Dive into Technology: ADF Validator

About Java, Oracle ADF, Oracle EBS, JDeveloper, Google Techs, etc. 实际应用中经常遇到对业务相关的数据进行Validate的情况。比如对输入数据进行格式限制/范围限制等。ADF为开发人员提供了相对灵活的解决方案。这里提供了几种Validator的不同实现方式。 65288;下述均使用Oracle XE自带的HR示例中Employees表作为示例表). 首先,ADF框架中所有的Validator默认都使用EO级别的Validator。EO层次可以设置Entity级别的Validator或Attributes级别的Validator。 选择需要的Validator Rule Type,写入相应的验证规则后,即可在Failure Handling中写入验证失败的抛出消息。在此处设置的消息将写入资源文件中。 最后,当VO被拖入页面时,对应控件将自动包含一个 f:validator 子控件,其绑定为EO层次的Validator。 Public class testValidator implements Validator {.

Oracle Application Development Framework是Oracle Fusion中间件体系架构的重要组成部分,是一个端到端的J2EE开发框架。ADF框架通过提供实用级别的基础架构服务和虚拟的声明式开发体验,从而简化了J2EE开发。不同于其他开源开发框架,Oracle ADF提供了一个包含Business Service、Model、View、Controller的完整MVC实现,在企业应用架构的每一个层次都提供了支持。 12 Oracle ADF 11g框架简介. 最简单的View层实现即为一个包含用户界面组件的页面,并允许该页面中的组件调用Model层中的方法。Oracle ADF为了提高View层的重用程度,引入了如下结构体系。 在常的应用场景下,可以通过Page Template构建某应用的页眉、页脚、导航栏...Region是Fusion架构体系中...

Dive into Technology: 解决ORA-00020错误
http://eleven-china.blogspot.com/2009/04/ora-00020.html
About Java, Oracle ADF, Oracle EBS, JDeveloper, Google Techs, etc. 项目上使用的Oracle服务器经常出现无法登陆的情况,尝试查看数据库dump文件,没有发现在无法登陆时的报错信息,使用SecureCRT连接服务器登录sqlplus时出现错误" ORA-00020. Maximum number of processes (150) exceeded",解决方法如下:. 开始时怀疑数据库死锁,通常这种情况下可以通过查询下列表/视图,杀死死锁的进程解决:. 通过查询V$SESSION视图,发现连接总量已达到上限150,由于在做Oracle ADF开发,该OracleDB作为开发数据库,连接较多属于允许范围内,遂增大最大连接数,修改对应init.ora文件中"procdsses=150",重启DB。 SQL show parameter processes; / 查看processes连接数设置.

Dive into Technology: Oracle ADF VO排序及VO的查询模式
http://eleven-china.blogspot.com/2009/04/oracle-adf-vovo.html
About Java, Oracle ADF, Oracle EBS, JDeveloper, Google Techs, etc. 常规应用中,当需要使用Table向终端用户展示数据时,Table中数据的显示排序一致性极大程度的影响到了客户体验。通常希望诸如多次查询结果显示顺序相同、插入数据在原数据上方等的实现。 ADF为开发人员提供了两种级别的排序,即数据库级别的排序及内存级别(In-Memory)的排序。需要同时使用这两种排序法,才能取得合适的排序效果。 编辑VO的Query,设置Order by字段,这里设置Manager作为排序字段. 需要注意的是,这里的排序只是针对从数据源选取数据时的排序,当对VO进行插入/删除操作时,修改并不会立即Commit至数据库,而是存储在EO/VO中,这就导致这种排序法对于不在数据库中存在实体行的数据是无效的,也是需要使用In-Memory排序方式的原因。 VO的查询模式(View Object's SQL Mode).

Dive into Technology: ADF实现树状查询
http://eleven-china.blogspot.com/2009/04/adf.html
About Java, Oracle ADF, Oracle EBS, JDeveloper, Google Techs, etc. 最近项目遇到要用start with connect by做树状查询,即:选择一个部门老大,要把老大下面的小老大和各个小弟全查出来,ADF貌似没有提供这类查询(至少我没发现,呵呵,如果有那就更好了,可以不给下面看了),这个办法不一定最好,但是,绝对可以实现,. 2 1)如果你能知道你要查询的最顶层user的userid,那么你可以这样建VO,绑定一个参数p userId,默认值就是最顶层的user的userid;VO上面的sql为:. Select * from user start with userid=:p userId connect by prior parent id = user id. 2 2)如果你不知道你要查询的最顶层user的userid,那么你可以这样建VO,绑定一个参数p userId,默认值就是最顶层的user的userid;VO上面的sql为:. 订阅: 帖子评论 (Atom).
