I have tried to run this code but it won't run... It just shows an error INFO: Detected dialect: W3C [Utils] [ERROR] [Error] java.lang.NullPointerException
Please help me with your valid suggestions
I have posted my Runner class file as well as console Error code for your clarification

java.lang.NullPointerException is usually caused when you try to use a reference that points to no location in memory (null) as though it were referencing an object. Calling a method on a null reference or trying to access a field of a null reference will trigger a NullPointerException.(https://stackoverflow.com/questions/218384/what-is-a-nullpointerexception-and-how-do-i-fix-it)
I'm trying to get a complex flow of jobs done in Spring Batch using a combination of multithreaded Steps and parallel jobs.
Right now I've set up 3 jobs (1, 2, 3), the first (1) of which is running before the others (as expected) and completing withouth issues. The other two (2,3) are supposed to run parallel, having some parallel Steps of their own. All these jobs I'm trying to run are being encapsulated within JobSteps and then run within a master job (0).
The problem only occurs at jobs 2 & 3, where some JobStep fails, not always at the same point, not always the same JobStep. This is the stacktrace of such exception:

I've done a bit of research and this kind of error normally shows up when the HSQLDB I'm using to store job information isn't properly set up for concurrency. However I'm already using the seemingly good config, with MVCC transaction mode:
#Configuration
public class HSqlDbConfig {
#Primary
#Bean("hsqldbDataSource")
public DataSource hsqldbDataSource() {
final SimpleDriverDataSource dataSource = new SimpleDriverDataSource();
dataSource.setDriver(new org.hsqldb.jdbcDriver());
dataSource.setUrl("jdbc:hsqldb:mem:mydb;sql.enforce_strict_size=true;hsqldb.tx=mvcc");
dataSource.setUsername("sa");
dataSource.setPassword("");
return dataSource;
}
}
These are my code fragments I use for the configuration of these jobs. Beginning with the main job (0):
#Bean
public Job job0(JobBuilderFactory jobBuilderFactory) {
getJobParameters();
jobLauncher = (JobLauncher) ctx.getBean("jobLauncher");
Flow job1 = getJob1();
Flow job2 = getJob2();
Flow job3 = getJob3();
Flow splitFlow = getSplitFlow(job2, job3);
return jobBuilderFactory.get("Master Job")
.incrementer(new RunIdIncrementer())
.start(job1)
.next(splitFlow)
.end()
.build();
}
How I get the Flow for jobs 2 & 3:
private Flow getJob2() {
Job j2 = (Job) ctx.getBean("job2");
DefaultJobParametersExtractor extractor = new DefaultJobParametersExtractor();
Step step0 = getJobStep(j2, extractor);
return new FlowBuilder<Flow>("job2")
.start(step0)
.build();
}
private Flow getJob3() {
Job j3 = (Job) ctx.getBean("job3");
Job j3k = (Job) ctx.getBean("job3K");
Job j3l = (Job) ctx.getBean("job3L");
DefaultJobParametersExtractor extractor = new DefaultJobParametersExtractor();
Step step0 = getJobStep(j3, extractor);
Step step1 = getJobStep(j3k, params1);
Step step2 = getJobStep(j3k, params2);
Step step3 = getJobStep(j3l, params3);
Step step4 = getJobStep(j3l, params4);
Flow flow1 = new FlowBuilder<Flow>("flowJ3f1")
.start(step1)
.next(step2)
.build();
Flow flow2 = new FlowBuilder<Flow>("flowJ3f2")
.start(step3)
.next(step4)
.build();
return new FlowBuilder<Flow>("job3")
.start(step0)
.split(taskExecutor)
.add(flow1, flow2)
.build();
}
Both getJobStep() methods:
private Step getJobStep(Job job, JobParametersExtractor extractor) {
return steps.get(job.getName())
.job(job)
.launcher(jobLauncher)
.parametersExtractor(extractor)
.build();
}
private Step getJobStep(Job job, JobParameters jobParameters) {
SimpleJobParametersExtractor extractor = new SimpleJobParametersExtractor();
extractor.setJobParameters(jobParameters);
return steps.get(job.getName())
.job(job)
.launcher(jobLauncher)
.parametersExtractor(extractor)
.build();
}
The idea is to get this structure to work, as parallelization of all task possible is a requirement for this project, and it should be sturdy enough to add other parallel jobs apart from 2 & 3. Also, all jobs and steps have been tested without concurrency and they work as intended.
I can provide more code if needed. Right now I feel in a dead end so every bit of help is appreciated.
EDIT: As #MahmoudBenHassine suggested, I've configured a JobRepository, TransactionManager and JobLauncher (it solved my first issue) like so:
#Bean(name = "myTransactionManager")
public DataSourceTransactionManager transactionManager(#Qualifier("hsqldbDataSource") DataSource dataSource) {
return new DataSourceTransactionManager(dataSource);
}
#Bean(name = "myJobRepository")
public JobRepository jobRepository(#Qualifier("hsqldbDataSource") DataSource dataSource,
#Qualifier("myTransactionManager") DataSourceTransactionManager dataSourceTransactionManager) throws Exception {
JobRepositoryFactoryBean factory = new JobRepositoryFactoryBean();
factory.setDataSource(dataSource);
factory.setTransactionManager(dataSourceTransactionManager);
factory.setIsolationLevelForCreate("ISOLATION_READ_COMMITTED");
factory.afterPropertiesSet();
return factory.getObject();
}
#Bean(name = "myJobLauncher")
public JobLauncher getJobLauncher(#Qualifier("myJobRepository") JobRepository jobRepository) throws Exception {
SimpleJobLauncher jobLauncher = new SimpleJobLauncher();
jobLauncher.setJobRepository(jobRepository);
jobLauncher.afterPropertiesSet();
return jobLauncher;
}
Then I run job 0 with the new JobLauncher and this exception occurs on the JobSteps from job3 (3K & 3L) EDIT: I've got a larger log extract to more context of what's happening:

