Installing the Java Software Developers Kit (SDK):

Sun has various bundled Java packages available for download: Java Standard Edition (SE), Java Runtime Environment (JRE), Software Development Kit (SDK), EE (Enterprise Edition), JavaFX, Netbeans (IDE) or just the bundle: Java SE and JDK development kit, used in this example. Note that the Java Runtime Environment (JRE) by itself is not for software development but only a JVM to run Java applications.

Download Java "Standard Edition" (SE) Software Developers Kit (SDK).

The Java "Enterprise Edition" with Glassfish application server is also available for Java web services development.


The installation of multiple versions of Java on different machines will require a ".bashrc" file which can locate the appropriate CLASSPATH.

Example file: $HOME/.bashrc
..
...

#
# Java
#
if [ -d /opt/java/latest ]
then
  PATH=/opt/java/latest/bin:$PATH
  export JAVA_HOME=/opt/java/latest
  export CLASSPATH=/opt/java/latest/lib/tools.jar:./
elif [ -d /opt/java/jdk1.6.0_01 ]
then
  PATH=/opt/java/jdk1.6.0_01/bin:$PATH
  export JAVA_HOME=/opt/java/jdk1.6.0_01
  export CLASSPATH=/opt/java/jdk1.6.0_01/lib/tools.jar:./
elif [ -d /usr/java/jdk1.6.0 ]
then
  PATH=/usr/java/jdk1.6.0/bin:$PATH
  export JAVA_HOME=/usr/java/jdk1.6.0
  export CLASSPATH=/usr/java/jdk1.6.0/lib/tools.jar:./
elif [ -d /usr/lib/jvm/jre-1.4.2-sun/bin ]
then
  PATH=/usr/lib/jvm/jre-1.4.2-sun/bin:$PATH
  export JAVA_HOME=/usr/lib/jvm/jre-1.4.2-sun
  export CLASSPATH=/usr/lib/jvm/jre-1.4.2-sun/lib/tools.jar:/usr/lib/jvm/jre-1.4.2-sun/lib/rt.jar:./
fi

...
..
                
Where the following soft link is typical: ln -s /opt/java/jdk1.6.0_01 /opt/java/latest
Must include "./" in CLASSPATH. This is necessary in 1.4.x and later.

Java SDK 1.6:

There is a choice of running 32 bit Java on a 32 bit or 64 bit Linux platform or running 64 bit Java on a 64 Linux bit platform.

There are three options offered for the download:

  1. compressed tar file: jdk-7u4-linux-x64.tar.gz
    Install:
    • cd /opt/java
    • tar xzf ~/Downloads/jdk-7u4-linux-x64.tar.gz
      This creates: /opt/java/jdk1.7.0_04/...
  2. self extracting binary RPM jdk-6u17-linux-x64-rpm.bin
    Install:
    • Allow permissions to execute the binary package: chmod +x jdk-6u17-linux-x64-rpm.bin
    • Execute the binary package: ./jdk-6u17-linux-x64-rpm.bin
    • Creates RPMs:
      • jdk-6u17-linux-amd64.rpm
      • sun-javadb-common-10.4.2-1.1.i386.rpm
      • sun-javadb-core-10.4.2-1.1.i386.rpm
      • sun-javadb-client-10.4.2-1.1.i386.rpm
      • sun-javadb-demo-10.4.2-1.1.i386.rpm
      • sun-javadb-docs-10.4.2-1.1.i386.rpm
      • sun-javadb-javadoc-10.4.2-1.1.i386.rpm
    • Installs RPMs to:
      • /usr/java/jdk1.6.0_17
      • /etc/.java/.systemPrefs
      • /etc/init.d/jexec
      • Derby Database support installs to: /opt/sun/javadb/
        Note: all of the sun-javadb RPMs are related to Derby, the all Java database.
  3. self extracting binary bundle jdk-6u17-linux-x64.bin
    This unpacks to a local directory ./jdk1.6.0_17/
    Do this in directory /usr/java to get a similar installation to the RPM result /usr/java/jdk1.6.0_17
    64 bit Workstation Tip: This option of installing the bundle to a directory of your choice is my preferred installation method for 64 bit Linux workstations as it allows me to install both a 32 bit version and a 64 bit version of Java. On 64 bit Linux Workstations it is typical to use a 32 bit browser which is compatible with the 32 bit Adobe Flash plug-in. Also, only the 32 bit version of Java offers a browser plug-in for applet support.
    Install to:
    • 64 bit Java: /usr/java/64/... (or /opt/java/64/...)
    • 32 bit Java: /usr/java/... (or /opt/java/...)

On 64-bit Linux platforms the 32-bit JDK and 64-bit JDK cannot co-exist when installed from the RPM bundles. One must install one or the other but not both RPMs. You can install as many versions of the ".bin" bundle into distinct directories.

Install:

chmod +x jdk-6uxx-linux-xxxx-rpm.bin
./jdk-6uxx-linux-xxxx-rpm.bin
...
This is where you agree to their license. Press the space bar to scroll down in "More".
Do you agree the the above license terms? [yes or no]
yes
...
          
