Hi all,
I am trying to implement the following example (Implementing Spring-based
DAOs without callbacks), as here:
https://springmodules.dev.java.net/docs/reference/0.3/html_single/#d0e1669
https://springmodules.dev.java.net/docs/reference/0.3/html_single/#d0e1669
Within my DAO (which extends JackrabbitDAOSupport, which itself extends
JcrDaoSupport), getSession(true) is throwing the following exception:
java.lang.IllegalArgumentException: No sessionFactory specified.
Here is my code:
ProviderDAOImpl:
public class ProviderDAOImpl extends JackrabbitDAOSupport
{
private static org.apache.log4j.Logger _lLogger =
org.apache.log4j.Logger.getLogger(ProviderDAOImpl.class);
public ProviderDAOImpl()
{
super();
}
public ArrayList<ProviderBean> listProviders()
{
Session jcrSession = getSession(true);
ArrayList<ProviderBean> providers = new
ArrayList<ProviderBean>();
try
{
Workspace ws = jcrSession.getWorkspace();
QueryManager qm = ws.getQueryManager();
// Specify a query using the XPATH query language
Query q =
qm.createQuery("//provid...@isdeleted!='true']", Query.XPATH);
QueryResult res = q.execute();
// Obtain a node iterator
NodeIterator provs = res.getNodes();
_lLogger.debug(provs.getSize());
while (provs.hasNext())
{
Node providerNode = provs.nextNode();
providers.add(new
ProviderBean(providerNode.getUUID(),
providerNode.getProperty("name").getString(),
providerNode.getProperty("GUID")
.getString(),
providerNode.getProperty("isDeleted").getBoolean()));
}
} catch (Exception e)
{
_lLogger.fatal(e.getCause(), e);
} finally
{
}
return providers;
}
}

JackrabbitDAOSupport:
public class JackrabbitDAOSupport extends JcrDaoSupport
{
JcrSessionFactory sessionFactory;
JcrTemplate template;
public JackrabbitDAOSupport()
{
}
}

-------------------------------------
I understand that I may need to inject the jcrTemplate into my DAO (as
getSession() eventually calls template.getSessionFactory(), and in the
debugger template == null).
Please could someone help me out? I've tried with and without using the
JackrabbitDAOSupport class (i.e. in the spring config file). I've read over
and over the tutorial example but it seems that some information is missing
(or more likely I am doing something daft). Running through the debugger I
can see that the initial call to JcrDaoSupport's setSessionFactory() is
correctly instantiating the member template.
Thanks in advance for any help.
