5-calling stored procedures.and pl/sql functions in adf

in my previous blog i explained exception handling. now i will explain calling stored procedure.

in appmoduleimpl create method that named "addInformationMessageTest" .

public void addInformationMessageTest(String message, String cause)
  {
    DBTransaction trans = getDBTransaction();

    try
    {
      System.out.println("sd" + message);
      String plsql = "BEGIN eklesyslog(?,?,?); END;";

      CallableStatement stmt = trans.createCallableStatement(plsql, 0);
      stmt.setString(3, cause);
      stmt.setString(2, message);
      stmt.setString(1,
                     ADFContext.getCurrent().getSecurityContext().getUserName());
      stmt.execute();
      stmt.close();
      trans.commit();

    }
    catch (SQLException e)
    {
      if (trans != null)
      {
        System.out.println("2");
        trans.rollback();
      }
      System.out.println("23");
      throw new JboException(e);
    }
  }

import oracle.jbo.JboException;
import oracle.jbo.Session;
import oracle.jbo.server.ApplicationModuleImpl;
import oracle.jbo.server.DBTransaction;
import oracle.jbo.server.ViewLinkImpl;
import oracle.jbo.server.ViewObjectImpl;
import java.sql.CallableStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Types;
import oracle.jdbc.OracleTypes;

sample using function

public String BirimArmonizeDegisti(String armonizebirimbir, String armonizebirimiki, String cnbirimbir,
                           String cnbirimiki, String cnnumber)
  {
    CallableStatement cs=null;

    try{

    cs=getDBTransaction().createCallableStatement("begin ? := ISLEM_CARPAN_BUL(?,?,?,?,?); end;",0);

     cs.registerOutParameter(1, Types.VARCHAR);

      cs.setString(6, cnnumber);
      cs.setString(5, cnbirimiki);
      cs.setString(4, cnbirimbir);
      cs.setString(3, armonizebirimiki);
      cs.setString(2, armonizebirimbir);

    cs.executeUpdate();

    return cs.getString(1);

    }catch(SQLException e){

    throw new JboException(e);
    
  }
  }

after this process you wil see this methods in datacontrols section.
drag method your page and use it.
sample using method binding.

BindingContainer bindings = getBindings();
    OperationBinding operationBinding =
      bindings.getOperationBinding("getDataGrupSeviye");
    operationBinding.getParamsMap().put("madde", madde);
    operationBinding.getParamsMap().put("ikili", ikili);
   operationBinding.execute()

4-exception handling and logging in adf

create a class and extend it from DCErrorHandlerImpl. overriding getDisplayMessage and reportException enough for exception handling.

package view;

import java.util.Map;

import javax.faces.application.FacesMessage;
import javax.faces.context.FacesContext;

import oracle.adf.model.BindingContext;
import oracle.adf.model.binding.DCBindingContainer;
import oracle.adf.model.binding.DCErrorHandlerImpl;

import oracle.binding.OperationBinding;


public class CustomErrorHandler extends DCErrorHandlerImpl 
{
    public CustomErrorHandler() 
    {
        super(true);//test
    } 
    @Override
    public String getDisplayMessage(BindingContext ctx, Exception th) 
    {
      FacesContext ctx3 = FacesContext.getCurrentInstance();
      FacesMessage fm = new FacesMessage(FacesMessage.SEVERITY_INFO, "Teknik hata", th.getLocalizedMessage());
      ctx3.addMessage(null, fm);
      return super.getDisplayMessage(ctx, th);
    }

    @Override
    public void reportException(DCBindingContainer dCBindingContainer, Exception exception) 
    {
      BindingContext bindingContext = dCBindingContainer.getBindingContext();
      DCBindingContainer templateBindingContainer = bindingContext.findBindingContainer("view_templateMasterPageDef");
      String error = getDisplayMessage(dCBindingContainer.getBindingContext(), exception);
      OperationBinding operationBinding = templateBindingContainer.getOperationBinding("addInformationMessageTest");
      Map params = operationBinding.getParamsMap();
      params.put("cause", exception.getCause());
      params.put("message", exception.getMessage());
      operationBinding.execute();
      //super.reportException(dCBindingContainer, exception);
    }
    /**
     * Local method and not used outside
     * @param warning
     * @return
     */
    
  }

in databinding.cpx

in your masterpage bind method "addInformationMessageTest" to send exception to db or whatever .

i will explain another post using stored procedure and functions in adf.

