This is the bean code for cron scheduler. declaration for runMeTask And runMeJob
<bean id="runMeTask" class="com.ascent.fieldomobify.cornScheduler.RunMeTask"/>
<bean name="runMeJob" class="org.springframework.scheduling.quartz.JobDetailBean">
<property name="jobClass" value="com.ascent.fieldomobify.cornScheduler.RunMeJob" />

</bean>
<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="triggers">
<list>
<ref bean="cronTrigger" />
</list>
</property>
</bean>
it get call directly from bean scheduler configuration
The first class is RunMeJob
public class RunMeJob extends QuartzJobBean {
private RunMeTask runMeTask;
public void setRunMeTask(RunMeTask runMeTask) {
this.runMeTask = runMeTask;
}
protected void executeInternal(JobExecutionContext context)
throws JobExecutionException {
try {
runMeTask.printMe();
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
form here i call the controller's method which is having the logic
Second class RunMeTask
public class RunMeTask{
#Autowired
WorkOrderController workorderContoller;
public void setWorkorderContoller(WorkOrderController workorderContoller) {
this.workorderContoller = workorderContoller;
}
public void printMe() throws ParseException {
workorderContoller.printSysOut();
}
}
there are some scenarios where you can get that behavior, please check this thread: Java Spring #Scheduled tasks executing twice

I am calling the sendMessage function from Main method and it gives Null Pointer Exception while creating the object Queue (this.queue).
Main method:
public void start()
{
AuthorisationServiceImpl authorisationServiceImpl = new AuthorisationServiceImpl();
try {
authorisationServiceImpl.fromMain();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public static void main(String[] args) throws InterruptedException {

You are getting a NullPointerException when trying to invoke this.jmsTemplate.send(...) method, because your jmsTemplate variable is NULL, or never initialized. One more thing is that you are not using the spring bean authorisationServiceImpl, but you are instantiating the class manually.
First you need to set the jmsTemplate in your bean:
<bean id="authorisationServiceImpl" class="aero.sita.uatp.server.AuthorisationServiceImpl">
<property name="jmsTemplate" ref="jmsTemplate" />
<property name="messageSender" ref="messageSender" />
<property name="configProperties" ref="configProperties" />
</bean>
Second you should not instantiate the class:
AuthorisationServiceImpl authorisationServiceImpl = new AuthorisationServiceImpl();
try {
authorisationServiceImpl.fromMain();
}
But get it from application context, that you have just created
AuthorisationServiceImpl authorisationServiceImpl = context.getBean("authorisationServiceImpl", AuthorisationServiceImpl.class );
Help! I'm using Spring+Hibernate and I'm trying to use AOP like this :
package ua.i.pustovalov.table;
enter code here
#Aspect
public class Aoprad {
#Pointcut("execution(* *getAll(..))")
public void performance() {
}
public Aoprad() {
}
#Around("performance()")
public void AfterAndPriv(ProceedingJoinPoint joinPoint) {
try {
System.out.println("Open query");
joinPoint.proceed();
System.out.println("Close query");
} catch (Throwable e) {
e.printStackTrace();
}
}
}
When I try to use my method, it returns null.
public class TestDao {
public static void main(String[] args) {
ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(
new String[] { "applicationContext.xml" }, true);
DaoInterface das = (DaoInterface) context.getBean("dataDao");

