i'm getting a null pointer exception when i'm trying to persist.
i'm going to list files that i think related with the error .
can someone help me ?
this is my class opmanagerImpl

The problem is that you're manually creating opmanagerImpl xx instance:
public static void main(String[] args) {
opmanagerImpl xx = new opmanagerImpl();
//rest of the code...
}
When using Spring, you should not create your beans manually, instead let Spring create them and obtain an instance of the bean through the application context. Change the code to:
public static void main(String[] args) {
ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext("classpath*:META-INF/applicationContext1.xml");
opmanagerImpl xx = ctx.getBean("dao", opmanagerImpl .class);
opération op = new opération(15, 'f', 120, "bonjour", null, 12, 15);
xx.creerOpération(op);
//System.out.println("hiiiiiiiiiiii");
}

Dao classes are #Transactional and #Repository.
in MqttImplement class service object is null i think autowired is not working with Quartz scheduler. Any suggestion????
i think autowired is kind of resolved. but
error is-- org.springframework.beans.NotWritablePropertyException: Invalid property 'sessionFactory' of bean class [org.springframework.scheduling.quartz.SchedulerFactoryBean]: Bean property 'sessionFactory' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?
i am new to it. so may be some foolish mistakes i have done, please have a look.
Have you tried #Autowired without static? Seems weird for me...
From other side you do this:
MqttImplement mqttPublishTms=new MqttImplement();
................
mqttPublishTms.publishMessage();
So, it's new not Dependency Injection. There is no surprise that the service property there is null.

Setting up Tomcat JDBC connection pool with the Spring JDBCTemplate

I'm trying to setup a Tomcat connection pool (to MySQL) in my Java web app, while using the Spring JDBCTemplate.
This is the Java class to create the connection pool:
#Configuration
public class DataAccessConfiguration {
#Bean(destroyMethod = "close")
public javax.sql.DataSource datasource() {
org.apache.tomcat.jdbc.pool.DataSource ds = new org.apache.tomcat.jdbc.pool.DataSource();
ds.setDriverClassName("org.h2.Driver");
ds.setUrl("jdbc:h2:java-config");
ds.setUsername("sa");
ds.setPassword("");
ds.setInitialSize(5);
ds.setMaxActive(10);
ds.setMaxIdle(5);
ds.setMinIdle(2);
return ds;
}
#Bean public JdbcOperations tpl() {
return new JdbcTemplate(datasource());
}
}
This is how I get the ApplicationContext (in the main method for example):
public static void main(String[] args) {
ApplicationContext context =
new ClassPathXmlApplicationContext("Beans.xml");
How should I define the DataAccessConfiguration class in the Beans.xml file so Spring knows to use it?
**
Update:
**
This is the actual configuration method:
public javax.sql.DataSource datasource() {
org.apache.tomcat.jdbc.pool.DataSource ds = new org.apache.tomcat.jdbc.pool.DataSource();
PoolProperties p = new PoolProperties();
p.setUrl("jdbc:mysql://localhost:3306/mysql");
p.setDriverClassName("com.mysql.jdbc.Driver");
p.setUsername("root");
p.setPassword("");
p.setJmxEnabled(true);
p.setTestWhileIdle(false);
p.setTestOnBorrow(true);
p.setValidationQuery("SELECT 1");
p.setTestOnReturn(false);
p.setValidationInterval(30000);
p.setTimeBetweenEvictionRunsMillis(30000);
p.setMaxActive(100);
p.setInitialSize(10);
p.setMaxWait(10000);
p.setRemoveAbandonedTimeout(60);
p.setMinEvictableIdleTimeMillis(30000);
p.setMinIdle(10);
p.setLogAbandoned(true);
p.setRemoveAbandoned(true);
p.setJdbcInterceptors(
"org.apache.tomcat.jdbc.pool.interceptor.ConnectionState;"+
"org.apache.tomcat.jdbc.pool.interceptor.StatementFinalizer");
ds.setPoolProperties(p);
return ds;
}
Can you please help rewrite in the Beans.xml?
For the values passed in Properties setter methods exist. Therefore XML-based bean definition goes like:
<bean name="dataSource" class="org.apache.tomcat.jdbc.pool.DataSource">
<property name="url" value="jdbc:mysql://localhost:3306/mysql"/>
<property name="driverClassName" value="com.mysql.jdbc.Driver"/>
....
</bean>
<bean name="tpl" class="org.springframework.jdbc.core.JdbcTemplate">
<property name="dataSource" ref="dataSource"/>
</bean>
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
destroy-method="close">
<property name="jdbcUrl" value="#{config['db.url']}" />
<property name="driverClass" value="#{config['db.driver']}" />
<property name="user" value="#{config['db.username']}" />
<property name="password" value="#{config['db.password']}" />
<property name="acquireIncrement" value="1" />
<property name="idleConnectionTestPeriod" value="300" />
<property name="minPoolSize" value="1" />
<property name="maxPoolSize" value="20" />
</bean>

Hibernate 4 + Spring + getHibernateTemplate().getSessionFactory().getCurrentSession()

