          are you using some tools like seam-gen or JBoss Tools?

            check your projectName-dev-ds.xml


            You should have something like this:



            <datasources>
               
               <local-tx-datasource>
                  <jndi-name>yourProjectDatasource</jndi-name>
                  <connection-url>yourproperDatabaseUrlConnection</connection-url>
                  <driver-class>yourproperdriver. Forexamplecom.sybase.jdbc2.jdbc.SybDriver</driver-class>
                  <user-name>yourDatabaseUser</user-name>
                  <password>yourDatabasePassword</password>
                  <min-pool-size>1</min-pool-size>
                 <max-pool-size>20</max-pool-size>
                 <idle-timeout-minutes>15</idle-timeout-minutes>
                 <exception-sorter-class-name>ProperSorter. For example org.jboss.resource.adapter.jdbc.vendor.SybaseExceptionSorter</exception-sorter-class-name>
                 <type-mapping>ProperSorter. For example Sybase</type-mapping>
            
               </local-tx-datasource>
                
            </datasources>
            



            Both JBoss tools and seam gen helps you to generate and configure that file.