3-adf security. (with ldap and database provider from weblogic)

sample login method like this.

package MBeans;

import java.io.IOException;

import javax.faces.application.FacesMessage;
import javax.faces.context.FacesContext;

import javax.security.auth.Subject;
import javax.security.auth.callback.CallbackHandler;
import javax.security.auth.login.FailedLoginException;
import javax.security.auth.login.LoginException;

import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import oracle.adf.model.BindingContext;
import oracle.adf.view.rich.component.rich.input.RichInputText;

import oracle.binding.BindingContainer;

import weblogic.security.SimpleCallbackHandler;
import weblogic.security.services.Authentication;

import weblogic.servlet.security.ServletAuthentication;


public class LoginBean
{
  private RichInputText txtUserName;
  private RichInputText txtPassword;

  public LoginBean()
  {
  }

  public BindingContainer getBindings()
  {
    return BindingContext.getCurrent().getCurrentBindingsEntry();
  }

  public String SubmitLogin_action()
  {
    String un = "";
    String pws = "";
    byte[] pw = null;
    try
    {
      un = (String) txtUserName.getValue();
      pws = (String) txtPassword.getValue();
      pw = pws.getBytes();
    }
    catch (Exception ex)
    {
      System.out.println(ex);
    }


    FacesContext ctx = FacesContext.getCurrentInstance();
    HttpServletRequest request =
      (HttpServletRequest) ctx.getExternalContext().getRequest();
    CallbackHandler handler = new SimpleCallbackHandler(un, pw);
    try
    {
      //login i?lemini ldap üzerinden gerçekle?tiriyor
      Subject mySubject = Authentication.login(handler);
      System.out.println("ldap");
      if (mySubject != null)
      {
        String un1 = un;
        String pwscakma = un;
        byte[] pwcakma = pwscakma.getBytes();
        //login i?lemi ldap üzerinden gerçekle?iyor ise db den roller için bir daha login oluyor
        CallbackHandler handler2 = new SimpleCallbackHandler(un1, pwcakma);
        Subject mySubject2 = Authentication.login(handler2);
        System.out.println("db");
        System.out.println(mySubject.getPrincipals());
        System.out.println(mySubject2.getPrincipals());
        ServletAuthentication.runAs(mySubject2, request);
        ServletAuthentication.generateNewSessionID(request);
        //db den contexte selam

        //BindingContainer bindings = getBindings();
        //OperationBinding operationBinding =
        //bindings.getOperationBinding("setContext");
        //operationBinding.getParamsMap().put("kullaniciad", un1);
        //operationBinding.execute();

        //yönlendiriliyor
        String loginUrl =
          "/adfAuthentication?success_url=/faces/WepPages/Welcome.jspx";
        HttpServletResponse response =
          (HttpServletResponse) ctx.getExternalContext().getResponse();
        sendForward(request, response, loginUrl);
      }
    }
    catch (FailedLoginException fle)
    {
      fle.printStackTrace();
      FacesMessage msg =
        new FacesMessage(FacesMessage.SEVERITY_ERROR, "Yanl?? Kullan?c? ad? veya parola?",
                         "Yanl?? Kullan?c? ad? veya parola");
      ctx.addMessage(null, msg);
    }
    catch (LoginException le)
    {
      reportUnexpectedLoginError("LoginException", le);
    }
    return null;
  }

  private void sendForward(HttpServletRequest request,
                           HttpServletResponse response, String loginUrl)
  {
    FacesContext ctx = FacesContext.getCurrentInstance();
    RequestDispatcher dispatcher = request.getRequestDispatcher(loginUrl);
    try
    {
      dispatcher.forward(request, response);
    }
    catch (ServletException se)
    {

    }
    catch (IOException ie)
    {

    }
    ctx.responseComplete();

  }

  private void reportUnexpectedLoginError(String string, LoginException le)
  {
    FacesMessage msg =
      new FacesMessage(FacesMessage.SEVERITY_ERROR, "Giri? Esnas?nda Beklenmeyen bir hata olu?tu",
                       "Giri? Esnas?nda Beklenmeyen bir hata olu?tu (" +
                       string + "), Detaylar için Loglara bak?n?z");
    FacesContext.getCurrentInstance().addMessage(null, msg);
    le.printStackTrace();

  }

  public void setTxtUserName(RichInputText txtUserName)
  {
    this.txtUserName = txtUserName;
  }

  public RichInputText getTxtUserName()
  {
    return txtUserName;
  }

  public void setTxtPassword(RichInputText txtPassword)
  {
    this.txtPassword = txtPassword;
  }

  public RichInputText getTxtPassword()
  {
    return txtPassword;
  }
}

for using db or ldap or both of them for authantication. you must define provider in weblogic.

here is the some sample usage of security context.

in java

ADFContext.getCurrent().getSecurityContext().getUserName();

ADFContext.getCurrent().getSecurityContext().isUserInRole();

in jspx

2-adf custom css skinning

create a xml file with name "trinidad-skins.xml" in in WEB-INF

register skin name in trinidad-config.xml

create a css file in defined place and use your custom css.


.AFDefaultFontFamily:alias {font-family: Verdana}.AFDefaultFont:alias {font-size: 16px}

use skin selectors.

hope this link helpful for you.

1-create pagetemplate, role based dynamic menu,page navigation

after creating template. insert a panelstrechlayout and configure for menu, banner, indicator,etc. we are using pagetemplates for inheritable content and actions. for example banner and menu or username info.

  
  
    
      
        templateMaster
        
          center
          center
        
      
    
    
      
        
          
            
          
                
                
                
                
          
            
          
          
            
          
          
        
      
      
        
          
            
          
        
      
    
  

below code show you; for creation role based menu using MenuBean.initMenu method and for logout dologout.

public class MenuBean
