I have two step. In the first step i create a file and pass file to reader (as a resource) with name INPUT_FILENAME using the following code:
JobExecution jobExecution = chunkContext.getStepContext().getStepExecution().getJobExecution();
ExecutionContext executionContext = jobExecution.getExecutionContext();
String filePath = "file://" + FilenameUtils.separatorsToUnix(mydFile.getAbsolutePath());
executionContext.put("INPUT_FILENAME", filePath);
<batch:job id="transformJob" job-repository="jobRepository">
<batch:step id="step1" next=step2">
<batch:tasklet ref="step1Tasklet" />
<batch:listeners>
<batch:listener ref="promotionInputFileNameListener" />
</batch:listeners>
</batch:step>
<batch:step id="step2">
<batch:tasklet transaction-manager="imTransactionManager">
<batch:chunk reader="step2Reader" writer="step2Writer" commit-interval="${step2.interval}" />
</batch:tasklet>
</batch:step>
<bean id="promotionInputFileNameListener" class="org.springframework.batch.core.listener.ExecutionContextPromotionListener">
<property name="keys" value="INPUT_FILENAME"/>

<bean id="step1Tasklet" class="com.ProduceFileTasklet" scope="step"/>

The StepContext of step2 is never auto refreshed by promoter.

I see step 2 is looking for the input file from #jobParameters, but in the code snippet it is set on the execution context not a parameter. So instead it looks like it should look for the file name in #jobExecutionContext.

No value for key [org.hibernate.internal.SessionFactoryImpl] bound to thread [main]

Recently, I've updated my hibernate to version 5.2.1.Final (the latest by now) and spring framework to 4.3.0.RELEASE. When I start the application in class StartUp
#Service
public class StartUp {
#Autowired(required = true)
private IUserService userSrv;
public void init() throws UnsupportedEncodingException {
User user = userSrv.single(admin_filter);
....
}
}
and by the execution of line
User user = userSrv.single(admin_filter);
I get this exception:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'startUp' defined in ServletContext resource [/WEB-INF/mvc-dispatcher-servlet.xml]: Invocation of init method failed; nested exception is java.lang.IllegalStateException: No value for key [org.hibernate.internal.SessionFactoryImpl#6568f998] bound to thread [main]

Just Found the solution. after updating the hibernate, instead of using :
<bean id="txManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
<property name="dataSource" ref="dataSource" />
</bean>
And
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
...
</bean>
try these:
<bean id="txManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
And
<bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
...
</bean>

HSQLDB auto update schema

For instance, I have the following entity:
#Entity
public class MyClass {
#Id
#GeneratedValue
private Integer Id;
private String value;
private boolean check = false; // <-- HERE!
// getters & setters
}
If I decide to change the check property's name to validate:
#Entity
public class MyClass {
#Id
#GeneratedValue
private Integer Id;
private String value;
private boolean validate = false; // <-- HERE!
// getters & setters
}
I had configured a hsqldb with:
<bean id="hikariConfig" class="com.zaxxer.hikari.HikariConfig" autowire="no" >
<property name="poolName" value="springHikariCP" />
<property name="dataSourceClassName" value="org.hsqldb.jdbc.JDBCDataSource" />
<property name="dataSourceProperties">
<props>
<prop key="url">jdbc:hsqldb:file:${user.home}/db/data;hsqldb.lock_file=false</prop>
<prop key="user">sa</prop>
<prop key="password"></prop>
</props>
</property>
</bean>
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="packagesToScan" value="com.example.domain" />
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />
</property>
<property name="jpaProperties" ref="hibernateProperties" />
</bean>
<bean name="hibernateProperties" autowire="byName"
class="org.springframework.beans.factory.config.PropertiesFactoryBean">
<property name="properties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.HSQLDialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop> // <-- HERE!
<prop key="hibernate.default_schema">PUBLIC</prop>
<prop key="hibernate.current_session_context_class">org.springframework.orm.hibernate4.SpringSessionContext</prop>
<prop key="hibernate.connection.CharSet">utf8</prop>
<prop key="hibernate.connection.characterEncoding">utf8</prop>
<prop key="hibernate.connection.useUnicode">true</prop>
</props>
</property>
</bean>
As the hibernate.hbm2ddl.auto is set to update shouldn't it update the schema if I make any change at the code?
I got this error trying to access validate because the schema wasn't updated:

