Starting java programs as a windows service (or a unix deamon)

Introduction

you can easily start your java program as a part of the OS loading sequence by using one of many available tools today and i can see that Java Service Wrapper is the easiest way to do so...
the best thing about this tool is that you configure a property file for your windows service and use the same file for installing unix deamon....

Downloading and Installing

there are three packages of Java Service Wrapper: professional, standard and community the last is free under GPLv2
extract the file to a folder(this folder will be referenced as ${wrapper_home} )

Your Side

Develop, compile and jar your java desktop application that for sure got a class with the main method...

Wrapper Side

the wrapper comes with an example service, all you have to do is the following
  1. edit the file ${wrapper_home}\conf\wrapper.conf (will be described in details shortly)
  2. use the batch files located at ${wrapper_home}\bin to install, start, stop, suspend, resume and uninstall the service
  3. add and jars to ${wrapper_home}\lib (including your application)

Editing the wrapper.conf

the wrapper.conf is a simple java property file, edit the following:

wrapper.java.mainclass=org.tanukisoftware.wrapper.WrapperSimpleApp
that is a simple wrapper for your application, it comes out of the box

wrapper.java.classpath.1=../lib/wrappertest.jar
wrapper.java.classpath.2=../lib/wrapper.jar
wrapper.java.classpath.3=../lib/JMXservices.jar
wrapper.java.classpath.4=../lib/jbossall-client.jar
that to include any jars to the class path, do not touch 1 and 2, start adding after that

wrapper.app.parameter.1=com.harf.jmx.Initializer
that is your class with the main method you can pass params to your main from here like wrapper.app.parameter.2
but remember that your class must be the first argument

Name of the service
wrapper.ntservice.name=JMXServices

Display name of the service
wrapper.ntservice.displayname=JMX Harf Services

Description of the service
wrapper.ntservice.description=A JMX based Utility System

Mode in which the service is installed. AUTO_START or DEMAND_START
wrapper.ntservice.starttype=AUTO_START

now go ahead install & start your service
execute "InstallTestWrapper-NT.bat"
then "StartTestWrapper-NT.bat"

Asynchronous Vs. Synchronous Communications

Synchronous (One thread):   1 thread -> |<---A---->||<----B---------->||<------C----->| Synchronous (multi-threaded):   thread A -> |<---A---->| \ thread B ------------> ->|<----B---------->| \ thread C ----------------------------------> ->|<------C----->|

WebSphere MQ Interview Questions

What is MQ and what does it do? Ans. MQ stands for MESSAGE QUEUEING. WebSphere MQ allows application programs to use message queuing to participate in message-driven processing. Application programs can communicate across different platforms by using the appropriate message queuing software products. What is Message driven process? Ans . When messages arrive on a queue, they can automatically start an application using triggering. If necessary, the applications can be stopped when the message (or messages) have been processed. What are advantages of the MQ? Ans. 1. Integration. 2. Asynchrony 3. Assured Delivery 4. Scalability. How does it support the Integration? Ans. Because the MQ is independent of the Operating System you use i.e. it may be Windows, Solaris,AIX.It is independent of the protocol (i.e. TCP/IP, LU6.2, SNA, NetBIOS, UDP).It is not required that both the sender and receiver should be running on the same platform What is Asynchrony? Ans. With messag...

Advantages & Disadvantages of Synchronous / Asynchronous Communications?

  Asynchronous Communication Advantages: Requests need not be targeted to specific server. Service need not be available when request is made. No blocking, so resources could be freed.  Could use connectionless protocol Disadvantages: Response times are unpredictable. Error handling usually more complex.  Usually requires connection-oriented protocol.  Harder to design apps Synchronous Communication Advantages: Easy to program Outcome is known immediately  Error recovery easier (usually)  Better real-time response (usually) Disadvantages: Service must be up and ready. Requestor blocks, held resources are “tied up”.  Usually requires connection-oriented protocol
