[jboss-user] [JBoss Seam] - Stale Data until redeploy
I posted in the EJB 3.0 forum without much success, so I am hoping this forum can help me,
as the users are more active.
I am having a horrible time with stale data. In my seam app, I create jobs then list the
jobs, and I can click on a job to edit it. However, when I edit a job, the changes
absolutely refuse to show up in the listing of jobs, the listing of jobs only shows the
state of when I initially created a job, and NO changes.
This is really driving me mad and I am not sure how to fix it.
I am using MySQL InnoDB, and everything shows up as correct in the database. All the data
is current and right, however in my view, all the data is old. Is there some cache I need
to disable, or someway to can ensure the data for listing my jobs is not stale.
I've tried several things like giving the Query hints and disabling 2nd level cache in
the persistence.xml, but nothing works.
| @Name("viewJobs")
| @Stateful
| @Scope(ScopeType.SESSION)
| public class ViewJobsBean implements ViewJobs {
|
| @Logger
| private Log log;
|
| @DataModel
| private List<Job> jobs;
|
| @DataModelSelection
| private Job job;
|
| @PersistenceContext(type=EXTENDED)
| private EntityManager em;
|
| public String view() {
| Map parameters = new HashMap();
| StringBuffer queryString = new StringBuffer();
|
| queryString.append("from Job");
|
| Query query = em.createQuery(queryString.toString());
| // query.setHint("org.hibernate.cacheable", new Boolean(false));
| // query.setHint("org.hibernate.cacheMode", CacheMode.IGNORE);
| // query.setHint("org.hibernate.flushMode", FlushMode.ALWAYS);
|
| jobs = (List<Job>) query.getResultList();
| return "viewJobs";
| }
|
| public void delete(){
| em.remove(job);
| view();
| }
|
| public void refresh() {
| view();
| }
|
| @Destroy @Remove
| public void destroy() {}
| }
|
| <persistence>
| <persistence-unit name="entityManager">
| <provider>org.hibernate.ejb.HibernatePersistence</provider>
| <jta-data-source>java:/jobsDatasource</jta-data-source>
| <properties>
| <property name="hibernate.hbm2ddl.auto"
value="create-drop"/>
| <!--<property name="hibernate.hbm2ddl.auto"
value="update"/>-->
| <property name="hibernate.show_sql" value="true"/>
| <property name="hibernate.format_sql" value="true" />
| <!--<property name="hibernate.cache.use_second_level_cache"
value="false" />-->
|
| <!--<property name="hibernate.jdbc.batch_size" value="0"
/>-->
| <property name="jboss.entity.manager.factory.jndi.name"
value="java:/jobsEntityManagerFactory"/>
| </properties>
| </persistence-unit>
| </persistence>
|
|
The only way to Can get the changes to the jobs to show up is if I redeploy the web app.
Am I missing something?
Help with this is greatly appreciated
