[JBoss-user] [Persistence,JBoss/CMP, Hibernate, Database] - Schema update creates sequence in wrong schema
Hi all,
Has anyone ever experienced this?
I used to hardcode the schema name in my entity beans, but now I use a static
import of the schema name
(thinking that this would make it easy to switch between a live version and a
debug version of the database-model)
But when I set DB_SCHEMA_REQFORM from its original value "reqform" to
"reqform_debug" and redeploy the project, the sequences are still created in
"reqform". Why is that, I wonder?
import static be.barc.reqform.server.system.DB.DB_SCHEMA_REQFORM;
|
| @Entity(access = AccessType.FIELD)
| @Table(name = "c_layout_fonts",
| schema = DB_SCHEMA_REQFORM
| )
| @SequenceGenerator(name = "LayoutFontBeanSequence", sequenceName =
"s_layout_fonts")
| public class LayoutFontBean implements Serializable {
|
| @Id(generate = GeneratorType.SEQUENCE, generator =
"LayoutFontBeanSequence")
| private long id;
|
| ...
|
| }
cheers

[JBoss-user] [Beginners Corner] - Re: ClassCastException for remote acccess of entity bean
Can an entity bean have a local and remote interface or doest that only apply to session beans? Anyway, I'm accessing the entity bean through an SLSB (using the dao-pattern found in Hibernate in action). A call to findAll().size() will return the correct amount of records in my table. But the call findById() throws the ClassCastException when I try to assign the returnvalue to an object of the entity bean's class. Here is how my packages roughly look like: One.ear: - entity bean (to oracle, no interface) - stateless session bean (dao implementation and interface) Two.ear: - stateless session bean (a facade that calls the dao from one.ear causing the exception at the cast) So far no luck using PortableRemoteObject. Thanks for the help Kurt ... but keep it coming ;-) Or any idea where I can find an example where multiple ear files are deployed where this kind of remoting is used?

[JBoss-user] [Beginners Corner] - ClassCastException for remote acccess of entity bean
Hi, I'm working on JBoss 4.0.3SP1 and I'm trying to access an entity bean deployed in one.ear one from two.ear. I've been messing around a bit because I can't get it to work. I've deployed both ears, and have put a jar-file containing all classes from one.ear in the lib directory of the server. (otherwise two.ear didn't find the classes it needed) But now, when I try to get the entity bean from one.ear and use it in two.ear I get a ClassCastException. The strange thing is when I do a findAll() of the entity beans in two.ear, and show the number of entities that are found, the correct number is shown. But from the moment I actually want to use the entity object, the error is thrown. Anyone have an idea how I can get this thing to run? And how I can deploy my two.ear so that it does find all classes it needs and without putting the jar-file in the lib folder? tnx View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3935808#3935808 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3935808 --- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.

[JBoss-user] [Persistence,JBoss/CMP, Hibernate, Database] - Index annotation
I was wondering if is is possible to put an index annotation on a column or joincolumn of an entity bean, so that the JBoss server would automatically create the indexes together with the rest of the schema. I found some links about XDoclets dbindex, but I'm not sure if this is helpfull.

[JBoss-user] [Beginners Corner] - Re: Stop automatic persist of parents children?
Solved it! Apparently it had nothing to do with read-only beans but with the way JBoss 4.0.2 checks for dirty entity beans. Upgrading to 4.0.3SP1 solved the problem. BTW, the performance increase is HUGE.