return getSession().createCriteria(Student.class).list();
}
}
And interface
public interface DaoInterface {
Student get(int id);
Student get(String text);
Collection<Student> getAll();
}
What steps can I take to debug this issue?
When using an around aspect you should always use a method signature that returns Object and not void and you should always return the result of the call to the proceed() method. If you fail to do so every method that is advices by this aspect will return null because there is nothing returned.
#Around("performance()")
public Object AfterAndPriv(ProceedingJoinPoint joinPoint) {
try {
System.out.println("Open query");
return joinPoint.proceed();
} catch (Throwable e) {
e.printStackTrace();
} finally {
System.out.println("Close query");
}
}
I am looking for a guidance/solution with Spring batch integration. I have a directory to which external application will send xml files. My application should read the file content and move the file to another directory.
The application should be able to process the files in parallel.
Thanks in advance.
You can use Spring Integration ftp / sftp combined with Spring Batch:
1.Spring Integration Ftp Configuration :
<bean id="ftpClientFactory"
class="org.springframework.integration.ftp.session.DefaultFtpSessionFactory">
<property name="host" value="${host.name}" />
<property name="port" value="${host.port}" />
<property name="username" value="${host.username}" />
<property name="password" value="${host.password}" />
<property name="bufferSize" value="100000"/>
</bean>
<int:channel id="ftpChannel" />
<int-ftp:outbound-channel-adapter id="ftpOutbound"
channel="ftpChannel" remote-directory="/yourremotedirectory/" session-factory="ftpClientFactory" use-temporary-file-name="false" />
2.Create your reader and autowire a service to provide your items if needed :
#Scope("step")
public class MajorItemReader implements InitializingBean{
private List<YourItem> yourItems= null;
#Autowired
private MyService provider;
public YourItem read() {
if ((yourItems!= null) && (yourItems.size() != 0)) {
return yourItems.remove(0);
}
return null;
}
//Reading Items from Service
private void reloadItems() {
this.yourItems= new ArrayList<YourItem>();
// use the service to provide your Items
if (yourItems.isEmpty()) {
yourItems= null;
}
}
public MyService getProvider() {
return provider;
}
public void setProvider(MyService provider) {
this.provider = provider;
}
#Override
public void afterPropertiesSet() throws Exception {
reloadItems();
}
}
3. Create Your Own Item Processor
public class MyProcessor implements
ItemProcessor<YourItem, YourItem> {
#Override
public YourItem process(YourItem arg0) throws Exception {
// Apply any logic to your Item before transferring it to the writer
return arg0;
}
}
4. Create Your Own Writer :
public class MyWriter{
#Autowired
#Qualifier("ftpChannel")
private MessageChannel messageChannel;
public void write(YourItem pack) throws IOException {
//create your file and from your Item
File file = new File("the_created_file");
// Sending the file via Spring Integration Ftp Channel
Message<File> message = MessageBuilder.withPayload(file).build();
messageChannel.send(message);
}
5.Batch Configuration :
<bean id="dataSourcee"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="" />
<property name="url" value="" />
<property name="username" value="" />
<property name="password" value="" />
</bean>
<bean id="jobRepository"
class="org.springframework.batch.core.repository.support.JobRepositoryFactoryBean">
<property name="dataSource" ref="dataSourcee" />
<property name="transactionManager" ref="transactionManagerrr" />
<property name="databaseType" value="" />
</bean>
<bean id="transactionManagerrr"
class="org.springframework.batch.support.transaction.ResourcelessTransactionManager" />
<bean id="jobLauncher"
class="org.springframework.batch.core.launch.support.SimpleJobLauncher">
<property name="jobRepository" ref="jobRepository" />
</bean>
6.Another ApplicationContext file to Configure Your Job :
<context:annotation-config />
<bean id="provider" class="mypackage.MyService" />
<context:component-scan base-package="mypackage" />
<bean id="myReader" class="mypackage.MyReader"
<property name="provider" ref="provider" />
</bean>
<bean id="myWriter" class="mypackage.MyWriter" />
<bean id="myProcessor" class="mypackage.MyProcessor" />
<bean id="mReader"
class="org.springframework.batch.item.adapter.ItemReaderAdapter">
<property name="targetObject" ref="myReader" />
<property name="targetMethod" value="read" />
</bean>
<bean id="mProcessor"
class="org.springframework.batch.item.adapter.ItemProcessorAdapter">
<property name="targetObject" ref="myProcessor" />
<property name="targetMethod" value="process" />
</bean>
<bean id="mWriter"
class="org.springframework.batch.item.adapter.ItemWriterAdapter">
<property name="targetObject" ref="myWriter" />
<property name="targetMethod" value="write" />
</bean>
<batch:job id="myJob">
<batch:step id="step01">
<batch:tasklet>
<batch:chunk reader="mReader" writer="mWriter"
processor="mProcessor" commit-interval="1">
</batch:chunk>
</batch:tasklet>
</batch:step>
</batch:job>
<bean id="myRunScheduler" class="mypackage.MyJobLauncher" />
<task:scheduled-tasks>
<task:scheduled ref="myJobLauncher" method="run"
cron="0 0/5 * * * ?" />
<!-- this will maker the job runs every 5 minutes -->
</task:scheduled-tasks>
7.Finally Configure A launcher to launch your job :
public class MyJobLauncher {
#Autowired
private JobLauncher jobLauncher;
#Autowired
#Qualifier("myJob")
private Job job;
public void run() {
try {
String dateParam = new Date().toString();
JobParameters param = new JobParametersBuilder().addString("date",
dateParam).toJobParameters();
JobExecution execution = jobLauncher.run(job, param);
execution.stop();
} catch (Exception e) {
e.printStackTrace();
}
}
All - In the Spring 3.0, in the applicationContext.xml .... are we supposed to have the bean property name and the reference value to be the same ? If I give a different value, it returns null object. But on giving the same value, it works. For my project, i am supposed to give different values for them. Kindly help. bye, HS
This works: (same values)

... is it that the name and bean should have the same value.... ??? No Need to be.....Am i right ? Please advise.

