Zugriff auf Third Party Klassen im Beanshell Skript

Author: dheim

Hallo zusammen,

ich versuche Testweise in einem Beanshell-Skript auf eine Klasse (CoreContextFactory) zuzugreifen die in einem jar liegt, welche als lib in einer Library-Komponente auf dem Server installiert ist.

// LDAP-Connection
Hashtable env = new Hashtable(6);
env.put(Context.INITIAL_CONTEXT_FACTORY, "org.apache.directory.server.core.jndi.CoreContextFactory");
env.put(Context.PROVIDER_URL, "ldap://localhost:10389");
env.put(Context.SECURITY_AUTHENTICATION, "simple");
env.put(Context.SECURITY_PRINCIPAL, "cn=system administrator");
env.put(Context.SECURITY_CREDENTIALS, "admin");
DirContext ldap = new InitialDirContext(env);

dabei kommt es in der letzten Zeile zu einer ClassNotFoundException weil er die Factory-Klasse nicht findet. Habe ich eine falsche Vorstellung davon wie auf eine Library vom BeanShell-Skript aus zugegriffen werden kann?

Bin Dankbar für jeden Tipp,

Viele Grüße

Dominik
