Use eclipse to install and develop your own boundle

1. Write the Java file that inherits bundleactivator. The start () function is the entry to the osgi platform call start.

Package com. javaworld. sample. helloworld;

Import org. osgi. Framework. bundleactivator;
Import org. osgi. Framework. bundlecontext;

Public class activator implements bundleactivator {

/*
* (Non-javadoc)
* @ See org. osgi. Framework. bundleactivator # Start (Org. osgi. Framework. bundlecontext)
*/
Public void start (bundlecontext context) throws exception {
System. Out. println ("Hello world !! ");
}
 
/*
* (Non-javadoc)
* @ See org. osgi. Framework. bundleactivator # Stop (Org. osgi. Framework. bundlecontext)
*/
Public void stop (bundlecontext context) throws exception {
System. Out. println ("Goodbye World !! ");
}

}
2. Create a new directory and test the org. Eclipse. osgi_3.5.1.r35x_v20090827.jar (osgi package of eclipse) and Java file under this directory. Go to the directory and compile and modify the class.
Javac-classpath org. Eclipse. osgi_3.5.1.r35x_v20090827.jar COM/javaworld/sample/helloworld/Activator. Java
3. Create a manifest. MF file in the META-INF directory, specify bundle-activator and other settings.

Manifest-version: 1.0
Bundle-vendor: javaworld
Bundle-version: 1.0.0.qualifier
Bundle-Name: helloworld
Created-by: 1.6.0 _ 14 (Sun Microsystems Inc .)
Bundle-Activator: COM. javaworld. sample. helloworld. Activator
Bundle-manifestversion: 2
Import-package: org. osgi. Framework; version = "1.3.0"
Bundle-symbolicname: COM. javaworld. sample. helloworld
4. Package
Jar-CFM com. javaworld. sample. helloworld. activator. Jar helloworld. mf com/javaworld/sample/helloworld/Activator. Class
5. Enter the directory at the DOS prompt and start osgi
Java-jar org. Eclipse. osgi_3.5.1.r35x_v20090827.jar-Console
6. Install and create a bundle
Osgi> Install file: COM. javaworld. sample. helloworld. activator. Jar
7. Start bundle according to the ID. If the ID is 1
Osgi> Start 1
8. Stop bundle
Osgi> stop 1
9. Uninstall bundle
Osgi> uninstall file: COM. javaworld. sample. helloworld. activator. Jar
