[it_kumarnitin]

Hi....

I dont hav any idea how to execute extended operations in spring ldap.First i was using netscape ldap connection and i am able to execute extended operation using ldapconnection...Plz reply... I am giving a snippet of code using netscape ldap connection for extended operation...its working So plz tel me how can i execute extended op in spring ldap..

LDAPConnection ldapTemplate;
LdapExecuteArgument executeArgs = new LdapExecuteArgument(objectId,methodID,parameters);
byte[] vals = new byte[]{};
vals = executeArgs.constructBytes(executeArgs.constructBE R());

LDAPExtendedOperation exop = null;
String OID = "0.0.17.1218.127.127.10";
exop = new LDAPExtendedOperation(OID, vals );
LDAPExtendedOperation exres = null;
exres = ldapTemplate.extendedOperation( exop );//no such method in spring ldaptemplate
LdapExecuteResult res = new LdapExecuteResult(exres.getValue());

Extended operations is supported by JNDI. However, we have no explicit support for the extendedOperation method in LdapTemplate. Chapter 5 in the Spring LDAP reference manual describes how to add missing API methods.

Perhaps you could try something like this:

   MyExtendedResponse response = (MyExtendedResponse) ldapTemplate.executeReadOnly(new ContextExecutor() {
      public Object executeWithContext(DirContext ctx)
            throws javax.naming.NamingException {
         if (!(ctx instanceof LdapContext)) {
            throw new IllegalArgumentException(
               "Extended operations require LDAPv3 - "
               + "Context must be of type LdapContext");
         }
         LdapContext ldapContext = (LdapContext) ctx;
         return ldapContext.extendedOperation(new MyExtendedRequest());
      }
   });

You must write your own implementations of the ExtendedRequest/ExtendedResponse interfaces:

   private static class MyExtendedRequest implements ExtendedRequest {
      ...
      public ExtendedResponse createExtendedResponse(String id, byte[] berValue, int offset, int length)
            throws NamingException {
         return new MyExtendedResponse(id, berValue, offset, length);
      }
   }

   private static class MyExtendedResponse implements ExtendedResponse {
      MyExtendedResponse(String id, byte[] berValue, int offset, int length)
            throws NamingException { ... }
      ...
   }
