Hi All,

  I'm new to Seam framework and trying my first example with below link

http://docs.jboss.org/seam/1.0.1.GA/reference/en/html/tutorial.html

  This example is working fine but I'd like to change persistence to sybase rather than jboss DefaultDS.

  Please find modified 'persistence.xml' file as below

<?xml version="1.0" encoding="UTF-8"?>
<persistence 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_1_0.xsd" 
             version="1.0">
             
   <persistence-unit name="userDatabase">
      <provider>org.hibernate.ejb.HibernatePersistence</provider>
      <!-- <jta-data-source>java:/MyApp</jta-data-source> -->
      <properties>
                 <property name="hibernate.dialect" value="org.hibernate.dialect.SybaseDialect"/>
         <property name="hibernate.connection.driver_class" value="com.sybase.jdbc3.jdbc.SybDriver"/>
         <property name="hibernate.connection.username" value="test"/>
         <property name="hibernate.connection.password" value="temp123"/>
         <property name="hibernate.connection.url" value="jdbc:sybase:Tds:testDB.org:2222/trial"/>

         <property name="hibernate.hbm2ddl.auto" value="update"/>
      </properties>
   </persistence-unit>
   
</persistence>

  After making this change and deploying register example on Tomcat 6.o throwing below error message

* CONTEXTS IN ERROR: Name -> Error

<UNKNOWN> -> ** UNRESOLVED Demands 'persistence.units:jar=jboss-seam-registratio
n.jar,unitName=userDatabase **

persistence.units:jar=jboss-seam-registration.jar,unitName=userDatabase -> java.
lang.RuntimeException: Specification violation [EJB3 JPA 6.2.1.2] - You have not
 defined a jta-data-source for a JTA enabled persistence context named: userData
base

  As per this error it is expecting 'jta-data-source', I don't know what to provide for this parameter.

  Can anyone please let me know, how to resolve this error. I'm deploying application on Tomcat 6.0 and I don't have any datasource configuration on this server...

  Thanks in advance.

Regards,
Sharath.
