我一直试图从Seam论坛获得帮助，但徒劳无功

我正在尝试标题中提到的这个设置，但没有成功

我已将其全部正确安装，问题始于seam-gen

这是我的build.properties

/seam create project工作正常，但是当我尝试生成实体时，我得到了以下结果…

generate-model:
     [echo] Reverse engineering database using JDBC driver /home/rgoytacaz/postgresql-8.4-701.jdbc4.jar
     [echo] project=/home/rgoytacaz/workspace/Commerce
     [echo] model=com.atom.Commerce.model
[hibernate] Executing Hibernate Tool with a JDBC Configuration (for reverse engineering)
[hibernate] 1. task: hbm2java (Generates a set of .java files)

[hibernate] log4j:WARN Please initialize the log4j system properly.
[javaformatter] Java formatting of 4 files completed. Skipped 0 file(s).

这是第一个问题。我该如何解决这个问题？这是什么？我必须在eclipse中这样做。它成功了。

     [echo] Reverse engineering database using JDBC driver /home/rgoytacaz/postgresql-8.4-701.jdbc4.jar

[javaformatter] Java formatting of 4 files completed. Skipped 0 file(s).

然后我将seam gen创建的项目导入eclipse，并部署到JBoss 5.1。当我的服务器启动时，我注意到以下几点

03:18:56,405 ERROR [SchemaUpdate] Unsuccessful: alter table PostgreSQL.atom.productsculturedetail add constraint FKBD5D849BC0A26E19 foreign key (culture_Id) references PostgreSQL.atom.cultures
03:18:56,406 ERROR [SchemaUpdate] ERROR: cross-database references are not implemented: "postgresql.atom.productsculturedetail"
03:18:56,407 ERROR [SchemaUpdate] Unsuccessful: alter table PostgreSQL.atom.productsculturedetail add constraint FKBD5D849BFFFC9417 foreign key (product_Id) references PostgreSQL.atom.products
03:18:56,408 ERROR [SchemaUpdate] ERROR: cross-database references are not implemented: "postgresql.atom.productsculturedetail"*
03:18:56,408 INFO  [SchemaUpdate] schema update complete

问题2。什么是跨数据库引用？

这个怎么样

03:18:55,089 INFO  [SettingsFactory] JDBC driver: PostgreSQL Native Driver, version: PostgreSQL 8.4 JDBC3 (build 701)

问题3我在build.properties中说过要使用JDBC4驱动程序，我不知道seam为什么坚持使用JDBC3驱动程序。在哪里更改此设置？

当我进入并尝试浏览自动生成的CRUD UI时

我得到了这个错误读取com.atom.Commerce.action.ProductsList\u$$\ uJavassist\uSeam\u2类型上的'resultList'时出错

这就是我的服务器日志中显示的内容

03:34:00,828 INFO  [STDOUT] Hibernate: 
    select
        products0_.product_Id as product1_0_,
        products0_.active as active0_

Caused by: javax.persistence.PersistenceException: org.hibernate.exception.GenericJDBCException: could not execute query

问题4这里发生了什么？跨数据库引用？

谢谢您对我的任何问题的帮助。

您确实在Seam论坛（和）上收到了一些答案，但您没有跟进。总之，所有这些实际上都是由一个问题引起的：

作为Stuart Douglas，连接到PostgreSQL时不应该使用目录。若要解决此问题，请将属性文件中的属性“

hibernate.default\u catalog=PostgreSQL

”替换为属性“

hibernate.default\u catalog.null=

”，使文件如下所示：

...
model.package=com.atom.Commerce.model
hibernate.default_catalog.null=      # <-- This is the replaced property
driver.jar=/home/rgoytacaz/postgresql-8.4-701.jdbc4.jar
...

。。。
model.package=com.atom.Commerce.model
hibernate.default_catalog.null=#
