OAF常用语句

1          页面提示：

String userContent =pageContext.getParameter("HelloName");
String message = "Hello," + userContent + "!";
throw new OAException(message, OAException.INFORMATION);

2          中文乱码：

try {
    retStr = new String(str.getBytes("ISO-8859-1"), "gb2312");
} catch (UnsupportedEncodingException e) {
    OAException.wrapperException(e);
}

3          String转换为Number注意要引进：

import oracle.jbo.domain.Number;
new Number(Integer.parseInt(String)); 

4          动态增加样式：

CSSStyle style = new CSSStyle();
style.setProperty("font-color", "#FFFFCC;");
webBean.findChildRecursive("DemandQty").setAttributeValue(INLINE_STYL   E_ATTR, style);

5          增加删除时的对话框提示：

AImageBean delAptitude =(OAImageBean)webBean.findChildRecursive("delAptitude");

String str =null;
String  javaStr =null;
if(delAptitude!=null){            
    try {
        str = new String("是否要删除该条认证信息？备注为：");
        str = new String(str.getBytes("ISO-8859-1"), "gb2312");                 
    } catch (UnsupportedEncodingException e) {

    }

//假设图标列控件的ID为：Y_REMARK   备注列控件的ID为：delAptitude
delAptitude.setOnClick("javascript.:var idStr = this.id; 

var remarkidStr = idStr.replace('delAptitude','Y_REMARK'); 
var remarktext = document.getElementById(remarkidStr);
if(remarktext == undefined){
    remarkidStr = idStr.replace('delAptitude','N_REMARK');         
    remarktext = document.getElementById(remarkidStr);
}

var str ='"+str+"';
var str2=remarktext.innerText;
var str3=str.concat(str2);
if(!confirm(str3)){ 
    return false ;
};  //注意在此处要返回flase
}  

6          远程调用的参数传递：

Serializable[] Parameters = {SearchLogonName,SearchUserName}; //创建变量数组
am.invokeMethod("UserQuery",Parameters); //调用AM方法UserQuery

7          条件拼凑：

public void initQuery(String SearchLogonName,String SearchUserName)

{

    StringBuffer WhereCluse = new StringBuffer(); //新定义一个WHERE条件的对象

    Vector Parameters = new Vector(2);

    int CluseCount = 0;

    int BindCount = 0;

    this.setWhereClauseParams(null);//以上是给对象初始化

    //保存LOGONNAME

    if ((SearchLogonName != null) && (!("".equals(SearchLogonName.trim()))))

    {

      WhereCluse.append("LOGON_NAME = :"); //增加一个字符串

      WhereCluse.append(++BindCount);

      Parameters.addElement(SearchLogonName);// 给BindCount赋值  用于判断

      CluseCount++;

    }

    //保存USER_NAME

    if ((SearchUserName != null) && (!("".equals(SearchUserName.trim()))))

    {

      if (CluseCount > 0)

      {

        WhereCluse.append(" AND ");   //拼SQL语句

      }

      WhereCluse.append("USER_NAME = :");

      WhereCluse.append(++BindCount);

      Parameters.addElement(SearchUserName);

      CluseCount++;

    }

    this.setWhereClause(WhereCluse.toString());

    if (BindCount>0)

    {

      Object[] Params = new Object[BindCount];

      Parameters.copyInto(Params);

      setWhereClauseParams(Params);//给WHERE条件赋值

    }

  }

8          页面跳转：

String userid = pageContext.getParameter("userid");//获取UserId
HashMap params = new HashMap(1);//创建HashMap对象
params.put("userid",userid);//给参数赋值

//跳转到修改页面，同时传递参数过去

pageContext.setForwardURL("OA.jsp?page=/oracle/apps/sie/lesson/update/webui/UpdateUserPG",
　　　　　　　　　　　　　　　　null,
　　　　　　　　　　　　　　　　OAWebBeanConstants.KEEP_MENU_CONTEXT,
　　　　　　　　　　　　　　　　null,params,true, // Retain AM
　　　　　　　　　　　　　　　　OAWebBeanConstants.ADD_BREAD_CRUMB_YES,
　　　　　　　　　　　　　　　　OAWebBeanConstants.IGNORE_MESSAGES);

9          新建时序列赋值：

public void create(AttributeList attributeList)
{
    super.create(attributeList);
    //修改给UserId赋值，获取序列号
    Number new_user_id = this.getOADBTransaction().getSequenceValue("OAF_EXM_USER_S");
    setUserId(new_user_id);
}

10       删除遍历：

------------------------版本一-----------------------------

public void deleteUser()

