Hi!! I am new in all this world and I have problems with the Seam.
First, I am using an Oracle 9.2 DB. There are tables that have simple
primary-keys and others that have composite primary-keys. Other tables have
foreign-keys and a mix of primary and foreign keys.
I want to generate the entities corresponding to each table of my DB using
seam-gen. I create a project in Seam and then I type 'seam generate-entities'
from which I receive a successful build. The problem comes when I type 'seam
restart', I receive BUILD FAILED.
When I see inside my project I can see several generated files corresponding to
the tables in the DB. For example, I have this table:
table GRUPOS_USUARIOS
(
COD_GRUPOS_USUARIOS NUMBER(10) not null,
NOMBRE_GRUPOS_USUARIOS VARCHAR2(60) null,
primary key (COD_GRUPOS_USUARIOS)
)
seam-gen generates 3 files GrupoUsuarios.java, GruposUsuariosHome.java and
GruposUsuariosList.java.
And in other table that has a composite primary key:
table auditoria
(
fecha date not null,
cod_audit number(10) not null,
descripcion varchar2(256) not null,
aplicacion varchar2(64) not null,
equipo varchar2(16) not null,
primary key (fecha, cod_audit, equipo)
)
I get 4 files from generate-entities AuditoriaHome.java, Auditoria.java,
AuditoriaList.java and AuditoriaId.java.
When I do seam restart I receive this error among other:
[javac]
c:\DesarrolloJava\Workspace\Teldages\src\action\com\mydomain\Teldages\Auditori
aHome.java:26: isEmpty(java.lang.String) in org.jboss.seam.util.Strings cannot
be applied
to (java.util.Date)
[javac] if (Strings.isEmpty(getAuditoriaId().getFecha()))
Could anyone help me? Do I have to modify the reveng.xml file?
Thanks in advance.
