java.io.IOException: Stream closed with WS call - java

I am facing an issue, when I try to connect to the WS some time I am getting java.io.IOException: Stream closed. This is not reproducible systematically. If I run the same thing again it works well.
Can any body please help me ?
Code which calls this WS is
public Long startProcess(String pId, Map<String,Object> params) throws OmegaFunctionalException{//Start JBPM Process with parameter Map
LOG.debug("inside startProcess...");
LOG.debug("applicationConfiguration.getJbpmWsUrl() = {}", applicationConfiguration.getJbpmWsUrl().toString());
WorkflowHandlerServiceService webProvider = new WorkflowHandlerServiceService(applicationConfiguration.getJbpmWsUrl());
LOG.debug("webProvider.getPort...");
WorkflowHandlerService webService = webProvider.getPort(WorkflowHandlerService.class);
JbpmParameterItemArray itemArray = new JbpmParameterItemArray();
try {
itemArray.setItem(JbpmParameterItem.buildList(params));
LOG.debug("webService.startProcess...");
return webService.startProcess(pId, itemArray);
} catch (ClassNotFoundException | IOException ex) {
LOG.debug("ClassNotFoundException or IOException");
LOG.error(ex.getMessage(), ex);
throw new OmegaTechnicalException(ex);
} catch (OmegaWSException ex) {
LOG.debug("OmegaWSException");
Exception generatedException = ex.getFaultInfo().generateException();
if (generatedException instanceof OmegaFunctionalException){
LOG.debug("OmegaFunctionalException");
LOG.error(generatedException.getMessage(), generatedException);
throw (OmegaFunctionalException) generatedException;
}
LOG.error(generatedException.getMessage(), generatedException);
throw new OmegaTechnicalException(ex.getMessage(),generatedException);
} catch (Exception ex) {
LOG.debug("Exception......");
if (ex instanceof SOAPFaultException)
{
SOAPFaultException e = (SOAPFaultException) ex;
LOG.debug("ex.getFault().getFaultCode() : {}", e.getFault().getFaultCode());
LOG.debug("ex.getFault().getFaultCodeAsName() : {}", e.getFault().getFaultCodeAsName().toString());
LOG.debug("ex.getFault().getFaultCodeAsQName() : {}", e.getFault().getFaultCodeAsQName().toString());
LOG.debug("ex.getFault().getFaultString() : {}", e.getFault().getFaultString());
//LOG.debug("ex.getFault().getDetail() : {}", e.getFault().getDetail().toString());
}
LOG.error(ex.getMessage(), ex);
throw new OmegaTechnicalException(ex.getMessage(), ex);
}
}

Try to update the version of JRE and JAX-WS.

ClassCastException when invoking Query.uniqueResult()

I'm trying to get a count of line using Hibernate with a HQL query. I wrote the following code:
public long countTexteEstALOrdreDuJour(String examenId) throws DAOException {
StringBuilder hqlQuery = new StringBuilder();
hqlQuery.append("SELECT count(*) ")
.append("FROM Examen as e ")
.append("JOIN e.organeSaisi as os ")
.append("JOIN os.texteDeLoi as t ")
.append("WHERE e.organeSaisi = some (SELECT ex.organeSaisi FROM Examen as ex WHERE ex.id = :examenId) ")
.append("AND e.examenEstALOrdreDuJour = 1 ");
try {
Query query = this.getSession().createQuery(hqlQuery.toString());
query.setParameter("examenId", examenId);
String result = (String)query.uniqueResult();
Long ret = null;
if (result==null) {
ret = 0l;
} else {
ret = Long.parseLong(result);
}
return ret;
} catch (JDBCException e) {
throw new DAOException(String.valueOf(e.getErrorCode()), e);
} catch (HibernateException e) {
throw new DAOException("HibernateException ", e);
}
}
When I invoke the method, I get an exception:

What is happening?

Most likely in your Examen entity the id field is a numeric Long and should be set as such. Either change examenId type to Long or parse it when setting query parameter value:
Query query = this.getSession().createQuery(hqlQuery.toString());
query.setParameter("examenId", Long.parseLong(examenId));

And it is much better to obtain "count" as number at once. Something like
Long result = (Long) query.uniqueResult();

JSON String to List of objects

I've got the following JSON String which I receive. I try to convert the string to a List of objects using the given code here.

I tried using the TypeReference solution but it also gave me the above exception. It would be a great help if any one could identify the error I'm doing!