Hit the space bar to scroll through the agreement or press the letter "q" to skip ahead.

Test program: Test.java

public class Test
{
   public static void main(String[] args)
   {
      System.out.println("Hello world");
   }
}
                
Compile: javac Test.java

(or /usr/java/latest/bin/javac Test.java)
Note that the file name and the class name are the same. This became a requirement back in SDK 1.4. The result of the compile is the file: Test.class

Run:

[prompt]$ java Test
Hello world
(or /usr/java/latest/bin/java Test)

[Potential Pitfall]: Red Hat Enterprise Linux and other Linux systems which install GNU Java may find that this conflicts with the Sun Java installation. You may have to remove this (for example RHEL4):
rpm -e java-1.4.2-gcj-compat-1.4.2.0-27jpp java-1.4.2-gcj-compat-devel-1.4.2.0-27jpp.noarch

The newer RHEL5 uses OpenJDK and is a valid Java distribution based on Java 1.6.0.
Install: yum install java

The Java SDK includes the following commands:

  • javac: Linux Java compiler (i.e. javac program-name.java)
  • java: Byte code interpreter / Java program launcher. (i.e. java program-name Do not include ".class" extension.)
    Test version: java -version
  • appletviewer: Views Java applet embedded in html file. (appletviewer myfile.html)

Java Profiling Tools:

Profiling code is the process of running instrumented code so that one can report on the behavior of the executing software with the intent of improving the performance of execution. Profiling tools will reveal what methods are being executed, how much time is spent executing the methods, what and how many objects have been invoked, how much memory they are using and other details of the execution behavior of the code.

Tools which come with the JDK:
  • java: The JVM has a built-in profiler which is activated with the command line argument "java -prof". This will generate a "java.prof" file in the runtime directory. Other tools can then be used to make sense of the data.
  • jmap: Show memory use. First list processes with jps to find the PID of the process you want to query. Show object count for running process: jmap -histo:live 4172
    Show heap: jmap -heap 4172
    Help: jmap -h
  • jconsole:
    • For Java 6: Start app, find the pid with the command: jps
      and then issue the command: jconsole process-id
    • For Java 5 it requires use of JMX and thus it must be compiled in: java –Dcom.sun.management.jmxremote myprogram
      Run JConsole: jconsole process-id
  • jvisualvm: GUI and self explanatory. Allows you to select the running java process to monitor. Various tabs are available for related output.
Many of these tools require the use of jps to identify the system process id of the Java process. List Java processes: jps -vl
List command options: jps -h

Open Source Profiling Tools:
  • btrace: Compiled into your class files with the BTrace compiler: btracec to instrument your code. Text output only. Documentation
  • eurekaj: Accepts and visualizes btrace output via a broker (EurekaJ proxy) which then sends results via JSON to the EurekaJ Manager.
Commercial Profiling Tools:
  • JProfiler: GUI. JEE, database and thread profiling.


Java Servlet, Application Servers and JSP Servers:

Simply put, Java servlets are like CGI in Java for the dynamic generation of web content. JSP is embedding Java in a web page which is processed by the servlet engine before being served.

Java Frameworks, API:


Java Data Storage: (Databases)

DB and ORM API:

Terms:


Java API for Data Formats and Data Exchange:

Data Exchange Formats:

  • XML:
    • Apache: XML Beans: Program to generate Java source code classes to parse and encapsulate XML based on an XSD schema file and populate a data class. Also generates code to generate XML from a Java data object. Released by BEA to opensource community. (YoLinux.com XmlBeans tutorial)
    • JAXB: Generates Java source code to parse and encapsulate XML. Similar to XmlBeans except that it maps XML to a specific JAXB object which reflects the schema of the XML. XmlBeans allows you to parse and then store or use the data however you would like.
      IBM Developerworks JAXB Tutorials: Part 1, Part 2
      Sun's GlassFish reference JAXB implementation
    • Java: JAXP: XML parser. Included in Java SE 1.6
    • Piccolo: High speed XML parser implementing SAX and JAXP interfaces.
    • Apache: Xerces2: XML parser

  • Binary:

  • Non XML Formats:
    • JSON: JavaScript Object Notation
      • GSON - uses reflection to automatically marshal a Java onject to/from JSON
      • Jackson - API to code translation to/from JSON
    • YAML: serialized, human readable text data
    • EDI: Old/historical data exchange format


Java GUI Components:

The compiled code is not cross platform but use of cross platform GUI frameworks should make the source portable if coded well.