Want to use Spring to automatically work with Hibernate 4 sessions
Also I like to extends DAO, for not create many DAO for many entities
But there is problem:
SessionDAO.java
public abstract class SessionDAO extends HibernateDaoSupport{
public void startSession() {
getSession().beginTransaction();
}
public void closeSession() {
getSession().getTransaction().commit();
}
public void addObject() {
startSession();
getSession().save(this);
closeSession();
}
public Session getSession()
{
return getHibernateTemplate().getSessionFactory().getCurrentSession();
}
}
Values.java
#Entity
#Table
public class Values extends SessionDAO {
private int valuesId;
private double amount;
private Date date;
//...getters, setters, etc
}
dispatcher-servlet.xml
<bean id="sessionFactory"
class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="annotatedClasses">
<list>
<value>entity.Crypto</value>
<value>entity.Values</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop>
<prop key="hibernate.show_sql">true</prop>
</props>
</property>
</bean>
<bean id="dataSource"
class="org.apache.tomcat.dbcp.dbcp.BasicDataSource">
<property name="driverClassName" value="oracle.jdbc.OracleDriver" />
<property name="url" value="jdbc:oracle:thin:#my.****.us-east-1.rds.amazonaws.com:1521:ORCL" />
<property name="username" value="****" />
<property name="password" value="****" />
</bean>
<bean id="transactionManager"
class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
<bean id="persistenceExceptionTranslationPostProcessor"
class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor"/>
When start server, receive:
INFO: HHH000206: hibernate.properties not found
When try to load page receive:
SEVERE: Servlet.service() for servlet [dispatcher] in context with path [] threw exception [Request processing failed; nested exception is java.lang.NullPointerException] with root cause
java.lang.NullPointerException
on line
return getHibernateTemplate().getSessionFactory().getCurrentSession();
What's wrong?
Don't get the session by extend HibernateDaoSupport, just inject SessionFactory in DAO.
private HibernateTemplate hibernateTemplate;
public void setSessionFactory(SessionFactory sessionFactory) {
this.hibernateTemplate = new HibernateTemplate(sessionFactory);
}

Is it possible to load properties from DB with Custom Spring PropertyPlaceholderConfigurer?
and is it also possible that datasource provided to custom PropertyPlaceholderConfigurer use specific property file in classpath?

Activemq - Exceeded the maximum number of allowed client connections

My acitvemq server always print error below :

-----post the code that we how to use the template now
the jmsTemplate wrapped in a class
public class MessageProducer {
private JmsTemplate jmsTemplate;
private ActiveMQQueue scoreQueue;
public void sendScoreQueue(Map<String, String> userMap) {
sendMessage(this.scoreQueue, userMap);
}
private void sendMessage(Destination destination, final Map<String, String> map) {
this.jmsTemplate.send(destination, new MessageCreator() {
public Message createMessage(Session session) throws JMSException {
MapMessage message = session.createMapMessage();
for (String key : map.keySet()) {
message.setStringProperty(key, (String) map.get(key));
}
return message;
}
});
}
}
And we use a thead to send call the MessageProducer class's sendScoreQueue method.
As follows:
//the code is old and ugly.that is the original position we call the mq.
ThreadUtils.execute(new Thread(new SendMsgThread(dycc, ScoreMQSendType.SEND_TYPE_SCORE)));
///
public class ThreadUtils {
protected static ThreadPoolExecutor executor = null;
public static Properties Props = null;
public static void execute(Thread thread) {
executor.execute(thread);
}
static {
if (executor == null)
Integer corePoolSize = 5;
Integer maximumPoolSize = 10;
Integer keepAliveTime = 3000;
executor = new ThreadPoolExecutor(corePoolSize, maximumPoolSize, keepAliveTime, TimeUnit.MINUTES,
new LinkedBlockingQueue());
}
}
public class SendMsgThread implements Runnable {
private Log log = LogFactory.getLog(SendMsgThread.class);
private Map<String, String> map;
private String type;
private static MessageProducer producer = null;
public SendMsgThread(Map<String, String> map, String type){
this.type = type;
this.map = map;
}
public void run() {
try {
if(type.equals(ScoreMQSendType.SEND_TYPE_SCORE) || type.equals(ScoreMQSendType.SEND_TYPE_REGISTER)) {
producer.sendMessage(map);
}
} catch (Exception e) {
this.log.error("sendMsgThread sendScoreQueue error.", e);
}
}
static {
if (producer == null) producer =
(MessageProducer )SpringContextHolder.getBean(MessageProducer .class);
}
}
For this scenario you should use PooledConnectionFactory instead of cachingConnectionFactory.
More information can be found here.The difference between them can be found here
I had the same problem recurring with same error, and the solution was obtained as a result of trial and error, use jms call to concurrent consumers max to 101, instead of 100, and see if results repeat, adding more to the value results the code executed further on debugger, you will reach a value when code works , Also the solution appears to be using a connection pool factory.
Try this, hope it works, rest my implementation is same as yours in bean file
