I have a class IntLdap in which I have the following code:
Hashtable env = new Hashtable();
env.put(Context.PROVIDER_URL, SERVER);
env.put(Context.INITIAL_CONTEXT_FACTORY, FACTORY);
ctx = new InitialDirContext(env);
The public static variable SERVER contains the URL and PORT of
our LDAP-server; the public static variable FACTORY equals
"com.sun.jndi.ldap.LdapCtxFactory"
When I use this class in a console application, everything
works fine. THERE ARE NO ERROR IN THE CLASS IntLdap!
When I use the same class in a Servlet, I get the following
exception:
[Root exception is java.lang.ClassNotFoundException:
com.sun.jndi.ldap.LdapCtxFactory]javax.naming.NoInitialContextException:

Remark1: the classpath of JSERV is the same as
the classpath I use to run my console application
Remark2: just to be sure I set all the permission of
the jndi/ldap/providerutil classes to 777.
Why doesn't this work???
