Db access from IdM extension framework

Question

Hi Sappers
I've been looking into this extension framework for IdM 7.1 where you can do some validation on onSubmit events.
In my case i would like to make some searches in the idm database to check some constraints on the entry but the only way I could find was through the EntryFactory but here I need to know the exact mskey for the entries I want to use and that is not good enough!
So my questions is there another way to interact with the idm database (I would like to execute select queries or at least execute some searches on various entry values)?

Jesper:
Firstly, I was officially told that it is not recommended to do SQL lookups in the Extension Framework because it has a negative impact on performance.
Aside from that disclaimer, if you import the java.sql.* and javax.sql.DataSource packages, you can use your existing database connection that is set up on your AS Java system to connect to the database and execute queries. Here is a snippet of what we use as an example, in this case matchQuery is defined elsewhere:
Properties props = new Properties();
props.put(Context.INITIAL_CONTEXT_FACTORY,"com.sap.engine.services.jndi.InitialContextFactoryImpl");
Context idmCont = null;
DataSource idmDS = null;
try
idmCont = new InitialContext(props);
idmDS = (DataSource) idmCont.lookup("jdbc/IDM_DataSource");
catch (NamingException ne)
e1 = ne.getMessage();
//execute the query for matching
try
Connection idmConn = idmDS.getConnection();
Statement idmState = idmConn.createStatement();
ResultSet idmMatch = idmState.executeQuery(matchQuery);
idmMatch.next();
matchedMSKEY = idmMatch.getLong(1);
catch (SQLException se)
e2 = se.getMessage();
This may not be the most effecient way of doing things, but it will at least point you in the correct direction with regards to the classes and packages you would need.
