I have the following EJB implementing a simple ActiveMQ message enqueue. The ActiveMQ code itself works just fine. This is being deployed on a TomEE server.
SenderBean class:
package Beans;
import javax.ejb.LocalBean;
import javax.ejb.Stateless;
import javax.jms.Connection;
import javax.jms.ConnectionFactory;
import javax.jms.Destination;
import javax.jms.JMSException;
import javax.jms.MessageProducer;
import javax.jms.Session;
import javax.jms.TextMessage;
import org.apache.activemq.ActiveMQConnection;
import org.apache.activemq.ActiveMQConnectionFactory;
#LocalBean
#Stateless
public class SenderBean {
private ConnectionFactory factory = null;
private Connection connection = null;
private Session session = null;
private Destination destination = null;
private MessageProducer producer = null;
public SenderBean() {
}
public void sendMessage() {
try {
factory = new ActiveMQConnectionFactory(
ActiveMQConnection.DEFAULT_BROKER_URL);
connection = factory.createConnection();
connection.start();
session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
destination = session.createQueue("SAMPLEQUEUE");
producer = session.createProducer(destination);
TextMessage message = session.createTextMessage();
message.setText("Hello ...This is a sample message..sending from FirstClient");
producer.send(message);
System.out.println("Sent: " + message.getText());
connection.close();
} catch (JMSException e) {
e.printStackTrace();
}
}
}
I also have the following class which tries to use the bean in a servlet. If I include the #EJB annotation, like in the following example, the servlet throws an exception upon receiving post. However, if i remove the annotation and instantiate the bean class with new SenderBean(), everything works as it should. What could be the cause of this?
SenderServlet class:
package Servlets;
import Beans.ReceiverBean;
import Beans.SenderBean;
import javax.ejb.EJB;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
#WebServlet(name = "SenderServlet")
public class SenderServlet extends HttpServlet {
#EJB
SenderBean senderBean;
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
senderBean.sendMessage();
}
}
The exception being received in the HttpServletResponse after a 500 error:
HTTP Status 500 - Error instantiating servlet class Servlets.SenderServlet</h1><div class="line"></div><p><b>type</b> Exception report</p><p><b>message</b> <u>Error instantiating servlet class Servlets.SenderServlet</u></p><p><b>description</b> <u>The server encountered an internal error that prevented it from fulfilling this request.</u></p><p><b>exception</b></p><pre>javax.servlet.ServletException: Error instantiating servlet class Servlets.SenderServlet

don't you have a classpath clash with activemq or hibernate? are the provided library NOT in WEB-INF/lib?

I'm beginner please help me!
I'm glad that you joined stack overflow. This error has nothing to do with your Java code. The error code says:
java.sql.SQLException: Cannot create PoolableConnectionFactory (Public Key Retrieval is not allowed)
All you need to do is set up a username and password to connect to your database.
I've a .mdb access file and I'm indexing the datas to my solr core. I wrote this java class to index them in solr core. When I'm running this java class as java application, it works fine but when I'm running server side it's not working.

You have to move the Driver in the JRE/lib/ext
I have run into a problem that I have been trying to figure out for days:
I added my driver: mysql-connector-java-5.1.40.jar to build path.
web-inf lib folder, apache tomcat lib folder. And also I have it in web app libaries.
However when I just run a main class and run it works, it is something to do with the web app?
This is my code:
This is the servlet class, that I use to connect to my database
package sql;
import java.io.IOException;
import java.sql.SQLException;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
/**
* Servlet implementation class RegisterServlet
*/
#WebServlet("/register")
public class RegisterServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
private DbUtil sql = new DbUtil();
/**
* #see HttpServlet#HttpServlet()
*/
public RegisterServlet() {
super();
// TODO Auto-generated constructor stub
}
/**
* #see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
*/
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String email = request.getParameter("email");
String username = request.getParameter("username");
String password = request.getParameter("password");
if (sql.addToAccountToDatabase(username, password, email)) {
System.out.println("Gongratz");
} else {
System.out.println("mhhh ?");
}
}
/**
* #see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
*/
}
this is the second class how i make connection
package sql;
import java.sql.*;
public class DbUtil {
public Connection getConnection() {
Connection connect = null;
try {
String url = "jdbc:mysql://hidden:3306/hidden";
connect = DriverManager.getConnection(url, "hidden", "hidden");
return connect;
} catch (Exception e) {
System.out.println("Cannot connect to database");
e.printStackTrace();
}
return connect;
}
public boolean addToAccountToDatabase(String username, String password, String email) {
try {
String query = "INSERT INTO Account (username, password, email) VALUES (?, ?,?)";
PreparedStatement pStat = getConnection().prepareStatement(query);
pStat.setString(1, username);
pStat.setString(2, password);
pStat.setString(3, email);
pStat.executeUpdate();
return true;
} catch (Exception e) {
System.out.println("User already exists");
e.printStackTrace();
return false;
}
}
}
And I get this error:
Cannot connect to database

mhhh ?
Because the String "jdbc:mysql" doesn't declare the driver Class itself, but only the name registered by a potential driver. You have to force the JVM to load the Driver class with a :
Class.forName("com.mysql.jdbc.Driver").newInstance();
before starting the JDBC connection.
You need 3 steps to solve your problem:
Add this code before connection Class.forName("com.mysql.jdbc.Driver");
Add 'JConnector.jar' into your project and build path.
Don't try enter same person because there is error in stack trace "User all ready exist ".
Adding the JAR file into your CLASSPATH (for compilation needs) / project's BUILDPATH and also under your project's WEB-INF/lib folder (for runtime references, i.e., when you deploy your application to an application server). For further reference, please go through this link
Class.forName("com.mysql.jdbc.Driver");
This is no longer required as per Official Java documentation here, but it is a mandatory step if you are using prior versions of JDBC 4.0.
This question can provide you lot many details on this regards.
Hope all these details help you resolve your issue!
I'm trying to get Spring 3.2.3 project with PrimeFaces 3.5 to work on Tomcat 7.0.42, but I'm stuck on this error:

Here's my WebApplicationInitializer:
import javax.faces.webapp.FacesServlet;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.ServletRegistration;
import org.springframework.web.WebApplicationInitializer;
import org.springframework.web.context.ContextLoaderListener;
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;
public class Initializer implements WebApplicationInitializer {
private static final String JSF_SERVLET_NAME = "jsf";
private static final String JSF_SERVLET_MAPPING = "*.xhtml";
#Override
public void onStartup(ServletContext servletContext) throws ServletException {
AnnotationConfigWebApplicationContext rootContext =
new AnnotationConfigWebApplicationContext();
rootContext.register(Config.class);
ServletRegistration.Dynamic jsf = servletContext.addServlet(
JSF_SERVLET_NAME, new FacesServlet());
jsf.addMapping(JSF_SERVLET_MAPPING);
servletContext.setInitParameter("javax.faces.STATE_SAVING_METHOD", "client");
servletContext.addListener(new ContextLoaderListener(rootContext));
}
}
I've tried to add servletContext.addListener(new ConfigureListener()); line on my WebApplicationInitializer class but then the project sometimes works and sometimes doesn't.
I'm using 2.2.1 version of jsf (jsf-api & jsf-impl).
