    Backups and migrations

    Ewen Fortune Newbie

      Hi,

      I have absolutely no experience of JBoss, I would like to know if it has any built in functionality for exporting a java webapp with database configuration and everything with a view to import later into another server. Along the lines of backup but to make the migration from one hosting provider to another.

      Can anybody help on this, the app in question is some java webapp that uses hibernate to connect to an Oracle database - since the only element I have any understanding of is the Oracle database I figure the easiest way to migrate would lay in the application server level.

      Cheers,

      Ewen

          The type of web app and database config you are describing could be packaged in several ways, only some of which I will mention.

          You could have a WAR file for the app itself and a *-ds.xml file for the data source. Moving the app to another JBOss AS instance involves simply copying the WAR and *-ds.xml files.

          You could package the WAR and *-ds.xml within an EAR file. Then there is only one file to copy. This also works well of you have EJBs.

              Do you change the database type?

              If not I suppose that this will be an issue with your EJB3 (JPA) POJO's.

              I might that the container work different and you must declare (annotate) the entity attribute to store it.

               

              Please provide a bit more information about the error, the entity and the related DB table.

                  The EntityManager try to map your text to int,

                  do you set the persistence.xml correct?

                       <property name="hibernate.dialect" value="org.hibernate.dialect.<your dialect>"/>

                  also this might help to analyze:

                        <property name="hibernate.show_sql" value="true" />

                        <property name="hibernate.format_sql" value="true" />

                   

                  Also you should set the 'org.hibernate' to logging level 'TRACE' to find out what happen.

                   

                  I suppose that the handling of @Lob will be different, does it work if you remove @Lob?

                      the problem was @Lob.. i remove from entities and everything works..!!!

                        That reinforce my assumption that the @Lob annotation will be handle different in the newer version of hibernate.

                        I suppose there is no drawback to use it like this, but test it for your app maybe the lenght will be a problem (but I don't think so)
