I upgraded this jar files and issue solved.
jackson-annotations-2.7.4.jar
jackson-core-2.7.4.jar
jackson-databind-2.7.4.jar
And added filter in web.xml

spring.datasource.username=root
spring.datasource.password=password
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=validate
spring.jpa.database-platform=org.hibernate.dialect.MySQLDialect
i use two dependencies for the databse:
<artifactId>spring-boot-starter-data-jpa</artifactId>
and
<artifactId>mysql-connector-java</artifactId>
can someone help me?
Thanks.

HQL is different from Native SQL, for one main reason: you query objects and not actual database tables.
Try this query instead:
String query = "SELECT u FROM User u WHERE u.username = :username";

Hibernate 4.x - Inserting Clob as String to database (Oracle - MySql)

I recently upgraded from Hibernate 3.x to 4.x, I used this article as a reference.
I am facing a problem when inserting Clob data as a String to the database, my application runs on (Oracle - MySql - MSSQL) databases. This is my hibernate domain:
#Lob
#Column(name = "LargeText" )
public String getLargeText() {
return largeText;
}
public void setLargeText(String largeText) {
this.largeText = largeText;
}
When I try to insert the object to the database, this exception is being thrown:

What can I do to solve this issue?

This exception has various paths to solve it. This exception may occurs due to version to Tomcat server used along with mysql-connector-java version and also which dpcp implementation (commons.dbcp or tomcat-dbcp) is used and it's version of course.
According to discussion in chat OA #Shahe is using Tomcat 7 along with mysql-connector-java version 5.1.35 which is latest one but #Shahe is using commons.dpcp with version 1.2.2 which was the problem.
So updating the version of commons-dpcp to 1.4 or latest will solve the issue.

Issue in querying the task assigned to user jBPM5

I am querying the task assigned to a user using the task service provided by jBPM5. Am getting one exception which is occasional in nature.
The way through which I am querying the task is having one method which will invoke by taking the userId as parameter. I am using the human task service api which internally use its own mechanism to query the task assigned to user.
public List<TaskSummary> getTasksAssignedToUser(String userId) {
TaskService taskService = this.humanTaskServiceHandler.getTaskService();
List<TaskSummary> taskSummary = taskService.getTasksAssignedAsPotentialOwner(userId, WorkflowConstants.LANGUAGE);
LOGGER.debug("TaskSummary found: " + taskSummary.size());
return taskSummary;
}
Occasionally this method causing the runtime exception as mentioned below

This is how I am configuring the entity manager for jbpm task service

I am using the same data source (oracleDataSource) for one of my hibernate layer, does it make any difference here?
And here is my task-persistence.xml

Greetings,
Mayank

There seems to be an issue with spring and the entity manager that is created inside the task service, there could be a conflict there, you will need to check if spring is messing things up with that. Are you using the spring persistence mechanisms to store something else?