UPDATED:
after turn on the sql log I see this:
ERROR org.hibernate.tool.hbm2ddl.SchemaUpdate (SchemaUpdate.java:261) main :HHH000388: Unsuccessful: alter table PUBLIC.my_class add column validate boolean not null
ERROR org.hibernate.tool.hbm2ddl.SchemaUpdate (SchemaUpdate.java:262) main :default expression needed in statement [alter table PUBLIC.my_class add column validate boolean not null]
I don't know why is not adding the default false to the statement. In addition it's trying to add a new column instead of update it

because boolean can't be null, I notice that initialize at the object the validate=false doesn't have any effect. So I force to do it in JPA with:
#Column(columnDefinition = "boolean default false")
private boolean validate = false;

This error represents you don't have enough privileges on the schema you are currently working on.
Check the below line.
Caused by: org.hsqldb.HsqlException: user lacks privilege or object not found: MYCLAS0_.VERIFY
Validate if you have update schema permission on this said schema. Use this link thi understand more about this.

I'm quite sur I'm making a common mistake that costs me a lot of time, so any help would be welcome.
Thank you a lot.

Set entityManager components.xml seam weblogic

I develop an application with Seam 2.2.0 on weblogic 10.3
In my components.xml, when I set my entityManager, I do this:
<persistence:managed-persistence-context name="entityManager"
auto-create="true" persistence-unit-jndi-name="OSSPortailDataSource" />
My DataSource is configured like this on weblogic:
JNDI name: OSSPortailDataSource
Driver class: oracle.jdbc.OracleDriver
URL: jdbc:oracle:thin:#10.1.18.98:1522:ossi
Now, when I run my application, I get this error:
java.lang.ClassCastException: weblogic.jdbc.common.internal.RmiDataSource cannot be cast to javax.persistence.EntityManagerFactory
Here is the log:

How do I configure the persistence to work fine ?
Thanks.

I found the solution:
In the components.xml, add the following property:
<persistence:entity-manager-factory name="entityManagerFactory"
persistence-unit-name="OSSPortail" />
It's a "link" to the persistence.xml (hibernate configuration).
In the components.xml, modify the managed-persistence-context property:
<persistence:managed-persistence-context name="entityManager"
auto-create="true" entity-manager-factory="#{entityManagerFactory}" />
Just add the entity-manager-factory attribute which is the name of the persistence:entity-manager-factory property.
Finally, configure the persistence.xml file. Mine is here:
<persistence-unit name="OSSPortail" transaction-type="JTA">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>OSSPortailDataSource</jta-data-source>
<properties>
<property name="hibernate.dialect"
value="org.hibernate.dialect.Oracle10gDialect" />
<property name="hibernate.connection.driver_class"
value="oracle.jdbc.driver.OracleDriver" />
<property name="hibernate.hbm2ddl.auto" value="update" />
<property name="hibernate.show_sql" value="true" />
<property name="hibernate.format_sql" value="true" />
<property name="hibernate.default_schema" value="SI" />
<property name="jboss.entity.manager.factory.jndi.name"
value="OSSPortailDataSource" />
<property name="hibernate.transaction.manager_lookup_class"
value="org.hibernate.transaction.WeblogicTransactionManagerLookup" />
<property name="hibernate.query.factory_class"
value="org.hibernate.hql.classic.ClassicQueryTranslatorFactory" />
</properties>
</persistence-unit>
