CRUD Generator - Deployment Problem

[phicorp]

Hello All,

I have installed Seam beta 2 and the booking example is working as expected.

However when I use the CRUD generator in Eclipse JBoss IDE 1.5 I am unable to deploy the generated application.

To generate the application I create a new Java 5.0 project, a Hibernate configuration file, and a Hibernate console configuration, and then run the code generator to generate a Seam skeleton app via reverse engineering using a JDBC connection.

The generator runs without any errors or warning messages, and when I look at the generated JSPs and Java code, the JSPs look fine and all the generated Java classes look fine.

I then carry out the instructions in the generated readme.txt and run the build.xml file which compiles all of the source code successfully and reports that the build finished successfully.

I now start jboss-4.0.4RC1 but JBoss cannot deploy the application successfully. The error messages that I get from JBoss are as follows:

FATAL [org.hibernate.ejb.packaging.PersistenceXmlLoader] bookingDatabase JTA // The Seam booking example now not working

FATAL [org.hibernate.ejb.packaging.PersistenceXmlLoader] entityManager JTA // The CRUD application

ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/seamapp]] Exception sending context initialized event to listener instance of class org.jboss.seam.servlet.SeamListener
java.lang.IllegalArgumentException: java.beans.IntrospectionException: Method not found: isJndiName

ERROR [org.jboss.deployment.MainDeployer] Could not start deployment: file:/C:/jboss-4.0.4RC1/server/default/tmp/deploy/tmp5889seamapp.ear-contents/seamapp.war
org.jboss.deployment.DeploymentException: URL file:/C:/jboss-4.0.4RC1/server/default/tmp/deploy/tmp5889seamapp.ear-contents/seamapp-exp.war/ deployment failed

I also note that there is no correlation between the Hibernate configuration file that I specified in the project and the persistence.xml file that was generated by the Hibernate generator.

The Hibernate configuration file:

<?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">
<hibernate-configuration>
 <session-factory>
 <property name="hibernate.connection.driver_class">org.postgresql.Driver</property>
 <property name="hibernate.connection.password">phicorp_booking_dev_user</property>
 <property name="hibernate.connection.url">jdbc:postgresql://localhost:5432/phicorp_booking_development</property>
 <property name="hibernate.connection.username">phicorp_booking_dev_user</property>
 <property name="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</property>
 </session-factory>
</hibernate-configuration>

The generated persistence.xml file:

<entity-manager>
 <persistence-unit name="entityManager">
 <provider>org.hibernate.ejb.HibernatePersistence</provider>
 <jta-data-source>java:/DefaultDS</jta-data-source>
 <properties>
 <property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/>
 <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup"/>
 <property name="hibernate.transaction.flush_before_completion" value="true"/>
 <property name="hibernate.hbm2ddl.auto" value="create-drop"/>
 <property name="hibernate.show_sql" value="true"/>
 <property name="jboss.entity.manager.factory.jndi.name" value="java:/EntityManager"/>
 </properties>
 </persistence-unit>
</entity-manager>

I have tried to correct the problem by changing the generated persistence.xml file and by creating a phicorp-booking-ds.xml file in the JBoss server/default/deploy directory, but I still get the error message which states that JBoss cannot deploy the war file.

The changed persistence.xml file:

<entity-manager>
 <persistence-unit name="entityManager">
 <provider>org.hibernate.ejb.HibernatePersistence</provider>
 <jta-data-source>java:/phicorpBookingDataSource</jta-data-source>
 <properties>
 <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect"/>
 <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup"/>
 <property name="hibernate.transaction.flush_before_completion" value="true"/>
 <!-- property name="hibernate.hbm2ddl.auto" value="create-drop"/ -->
 <!-- property name="hibernate.show_sql" value="true"/ -->
 <property name="jboss.entity.manager.factory.jndi.name" value="java:/EntityManager"/>
 </properties>
 </persistence-unit>
</entity-manager>

phicorp-booking-ds.xml:

<?xml version="1.0" encoding="UTF-8"?>
<datasources>
 <local-tx-datasource>
 <jndi-name>phicorpBookingDataSource</jndi-name>
 <connection-url>jdbc:postgresql://localhost:5432/phicorp_booking_development</connection-url>

 <user-name>phicorp_booking_dev_user</user-name>
 <password>phicorp_booking_dev_user</password>
 </local-tx-datasource>
</datasources>

Any help on resolving the problems that I have encountered will be much appreciated.

I do not understand:
(1) Why there is no correlation between the Hibernate configuration file and the generated persistence.xml file?
(2) Why JBoss cannot deploy the war file successfully?

Many thanks,
Bruce.

(1) Because we did not yet implement that. Still the app should run against JBoss' default datasource.

(2) Looks like you have an old version of the Seam jar. Make sure you are using Seam 1.0 beta 2

[gavin.king]

It also looks like you are not running the latest version of Hibernate Tools. Try the nightly build of JBoss IDE.

http://download.jboss.org/jbosside/builds/nightly/buildResults.html

[phicorp]

I am definitely using the jboss-seam.jar file from the jboss-seam-1.0beta2.zip file that I downloaded on the 11th of February (2 days ago).

[gavin.king]

Then make sure you are using the latest nightly build of JBoss IDE.

[phicorp]

I am now using the latest nightly build of JBoss IDE.

When I deploy to jboss-4.0.4RC1 I am informed that JBoss cannot deploy the war file successfully. However this message is preceded by the following errors:

I am using the following configuration files:

Can you see any errors in my configuration, and comment on the @DataModelSelection error?

Many thanks,
Bruce.

[gavin.king]

So, the exception is this:

Missing value() for @DataModelSelection with multiple @DataModels


Show the code for the component that has multiple @DataMOdels

Oh, OK, this is a bug in the templates.

Please report in Hibernate Tools JIRA.

Should be:

@DataModelSelection("locationTablesList")

etc

Many thanks.