{

    OAViewObjectImpl vo =getUserSummaryVO1();

    UserSummaryVORowImpl row = null;

    int fetchedRowCount = vo.getFetchedRowCount(); //可用getRowCount();

    RowSetIterator deleteIter = null;

    try

    {

      deleteIter = vo.createRowSetIterator("deleteIter");

      if (fetchedRowCount > 0)

      {

        deleteIter.setRangeStart(0);

        deleteIter.setRangeSize(fetchedRowCount);

        while (deleteIter.hasNext())

        {

          row = (UserSummaryVORowImpl)deleteIter.next();

          System.out.print(row.getSelectFlag());

          if (“Y”. equals(row.getSelectFlag()))

          {

               row.remove();

          } 

        }

        getTransaction().commit();

      }

    }

    finally

    {

      if (deleteIter!=null)

      {

        deleteIter.closeRowSetIterator();

      }

    }

}

---------------------版本二-----------------------------------

private void deleteComment(int article_id)
{
    CommentVOImpl vo=(CommentVOImpl)getCommentVO1();
    CommentVORowImpl row = null;
    row=(CommentVORowImpl)vo.first();
    while(row!=null){
        Number primaryKey = row.getArticleId();
        if (primaryKey.compareTo(article_id) == 0) {
           row.remove();
　　　　    getTransaction().commit();
      }         

      if(vo.hasNext()) 
            row=(CommentVORowImpl)vo.next();
      else 
            break;
      }   
}

11       事务开和关：

――事务新建

TransactionUnitHelper.startTransactionUnit(pageContext, "createPlanTxn"); //开启事务

――事务关闭

if (TransactionUnitHelper.isTransactionUnitInProgress(pageContext, "createUserTxn", false)) //这里是用到一个令牌效果，如果执行了从新建页面回退到此页面，才执行如下操作。判断是否有令牌

    {     

      am.invokeMethod("cancel");    //调用AM 的cancel方法

      TransactionUnitHelper.endTransactionUnit(pageContext, " createUserTxn "); //撤消创建事务

    }

－－处理浏览器回退

//初始化加载页面，检查是否通过浏览器回退按钮进入本页面，如果是，则报警提示用户

if (!pageContext.isBackNavigationFired(false))

{

  //正常进入创建用户页面，申明创建用户事务

      TransactionUnitHelper.startTransactionUnit(pageContext, " createUserTxn ");

      //注册一个“createUserTxn”事务

     if (!pageContext.isFormSubmission())//判断是否提交

     {

       OAApplicationModule am = pageContext.getApplicationModule(webBean);

       am.invokeMethod("newUser");//调用AM的“newUser”方法

      }

    }

    else

{

 //浏览器回退钮进入，报异常信息

      if (!TransactionUnitHelper.isTransactionUnitInProgress(pageContext, " createUserTxn ", true))

      {

        OADialogPage dialogPage = new OADialogPage(NAVIGATION_ERROR);

        pageContext.redirectToDialogPage(dialogPage); //显示错误信息

      }

    }

12       取消，应用，增加：

//数据库的回滚

public void cancel ()

  {

    Transaction Txn = getTransaction();//创建对象

    if (Txn.isDirty())//检查是否脏数据

    {

      Txn.rollback();//执行回滚

    }

  }

//数据库提交

public void apply () {

     this.getDBTransaction().commit();//执行提交操作

  }

//创建新用户

public void createNewUser()

 {

   UserVOImpl vo = (UserVOImpl)getUserVO1();//获取VO

    vo.setMaxFetchSize(0);

    vo.executeQuery();//首先必须执行VO

Row row = vo.createRow();//创建一个新行

    vo.insertRow(row);//将新创建的行加入到VO里

    row.setNewRowState(Row.STATUS_INITIALIZED);//给创建的新行赋类型

  }

13       删除跳转页面提示：

String ctmCode = pageContext.getParameter("ctmcode");

      String ctmName = pageContext.getParameter("ctmname");

      String str=new String("是否确定要删除此客户信息(");

      String str2=new String(")?");

      try{

        str=new String(str.getBytes("ISO-8859-1"),"gb2312");

        str=str+ctmCode+"  "+ctmName+new String(str2.getBytes("ISO-8859-1"),"gb2312");

      }catch(Exception e){}

      OAException mainMessage = new OAException(str);

 

      OADialogPage dialogPage = new OADialogPage(OAException.WARNING, mainMessage, null, "", "");

 

      String yes = pageContext.getMessage("AK", "FWK_TBX_T_YES", null);