[JBoss-user] [Beginners Corner] - Re: Stop automatic persist of parents children?
I found out that the simple parent-child example I gave, does not produce the
selection statements I was talking about. Instead a parent-child-grandchild
relation does produce the problem.
I used the following classes to test (the getters and setters are removed here)
:
|
| // Parent
|
| @Entity(access = AccessType.FIELD)
| @Table(name="t_tests", schema="grid")
| @SequenceGenerator(name="TestBeanSequence", sequenceName="grid.s_tests")
| public class TestBean implements Serializable {
|
| @Id(generate=GeneratorType.SEQUENCE, generator="TestBeanSequence")
| private Integer id;
|
| @Column(length=255)
| private String someText;
|
| @Basic(temporalType = TemporalType.TIMESTAMP)
| private DatesomeDate;
|
| private Boolean someBoolean;
|
| @OneToMany(targetEntity=TestChildBean.class,
| mappedBy="test",
| cascade=CascadeType.ALL,
| fetch=FetchType.LAZY)
| private List testChildren;
| }
|
|
| // Child
|
| @Entity(access = AccessType.FIELD)
| @Table(name="t_testchilds", schema="grid")
| @SequenceGenerator(name="TestChildBeanSequence",
sequenceName="grid.s_testchilds")
| public class TestChildBean {
|
| @Id(generate=GeneratorType.SEQUENCE, generator="TestChildBeanSequence")
| private Integer id;
|
| @Column(length=20, nullable=false)
| private String name;
|
| @ManyToOne(targetEntity=TestBean.class, fetch=FetchType.LAZY)
| @JoinColumn(name="test_id", nullable = false)
| private TestBean test;
|
| @OneToMany(targetEntity=TestGrandChildBean.class,
| mappedBy="testChild",
| cascade=CascadeType.ALL,
| fetch=FetchType.LAZY)
| private List testGrandChildren;
| }
|
| // Grandchild
|
| @Entity(access = AccessType.FIELD)
| @Table(name="t_testgrandchilds", schema="grid")
| @SequenceGenerator(name="TestGrandChildBeanSequence",
sequenceName="grid.s_testgrandchilds")

[JBoss-user] [Beginners Corner] - Re: Stop automatic persist of parents children?
Interesting. I found the following link http://e-docs.bea.com/workshop/docs81/doc/en/core/index.html at the bea website. Where in the section 'Developing Enterprise JavaBean' > 'Developing Entity Beans' > 'Accelerating Entity Bean Data Access' they give a few pointers on how to make entity beans that are read only. I wonder if I could do the same in JBoss and if this would prevent the server from trying to update each entity bean?

[JBoss-user] [Beginners Corner] - Stop automatic persist of parents children?
Hi, I came upon this problem when looking at the hibernate queries that JBoss AS executes for bi-directional relations (i.e. parent-child). The problem is that when a method of a session bean is called and in that method a parent entity bean is used, then after finishing the method the server will execute a ton of select statements for the children. My guess, to merge or update the children. But seeing as I only access properties, I would like a way to stop this automatic update of the children. If anyone knows a way, I'm all ears. The annotations for parent and children I use now look as follows: | | // in the parent entity bean | | @OneToMany(targetEntity=ChildBean.class, | mappedBy="parent", | cascade=CascadeType.ALL, | fetch=FetchType.LAZY) | private List children; | | | // int the child entity bean | | @ManyToOne(targetEntity=ParentBean.class, fetch=FetchType.LAZY) | @JoinColumn(name="parent_id", nullable = false) | private ParentBean parent; | | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3914186#3914186 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3914186 --- This SF.net email is sponsored by: Splunk Inc.

[JBoss-user] [JCA/JBoss] - Transaction does not rollback
I'm having problems using transactions on JBoss 4.0.2.
When I throw an error in some method of a SLSB with CMP that is part of a
transaction, then the changes made inside the method prior to the exception are
persisted.
So it seems as though the container persists the changes from the moment I make
them and not after finishing the method:
An example:
|
| @Stateless
| @Remote(GridSession.class)
| @TransactionManagement(TransactionManagementType.CONTAINER)
| public class GridSessionBean implements GridSession, Serializable {
|
| @PersistenceContext(unitName="gridManager")
| private EntityManager em;
|
| private boolean standalone = false;
|
| private DAOFactory getDAOFactory() {
| DAOFactory factory;
| if (standalone) {
| factory = DAOFactory.HIBERNATE_PERSISTENCE;
| } else {
| factory = DAOFactory.EJB3_PERSISTENCE;
| }
| return factory;
| }
|
| @TransactionAttribute(TransactionAttributeType.REQUIRED)
| public void testTransaction() throws Exception {
|
| // get dao
| DAOFactory factory = getDAOFactory();
| TestDAO testDao = factory.getTestDAO();
| testDao.setEm(em);
|
| // get the testbean with id = 1
| TestBean testBean = testDao.findById(1, false);
|
| testBean.setSomeText("this text may not be persisted");
|
| // throw an exception
| if (true) throw new Exception("Make transaction rollback");
|
| testBean.setSomeDate(new Date());
| }
|
In this example the table grid.t_tests contains one tuple with id = 1 and some
defaults for the other columns.
When I call this method on a client and look at the database after the
exception was thrown, the string "this text may not be persisted" was persisted.
Any help on getting this transaction to rollback would be appreciated.
