Hi
Usually this exception "javax.naming.NameNotFoundException: Name java:comp
is not bound in this Context" occurs in Tomcat when you have the same jar files
in WEB-INF/lib and Tomcat's Common/lib folder. This is the problem I faced
long back when I was using tomcat and got resolved as soon as I removed those
conflicting jars from my webapp. you can try the same. Hopefully this will help.
Thanks
Sandhya

Hi
when I try to do this programmatically like this
Context initCtx = null;
Context envCtx;
DataSource ds = null;
try {
initCtx = new InitialContext();
// envCtx = (Context) initCtx.lookup("java:/comp/env");
ds = (DataSource)
initCtx.lookup("java:comp/env/jdbc/workflowdb");
} catch (NamingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
propMap.put("openjpa.ConnectionFactory", ds);
propMap.put("openjpa.ConnectionFactoryMode",
"managed");
propMap.put("openjpa.FlushBeforeQueries", "false");
EntityManagerFactory emf = Persistence.createEntityManagerFactory(
"MyOpenJPa", propMap);
I always get
javax.naming.NameNotFoundException: Name java:comp is not bound in this
Context
So I guess this is related, but followed the tomcat doc so I can't
understand why this does not work.
