Entity Bean Verify Error JDO74033

[Balaji Anand]

hi
i am trying to deploy a entity bean and i get this verify error... any help?

For [ EntityCMP#ejb-jar-ic1.jar#EmployeeBean ]
Error: Exception [ JDO74033: Cannot deploy application 'EntityCMP' module 'ejb-jar-ic1' with CMP beans: cmp-resource is not defined for this module. The minimum requirement for a cmp-resource is to specify the jndi-name of a jdbc-resource or a persistence-manager-factory-resource to be used with the beans. ] while initializing JDOCodeGenerator. Please check your descriptors and mapping files for consistency

Thanks for any help in advance

I am using j2eesdk 1.4 and deploytool platform edition 8 with PointBase...

How do i go and specify the JNDI name for the DB?...
It is getting deployed with this error and iam able to run too.... what does this mean? then y is it giving this error?

[Balaji Anand]

Is there anyone to answer this?
Or can anyone tell me the steps they followed while creating an Entity Bean(take me thro the wizard)... am i missing something?

[Venu Navat]

how u hv created ur entity bean?..... using cmp or bmp?

[Venu Navat]

in which application server u hv deployed??

[Damanjit Kaur]

To specifiy cmp-resource :

in ejb-jar file write down the following tag

<resource-ref>
<res-ref-name>jdbc/DefaultDS</res-ref-name>
<res-type>javax.sql.Datasource</res-type>
</resource-ref>

DefaultDS i.e. the lookup name for your database that you have specified in database xml file in your server directory.

hi thanks for all your replies
i have created it as CMP bean and using Pointbase DB and the default server in j2eesdk 1.4

this is how my Application Server Descripton looks like


<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE sun-ejb-jar PUBLIC "-//Sun Microsystems, Inc.//DTD Application Server 8.0 EJB 2.1//EN" "http://www.sun.com/software/appserver/dtds/sun-ejb-jar_2_1-0.dtd">

</property>
</schema-generator-properties>
</cmp-resource>
</enterprise-beans>
</sun-ejb-jar>

Where do i find my Database xml file? how do i create a ref to the db?

Thanks for all your help

[Balaji Anand]

ok ... i found how to add the resource ref... but my question still is how to find the lookup name for the database .... where shd i look for that?

I hope this will solve my problem

[Balaji Anand]

what do i give for the sun specified settings for the coded name i give in Resource Ref Tab? do i have to give a user id and password? if so what i have togive?

[Damanjit Kaur]

I have not used Sun Application server. But I just downloaded it and saw this jndi name,password and username for Pointbase is specified in
C:\Sun\AppServerNew\domains\domain1\config\domain.xml file.

[Balaji Anand]

Thanks i could locate the JNDI name for pointbase as jdbc/PointBase. do i have to do that for CMP bean too?

[Balaji Anand]

hi
i could log on to http://localhost:4848/asadmin and see the jdbc resource being defined for jdbc/PointBase. and i defined a Resource Ref for the Entity bean with values

Coded name jdbc/Pointbase
type java.sql.DataSource
Authenticatin Container
Sharable yes
Jndi name jdbc/PointBase.
Is this ok?I am still getting this error.. do I have to do anything else?
Thank you so much for your reply

Hi

You need to configure your server. Follow the given steps in deploytool
Tools->server configuration->(Click on) Data Sources->(Click on) Standard

Here specify driver class, JNDI name, JDBC URL & restart server

It should work.

[Damanjit Kaur]

<resource-ref>
<res-ref-name>jdbc/DefaultDS</res-ref-name>
<res-type>javax.sql.Datasource</res-type>
</resource-ref>

This is specified for BMP bean only.

May be this link should help you, If you have not already went through it. http://docs.sun.com/source/816-7151-10/deassemb.html#66072

I read you have to specify either cmp-resource or pm-descriptor. so your sun-ejb-jar.xml file looks ok as you have specified cmp-resource tag.

[Damanjit Kaur]

Ok. read this from the above site i mentioned. Perhaps you will find the solution.

Configuring the Resource Manager

The resource manager used by the container-managed persistence implementation is PersistenceManagerFactory, which is configured using the Sun ONE Application Server DTD file, sun-server_7_0-0.dtd.

Refer to the Sun ONE Application Server Administrator's Guide for information on creating a new persistence manager.

To deploy an EJB module that contains container-managed persistence beans, you need to add the following information to the sun-ejb-jar.xml deployment descriptor.

1. Specify the Persistence Manager to be used for the deployment:

<pm-descriptors>
<pm-descriptor>
<pm-identifier>SunONE</pm-identifier>
<pm-version>1.0</pm-version>
<pm-class-generator>com.iplanet.ias.persistence.internal.ejb.ejbc.J DOCodeGenerator
</pm-class-generator>
<pm-mapping-factory>com.iplanet.ias.cmp.
NullFactory</pm-mapping-factory>
</pm-descriptor
<pm-inuse>
<pm-identifier>SunONE</pm-identifier>
<pm-version>1.0</pm-version>
</pm-inuse>
</pm-descriptors>

2. Specify the JNDI name of the Persistence Manager's resource (listed under persistence-manager-factory-resource entry in the server.xml file) and the JNDI name for cmp-resource. This name will be used at run time to manage persistent resources.

For example, if you have the following entry in the server.xml file:

<persistence-manager-factory-resource
factory-class="com.sun.jdo.spi.persistence.support.
sqlstore.impl.PersistenceMan
gerFactoryImpl"
enabled="true"
jndi-name="jdo/pmf"
jdbc-resource-jndi-name="jdo/pmfPM"
</persistence-manager-factory-resource>

Set the CMP resource as:

<cmp-resource>
<jndi-name>jdo/pmf</jndi-name
</cmp-resource>

I dont find this option in Application Server DeployTool Platform Edition 8?

Why do i have to go for JDO? cant i do it with JDBC?
