I'm not able to select particular column from a JPQL?

here is my query where I'm trying to get id and userNotes from Job Class.
#Query("SELECT j.id, j.userNotes FROM Job j WHERE j.bookingTime BETWEEN :stDate AND :edDate")
List<Job> getDriverCalendar(#Param("stDate") Timestamp stDate, #Param("edDate") Timestamp edDate);

#Query("SELECT j FROM Job j WHERE j.bookingTime BETWEEN :stDate AND :edDate") this query returned the complete Job object.

Your query doesn't select a Job. It selects two fields. Such a JPQL query returns a List<Object[]>, where each array of the list has two elements.
The return type of the method should thus be changed to List<Object[]>.

In the above query use the alias name for each value fetched
You will get the result as the list of hashmap so change the return type from List<Job> to List<Map> as shown below,
#Query("SELECT j.id as id , j.userNotes as userNotes FROM Job j WHERE j.bookingTime BETWEEN :stDate AND :edDate")
List<Map> getDriverCalendar(#Param("stDate") Timestamp stDate, #Param("edDate") Timestamp edDate);

com.fasterxml.jackson.databind.JsonMappingException: Infinite recursion (StackOverflowError)

I'm trying implement a rest service. I have created my entitys and daos, and when use this everthyng works fine.
But when I trye expose the information in rest json, the infinite recursion error occur.
I have read many topic about this error, but not is so clear for me.
I'm have tried so many alternatives that is hard talk about each.
When I debug my code, I see that the data from dao is correctly, the problem occur when I trie use json. Whe I use jsf page works fine.
I have tried use Gson and return String in my rest method, but stackoverflow error occur to.
Bellow I post my implememtation (all), because a dont have idea about the problem.
I using wildfly server...
Thanks in advance

What can I do?

Your Composer.class has two fields annotated with #Id. In SQL you can have only one primary key. If both the field should compose your primary key, consider using a composite primary key, see for example the JPA documentation, where it says:
Composite primary keys are denoted using the javax.persistence.EmbeddedId and javax.persistence.IdClass annotations.

SPRING JPA - org.hibernate.PersistentObjectException: detached entity passed to persist:

I've been stuck here for almost a week trying find the answer on the internet but sadly nothing worked. :( Everytime I try to update using this method:
private Tenant updateTenantWithApplicationProperties(List<TenantApplicationProperty> newTenantApplicationProperties, String tenantId) {
String reason = "Update application properties.";
Tenant existingTenant = tenantRepository.findById(tenantId);
List<TenantApplicationProperty> temp = existingTenant.getTenantApplicationProperties();
existingTenant.setTenantApplicationProperties(newTenantApplicationProperties);
setApplicationPropertiesUpdateValues(temp, existingTenant);
if(newTenantApplicationProperties != null && newTenantApplicationProperties.size() != 0) {
Tenant savedTenantWithAppProps = saveTenantWithLog(existingTenant, reason);
return savedTenantWithAppProps;
}

But when Im using this method it works fine:
public Tenant updateTenant(Tenant tenant) {
List<Database> databases = tenant.getDatabases();

validateUpdateTenant(tenant);
validateDatabases(databases);
validateAdministrators(administrators);

Database existingEcomDb = getDatabaseByType(listExistingDatabases,
TenantManagerConstants.ECOM_DATASOURCE);
setDatabaseUpdateValues(listExistingDatabases, tenant);
setAdministratorsUpdateValues(existingTenant.getAdministrators(),
tenant);
setProductUpdateValue(existingTenant.getProduct(), tenant);
setApplicationPropertiesUpdateValues(existingTenant.getTenantApplicationProperties(), tenant);
setEcomDBParamsDefaultValues(tenant);
setAdministratorDefaultValues(tenant);
Database updateEcomDb = getDatabaseByType(tenant.getDatabases(),
TenantManagerConstants.ECOM_DATASOURCE);
Boolean shouldInstallNewDB = true;
if (existingEcomDb.getName().equalsIgnoreCase(updateEcomDb.getName())
&& existingEcomDb.getHost().equalsIgnoreCase(
updateEcomDb.getHost())
&& existingEcomDb.getPort().equals(updateEcomDb.getPort())) {
shouldInstallNewDB = false;
} else {
testEcomDBConnection(updateEcomDb);
}
int ecomDbTableCount = getEcomDBTableCount(updateEcomDb);

if (updatedTenant != null) {

In application property, you defined 1-1 relation like:
#OneToOne
#JoinColumn(name = "property_group_id")
private ApplicationPropertyGroup applicationPropertyGroup;
#OneToOne
#JoinColumn(name = "property_type_id")
private ApplicationPropertyType applicationPropertyType;
While you have not defined the same relation (note it should work bidirectionally i.e. say for e.g. if you as a person related to an employee id, then employee id is related to you as a person well) in individual property ApplicationPropertyGroup and ApplicationPropertyType.
You should add the same 1-1 relation in ApplicationPropertyGroup and ApplicationPropertyType with ApplicationProperty.

The relationship between GroupLevelBean and ParameterGroupBean is one to many.
I am getting an exception when i try to create a session object.
org.hibernate.MappingException: Could not determine type for: com.vrde.daems.bean.GroupLevelBean, at table: tbl_ParameterGroups, for columns: [org.hibernate.mapping.Column(level)]
Can anyone tell me what is the problem?

Because you are putting #Id and #GeneratedValue java persistence annotations above:
#Id
#GeneratedValue
private int ParameterGroupId;
and in same time above:
#Id
#GeneratedValue
public int getParameterGroupId() {
return ParameterGroupId;
}
Its enough just to put annotations above private int ParameterGroupId;
