Hello,

i am trying to connect our Active Directory to retrieve some user Information. When trying to get an InitialLdapContext i get the following exception:

javax.naming.NoInitialContextException: Cannot instantiate class: com.sun.jndi.ldap.LdapCtxFactory [Root exception is java.lang.ClassNotFoundException: com.sun.jndi.ldap.LdapCtxFactory]

The code Looks as follows:

private LdapContext getInitialContext() throws NamingException {

Hashtable<String,String> env = new Hashtable<String,String>();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.SECURITY_AUTHENTICATION, "simple");
env.put(Context.SECURITY_PRINCIPAL, ADMIN_NAME);
env.put(Context.SECURITY_CREDENTIALS, ADMIN_PASSWORD);
env.put(Context.PROVIDER_URL, "ldap://" + HOST + ":" + PORT);

return new InitialLdapContext(env, null);
}

Has anyone an idea why the factory class cannot be found? I am using CQ5.5.

Btw, when i execute the same code outside of CQ5 on my Windows command line (CLASSPATH=.) the code works fine.

Best Regards

Jan

This looks related to the workaround that is documented when worknig with with web services.

Solution:
To fix this issue and ensure that you can create a bundle that consumes web services as described in this article, modify the sling.properties file located in the crx-quickstart\conf folder. Add the following line of code to this file: sling.bootdelegation.com.sun=com.sun.*. Then restart the server using the JCR file. Once you perform this task, you can follow along with this article.

Hello Steve,

thanks for your reply. I tried this, added the line "sling.bootdelegation.com.sun=com.sun.*" to the sling.properties file and restarted the CQ5.5 instance. The problem is still the same :-(.

Any other suggestions?

Best Regards

Jan
