How to reset the OIM password without using the Identity Manager UI

Typically the ODSM (Oracle Directory Services Manager) allows the user to change the passwords using the url http://hostname:7005/odsm . There are situations where one needs to change the password via a Java Web Service. This Post uses the OID (Oracle Internet Directory) Java API to reset password information. import java.io.InputStream; import java.util.Hashtable; import java.util.Properties; import javax.naming.Context; import javax.naming.NamingException; import javax.naming.directory.InitialDirContext; import javax.naming.ldap.InitialLdapContext; import oracle.ldap.util.AuthFailureException; import oracle.ldap.util.LDIF; import oracle.ldap.util.ModPropertySet; import oracle.ldap.util.RootOracleContext; import oracle.ldap.util.User; import oracle.ldap.util.Util; import oracle.ldap.util.UtilException; import oracle.ldap.util.Subscriber; public class OIDAuthenticate implements OIDConstants {     public OIDAuthenticate() {         super();     }            public String oidResetPassword(String userId,                String password) throws OIDException {         InitialDirContext ctx = null;         try {             ctx = getOIDConnection();             RootOracleContext roc = null;             Subscriber sub = null;             User user = null;             roc = new RootOracleContext(ctx);             try {                 sub = roc.getSubscriber(ctx,util.IDTYPE_DEFAULT,                        null, new String[] { "*" });             } catch (UtilException ue) {                 OIDException le =                     new OIDException(ue.getLDAPErrorCode() + "",                      ue.getMessage());                 le.printStackTrace();             }            try {                 user =                  sub.getUser(ctx, Util.IDTYPE_SIMPLE,                   userId, new String[] { "*" });             } catch (UtilException e) {                 OIDException le =                     new OIDException(e.getLDAPErrorCode() + "",                      e.getMessage());                 le.printStackTrace();             }             ModPropertySet mps = new ModPropertySet();             mps.addProperty(LDIF.ATTRIBUTE_CHANGE_TYPE_REPLACE,                  "userpassword",password);             user.setProperties(ctx, mps);             return STR_SUCCESS;         } catch (Exception e) {             System.out.println("Problem resetting password: ");             e.printStackTrace();             return "EXCEPTION_OCCURED";         }finally         {              try {               if(ctx!=null) ctx.close();           } catch (NamingException ue) {               throw new OIDException("ERR", ue.getMessage());           }         }      }     public InitialDirContext getOIDConnection() throws OIDException{         InitialDirContext ctx;         try {             Hashtable env = new Hashtable();             env.put(Context.INITIAL_CONTEXT_FACTORY,                     "com.sun.jndi.ldap.LdapCtxFactory");             env.put(Context.SECURITY_AUTHENTICATION, "simple");             env.put(Context.SECURITY_PRINCIPAL, "cn=orcladmin");             env.put(Context.SECURITY_CREDENTIALS, "password1");             env.put(Context.PROVIDER_URL,                                                       "ldap://hostname:3060/");             env.put(Context.REFERRAL, "follow");             ctx = new InitialLdapContext(env, null);             return ctx;         } catch (NamingException ne) {             throw new OIDException("EXCEPTION_!",                                      ne.getMessage());           }     } }
