I am following here for the tutorials in the docs, I edited the files accordingly and deployed the nodes and when trying to initiate a new flow I'm getting the following error
I am running the following command from node B
"start IOUFlow iouValue: 99, otherParty: "O=PartyB,L=New York,C=US"
and the error is:

cmd output
what should I do?
You're trying to start a flow where Node B is both the initiator and the target party. That will break FinalityFlow in Corda 4.0.
Check here for more details and a workaround.
You are trying to open a session with the local node.
A.k.a, you are running the flow on partyB's node and trying to send a transaction to partyB.

I'm getting a java.util.zip.ZipException: invalid bit length repeat when attempting to retrieve a AuthnRequest with the opensaml library HTTPRedirectDeflateDecoder. I'm receiving the deflated and encoded SAMLObject thorough a GET request. This is the code I'm using to retrieve the object

decoder.setHttpServletRequest(request);
try {

throw new Exception("error in decoding authnrequest", e);

Any help is appreciated,

Found the error, This was a mistake from the data I was testing with. I used a deflated/encoded AuthnRequest. Since this is a GET request, I had to also URL decode the SAML Object.
I use Apache Kafka Streams the Processor API.
I create a remote object that extends the UnicastRemoteObject inside the StateStore of the Processor.
When the init(ProcessorContext) method of the Processor (which extends the AbstractProcessor) of my topology is called I put a ProcessorContext reference inside that remote Object.
public void init(ProcessorContext processorContext){
super.init(processorContext);
this.myStore = (MyCustomStore<String, String>)context().getStateStore("mystore");
this.myStore.getRemoteObject().setProcessorContext(processorContext);
}
If I access the ProcessorContext only remotely and use the forward method to send records to a sink processor it works fine. And if I access the ProcessorContext only locally to send records with forward it works fine, too.
If I access the ProcessorContext both locally and remotely to use forward I have NPE. I used a synchronized method in which foward is called because I thought that two different threads try to access ProcessorContext at the same time but the NPE insists.
It seems to me that somehow the same thread calls forward at the same time
both locally and remotely and that throws NPE.
The message is:
java.lang.NullPointerException

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:
2019-01-07 17:35:57,513 ERROR: o.s.b.c.s.AbstractStep [SimpleAsyncTaskExecutor-10] Encountered an error executing step 2 in job0

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)

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 have recently started trying to learn java and finished a spring/hibernate course in aims to implement a solution to some problems at work in my spare time. Needless to say, I have hit a snag.
I am wondering if anyone can see anything obviously wrong with the code attached below that can cause the following error:

Basically I am looking to move data between tables after a small vetting period (1 hour) I have successfully added timestamps and a few other functions such as search, api calls etc so far.
The end goal of this is to attach a scheduler and have it run periodically throughout the day but for now I have added a url mapping to trigger it manually.
When hitting the URL I receive the above error:
My Code:
Controller code
#GetMapping("/archiveproducts")
public String archiveDownloads (){
List<Downloads> theDownloads = downloadsService.getDownloads();
for (Downloads archiveDownload : theDownloads) {
// display the download ... just for clarity
System.out.println(archiveDownload);
Date timer = new Date();
Date purge = archiveDownload.getTimestamp();
long hours = (timer.getTime() - purge.getTime()) / DateTimeConstants.MILLIS_PER_HOUR;
if (hours >= 1) {
downloadsService.archiveProduct(archiveDownload);
}
}
return "list-downloads";
}
DownloadsDAOimpl Code: (java:128)
public List<Downloads> archiveProduct(Downloads archiveDownload) {
Session currentSession = sessionFactory.getCurrentSession();
Query theCopyQuery =
currentSession.createQuery("insert into Archive(fieldOne, fieldTwo, fieldThree, fieldFour, fieldFive, , fieldSix, FieldSeven)"
+ "sfieldOne, fieldTwo, fieldThree, fieldFour, fieldFive, , fieldSix, FieldSeven from Downloads where id=:theId");
theCopyQuery.setParameter("theId", archiveDownload);
theCopyQuery.executeUpdate();
List<Downloads> archiveProducts = theCopyQuery.getResultList();
Query theDeleteQuery =
currentSession.createQuery("delete from Downloads where id=:theId");
theDeleteQuery.setParameter("theId", archiveDownload);
theDeleteQuery.executeUpdate();
// return the results
return archiveProducts;
}
DownloadsServiceImpl.java:65
#Override
#Transactional
public List<Downloads> archiveProduct(Downloads archiveDownload) {
return downloadsDAO.archiveProduct(archiveDownload);
}
I understand that it's telling me I cannot cast an entity as an integer. but I don't understand where this integer is coming from or how to fix/reslove it.. I have a used a similar code approach for one of the API's and it worked okay.
#PostMapping("/listdownloads")
public List<Downloads> addDownloads (#RequestBody List<Downloads> theDownloads){
for (Downloads tempDownload : theDownloads) {
// display the download ... just for clarity
tempDownload.setId(0);
tempDownload.setTimestamp(null);
System.out.println(tempDownload);
// save to the database
downloadsService.saveProduct(tempDownload);
}
Cheers,
Danny
I think the issue is with this line.
theDeleteQuery.setParameter("theId", archiveDownload);
It is expecting an integer as Id but you passing Downloads object as mentioned in eror message. you can try something like this.
theDeleteQuery.setParameter("theId", archiveDownload.getId());
I am trying to deploy a book application which will display some book information and also allow user to add,remove,delete,upload/download etc.But while i am trying to deploy the application i am getting error of object is not an instance of delaring class .I don't know how to solve this erro please help i am posting my exception

My guess is that in your showBooks() or generateUrls() method you cast an object to another object or do something with an object that is illegal. If you could post the code in the two methods mentioned I could give you a better answer.
As the problem lies deeper within the stacktrace, my guess is that you have some files on the classpath that better shouldn't be there, or are on there twice. Make sure that you have, for example, portlet.jar in the appserver's global classpath and not in your webapp's WEB-INF/lib. Same goes for portal-impl.jar, that one should live within Liferay, but nowhere else - neither global nor your application.
Also, it might help to mark some line numbers. You have several appearances of response.createRenderURL in the code and it'd be good to know if the problem is in the first appearance or some time later.
