How to read a parameter from properties file by shell script ?

I used ‘source’ syntax to called the parameter from property file.

1. create your directory on your linux OS environment.
– this <mydir> you need to change.

/<mydir>/call_dir/
call_dir.sh
/<mydir>/call_dir/config/
config.properties

/<mydir>/call_dir/logs/
log.txt

2. source bash file – ‘ call_dir.sh ‘

base_dir=/mydir/call_dir
config_dir=${base_dir}/config

# use source command to read the parameter key in properties
if [ -f ${config_dir}/config.properties ];then
source ${config_dir}/config.properties
else
MESSAGE=”Script END”
echo “$MESSAGE”
fi
echo “Log directory $LOG_DIR”

3. properties file config.properties
– values:
LOG_DIR=<mydir>/logs/logs.txt

Thread in Java.

1. What is Thread?
 1.a. Thread is a Light-weight ,its allow multiple activities within a single process.
 1.b. All treads of a process share the common memory space, The process of execution multiple threads simultaneously is known as multi-threading.

2. Non-Thread Program vs Thread Program

2.a. Example Non-Thread Program.

public class WithoutThread {

 // main method
 public static void main(String[] args) {
  // TODO Auto-generated method stub
  String str = “banana”;
  String str2 = “papaya”;
  
  ProcessClass proStr = new ProcessClass();
  proStr.IterateRandomValue(str);
  proStr.IterateRandomValue(str2);
}
}
class ProcessClass{
 public void IterateRandomValue(String itr){
  for (int i = 0; i < 5; i++) {
    System.out.println(i + ” ” + itr );
  }
   }
 }

OUTPUT in Console:
0 banana
1 banana
2 banana
3 banana
4 banana
0 papaya
1 papaya
2 papaya
3 papaya
4 papaya

Descriptions on without Thread class : without added thread class, it will execute the process one by one ( check the output program above, program banana will run first until its finish, and then, papaya program will be run ) – sequentially. the Process will taking longer time to finish the processing compare than extends Thread class or implements Runnable class.

2.b. Thread Program.

  • the Functions of Java Threads is to allow multiple activities within a single process.
  • To implement The Threads function we need to extends Thread Class or Implements Interface Runnable Class.

Example Program extend Thread class.

public class ThreadExample {
 //Main Thread
    public static void main(String[] args)
    {
     // TODO Auto-generated method stub
     String str = “banana”;
     String str2 = “papaya”;
     
     // First Thread
     ExtendThread firstThread = new ExtendThread(str);
     firstThread.start();
     
        //Second Tread
     ExtendThread secondThread = new ExtendThread(str2);
     secondThread.start();
    }

}

class ExtendThread extends Thread
{
 private String strNew;

 ExtendThread(String str) {
  strNew = new String(str);
 }

 @Override
 public void run() {
  for (int i = 0; i < 5; i++) {
   System.out.println(i + ” ” + strNew);
  }

 }
}

Output:
Starting Banana
Creating ..Papaya
Starting Papaya
Running..Banana
Thread : Banana,4
Running..Papaya
Thread : Papaya,4
Thread : Banana,3
Thread : Papaya,3
Thread : Banana,2
Thread : Papaya,2
Thread : Banana,1
Thread : Papaya,1

  • If we see the results for (papaya,1) and (Banana, 1) its actually run simultaneously

    Good Day!

    How to Use ServletOutputStream – for Servlet Download zip file into response Client?

    Description / Answer:

    • from the tomcat.apache.org lib descriptions – Provides an output stream for sending binary data to the client.
    • is an abstract class that the servlet container implements. Subclasses of this class must implement the java.io.OutputStream.write(int) method.
    • method that are regularly used are : .write() – writing what the client request and paste to servlet response client.
    • Its use to attached the Output Stream to download on browser.

    example program – Servlet Class :

    ServletOutputStream servletOutputStream = null;
    FileInputStream fileInputStream = null;
    filename = “documentInput.Zip“;

    try {
    File file = new File(“C://documents/temp/tempfile.zip“);
    fileInputStream = new FileInputStream(file);
    servletOutputStream = response.getOutputStream();

    // download using browser client – change to byte
    response.setContentType(“application/zip“);
    response.setContentLength((int)f.length());
    response.addHeader(“Content-Disposition“,”attachment;filename=\“” + filename + “\””);
    byte[] arBytes = new byte[32768];

    int count;
    while ((count = fileInputStream.read(arBytes)) > 0)
    {
    servletOutputStream.write(arBytes, 0, count);
    }

    }catch (IException e) {
    // TODO: handle exception
    } finally{
    servletOutputStream.flush();
    fileInputStream.close();
    }

    Adding the IBM MobilFirst SDK to Android Application – Hello World

    Good Day! & Happy New Year 2017 Gregorian Calendar

    1.) Create New Project in Android Studio. Select File > New Project.

    2.) Enter new Project, add the name for the project with the name of the package, example:

    New Project name : MyApp

    company domain : com.fndong.myApp

    3.) Then After created, adding the SDK into android MyApp Application.

    3.1) Add the sdk plugin mobilefirst android in build.gradle (Module:App).

    apply plugin: 'com.android.application'
    repositories{
        jcenter()
    }
    android {
        compileSdkVersion 23
        buildToolsVersion "25.0.2"
    
        packagingOptions {
            pickFirst 'META-INF/ASL2.0'
            pickFirst 'META-INF/LICENSE'
            pickFirst 'META-INF/NOTICE'
        }
    
        defaultConfig {
            applicationId "myapp.com.fndong.myapp"
            minSdkVersion 22
            targetSdkVersion 23
            versionCode 1
            versionName "1.0"
        }
        buildTypes {
            release {
                minifyEnabled false
                proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            }
        }
    }
    
    dependencies {
        compile 'com.ibm.mobile.foundation:ibmmobilefirstplatformfoundation:8.0.+'
        compile fileTree(dir: 'libs', include: ['*.jar'])
        testCompile 'junit:junit:4.12'
        compile 'com.android.support:appcompat-v7:23.4.0'
    }

    4.) Add the Permission and the Mobilefist UI activity in the AndroidManifest.xml.

    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
    • add inside tag <application…>
    <activity android:name="com.worklight.wlclient.ui.UIActivity" />

    5.) Running emulator – just go here android_page

    6.) Go to Run – app / (Shift+ F10) – then it will show your first Mobile App with Mobilefist SDK for Android.

    7. Add the registration of the application with mobilefirst server – and add the mfpclient.properties

    • using node.js prompt – set this command : mfpdev app register (must run the mobilefirst Foundation server 8.0 – for console first)
