[jboss-user] [JCA/JBoss] - Re: How to connect my EJB to Firebird database?
Now the code in servlet works. I wrote in servlet init method
| InitialContext context = new InitialContext();
| DataSource ds = (DataSource)context.lookup("java:/FIrebirdDS");
| Connection con = ds.getConnection();
| Statement st=con.createStatement();
| ResultSet rs=st.executeQuery("select * from person");
|
Everything works fine, there are proper data in ResultSet after executing st.executeQuery
method. So, FIrebirdDS works. But the old problem stays. In the same servlet init method I
try to use my EJB:
| Object ref = context.lookup("ejb/Person");
| home = (Person) ref;
|
Again, it works, I can then execute the business method of my PersonBean. But when inside
PersonBean EJB I uncomment the line
//@PersistenceContext EntityManager em;
I get an exception
