I’ve been working with OSGi for quite awhile and have faced a problem "Workbench has not been createt yet" issues. I was getting this error, When i was trying to run OSGI plugin from Eclipse and I guess many of you must have face this problem. So i am writing a little bit about how to resolve this issue so others don’t repeat the same mistakes. From a good article on eclipsezone: java.lang.IllegalStateException: Workbench has not been created yet This usually comes when someone tries to run a Java application against an OSGi bundle with java -classpath .... . It really means that the workbench plug-in hasn't started yet, and so calls to getWorkbench() fail. This is essentially a race condition, and can be solved by either expressing an explicit dependency on that bundle or bumping up that bundle to a higher start level than the workbench. Generally not seen, but if it is, that's what's happening. Now to set the bundle to a higher start level than the work...

Introduction: Ant (originally an acronym for Another Neat Tool), is a build tool with special support for the Java programming language but can be used for just about everything.Ant is platform-independent; it is written purely in Java. Ant is particularly good at automating complicated repetitive tasks e.g. compiling source code, running software tests, creating jar files, javadocs, etc. and thus is well suited for automating standardised build processes. A build process typically includes:      -the compilation of the Java source code into Java bytecode      -creation of the .jar file for the distribution of the code      -creation of the Javadoc documentation Ant accepts instructions in the form of XML documents("build.xml") thus is extensible and easy to maintain. Installation: Linux (Ubuntu / Debian) On Debian /Ubuntu use "apt-get install ant" to install it. Windows Download Apache Ant from http://ant.apache.org/ . Extra...