Your JSON matches an object (see HotelPromotionList below), not a list.
class HotelPromotionList {
List<HotelPromotion> hotelPromotions;
}
class HotelPromotion {
int id;
int version;
String description;
String status; // might be an enum
// ...
}

This works for me, use it for different types, hope this will help
public class RestMapper
{
private ObjectMapper objectMapper;
public <T> List<T> stringJsonToObject( String json, Class<T> objectType )
{
List<T> resultList = new LinkedList<T>();

try
{
arrObject = objectMapper.readValue( json, ListOfObjects.class );
for ( int i = 0; i < arrObject.getBody().size(); i++ )
{
T singleObject = objectMapper.convertValue( arrObject.getBody().get( i ), objectType );
resultList.add( singleObject );
}
}
catch ( IOException e )
{
e.printStackTrace();
}
return resultList;

an this is the method that i want to handle the exception it returns an ArrayList :
public List<Tache> listPhaseTaches(Integer idphaseKey) {
return new java.util.ArrayList<Tache>(phaseDAO.findPhaseByPrimaryKey(idphaseKey).getTaches());
}
The problem is I don't know what i should do for handling NullPointerException for a method that returns an Arraylist

List list = someMethod();
if(list!=null){
//your logic
}
else{
return new List<T>();
}
Make sure that you return not-null value

you can handle this like
List list = someMethod();
if(list!=null){
//your logic
}
else{
}

your error lies either at phaseDAO is null or phaseDAO.findPhaseByPrimaryKey(idphaseKey) this returns null OR phaseDAO.findPhaseByPrimaryKey(idphaseKey).getTaches() this returns null
Use this >>
public List<Tache> listPhaseTaches(Integer idphaseKey) {
if(phaseDAO!=null){
if(phaseDAO.findPhaseByPrimaryKey(idphaseKey)!=null){
if(phaseDAO.findPhaseByPrimaryKey(idphaseKey)!=null){
return new ArrayList(phaseDAO.findPhaseByPrimaryKey(idphaseKey));
}
}
}
return null;
}

Provide the following null checks:
phaseDAO != null
phaseDAO.findPhaseByPrimaryKey(idphaseKey) != null
phaseDAO.findPhaseByPrimaryKey(idphaseKey).getTaches() != null

Session is closed while creating Criteria

The following code throws SessionException at the line which creates the criteria object:
public User getUserByUsername(String username) {
try {
Criterion criterion = Restrictions.eq("username", username);
Criteria criteria = (Criteria) getSession().createCriteria(User.class).add(criterion);
return (User) criteria.uniqueResult();
}
catch(NullPointerException ex) {
return new User();
}
}
My getSession() method is as follows:
public Session getSession() {
if(session == null) {
session = hibernateUtil.getSessionFactory().getCurrentSession();
}
return session;
}
I have injected the hibernateUtil bean to the class which has getSession() method.
Following is the exception.

Your method of getting a session is rather weird. Yo shoul duse a sessionfactory, to obtain a session from within a transaction.
The session should not be an instance variable (assuming your using singleton scope services).

Jpa, Seam updating entity

I've got a Stateful Session bean where I create a object (in this case a user object) and saving it in my db. Now I just want so update this entry which doesn't work - a NullPointerExceptionis thrown instead. What is my fault here?
Bean
#Stateful
#Scope(ScopeType.SESSION)
#Name("Userdata")
public class UserdataBean implements Userdata {
#Logger
private Log log;
#In(create = true)
private Renderer renderer;
#In
private IdentityManager identityManager;
#In
private EntityManager entityManager;
#In
StatusMessages statusMessages;
#Out(required = false)
#In(required = false)
private User user;
private int registerType = -1;
private int loggedIn = 0;
#Destroy
#Remove
public void destroy() {
}
public String next() {
DLdapIdentityStore identityStore = (DLdapIdentityStore) identityManager.getIdentityStore();
if (loggedIn == 1) {
if (registerType == 2) {
entityManager.merge(getUser());
entityManager.flush();
} else {
identityStore.createOrUpdateUser(getUser(), false);
}
} else {
if (registerType == 1) {
if (!identityStore.createOrUpdateUser(getUser(), true)) {
log.error("User cannot be generated", null);
statusMessages.add(Severity.ERROR, "Benutzer konnte nicht erstellt werden", null);
return null;
} else {
log.info("User created successfully: " + getUser().getUserId(), null);
sendMailForUser();
}
} else if (registerType == 0) {
User userFromLdap = identityStore.getProductFinderUser(user);
if (userFromLdap == null) {
statusMessages.add(Severity.ERROR, "Benutzername oder Passwort falsch", null);
return null;
} else {
user = userFromLdap;
}
} else if (registerType == 2) {
getUser().setUserId(Long.toString(System.currentTimeMillis()));
entityManager.persist(getUser());
}
loggedIn = 1;
}
return "wf-confirm";
}
I've tried this approach too
User user = entityManager.find(User.class, getUser().getUserId());
user = getUser();
entityManager.flush();

Your code generally looks OK, the fault is most probably somewhere else (configuration or other code)
from the stack trace I can see that there is a NPE during hibernate entity validation, caused on a call at line 62 of your UserdataBean (most probably the merge method call).
You should see what operation is done at that line. Most probably one of the composed entities or a property(of User) is null while it should not be.
