1>jsf页面js调试，手动添加debugger调试
方案：在页面中添加debugger,然后打开“开发者工具”（必须打开），直接运行页面自动跳转到debugger处。
2>jdeveloper使用svn版本控制，修改后版本控制异常
方案：使用jdeveloper集成的svn版本进行控制，经常出现版本控制异常，比如修改了几个问题，查看版本变动的时候
发现以前添加的文件都没有版本了，方法重新启动jdeveloper
3>jdeveloper使用svn版本控制,修改文件后查看挂起的更改，发现没有记录
方案：打开任意一个jdeveloper中的项目，然后再查看挂起的更改。
4>jdeveloper开发过程中，调试和运行可能突然中断，然后点击页面运行或调试，进入页面后直接卡死，紧接着weblogic直接终止运行或调试。
再次运行或是调试，weblgici始终无法启动，
方案：run>start server instance，先运行weblogci,然后再选择页面点击运行
5>无法验证事务处理中的所有行
运行项目报错：
javax.faces.el.EvaluationException: oracle.jbo.TxnValException: JBO-27023: 无法验证事务处理中的所有行。
出错原因：提交的字段的值没有通过验证
比如说：字段的长度过长，类型不匹配
注意：如果对数据库中的字段做修改，要与eo同步更改。
6>jdeveloper快捷键
ctrl+enter：输入sop然后按ctrl+enter，输出 System.out.println()
ctrl+enter：直接输入ctrl+enter,出来流程控制的智能提示
ctrl+j：删除本行
shift+enter：换行
ctrl+shift+上下方向键：向上或向下移动当前行代码
ctrl+shift+空格键：上下文智能提示
shift+alt+f：格式化
7>通用类ADFUtils和JSFUtils

8>在jsf页面绑定的Managed Bean中引用am
在bean中获取am，在对应的jsf页面中必须有注册，否则返回空
ADFUtils.getApplicationModuleForDataControl("AppModuleAMDataControl");
9>jsf页面跳转，十一adf的link标签,设置destination属性
<af:link text="link 1" destination="" id="l1"/>
