Hello !
I'm using jboss-3.2.3 and have container configuration 'Standard CMP 2.x EntityBean
with cache invalidation' in distribution file
<jboss-home>/server//conf/standardjboss.xml. No chandes was made in this
container-configuration. MYCONF - is a tree that I've been copied from default server
fileset.

In my application there is a very simple CMP bean which is used for lookup repository
id by it's name. Code printed below.
package goldbit.telent.tariffer;
import javax.ejb.EntityBean;
import javax.ejb.EntityContext;
/**
* @ejb.bean name="TrafficRepositoryName"
* type="CMP"
* cmp-version="2.x"
* view-type="local"
* jndi-name="TrafficRepositoryNameBean"
* primkey-type="String"
* primkey-field="name"
* schema="traffic_repository"
*
* @ejb.persistence table-name="traffic_repository"
*
* @jboss.persistence
* datasource="java:/TarifferDS"
* datasource-mapping="SapDB"
* create-table="false"
* remove-table="false"
*
* @jboss.read-only read-only="true"
*
* @jboss.container-configuration
* name="Standard CMP 2.x EntityBean with cache invalidation"
*/
public abstract class TrafficRepositoryNameBean implements EntityBean {
/**
* @ejb.interface-method
* @ejb.persistent-field
* @ejb.persistence column-name="id" sql-type="int"
* @jboss.method-attributes read-only="true"
*/
public abstract Integer getId();
public abstract void setId(Integer id);
/**
* @ejb.interface-method
* @ejb.persistent-field
* @ejb.persistence column-name="name" sql-type="char"
* @jboss.method-attributes read-only="true"
*/
public abstract String getName();
public abstract void setName(String id);
public void setEntityContext(EntityContext context) {}
public void unsetEntityContext() {}
public void ejbActivate() {}
public void ejbPassivate() {}
public void ejbLoad() {}
public void ejbStore() {}
public void ejbRemove() {}
}
It's really very simple and do nothing except looking repository ID by name hopefully
in cache due to container-configuration with commit-option A.
After xdoclet generation I got next configuration:
in EJB-JAR.XML:
<![CDATA[]]>
<ejb-name>TrafficRepositoryName</ejb-name>
<local-home>goldbit.telent.tariffer.TrafficRepositoryNameLocalHome</local-home>
goldbit.telent.tariffer.TrafficRepositoryNameLocal
<ejb-class>goldbit.telent.tariffer.TrafficRepositoryNameBean</ejb-class>
<persistence-type>Container</persistence-type>
<prim-key-class>java.lang.String</prim-key-class>
False
<cmp-version>2.x</cmp-version>
<abstract-schema-name>traffic_repository</abstract-schema-name>
<cmp-field >
<![CDATA[]]>
<field-name>id</field-name>
</cmp-field>
<cmp-field >
<![CDATA[]]>
<field-name>name</field-name>
</cmp-field>
<primkey-field>name</primkey-field>
<!-- Write a file named ejb-finders-TrafficRepositoryNameBean.xml if you
want to define extra finders. -->
in JBOSS.XML:
<ejb-name>TrafficRepositoryName</ejb-name>
<local-jndi-name>TrafficRepositoryNameLocal</local-jndi-name>
<read-only>true</read-only>
<configuration-name>Standard CMP 2.x EntityBean with cache
invalidation</configuration-name>
<method-attributes>
<method-name>getId</method-name>
<read-only>true</read-only>
<method-name>getName</method-name>
<read-only>true</read-only>
</method-attributes>
in JBOSSCMP-JDBC.XML:
<ejb-name>TrafficRepositoryName</ejb-name>
java:/TarifferDS
<datasource-mapping>SapDB</datasource-mapping>
<create-table>false</create-table>
<remove-table>false</remove-table>
<read-only>true</read-only>
<table-name>traffic_repository</table-name>
<cmp-field>
<field-name>id</field-name>
<column-name>id</column-name>
</cmp-field>
<cmp-field>
<field-name>name</field-name>
<column-name>name</column-name>
</cmp-field>
<!-- jboss 3.2 features -->
<!-- optimistic locking does not express the exclusions needed -->
Ok, then I use my CMP object from some other place in my project:
private TrafficRepositoryNameLocalHome trafficRepositoryNameHome;
TrafficRepositoryNameLocal trafficRepository_ =
trafficRepositoryNameHome.findByPrimaryKey("Repository Name");
Integer id_ = trafficRepository_.getId();
And that's working very fast. But sometimes I get error from this code:
Error 0: javax.ejb.CreateException: Could not create
entity:com.sap.dbtech.jdbc.exceptions.DatabaseException: [250]: Duplicate secondary
key:TRAFFIC_REPOSITORY_UK_I

What's wrong whith the container ? It's looking like inserting new record into
database. But I wrote my bean class to be stict read-only. May be I've missed
something in configuration ?
Isn't it a bug ?
Thanks in advance for any help!
Leonid Maksimshin.
