Summary: 0002528: amber initialization order
Description: (rep by Riccardo Cohen)


I have one single entity ejb :

package adlejb;
import......
@Entity
@Table(name="adluser")
public class Ejbuser
{
 @Id @Column(name="adlid") @GeneratedValue int id;
 @Basic @Column(name="adlfirstname") String firstname;
 @Basic @Column(name="adlname") String name;
..

and the config in persistence.xml is :

<persistence xmlns="http://java.sun.com/xml/ns/persistence" [^] version="1.0">
 <persistence-unit name="Adlhessian">
   <class>adlejb.Ejbuser</class>
   <exclude-unlisted-classes />
 </persistence-unit>
</persistence>

But I continue to have the error =

com.caucho.amber.AmberRuntimeException: 'adlejb.Ejbuser' with classloader EnvironmentClassLoader[web-app:http://localhost:8000] [^] is an illegal instance class

What does it mean ? I found no error, and tried to have a look at mailinglist archive with no success. I looked at the samples, but found nothing really different...

The crazy about this is that I built this simple app from another simple app configured exactly the same manner, but the other does not make any amber error ! I tried to rename everything several times, but nothing seems to remove this error. I had the same problem sometimes with resin 3.0 and in 2006 Rodrigo Westrupp answered that I should work with resin 3.1.
Steps To Reproduce: <persistence xmlns="http://java.sun.com/xml/ns/persistence" [^] version="1.0">
 <persistence-unit name="Adlhessian">
   <class>adlejb.Ejbuser</class>
   <exclude-unlisted-classes />
 </persistence-unit>
</persistence>
<web-app xmlns="http://caucho.com/ns/resin"> [^]
 <database jndi-name="jdbc/adlhessian">
   <driver>
     <type>com.mysql.jdbc.Driver</type>
     <url>jdbc:mysql://localhost/adlhessian</url> [^]
     <init-param autoReconnect="true"/>
     <init-param noDatetimeStringSync="true"/>
     <init-param jdbcCompliantTruncation="false"/>
     <user>hessian</user>
     <password>hessian</password>
   </driver>
   <prepared-statement-cache-size>8</prepared-statement-cache-size>
   <max-connections>20</max-connections>
   <max-idle-time>30s</max-idle-time>
   <spy>true</spy>
 </database>
 <ejb-server data-source="jdbc/adlhessian" create-database-schema="false"/>
 <servlet servlet-name="adlservice" servlet-class="adlhessian.Adlservice"/>
 <servlet-mapping url-pattern="/adlservice/*" servlet-name="adlservice"/>
</web-app>
