Then you can use SearchService and query by using "PATH" from Lucene syntax.

You can use getChildByName function

NodeService (Alfresco 5.2-SNAPSHOT API)

Here's a runnable class that leverages OpenCMIS to check for the presence of a folder with a given name.

package com.someco.cmis.examples;

import java.util.HashMap;
import java.util.List;
import java.util.Map;

import org.apache.chemistry.opencmis.client.api.ItemIterable;
import org.apache.chemistry.opencmis.client.api.QueryResult;
import org.apache.chemistry.opencmis.client.api.Repository;
import org.apache.chemistry.opencmis.client.api.Session;
import org.apache.chemistry.opencmis.client.api.SessionFactory;
import org.apache.chemistry.opencmis.client.runtime.SessionFactoryImpl;
import org.apache.chemistry.opencmis.commons.SessionParameter;
import org.apache.chemistry.opencmis.commons.enums.BindingType;

public class FolderChecker {
     private String serviceUrl = "http://localhost:8080/alfresco/api/-default-/public/cmis/versions/1.1/browser";
    private Session session = null;

    public static void main(String[] args) {
         if (args.length != 1) {
              System.out.println("USAGE: java FolderChecker [folder name]");
              System.exit(-1);
         }
         FolderChecker fc = new FolderChecker();
         System.out.println("Does folder: " + args[0] + " exist? " + fc.doesFolderExist(args[0]));
    }
    
    public boolean doesFolderExist(String folderName) {
          String queryString = "select cmis:objectId from cmis:folder where cmis:name = '" + folderName + "'";
         ItemIterable<QueryResult> results = getSession().query(queryString, false);
         if (results.getTotalNumItems() > 0) {
              return true;
         } else {
              return false;
         }
    }
    
     public Session getSession() {

          if (session == null) {
               // default factory implementation
               SessionFactory factory = SessionFactoryImpl.newInstance();
               Map<String, String> parameter = new HashMap<String, String>();
     
               // user credentials
               parameter.put(SessionParameter.USER, "admin"); // <-- Replace
               parameter.put(SessionParameter.PASSWORD, "admin"); // <-- Replace
     
               // connection settings
               parameter.put(SessionParameter.BROWSER_URL, this.serviceUrl); // Uncomment for Atom Pub binding
               parameter.put(SessionParameter.BINDING_TYPE, BindingType.BROWSER.value()); // Uncomment for Atom Pub binding

               List<Repository> repositories = factory.getRepositories(parameter);
     
               this.session = repositories.get(0).createSession();
          }
          return this.session;
     }
}
