Problems migrating from 4.0.4 to 5.0.0B3

[nickdegraeve]

We're currently using JBoss 4.0.4 but we want to migrate to JBoss 5. We know, the 5 is still beta but we want to do some tests anyway.

We think we modified the necessary config files, for datasources, JMS, ... but our EJBs won't deploy. We're getting a ClassCastException because of org.jboss.metadata.ejb.spec.EjbJar20MetaData.

Any idea what might be wrong?

Are there docs yet about the migration from 4.0 to 5.0?

Thanks,

Nick.

Are you starting the app server with your application already in the deploy directory, or are you hot-deploying (starting the app server first and then copying your application to the deploy directory after the app server is started)?

The reason I ask is that about 1/2 of my applications will not deploy correctly if they are in the deploy directory when the app server starts, but these same applications deploy just fine if I hot deploy them.

Of course, this is not a solution but will could get you by until the deployment issues are fixed.

[nickdegraeve]

We get the same error regardless whether we deploy them from start-up or use hot-deploy.
We have several JARs with EJBs and so far only 1 of them was successfully deployed.

[peterj]

You might try deploying your EJBs to JBossAS 4.2.2. That will at least tell you if the problem is one of configuration (if the EJBs do not successfully deploy to 4.2.2) or a problem with the rewrite of the deployers for 5.0 (if the EJBs deploy successfully to 4.2.2).

[nickdegraeve]

We did some more testing and we found out that the problem is caused by Hibernate. If we remove all Hibernate POJOs from the archive it deploys.

Even with a simple POJO it fails. We have no clue as to why. Do you?

Thanks.

POJO:

Entity
@Table(name = "allowed_locales")
public class AllowedLocale implements Serializable {

 /** Primary key. */
 private Integer allowedLocaleId;

 private String allowedLocale;

 private Boolean usedForLogging;

 public AllowedLocale() {
 }

 @Id @GeneratedValue
 public Integer getAllowedLocaleId() {
 return allowedLocaleId;
 }

 public void setAllowedLocaleId(Integer allowedLocaleId) {
 this.allowedLocaleId = allowedLocaleId;
 }

 @Column(updatable = true, name = "allowedLocale", nullable = true, length = 5)
 public String getAllowedLocale() {
 return allowedLocale;
 }

 public void setAllowedLocale(String allowedLocale) {
 this.allowedLocale = allowedLocale;
 }

 @Column(updatable = true, name = "usedForLogging", nullable = true, length = 1)
 public Boolean getUsedForLogging() {
 return usedForLogging;
 }

 public void setUsedForLogging(Boolean usedForLogging) {
 this.usedForLogging = usedForLogging;
 }

}

Hibernate config:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
 "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
 "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

PS. Should I start a new thread here in the Hibernate section or on the Hibernate forum?
