Enabling "Contact List" sample application on Oracle ---------------------------------------------------- Key: JBSEAM-1805 URL: http://jira.jboss.com/jira/browse/JBSEAM-1805 Project: JBoss Seam Issue Type: Feature Request Components: Examples Affects Versions: 2.0.0.BETA1 Environment: OS: Windows Vista 6.0,x86 Database: Oracle Database 10g Express Edition Release 10.2.0.1.0 - Production Java VM: Java HotSpot(TM) Server VM 1.5.0_11-b03,Sun Microsystems Inc. Seam: jboss-seam-2.0.0.BETA1 Reporter: Ali Sadik Kumlali Priority: Optional Contact List sample application does not run against Oracle out-of-the-box. So I made some changes and managed it to run on Oracle. Since many enterprise developers must go with Oracle, I wanted to share the steps I followed through the way. Hope I didn't miss the point and this work helps someone else. Regards, Ali Sadik Kumlali -------------------- - Created a user, SEAM, and granted required privileges to it [1] - Created jboss-seam-contactlist-ds.xml file which defines a datasource whose jndi-name is ContactlistDS - Put the jboss-seam-contactlist-ds.xml file under resources folder of the sample - In persistence.xml, changed jta-data-source definition DefaultDS to ContactlistDS - Since Oracle considers the word "COMMENT" as reserved, it doesn't allow a table named "COMMENT" [2]. So, in Comment.java, I added @Table(name = "T_COMMENT") annotation below the @Entity. Thus, I let the Seam map Comment bean to T_COMMENT table. - To preserve consistency, I did the same for Contact.java. - import.sql cannot be used as is, since it doesn't have ID column filled a valid value[3]. So, I - Added sequence generator annotations in Contact.java and Comment.java as follows. Thus guaranteed the Seam to create the required sequences on start-up. @Id @SequenceGenerator(name = "generator", sequenceName = "COMMENT_SEQ") @GeneratedValue(strategy = SEQUENCE, generator = "generator") private Long id; - Changed each line of import.sql as follows: insert into T_Contact ( id, firstName, ... ) values ( Contact_Seq.nextval, 'Jacob', ...)
