Call a PL/SQL Package

Question

Hi All,
I'm using ADF BC, JDev 11G.

Thanks in Advance, assistance will be appreciated.

Use a method like the following inside your AppModuleImpl file.
  public Integer myMethod(String pParam1, int pParam2) {
    int returnValue = 0;
    String selectDML = "{? = call pkg_name.pkg_function(?,?)}";
    CallableStatement statement = getDBTransaction().createCallableStatement(selectDML, 1);
    try {
      statement.registerOutParameter(1, Types.INTEGER);
      statement.setInt(1, returnValue);
      statement.setString(2, pParam1);
      statement.setInt(3, pParam2);
      statement.execute();
      returnValue = statement.getInt(1);
      statement.close();
      return returnValue;
    } catch (Exception ex) {
      throw new JboException(ex);
  }The above a example uses a pkg with 1 out and 2 in params, customize it to your needs.
Then you could use it inside a managed bean like follows:
  private int returnValue;
  public int getReturnValue() {
    ApplicationModule am =
      BindingContext.getCurrent().getDefaultDataControl().getApplicationModule();
    AppModuleImpl appModuleImpl = (AppModuleImpl)am;
    returnValue = appModuleImpl.myMethod("aString", 0);
    return returnValue;
  }Hope that helps.
