The below code(not mine) is supposed to check the connection status of a zookeeper by using the znode_exists() method. I want to use it at a producerAPI before a message publish. But i am getting an error at defining the ZooKeeperConnection object. I have added the possible classes and libraries.
import java.io.IOException;
//import org.apache.zookeeper.*; adding this doesn't help
import org.apache.zookeeper.ZooKeeperMain;
import org.apache.zookeeper.KeeperException;
import org.apache.zookeeper.WatchedEvent;
import org.apache.zookeeper.Watcher;
import org.apache.zookeeper.Watcher.Event.KeeperState;
import org.apache.zookeeper.data.Stat;
public class ZKExists {
private static ZooKeeper zk;
private static ZooKeeperConnection conn; // Object cannot be resolve to a type
// Method to check existence of znode and its status, if znode is available.
public static Stat znode_exists(String path) throws
KeeperException,InterruptedException {
return zk.exists(path, true);
}
public static void main(String[] args) throws InterruptedException,KeeperException {
String path = "/Znode_path"; // Assign znode to the specified path
try {
ZooKeeperConnection conn = new ZooKeeperConnection();
zk = conn.connect("localhost");
Stat stat = znode_exists(path); // Stat checks the path of the znode
if(stat != null) {
System.out.println("Node exists and the node version is " +
stat.getVersion());
} else {
System.out.println("Node does not exists");
}
} catch(Exception e) {
System.out.println(e.getMessage()); // Catches error messages
}
}
}
Which library am i missing to make the object valid ?
I created in manager.conf a user manager named : mark , in "sip.conf" user named "utilisateur"
i want to call user : "utilisateur" via Asterisk-java , i tried this code :
import java.io.IOException;
import org.asteriskjava.manager.AuthenticationFailedException;
import org.asteriskjava.manager.ManagerConnection;
import org.asteriskjava.manager.ManagerConnectionFactory;
import org.asteriskjava.manager.TimeoutException;
import org.asteriskjava.manager.action.OriginateAction;
import org.asteriskjava.manager.response.ManagerResponse;
public class HelloManager
{
private ManagerConnection managerConnection;
public HelloManager() throws IOException
{
ManagerConnectionFactory factory = new ManagerConnectionFactory(
"localhost", "mark", "1234");
this.managerConnection = factory.createManagerConnection();
}
public void run() throws IOException, AuthenticationFailedException,
TimeoutException
{
OriginateAction originateAction;
ManagerResponse originateResponse;
originateAction = new OriginateAction();
originateAction.setChannel("SIP/utilisateur");
originateAction.setContext("default");
originateAction.setExten("2222");
originateAction.setPriority(new Integer(1));
originateAction.setTimeout(new Integer(30000));
// connect to Asterisk and log in
managerConnection.login();
// send the originate action and wait for a maximum of 30 seconds for Asterisk
// to send a reply
originateResponse = managerConnection.sendAction(originateAction, 30000);
// print out whether the originate succeeded or not
System.out.println(originateResponse.getResponse());
// and finally log off and disconnect
managerConnection.logoff();
}
public static void main(String[] args) throws Exception
{
HelloManager helloManager;
helloManager = new HelloManager();
helloManager.run();
}
}
And in extension.conf i added this extension :
[default]
exten => 2222,1,Dial(SIP/utilisateur)
exten => 2222,2,Answer
and i get this error fromasterisk server so could somone help me :
Exception in thread "main" org.asteriskjava.manager.TimeoutException: Timeout waiting for response to Originate

You're querying a URL that doesn't exist. Going to that URL returns "Not Found" which is what the exception is telling you. Use a valid URL and then see if your code works (there may be absolutely nothing wrong with your code).
Google BigQuery doesn't support ClientLogin auth. Where did you get that sample?
I'm trying to make a search through the Fedora Commons web service. I'm interested in the findObjects method. How can I make a search in Java equal to the example described on the findObjects syntax documentation.
I'm particularly interested in this type of request:
http://localhost:8080/fedora/search?terms=fedora&pid=true&title=true
I'll attach some code, I have a class that can call my Fedora service already.
package test.fedora;
import info.fedora.definitions._1._0.types.DatastreamDef;
import info.fedora.definitions._1._0.types.MIMETypedStream;
import java.io.ByteArrayInputStream;
import java.io.InputStream;
import java.util.List;
import javax.xml.ws.BindingProvider;
import org.w3c.dom.Document;
public class FedoraAccessor {
info.fedora.definitions._1._0.api.FedoraAPIAService service;
info.fedora.definitions._1._0.api.FedoraAPIA port;
final String username = "xxxx";
final String password = "yyyy";
public FedoraAClient() {
service = new info.fedora.definitions._1._0.api.FedoraAPIAService();
port = service.getFedoraAPIAServiceHTTPPort();
((BindingProvider) port.getRequestContext().put(BindingProvider.USERNAME_PROPERTY, username);
((BindingProvider) port).getRequestContext().put(BindingProvider.PASSWORD_PROPERTY, password);
}
public List findObjects() {
//how?
}
public List<DatastreamDef> listDatastreams(String pid, String asOfTime) {
List<DatastreamDef> result = null;
try {
result = port.listDatastreams(pid, asOfTime);
} catch (Exception ex) {
ex.printStackTrace();
}
return result;
}
}
It's easier using the client from mediashelf (http://mediashelf.github.com/fedora-client/). Here's an example searching for objects containing the string foobar in the title:
#Test
public void doTest() throws FedoraClientException {
connect();
FindObjectsResponse response = null;
response = findObjects().pid().title().query("title~foobar").execute(fedoraClient);
List<String> pids = response.getPids();
List<String> titles = new ArrayList<String>();
for (String pid : pids) {
titles.add(response.getObjectField(pid, "title").get(0));
}
assertEquals(7, titles.size());
}
This question already has answers here:
NullPointerException when setting attribute?
(5 answers)
Closed 7 years ago.
I have to make a litle change to an existing project(tomcat and java WebApplication).
now, in loginForm, if users type correct login and password, it is Ok,
to users wil be shown main page. But when any user types incorrect password,
or may be his account is temporarily locked, so to user again wil be shown loginform,
user can not know why he cannot log in, by what cause he can not login.
(for example "invalid username/password","user account locked",...).
now i want to insert the session error message that includes also causes of why user cannot log in.
insert(save) to session an attribute named "LoggingError".
i am writing as:
request.getSession().setAttribute("LoggingError", message);
but when running application, in this line
request.getSession().setAttribute("LoggingError", message);
occurs error in web page:
type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.

If your request object is a HttpServletRequest object then this should work.
If this isn't the problem can you send the exact code snippet (shouldn't need the whole program) and the exact error message?
this should work.
request.getSession(true).setAttribute("LoggingError", message);
Is your authentication provider specified as prototype scope bean? Not sure how Struts / WebWork is exactly integrated with Spring, but if your bean is singleton, it can not work.
In other words, make sure setServletRequest is called.
And by the way this application must be pretty old, if it has such package names as it has.