      String no = pageContext.getMessage("AK", "FWK_TBX_T_NO", null);

 

      dialogPage.setOkButtonItemName("DeleteYesButton");

      dialogPage.setOkButtonToPost(true);

      dialogPage.setNoButtonToPost(true);

      dialogPage.setPostToCallingPage(true);

      dialogPage.setOkButtonLabel(yes);

      dialogPage.setNoButtonLabel(no);

      java.util.Hashtable formParams = new java.util.Hashtable(1);

      formParams.put("id", id);

 

      formParams.put("ctmcode", ctmCode);

      formParams.put("ctmname", ctmName);

      dialogPage.setFormParameters(formParams);

  

      pageContext.redirectToDialogPage(dialogPage);

    }

    else if (pageContext.getParameter("DeleteYesButton") != null)

    {

      String id = pageContext.getParameter("id");

      String ctmCode = pageContext.getParameter("ctmcode");

      String ctmName = pageContext.getParameter("ctmname");

      Serializable[] parameters = { id };

      am.invokeMethod("DeleteCtmId",parameters);//调用AM方法删除 

 

      String str=new String("已删除客户信息(");

      String str2=new String(")");

      try{

        str=new String(str.getBytes("ISO-8859-1"),"gb2312");

        str=str+ctmCode+"  "+ctmName+new String(str2.getBytes("ISO-8859-1"),"gb2312");

      }catch(Exception e){}

      OAException message = new OAException(str,OAException.WARNING);

 

      pageContext.putDialogMessage(message);

    }

14       调用存储过程：

  int user_id = Integer.valueOf(pageContext.getParameter("user_id"));

        int org_id = Integer.valueOf(pageContext.getParameter("org_id"));

        int mfg_org_id = Integer.valueOf(pageContext.getParameter("mfg_org_id"));

        int po_line_id = Integer.valueOf(pageContext.getParameter("po_line_id"));

        int po_head_id = Integer.valueOf(pageContext.getParameter("po_head_id"));

        int resp_Id = Integer.valueOf(pageContext.getParameter("resp_Id"));

        int resp_appl_id = Integer.valueOf(pageContext.getParameter("resp_appl_id"));

        System.out.println("--start----");

        String result =null;

        OAApplicationModule am = (OAApplicationModule)pageContext.getApplicationModule(webBean);

        OADBTransaction transaction = null;

        CallableStatement  stm =null;

        try{

           transaction = am.getOADBTransaction();

        String sql ="Begin oaf_receive_inv_pg.receive_inv( p_user_id => :1, "

                                                 +"org_id => :2 ,"

+"p_mfg_org_id=> :3,"

+"p_po_line_id=> :4,"

+"p_po_head_id=> :5,"

+"p_resp_Id=> :6,"

+"p_resp_appl_id=> :7,"

                                                 +"o_result =>:8 ); end;";

          stm = transaction.createCallableStatement(sql,1);

          stm.setInt(1,user_id);

          stm.setInt(2,org_id);

          stm.setInt(3,mfg_org_id);

          stm.setInt(4,po_line_id);

          stm.setInt(5,po_head_id);

          stm.setInt(6,resp_Id);

          stm.setInt(7,resp_appl_id);

          stm.registerOutParameter(8, 12);

          stm.execute();

          result = stm.getString(8);

          System.out.println("end:"+result);

        }catch(Exception exception){

            exception.printStackTrace();

        } finally {

            try {

                if (stm != null) stm.close();

            } catch (Exception exception) {

                exception.printStackTrace();

            }

        }

}

15       绑定下载控件，实现文件名动态改变：

OAMessageFileUploadBean  ubean = (OAMessageFileUploadBean)webBean.findChildRecursive("N_ARRACH");

 if(ubean != null){

     OADataBoundValueViewObject kk = new OADataBoundValueViewObject(ubean,"AttachmentFilename");

          ubean.setAttributeValue(DOWNLOAD_FILE_NAME,kk);

    }

 

16       日期转换：

public String paseDate(String needByDate) {

   SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");

   String mDateTime ="";

   if(!"".equals(needByDate.trim())){

         mDateTime = formatter.format(new java.util.Date(needByDate));

      }

        return mDateTime;

  }

 

17　　遍历VO：

方法一：

OAViewObject vo = (OAViewObject)am.findViewObject("XXVO");
Row lineVO=vo.first();
while ( lineVO != null) {
    //TODO
    lineVO = vo.next();
}

方法二：

for (Row row2 = vo.first(); row2 != null; row2 = vo.next()) {
   //meaning = (String)row2.getAttribute("Meaning");
   //TODO    
}
