CDI + JPA + EJB + JTA + JSF --JBoss-Kitchen Example with PostgreSQL?

Question

I am trying to learn the new technologies CDI + JPA + EJB + JTA + JSF so, i have downloaded the sample project from JBoss-Community --> jboss-as-kitchensink(from JBoss in my Eclipse juno).

I am Trying to connect the kitchen with my PostgreSQL database:
My database name is : sampledb

My Table(Member) Structure is : Database name : QUICKSTART_DATABASENAME

CREATE TABLE member
(
  id integer, 
  name text,
  email text,
  phone_number numeric
);

I have edited this files in my kitchen Project :

persistence.xml

<persistence version="2.0"
   xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="
        http://java.sun.com/xml/ns/persistence
        http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
   <persistence-unit name="primary">
     <jta-data-source>java:jboss/datasources/PostgreSQLDS</jta-data-source>
      <properties>
         <!-- Properties for Hibernate -->
          <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect"/>
           <property name="hibernate.show_sql" value="true"/>

      </properties>
   </persistence-unit>
</persistence>

I Added the Dependency in pom.xml :

<!-- PostgreSQL Dependency -->
    <dependency>
        <groupId>postgresql</groupId>
        <artifactId>postgresql</artifactId>
        <version>9.1-901.jdbc4</version>
    </dependency>

But i'm getting error:

What should i do so that i can run this application with my database to insert the data.

Do i need to change any code in .java files or any .xml file to make it work?

EDITED after Comments: By Following this link ,I have configured my PostgreSQL into JBoss manually by setting up the standalone-full.xml file of JBoss..

Answer :

Install the PostgreSQL driver and use the XML so that u can make it work.

Follow The Steps : (Suggested By @Craig Ringer ) is Very HelpFull

Download PgJDBC . I'm assuming you're using postgresql-9.2-1003.jdbc4.jar, the current version at time of writing. Adjust any filenames to match if you need a different version.

Now deploy the JDBC driver to JBoss AS 7 by putting it in the deployments folder or using the deploy command in jboss-cli. This will work for most, but not all, purposes.

Alternately, you an define a PostgreSQL JDBC driver module:

Create the path $JBOSS_HOME/modules/org/postgresql/main. The modules/org part should already exist, make directories for the rest.

In $JBOSS_HOME/modules/org/postgresql/main/modules.xml with the following content, changing the resource-root entry for the PgJDBC driver to refer to the driver you wish to use.

 <?xml version="1.0" encoding="UTF-8"?>
    <module xmlns="urn:jboss:module:1.1" name="org.postgresql">
         <resources>
             <resource-root path="postgresql-9.2-1003.jdbc4.jar"/>
         </resources>
         <dependencies>
             <module name="javax.api"/>
             <module name="javax.transaction.api"/>
             <module name="javax.servlet.api" optional="true"/>
         </dependencies>
     </module>

Into the same directory as modules.xml place postgresql-9.2-1003.jdbc4.jar
Open jboss-cli by running $JBOSS_HOME/bin/jboss-cli --connect

Run the command:

/subsystem=datasources/jdbc-driver=postgresql-driver:add(driver-name=postgresql-driver, driver-class-name=org.postgresql.Driver, driver-module-name=org.postgresql)

Now create any required data sources, etc, using postgresql-driver as the driver name.

You can create a datasource via the web ui, with jboss-cli with the data-source create command (see data-source --help, data-source add --help), or by deploying a -ds.xml file like this:

<?xml version="1.0" encoding="UTF-8"?>
<datasources>
  <datasource jndi-name="java:/datasources/PostgresqlDS" enabled="true" use-java-context="true"  
        pool-name="PostgresqlDS">
    <connection-url>jdbc:postgresql:dbname</connection-url>
    <driver>postgresql-driver</driver>
    <security>
      <user-name>username</user-name>
      <password>password</password>
    </security>
  </datasource>
</datasources>

But Where i'm Stuck is : I'm Unable to insert the Data Inot the Database! It is raising an error as

ERROR: relation "hibernate_sequence" does not exist Position: 17 

I need A Help To Configure It .. I tried in MANY ways

Answer 1

I dont know if you still need help with this but I encounted similar error when deploying my application to the Openshift.

First I connected over SSH to openshift console. Then I ran psql (you can run psql on your host from $POSTGRES_HOME/bin/psql ) with credentials for my postgres connection and used \\ds and \\dt to determine that hibernate_sequence was a table and not a sequence.

So I dropped it: DROP TABLE hibernate_sequence;

And recreated it as a sequence: CREATE SEQUENCE hibernate_sequence;

Answer 2

For the Error Raised as: ERROR: relation "hibernate_sequence" does not exist Position: 17

i had created a SEQUENCE as Suggested by @Martin Nuc .

To Check Whether there is a Sequence in the Database or not use \\ds : Lists the Sequences in the database.

CREATE SEQUENCE hibernate_sequence;

Then i had raised with few more errors like -> Type Cast like things then after Clearing those Errors It Worked ! Finally :-)

Thanks for the Support Every1 :)

Answer 3

Alternatively you can also add @Generator instead of being auto, you can add sequence and specify a sequence generator that is used by PostGre which is ${table_name}_${pk}_seq.

Nevertheless, One draw back of doing this is to making your app tightly coupled to sequences.

Another strategy is to make hibernate create that hibernate_sequence if you force it to create DDL.
