
{
exp.printStackTrace();
}
if(domains != null && !domains.isEmpty()){
domains.clear();
}
if(domainsList != null && !domainsList.isEmpty()){
for(String aDomain : domainsList)
{
domains.add(aDomain);
}
} else {
LOGGER.error("Unable to read domains from JPA DOmains
List...");
throw new Exception("No Domains Found");
}
When I try to send an email I am getting throw the no domains found
exception (my custom exception).
Please can you guide in using the right api to read the domains from
the database source.
Regards,
Rajender
