Using JSTL in ADF Faces - By Frank Nimphius

The JavaServer Pages Standard Tag Library (JSTL) provides expressions for common web application functionalities. Though JavaServer Faces Expression Language (EL) is different from JSTL expressions, the two can be used in combination for functional for which it makes sense. For example, the table below lists JSTL expressions that operate on String values.

 

fn:contains() - Tests if an input string contains the specified substring.

 

fn:containsIgnoreCase() - Tests if an input string contains the specified substring in a case insensitive way.

 

fn:endsWith() - Tests if an input string ends with the specified suffix.

 

fn:escapeXml() - Escapes characters that could be interpreted as XML markup.

 

fn:indexOf() - Returns the index withing a string of the first occurrence of a specified substring.

 

fn:length() - Returns the number of items in a collection, or the number of characters in a string.

 

fn:replace() - Returns a string resulting from replacing in an input string all occurrences with a given string.

 

fn:startsWith() - Tests if an input string starts with the specified prefix.

 

fn:substring() - Returns a subset of a string.

 

fn:substringAfter() - Returns a subset of a string following a specific substring.

 

fn:substringBefore() - Returns a subset of a string before a specific substring.

 

fn:toLowerCase() - Converts all of the characters of a string to lower case.

 

fn:toUpperCase() - Converts all of the characters of a string to upper case.

 

fn:trim() - Removes white spaces from both ends of a string.

To use JSTL in Oracle ADF Faces component EL references, you need to add the JSTL namespace of the tags you want to reference. For the JSTL functions shown in the table above, you need to manually add the name space highlighted in red to the JSPX document or page fragment.

 

<jsp:root  
 xmlns:jsp="http://java.sun.com/JSP/Page" version="2.1"         
 xmlns:f="http://java.sun.com/jsf/core"         
 xmlns:h="http://java.sun.com/jsf/html"         
 xmlns:af="http://xmlns.oracle.com/adf/faces/rich"        
xmlns:fn="http://java.sun.com/jsp/jstl/functions">

 

The value expression below, referenced in an af:outputText component, displays the substring (first, second and third character) for a value read from the ADF binding layer.

 

<af:outputText value="#{fn:substring(bindings.employeeName.inputValue,1,3)}" id="ot7"/>

Using AT commands to send and read SMS

 

Introduction

 

 

This article discusses how to use AT commands to send and receive SMS. It can be used to create a PC application that send SMS from the phone. This kind of application is useful, for example, in automating test cases related to SMS.

 

Note that not all phones support all SMS AT commands. For example, some phones may support send command only and not support read command. See also links at the end of this article to find more about AT commands, including complete list of SMS AT commands on Nokia's GSM and WCDMA products.

Message Format

 

 

There are basically two modes to work with SMS, i.e.:

 

• PDU (Protocol Data Unit)
• Text mode.

 

A mobile phone internally uses PDU format. Developers normally uses text mode because it is easier to use. AT+CMGF is the command to set the mode.

 

AT+CMGF=0

 

sets the format to PDU mode.

 

AT+CMGF=1

 

sets the format to text mode.

 

AT+CMGF?

 

queries the current format.

 

 

Sending SMS

 

 

Although you can send SMS in PDU or text mode, it is easier to use text mode to type the message.

 

The following commands change the message format to text mode and send a text message.

 

AT+CMGF=1
OK
AT+CMGS="7789952010"
> Hello World<Ctrl>+<Z>
+CMGS: 44
 
OK

 

Note that <Ctrl>+<Z> has to be entered at the end of message to send the message.

 

 

Reading SMS

 

 

Use the following command to read the list of all messages on the phone:

 

AT+CMGL="ALL"
+CMGL: 123,"REC READ","+123456789"
Hello World
 
 
OK

 

Use the following command to read a message with has index of 123:

 

AT+CMGR=123
+CMGR: "REC READ","+17789975545","08/09/05,17:46:49-12"
Hello World
 
OK

AT Commands

 

What you should know

 

 

Different phones support different sets of AT commands. This means that a specific phone might not support all AT commands listed below. Currently there is no authoritative list available of supported AT commands by all phones.

 

Overview

 

 

AT commands are also known as Hayes AT commands. There are different views to understand the meanings of "AT". Some call it "Attention Telephone", whereas others interpret it as "Attention Terminal" commands.

 

AT commands allow giving instructions to both mobile devices and ordinary landline telephones. The commands are sent to the phone's modem, which can be a GSM modem or PC modem. This article focuses on AT commands on Nokia's GSM and WCDMA products only. Different manufacturers may have different sets of AT commands. Fortunately, many AT commands are the same. Mobile device manufacturers may also give attention to operators to allow or not to allow some commands on phones.

 

AT commands can be used for operations that are usually done from the keypad, for instance calling a number, sending, reading, or deleting an SMS, setting the SMSC number, looking for a GPRS access point, reading and deleting phonebook data, reading the battery status, reading the signal strength, and so on. When you want to make a PC-based application to interface a mobile phone using USB, IR, or Bluetooth, these commands are needed to communicate with mobile phones. Basically such commands are the application layer of MBUS or FBUS commands. Nokia provides an AT command set guide, where you can see the basic command syntax and the response of the command in various situations. See the Related Links section at the end of this article).

 

 

Using AT Commands with HyperTerminal

 

 

AT commands work on devices that have a built-in GSM modem. If there is one, you do not need to install virtual modem software on your PC. If you are using very old Nokia devices, you have to find out the DATA suite, not the PC Suite, for these devices (such as the Nokia 5110) to be able to use AT commands. This article focuses on mobile devices that have a built-in GSM modem.

 

To use AT commands:

 

• Connect the mobile phone to your PC in PC Suite mode using any available connection (Bluetooth, USB, or IR).

 

• Make sure that you have installed the correct GSM modem driver on your PC. You can check it from Control Panel | System | Hardware | Device Manager. Check the Modems section. If you see something like "Nokia XY USB Modem" or "Nokia XY Bluetooth Modem", the device has a built-in GSM modem. If you don't have it, go to the Nokia Web site and download the driver from the product page of your device.

• Right Click on Nokia N95 8GB USB Modem and find the port used by selecting the modem tab, in our case it is COM 4. Also it is good to test the modem by selecting Diagnostics | Query Modem, this will tell us if the modem is working properly.
• Open the HyperTerminal, which is a communication utility on Microsoft Windows OS. HyperTerminal is located in Start | Programs | Accessories | Communication.

 

• Create a new connection set on HyperTerminal and give a name to the connection.
• Select the port number by seleting drop down box "Connect using". In our case the port number is COM 4

 

Selectportatcommand.png

 

• You need to select some settings related to ASCII setup, To do select File | Properties | Settings (tab) | ASCII Setup

 

Asciisetup.png

 

• You may need to set some parameters, such as baud rate (for example, 9600), handshaking mode (Xon-Xoff), parity bit (default), and so on.

 

Hyperterminal settings.png

 

• Note that you also need to select the communication port on which your mobile has been connected. The port number can be found by right-clicking the modem item in Control Panel.

 

Controlpanel gsmmodem port.png

 

• After this, you can give the basic AT command. Simply type AT in the window and you will get the "OK" response.

 

Hyperterminal example.png

 

The above picture also shows how to dial a number using the ATD command. Note that there is a semi-colon (;) at the end of the phone number indicating that this is a voice call. If there is no semi-colon, a data call (CSD call) is will be performed.