Please note I use different JobParameters in getJob3() for each execution of job 3K and 3L (the same exception is thrown for that job too). The JobParameters I use are the following: EDIT: I've included a Random function in order to include a unique JobParameter:
Random randomizer = new Random(System.currentTimeMillis());
params1 = new JobParametersBuilder()
.addString(PROCESS, "Job 3K BAR" )
.addString("pos_cod", "BAR")
.addString("per_event", "EVENT")
.addString(IS_RET, FALSE)
.addLong("UNIQUE", randomizer.nextLong())
.toJobParameters();
params2 = new JobParametersBuilder()
.addString(PROCESS, "Job 3K 704" )
.addString("pos_cod", "704")
.addString("per_event", "EVENT")
.addString(IS_RET, FALSE)
.addLong("UNIQUE", randomizer.nextLong())
.toJobParameters();
params3 = new JobParametersBuilder()
.addString(PROCESS, "Job 3L BAR" )
.addString("pos_cod", "BAR")
.addString("per_event", "RET_EVENT")
.addString(IS_RET, FALSE)
.addLong("UNIQUE", randomizer.nextLong())
.toJobParameters();
params4 = new JobParametersBuilder()
.addString(PROCESS, "Job 3L 704" )
.addString("pos_cod", "704")
.addString("per_event", "RET_EVENT")
.addString(IS_RET, FALSE)
.addLong("UNIQUE", randomizer.nextLong())
.toJobParameters();
Having seen the duplicated job instance error keeps occurring as the JobLauncher is trying to launch the samen job (not its sibling with other JobParameters), I'm more inclined to think this is a problem with my JobRepository, but this is nothing more than speculation.
The Map based job repository is not intended for multi-threading. This job repository is by default configured with a ResourcelessTransactionManager.
Make sure to use the JDBC based job repository (even with an in-memory database like in your case) to properly support multi-threading and parallel processing along with a DataSourceTransactionManager.
As a side note, the SimpleDriverDataSource is not a pooled data source, I recommend to use one with a connection pool.
I'm trying to query bigquery from scala (2.11.8) using Simba JDBC Driver (bigquery jdbc 4.2) through anorm (2.5.3) and play framework (2.5.8) on Ubuntu 16.04. This si my code:
class BigQueryController #Inject() (#NamedDatabase("bigquery") db: Database) extends Controller {
case class VixStudioProduct(short_name: String)
def test = Action {
val names: Seq[String] = db.withConnection { implicit connection =>
val query = SQL("SELECT name FROM dataset.table")
query.as(SqlParser.scalar[String].*)
}
Logger.debug(s"products - $names")
Ok
}
}
but I'm getting the following error.

I've found this reported issue https://issuetracker.google.com/issues/35906079
The cause is the same because anorm use prepared statement.
thanks in advance for your help

I originally didn't have the "getEnvironment" method overridden. Based on some recommendations that I saw online, I overrode that method and increased both the connection timeout and key-value timeout to 10 seconds to see if that might help, but it did not. When I increased the timeout from the defaults to 10 seconds, the timeout of the document retrieval became exactly 10 seconds. The TimeoutException is occurring against a document that is trying to be retrieved using the document's key.
The application has the following specifications:
* Java version: 1.7
* spring-data-couchbase version: 2.1.1.RELEASE
* java-client version: 2.2.5
* IBM WebSphere version: 8.5
Is there something obvious that I am missing in the way I have things configured? Are there any other ideas out there of things that I can look at to repair this problem?

Below is my code. I am using remoting to get reference to the service. once i get the service reference and try to get event.dao call i get a NPE in EventServiceImpl class. When I use xml based config it works but i want it to be annotation based.
EventDao.class
public interface EventDao {
void saveEvent(Event employee);
List<Event> findAllEvents();
void deleteEmployeeBySsn(String ssn);
Event findBySsn(String ssn);