  • SL.com - Sherrill - Lubinski SL-GMS - [Applet demo]
    Dynamic graphic GUI components and controls for real time interfaces and displays. Common ".m1" file graphic framework for C++ and Java. Graphic sources include Visio, bitmaps and DXF. Supports pan, zoom, drill-down and hyperlink capability. Supports input as well as displays. Low weight applets for good performance
  • Quest: JClass Delivered as separate class components to be integrated within ones program. Many are Bean components which can be dragged and dropped within a GUI IDE. Many configurable widgets.
  • Genlogic.com: GLG - Dynamic, data driven visual components. Must use GLG monolithic super class framework within your application. Widgets are used within their class framework. Includes many widgets. Strong support of widgets for process control displays.
  • ILog.com: JViews - Diagramming and data graphing capabilities. Requires use of their super class framework. Few predefined widgets. (just graphs and layout) Developer must develop most widgets.
  • Infragistics.com: JSuite - Access control (ACL), db connection pools, GUI components (calendars, explorer trees, editing components), charting (scatter, bar) Not all components were beans and thus would not integrate with IDE.
  • INT.com: Java components - 2D and 3D data visualization.

Custom Java GUI Components


Java GUI frameworks:

  • SWING - Sun GUI API (written using AWT)
  • AWT - Java's primitive graphics layer.
  • JavaFX - Sun Java GUI description language/presentation layer.

Java GUI's and interaction defined by an XML file. This allows for an infinitely flexible interface.

  • CookSwing - extensive framework supporting AWT, Swing and Bean listeners.
  • JGB - Extensible infrastructure and design. Shows promise for easily reconfigurable GUI layouts.
  • SwiXml - uses javax.swing. Tight code base.
  • WidgetServer - unified GUI toolkit to support web AJAX as well as Swing interfaces.
  • OpenLaszlo - web based UI development for J2EE or servlet containers. UI is AJAX HTML/Javascript or Flash for user interaction.
  • Xoetrope: XUI - web or stand-alone applications
  • Beryl XML GUI - Java Swing apps, J2EE client apps
  • SwingML - web J2EE/servlet and AJAX


Java Connection Architectures and Web Services:

Topologies:

  • client - server: e.g.:
    • WWW: Web browser (client) to web server (server) connection. A click on a web page invokes processing by the server which feeds a response to the web browser.
      Software: Apache web server and CGI
    • Servlets: A JVM used to process Java to perform CGI functionality.
      Software:
    • Web Services:
      • SOAP: client calls a remote process. The requested process and input arguments are encapsulated in XML and passed to the server. The server executes the requested function and passes the results back to the client encapsulated in XML.
      • SOA: Service Oriented Architecture - key components of a SOA include services, dynamic discovery, and messages.
        May integrate the following to locate and invoke the web service:
        1. UDDI: Universal Description, Discovery, and Integration - Find a web service, registry
          Software:
        2. WSDL: Web Services Description Language. - Locate the SOAP service and server
        3. SOAP - The Web services server.

        Software:
        • Apache Axis2: SOAP and WSDL support. The Axis SOAP/WSDL engine servlet runs under Tomcat which is coupled with the Apache web server.
        • Apache CXF: (was XFire) Web services programming framework: SOAP, WSDL, JAX, ...
        • Also see lists above i.e. JBoss, BEA Weblogic, IBM Websphere, Sun, Oracle Application server, ...
      • CORBA: Compact binary transport over IIOP. May use a CORBA name server to locate services. Native Java support.
      • Java RMI: Remote Method Invocation. Native Java support.
  • peer to peer: Two systems or processes passing information between the two.
    • JMS: Java Messaging Service. Supports publish-subscribe communications framework. Subscription via callback methods provided by the subscriber. ActiveMQ is often used as a communications bus for ESB.
      JMS and other message queues:
  • Three tier architectures: J2EE (middleware)
    J2EE Software:
  • ESB: Enterprise Service Bus - a collection of specialized processes (may be distributed) integrated by a common infrastructure which handles communication, interactions, interfaces, authentication, discovery and any other needs of the service bus.
    • BPEL: Business Process Execution Language - Workflow defined in an XML schema, used to invoke web services in the proper order and deliver the results.
      BPEL Software: Apache ODE. (Note project Agila is retired.)
    ESB Software:


Cloud Computing:

Most Cloud computing efforts are available as services purchased through vendors such as Amazon Web Services (EC2: Elastic Computing Cloud) or Google AppEngine.


Java Kernel Support:

Linux has support for Java binaries in the OS. You can execute Java applications and Java Applets just like any other program once the Java Runtime Environment is loaded and the kernel configured.
See:


Real Time Java:

The Java Real-Time System (RTS) runs on the Linux Real-Time kernel. The "Red Hat Enterprise MRG" (Messaging Real-time Grid) is a set of over 50 RPMs which add or replace components of the "Enterprise Linux" release. It includes a real-time kernel, configuration and tuning utilities, performance monitoring tools and documentation. The Red Hat MRG Linux includes software based on the University of Wisconsin's Condor project for high throughput computing. The Red Hat MRG release includes QPID, the Apache group's implementation of the AMQP message queues which greatly improves messaging throughput vs traditional SOA technology.


Dot NET Interoperability and Integration:

Dot NET calls to Java:
  • IKVM: JVM in dot NET including dot NET versions of Java libraries. No support for Java GUI.
Java calls to dot NET: Solution is to share COM object. Make COM object available with regasm.exe then call COM component from Java using JNI.
