I try PersistenceException, GenericJDBCException, JDBCConnectionException, HibernateException, but no one of these works. These exceptions is because i stopped my SQL server and i want to catch it.
The code is simple reading:
selectAll() {
EntityManager manager = Persistence.createEntityManagerFactory(
"DictionaryWithJPA").createEntityManager();
try {
List<Dictionarytable> dict = manager.createQuery(
"SELECT d FROM Dictionarytable d", Dictionarytable.class)
.getResultList();
for (Dictionarytable duma : dict) {
System.out
.println(duma.getWord() + " " + duma.getDescription());
}
} catch (GenericJDBCException ce) {
System.out.println("Не може да се свърже с базата данни");
} finally {
manager.close();
}
}
Read the stack trace:
at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:39)
at model.MainDictionary.selectAll(MainDictionary.java:27)
That means that this exception, of type javax.persistence.PersistenceException (as also indicated by the stack trace), is thrown by the call to
Persistence.createEntityManagerFactory()
at line 27 of your class. And your try block starts after this method call. So obviously, it can't catch the exception thrown before.
Reading error messages provides invaluable information. You have to learn doing that.

I trying to touch some service outside with CXF 3.0.0.
But got very strange behavior like sometimes it is working and sometimes it is failing with stacktrace attached (it can process multiple requests before failing). Request body is the same. Code for sending request is the same.
Any advice about this?
There are some logs attached. Left side with success, right with case when request was failed.

Left - Success. Right - FAIL.
Found the issue. Our request happens via proxy, these proxy servers are load balanced across multiple data centers. One of the data centers is not configured correctly, that’s why the connection cannot be established. Then our request gets timed out intermittently.

Hi all i got a solution for this. According to documentation from this site: http://www.mastertheboss.com/jboss-jbpm/jbpm6/configuring-jbpm-6-to-use-a-non-default-database need to change the persistence.xml from jbpm-console.war/WEB-INF/classes/META-INF/persistence.xml. This is available in deployment folder i moved this out and changed
<property name="hibernate.dialect" value="org.hibernate.dialect.H2Dialect" />
to
<property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect" />
and move jbpm-console.war to deployment folder through Dockerfile. Then without any change its starts working.
I am working on Openshift, on a Tomcat 7 (JBoss EWS 2.0) with MySQL 5.5 and phpMyAdmin 4.0. I am trying to connect to the database, but everytime this MySQLNonTransientConnectionException jumps.
Originally, the exception was Communication link failure, but I added the autoReconnect thing to the URL (I read that it was a workaround to this problem), but it hasn't worked.
Here is the stack trace:
com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Could not create connection to database server. Attempted reconnect 10 times. Giving up.

Also, here is the code for the connection (I have used this same code, except for the autoreconnect part, in other project some months ago and it worked).
private Connection conexion = null;
public static boolean initConnection() {
try {
Class.forName("com.mysql.jdbc.Driver");
// Variables de entorno para crear la url de acceso
String name = System.getenv("OPENSHIFT_APP_NAME");
System.out.println(name);
String host = System.getenv("OPENSHIFT_MYSQL_DB_HOST");
System.out.println(host);
String port = System.getenv("OPENSHIFT_MYSQL_DB_PORT");
System.out.println(port);
// url de acceso a la bd
String url = "jdbc:mysql://" + host + ":" + port + "/" + name +
"?autoReconnect=true&failOverReadOnly=false&maxReconnects=10";
// usuario y password de la bd
String user = System.getenv("OPENSHIFT_MYSQL_DB_USERNAME");
System.out.println(user);
String password = System.getenv("OPENSHIFT_MYSQL_DB_PASSWORD");
System.out.println(password);
// crear la conexion con la bd
conexion = (Connection) DriverManager.getConnection(url, user, password);
return true;
} catch (SQLException e) {
// Excepcion SQL
System.err.println("Error al conectar con la base de datos");
e.printStackTrace();
} catch (ClassNotFoundException e) {
// Excepcion del driver
System.err.println("Driver de MySQL no encontrado");
e.printStackTrace();
}
return false;
}
I have looked my my.conf file, and I cannot change the binding address, which is not set to 0.0.0.0 nor 127.0.0.1.
Any help will be appreciated.
EDIT: I cannot download the my.conf file from the server so I can say:
Configurable values:
lower_case_table_names
default-storage-engine
max_connections
ft_min_word_len
ft_max_word_len
Other things, but I cannot touch them:
skip-name-resolve
bind-address=127.6.41.2
Sorry if it's not entirely accurate, I cannot copy the file. I have seen in other answers the bind-address thing, but since I cannot change it...
I have a local websphere server that I want to use to pull content from a webpage. when I make a get request to the server, I get a huge error. It seems to be getting triggered by getting the input stream from the connection..
Here's my code (not actually trying to read from google it's just a placeholder)
URL url = new URL("https://google.ca");
URLConnection conn = url.openConnection();
BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
It only breaks when I enter the third line, I get this error

any help would be greatly appreciated.
Likely a firewall issue, the TCP connect() to google.ca timed out. You'd probably meet the same result If you can test outside of the application server on the same system.
Using BoneCp 0.7.1
I setup my application and everything is working fine, but then the DB went offline.
On the next application request getConnection() started throwing internal exceptions and the retry mechanism kicked in but getConnection() never returned leaving the thread hanging.
The below exception gets thrown over and over but you would expect getConnection() to return NULL or throw an SQLException at least so you can handle it.
This seems similar: http://jolbox.com/forum/viewtopic.php?t=339&p=1390 But my problem arise after connections are established.
Also saw this... BoneCP doesn't recover from broken connection
I will try 8.0-rc1

Tried 8.0-rc2 same issue getConnection() wont return.
Old question, but may I suggest trying HikariCP for improved recoverability.