<property name="userDelegate" ref="userDelegate" />
name is the field name in your class. When name is userDelegate, it means that WIRAdminBaseAction has a field named userDelegate (and probably a setter setUserDelegate())
ref is the bean name you want to set this field to. In your example, you should have another bean, named userDelegate or bmoUserDelegate which should be set as userDelegate in WIRAdminBaseAction.
So if you want to use the second configuration:
You just need to create a bean with id bmoUserDelegate:
<bean id="bmoUserDelegate" class="mypackage.BmoUserDelegateClass"/>
I have two Quartz (1.8.3) jobs, configured via Spring (2.5.6), one of them writes (send) to database, and one reads from it (check).
<bean id="scheduleFactory"
class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="triggers">
<list>
<ref bean="Check"/>
<ref bean="Send"/>
</list>
</property>
</bean>
<bean id="Send" class="org.springframework.scheduling.quartz.CronTriggerBean">
<property name="jobDetail">
<bean class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<property name="targetObject" ref="StatusMonitor" />
<property name="targetMethod" value="sendMessage" />
</bean>
</property>
<property name="cronExpression" value="0 0/1 * * * ?" />
</bean>
<bean id="Check" class="org.springframework.scheduling.quartz.CronTriggerBean">
<property name="jobDetail">
<bean class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<property name="targetObject" ref="StatusMonitor" />
<property name="targetMethod" value="checkAndUpdateStatus" />
</bean>
</property>
<property name="cronExpression" value="30 0/1 * * * ?" />
</bean>
Transaction manager is set up:
<tx:annotation-driven transaction-manager="TransactionManager"/>
In both jobs I explicitly run read/write operations in transactions like this:
#Override
public synchronized void sendMessage() {
try {
TransactionTemplate tt = new TransactionTemplate(ptm);
tt.execute(new TransactionCallbackWithoutResult() {
#Override
protected void doInTransactionWithoutResult(TransactionStatus status) {
...
statusDAO.update(status);
...
}
});
log.info("Status was updated");
} catch (Exception e) {
...
}
}
where ptm is a TransactionManager bean, injected via Spring.
I see "Status was updated" record in logs, but when I read this record from transactional read method it is outdated sometimes. Moreover, when I use an SQL editor to read this record it is outdated too.
I don't understand, why transactions dont work in this case, do you have any ideas?
Thanks.
For anyone that might be interested. This worked for me
<bean name="applicationDataCollectorControllerJobDetail" class="org.springframework.scheduling.quartz.JobDetailBean">
<property name="jobClass" value="org.mypckage.controller.jobs.ApplicationDataCollectorController" />
<property name="jobDataAsMap">
<map>
<!--<entry key="timeout" value="1" />-->
<entry key="genericService" value-ref="genericService" />
<entry key="applicationDataCollectorService" value-ref="applicationDataCollectorService" />
<entry key="transactionManager" value-ref="transactionManager" />
</map>
</property>
</bean>
--- in the scheduler bean---
#Override
protected void executeInternal(JobExecutionContext ctx) throws JobExecutionException {
getApplicationDataCollectorService().collectData(transactionManager);
}
----In the applicationDataCollectorService bean-----
public void collectData( org.springframework.transaction.jta.JtaTransactionManager transactionManager) {
try {
this.transactionManager = transactionManager;
testTransactionalSave();
} catch (Exception e) {
BUSY = false;
e.printStackTrace();
}
}
}
private void testTransactionalSave() throws Exception {
TransactionTemplate tt = new TransactionTemplate(transactionManager);
tt.execute(new TransactionCallbackWithoutResult() {
#Override
protected void doInTransactionWithoutResult(TransactionStatus ts) {
try {
ApplicationParameter appPara = null;
List<ApplicationParameter> appParaList = genericService.getListFromHQL("select o from ApplicationParameter as o order by o.id desc", false);
if (appParaList != null) {
if (appParaList.size() > 0) {
appPara = (ApplicationParameter) appParaList.get(0);
appPara.setLastBankStatementMailNum(appPara.getLastBankStatementMailNum() + 10);
appPara = (ApplicationParameter) genericService.mergeObject(appPara);
System.out.println(" num is now = " + appPara.getLastBankStatementMailNum());
}
}
} catch (Exception ex) {
ex.printStackTrace();
}
}
});
}
Note: dont forget to declare transactionManager as private properties in both beans with public setter and getter for spring to wire it up. Any Questions? yemiosigbesan#gmail.com
